Title: Disk brake
IPC: F16D65/097
Filed: 1977-03-21
Abstract: A vehicle disc brake assembly is attached to a fixed mounting bracket (10). The brake piston (44) acts on the friction pad (23a) on one side of the brake disc (11). A reaction bracket (14) transmits the reaction force from the brake cylinder (42) to the friction pad on the other side of the brake disc (11). An anchor bolt (60) for the brake cylinder is provided outside the cylinder and parallel to its axis. An external fork (65) on the cylinder engages the anchor pin (60). Any lateral forces which are produced when the brakes are applied are thus taken up by the anchor bolt location.
Patent ES-466099-A1 (ES)
Title: Gravitational separator for mixtures of immiscible liquidsof diffreent densities
IPC: B01D17/04
Filed: 1978-01-18
Abstract: An oil-water mixture is fed through a feed line (12, 240, 242) to the separator tank (10). Separated oil flows out through an outflow line (250, 251). Falling water is taken off through an outflow line (214, 216) after it has flowed through coalescer screens (200). The falling water passes into the coalescer chamber (202) with the coalescer screens (200) through non-return valves (210). For backflushing, clean water is introduced through the outflow line (214, 216) into the coalescer chamber (202). This water flows through the coalescer screens (200) and then through the non-return valves (212), into the coalescer hood (250) and from there through the line to the upper part of the tank (10). Because of the non-return valves (210, 212) the separation is improved and, in particular, an upwardly directed flow is obtained during backflushing. A virtually complete removal of the oil droplets from the coalescer screens is thus achieved during backflushing.

Title: Apparatus for the mixing of different streams of air in a cooling tower
IPC: B01F5/06
Filed: 1980-06-23
Abstract: Apparatus for the mixing of different streams of air and particularly dry and moist streams of air, in a cooling tower. In order to obtain an effective low-loss mixing over a short flow path by simple means, eddy fields are produced by at least one cylindrical flow body arranged transversely to the direction of flow of one of the streams of air (the main air stream) in the cooling tower as a result of the burbling or separation of the flow on the sides of the body. The transverse components of the eddy fields produce an intensive mixing of the different streams of air.

Patent ES-8206066-A1 (ES)
Title: Signal communicator.
IPC: B60C23/04
Filed: 1981-04-27
Abstract: A signal communicator for transmitting an electrical signal from one member rotating relative to another member is in the configuration of a journal bearing and comprises at least one conically shaped annular graphite ring supported by inner and outer electrically conductive races. While one race is insulatively mounted on the rotating member and electrically connected to a condition sensor, the other race is insulatively mounted on the relatively stationary member and electrically connected to a signal detector, and the graphite ring is an electrical conductor interconnecting the sensor and detector via the two races. Alternatively, two opposing and contacting graphite rings are mounted in nonconducting carriers, one of the carriers keyed for rotation with the sensor while the other is mounted on the relatively stationary member. Electrical connections are made directly from the sensor to one of the graphite rings and from the detector to the other of the graphite rings and the rings therefore function as the electrical interconnection between the rotating sensor and the relatively stationary detector.
Patent ES-8204265-A1 (ES)
Title: Active distortion elimination circuitry for a video disc player
IPC: H04N5/93
Filed: 1981-06-17
Abstract: In a video disc system, the picture display is adversely affected by intermodulation distortion occuring in the signals recovered from the disc record. A non-linear circuit, responsive to a bias signal, generates a compensation signal in a diode modulator for cancelling the undesired distortion components of the recovered signal. The resulting distortion after cancellation is measured in a comparator circuit to determine if the distortion has increased or decreased. The comparator circuitry outputs an appropriate signal to bias the non-linear circuit to further reduce the distortion components. A small oscillation is superimposed on this bias signal, which oscillation simplifies the comparator circuitry and forces the circuit to search for an optimum operating point.
