Patent ES-356124-A1 (ES)
Title: A Process for the Introduction of Scrap into a Liquid Metal
IPC: F27B3/22
Filed: 1968-07-13
Abstract: A method of continuously supplying an additional charge of metal in the form of scrap into the enclosure of an enothermic refining process, includes charging scrap into a melting space, chamber 3, the lower part of which is in communication with a refining space, chamber 1, via an orifice 10. A pile of scrap is maintained in chamber 3 by a feed from conveyor 13 and is progressively melted owing to the temperature gradient between the refining chamber and the melting chamber. Liquid metal to be refined is added to chamber 1 through orifice 4. The oxygen jet from lance 6 produces a foam of refined metal and slag which over-flows into chamber 2 the slag settles and is withdrawn via orifice 8 while the underlying molten metal flows over spout 9. The rate of feed of scrap may be adjusted depending on the rate of melting, so as to obtain a steady position of the melting front. In an alternative embodiment Fig. 2 (not shown) refining is carried out in the refining chamber by oxygen blown through a porous element in the base of the chamber as well as through the lance, and also by oxygen blown through a porous element in the base of the settling chamber

Title: Flexible line gripping device
IPC: A62B1/14
Filed: 1968-08-23
Abstract: A device for gripping a flexible line 24 such as a rope comprises in combination, means 50, 50' having transverse members 58, 74 extending therebetween positionable on opposite sides of the line, means 26, 26' for applying a torque to rotate said first means so as to move said members transversely with respect to said line to contact the line and haul it into a hitch such that the line is securely gripped by the device, said first means being constructed whereby counter-torque can be simultaneously applied thereto for controllably releasing said line. In the construction shown the means 50, 50' are a pair of circular side plates, and their shapes allows them to be rotated manually to apply the counter torque the member 58 is a projection from the plate 50 which extends through an opening in the plate 50' its end portion being welded to the plate 50'. The member 74 is a pin which is slidable in a bore 78' of the plate 50' and which has a snap ring 84 disposed in a circumferential recess which engages a shoulder at the end of a counter bore 78 in the plate 50 when the pin 74 is in its fastening position. The means 26, 26' for rotating the plates 50, 50' consist of a pair of control lines which are respectively secured to the plates 50, 50' and extend in circumferential grooves in the plates. The free ends of the control lines are connected together by a clevis 32. Each of the plates 50, 50' has a hub 59, 59' and attached to each hub is a generally triangular plate 90, 90' each plate being attached to its hub near one apex and the plates being connected together near their other apices by tubular stems 102 on which rollers 100 are mounted. One roller bears on the line 24 and the other on the control lines 26, 26' and in the operative condition of the device the plates prevent withdrawal of the pin 74. In the inoperative condition of the device the plates can be rotated to align notches in the plates with the pin 74 to enable the pin to be withdrawn so that the flexible line 24 can be positioned between the projection 78 and the pin 74. In Fig. 1 the device is shown for gripping the line 24 which is supporting a platform 10 the line passing round pulley blocks 17, 19. The control lines are attached to a bracket 28 which is itself attached to a loop 14 of the platform and the arrangement is such that when the device is in engagement with the bracket it is in its releasing position in which the line 24 passes straight down between the projections 78 and the pin 74 with the control lines are substantially contained in the circumferential grooves of the plates 50, 50'. The upper surface of the bracket is arcuate so that it engages the circumference of each plate 50, 50' and the bracket is bifurcated so that the line 24 can pass through the bracket. Other uses of the device are described.

Title: Spark ignition apparatus for internal combustion engines
IPC: F02P7/067
Filed: 1973-08-18
Abstract: Spark ignition apparatus for an internal combustion engine including a hollow casing rotatably supporting a shaft driven by the engine in use. A sensor is positioned within the casing, and is mounted for angular movement about the rotational axis of the shaft. The sensor is sensitive to the angular position of a member which rotates with the shaft. A housing is carried by the casing and receives the components of an electronic circuit which is operated in response to the output from the sensor. The electronic circuit in response to the output from the sensor breaks and restores an electric circuit through the primary winding of the ignition coil of the ignition system of the vehicle. Supported by the housing is a vacuum actuator the moving rod of which is coupled to the sensor. Thus the actuator which in use communicates with the inlet manifold of the internal combustion engine adjusts the position of the sensor relative to the casing of the apparatus in accordance with the pressure conditions in the engine inlet manifold.

Title: Vehicle control unit
IPC: B61L7/10
Filed: 1978-01-19
Abstract: A vehicle control unit for a short-distance traffic system is disclosed wherein a plurality of vehicles are controlled from a center. Each vehicle carries at least two on-board computers each of which process the control commands coming from the center to provide commands to on-board units and compiles telegrams to the center concerning the condition, location and speed of the vehicle in response to information from the on-board units. Both computers perform the necessary processing independently of each other. A comparator ensures that commands to the on-board units and the compiled telegrams are not sent until this information is received in identical form from both computers. Each computer delivers life signals at regular intervals to an associated emergency brake circuit, which initiate emergency braking if life signals from the associated one of the computers are not received within a given period of time. In the event of a malfunction in a computer, a standby computer or a pair of standby computers is put in action.
