Title: Engine idle stabilization timing circuit
Inventor: STAERZL RICHARD E
IPC: F02P5/155
Filed: 1987-05-21
Granted: 1992-09-22
Abstract: Abstract A timing circuit is provided for stabilizing idling of an internal combustion engine, particularly marine racing applications where idle speed must be reduced to enable gear engagement, notwithstanding the use of a racing cam otherwise requiring higher idlinq speed.  Delay means     provides a radical reduction in spark timing along a negative slope    relative to a baseline curve     up to a predetermined speed such as 900 rpm at which there is maximum relative timing delay .  As speed increases in this range, there is more retard because of the negative slope, which further retarded timing slows engine speed, hence providing self-stabilization.  As engine speed decreases in such range, there is less retard, and the advanced timing increases engine speed, again providing self-stabilization,  At engine speed increases above the predetermined speed such as 900 rpm, there is a rapid advance in timing along a steeper positive slope to merge with the baseline curve    .  Cranking and warm-up control circuitry      and acceleration detec-tion circuitry  are also provided for eliminating or reducing the relative timing delay under conditions where maximum spark advance is desired.

Abstract: Abstract of the Disclosure A process of separation of hafnium from zirconium by molten salt eletrolysis in which zirconium tetrachloride with ordinary hafnium tetrachloride content is dissolved in a molten salt and the zirconium tetrachloride is electrolytically reduced to zirconium trichloride with lower hafnium content at a cathode in the molten salt and hafnium tetrachloride is remained. Next, the cathode on which the zirconium trichloride is formed by the cathode reaction is used as an anode. The electrolytic reduction of zirconium tetrachloride at another cathode in the molten salt is carried out and at the same time the zirconium trichloride formed on the anode is oxidized to zirconium tetrachloride with a low hafnium content and the zirconium tetrachloride is evaporated for separation. The obtained zirconium tetrachloride containing a low hafnium content is suitable for production of reactor grade zirconium containing about 100ppm of hafnium.

Title: Automobile hauling trailer
Inventor: WESTERDALE NORMAN R
IPC: B60P3/08
Filed: 1988-07-26
Granted: 1992-03-31
Abstract: Abstract of the Disclosure The  invention  is  a trailer  for  carrying assembled automobiles, designed to be towed on the highway by a conventional motorized truck-tractor unit.          The  trailer  is  equipped  with  hoisting  points  to facilitate lifting and transporting the trailer unit from above by cargo container handling cranes, such as those found at shipyards and railyards.   In addition, the trailer is equipped with hydraulic valves  and hydraulic cylinders which serve to control the position of numerous tracks within the body of the trailer.          These tracks accommodate the tires of the automobile cargo carried within the trailer.  By adjustment of the hydraulic cylinders supporting the multiple tracks, the internal storage configuration of the trailer can be varied, to accommodate a wide variety of makes, models and numbers of automobiles,  and to ensure that  said automobiles are carried in a suitable position for safe transport.  The trailer body is designed to accommodate the fittings and fixtures on most commonly used flattop railroad cars,  and also features   three in-line; road wheels on each side of the trailer body,  and three separate axles supporting each pair of wheels disposed on opposite sides of the trailer.  The additional space created between the opening between the wheels  on opposite ends of the same axle allows the trailer to accommodate one additional vehicle within the body of the trailer,  while still providing sufficient tire surface to satisfy the highway load requirements of most states.  As an additional feature, the hinged top of the trailer, which opens to accommodate the loading process, is connected to the rear tailgate and side doors of the trailer with a series of mechanical interlocks, ensuring that when the trailer top and rear door of the trailer are closed and locked,   the side doors of the trailer are likewise closed and locked.

Abstract: A b s t r a c t Process for melting scrap iron, sponge iron and/or solid pig iron or the like.    For the purpose of melting scrap iron, pelletized sponge iron in reduced condition, solid pig iron or the like, it is proposed to introduced the melting heat from below by means of burners and to adjust a corresponding carbon content within the molten bath by a sub-stoichiometric combustion of hydro-carbon and thereby to renounce any addition of coal to the charged material. By reducing the oxygen flow, in particular by performing the combustion with approximately 0.9-times of the stoichiometric amount of oxygen, and by optionally adding slag formers, the aggressivity of the slag is simultaneously reduced.

Abstract: MANUFACTURE OF PLASTIC JACKETED STEEL PIPE Making jacketed pipe using metal strip coated with a plastic coating compatible with the jacket material. After the strip is formed into tube by turning over longitudinal edges of the strip, the jacketing material is then extruded onto the tube under an extrusion pressure insufficient to cause tube collapse. This is conveniently done by the known "tubing" process. Subsequent to the extrusion step, the jacket material is subjected to radial inward pressure also insufficient to cause tube collapse. This pressure reduces the outside diameter of the jacket and presses it against the coating on the tube. The inward pressure step is performed while residual heat from extrusion remains at the inner surface of the jacket to fuse the jacket to the plastic coating. Inward pressure is preferably applied by a polishing die.

Title: Brake for a vertical dynamoelectric machine

Granted: 1992-03-31
Abstract: BRAKE FOR A VERTICAL DYNAMOELECTRIC MACHINE            ABSTRACT OF THE DISCLOSURE          A braking arrangement for a vertical axis dynamoelectric machine has a braking ring mounted to the rotor and the braking ring has a downwardly facing braking surface.  A plurality of brakes are spaced around the machine beneath the braking ring.  Each brake has a brake cylinder with a piston and an upwardly projecting piston rod.  The upper end of the piston rod is fastened to a brake plate which supports a brake pad.  The disc-like portion of the piston has a peripheral edge wall that has a crowned configuration to permit tilting of the piston rod thereby reducing the tendency for jamming under large side loads.  There is a seal in this peripheral edge wall which contacts the cylinder wall.  The top closure of the brake cylinder, through which the piston rod extends, has an opening for the rod that is larger than the diameter of the rod to permit the tilting of the piston.  A washer-like seal within the cylinder around the rod seals the space between rod and top closure.  The end of the piston rod also has a crowned configuration which bears against the brake plate.  A bolt in a recess in the brake plate extends through the plate and fastens in the end of the piston rod, and there is a conical washer beneath the bolt.  The crowned end of the rod and the conical washer permit the brake plate and pad to tilt with respect to the rod thereby compensating for misalignment as a consequence of side loading or uneven brake wear.
