Abstract: A body implantable medical infusion system including an infusate reservoir, a system for regulating infusate discharge and a catheter for delivery of discharged infusate to the desired infusion site. An unregulated infusate discharge is prevented, in a preferred embodiment, by a normally open valve positioned intermediate the pump and the catheter, the valve closing in response to the sensing of unregulated infusate. A sensor, to which the valve responds, may be positioned at the output of the pump or at any other location within the system to sense infusate leakage. The valve may be additionally closed in response to an externally generated signal.
Abstract: A radio-controlled toy has a transmitter designed to transmit a signal amplified and modulated with a low-frequency square signal by the supply of power effected by closing a switch and a receiver having a receiving circuit portion and a forward-to-reverse switching control. The transmitter may include an astable multivibrator for producing a low-frequency square signal and a crystal oscillation circuit. The forward-to-reverse switching control is designed such that when no signal is received, a d.c. motor turns forward and when a signal is received, the d.c. motor turns in reverse.

Abstract: An identification snap for attachment to woven material such as clothing includes a first plate member bearing identifying indicia on an outer surface and a post projecting from an inner surface, and a second plate member including a centrally disposed orifice extending from an inner face to an outer face, the orifice being defined by a substantially frusto-conical wall which converges toward the inner face. The orifice is sized to receive the post of the first plate member in an interference fit so that when the first plate member is placed against the fabric of a garment with the post extending through it and the second plate member is placed on the opposite side of the fabric, the post can be received within the orifice, thereby joining the first and second plate members and clamping the fabric therebetween.
Abstract: A machine for the manufacture of a panel file for the storage of flat, flexible data elements is herein disclosed. A sheet of flexible resilient material is unrolled from an arbor. The material is cut into strips and rolled onto reels. The strips are substantially narrower than the depth of the pockets to be formed in the panel file. The reels are mounted on a strip aligning mechanism so that as the strips are unloaded from the reels they are in a parallel overlapping relationship. The strips are then pulled through an accumulator and placed in a heat sealing die. In the heat sealing die, the strips are joined to each other proximate the ends thereof to form a layered panel of overlapping pocket entrances. Also in the heat sealing die, a pocket forming sheet is attached to the back of the layered panel of strips.
Abstract: An animated display showing the Nativity scene. Human figures representing the Wise Men, shepherds, etc., move past the crib containing the infant Jesus. Each figure pauses, turns towards the crib, bows, turns back, and then moves away. The pausing action is created by a drive gear with some missing teeth. The turning action is created by two racks which mesh sequentially with a gear on which each figure is mounted. The bowing motion is created by a hinge mounting for each figure, and a push-rod actuation mechanism.
Abstract: A signage system includes a frame including a vertical support plate having horizontal sign mounting flanges on at least one side of the plate. Removable plate-shaped lettering inserts are mounted on the frame by mounting flanges on the back surface of the lettering inserts that mate with the mounting flanges on the support plate. The flanges are engaged by fitting the mounting flanges of the lettering insert endwise on the ends of the mounting flanges for the support plate and sliding the lettering inserts horizontally onto the frame. Removable end caps cover the ends of the frame and lettering inserts, with the end caps including at least two opposed resilient fingers that fit over and press resiliently against the opposite sides of the support plate to hold the end caps on the frame. The end caps are formed by joining together two identical halves.
Abstract: The disclosed structure holds a rectangular thin-piece such as a photographic transparency on a base sheet between at least two holding portions formed on the base sheet and a thin-piece seat being recessed relative to the holding portions. A push-in area is formed on the base sheet adjacent to both the seat and at least one of the holding portions. One edge of the thin-piece is once pushed in between the push-in area and the holding portion adjacent thereto to an extent sufficient for clearing the thin-piece from the remainder of the holding portions, and then the thin-piece is moved back from the push-in area onto the seat where an abutting member abutts the thin-piece to keep the thin-piece in position. A plurality of the thin-piece holding structures are formed on one base sheet to form a slide filing sheet.
Abstract: The display device includes an ordinary mailing envelope with a slot in the back. A stiff fiber-board card is inserted into the envelope. The card has a tab or tongue which is pushed outwardly through the slot in the back of the envelope to serve as a prop to support the envelope in the manner of a display card for counters or shelves in stores, etc. On the front of the envelope is printed the message to be displayed. Alternatively, the front of the envelope is fully or partially transparent, and photographs or other graphic matter are inserted into the envelope with the picture showing so that the display device serves as a relatively simple and low-cost picture frame.
