Title: Improvements in or relating to electrical oscillation generator arrangements
IPC: H03K5/00
Filed: 1935-09-24
Abstract: 463,255. Automatic control systems. MARCONI'S WIRELESS TELEGRAPH CO., Ltd. Sept.. 24, 1935, No. 26470. Convention date, Oct. 18, 1934. [Class 38 (iv)] [Also in Groups XL and XXXVI] Phase displacement.-In an electrical frequency-dividing impulse generator, for use in securing scanning control and synchronization in television and like apparatus, comprising a chain of multi-vibrator units in cascade each adapted to produce impulses at a frequency which decreases by integral fractions along the chain, the output impulses of the last unit are synchronized in phase and frequency with a control source, e.g. the electric supply mains, by combining and rectifying them and utilizing the resultant voltage to adjust the frequency of the primary unit of the chain. As shown, the chain comprises four multivibrators A, B, C, D operating respectively at frequencies of 20580, 2940, 420 and 60 cycles, the first unit A being free running and the other units B, C, D being locked in frequency by the preceding unit at one-seventh of the frequency of that unit. Each unit comprises a triode valve T1 and a valve T2 with two or more grids (preferably a pentode) and these may be arranged in a single envelope. Each valve has grid and anode resistances and the anode of each valve is cross-coupled by equal capacities to the control grid of the other, the outer grid of the valve T2 serving as an anode. Output is taken from each unit 'by a plate P3 connected to the positive supply lead through a resistance R, which also lies in the plate supply lead for the anodes of the next unit in the chain and applies synchronizing impulses to that unit. The 60 cycle output of the last stage D is kept in phase with current from supply mains by applying the output impulses to the grid of a valve 65, which gives rise to a saw-tooth voltage across the condenser 80 in its plate circuit. This voltage is combined with a sinusoidal voltage derived from supply mains through a transformer 75 and a phase-adjusting network comprising a variable resistance 81 and a condenser 83. The combined voltage is rectified in a valve 60 and is applied through a smoothing-filter 63 to the grid of the tetrode valve T2 in stage A. Any alteration of phase relation between the impulse output from the stage D and the supply mains alters the rectified current in the output of the valve 60 and so varies the voltage on the grid of the valve T2. The frequency generated in the stage A is thus adjusted and the original phase of the output from stage D is restored.

Title: Apparatus for marking characters on the periphery of round objects
IPC: B41F17/18
Filed: 1951-11-13
Abstract: 702,098. Printing on cylindrical surfaces. BRITISH THOMSON-HOUSTON CO., Ltd. Nov. 13, 1951 [Nov. 13, 1950], No. 26559/51. Class 100 (2) A device for marking characters on the periphery of round objects, e.g. the bases of small lamp bulbs comprises a pair of arms 10, 11 carrying gripping means at their forward ends, means for advancing the arms towards a work station at which bulbs are periodically presented, means for actuating the arms to close the gripping means on the base of the bulb, means for sliding the arms with respect to each other to roll the base between them, and a marking stamp 46 adapted to print on the base during the rolling. The arms 10, 11 are of square section and slidably mounted in guides 12, 13 each pivotally mounted on a block 14 and formed with gear teeth 15, 16 so that their swinging movements are equal. A spring 26 urges the arms together and a latch 27, pivoted to guide 13 and having a shoulder engageable with a peg 29 on guide 12, maintains the arms in the open position, Fig. 6a. The block 14 is slidable on a base to which are fixed a pair of rollers 37, 38 co-operating with the ends of the arms. At the other end arm 10 carries a pair of rollers 41 and arm 11 carries a serrated gripping plate 43 resiliently mounted by springs 44 on adjusting screws. The printing type 46 is carried on a spring loaded lever pivoted on the underside of arm 11. The operation of the device is as follows : From the initial position, Fig. 6a, the block 14 is displaced towards the bulb 1 which is held in the work station by a spring clip; this displacement causes the latch 27 to be tripped by engagement with a fixed peg 30 so that the arms 10, 11 are closed to gripping position by spring 26 as shown in Fig. 6c; the block 14 is then moved away from the work station carrying the bulb with it ; this movement first causes the end of arm 10 to abut roller 37, the arm 10 being caused to slide through guide 12 against the action of a spring housed in a longitudinal bore of the arm ; the relative movement betwen the arms causes rolling and printing of the base of the bulb as seen in Fig. 6e ; further movement causes engagement between the inclined rear end 39 of arm 11 and roller 38 so as to swing the arms anart and release the bulb which drops into a delivery chute ; the latch assumes its operative position again and the block 14 is returned to the initial position shown in Fig. 6a. Inking apparatus.-The type 46 is inked bv a pad 53 pivotally carried on a sliding cross member 54 actuated by hand or automatically towards the type during the rest period of the device. A projecting member fixed under the arm 11 engages an arm on the pivot 57 of the pad 53 to swing the pad vertically against the type. Ink is supplied to the pad by a stationary spring- loaded roller transferring ink from a disc to which it is fed. e.g. by dripping. The disc may be revolved by a pawl and ratchet actuated by the oscillation of the slider 54.

Filed: 1928-09-17
Abstract: 297,327. Bothe, O. Sept. 17, 1927, [Convention date]. Public address systems; loud-speakers. - An apparatus which is particularly intended for advertising purposes, and which comprises means for recording sound magnetically on a steel wire or strip, and for reproducing the recorded sound, using a valve amplifier operating a loudspeaker, can also be used for direct reproduction, by the loud-speaker, of words spoken into a microphone. For use in shop windows, a loud-speaker is employed which utilizes the window pane as a diaphragm. Fig. 6 is a circuit diagram, showing how a microphone 55 may be connected either to a sound-recording magnet 24 or to the input side of a valve system by which a loud-speaker 53 is operated. With the switch 34 in a position indicated at III, words spoken into the microphone can be directly reproduced by the loud-speaker. The loudspeaker, as shown in Fig. 4, comprises a heavy body 62 suspended by a rod 63 so that. a rod 64, adjustably connected to the polarized armature 58, bears against a window-pane 66. Vibrations are thus transmitted to the glass, which acts as a diaphragm. An iron yoke 60 is pre-magnetized by a coil 61, and the speech currents pass through a coil 59.

Title: Improvements in or relating to motor operated valves
IPC: F16K31/122
Filed: 1936-03-05
Abstract: 471,580. Valves. PAYNE, M., and BRITISH THERMOSTAT CO., Ltd. March 5, 1936, No. 26673. Divided out of 471,540. [Classes 69 (ii) and 135] The invention relates to apparatus for operating a spring or weight-loaded main valve 3 by the hydrostatic pressure produced by a motor-driven pump 5 in a working chamber 1, in which a floating piston or diaphragm 7 is interposed between the pump and the working chamber, and controls a release valve 9 which opens to allow fluid to escape from the working chamber when the pump motor is switched off. According to the invention the floating piston or diaphragm has a permanently open restricted passage 11a enabling the pressures on the two sides of the piston or diaphragm to equalize when the fluid flow ceases due to stoppage of the pump or due to the working chamber having expanded to its maximum volume. As shown, the valve 3 is opened against a spring 4 by hydrostatic pressure on a piston 2. However, the valve may be closed by the hydrostatic pressure and the piston 2 may be replaced by an equivalent device such as a bellows. The pump delivery pressure forces the piston 7 downwardly in its chamber 6 against a spring 8 until the valve 9 closes a conduit 11 leading back to the pump supply 12. After the piston 2 has moved upwardly to its fullest extent, the pressures on the two sides of the piston 7 tend to equalize and the valve 9 moves to maintain the flow back to the supply 12 constant, depending on the size of the passage 11a and the strength of the spring 8.

Filed: 1956-08-31
Abstract: 798,050. Multiplex systems. SIEMENS & HALSKE AKT.-GES. Aug. 31, 1956, No. 26715/56. Class 40 (4). A cable includes, in addition to a plurality of coaxial lines, further lines, some at least of which are symmetrical (i.e. balanced to earth) at least one pair of such further lines being used for a two-wire carrier system, i.e. a system in which the go and return signals are transmitted in different frequency ranges over the same pair of wires. These two-wire carrier systems are used to provide communication between localities sited along the main coaxial route. Normal low-frequency lines (with loading coils removed) may prove suitable for this purpose in some instances. The attenuations of the further lines may be such that their circuits may be repeated at the same stations as the coaxial cable circuits. Thus, e.g., every second repeater station for the coaxial cable may also contain repeaters for the two-wire carrier systems. The use of separate go and return pairs for the further circuits is mentioned, but dismissed as being less economic in lines than the system proposed.

Title: Improvements in and relating to apparatus for cleaning the nozzle bodies of the injectors of compression ignition internal combustion engines
Inventor: TAYLOR CECIL ISAAC
IPC: F02M65/00
Filed: 1960-08-02
Abstract: 981,601. Cleaning nozzle bodies. LESLIE HARTRIDGE Ltd. Aug. 2, 1961 [Aug. 2, 1960], No. 26723/60. Heading F2N. Apparatus for cleaning the nozzle bodies of the injectors of compression-ignition internalcombustion engines comprises a cleaning nozzle 8 adapted to receive a nozzle body x, means for forcing cleaning liquid through the nozzle body by way of the cleaning nozzle, means for supplying compressed air to the cleaning nozzle so that the air passes through the nozzle body, a valve 19 adapted to control the flow of compressed air to the cleaning nozzle and a pump 47 adapted, when operated, to force liquid through the cleaning nozzle, and means for bringing about operation of the pump and for opening and closing the valve. As shown, the nozzle 8 is secured to a tee-union 6 held in the base of a bowl 2 supported by a dished base 1, and having an integral bar 18. Laterally-spaced fingers 66 urged towards each other by a spring 67 and arranged one on either side of a vertical dolly 12 are pivoted on a bracket carried by a transverse shaft 15 rotated by a handle 17 and mounting lobes 31, 55 for operation respectively of the valve 19 and of the pump. An air pipe 35 is joined to a connector 34 at the base of the valve, and the two-ways 37, 41 of the connector lead respectively to a fume aspirator tube 38 having a discharge nozzle 39 in an exhaust pipe 40 and to a pipe 42 joined to the one side 43 of the union 6; the pump 47 is joined by a pipe 61 to the other side 62 of the union and by a pipe 59 to a filter 60. In cleaning a nozzle body, the domed, transparent cover 71 is raised and the body is located on the nozzle 8. The cover is lowered and the lever 17 moved downwardly so that the fingers 66 are splayed by the upper cone of the dolly 12 and are then allowed to approach each other to contact and lie on opposite sides of the nozzle body near to a shoulder y of the body or a shoulder on an adaptor previously applied to the body; when the fingers are in position further movement of the bracket 64 is prevented by a stop 77 but the shaft continues to turn by virtue of a spring connection 69 between the bracket and the shaft. The lobe 31 opens the valve 19 so that compressed air passes to the nozzle body and then closes, after which the lobe 55 causes the pump piston 48 to be depressed and force liquid through the nozzle body. The lever is allowed to return to a vertical position so that the lobe 31 re-opens the valve 19 to cause a second stream of air to pass to the nozzle body and to allow the fingers 66 to release the body. Liquid trapped in the bowl drains through a screen 5a into the base 1. A nozzle body may be cleaned in the reverse direction by using a cleaning nozzle in the form of a cup.
