Abstract: RANGE COUNT AND MAIN MEMORY ADDRESS ACCOUNTING SYSTEM              ABSTRACT OF THE DISCLOSURE    In a peripheral controller of a data processing system having a plurality of system units electrically coupled to a common communication bus for asynchronous intercommunication, an array of counters responsive to both hardware and firmware are connected in a manner to form a serial control data path.          Prior to a data transfer, a serial data stream including an offset range count, a range count and a main memory address is shifted through the counters under firmware control.  During a data transfer, the firmware enables the hardware control to increment the memory address and decrement the range count to accommodate the higher data transfer rates characteristic of hardware control.

Title: Static inverter and a transformer for  use in a static inverter
Inventor: SCHMITZ NICHOLAS A
IPC: H01F38/00
Filed: 1979-03-02
Granted: 1982-12-28
Abstract: ABSTRACT OF THE DISCLOSURE: A static inverter and a transformer for use in a static inverter are disclosed. The inverter comprises one or two switching semiconductor devices and a novel power transformer having a primary winding and first and second control windings associated with a linear magnetic core. A pair of serially arranged apertures partition the core into five localized branches. The second control winding is coupled via a central branch lying between the apertures, to the first control winding. At the initial part of each switching cycle, regenerative control action is provided to the associated switching device by the first control winding. As the cycle progresses, a pair of branches saturate, reducing the regenerative control action, and diverting the main flux through the central branch in a sense reversed to that provided by the first control winding. When the main flux is coupled to the second control winding, degenerative control action results, completing the turn off of the semiconductor device. The five branch arrange-ment provides a carefully matched control voltage to the associated semi-conductor devices, improving the life and reliability of the devices and enhancing the efficiency of the inverter.

Abstract: ABSTRACT         A circuit for generating a percussion envelope for use in electronic organs and similar electronic keyboard instruments wherein the envelope has an attack overshoot, a long decay, and a snub decay when the key is released.  A velocity sensing feature is included, whereby the force with which the key is struck determines the amount of capacitor discharge, and the voltage remaining on the capacitor is compared with the amplitude of the attack portion of the envelope such that decay is initiated when a compare condition is reached.   A second comparator sets the amplitude at which the envelope undergoes transition from a fast decay to the normal long decay.  The timing for the attack and three decay portions of the envelope are independently con-trolled by means of four clock driven electronic gate circuits which incrementally charge and discharge the main timing capacitor.  The gate circuits include a pair of serially connected field effect transistors having a capacitor connected at their juncture.  The timing control for each individual keyer, including all of the timing capacitors, is contained within a separate LSI chip.

Abstract: ABSTRACT OF THE DISCLOSURE        The invention relates to a solar energy conversion apparatus in which several evacuated, glass tubular collectors are connected together in a liquid circulation system for controlled move-ment of a liquid between the interior of the collectors and a storage tank.  Liquid circulation is controlled by sensors and switches therefor in regulating operation of valves and/or a pump.  The conditions for circulating the liquid rely upon (1) sensing a need for energy at the storage tank, (2) sensing solar radiation availability, (3) sensing thermal conditions in the solar collector tubes to avoid high temperature and thermal shock, and sensing a need to withdraw hot liquid and add more.  The system is operable in either of two modes herein disclosed:  (a) the "continuous batch circulation" mode in which liquid is pumped to fill the tubes, in parallel, and low temperature sensed below a set point to stop pumping and resume pumping when the temperature in the tubes arrives at the preselected higher temperature, and (b) the "full continuous circulation" mode in which liquid is continuously pumped through the tube collectors, in parallel, continuously withdrawing liquid from the top of the tube while introducing liquid at the bottom of the tube; in either mode, the hotter liquid being removed from the top of the tubes and relatively colder liquid introduced at the bottom of the tubes.

Abstract: Abstract of the Disclosure A counterbalance valve assembly for use in a hydraulic system of the type including a hydraulic cylinder for raising and lowering a load provides gradual and con-tinuous exhaustion of hydraulic fluid from the cylin-der to facilitate smooth lowering of the load.  The assembly includes a counterbalance valve having an outer barrel and an inner barrel forming an annular channel therebetween through which the exhausted fluid passes.  The outer barrel includes an inner valve seat and the inner barrel includes an outer re-lief valve surface which engages in the annular chan-nel to form a relief valve.  The inner barrel is movable in a linear direction within the outer barrel for opening and closing the relief valve as the load is lowered.  To avoid abrupt changes in the exhausted cylinder fluid flow rate, and thus to avoid abrupt variations in the load lowering rate, the relief valve surface has a long tapered configuration rendering the exhausted fluid flow rate less sensitive to inner barrel movement.  Additionally, the inner barrel in-cludes a flange of slightly less dimension than the inner diameter dimension of the outer barrel re-sulting in an annular space therebetween.  Fluid is therefore allowed to fill an outer barrel chamber opposite the inner barrel forming a dashpot means for dampening inner barrel movement.  As a result, the long tapered relief valve surface and the valve dashpot are operative individually and collectively to avoid abrupt closure of the relif valve for pro-viding gradual and continuous exhaustion of the cylin-der fluid and thus gradual and continuous lowering of the load
