The platform 7 has a thumb catch 7a operable to rotate the platform 7 so that a part 7m (Fig. 10) thereof pivots a lever 33 which opens the poppet valve 27. The poppet valve 27 is urged to the closed position by a spring 32 (Fig. 7) which acts on one end of a lever 20 pivotably secured to the body 1 by a screw 19 and having a forked end 20a which engages the poppet valve 27. The actuating lever 9 is pivotably secured to the body 1 by a screw 18 and has a cylindrical part 9a having cam surfaces (39a, 39b, Fig. 8, not shown) which co-operate with further cam surfaces (41a, 41b) on the element 22. In operation, the thumb wheel 5 is rotated and the thumb of the user strikes the catch 7a to rotate the platform 7 and the cap 2. The rotation of the cap 2 causes an aperture 3 therein to be aligned with the burner poppet valve 27 for the passage of flame. The platform 7 and the cap 2 are returned to the rest position by means of the resilience of the tongue 7h which engages a projection 1d on the body 1.

Title: Pneumatic operating mechanism for a circuit interrupter with piston device having an opening piston and a closing piston
IPC: H01H33/32
Filed: 1969-09-03
Abstract: A high-speedactuator 27 for a gas blast switchcomprises a closing piston 16 and a larger opening piston 15 operating in a cylinder 20, 21 and coupled to a movable contact of the switch (29, Fig. 6, not shown).. Upward movement of a pull rod 14 moves the contact (29) to its open position, allowing blast gas to enter the nozzle-shaped contacts, and closes a downstream blast valve (33, Fig. 6, not shown) towards the end of the opening movement. The upper side of the closing piston 16 is always subject to the high pressure of SF 6 in the contact space the lower side of the opening piston 15 is connectable by a control valve 23 either to the high-pressure or to a low-pressure chamber to close or open the switch respectively. In order to slow the movement of rod 14 at either end of its travel a piston 18 is mounted on the rod and moves in a cylinder 41 filled with high pressure SF 6 and having apertures 41a in its walls and non-return valves 45, 46 in its ends the apertures 41a are adjustable by screws 43. In order to ensure a constant opening and closing speed the flow of gas to and from the space below piston 15 is controlled by a valve 35 (Fig. 10, not shown) responsive to the-high pressure. In a three phase arrangement (Figs. 1-4, not shown) the three operating rods are coupled together to a common actuator (2) at ground potential. Each of the three switches has a generally U-shaped configuration (Figs. 5A, 5B, 5C, not shown) comprising in one arm .the contacts, blast valve and actuator 27 and in the other an SF 6 filled terminal insulator current transformers (C.T.) are fitted near the base portion.

Patent ES-415869-A1 (ES)
Title: Circuit arrangement for generating a control signal for the field output stage in a television receiver
IPC: H04N5/06
Filed: 1973-06-13
Abstract: A circuit arrangement for generating a control signal for the field output stage in a television receiver provided with a frequency divider circuit with which the double line frequency is divided either by a number which is equal to the number of lines per image or by a number which deviates from this number. The choice between the two divisors is made by a storage element dependent on the on-phase state or the off-phase state of the received field synchronizing pulses and the divider pulses. Resetting of the frequency divider circuit is therefore realised by the store and not by the received pulses, which results in less sensitivity to interference. Since there are two states, a small brightly lit image no longer occurs. In the case of the nominal divisor, the divider pulse is extended. When receiving non-standard signals (for example, from video recorders) direct synchronisation is used with the divisor being larger than the nominal divisor.
Patent ES-428794-A1 (ES)
Title: Method and apparatus for low pressure die casting
IPC: B22D18/08
Filed: 1974-07-31
Abstract: A method of low pressure die casting in which molten metal in a furnace is forced up a riser tube into the die by gas pressure applied to the surface of the molten metal in the furnace by a pressure circuit, wherein as the level of the metal in the furnace falls after each successive die filling operation, the resultant increase in the time taken to exhaust the furnace pressure is utilised to produce compensatory incremental changes in the pressure applied in the circuit. The die casting apparatus for carrying out the method includes a remotely controlled pressure control valve which is controlled by a pressure adjusting means operable during the exhausting period of the furnace to apply the incremental changes in pressure to said valve. The apparatus may employ a single or a two-stage pressurisation.

Filed: 1977-06-03
Abstract: A method and apparatus for forming solid bodies by removing material from solid workpieces. A workpiece is situated between oppositely rotating tools which remove material from the workpiece, these tools having hollow interiors facing each other and each conforming to the configuration of one half of the finished body. The hollow interiors of the tools have teeth for removing material from the workpiece, and while the tools are rotated oppositely the distance therebetween is due so that from the workpiece a body is gradually formed, this body finally becoming almost completely enclosed within the hollow interiors of the tools, whereupon the latter have the distance therebetween increased so that the body formed thereby can be removed. These tools are adapted to form from a workpiece bodies of full circular or ring-shaped configuration, and the hollow interiors of the tools are provided with raised teeth similar to file teeth, for removing material from a workpiece. In addition, each tool is formed with openings extending outwardly from its hollow interior so that the material removed by the tool from the workpiece can travel outwardly through these openings.
