Abstract: ABSTRACT OF THE DISCLOSURE           A plurality of relatively large, high capacity, high head, pumps disposed in parallel in the basement of a building provide water under pressure throughout the water pipes in a high rise building.  Pressurestatic switch means controls the operation of these main pumps.  A small, low capacity, high head auxiliary pump of an auxiliary booster system in the upper regions of the building supplies water to an accumulator tank in the auxiliary system from the water pipes so that during periods of low demand, such as at night and on weekends, the operation of the main pumps will be minimized.  A control assembly including a timer and pressurestatic limit switches in the auxiliary control system dictates when the auxiliary pump is actuated and shut off and when the accumulator tank is opened to the water pipes.

Abstract: DRIVE CIRCUIT FOR PARALLEL NON-MATCHED SEMICONDUCTORS       Abstract of the Invention This invention relates to a drive circuit coupled to electrical devices, which may be semiconductors, connected in parallel in a circuit network.  The electrical devices have distinct total on-time periods when they are simultaneously energized.  The circuit network has a source of power coupled through the parallel connected devices to a load.  The drive circuit includes a signal source coupled respectively through a time adjustable circuit to a first electrical device and to a second electrical device.  The time adjustable circuit is adjusted such that the total on-time of the first electrical device matches the total on-time of the second electrical device to thereby ensure equal power at all times through the electrical devices to the load.  The invention allows a number of parallel devices to act as a single switch.

Abstract: ELECTRIC FUSE FOR ELEVATED CIRCUIT VOLTAGES     Abstract of Disclosure A fuse for elevated circuit voltages having a blown fuse indicator. The fuse is characterized by its great simplicity of design.  Virtually all its components, or constituent parts, form a sub-assembly capable of being inserted as a unit into the fuse tube or casing.  One terminal of the fuse is formed by a plug contact that defines a heating chamber for heating one end of the restraining wire for the blown fuse indicator above all other points thereof.  The other terminal of the fuse is formed by a ferrule, or terminal cap, conductively connected to a perforated metal disk, or metal plate, arranged immediately adjacent thereto.  That disk or plate performs three functions, namely (1) to help support insulating rods around which the fusible element is helically wound, (2) to form one of the terminals of the fusible element and the restraining wire for the blown fuse indicator, and (3) to provide a large aperture through which the fuse is easily filled with arc-quenching filler.

A device is described for the interrogation and correction of a data signal which adopts a finite number of discrete signal values in a consecutive series of data cells. The transitions between the signal values exhibit a nominal minimum spacing. The signal is periodically interrogated with a period which amounts to at the most half of said minimum spacing. If a finite series of successive interrogation values exhibits a permissible pattern, the data value is directly derived therefrom (36), There is a set of further patterns which are not permissible, but which do not deviate excessively from a permissible pattern; the associated data value of the corresponding permissible pattern is then simulated. In the other cases an error signal (34) is formed. The pattern has a length which exceeds the length of a data cell. The inherent redundance of the data signal is thus partly used for the correction of errors,

Abstract: COBALT SILICIDE METALLIZATION FOR     SEMICONDUCTOR TRANSISTORS            Abstract of the Disclosure In order to form MOSFET structures, a cobalt layer is deposited and sintered, at about 400°C to 500°C, on a patterned semiconductor wafer having exposed polycrystalline or moncrystalline silicon portions, as well as exposed oxide portions.  The cobalt reacts with exposed surfaces of the silicon portions and forms thereat such compounds as cobalt monosilicide or di-cobalt silicide (CO2Si), or a mixture of both.  The unreacted cobalt is selectively removed, as by selective etching in a suitable acid bath.  A heat treatment at about 700°C or more, preferably in an oxidizing ambient which contains typically about 2 percent oxygen, converts the cobalt compound(s) into relatively stable cobalt disilicide (CoSi2).          Subsequently, deposition of an in situ doped layer of polycrystalline silicon (polysilicon) on the cobalt disilicide contacting the monocrystalline silicon portions -- followed by gettering, deposition of a layer of aluminum, and standard etch-patterning of the aluminum and polysilicon layers -- completes the metallization of the desired MOSFET structures on the silicon wafer.

Abstract: -14-               RCA 77,258 ABSTRACT OF THE DISCLOSURE Input video signals are applied to a video signal processor via an AC coupling capacitor and an input impedance.  A gated control circuit operates periodically to develop a DC control voltage for establishing the DC black reference level of the video signal, at which time the control circuit forms a feedback loop with the video processor.  The DC feedback control voltage is coupled via a feedback impedance to the AC coupling capacitor, which stores the control voltage, at the video processor input. The AC coupling capacitor exhibits a low impedance at signal frequencies, such that the input and feedback impedances form a voltage divider for sufficiently reducing the AC signal gain of the feedback loop to prevent the feedback control loop from oscillating at AC signal frequencies.

Abstract: ROLLER MILL CONSTRUCTION Abstract of the Disclosure An improved roller mill construction.  Material to be milled or ground such is fed through a discharge opening in a hopper to a pair of cooperating rolls that are mounted within a housing.  The discharge opening is enclosed by a sliding gate which is biased to the closed position and can be opened by manual operation of a pull rod.  An adjustable setting mechanism is incorporated with the pull rod and enables the gate to be held at an infinite number of open positions.  To adjust the spacing between the rolls, the shaft of one of the rolls is journalled within bearing assemblies that are mounted for sliding movement with respect to the housing.  A rod is secured to each slidable bearing assembly and is threadedly connected to a shaft which carries a sprocket.  By driving the sprockets in unison, the shafts will be rotated to thereby move the bearing assemblies and adjust the spacing between the rolls.  The movable roll is mounted for yieldable movement away from the fixed roll by compression springs which are located around the shafts and bear  between an abutment on the shaft and the housing.  Adjustment of the spacing between the rolls can be accomplished without changing the spring tension.
