Filed: 1960-03-24
Abstract: 922,491. Thermistors. COMPAGNIE GENERALE DE TELEGRAPHIE SANS FIL. March 24, 1960 [April 3, 1959], No. 10515/60. Class 37. A thermistor material comprises oxides of manganese and nickel and an amount of lead oxide equal to from 0.1 to 10% by weight of all the other constituents combined. A typical material is made by grinding together in an aqueous medium weighed amounts of oxides of manganese, nickel, and perhaps oxides of cobalt and/or copper, with lead oxide or one or more lead salts capable of calcining to the oxide, drying, sieving, mixing with a 10% solution of polyvinyl alcohol, sieving, moulding under pressure and calcining and fritting at 1260‹ C. Alternatively the oxides may be prefritted by heating at 600-1200‹ C. before the lead oxide is added. The presence of the lead oxide in the composition in addition to reducing the resistivity of the product without significantly affecting its temperature coefficient and reducing the effect of variations in the fritting temperature, results in a less porous body. Examples of specific compositions are given.

Title: Improvements in or relating to automatic radio tuning circuits
IPC: H03J7/30
Filed: 1952-04-30
Abstract: 759,474. Electric control systems. STANDARD TELEPHONES & CABLES, Ltd. Jan. 30, 1953 [April 30, 1952], No. 10906/52. Class 40(1) [Also in Group XL(c)] An automatic lining arrangement for a crystal controlled oscillator comprises a crystal selector switch (not shown) which when rotated to select a new crystal starts a motor M which drives the tuning of an associated circuit (not shown). The output of the circuit is rectified to provide a negative control signal which is applied through terminal T1 to the control grid of valve V. As resonance is approached the signal becomes more negative reducing the valve current and thus causing the anode to become more positive. This causes a current to flow into a capacitor C4, moving contact RA1 of a polarized relay RA to the left. Immediately the tuning passes beyond resonance the anode potential begins to fall and the condenser to discharge, so that contact RA1 then moves to the right. This operates a relay RB whose forward contacts RB1 break the circuit of the motor M and clutch CL and operate a brake, while the back contacts of RB1 make the circuit of a relay RC to cause contact RC1 to short circuit the input to the valve. Contact RB2 provides a holding circuit for relay RB. When the crystal selector switch is moved to a new position switches S1 and S2 which are ganged with it move also. Switch S2 breaks the holding circuit of relay RB to restart the tuning motor while switch S1 maintains relay RC operated during the movement of the switch since the relay is of the slow to release type and the relay circuit is broken for a substantial time only when switch S2 comes to rest. A thermal delay switch T.D.S prevents the valve taking current until the apparatus being tuned has warmed up. According to the Provisional Specification a rectifier may be connected between the valve anode and the capacitor C4 and a separate discharge resistance connected in parallel with the capacitor and relay. In addition contact RC1 is connected across the cathode bias resistor R3.

A yarn winding machine provided with a suction device comprising a tubular member 15 connected at 17 to a supply of gas under pressure and opening into an exhaust tube 16 at the other end, a notch being provided (see Fig. 2) in the wall of the member 15 crossways to the axis thereof, is characterised in that the notch extends in the wall of the member 15 at least to the axis thereof and that thread guides 20 are provided on both sides of the notch to aid guiding a loop of yarn there-into. In use, the yarn, during winding runs direct from the traverse button 14 on to the package, but upon doffing, the operator margins the device 15, swings the traverse frame 10 until the guide occupies the doffed position, Fig. 1, and brings the thread between package and guide downwards so that it extends across the notch in the device 15 and beneath the guides 20. He now cuts the yarn between the guides 20 and the bobbin and he removes the running yarn, which is being sucked to waste, from beneath one guide 20, to eliminate friction losses. The full package is now removed by the operator and he lifts the running yarn between the device 15 and the traverse guide 14 so that it runs through the guide 21 and over the roller 22. The yarn is now running along the full-line path of Fig. 1. An empty cone is now placed on the spindle 11 which grips the yarn and effects severance by a cutter 23, the severed end being sucked away by the device 15. The handle 21a is then manipulated to release the yarn from the guide 21 and the frame 10 is moved into its normal winding position. U.S.A. Specification 2,706,089 is referred to.

[Also in Division H3] In a circuit of the type in which a D.C. signal is modulated on a carrier, amplified and then applied to a phase-sensitive device such as an electric motor, the modulator employs varicap diodes and modulation is effected upon low and high frequency carriers. The higher frequency can be of optimum value for the modulator and the low frequency optimum for the amplifier. As shown, the signal U 1  and lower frequency U 3  are applied to one diagonal of the modulator bridge and the high frequency to the others. The resulting double modulated high frequency is amplified by transistor 20, demodulated at 29 to produce the signal modulated lower frequency and this is reflexed to the base for further amplification before selection at 35 and application to a motor 33. When its input signal is zero only a doubled low frequency appears at the output and this is rejected by the output circuit 35. In an alternative modulator, Fig. 3, the high frequency is applied across one diagonal c, d and the low frequency in series between the diodes. In each circuit a balancing potentiometer may be provided.

Abstract: 438,195. Servomotor control systems. REAVELL & CO., Ltd., and HUMBY, A. J. D., Ranelagh Works, Ipswich. April 13, 1934, No. 11193. [Class 135] Apparatus for regulating physical values such as temperature, humidity, density, water level, &c., where only very limited power is available for operating the regulator comprises means for producing operation of an all electric transmission gear of the kind employed in Specification 265,012, [Class 40 (i)], with which is combined a relay adapted to operate means for producing a modification of the prevailing conditions. For controlling the temperature of a stream of fluid in a duct 1 a valve 4 is controlled to vary the admission of a cooling fluid. A thermocouple 3 produces a very small current in an electric coil 7 which moves a contact pointer 6 to make contact with either contact 15 or 16 of another pointer member 8 which closes either the forward or reverse circuit of a motor 13. The operation of the motor 13 alters a resistance 17 in an electric circuit 18 and therefore the current flowing in the said circuit, which current passes through a follow-up coil 9 attached to the contact pointer 8 which brings this pointer into a corresponding position to that of the pointer 6, i.e. a position where the pointer 6 is midway between the contacts 15, 16 of the pointer 8, so that the motor circuit is broken and the motor stops. Thus the position of the contact pointers 6, 8 and the current flowing in the circuit 18 are functions of the temperature in the duct 1. The current in the circuit 18 is utilized to operate a core 20 of a solenoid 19 which operates a relay in the form of a pivoted jet pipe 21 supplied with fluid under pressure to operate a servomotor 5 connected to the valve 4.
