The present disclosure provides a resin seal member capable of reducing the cost while preventing a reduction in the sealing performance due to an influence of heat or pressure in accordance with a usage environment. The present disclosure provides a resin seal member (20) including a foamed resin part (13). This resin seal member (20) includes a convex part (12b) having a foaming ratio lower than that of the foamed resin part (13). The convex part (12b) is provided in an end part of the foamed resin part (13). The resin seal member (20) is able to reduce the cost while preventing the reduction in the sealing performance due to the influence of heat or pressure in accordance with the usage environment.

An injection molding apparatus for forming a gasket around an edge of a glass is provided. The injection molding apparatus includes: an injection mold die; a fixing component, disposed inside the injection mold die and adapted for fixing the glass inside the injection mold die; a detection unit, mounted to the injection molding apparatus and adapted for detecting an image or vibration of the glass; a determination unit, coupled with the detection unit and adapted for determining whether the glass breaks based on a detection result of the detection unit. The apparatus can determine whether the glass breaks, such that the risk of scratching the injection mold die by glass breaking may be reduced. Therefore, the injection molding yield can be improved, the time for repairing the injection mold die may be reduced and a service life of the injection mold die may be prolonged.

A packer or plug for use in a wellbore includes: a tubular mandrel made from a composite material including a pyrotechnic composition; an expandable seal disposed on an outer surface of the mandrel; and an igniter operable to initiate combustion of the mandrel.

An ultrasonic sealing device, including a horn having a sealing surface, an anvil having a sealing surface, at least one of the horn and the anvil being moveable to engage the respective sealing surfaces, the sealing surfaces of the horn and the anvil including a plurality of protrusions and a recess between each of the protrusions, each of the protrusions having a flat distal surface and sloped sidewalls with curved edges therebetween and each of the recesses including a flat recess surface with curved edges, wherein, upon engagement of the sealing surface of the horn with the sealing surface of the anvil, the flat distal surfaces of each of the protrusions on each of the sealing surfaces engage corresponding ones of the flat recess surfaces of each of the recesses on each of the sealing surfaces and define gaps between the sloped sidewalls of each adjacent protrusion.

Apparatus and methods for additively manufactured O-ring grooves are presented herein. An O-ring groove is additively manufactured to have a vertical face, bottom face, and an opposite face. By additively manufacturing the opposite face to be outwardly facing with an obtuse angle, the O-ring groove can be built without the need for support structures, thereby reducing post processing steps and manufacturing cost.

A system for processing elastomeric load rings may include an elastomeric load ring defining an initial width. The system may also include a fixture assembly configured to receive the load ring between first and second clamp members. The second clamp member may be spaced apart from the first clamp member such that a gap is defined between the clamp members when the load ring defines the initial width. The fixture assembly may also include a load member configured to apply a compressive load through the first clamp member and/or the second clamp member such that the load ring is compressed between the clamp members. When the load ring is heated, a spring force of the load ring may be reduced as the load ring is compressed between the clamp members such that the initial width of the load ring is reduced to a final width.

A system for monitoring biometric signals of a user comprising: a garment configured to be worn by the user and comprising a mounting module having an array of connection regions; a set of biometric sensors coupled to the garment and configured to communicate with the array of connection regions to receive and transmit biometric signals indicative of muscle activity of the user; and a portable control module configured to couple to the garment in a first configuration and to decouple from the garment in a second configuration and comprising: a housing comprising an array of openings; a set of contacts, each including a first region that seals at least one of the array of openings and couples to at least one of the array of connection regions in the first configuration, and an electronics subsystem coupled to the housing and in communication with a second region of each contact.

The invention relates to a method and a device for demolding annular elastomeric molded parts from a mold core of an injection mold which has an inner mold core (1) and outer mold jaws and in which the molded parts (9) are produced parallel to one another in annular mold cavities (5) of the mold core (1). According to the invention, after removal of the outer mold jaws, the mold core (1), which contains the produced elastomeric molded parts (9) on the surface thereof, is set at such a high rotational speed about the longitudinal axis thereof that the internal diameter of the elastomeric molded parts (9) is increased because of centrifugal force to such an extent that the molded parts (9) are released from the mold cavities (5) and can be removed from the mold core (1) in the axial direction (10) while they are still rotating.

A seal for a vacuum lifter and method of manufacture wherein the seal has a continuous unbroken outer fluid resistant skin of elastomer which forms a boundary around a homogeneous cellular structure with no interior seams or joints.

A system for treating a tissue site includes a reduced-pressure source to apply reduced pressure, a manifold in fluid communication with the pressure source to provide reduced pressure to the tissue site, and a drape for adhering to the tissue site to cover the tissue site and the manifold. The drape includes an adhesive layer for sealing the drape to the tissue site to create a sealed space having the manifold therein, and a non-adhesive layer formed from a portion of the adhesive layer. A method for manufacturing a medical drape includes providing a sheet of adhesive material and treating a side of the sheet of adhesive material to form a non-adhesive layer and an adhesive layer. The method laminates a release liner adjacent the adhesive layer.
