Title: Improvements in or relating to electric motor control systems
IPC: B63H23/24
Filed: 1922-03-08
Abstract: 194,248. Cachemaille, A. S., (Westinghouse Electric & Manufacturing Co.). March 8, 1922. Master control systems; controllers, interlocking.-A group of switches for controlling motors such as are employed in the propulsion of submarines, are remotely controlled by a master drum controller and have an alternative manual control interlocked with the master control. Fig. 1 shows the operation of one of the switches. A movable contact 153 is linked to the piston of a pneumatic cylinder 163 which receives air through a valve 166 opened by energization of a magnet 167. This and the other magnets of the group are electrically connected to the master controller. Alternative mechanical actuation is effected by a shaft 175 fitted with cams 52 which act through levers 172, 171 and springs 174 to raise the magnet armatures from below. The cam shaft is geared to a hand-wheel 176 which tends to be locked by a stop-pin on a lever 180 urged by a compression spring 181 and has to 'be freed by moving a changeover switch 66 to the position shown. In this position of the change-over switch, the motor field circuits are excited independently of the master-control system, and the magnet coils become inoperative. Correct order of operation among the various switches of the set is ensured by further mechanical interlocks comprising suitably bent levers 201, 202, Fig. 11, projecting into the path of extension pieces 98 attached to the piston rods of the respective switches 153. When a switch is closed, the corresponding lever is thereby moved to block one of the cam-shaft transmission-levers 171 against movement.

Title: Improvements in and relating to ultra short wave modulated carrier wave radio communication systems
IPC: H03C7/02
Filed: 1933-01-17
Abstract: 413,646. Wireless transmitting systems. MARCONI'S WIRELESS TELEGRAPH CO., Ltd., Marconi House, Strand, and LINSELL, A. A., 43, West Hill, Sydenham, both in London. Jan. 17, 1933, No. 1553. [Class 40 (v).] Ultra-short radio waves, of the order of 60 cm. wave-length, are modulated by one or more absorbing conductors placed in the path of the radiated wave the resistance of the conductors being varied by the modulating signal. The absorbing conductor 3, Fig. 2, is placed at a distance greater than a wave-length from the radiating dipole 1. At its centre or at two or more points in its length, a valve is connected so that its anode-filament path completes the circuit of the conductor. The resistance of the valve is varied by a microphone M coupled to its grid circuit, which thus causes the conductor to absorb varying amounts of energy from the passing wave. The valve capacity is prevented from shunting the valve resistance by connecting across the valve a non- radiating line 8 in series with a blocking- condenser 9. The conductors 3 may each comprise several parallel rods. As shown in Fig. 6, the modulating-valve 4 has a fixed bias on its grid, and the signal voltage, amplified by a valve 10, is applied to the anode circuit, either by a transformer 11 or by a choke coil. Several conductors 3, 3<1>, Fig. 5, may be arranged at different distances from the dipole radiator 1, and the signal may vary the resistance of all the valves 4, 4<1> jointly.

Abstract: 469,444. Wireless receiving systems. TELEPHONE MANUFACTURING CO., Ltd., and PADDLE, L. H. Jan. 21, 1936, Nos. 1917 and 18119. [Class 40 (v)] In a system using a receiver as claimed in Specification 450,150, in which the intermediate frequency amplifier is tuned to the frequency of the local oscillator, the gain of the receiver is controlled automatically by a pilot wave, which may be a modulation on the carrier wave and may itself be modulated by the signal before it is used to modulate the carrier wave. In Fig. 3, the input from aerial A is applied to the anode circuits of a pair of valves V1, V2, local oscillations from OSC being applied to the grids, and resistance R1 adjusted so that the valves nearly oscillate, super-regenerative operation resulting. The local oscillations are modulated by the currents of speech and pilot frequencies, and the upper or lower modulation products are filtered out and passed to a variable-mu valve V3 acting as an intermediate frequency amplifier, part of the output being rectified at V4 to control the gain of V3. In the system shown in Fig. 4, in which gain is controlled by the component of pilot frequency, signals from the aerial A and local oscillations from OSC, amplified by a variablemu valve V6, are supplied to the anode circuits of the first detector valves V1, V2, feeding the intermediate-frequency amplifier V3. The output from this passes to a diode V7, the load resistance R3 of which supplies modulations of speech and pilot frequencies to the amplifier V5, speech frequencies passing through a filter BP1 to the loud-speaker and the pilot frequency through a filter BP2 to a further rectifier V8, the load resistance R4 of which supplies gain control potential to the valves V3, V6. In order to prevent maximum gain with no signal input, the direct-current output of diode V7 is provided with a potentiometer R5 from which a small negative voltage is impressed on the anode of the rectifier V8, thus limiting the minimum bias applied to the valves V3, V6. The potentiometer R5 may be replaced by a battery. Specification 450,967 also is referred to.

Title: Improved process and apparatus for working glass bodies
IPC: C03B23/207
Filed: 1939-01-23
Abstract: 524,126. Electric heating; incandescent electric lamps. CORNING GLASS WORKS. Jan. 23, 1939, No. 2297. Convention date, Feb. 19. 1938. [Classes 39 (ii) and 39 (iii)] [Also in Group XXIII] Relates to a process for working glass bodies wh:le the glass is hard, either for joining two parts or for separation into a number of parts. According to the invention, a body and a source of electricity are rotated relatively to one another while the place to be worked is subjected to heating, the working heat being applied by passing a current of electricity through the glass along a predetermined path defined by the relative rotation of the body and the source of electricity. Figs. 3 and 4 show an apparatus for sealing an electric lamp bulb 11 to a pressed glass base 12. The parts are held by chucks 13, 14 respectively, which are rotated in unison with one another and can be moved to and from one another. The heating-device consists of a pair of metal rod electrodes 37 adjustably held in insulated terminals. A spark discharge between the electrodes along the surface of the glass forms a hot stripe and renders the glass conductive. This heating may be supplemented by a zone heater consisting of a resistance band 47 mounted on a block 48 of insulation. In operation, the glass parts while rotating have their edges brought close together, and these edges are subjected to gentle heating by the resistance 47 to prevent fractures of the glass. The glass is then subjected to intense heating generated locally by the dicharge from the electrodes 37 which are connected to a high voltage source of either high or low frequency. As the glass melts, the edges of the parts are brought into contact and sealed. The heater 47 may be replaced by a gas-burner 53, Fig. 5, with a fishtail tip, and the electrodes 37 replaced by needleflame burners 55 which are fed with oxyhydrogen. This arrangement is more suitable when the device is used for cracking-off or for cutting tumblers or cylinders. The burners 53 are mounted in insulated holders and are connected to a suitable source of high potential. When high frequency potentials are used for the spark discharge, a second potential of lower frequency voltage may be connected to the electrodes 37 to supply the bulk of the heating current. An intermediate electrode may be used also to localise the discharge. Capacity and inductance may be included in the circuit of the electrodes 37 to form a resonant circuit, and an air blast across the electrodes, or an electromagnetic field, may be used to quench the spark.
