Title: Simplified automatic advance ignition system for an internal combustion engine
IPC: F02P1/08
Filed: 1973-02-13
Abstract: In an ignition system in which the spark coil is wound right on the magneto armature and the spark is produced by electronic interruption of a short circuit across the primary winding, the first of a succession of rectified half waves applied to the electronic circuit unit has its amplitude reduced either by insertion of a circuit component in one half wave path of the rectifier to provide damping, or by the configuration of the armature core, or both.

Title: Video display system employing drive pulse of variable amplitude and width
IPC: G09G3/28
Filed: 1974-05-17
Abstract: A video display system employs a flat panel of the X-Y matrix type with a brightness control circuit in which both the amplitude and the duration of driving pulses for the display panel are varied in response to variations in the sequentially sampled level of input video signals. In a preferred brightness control circuit, variations in the sequentially sampled level of the input video signals are converted into digitally coded signals which selectively energize respective pulse generators operative to produce pulses of correspondingly weighted durations and amplitudes which overlap in time, and such pulses are combined to provide the amplitude- and width or duration-modulated driving pulses for the display panel.

Patent ES-430921-A1 (ES)
Title: Arrangement for adjusting the damping force of a shock absorber
IPC: F16F9/44
Filed: 1974-10-11
Abstract: An arrangement is provided for adjusting the damping force exhibited by a hydraulic shock absorber. Included is a valve near the piston including passages permitting the flow of fluid through openings in the piston. A linkage is provided which is rotatable about the piston rod to close any or all of the passages through the valve and thus regulate the damping force. The position of the linkage is determined by the interaction of the linkage with a stop member and the piston rod. The stop member is an element which may be extended through one end of the cylinder to engage an extension of the linkage to hold it in place while the piston rod bearing the valve is turned to open or close openings in the valve and thus change the damping force the shock absorber can exert. The stop member is adaptable to be retracted from contact with the linkage so that the adjustment will not be disturbed. Click-stops are provided between elevations on the linkage and apertures affixed to the end of the piston to provide "feel" and perceptible noise to indicate intermediate positions have been reached.
Patent ES-431446-A1 (ES)
Title: Expanding tobacco
IPC: A24B3/18
Filed: 1974-10-29
Abstract: A process for expanding tobacco is provided which employs liquid carbon dioxide as the expansion agent. Tobacco is contacted with liquid carbon dioxide to thoroughly impregnate the tobacco with the liquid carbon dioxide. The carbon dioxide impregnated tobacco is maintained at a temperature no lower than -2 DEG C. and under conditions of temperature and elevated pressure such that all or substantially all of the carbon dioxide which is in contact with the tobacco is in liquid form. After the impregnation has been completed, any excess liquid carbon dioxide which may be present with the tobacco may be removed from the tobacco. The elevated pressure is then reduced in order to convert the liquid carbon dioxide to solid carbon dioxide within the tobacco structure. The resulting solid carbon dioxide-containing tobacco is then subjected to conditions of temperature and pressure, preferably by rapid heating at atmospheric pressure, such that the solid carbon dioxide is vaporized and the tobacco is thereby expanded. Apparatus for carrying out the above described process is also provided.

Title: Apparatus for reducing the instruction execution time in a computer employing indirect addressing of a data memory
IPC: G06F9/38
Filed: 1978-02-24
Abstract: Instructions which are read from a program memory of a control computer employing indirect addressing of a data memory are stored temporarily and sequentially in a buffer memory to form an execution queue. The absolute address to the data memory is generated by an address calculator by means of a base address derived from a reference memory in correspondence to an input address and by means of at least one address parameter which has been recorded in a register memory in connection with the execution of an instruction read from the buffer memory and transferred to a parameter register prior to the address calculation. In addition to each instruction, information is recorded in the buffer memory to indicate on the one hand whether the instruction is of the type which performs a write or read operation in the data memory and on the other hand whether it is of the type which enters address parameters in the register memory. This additional information is continually monitored and, when it shows that the address parameters will not be changed by any instruction in the queue ahead of a write or read instruction which has just entered the queue, the required address calculation process is initiated.

Title: Fluid-filled friction clutch
IPC: F16D35/02
Filed: 1979-02-02
Abstract: A fluid friction clutch especially for powering a rotary cooling fan for an internal combustion engine. The clutch has a driven part with a drive disc rotating in a drive chamber which is separated from a fluid reservoir chamber by a separating wall within the clutch housing.

The temperature-dependent element is an expansion element containing a substance which undergoes volume changes as a function of temperature. The expansion element is heated electrically by means of a PTC resistor under the control of a thermal switch which reacts to engine-related temperatures. When the power supply to the PTC heater is interrupted, the clutch engages and provides full cooling power.
