Title: Terminating device for wire
Inventor: SONOBE TOSHIMITSU
IPC: H01R13/10
Filed: 1990-07-13
Abstract: ABSTRACT          TERMINATING DEVICE FOR WIRE:           A terminal for terminating wire comprises a contact portion for electrical connection to a conductor of the wire and a crimping portion for crimping to insulating material on the wire.  The crimping portion is formed to have an outwardly bulged barrel-like portion. The bulged portion provides a configuration that has a dimension greater than that of burrs which may be formed during fabrication of the terminal.  Thus, in use, for example, where the terminal is to be inserted through a water-seal bushing, damage resulting from sharp burrs may be minimized.

Title: Method and apparatus for detecting illegal pitches
Inventor: JOHNSON MARK P
IPC: A63B69/00
Filed: 1990-07-13
Abstract: METHOD AND APPARATUS FOR DETECTING ILLEGAL PITCHES       ABSTRACT       Methods of an apparatus for detecting pitches which are illegal in the game of slow pitch softball by virtue of their having exceeded a maximum allowable height of twelve feet in traveling form the pitcher's mound to home plate.  Infrared, visible, or ultraviolet light is reflected from a ball reaching a height above the permitted maximum to a detector which is incorporated in a unit typically mounted on the backstop at the appropriate height.  The light which is reflected may be natural light, or the light may be generated in and propagated from the backstop-mounted unit.  In both cases, the impingement of the reflected light on the detector causes that component to output an electrical signal which is amplified and employed to drive a sound generator, thereby providing an audible warning that an illegal pitch has been thrown.

Abstract: ABSTRACT            A logic controlled delay circuit is connected into the arbitration logic of a computer system of the type having a main data bus which is subject to control by multiple masters.  The  delay  is  so programmed that  the  default master, which is the main processor (CPU) for the system and  is  assigned  the  residual  or  default priority,  is assured a predefined portion of the time available on the bus. By so inserting and controlling the delay that the "hold" signal to the CPU is delayed whenever the CPU is granted access to the bus, other devices, are unable to seize the bus until the delay has ended at which time the CPU is triggered by the delayed signal to respond with an acknowledge which serves to permit arbitration to begin. By this technique a standard microprocessor such as an Intel 80386 can operate in such an architecture without being  preempted  from  the  bus  by the  higher  priority devices to an extent that system operation deteriorates.

Abstract: The present invention relates to a process for preparing a metal sheet having an excellent rolling property, i.e., a rollable metal sheet, which process comprises the basic steps of:  continuously feeding a molten metal on a cooling material having one or two cooling surfaces being transferred and renewed for quench solidification, to thereby prepare a thin cast sheet; impinging a small rigid body particle against the surface of the resultant thin cast sheet, to work the cast sheet; heat-annealing the worked sheet in such a manner that the worked region becomes a fine recrystal-lized grain layer; and subjecting the cast sheet to a cold or warm rolling, optionally after a removal of oxides present on the surface; and an optional step of heat-treating the rolled sheet for working.  The process of the present invention is applicable to the production of various known rollable metal or alloy sheets, such as soft steel, stainless steel, silicon steel, nickel-iron, cobalt-iron, nickel, aluminum, and copper sheets.

Abstract: L'invention    se    rapporte    à    plusieurs perfectionnements  apportés  aux motoneiges.   Un  premier perfectionnement  consiste  à  disposer  une  languette  en arrière des patins se trouvant en avant de la motoneige pour diriger  celle-ci,  de  façon  à  ce  que,  lorsque  la motoneige recule,  l'arrière des patins ne vienne pas se coîncer dans des branches.

Ce bras de levier qui a de préférence la forme d'un grand U peut être monté de façon repliable le long de la selle ou des appuie-pieds de la motoneige.    Il  peut  également  être monté de  façon permanente en position verticale le long du capot et du pare-brise.  Enfin, un troisième perfectionnement consiste en une toile pouvant être montée de façon amovible à même le capot avant de la motoneige et éventuellement le pare-brise  tout  en  laissant  le  phare  et  les  entrées  d'air libres,  pour  éviter que  les  branches  dans  le bois  ne viennent égratigner trop rapidement la motoneige.

Abstract: AIR BRAKE SYSTEM FOR AN ARTICULATED RAILROAD CAR    Abstract of the Disclosure A railroad air brake system for use on an articulated railroad car having a plurality of platforms and trucks support-ing the platforms, has separate air brake subsystems for the trucks supporting the end platforms and an intermediate platform.          The subsystem for the intermediate platform includes a control valve connected to the train air supply; an air actuating means for each truck supporting the intermediate platform; a sensor valve having a load sensing arm for each truck supporting the intermediate platform, which sensor valves are commonly connected in parallel to both air actuating means; a proportional valve having an input connected to the control valve and an output commonly connected to both air actuating means and both sensor valves; and a volume reservoir connected to the sensor valves and the proportional valve.  The application of brake pressure from the control valve to the proportional valve, with an empty load condition at either intermediate platform truck causes the sensor valve associated therewith to cause the proportional valve to reduce the air pressure supplied therefrom to the air actuating means for both trucks supporting the intermediate platform.
