Patent ES-338980-A1 (ES)
Title: Thermistor device and method of producing said device
IPC: H01C7/04
Filed: 1967-04-06
Abstract: A thermistor has two leads ohmically bonded to a doped synthetic single crystal diamond and displays a negative temperature coefficient of resistance of greater than 0.05 over a temperature range in excess of 500 C. The dopant may be boron, aluminium, or beryllium and may be incorporated (in the proportion of 0.001-1.0% by weight of diamond) during the nickel-iron catalysed conversion at 1100- 1700 C. and a pressure of 45-60 kilobars of graphite to diamond. 250-300Á diamonds are separated from residual graphite, catalyst, and pyrophyllite container material by respective treatments with sulphuric-nitric acid, hydrochloric-nitric acid, and dilute hydrofluoric acid. To make the thermistor of Fig. 1 (not shown), a degreased diamond (1) is placed in contact with degreased heat sink-lead assemblies consisting of iron-nickel-cobalt leads (4) welded to molybdenum or tungsten bodies (3) each coated with, for example, a palladium-nickel-chromium alloy (2). These parts were jigged with an alumino-silicate glass preform (5) in a gas-tight furnace containing oxygen-free forming gas of low dew point and heated to form ohmic con tacts and seal the assembly, the leads being pushed inwards during the process. An outer envelope (7) of devitrified glass is applied to protect the lead-heat sink welds. Oxide on the exposed portion of the leads is removed and the leads chromium-plated. Bonding alloys to replace the ternary alloy used are gold-nickelchromium, iron-nickel-cobalt, and palladiumnickel. The lead materials are tungsten, molybdenum, and the following materials which require no protective chromium coat:-platinum, palladium, and platinum-clad molybdenum. If leads are attached directly to the diamond, alloying, diffusion bonding, thermocompression bonding, ultrasonic welding, or nail-head bonding may be used. If headers are used bonding materials may be placed thereon by evaporation, as a slurry, or by firing-on an alloy preform. The atmosphere used in the firing stage and which is retained within the encapsulation, may instead be argon, helium, nitrogen or hydrogen, or the firing may be effected in vacuo.

IPC: B60T8/1763
Filed: 1969-09-30
Abstract: An anti-skid vehicle braking system responsive to tyre road surface conditions including a wheel speed sensor 30 generating pulses converted to a D.C. voltage level in a counter 32, which voltage is supplied to a device 34 which generates no output as long as wheel speed remains below a predetermined threshold value, the output of the device being an emitter follower 35 which reproduces upon its emitter any D.C. voltage applied to the input which is above the threshold value and the output being applied to a terminal X upon which is also established a minimum signal by a voltage divider comprising resistors 38, 39, 40 has also a device 42 responsive to linear acceleration of the vehicle and consisting of a tubular glass envelope containing mercury bridging electrical contacts mounted aligned with the vehicle fore and aft axis so that deceleration moves the fluid to open the circuit. The wheel acceleration signal is applied to comparators 50, 52, 54 wherein it is compared to a predetermined reference level. When the wheel decelerates to the reference level, comparator 50 generates an error signal triggering one shot 56 to trigger memory means 60 to impress thereon a voltage proportional to a predetermined percentage of the instantaneous wheel speed at the time of deceleration to reference level and if, during the time period defined by the period of the one-shot pulse, wheel speed should drop to the memorized wheel speed memory 60 generates an output which activates controller 62 to release the brake pressure.
Patent ES-374114-A1 (ES)
Title: Improvements Relating to Colour Television Receivers
IPC: H04N9/20
Filed: 1969-12-01
Abstract: Relates to apparatus for increasing the proportion of either red or blue in the displayed picture of a tri-gun colour television tube while leaving at least the green substantially unaffected, said apparatus comprising means for altering the D.C. voltage level applied to the red or blue guns without affecting that applied to the green gun, said three guns being supplied by a common D.C. voltage generator. As shown in Fig. 1 the apparatus comprises a resistance network, terminal 10 being connected to the output of the high-tension D.C. voltage generator and terminals 23, 24 and 25 being connected to the first anodes of the green, red and blue guns respectively. Since the potentiometer 20 is arranged to have a very much higher resistance than that of resistors 12 and 13, movement of the slider of this potentiometer, for example to the left, will cause the potential at point A to increase very much more than the corresponding decrease at point C. Hence movement to the left causes the first anode potential of the red tube to increase without substantially affecting that of the green and blue tubes. Fig. 2 (not shown) illustrates an alternative arrangement in which a centre-tapped potentiometer is employed in place of potentiometer 20.

Patent ES-404697-A1 (ES)
Title: Method for injecting a gaseous reacting agent into a bath of molten metal
IPC: C21C5/34
Filed: 1972-07-08
Abstract: Method for injecting a gaseous reaction agent into a bath of molten metal by the use of a submerged nozzle to achieve the generation of a mass of very fine bubbles throughout a substantial portion of the bath. The bubbles mix and stir the bath to effect chemical homogeneity with a minimum amount of splashing and slopping of the molten metal and persist for a time sufficient to promote substantially complete reaction of the gas phase with the environmental fluid. By selecting a bubble diameter from a consideration of the desired gas flow rate and appropriate Reynolds number, the gas issuing into the molten bath will disperse into small bubbles of essentially constant diameter to maximize the gas-liquid interfacial area. Additionally, by controlling the pressure of the gas forced through the nozzle, the penetration of the fine bubbles into the bath can be controlled to achieve maximum stirring and optimum bubble retention time within the bath without damaging the refractory lining of the vessel containing the bath.

Title: Switching apparatus for single button hand microphone
IPC: G11B33/12
Filed: 1973-11-14
Abstract: A microphone switching apparatus for operating a recorder. The apparatus is incorporated into a hand microphone housing having a speaker, a microphone element, and an opening through which a control button for the apparatus extends. The apparatus is generally made up of a multi-region magnet movable along a path relative to a number of reed switches. Switching positions lie along the path which is defined by a slot in the apparatus frame corresponding to the opening in the housing. The control button is connected to a bolt which in turn is connected to the magnet. Movement of the button to the various switching positions will result in a combination of the reed switches being picked and dropped by the magnet. The picking and dropping of the reed switches will provide operating signals to the recorder. Also, maintaining the control button at two of the switching positions requires operator control in that if the operator releases the button, it will spring back to a previous position. Springs indirectly acting against the magnet cause the button to spring back to the previous position. As to the remaining positions, springs also indirectly act against the magnet, but latching means will maintain the button in place in the absence of operator control.

Patent ES-433604-A1 (ES)
Title: Control system for charging and discharging an electric storage heater
IPC: G05D23/19
Filed: 1975-01-07
Abstract: An electric storage heater assembly which is charged at night when energy rates are low and utilized during the day when the rates are higher. A fan unit is controlled by a thermostat to extract heat from the heater assembly. The previous days experience relative to the total time the fan operates is a measure of the heat to be stored during the off hours. An integrator with input and output switching elements activated by a clock controlled time switch is used in connection with a three position room thermostat, the positions being for high and low temperatures and neutral. The input switching element has positive and negative terminals and during day operation, the time the thermostat is in its low temperature position is summed through the positive terminal. The time the thermostat is in its high temperature position is subtracted from the accumulated value of the integrator through the negative terminal. The output switching element operates at night and controls the charging of heat storage assembly in accordance with the net accumulated value in the integrator which was determined by the experience incurred during the day.
