In one embodiment, the swell packer includes a substantially tubular member; and a seal element disposed on the substantially tubular member, the seal element including an elastomeric swellable material that comprises: a closed cell material having a plurality of pore spaces therein; and a compressible gas located within at least a portion of the plurality of pore spaces.

A method for 3D printing a patient-specific bone implant having variable density, in various aspects, comprises: (1) providing a thermoplastic polymer composition comprising: (A) between about 20% and about 50% bioactive agent by weight; (B) between about 0.5% and about 10% chemical foaming agent by weight; and (C) balance structural polymer by weight; (2) receiving, by computing hardware, a scan of a bone, the scan comprising at least a 3D image of the bone and radiodensity data for the bone; and (3) causing, by the computing hardware, a 3D printer to form the patient-specific bone implant from the 3D image using the thermoplastic polymer by modifying a 3D printing temperature of the 3D printer during printing of the patient-specific bone implant such that each portion of the patient-specific bone implant is produced at a temperature that corresponds to a desired density defined by the radiodensity data for the bone.

A system for producing foams for prosthetics and orthotics include a heated housing that stores monomer containers, temperature-controlled hoses separately coupled with the containers and configured to receive monomers from the containers, a dispensing gun assembly fluidly coupled with the containers by the hoses, and a computer controller configured to control a dispensing time period during which the monomers are dispensed from the containers and through the hoses to the dispensing gun assembly and dispensed out of the dispensing gun assembly as a polymer foam. The controller is configured to stop dispensing of the polymer foam out of the dispensing gun assembly upon expiration of the dispensing time period.

To provide a new foam molding method and injection molding machine capable of solving variation in a wall thickness and a foamed state, sensor corrosion, a complexity of sensor positioning, and the like. The above-described problem is solved by a foam molding method comprising a resin filling step of filling a mold (2), clamped by a predetermined mold clamping force (Pc), with a resin (R) at a predetermined molding injection pressure (Pi), a filling stopping step of stopping the filling of the resin (R) when, while monitoring a mold gap (Lm) of the mold (2) during the filling, a predetermined mold gap value set in advance is reached, a surface layer curing and filled resin cooling step of curing a surface layer of the resin (R) for a certain time and cooling the filled resin (R) for a certain time after the filling of the resin (R) is stopped, a volume controlling step of controlling a volume increase by reducing the mold clamping force after curing the surface layer of the resin (R) for a certain time, and a taking out step of taking out a foam-molded product by opening the mold (2) after the volume control is performed and after cooling the filled resin (R) for a certain time.

Traditional climbing is being sought out by more indoor climbers, however the issue that has arisen is that the only way to learn the method is through trial and error in the outdoors on real rock. An indoor-traditional climbing device (I-TCD) makes it possible to learn how to climb Traditionally in a safe environment with hands on instruction. Provided herein is a cover/shield for an I-TCD that allows not only for the placement of multiple kinds of gear within the I-TCD body, but it allows the climber to fall on that gear placement safely to determine the quality of their gear placement, without the risk of falling upon the I-TCD body. Therefore, the cover/shield provides an angled feature to reduce direct impact injuries while increasing the opportunity for climbers who wish to learn how to climb traditionally.

The present application relates to a thermally expandable composition containing at least one peroxide cross-linking polymer, at least one peroxide, at least one polysaccharide and at least one endothermic, chemical blowing agent; as well as to shaped bodies containing said composition and to a method for sealing and filling voids in components, for strengthening or reinforcing components, in particular hollow components, and for bonding mobile components using shaped bodies of this type.

The method of making a compressed biocomposite body includes compressing a mass of biocomposite material comprised of discrete particles and a network of interconnected glucan-containing mycelia cells in the presence of heat and moisture into a compressed body having a density in excess of 18 pcf. Compression may take place batch wise in a press or continuously in a path of narrowing cross-section defined by a series of heated rollers.

A method of forming a shaped foamed polymer article and articles obtained from said method.

A manufacturing method for a car safety seat includes the following steps: providing a mold and disposing a main body of the car safety seat into the mold, and injecting a foam material into a cavity of the mold and foaming the foam material so as to form a flexible layer integrated with the main body. A pressure in the cavity is between 1.5 bar and 5.0 bar. The manufacturing method disposes the main body into the mold and directly forms a flexible layer on the main body, so that the flexible layer ensures safety and comfort of the car safety seat while saves the necessity to dispose a seat pad or a cushion and fixing structures on the main body, and thereby reduces the cost and the work-hour of assembly, and the overall weight of the car safety seat can be reduced by omitting the fixing structures.

A manufacturing method for a child carrying device includes the following steps: providing a mold and disposing a main body of the child carrying device into the mold, and injecting a foam material into a cavity of the mold and foaming the foam material so as to form a flexible layer integrated with the main body. The manufacturing method disposes the main body into the mold and directly forms a flexible layer on the main body, so that the flexible layer ensures safety and comfort of the child carrying device while saves the necessity to dispose a seat pad or a cushion and fixing structures on the main body, and thereby reduces the cost and the work-hour of assembly, and the overall weight of the child carrying device can be reduced by omitting the fixing structures.
