Title: Liquid fuel injection pumping apparatus
IPC: F02M41/14
Filed: 1980-01-16
Abstract: A liquid fuel injection pumping apparatus includes a rotary distributor member 12 housed in a sleeve 11 mounted in a body 10. The distributor member is movable in an axial direction and mounts a pumping plunger 15 in a transverse bore 14. An inclined surface is formed on the plunger for co- operation to limit the outward movement of the plunger, with an inclined surface 34 on a part in the form of a strip 27. The strip rotates with the distributor member but is restricted against axial movement. Hence axial movement of the distributor member varies the amount of outward movement of the plunger and hence the amount of fuel which can be supplied by the apparatus.

Title: End cap assemblies for conveyor rollers
IPC: F16C13/02
Filed: 1980-03-07
Abstract: A conveyor roller comprises a roller tube fitted with end cap assemblies incorporating bearings for rotatably mounting the roller tube on a fixed shaft.

Title: Method and circuit arrangement for detecting the entry and/or the departure of a vehicle, especially a road vehicle, into or from a specified surveillance area.
IPC: G08G1/042
Filed: 1980-06-20
Abstract: A method and a circuit arrangement for determining the entry and/or exit of a vehicle into or out of a predetermined monitoring zone, which is defined by at least one inductive measuring loop whose change in inductance, which occurs as a result of the entry of a vehicle into the monitoring zone or the exit of a vehicle out of the monitoring zone, is used to control the oscillation frequency of an oscillator circuit is disclosed. In this method a measuring signal which corresponds to the oscillation frequency of the oscillator circuit and a reference signal which corresponds to a reference oscillation frequency are subtracted from one another. The difference signal thus formed is processed in an analysis device for display purposes. In order to achieve a relatively high degree of measuring accuracy, while employing circuit components which possess a relatively low operating frequency, it is provided that the measuring signal which corresponds to the oscillation frequency of the oscillator circuit is obtained and that on the occurrence of a first measuring pulse in a measuring pulse sequence derived from the oscillation signal of the oscillator circuit and with a reduced pulse rate, at the beginning of a measuring interval determined by a preselectable number of measuring pulses, a bistable trigger element is set to emit a specific output signal. On the occurrence of the output signal, which, for the duration of the selected measuring interval, counting pulses are counted with a pulse rate which is high in comparison to the pulse rate of the measuring pulses in a counting pulse counter whose counter signal, which is emitted at the end of the selected measuring interval, is made available as the measuring signal which corresponds to the oscillation frequency of the oscillator circuit.
Patent ES-8104091-A1 (ES)
Title: Two-circuit pressure control unit
IPC: B60T8/30
Filed: 1980-07-04
Abstract: Twin brake force control units, for a two circuit brake system are known in which the initial control force is changeable dependent on the vehicle load. The control force is distributed to the control pistons by a lever. Due to tolerances and erosion of the individual elements considerable differences in pressure in both brake circuits may occur. This is overcome according to the present invention by providing a lever which directly operates upon both control pistons and which is rotatable about an axis perpendicular to the shifting movement of the control pistons and which is additionally rotatable about its longitudinal axis. This double rotation of the lever is accomplished by supporting the lever in a spherical joint.
Patent ES-8106363-A1 (ES)
Title: Air distribution apparatus, especially for oversaturated air
IPC: F24F13/06
Filed: 1980-09-10
Abstract: In the openings at the side wall of an infeed or inflow channel there are inserted outlet or discharge elements having an oval cross-section which continuously tapers in the flow direction. The inlet-side portion of the outlet elements, protruding into the interior of the infeed channel, possesses an outwardly drawn or flexed end portion or section which terminates in spaced relation from the channel side wall and forms therewith a catch trough. Within this trough there is entrapped water which is deposited at the inner surface or wall of the infeed channel and which flows downwardly along the channel side wall. At the outlet side of each outlet or discharge element there is arranged a further catch trough which extends at the inner surface of the outlet side or opening along the circumference. This inwardly open catch trough is formed by an end portion or section of the outlet element which is flexed or bent back towards the inside. By means of this catch trough the water which has been separated at the inner surface of the outlet element is prevented from reaching the region of the outlet opening. The base portion of the outlet element is constructed as a collecting trough which returns the separated water back into the interior of the infeed channel. Without the need to provide the outlet element with water separation elements arranged in the flow cross-section, there is avoided the exit of large water droplets out of the outlet or discharge elements.

Patent ES-8202996-A1 (ES)
Title: Adaptive decision level circuit.
IPC: H04L25/03
Filed: 1981-02-26
Abstract: The adaptive decision level circuit (FIG. 3) slices a digital signal with respect to a decision level disposed between the signal levels. A correction signal generated from the sliced signals (S, S) compensates for variations in the signal levels by maintaining the decision level at a constant position relative to the signal levels. The correction signal is generated by comparing (321) the integrated difference (on lead 305) between the sliced signal and its complement with the statistically expected value (312) of the difference between the sliced signal and its complement. In the preferred embodiment, the expected value is equal to one-half the signal swing of the sliced signal.
