Abstract: RIGID PAPERBOARD CONTAINER AND METHOD  AND APPARATUS FOR PRODUCING THE SAME                          ABSTRACT    A pressed paperboard container (10) is formed having a bottom wall (11), an upturned side wall (12), and an over-turned rim (13) extending from the side wall which is denser and thinner than the rest of the container.  The container is formed by pressing a flat circular blank (27) between upper and lower dies (25, 26) having die surfaces (31, 32, 38, 39, 40) which shape the blank into proper form, and the surfaces of the dies (25, 26) at the rim area (13) of the container are shaped to exert extremely high compressive stresses on the rim, particularly at the folded areas (20) formed in the rim during initial shaping of the container.  The high compressive stresses applied to the rim area, along with proper moisture levels maintained in the paperboard and the heating of the paperboard by the heated dies, causes the paperboard in the rim area to deform plastically, densify, and fill in voids created as the blank was pressed into the container form.  The integral, dense rim is a rigid structure which provides resistance to bending to the entire container.

Abstract: ENERGIZATION INDICATION CONTROL      FOR DIESEL GLOW PLUG     Abstract of the Disclosure An indicating lamp and a PTC thermistor are connected in series across an electric power source by an ignition switch which simultaneously actuates apparatus to intermittently energize a diesel engine glow plug.  Further apparatus is effective to make and break a low resistance shunt path around the indicating lamp in response to deenergization and energization of the glow plug. The indicating lamp and PTC thermistor both are electrically energized to self heat and both have electrical resistances increasing sufficiently with temperature to drop substantially most of the supply voltage when hot and prevent energization of the cold other.  The indicating lamp heats much faster than the PTC thermistor and so energizes during the initial energization of the glow plug to signal the vehicle operator to not attempt starting of the engine.  However, upon the first making of the low resistance shunt path, the PTC thermistor increases its resistance to drop sub-stantially most of the supply voltage and maintains this condition through further cycling to prevent further energization of the indicating lamp.

Abstract: TITLE A HYBRID INVERTER     INVENTOR Pradeep Bhagwat ABSTRACT OF THE DISCLOSURE The hybrid inverter consists of thyristor switches with their related commutation circuit, paralleled by transistor switches.  When the current magnitude is below a predetermined level, it is conducted by the transistor switches and when above the predetermined level, it is con-ducted by the thyristor switches.  The commutation circuit includes a capacitor which need not be precharged to initiate commutation.  Thus, the commutation circuit works only when a thyristor is conducting current thereby substantially reducing the number of commutations in an output cycle,

Abstract: Abstract An automatic kinescope bias (AKB) control system includes a sampling amplifier which provides an output current for charging and discharging a storage capacitor in response to the amplitude of a derived pulse representative of the black current level conducted by the kinescope of a television receiver.  The derived pulse amplitude is greater than zero when the black current level is correct, and is applied to the amplifier via an input signal coupling path.  During sampling intervals, an auxiliary pulse is applied to the input signal path with a magnitude and sense for negating the amplitude of the derived pulse at the amplifier input when the derived pulse amplitude corresponds to the correct black current level. Accordingly, the amplifier conduction and the voltage on the storage capacitor remain unchanged.

Granted: 1988-06-28
Abstract: "FOOT SNARE LIVE TRAP"     ABSTRACT OF THE DISCLOSURE             The trap is a modification of an existing trap which comprises:  a length of spring steel rod formed into two arms joined at their first ends by a coil spring, said arms being angularly dis-posed at about right angles when the coil is relaxed; a rotatable catch member, secured to the second end of the lower arm, for releaseably holding the upper arm in a cocked position, close to and parallel to the lower arm; a trigger for releasing the catch member when the trigger is stepped on, so that the upper arm will spring upwardly; and a chain securing the rod structure to an anchor, such as a tree.  In accordance with the modification, an eye is provided on the free end of the upper arm.  A cable is secured to the free end of the lower arm and extends through the eye, so as to be slidably connected with the end of the upper arm.  A slip noose is formed at the free end of the cable, which noose can be positioned to overlie the trigger.  When the catch member is released, the upper arm throws the noose upwardly and simultaneously tightens the loop onto the paw of the animal.  Because the cable remains attached to the two free ends of the now angularly disposed arms, and is free to slide through the eye, the jerking pulls of the snared animal on the end of the cable will merely cause the arms to be pulled part way together, against the resistance of the coil spring.  Thus the animal is not jerking on a cable attached to a rigid anchor, and thus will not injure itself.

Abstract: A differential pressure calibrating tank for sizing and cooling just-extruded duct having electrical cable extending through it includes a duct inlet opening and a calibrator head adjacent to that opening for sizing the just-extruded duct. Differential pressure across the walls of the duct tends to keep the duct in a round cross-sectional shape. Flexible conduit in the duct and fixed relative to an adjacent extrusion die but movable in the tank precludes contact between the duct and cable within it while the duct is still molten. The flexible conduit precludes sticking or adherence between the insulation of the electrical conductors and the duct inner walls. In addition, an improved means is provided for restraining the duct submersed in the water as it traverses through the differential pressure calibrating tank. The means for restraining the duct includes, in part, a perforated tube situated within the tank having an inverted V-shaped channel traversing the length of the tube. Buoyant forces acting on the duct in combination with the V shaped channel tend to keep the duct in a particularly desirable round cross-sectional configuration.
