Abstract: This disclosure pertains to an aid for invalids facilitating their ability to be seated and unseated from a water closet utilizing a pair of horizontally disposed arm rests and a hinged commode seat whose elevation and angular position above the water closet is under the manual control of the invalid. A manually operated lever enables a spring to bias the arm rests and the seat in an uppermost position for use by the invalid in the standing position. Manipulating the lever permits the arm rests to descend and the seat to assume a horizontal position with the spring resisting the downward forces exerted on the arm rests and the seat, by the user, as he is gently lowered into a seated position. Re-manipulation of the lever causes the spring to urge th arm rests in an upward position, and the seat to assume a near vertical position thereby aiding the invalid to achieve a standing posture.

Abstract: This disclosure teaches a method for integrated finishing and compressive preshrinking of a high-shrinkage fabric. The fabric is brought damp from being finished to being compressively preshrunk, rather than according to universally recognized procedure of causing all goods which are to be compressively preshrunk to be in their dry state before the compressive-preshrinking operation. A padder is here employed to impregnate the fabric with finishing liquid, then a series of hot cans reduce the moisture content of the fabric to a range of from 10 to 30%. A moisture content of 15% is preferred. In blended fabrics of cellulosic and man-made fibers, the need for this moisture content is only in the cellulosic component. From the hot cans the fabric is introduced to a compressive-preshrinking unit and the fabric is subsequently dried in a felt-belt dryer.

Abstract: Wire feeding means which can be used with conventional wire crimping presses are disclosed. A movable funnel is used to precisely position the wires in a crimping station. Movement of the funnel in synchronization with the terminal feed mechanism extracts the wire from the crimping station and relative movement of the wire and the funnel releases the wire from the funnel.

A sensor which detects the presence of the wire in the channel is located between a barrel and the crimping station. These elements combine to move the uncrimped wire longitudinally into the crimping station and then move the crimped wire laterally out of the crimping station.
