Mineralized collagen-based femoral head support device
A femoral head support device, in particular a mineralized collagen-based femoral head support device applicable to the treatment of early osteonecrosis of femoral head. The device is made from a dense, homogeneous organic/inorganic composite, wherein the organic phase includes collagen and inorganic phase includes nano calcium phosphate salt, and the device is of a cylinder having an upright through hole and also has a support strength of up to 4000-6000N. By implementing a method for manufacturing such mineralized collagen-based femoral head support device, the mineralized collagen-based femoral head support device with mechanical properties equivalent to human cortical bone can be manufactured; and the mineralized collagen-based femoral head support device can meet the demand for clinical treatment of early osteonecrosis of femoral head to avoid the continuous collapse of necrotic femoral head.
Method for manufacturing three-dimensional products from a fiber-containing material using at least one forming tool and forming tool
A method for manufacturing three-dimensional products with at least one inclined product portion made of a fiber-containing material using at least one forming tool and a forming tool are described. Vibrations are introduced via a device and this results in an improved compression of fiber-containing material in the region of inclined portions.
Food container and methods and systems for manufacturing food containers
A pressware product includes a top piece and a bottom piece. The top piece includes a planar central portion, a sidewall extending from the central planar portion, and a flange extending horizontally from the sidewall. The flange includes a slot and a radially extending top groove. The bottom piece cooperatively defines an inner space with the top piece. The bottom piece includes a planar central portion, a sidewall extending from the central planar portion, and a flange extending horizontally from the sidewall. The flange includes a locking flap configured to engage the slot of the top piece and a radially extending bottom groove. The radially extending bottom groove cooperatively defines a channel with the top groove so that the channel is in fluid communication with the inner space.
Adjustment of twist to optimize moulds and the shaping of textile architectures
An installation for compacting strands or a preform including strands, the strands or the preform including at least a first portion in which the strands are twisted at a first angle and a second portion in which the strands are twisted at a second angle different from the first angle, the installation including a mould which includes the strands or the preform, and wherein the mould has at least a first part in which the first portion of the strands or of the preform is disposed, having a first thickness and a second part in which the second portion of the strands or of the preform is disposed, having a second thickness different from the first thickness.
Method of shaping a tampon for feminine hygiene
A process of forming a shaped, dimensionally stable tampon includes the steps of: radially compressing a tampon blank to form a dimensionally stable intermediate pledget having an intermediate pledget diameter and a longitudinal axis; placing the intermediate pledget into a hollow carrier and inserting the intermediate pledget and hollow carrier into a mold; urging the intermediate pledget into the mold via a ram bearing on an end of the intermediate pledget contained within the hollow carrier and withdrawing the hollow carrier from the mold to permit the exposed end of the intermediate pledget to substantially fill the mold and to form the shaped, dimensionally stable tampon; removing the shaped, dimensionally stable tampon from the mold; and enclosing the shaped, dimensionally stable tampon in a primary package that conforms to the shape thereof. The mold has an access opening through which the hollow carrier can be withdrawn.
Method of forming a cured elastomer and golf balls
A cured elastomer golf ball component is made by heating an elastomer compound containing an ethylenically unsaturated elastomer, an ethylenically unsaturated monomer, and first and second free radical initiators to a first crosslinking temperature T.sub.1 in a compression mold and partially crosslinking the elastomer, then heating to a second crosslinking temperature T.sub.2 and curing the elastomer component of the golf ball. Either: (i) the first initiator has a half-life of about 0.2-5 minutes at T.sub.1, the second initiator has a half-life of about 0.2-5 minutes at T.sub.2, and T.sub.2 is higher T.sub.1 by at least about 30 C.; or (ii) the second initiator's one-minute half-life temperature is at least about 30 C. higher than the first initiator's one-minute half-life temperature, T.sub.1 is within about 20 C. of the first initiator's one-minute half-life temperature, and T.sub.2 is within about 20 C. of the second initiator's one-minute half-life temperature.
Mold plate and method of molding golf ball core
A mold for manufacturing hemispherical sections for a golf ball includes a mold plate and a movable insert. The mold plate includes a first surface. The movable insert includes a second surface. The moveable insert is connected to the mold plate. The first surface of the mold plate and the second surface of the movable insert may move relative to one another during molding of the hemispherical section for a golf ball.
METHOD OF SHAPING A TAMPON FOR FEMININE HYGIENE
A process of forming a shaped, dimensionally stable tampon includes the steps of: radially compressing a tampon blank to form a dimensionally stable intermediate pledget having an intermediate pledget diameter and a longitudinal axis; placing the intermediate pledget into a hollow carrier and inserting the intermediate pledget and hollow carrier into a mold; urging the intermediate pledget into the mold via a ram bearing on an end of the intermediate pledget contained within the hollow carrier and withdrawing the hollow carrier from the mold to permit the exposed end of the intermediate pledget to substantially fill the mold and to form the shaped, dimensionally stable tampon; removing the shaped, dimensionally stable tampon from the mold; and enclosing the shaped, dimensionally stable tampon in a primary package that conforms to the shape thereof. The mold has an access opening through which the hollow carrier can be withdrawn.
Flexible implement grip
A flexible tubular elastomeric grip for an implement to be manually swung with force and speed, such as a golf club is provided. A flexible tubular member molded of elastomeric material has an open end for receiving the club shaft with a hardness in the range of 38-55 on the Shore A scale and has a substantially closed end which has a greater hardness in the range of 65-100 on the Shore A scale. The closed end may be integrally molded with the tubular member or as one piece or formed pre-cured and adhesively received in the cavity after molding. An open cavity formed in the closed end has received therein an insert which may be a transducer, RFID tag, tracking device, speed/acceleration sensor or decorative item. In one version, a peripheral rim lip retains and secures the insert in the cavity. In another version, inwardly extending arms are formed integrally with the flexible tubular member to retain and secure the insert. Alternately, the arms may be connect to form a bridge over the cavity to retain and secure the insert.
Method for Producing a Gasket on a Component and Shaping Tool for Use in such a Method
The invention relates to a method for producing a gasket on a component using a shaping tool, wherein the material used for the gasket is a UV-curable sealing or gasket material, and wherein the shaping tool comprises an upper face and a lower face and at least one cavity which is open toward the lower face of the shaping tool and which is provided for filling with the gasket material, and wherein furthermore the shaping tool is made of a UV-transparent material at least in the region of the cavity, comprising the following steps in the order indicated: 1. introducing the gasket material into the cavity of the shaping tool; 2. placing the component onto the lower face of the tool provided with the gasket material; 3. pressing the component onto the tool; 4. curing the gasket material by way of UV irradiation; and 5. removing the tool from the component and the gasket joined thereto.
The invention further relates to a shaping tool for use in such a method.
