Title: Optical arrangement for a smoke detector using the light scattering principle.
IPC: G08B17/10
Filed: 1980-12-19
Abstract: An optical arrangement for a light scattering type smoke detector has a radiation transmitter and receiver which are each preceded by a lens for obtaining a generally parallel field of view for each of the transmitter and receiver.

Patent ES-8606152-A1 (ES)
Title: Electronic sensor for brake systems in vehicles.
IPC: G01P3/56
Filed: 1984-10-31
Abstract: The invention relates to an electronic sensor for determining the start time and duration of the brake relief phase in brake force modulation cycles in vehicles with so-called antilock brake systems. A tachometer (10) detects the rotation speed of the wheels. The output signal of the tachometer is differentiated in a differentiating circuit (20) and is compared to a reference signal (a0) from a reference value generator (30). A switch (60) is switched-on by the output signal from the comparator (40) when the differentiated signal has reached the reference value. Thereby a break force reduction phase of the brake force modulator (80) is started. A reference and sampling circuit (50) stores the instantaneous speed signal (w(t)) from the tachometer (10) and samples the instantaneous value (w(t0)) of this signal at that point in time when the differentiated signal (a(t)) has reached the reference value (a0). The reference and sampling circuit (50) also provides a reference signal (M) representing a reference speed that is supplied to one input of a second comparator (70) and in this comparator is compared to the speed signal (w(t)) from the tachometer (10). The output signal of the second comparator (70) switches off the switch (60) when the speed signal (w(t)) from the tachometer (10) has reached the speed reference signal level (M). Thereby the switch (60) switches off the modulation system (80) and once again lets through the signal (w(t)) to the sampling circuit. The slope of the reference signal (M) is controlled by the modulated brake force.

Title: Equipment for applying a blank of foil to bottles
IPC: B67B5/03
Filed: 1984-12-05
Abstract: In equipment that is intended for applying a blank of foil to bottles and that includes a turntable, at least one labeling station, a rotating transport star that has accommodations for the bottles and is positioned downstream of the turntable, and a rotating transfer-and-application device consisting of several similar units distributed around its circumference with elements that fold and press down the ends of the blank extending beyond the head of each bottle, the pressure-application elements and if necessary the folding elements are, as they revolve, kept outside the circumference of the elements on the turntable that accommodate the bottle. This avoids collisions at this point. The axis of rotation of the pressure-application elements and the axis of rotation of the output star are accordingly mutually eccentric in such a way that the orbits of the accommodations and of the pressure-application elements coincide along one segment. The equipment will not malfunction and will ensure satisfactory bottle foiling.

Abstract: A method of determining the operability of a source range detector located adjacent a nuclear reactor in which the source range detector generates a count corresponding to the neutrons emitted by the reactor when the reactor is operating within the source range and a predetermined voltage is applied across the electrodes of the detector, the detector being subject to destruction when the reactor power level is above the source range and the predetermined voltage is applied across its electrodes. The method includes the steps of: (a) operating the reactor at a power level above the source range (b) applying a voltage across the electrodes of the detector, the voltage having a magnitude below that necessary to generate a neutron count from the detector (c) gradually increasing the magnitude of the voltage across the electrodes of the detector until the detector just begins to generate a neutron count (d) reducing the voltage across the electrodes of the detector and (e) replacing the detector if a neutron count is not generated in step (c) at a voltage having a magnitude less than the predetermined voltage.
