Patent ES-406967-A1 (ES)
Title: Auxiliary power steering device for vehicles with pressure accumulators
IPC: B62D5/24
Filed: 1972-09-23
Abstract: The invention effects a short path readily sealed against leakage for pressure fluid supply to double acting hydraulic booster steering mechanisms of the type utilizing a piston internally threaded for coacting with an externally threaded steering spindle which extends into the piston and which spindle controls valving for selectively pressurizing either end of the cylinder. In installations where pressure accumulators are utilized for feeding the steering system and other devices on the vehicle, e.g., brakes, leakage in the high pressure system is serious because the size of accumulators are limited by space requirements and pumps for pressurizing accumulators are small. Hence, the invention minimizes such leakage by pressure feed through a tube passing into the piston from an end of the cylinder and communicating with a pressure feed bore in the steering spindle. Since the parts are small the sealing elements for such tube are correspondingly small and the leakage thereby reduced to a minimum.
Patent ES-426061-A1 (ES)
Title: Transmission controlled spring applied steering brakes
IPC: B60T15/18
Filed: 1974-04-07
Abstract: The vehicle is provided with a pair of spring applied brakes which are individually controllable through hydraulic actuators acting in opposition to the springs. The brakes are individually controlled by a valve associated with the hydraulic actuators and are automatically, simultaneously applied by operation of brake pressure regulating valves which are biased by the pressure of the hydraulic control system for the forward-reverse clutches of the vehicle transmission. The vehicle brakes are applied by balancing pressure across the piston of the brake actuator. During forward or reverse travel of the vehicle, the pressure on one side of the brake actuator compresses the spring to release the brakes. When low fluid pressure is supplied as when the engine is dead, the brake actuator pressure will drop thereby permitting the springs to apply the brakes. When the engine is running and the hydraulic systems are functioning normally, the brakes are applied by the springs whenever the pressure is balanced on opposite sides of the spring loaded brake actuator. The brake pressure regulator valves cause the pressure to be balanced at reservoir pressure when the biasing pressure from the change speed transmission control drops to a low level as when in neutral or during directional shifts.

Patent ES-429290-A1 (ES)
Title: Amplifier with failsafe predertermined gain
IPC: H03F1/34
Filed: 1974-08-14
Abstract: An amplifier in which the feedback impedance includes a four terminal capacitor, and in which the input impedance is connected to a source of operating potential. The use of a four terminal capacitor as a feedback element compensates for the failure mode of the amplifier in which the opening of the feedback element results in infinite AC gain of the amplifier. The connection of the signal input impedance to a source of operating potential compensates for the failure mode of the amplifier in which the input impedance shorts, which normally results in infinite AC gain of the amplifier.

Patent ES-436324-A1 (ES)
Title: Wrapping and sealing machine
IPC: B65B11/42
Filed: 1975-04-04
Abstract: A device for sealing wrapping material on pieces of candy or similar products, in what is known as the "soap" style of wrapping, and for exiting the products, in their sealed wraps, from the wrapping machine. Each wrapped product is first received in a correspondingly dimensioned pocket of a horizontal conveyor disk, which intermittently conveys the product along a sequence of plates, comprising a presser plate, a first heat-welding plate, and a first cooling plate. The presser plate eliminates bulges of the sides of the product, created during the wrapping. It presses other sides of the product, with folded tabs of the wrap thereon, into the pocket. The heat-welding plate then seals portions of the wrap on a then exposed side of the product. After the cooling and during one of the steps in the intermittent travel of the disk, the product enters a similarly dimensioned but differently arranged pocket of a vertical, intermittently movable conveyor disk, which by the next following steps in its intermittent travel conveys the product along a second set of heat welding and consecutive cooling plates, for sealing the folded tabs of the wrap on then exposed sides of the product. The vertical disk finally brings the product in its sealed wrap to an exiting station.

Title: Highly sensitive fault current protection switch responding to any current.
IPC: H02H3/33
Filed: 1981-02-26
Abstract: The invention relates to a high sensitivity fault current protection switch, responding to any current, which is used particularly in domestic electrical installation technology and consumer networks. The circuit is used for the detection of fault currents of any wave form and for the detection of low resistance connections between the neutral and protective earth lines in the load. In this case, a frequency generated by a clock generator (1) is fed to the secondary winding (3) of a summing current transformer (2), the output of which is connected to a voltage divider (6), by means of which the clock current is made symmetrical. The pulsed signal is passed to a comparator circuit (7, 8) via a winding tapping (4), the pulsed signal being compared with in each case one reference voltage. If the signal is too high and/or too low, the comparators (7) and/or (8) switch on, thus activating the trip relay (12). An RC element (10) with a downstream comparator (11) is used for intercepting parasitic interference peaks.

Title: Method of receiving bit streams which are transmitted on a plurality of parallel lines of different lengths.
IPC: H04L1/20
Filed: 1981-09-25
Abstract: Bit sequences combined to form transmission blocks of a particular length arrive in a receiving and evaluating device ES via several parallel lines of different length, the individual bits being sent in a fixed time frame. For the parallel evaluation of the bit information, the different length of the individual lines L1 to Ln is to be equalised without special circuit measures having to be taken in each receiving and evaluating device ES. By allocating one shift register (SR1 to SRn) per line (L1 to Ln) and sampling the lines with a pulse series which is within the time frame, the sampling results present per line can be picked up in parallel at the output of the shift registers. In addition, bits which are too long or too short can be eliminated by means of a particular selection of the sampling pulses becoming effective.
