Abstract: An electronic door control system is disclosed having a d.c. motor rotatable in one direction for opening a door and in the opposite direction for closing the door. One or more semiconductor devices (preferably SCR's) supply d.c. power to the motor from an a.c. power source when rendered conductive. A polarity selecting circuit controls the polarity of d.c. power supplied to the motor and thus its rotational direction. A sensor (e.g. floor mat) senses body pressure near the door to enable conduction of the semiconductor device and provide a first d.c. power polarity for a predetermined period to open the door. A circuit reverses the polarity after the door is opened, thereby closing the door. A speed control circuit responsive to counterelectromotive force developed by the motor effectively controllably varies the conductivity of the semiconductor device in a sense tending normally to cause motor rotation, and thereby door movement, at a predetermined speed.

Abstract: A pallet construction for use with detachable tiering frames, which pallet is fabricated of metal having parallel stringers with a plurality of longitudinally spaced-apart deck members extending transversely therebetween which latter are fixed, as by welding, to said stringers. Said pallet may be adapted for use with tiering frames of the center post or corner post type by means of a unique support member fixed, in the former case, to the intermediate zone of the under face of the stringers and end deck members, and in the latter case to the ends of said stringers. Said supports each incorporate a surface bearing portion for engaging a portion of the underlying tiering frame; there being an adjacent inclined portion which serves as a detent to inhibit shifting of the pallet as so supported while also acting cammingly to assist in positioning of such pallet. Each support has a base portion for engaging a support surface.

A unique actuator system is provided for rotating the rotatable frame with respect to the support frame.

Abstract: A cartridge for both hunting and seed distributing purposes comprising a cylindrical casing having a primer, a propellant charge ignitable upon firing of said primer, spaced-apart wads above said propellant charge defining a load-receiving volume therebetween, a load of plant seeds received within a capsule disposed within said volume; a multi-missile shot charge provided above said volume and means for enclosing the normally forward end of said cartridge.

Abstract: A counterbalance for a window sash which comprises a bracket for securement to the window frame and which bracket contains spaced-apart slide plates with at least a pair of vertically spaced-apart transverse elements extending therebetween; there being a self-coiling spring suspended from each transverse member by means of the free end of such coil being lead over said transverse member. The free ends of said coil springs are connected to each other and then secured to a movable window sash for effectively counterbalancing same during movement between open and closed condition. Said transverse elements permit of at least two-point contact with said spring free ends whereby rocking of the spring coils is inhibited during sash counterbalancing operation.

Abstract: A materials handling device which comprises an upper load-receiving plate, a lower base plate in planar parallel relationship to said upper plate, said upper plate being of greater dimension than said lower plate and having a depending marginal flange, a pair of first and second lever units interengaging said upper and lower plates, said lever units being in spaced-apart planar parallel relationship and being pivotally interconnected intermediate their lengths. Each lever unit comprises an inner and outer arm adapted at one of their ends for movement linearly with respect to one of said plates. Fluid operated members are associated with each lever unit and are operatively interconnected therewith by means of a cam provided linkage. Said upper plate has mounted thereon a pair of swingable ramps.

Abstract: A flute piece consisting of a piece of tungsten carbide twisted or formed such that the flute piece has at least two helical cutting edges and an axis through which the tungsten carbide material extends. The flute piece is intended for an engineers' tool for working ferrous or non-ferrous metal, plastics or wood, such as a twist drill or a milling or boring cutter for a machine tool. A shank member has an extension web on one end thereof which is provided with a helical slot for reception of the flute piece.

Abstract: A label dispensing machine which is adapted to receive a supply of independent rolls of backing material each carrying readily detachable, adhesive coated labels thereon. A parting or discharge edge is provided for movement thereover of the backing strips to cause withdrawal of the strip from the supported labels for freeing of the latter.
