Abstract: A gas filter comprising a tube open at one end for insertion of the element and a threadedly connectectable end cap for closing the housing are disclosed. Attached to the end cap and also to the opposite end of the housing are receptacles for receiving the ends of the filter therebetween. The receptacles are faced with a resilient seal to make the connection between the receptacle and the filter air-tight as the end cap is tightened. After effecting the seal at both ends of the filter, a pair of hollow hypodermic needles pierce membranes that closed off the ends of the filter. The other ends of the needles extend out of the housing at both ends allowing the connection of an inlet and outlet gas hose thereby establishing fluid communication between the hoses and permit gas to flow through the filter for cleansing. Two embodiments are disclosed.

Abstract: A female electrical connector formed of sheet metal to receive a cylindrical male pin. The connector is configured as hyperboloid of revolution with the generatrices comprising a plurality of flat and straight beam members disposed between a pair of cylindrical ferrules. The beam members bear against the inserted pin along a contact length so the bearing therebetween is a surface of each beam member partially wrapping around the pin to effect electrical continuity therebetween.The beam members are automatically formed when the ferrules are rolled into cylinders without any part of the tooling touching the beams.

Abstract: An electrical connector contacts assembly having a solid elongated pin member and a hollow socket member each having like cross-sections for closely removably inserting the pin through the socket. The socket body is twisted into a helical configuration while the pin is straight-sided. The assembly of the members reconfigures the more resiliant socket into the configuration of the pin setting up torsional stresses that create a uniformly distributed torsional force load between the pin and socket for achieving low electrical resistance therebetween.

Abstract: A nursing blanket for use by a nursing mother to shield her breast from public view while feeding her infant. The blanket comprises a square of woven cloth with an elastic, garter-like loop affixed near one corner of the cloth. In use, the mother inserts her arm through the loop and pulls the loop up over the point of the shoulder thereby disposing the cloth down the length of the arm. She then cradles the infant in same arm and drapes a portion of the cloth over most of her chest including her breast and over the infant's head and upper body. She can then reach under the cloth to bare her breast and offer it to the infant. In this way she effectively screens her breast from view and is able to discretely nurse in public.

Abstract: A device for inducing and maintaining an erection of the male genital organ comprising a tubular member that is open at one end and receptive of the organ. A pump is affixed to the tube and, upon activation, withdraws air from the tube causing blood to flow into the inserted organ thereby enlarging and rigidizing it. When the organ has attained the desired erection, the pump is stopped and an elastic constriction band is disposed over the base of the organ. The band prevents the return flow of blood from the organ thereby capturing the erection. Simultaneous with the application of the band, a valve is allowed to open permitting outside air to enter the tube and equalize the pressure to make it easier to remove the device from about the erected organ.

Abstract: A container for retaining artist's paints or the like and for preventing same from drying or hardening during storage in the container comprising an open top box including a base and side walls and a cover that can be superposed over the box opening. The underside of the cover includes a resilient gasket of foam rubber or plastic that is located to bear against the edges of the side walls when the box is closed. A thin sheet of polyethylene film is disposed over the gasket to provide an easily cleanable surface and to aid in the conformance of the gasket to side wall edges.Located within the closed box is a moisture resevoir such as wetted sponge placed in fluid communication with the paints stored in the container.

Abstract: A method for fixturing two or more workpieces in a desired positional relationship with respect to one another by utilizing a moldable and heat resistant work holding material to position and support the workpieces. The work holding material may subsequently be hardened to provide a permanent and reusable fixture.
