Title: Improvements in thermionic valves
IPC: H01J7/24
Filed: 1938-03-29
Abstract: 513,655. Thermionic valves. STANDARD TELEPHONES & CABLES, Ltd., and GIBSON, W. T. March 29, 1938, No. 9594. [Class 39 (i)] Overheating of insulating parts of high power ultrashort wave transmitting valves due to high dielectric loss is prevented by cooling those parts by circulating fluid of high electrical resistance. The valve B may be of the kind described in Specification 504,123 and has an anode A forming part of the envelope, the glass portion B of which is cemented to a metallic ring C to which the grid electrode is connected, The valve is enclosed in a cooling jacket comprising a tube E of glass or "Bakelite" (R.T.M.) with metal end plates F secured by insulating strainers I and wing nuts K. The cooling liquid which may be distilled water or oil, is admitted at the lower end to pass first over the anode A and then the bulb B ; baflles may be provided to guide the flow along the anode surface, Fig. 1 (not shown). The end plates F constitute the connections to the grid and anode of the valve, the latter being supported by a resilient member M. Specification 349,719 also is referred to.

Title: Improvements in and relating to radio receiving apparatus
IPC: H03D7/08
Filed: 1932-04-04
Abstract: 388,235. Valve circuits for wireless reception. DIAZ, 1., 42, Rue Charles Laffitte, Neuilly-sur-Seine, France. April 4, 1932, No. 9689. Convention date, April 3, 1931. [Class 40 (v).] In order to adapt a receiving-set for the reception of wave-lengths outside its tuning- range, a frequency-changing device taking its supply voltages from the set is interposed between the aerial and the set. The resulting frequency which is applied to the set is intermediate between the incoming frequency and the frequency of the local oscillator. The frequency-changing device comprises a valve 6 oscillating by virtue of its plate circuit being coupled to a tuned grid circuit 7, and also receiving the incoming oscillation by virtue of a coupling 5 between its grid circuit and the aerial. The aerial coupling 5 is nearer the grid, and the oscillator circuit 7 nearer the cathode, of the valve -6. The resultant frequency appears in a tuned plate circuit 8 and is transferred either directly or by an inductive coupling to the input terminals 9, 10 of the receiving-set 3. A switch 2 enables the aerial 1 to be connected either to the frequencychanger or direct to the receiving-set 3, and when in the latter position is arranged to disconnect the tuned plate circuit 8 from the terminals 9, 10 and to interrupt the plate supply circuit of the valve 6. To avoid the necessitv for additional supply sources for the valve 6, an adaptor socket is fitted in one of the valve sockets of the receiver, and leads taken from the adaptor plate and heater terminals. The plate lead preferably passes to the switch 2, but the heater leads may pass direct to the heater terminals of the valve 6. Frequencies within the range of the set 3 are excluded from the frequency-changer input by a choke 4 or a capacity, according as the frequency is being raised or lowered. The input circuit 5 and the local oscillator circuit 7 may be jointly tunable over a range of frequencies, the resultant frequency being maintained constant.

Title: Charge Control Apparatus
IPC: G03G15/02
Filed: 1967-03-01
Abstract: 1,170,472. Electrostatically charging xerographic plates. RANK XEROX Ltd. March 1, 1967 [March 2, 1966], No.9801/67. Heading G2H. A xerographic plate 14, moved step-by-step relatively to a corona charging device 17, receives a substantially uniform charge independently of the dwell times of the plate. The charging is controlled by a control circuit having a pulse generator 3 which selectively generates one of a plurality of pulse trains having repetition rates proportional to the stepping intervals of the plate. The charging device 17 is a scorotron having an earthed conductive shield 18, a plurality of corona emitting wires 19, and a screen electrode 20. The potential of electrodes 20 regulates charging. This potential is maintained at a high level during plate movement and at a lower level during a dwell period of plate 14 by a triode 29. When triode 29 conducts for a period corresponding to a dwell period the screen electrode voltage is lowered. A transistor 23 conducts upon resetting of a flip-flop 8 to cause triode to conduct and is non-conducting when flipflop is in set condition. The plate 14 is driven step-by-step by a motor 12 under the control of a control circuit 11 fed by power pulse amplifier 5 and brake pulse amplifier 10. The amplifiers are fed with pulses of appropriate duration through a circuit having flip-flops 4, 7, and 8 and multi-vibrators 6 and 9. In a modification, the plate 14 is stationary and the scorotron 17 is moved in steps. Also, the corona voltage may be pulsed and the screen voltages maintained constant.

Title: Apparatus for grouping cigarettes and like articles for packeting
IPC: B65B19/10
Filed: 1929-03-27
Abstract: 312,341. Universelle Cigarettenmaschinen-Fabrik J. C. M³ller & Co. May 25, 1928, [Convention date]. Packeting cigarettes &c. in boxes.-Cigarettes and like articles are formed into groups of definite numbers for introduction into a packet or box, and, in order to obviate the effect of a gap in the cigarettes being fed towards the grouping station, means are provided to ensure that each group contains the correct number. The cigarettes z, Fig. 1, are fed separately into pockets 1 on an endless band 2 passing over a pulley 3, and are delivered over a bridge 4 against a stop 8 in a collecting channel 7. The bridge is pivoted at 9, and a downward projection 10 constitutes the armature of an electromagnet 11, which normally holds it in the position shown in full lines, against the action of a spring 12. The contact for the circuit 16, 17 of the electromagnet is formed by an insulated pin 19 axially disposed with relation to a toothed counting wheel 20. The pin extends between stationary discs 14, 15 to which the conductors 16, 17 are connected. The toothed wheel, the number of inter-dental spaces on which is greater than that of cigarettes to a group, rotates freely on its spindle 21 when actuated to do so by the cigarettes on the band 1 passing over it, and keeps the circuit closed until the pin 19 comes opposite a recess 23 in the disc 15. The circuit is then broken, and the bridge 4, under the action of the spring 12, moves into the position shown in broken lines, and deflects any excess of cigarettes from the group formed in the guide 7. In the event of one of the pockets on the band 1 not carrying a cigarette, the correct number is still fed to the group, as the wheel 20 is only advanced when a cigarette is present.

Title: Improvements in or relating to arrangements for filling containers with solid material
IPC: B65G69/02
Filed: 1956-03-29
Abstract: 822,347. Container-filling machines. CROUCHER, A. H. March 26, 1957 [March 29, 1956], No. 9847/56. Class 94(1). [Also in Groups XVIII and XXX] A machine for filling tubs with coal comprises an immersion vibrator which is lowered into each tub to settle its contents during the filling operation. The coal is fed by a belt conveyer (not shown) to two weighing hoppers 18 at either side of the filling station, each hopper being supported by hydraulic cylinders 19 connected to a weighing valve 20 and being tiltable to discharge its contents by a hydraulic ram 17 controlled by a valve 16. When the required weight of coal has been fed into one of the hoppers, the associated valve 20 operates a switch 29 to start a motor 25 driving a cam-shaft 23. A cam 23a on the shaft then operates a valve 6 to cause compressed air to be supplied to the right-hand ends of cylinders 9 which operate a pusher 10 to move a tub into the filling position and a pneumatic vibrator 14 is lowered into the tub under the control of a cam 10a on the pusher. A cam 23d or e then operates the appropriate valve 16 to cause the associated ram 17 to tilt the hopper and discharge its contents into the tub, a cam 23b operates valves 8 to switch the supply of compressed air to the left-hand end of the cylinders 9 so that the pusher 10 is withdrawn and the vibrator raised, and a cam 23c operates the switch 29 to stop the motor 25.

Title: Device for distant transmission of the angular displacement and force between camshaft and follow-up shaft
Inventor: DIMITROV DIMITR CONEV
IPC: G08C19/38
Filed: 1988-01-27
Abstract: Improved accuracy of transmitting the turn angle and the force between the master and slave shafts of a manipulator are ensured with the torques of the corresponding synchronous motors exhibiting equal orientation of their rotors magnetic fields. The shafts of the two motors are kinematically connected to the master and slave shafts and to position transducers which feed the setter of the relevant stators magnetic field amplitude. The output of the setter is applied to the corresponding windings of the master and slave motor which are linked in opposition to each other, while its control input is tied to the setter of field orientation of stators of the master and slave synchronous motors. The static error due to the torques of the operator and load are eliminated by orienting the stator fields of the synchronous motors perpendicularly to the fields of their rotors. - The shafts (3,4) of the master and slave synchronous motors (1,2) are linked to the relevant shafts (5,6) and to position transducers (9,10) which drive the setter (11). The latter determines the amplitude of the magnetic field of stators of the master and slave motors, and its output is tied to the control input of the current shaper for the windings of the master and slave synchronous motors while its setting input is fed from the setter (15) of stators magnetic fields orientation of the master and slave synchronous motors.
