Abstract: There is disclosed a dual-circuit brake-force distributor wherein the control force of one circuit is transmitted to the other circuit through a floating intermediate piston. In order to achieve a highly sensitive control, the intermediate piston is provided with a large cross-sectional area. In the event of failure of the one circuit, the intermediate piston will become blocked and the control force will be transmitted through an auxiliary piston having a smaller cross-sectional area. By this arrangement upon failure of the one circuit a sufficient amount of braking pressure can still build up in the other intact braking circuit.

Abstract: An automatic locking system is provided for securing a submersible pump to vertical guide wires. The pump is automatically locked to the wires upon lowering of the pump and released upon raising the pump. Stationary cams in the pumping station actuate the locking system. The system assures locking when the pump is lowered and eliminates the need for manual unlocking by the serviceman when raised.

Abstract: There is provided a brake-force distributor, wherein the normally controlled rear-axle brake circuit is no longer influenced by the distributor if the front-axle brake circuit has failed. This is achieved by arranging the valve seat at a sleeve held in the operating position by the front-axle brake pressure. In the event of failure of the front-axle brake circuit, the rear-axle braking pressure will displace the sleeve into a position in which the distributor is not allowed to close.

The pulse train can be used for generating a variable dc voltage particularly for the tuning voltage of TV receiver capacitance diodes.

Abstract: An improved electrified channel where the channel has four leads, one of which acts as a middle or neutral wire, while the remaining three leads act as phases of three distinct electric circuits. Two contactors are associated with the related connector, such as a stationery contactor acting as neutral, and a movable contactor for the selection of the three phases.

Abstract: An improved bearing bracket is provided for a submersible close-coupled motor and pump wherein the bearing bracket supports an outer non-rotating ring of a ball bearing that rotatably supports the motor shaft at a location between the motor and pump. The bearing bracket sealingly supports two concentric non-rotating seal elements that engage a radially extending flange mounted on the end of the motor shaft to provide a seal between the pump and the motor housings. The space between the seal elements is connected to a reservoir for supplying a lubricating and cooling medium for the seal elements.

Abstract: The radar has two antennas which radiate RF signals of different frequencies and whose radiation patterns overlap. The frequencies of the radiated signals are generated by amplitude-modulating a single RF signal with two low frequency signals. The signals received by one of the two antennas are evaluated by determining, in an evaluating device, the difference between the amplitudes of the RF signals of different frequency which are reflected from an object. A DC voltage signal proportional to the above difference is generated and the DC voltage signal is fed to a threshold circuit whose threshold is determined by a predetermined azimuth range. Therefore, it can be determined if the reflecting object is in the same road lane as a car equipped with the radar.

Abstract: A constant dc voltage source is connected to the non-inverting input of a differential amplifier with a negative load resistance. The output of the differential amplifier is coupled directly to the inverting input and to a filter circuit for providing a filtered dc signal, the amplitude of which is controlled by a pulse train of variable pulse duty factor connected to the input of an electronic switch which, in response to the pulses, switches the input of the filter circuit between the constant dc voltage and a reference potential.

Abstract: An integrated clock pulse shaper showing a pair of resistivities each of which is connected in series to ground over the source drain line of one of a pair of MISFETs. The MISFETs are galvanically cross-coupled from the drain to the gate. A pair of overlapping pulse trains each of which is fed to one of the pair of resistivities, are shaped to a non-overlapping pair of pulse trains occurring at the common connection points of each transistor/resistivity pair.

Abstract: A monolithic integrated circuit for an RC oscillator includes a differential amplifier acting as a switching stage for comparing a threshold voltage corresponding to the maximum oscillator voltage with the capacitor voltage of the RC circuit. An output of the differential amplifier is connected to the S input of an R-S flip-flop which is set when the capacitor voltage reaches the threshold voltage. A switching transistor has its collector and emitter connected across the capacitor and a base connected to the output of the R-S flip-flop for discharging the capacitor when the flip-flop is set.

One of two emitters is connected to the base of the double emitter transistor. The junction area of this emitter is many times greater than that of the other emitter.

Abstract: A pressure responsive valve for distributing the fluid under pressure delivered by a fluid pressure source to two user components, one of which is connected to an accumulator. The device includes a control valve which is disposed in a line connecting the fluid pressure source with a first user component and governs the cross-section of the passage in that line. The control valve has a control chamber and cross-section reducing member when the control chamber is in communication with the fluid pressure source. When the control chamber communicates with the return line the cross-sectional area of the passage increases. In addition a pilot and/or stop valve is included which changes its position depending upon the pressure existing in the line connecting the fluid pressure source with the second user component.

Abstract: Aluminum films on a semiconductor surface are etched in a carbon tetrachloride glow discharge. Typical etch rates are 2000-3000 A/min. The addition of 15% ammonia to the plasma prevents HCl formation when the etched material is exposed to air.This process provides a more easily controlled process for the manufacture of high density integrated circuits.

Abstract: At least two juxtaposed brake rings forming a brake disc for disc brakes are carried by a cup-shaped hub and connected with one another by the hub. Each of the two members have the same basic form and are fitted into one another. Each of the members integrally forms a brake ring and hub members which are connected with one another by a fastening device for securing the multi-part brake disc to a carrier.

Abstract: A pressure control arrangement for hydraulic brake systems including a plunger piston which is sealingly slidable with a bore and which defines a chamber connecting with at least one brake cylinder. The chamber is connected with a brake pressure source through a valve which is kept in the open position by a connection to an auxiliary pressure source which prevents the valve from reaching or maintaining its closing position when the auxiliary pressure has failed. The auxiliary pressure is controllable for effecting an anti-skid control for which purpose the auxiliary pressure source is connected with a control chamber which is opposite the valve chamber connected to at least one wheel brake cylinder through at least one auxiliary valve.

Abstract: A braking system provides for a master cylinder of the tandem or split type connected through a control pressure device to the wheel cylinders of brakes for at least one of the wheels which includes a modulating valve controlled by the master cylinder pressure which provides an auxiliary pressure obtained from a source of brake fluid under pressure. The modulating valve feeds through a control valve which is under the control of an electronic anti-skid device. Thus, the modulating valve controlled by the master cylinder's pressure through the control valve effects the operation of the pressure control valve and applies the brakes of the vehicle.
