Abstract: A code generator produces one sequence of coded pulses having a predetermined code pattern. This sequence of coded pulses is transmitted to a remote point and received from the remote point to provide a replica of the sequence of coded pulses. A correlator is coupled to the generator and receiver responsive to the sequence and its replica to produce due to the predetermined code pattern an impulse output only when the sequence and its replica are time coincident and a zero output at all other time relationships between the sequence and its replica.

The feedback circuit includes a means to integrate the Q output signal of the flip flop.

Abstract: This relates to an apparatus for obtaining a specific antenna current or voltage waveshape at an antenna. A reference network, which includes a low level lumped element model of the antenna and the transmitter output network, produces drive signals when impulsed. The first of these signals corresponds to a voltage having the desired antenna current waveshape. The second is a voltage having a waveshape which must be produced across the input terminals of the transmitter output network in order that the specified antenna current be produced. The third signal is a voltage which has a waveshape equivalent to the waveshape of a current which must be injected into the input terminals of the transmitter output network in order that the specified waveshape be produced. At least one of these signals is used to drive the transmitter.

Small amounts of indium or gallium oxides can also be added to the mixture to lower the resistivity and temperature coefficient of resistance.

Abstract: A method and the apparatus to carry out the method produce an electric antiskid control signal for each braked wheel of a motor vehicle having an antiskid system. A reference value, approximating the vehicle speed, is produced from the output of the speed sensor of each braked wheel. The antiskid control signal for each braked wheel to correct the brake pressure therein is determined by the difference between the reference value and the momentary speed of the associated one of the braked wheels.

Abstract: A brake force distributor valve for limiting the brake pressure at the rear wheels of a vehicle when the load shifts to the front wheels during braking. The distributor valve includes a movable element which overcomes a spring to interrupt the flow to the rear wheel cylinders when the brake pressure exceeds a value determined by the preload on the spring. The spring abutment is fixed to the housing by shearing the surface of the material of one of the housing and abutment completely through at selected spaced locations about the periphery thereof and forcing the sheared material into a peripheral groove contained in the other of the housing and abutment while a predetermined force is applied to the spring to establish the spring preload and, hence, the response point of the valve.

Abstract: This invention relates to an apparatus for detecting the presence of a specific concentration of a conducting medium (water) in an insulating medium (oil) wherein the water/oil mixture forms an emulsion containing discrete droplets of water. A probe containing two electrodes, the first of which has a flat surface and the second of which is cone-shaped having a vertex directed at the flat surface, is immersed into the emulsion. A pulsating dc voltage is applied to the first electrode producing a static electrical charge which repels the insulating medium while having no effect on the conducting medium, causing droplets of the conducting medium to migrate towards and accumulate in the area between the electrodes. When a sufficient number of droplets have accumulated, a conductive path is formed between the electrodes causing an alarm to be generated.

Abstract: This relates to an ac circuit for actuating a monostable or bistable inductive device in response to the opening of a normally closed switch. A capacitor is provided in series with the parallel combination of an inductive switching element and a normally-closed switch. When the normally closed switch opens, there results a series circuit consisting of the inductive switching element and the capacitor which, when properly chosen, will have a capacitive reactance which substantially cancels the inductive reactance of the switching element, thereby substantially reducing the overall circuit impedance. This clearly reduces heat dissipation and insures sufficient voltage across the inductive element to cause actuation.

Abstract: A class of pseudo-noise multiplexed codes including coding mates having cooperating autocorrelation function which upon detection provides an impulse autocorrelation function. The code mates include at least one blank digit slot in the repetitious period of at least one of the codes of the code mates. One form requires a digit of either binary condition in the first and last digit slot of the code structure with the blank slot being disposed therebetween. The number of code mates can be increased by repeatedly solving the equations of FIG. 5 for the original code mates and the resultant new code mates. The interleaving process required in the equations is achieved by logic circuitry controlled by a control signal having a period equal to the period of a digit slot of the input code mates.

Abstract: Apparatus for degreasing and electroplating wire with a high current density electrolyte at high speeds includes a supply reel, guide pulleys, driving drums, degreasing and washing tanks, plating tanks and a take-up reel. The speeds of the driving drums for plating and degreasing are related and controlled in accordance with wire tension by means of a pulley, spring-based pivotable dancer arm, and a variable resistor. Fluid drag by wires running in one direction is eliminated by placement of a plurality of closely spaced anodes across the top of the plating bath and a flow stabilizer plate over the degreasing tank. A control circuit provides a desired constant ratio between drive speed and plating current.

Abstract: The correlator disclosed herein detects in a stream of input pulses a plurality of sequences of time spaced signals, each of the plurality of sequences having a different one of a plurality of pulse repetition intervals disposed within a given pulse repetition interval range. This is accomplished by clocking the input pulses into a first shift register by a first clock pulse having a given frequency. N groups of n bistable stages (N being an integer greater than one and n being an integer greater than zero) are disposed at different spaced time positions along the first register corresponding to the pulse repetition intervals and the pulse repetition interval range. First logic circuitry is coupled to each of the N groups of n stages to provide an output pulse when the time spaced pulses of the plurality of sequences of time spaced pulses are simultaneously present at appropriate ones of the n stages of a given number of the N groups of n stages.

Abstract: The disclosed synchronizing circuit employs flip-flops to synchronize a data signal to a clock pulse. The two flip-flops are controlled by the clock pulse and a delayed data signal to at least one of the flip-flops, the other flip-flop also being controlled by a delayed data signal or the data signal directly. A temporizing circuit receives the clock pulse and the output signal of one flip-flop and delivers a signal having a variable time delay according to the phase conditions between the data signal and the clock pulse. An AND gate or an appropriately connected JK flip-flop receives the output signal of the other flip-flop and the output signal of the temporizing circuit to provide the desired synchronized output pulse. This synchronizing circuit protects against the flip-flops synchronizing in an unstable state due to the critical period of the sampling edge of the clock pulse.
