Title: Method for welding conduits of thermoplastic material, and device therefor
Inventor: THALMANN ALFRED
IPC: B29C65/22
Filed: 1983-12-23
Granted: 1986-08-14
Abstract: A system for heat-sealing thermoplastic conduits involves a thermoplastic sleeve surrounding an electrically conductive heating wire arranged in a coil. A bridging conductor is located adjacent the heating element, but is separated from it by an insulation layer of predetermined thickness. When the sleeve is heated by supplying electric power to the heating element, the entire heating element generates heat during a first phase in which fusion pressure is applied between the sleeve and pipes being connected. The bridging connector is forced into contact with selected coils of the heating element to initiate a second phase. In the second phase, the heat produced in the area of the selected coils is automatically reduced by short circuiting such coils.

Title: Pressure swing adsorption process and apparatus
Inventor: DOSHI KISHORE JASRAJ
IPC: B01D53/04
Filed: 1983-04-20
Granted: 1988-04-21
Abstract: A high pressure gas stream having a hydrogen content of up to about 90 mol percent is passed to a separator containing a permeable membrane capable of selectively permeating hydrogen. The separator is used to achieve a bulk separation of the desired hydrogen from impurities contained in the gas stream. The separated hydrogen is recovered at a reduced pressure and is passed to a pressure swing adsorption system adapted for operation at said reduced pressure. The off-gas from the separator is recovered essentially at the higher pressure of the gas stream. A portion of the off-gas is throttled to a lower pressure, with appropriate power recovery, and is passed to the pressure swing adsorption system as a co-feed gas, thereby contributing to the recovery of purified hydrogen product and to a reduction in the operating costs for the desired hydrogen separation and purification. The remaining off-gas is recovered as a relatively high pressure fuel or feed gas for other purposes.

Title: Method of making polyimide foam precursor
Inventor: GAGLIANI JOHN
IPC: C08J9/12
Filed: 1984-05-01
Granted: 1989-04-27
Abstract: Methods of making low density modified polyimide! polyimide-amide foams and the resulting compositions. An N-substituted aliphatic imide is prepared by reacting a suitable aromatic dianhydride with a suitable oxime. A polyimide forming material is prepared by dissolving the N-substituted aliphatic imide in an esterifying solvent, then adding a suitable aromatic diamine. This material is dried to a powder. A suitable hydrated compound which is stable up to at least about 100°C. is mixed with the powder. A foam is then produced by heating the material to reaction temperature for a period sufficient to produce a stable foam. The material melts, then spontaneously expands into a foam which becomes self supporting and cures to a resilient flexible foam. The addition of the hydrated compound is found to result in an exceptionally low density foam. Depending upon heating conditions, a polyimide, polyimide- amide or mixture thereof may be produced, resulting in foams having selectively variable physical properties.

Abstract: An apparatus and method is described for applying epidermal growth factor (EGF) for achieving healing enhancement at a wound site. The human source of epidermal growth factor, designated as hEGF, is applied from the synthetic resin matrix system of this invention, and which comprises a polymer, such as poly(2-hydroxyl ethyl methyl methacrylate), referred to as PHEMA, an organic solvent, such as polyethylene glycol (PEG), and a hydrogen binding plasticizer, such as dimethylsulfoxide (DMSO). The plasticizer regulates the set-up time of the synthetic resin, so that the more plasticizer present, the shorter the set-up time. The dressing, once formed, and having the healing enhancer contained therein, may be sealed within various backing sheets, in order to preserve its aseptic condition. When ready for use, one of the backing sheets may be peeled away to expose the resin pad with the embodied healing enhancer, ready for application to the wound site.

Granted: 1989-03-16
Abstract: A peanut butter press feeding mechanism has a peanut supply hopper which is controlled by a release gate to supply a volumetric feeder. The volumetric feeder ensures that each of four intermediate holding hoppers at a peanut butter press are filled to capacity. A second release gate controls the outlet of the volumetric feeder, which releases the peanuts into a totalizing scale which weighs peanuts supplied to all four of the intermediate holding hoppers. The totalizing scale supplies peanuts to a conveying arrangement having diverting gates which supply the appropriate intermediate holding hopper with a full supply of peanuts. During operation of the peanut butter press, a predetermined amount of oil is removed from the peanuts based upon the total weight of the peanuts used. This is necessary since merely knowing the volume of the peanuts used is insufficient due to the fluctuations in density of each batch of peanuts.

Abstract: A coater includes a gravuer roll rotatably mounted in a fountain of coating material. A doctor blade engages the roll and doctors material from the surface. A curved predoctor deflector opens upstream of the material and has an inclined upper edge at about the level of the material to form a wedge-shaped gap forcing material into the roll. The deflector bottom is spaced from the fountain bottom to define a return path.
