Title: Improvements in or relating to loudspeaker diaphragms and methods for the manufacture thereof
IPC: H04R7/12
Filed: 1961-02-14
Abstract: A method of making a loudspeaker diaphragm comprises the steps of impregnating a textile fabric with a stiffening agent forming the fabric to the required shape and then coating it with a thermosetting softening-agent-free lacquer. In one example the lacquer was made by preparing a 35% by weight solution in a mixture of methyl glycol acetate, toluene and ethyl acetate of the following mixture: 7 parts by weight of an ethoxyline resin and 3 parts by weight of an urea formaldehyde resin. In another example the lacquer was made by dissolving 10 parts by weight of polyvinylformal and 4 parts by weight of a cresolformaldehyde novolak in 86 parts by weight of xylene cresol 1:1. Specification 709,397 is referred to.ALSO:In a loudspeaker diaphragm (see Division H4) made of textile material both the sound radiating part and the peripheral supporting edge are impregnated with a thermosetting resin and after the resin has been set, the sound radiating part only is further coated with a synthetic thermosetting lacquer. A textile material, e.g. cotton, nylon, polyester fibre &c., having equal warp and weft is impregnated with a thermosetting resin, e.g. phenol-formaldehyde novolak and hexamethylene tetramine in an ethanol-water mixture. When the fabric is dry it is transferred to a mould where it is heated under pressure for a short time, i.e. 10 seconds, so as to produce for example a non-deformable conical diaphragm. The periphery of this diaphragm may be grooved and may be further impregnated with a plastic substance. In order to make the sound radiating part of the diaphragm impervious to air and resistant to insects, it is coated, by immersing, spraying or brushing with a lacquer and is then heated at about 200 DEG C. for 2-15 minutes. The lacquer should be of the type used for coating wires and examples are given, i.e. ethoxyline and urea formaldehyde resins in a solution of methyl glycol acetate, toluene and ethyl acetate, or by dissolving ten parts by weight of polyvinylformal and four parts by weight of a cresolformaldehyde novolak in 86 parts by weight of xylene cresol 1 : 1. Specification 709,397 is referred to.

Title: Improvement to safety and control systems for burner type heating installations
IPC: F23C99/00
Filed: 1965-07-08
Abstract: The starting winding 1b of a shaded pole single-phase motor 1 driving the fuel supply equipment of a burner (not shown) is in serieswith a delay tripping element 5 of a cut-out and with either contacts 2a which are opened by the action of a photo-conductive cell 3 detecting the flame of the burner or a parallel arrangement of a capacitor (11) and the photoconductive cell, Fig. 3 (not shown). When a thermostat 6 closes its contacts a relay 2 is energized and closes contacts 2a, 2b to start the motor and energize an ignition transformer 8 and open contacts 2c to take the photo-cell 3 out of circuit. After a predetermined time the tripping element 5 of the cut-out closes contacts 5b to connect the photo-cell across the relay 2 and if the burner has ignited the reduced resistance of the cell de-energizes the relay 2 so that the contacts 2a, 2b open to de-energize the starting winding and the ignition transformer and the contacts 2c close to keep the cell in circuit. The contacts 5b may be replaced by a thermistor. In a simplified circuit, Fig. 1 (not shown), the contacts 5b and 2c are omitted. In the circuit of Fig. 3 (not shown), the capacitor (11) has the same impedance as the starting winding (1b) of the motor and therefore the current in the starting winding is limited only by its resistance and by the resistance of the element (5) of the cut-out. In the presence of a burner flame, however, the photo-cell (3) short circuits the capacitor and the current in the starting winding drops.

Title: Process and apparatus for measuring the doubling time of a nuclear reactor
IPC: G21C17/14
Filed: 1966-10-08
Abstract: A proportional counter neutron detector is associated with a nuclear reactor and a digital circuit to evoluate the reactor doubling time defined by the expression where T D = doubling time, n = number of neutrons, A = reaction rate at time t = 0. The detector output passes to a multivibrator stage and then to consecutive stages of bi-stable multi-vibrators, the outputs of which are supplied by a logic unit and are then counted and compared with an electronic clock reference. Gamma ray discrimination is effected by a threshold analyzer. It is shown that with a large number of bi-stable multi-vibrators, the switching time of the bent bi-stable is approximately equal to the required value of T D .

Patent ES-337005-A1 (ES)
Title: A method of making passivated semiconductor devices
IPC: H01L23/29
Filed: 1967-02-18
Abstract: Passivated semiconductor devices are made by forming a planar PN junction parallel to the major surfaces of a wafer of semi-conductor, forming grooves in one major surface to cut through the PN junction and thus give a plurality of mesas, filling the grooves with passivating material and attaching electrodes the exposed portions of the mesas. The major surface which is not grooved is fixed to a conductive substrate. A p+ type substrate 22 of Si, has semi-conductor wafer of Si, Ge or GaAs containing a PN junction joined thereto by a layer 24 of Cr, Ni, Ta, W, Nb, Mg, Ag, Co, Cu or Ti. The wafer and substrate are joined by hot pressing in an induction furnace between carbon blocks. Grooves are then cut in the wafer to give mesa portions 40, the sides of which are coated with SiO 2 44 and then the grooves filled with glass 46. The exposed surfaces of the mesas and the substrate are coated with electroless nickel and then solder applied. Electrodes are applied and soldered in place using a carbon jig (Fig. 8, not shown). The structure may then be cut vertically into a number of separate devices. In a modification a horizontal cut may be made prior to applying the lower electrode, to cut away the connecting substrate portions. Instead of joining individual electrodes in the array of devices, a plurality of devices may be joined by one conductive strip for use in integrated circuits.
Patent ES-344863-A1 (ES)
Title: Time delay control circuit
IPC: H03K5/08
Filed: 1967-09-08
Abstract: A timing circuit connected between emitter and base of a unijunction transistor comprises, in series, a capacitor and a variable platform voltage source which does not charge the capacitor whereby the delay before charging of the capacitor causes the transistor to fire depends upon the platform height. With this arrangement the timing may be immediately responsive to variation of the platform height. As shown in Fig. 2, the variable platform source 38 is connected in series with the timing capacitor 34 which is charged through resistor 46 or a constant current source. When the combined voltage is sufficient the unijunction transistor conducts, firing a thyristor 18 and also discharging capacitor 34 through diode 50. The pulses repeat at a rate depending upon the platform voltage. Diode 48 isolates the platform voltage source from the discharge current path and a clamp 44 for the source is also provided. The discharge current of capacitor 34 is supplemented by current from an additional capacitor 52 to ensure firing of the thyristor. The voltage across the additional capacitor follows a little behind the timing capacitor voltage due to the action of the emitter follower 60 and is isolated from the emitter of the unijunction transistor by a diode 58 until discharge has been initiated by the voltage across 34. In Fig. 1 (not shown), the additional capacitor 52 is charged at the beginning of the timing period to a fixed voltage determined by a Zener diode (56) and does not follow the timing capacitor voltage. In Fig. 3, variations in the timing period with the breakdown voltage level of the unijunction transistor are avoided by comparing a reference voltage 80 in the emitter circuit of a transistor 60 with the combined timing and platform voltage applied to the base. When the latter reaches a value such that the transistor 60 conducts the potential of the base of the unijunction transistor is thereby lowered and discharge through the emitter of the unijunction transistor is initiated. The thyristors are connected between a three-phase supply 70 and load terminals such as 75, 77. The circuit may be used in a tetroactive control system.

As shown the exhaust duct 17 and the air supply duct 16 communicate with each other through a duct 20 including a blower 21. In a modification the duct 20 and blower 21 are on the side of the air preheater 18 adjacent a blower 19. In another modification the blower 21 is omitted and the supply of combustion gases to the air supply duct is controlled by valves. In a further modification an injector is employed. Other modifications are described.

Title: Polybutadiene and Process Therefor
IPC: C08F136/06
Filed: 1967-10-03
Abstract: Homopolymers of butadiene with a Parallel- Plate Recovery value of at least 0À75 mm. are made by polymerizing 1,3-butadiene in the presence of a lithium hydrocarbon catalyst, e.g. butyl lithium, and at a peak temperature of at least 212 F.

A liquid inert to the catalyst may optionally be present during polymerization.
Patent ES-346240-A1 (ES)
Title: Improvements in or relating to gear control mechanisms
IPC: F15B21/00
Filed: 1967-10-19
Abstract: In a motor-vehicle gear-change control mechanism having a manual selection lever 9 to control power actuation of the change-speed gear by pneumatic or hydraulic servomotors (not shown), the lever 9 is constantly biased towards neutral by spring-loaded plungers 10, 11 which are manually overridden for gear selection the positions of which may be held, against the neutral seeking plungers 11, manually and/or by a fluid pressure operated spring-loaded piston 2 and detent plunger 5 which effectively engages a quadrant 6 of the lever 9 only whilst sufficient air pressure exists in the detent valve cylinder 1 connected via a pressure sensing valve 15 to the gear-box accumulator 14, the accumulator 14 being connected via a non- return valve 13 and divertor valve 12 to the vehicle braking system (not shown) and via a pressure-reducing valve 16 to the gear control servomotors (not shown). Thus the arrangement, in which the manual selection is combined with wholly pneumatic or hydraulic or with a combination of electric, pneumatic or hydraulic means e.g. either fluid pressure control direct via the manual gear selector, or, via electrically operated valves mounted independently from the servomotors and operated by electrical signals from the selector, provides an automatic neutral seeking selector operative whenever the gear controlling fluid pressure falls below that required to maintain gear engagement.

Title: Voltage stabilising circuit
IPC: H04N3/185
Filed: 1968-02-01
Abstract: In an E.H.T. stabilizing circuit, for a cathoderay tube, of the type including rectification of the output of a controllable pulse-operated power stage, the control voltage is derived by combining with opposite polarity a first voltage produced by rectification of the rear portion of pulses derived from the power stage and a second voltage derived by rectification of the front portion of said pulses. As shown, the pulseoperated power stage 27 is coupled by means not shown, to a transformer, the output of which is rectified at 31 to produce the E.H.T. voltage. A negative pulse between terminals 1 and 2 of the transformer is differentiated at 28, the positive portion of which (corresponding to the rear edge of the pulse) is rectified at 4 and combined with the output of a rectifier 8, operative on the front portion of the pulse. The combined control voltage (adjustable at 12) is superimposed on a ripple voltage (derived from a capacitive divider 15, 32) and passed via a transistor 16 and rectifier 20 to the grid of the power tube 27 where it is further combined with the drive waveform supplied via capacitor 25 and flyback pulses supplied via capacitor 22. The voltage derived from the rear portion of the pulses acts to stabilize the E.H.T. voltage against supply variations whilst that derived from the front portion of the pulses compensates for the internal impedance of the E.H.T. circuit.

Patent ES-361262-A1 (ES)
Title: Spark ignition systems for internal combustion engines
IPC: F02P3/04
Filed: 1968-11-30
Abstract: An ignition system comprises an oscillator VT1, a spark producing circuit 13, 14, VT4 which on receiving an input from the oscillator produces a spark at a plug 22 of the engine, means coupling the oscillator to the spark producing circuit and means (not shown) driven by the engine for controlling the oscillator to determine the instants at which sparks are produced. The oscillator is provided with both positive and negative feedback L2, L1 so that when no spark is required the oscillator does not oscillate. The means driven by the engine serves to increase the positive feedback when a spark is required and so cause the oscillator to oscillate. Each spark is produced when the switching device VT4 is turned off and a monostable circuit driven by the output from the oscillator serves when in its unstable state to turn the switching device off. The oscillator used starts suddenly when the coupling between the coils L2 and L3 is increased. The spark is produced substantially instantaneously when the ferrite rod (not shown) passed over the core of the coils.
