Title: Remote control of electrical devices
IPC: A63H19/24
Filed: 1979-08-14
Abstract: A remote control system for use e.g. in controlling the locomotives and ancillary devices of a model train layout comprises a transmitter and a number of receivers incorporated in the devices to be controlled. A composite waveform is applied across the tracks, comprising a rectangular power supply waveform with intervals between positive and negative path cycles and control signals which occur in the latter parts of these intervals, the delay between the end of each half cycle and the control signals allowing time for reactive currents resulting from inductive loads to decay. The composite waveform is synthesized by two switching amplifiers driven by a microprocessor and having associated with it slider controls and a keyboard for controlling the receivers. The receivers are programmed to identify control signals addressed to them and to control an associated locomotive or an ancillary device appropriately. The address to which each receiver responds can be programmed by selective breaking of a number of tabs on a circuit board on which the receiver IC is mounted.

Patent ES-8105911-A1 (ES)
Title: Video image vertical detail restoration and enhancement
IPC: H04N9/64
Filed: 1980-05-09
Abstract: In a color television receiver including a comb filter for separating luminance and chrominance components of a color television signal, a network is included for selectively restoring and enhancing vertical image detail to preserve and enhance vertical resolution in the luminance content of a displayed image. The comb filter provides a combed luminance signal output from which vertical detail signal information has been unavoidably deleted, and a combed chrominance signal output including signal frequency components representative of the deleted signal, which are selectively extracted from the combed chrominance signal. Low level detail signals are restored to the combed luminance signal via a first signal processing network with a prescribed restoration gain. The detail signal is also combined with the combed luminance signal via a second signal processing network which cores (removes) low level detail signals including noise, and enhances higher level detail signals through amplification to enhance vertical image definition. A resultant reconstituted luminance component manifests restored low level vertical detail information as well as enhanced higher level vertical detail information, without enhancing unwanted signal components such as noise.

Title: Process and apparatus for the electromagnetic casting of metals and non-magnetic screen for use therein.
IPC: B22D11/01
Filed: 1980-06-26
Abstract: An electromagnetic casting process and apparatus is described and claimed for electromagnetically casting ingots having at least one corner or region of small curvature, e.g. rectangular ingots, in which means are provided which locally reduce the magnitude of the electromagnetic force field used to shape the ingot in the region of the corners so that metal flow into the corners is promoted. The localised reduction of electromagnetic force field is obtained either by using a non-magnetic screen (32) which provides increased screening in the corner regions of the ingot or by shaping the inductor (11) to provide a greater air gap between the inductor and the ingot in those corner regions. Optionally cooling fluid is applied asymmetrically to the ingot surface so that the solid-liquid interface (25) is locally lowered in the corner regions. Non-magnetic screens which provide increased screening and localised reduction of the force field in the corner regions of the ingot are also claimed.
Patent ES-8102449-A1 (ES)
Title: Noise tolerant multiplex system
IPC: H04L5/22
Filed: 1980-07-01
Abstract: A noise tolerant time division multiplex system including a transmitter and receiver, each constructed as a monolithic integrated circuit and interconnected by a serial data wire. Data as well as power is supplied to the transmitter from a plurality of parallel connected input switches. The transmitter includes a parallel in/serial out shift register controlled by timing logic and further includes a tri-state driver for generating a three-level serial output signal indicative of the status of the input switches. The data is generated at a high rate to eliminate any deleterious effects of noise on the system. The receiver chip receives a regulated energizing potential from the transmitter chip over two additional wires, generates a timing signal from the three-level signal and loads the data in binary format into a serial in/parallel out shift register. When the data is properly positioned in the receiver register the data is transferred to latches which energize appropriate relays to control the direction of rotation of various motors controlling the seats, windows and door locks of an automobile.

Patent ES-8204678-A1 (ES)
Title: Audio frequency track circuit for rapid transit applications with signal modulation security
IPC: B61L23/16
Filed: 1981-05-22
Abstract: An audio frequency track circuit with improved security in the train detection function for rapid transit applications for use with uninsulated rails includes an improved transmitter and receiver. The transmitter modulates a track frequency carrier with a fixed code rate, regardless of the code rate employed to modulate the train information frequency. The receiver includes a decoder tuned to the track frequency modulation rate. By using such a sharply tuned decoder, the noise protection threshold is increased. Because of its application to uninsulated rails, with the associated lack of hard track circuit boundaries, adjacent track circuits have different track frequency modulation rates to insure that the modulated track frequency signal, from one track circuit, is not effective to operate a track relay in another circuit even under failure conditions.
Patent ES-8306952-A1 (ES)
Title: Intensity regulator, especially a light regulator
IPC: H05B41/392
Filed: 1982-06-15
Abstract: Intensity regulator, especially a light regulator which can be adapted to the regulation of the light intensity of both compensated and uncompensated illuminators connected to the alternating-current mains. The regulator comprises one or more switch elements (S1, S2) disposed in a circuit between the mains and an illuminator (L) as well as a control logic circuit (4) for the switch element or elements, said circuit upon the intensity regulation breaking the supply current at least once on each half-cycle when current has been conducted from the O-moment of a half-cycle to the moment according to a set value. On one hand, a problem is the elimination of current peaks produced by voltage differences at a switch-on moment and, on the other hand, the arrangement of a control for the switch elements. To overcome the problem, the switch element (S1) is a double-switch two-way switch element connected in series with a load (L) and controlled on each half-cycle to break the current only from the mains towards the load but to permit the current flow in the opposite direction. The other two-way switch element (S2) is coupled parallel to load (L) and controlled on each half-cycle to block the current flow in the direction of the mains voltage but to permit the oppositely directed current flow therethrough. In order to determine the current breaking moment of the switches of the first switch element (S1), the control logic circuit is provided with an integrator, a mains voltage O-moment sensor and reference voltage setting means, whereby from the O-moment of the mains voltage, with the integrated voltage reaching a set reference voltage, the integrator provides a control data to a comparator logic for breaking the current of switch element (S1) in said direction.
