Title: Arrangement for converting a pal color television signal to an ntsc color signal
IPC: H04N11/20
Filed: 1968-04-09
Abstract: P.A.L. signals are converted into N.T.S.C. signals in a circuit wherein the P.A.L. chrominance signals separated out by amplifier 14 from the output of receiver 11, are applied in anti-phase, by means of transformer 22, to two inputs of a balanced modulator comprising transistors 20, 201, 2011, 25, 251, and 2511 and the synchronous output of a frequency doubler 171 at twice the chrominance sub-carrier frequency is applied in phase to a second pair of inputs of said balanced modulator during odd time intervals. Thus during said odd line intervals the balanced modulator produces a difference frequency side band output having the same sub-carrier frequency as the initial P.A.L. signal but with the phase and modulation sequence reversed. During even line intervals a bi-stable circuit 1711, controlled by the horizontal sync. pulses and controlling the frequency doubler output, produces a signal which, via transistor 50, unbalances the modulator, whereby the chrominance signal passes unaltered therethrough. The output of the modulator is connected to a colour demodulator 16 and comprises consecutive line chrominance signals all having the same phase sequence, i.e. an N.T.S.C. signal. The balanced modulator comprises two difference amplifiers or long-tailed pairs, a first pair comprising transistors 20 and 201 with a transistor 2011 forming a high impedance emitter input and the second pair comprising transistors 25 and 251 with high impedance emitter input transistor 2511. The collectors of the pair transistors are cross-coupled to load resistors 21 and 26. The bases of transistors 201 and 251 are coupled to ground by capacitor 23 and the frequency doubler output is connected in phase to the bases of transistors 20 and 25. The bases of transistors 2011 and 2511 receive the chrominance signals in antiphase. A difference frequency signal will thus appear across load 21. During the even lines transistor 50 is rendered conductive and unbalances the modulator. A potentiometer 53 is adjusted so that the amplitudes of the output signals for the balanced and unbalanced conditions of the modulator are equal. A circuit, substantially corresponding to Fig. 1, but comprising integrated circuits is described (Fig. 2, not shown).

Title: Automatic digital fuel indicator,particularly for car
IPC: G01F9/00
Filed: 1968-12-27
Abstract: Pulses from a vehicle petrol flow meter 1 pass via a gate 7 to a counter 4 the gate 7 being held open by a bi-stable circuit 6 whilst the vehicle travels a predetermined distance, e.g. 10 miles. In operation actuation of a switch 8 zeroises the counter 4 and readies the gating arrangement 6, 7 so that the next pulse to arrive via a pulse shaper 5 from a distance measuring device 2, 2A, turns the bi-stable 6 on, thereby opening the gate 7, and the next pulse (which occurs after the predetermined distance has been traversed) turns the bi-stable off and closes the gate. Subsequent pulses from the displacement transducer are ineffective until the zeroising switch 8 has been reactuated.

Title: Shear Plates for Dry Shavers, and Process for Manufacturing the Shear Plates
IPC: B26B19/38
Filed: 1969-03-13
Abstract: A perforated shear-plate for dry shavers comprises a main body 1 made from steel foil and having a network forming bridges 2 between the holes 1 so as to provide rims 3 which are flanged and ground, the main body of the shear plate consisting substantially of a soft, hardenable steel, whereas in the region of the flanged and ground rims of the holes, the material has a sub-microscopic, over-quenched martensitic structure containing residual austenite. The shear-plate is produced by first stamping a strip of steel containing at least 5% carbon, the strip being stamped to produce several shearplates. The strip is then mounted on the periphery of a massive metal drum with the flanges facing outwardly, the drum then being rotated slowly and the strip thrust against the surface of a rapidly-rotating disc of high-speed steel which grinds the strip and also causes an abrupt development of heat in the region of the rims 3. As soon as the required temperature is reached, the strip is cooled by the mass of metal in the drum. The surfaces of the rims are simultaneously ground during the heating process. The strip of foil is finally separated into individual shear-plates.

Patent ES-432577-A1 (ES)
Title: Magnetically actuated switching device
IPC: H01H1/66
Filed: 1974-12-04
Abstract: A magnetically actuated switching device using reversibly magnetizable armatures treated by a selective annealing process. The annealing process changes the homogeneous coercive magnetic properties of the armatures so that the highest coercive force is caused to occur in the region of the armature which is subjected to magnetizing forces from an energizing coil, and the region of the armature existing outside the magnetizing field is annealed in a manner to lower the coercive force of the armature. Selectively annealing the armature to provide high coercive force in the vicinity of the magnetizing coil reduces the amount of magnetizing force necessary to be supplied by the coil for switching the armature from a closed to an open contact position.

Title: Movable expansion valve
IPC: F25B13/00
Filed: 1976-06-22
Abstract: An expansion device for use in a reversible vapor compression refrigeration cycle for producing, upon demand, either heating or cooling. Two devices are mounted in opposed relationship in a supply line carrying refrigerant between a first heat exchanger and a second heat exchanger. Each expansion device includes a body having a flow passage therein opening into an expanded chamber. A free-floating piston is slidably mounted in the chamber and is moved to a first position when refrigerant is passed through the line in a first direction and to a second position when the direction of flow is reversed. A centrally located metering port passes through the piston while fluted channels are formed in its outer periphery. When in the first position, the fluted channels are closed against one side wall of the chamber and refrigerant is throttled through the metering port from the high pressure exchanger (condenser) into the low pressure exchanger (evaporator). Reversing the direction of refrigerant flow causes the piston to be moved into the second position wherein the fluted channels are opened to the supply line to allow an unrestricted flow of refrigerant about the piston.

Patent ES-464046-A1 (ES)
Title: Oil burner
IPC: F23D11/38
Filed: 1977-11-11
Abstract: Light fuel oil of low viscosity is supplied to a pressure atomizing oil burner. A flow heater which is positioned upstream of the pressure atomizing nozzle, preheats the fuel oil to a temperature of approximately 150 DEG C. but not over the coking and cracking temperature of the fuel. With heat efficiencies up to approximately 25,000 kcal/hour density and viscosity are continuously decreased in the flow heater in order to reduce the thickness of the oil film leaving the atomizing nozzle and thus to decrease the flow rate. With heat efficiencies higher than approximately 25,000 kcal/hour density and viscosity are decreased before the ignition phase by preheating, in order to reduce the thickness of the oil film flowing out of the atomizing nozzle and thus to decrease the flow rate in the following ignition phase. After the ignition phase the preheating is reduced or stopped.
