Abstract: An automatic, hydraulically-operated steering assembly for a towed vehicle is disclosed. Each set of steerable ground-engaging wheels of this towed vehicle is steered by a double action piston fed by a pair of hydraulic hoses connected to a control valve actuated by a pivotal device and a control rod. A bypass is provided between the two hydraulic hoses to allow the hydraulic pressure to slowly equilibrate in the two hoses and thus allow the wheels to return in their straight line position when the source of pressurized fluid is normally disengaged or in the case of a failure of the hydraulic system. Advantageously, the valve is controlled by a push-pull cable having one end attached to one wheel and another end to the valve. The towed vehicle may comprise one or more sets of steerable wheels. In the latter case, the front and rear sets of wheels are adapted to pivot in either direction, the middle set being non-pivotal.

Abstract: A gate array architecture is disclosed that utilizes significantly less silicon area than the prior art. The core cell (100) includes a four transistor arrangement in which a substrate tap (308) is located adjacent to the transistor pair. This provides for a more "symmetric" cell array than those in the prior art. Through the placement of the taps (304, 308, 314) outside of the transistors the power line connections can be routed in a simple and efficient manner. In addition the gate array architecture mirrors pairs of transistor columns (302, 306, 310, 312) for the sharing of substrate taps (308) between pairs of columns. This mirroring feature further reduces routing complexity.

Abstract: A control system utilizing a programmable controller for an injection molding machine  in which the controller is periodically scanned in response to input signals to produce output control signals is provided with an impulse response filter arrangement.   The impulse response filter senses a plurality of current and past sensor input signals to accu-rately predict the occurrence of a variable triggering event which will in fact be sensed by a sensor.  A predictive sensor signal is then generated which is inputted to the controller in advance of the occurrence of the triggering event and at a time which corresponds to the processor scan time so that the controller generates the desired output at the precise time the  triggering  event  occurs  thus  eliminating  controller response latency from the control system.

Abstract: A service provider for use in a client-server system which is capable of detecting the abnormal termination of a client process is disclosed. The service provider does not require a dedicated process for polling client processes in order to verify their status. Rather, a semaphore, which is used in conjunction with a shared memory segment for communication between a client process and the service provider, is initialized in such a manner that the operating system will automatically increment the semaphore in the event the client process is terminated. Thus, the semaphore will be incremented either when the client process deliberately increments the semaphore in order to notify the service provider that the client process has written data to a shared memory segment, or the semaphore will be incremented by the operating system in the event the client process terminates. A test flag is established in shared memory in order to differentiate whether the semaphore was incremented by the client process, or by the operating system. The client process will set the flag only when the client process increments the semaphore. Therefore, whenever the semaphore is incremented, the service provider will test the condition of the flag, and terminate resources allocated to the client process if the flag is not set.
