  • Patent number: 4973035
    Abstract: A device for stacking and compacting photographic prints, and inserting stacks of prints into envelopes, includes a selector for directing individual prints along separate paths, according to their characterisitcs, toward a multiple stacking chamber at the end of the print paths, where the prints are formed into separate stacks. A compactor for compacting then compresses the stacks against a portion of the stacking chamber, and a pusher ejects the packs from the compactor in a direction orthogonal to the direction in which they entered.

  • Patent number: 4957680
    Abstract: The seal ring is molded by positioning a frame or reinforcement in one part of an opened mold, and positioning a low friction material disc on a clamping surface of the same part of the mold. The mold is closed with a second part so that between 30% and 70% of the disc is clamped and squeezed between opposed surfaces of the mold parts, and the reinforcement or frame is held in position in the closed mold. A vacuum is drawn in the mold, and an elastomer is injected to form a body or lip connecting the reinforcement to the disc. The molded ring is removed from the mold and excess lip material and at least the portion of the disc which was clamped are cut off to form the finished seal ring. The low friction material disc can contain PTFE.

  • Patent number: 4951413
    Abstract: A troll line depressor includes a pair of triangular wings with a dihedral angle of about 100 degrees therebetween. A rigid bridle connected between the upper and lower ends of the depressor provides a sliding connection for a ring at the end of a towing line, so that the depressor normally develops hydrodynanmic forces to depress the end of the towing line, but can tilt backward to an inoperative position when a fish strikes, or forward to an inoperative position if the depressor engages river bottom debris.

  • Patent number: 4938395
    Abstract: A mouthpiece is designed to facilitate direct human consumption of liquid from a narrow-necked container, such as a bottle having a mouth defined by a peripheral rim that in use is enclosed by the lips of the consumer. The mouthpiece comprises a tubular body that engages the peripheral rim of the bottle mouth and forms an annular seal therewith and an adjoining extension that defines an annular wall projecting axially to surround the container adjacent its mouth. Vent passages in the mouthpiece communicate between an interior outlet receiving a tube for opening to the interior of the container, and an exterior inlet located on the surface of the mouthpiece at a position spaced from said free end by a distance sufficient to ensure that in use the inlet will not be blocked by the lips of the consumer and air can pass therethrough to the interior of the container to replace the liquid being consumed.

  • Patent number: 4935673
    Abstract: A parallel RC network sensitive to the impedance of a gas discharge device is provided in the electronic ballast of this device along with a series connected inductive coil. As the impedance through the device changes, the oscillator frequency of the ballast would change accordingly and the voltage through the coil would change, thereby changing the impedance in such a manner as to insure that the voltage through the gas discharge device remains unchanged. The ballast would include a switch-mode, push-pull oscillator including a pair of emitter-resistors and a pair of fast diodes.

  • Patent number: 4921605
    Abstract: An apparatus to clean or depollute surfaces or layers of water. The apparatus has at least one channel (12) which withdraws a stream of water at the front of the apparatus and discharges the water at the rear of the apparatus after cleaning or depollution. The water can be discharged through two conduits or tunnels (18), which diverge relative to each other. The flow of the stream of water through the channel (12) is caused by at least one propellor (20) driven by a motor which can be hydraulic.

  • Patent number: 4919425
    Abstract: A training and shooting aid for basketball players to eliminate and prevent interference by the guide arm and guide hand when shooting a basketball. The training and shooting aid includes a pair of adjustable interconnected stretchable sleeves adapted to encircle a player's guide arm. One of the sleeves is intended to be snugly secured around the player's arm slightly above the elbow, while the other of the sleeves is intended to be snugly secured around the player's arm slightly below the elbow. A non-stretchable separable strap member has a free end adapted to be associated with one of the band members. The opposite end of the strap member is provided with a loop for placing around the thumb of the player's guide hand. Once the loop has been placed around the player's thumb, the strap member is adapted to be tightened, whereby the guide hand and thumb are pulled toward the elbow.

  • Patent number: 4903506
    Abstract: In a commercial ice cube making device, an accelerated freezing and harvest cycle is effected by employing parallel adjacent rectangular channel ways which are individually directly connected to intake and outflow manifolds, thereby producing even absorption and dispersion. In addition, melting of the cubes during the short harvest cycle takes place on one side only thereby reducing the problem of stored ice cubes freezing and sticking together. The ice cubes are made in novel nylon ice trays with combed partitions which allow ice to form from the vertically disposed evaporator outwards on both of its sides. The device advantageously produces large quantities of symmetrical non-sticky ice cubes more quickly and efficiently than the devices known in the prior art.

  • Patent number: RE33526
    Abstract: A control system for power tongs comprises two tongs torque limiters, one of which limits tongs torque to a very low (hand-tight) level; the other limits torque at full makeup to, for example, 2000 ft. lb. The hand-tight torque limiter is manually or automatically disabled after the hand-tight level is reached. The system enables the operator to verify that the threads are properly engaged before applying full torque to the connection. The tongs have a very high reduction ratio, so that torque rises very slowly and can be more accurately controlled.
