Title: Improvements in or relating to television and like transmission systems
IPC: H04N7/06
Filed: 1946-07-25
Abstract: 632,651. Television. CINEMA-TELEVISION, Ltd., and CHAPTER, C. F. July 25, 1946, No. 22213. [Class 40 (iii)] In a television system in which the transmission of the picture signals is effected by frequency modulation of a first carrier wave, at least one set of synchronizing signals is sent as periodic transmissions for short durations of an independently generated second carrier wave having a frequency lying within the modulation range of the first carrier wave. In the transmitter arrangement, Fig. 1, the signal output 30 from a camera 1, together with a black-out pulse 32 from a pulse generator 5, is fed to a mixer-limiter 3 to produce a signal 31 which has a fixed value during the flyback period and which controls a frequency-modulated transmitter 4. The pulse generator 5 also supplies frame and line pulses 33, 34 to time bases 6 for the camera 1 and to modulators 7, 8 controlling short-period transmissions from a pulse transmitter 9 radiating on a carrier frequency within the modulation range of the transmission from the transmitter 4. The transmitters 4, 9 may conjointly employ a single aerial or the transmitter 9 may be replaced by separate transmitters utilized for the different sets of synchronizing signals and transmitting on the same or different frequencies. In the receiving arrangement, Fig. 2, the signal output of a frequency modulated receiver 10 is applied via an amplifier 11 to the control grid of a cathode-ray tube 15 and is also fed via a limiter 12 so that solely the black-out pulses are passed to an amplitudemodulated receiver 13 which is thereby made inoperative except during the reception of the synchronizing signals. The receiver 13 is adapted to receive the carrier wave emanating from the transmitter 9 but to be insensitive to the frequency of the carrier wave emitted by the transmitter 4 during the black-out periods and its output is utilized to control the time bases 14. The output from the receiver 10 in response to the synchronizing pulses radiated by the transmitter 9 is withheld from the reproducer 15 by blocking pulses 42 applied to the amplifier 11 during the retrace periods. The receiver 13 may be rendered operative for intervals determined by some element in the time base arrangement 14. In a modification, the combined signal may be applied to a common radio frequency amplifier responsive to the whole modulation band and thereafter applied to separate units corresponding to the receivers 10, 13, one of these units being responsive solely to the synchronizing frequency and being rendered inoperative during the reception of the picture signals. One set only of the synchronizing signals may be sent on the second carrier and the other set of pulses may be transmitted as amplitude or frequency modulation of the first carrier. In a colour system impulses to control the change-over from one colour to another may be sent in a manner similar to that employed for the transmission of the synchronizing signals.

Abstract: 912,386. Friction clutches. TWIN DISC CLUTCH CO. June 29, 1959, No. 22285/59. Class 80 (2). A multi-plate friction clutch is engaged by toggle-levers 32, 34 pivoted on lugs 30, 36 formed respectively on a control collar 29 and on a ring 37 adjustably screwed on to a hub 13 carrying the driven clutch plates. To engage the clutch, the collar is slid to the left until the levers 32 are brought over-centre and lugs 41 on the collar abut the ring 37 so that the clutch is self-locked in engagement; during this movement a shoulder 40 on each lever 34 engages a pressure-plate 15 and moves it to its clamping position. Ring 37 is screwed along the hub to compensate for wear of the plates and is locked in position by a spring-loaded pin 38 engaging one of a number of pockets 39 formed in the pressure plate. When the collar is retracted to disengage the clutch, a nose 42 on each lever 34 shifts the pressure plate 15 in the release direction, and centrifugal force acting on the levers assists disengagement after the levers 32 have passed their vertical positions. The collar is slid axially by means of a hand lever which rocks a shaft carrying a yoke engaging the collar; the shaft also carries an arm in which a detent pin is mounted which, in the engaged and disengaged positions, engages notches in a strip secured to a stationary housing.

Title: Improvements in or relating to control heads and blow-out preventers for well bores
IPC: E21B33/06
Filed: 1947-08-15
Abstract: 627,196. Well-drilling equipment. HYDRIL CORPORATION. Aug. 15, 1947, No. 22751. Convention date, Aug. 16, 1946. [Class 85] A combined control head and blow-out preventer is characterised in that the plastic packer annulus P is confined between two series of segmental plates 63, 64, which are keyed to the annulus and abut against shoulders formed in the casing, the shoulders limiting vertical movement of the annulus. Radial inwardlydirected pressure is applied to the annulus either by the vertical movement of a piston 41 having a conical bore complimentary to the circumferential face of the packer or by vertical pressure on an outer plastic annulus, the radial pressure causing plastic flow inwards to seal off the bore of the control head. Verticallyopposite plates in each series may be rigidly coupled by a vertical rib 65 moulded within the packer or fitted in a peripheral slot in the packer so that flow of the plastic packer on the application of a radial pressure carries the two series of plates inwardly to assist in backing-up that portion of the plastic packer closing the bore. In the case when the opposite series of plates are not rigidly interconnected, each plate overlaps an adjacent one and radial movement is guided by an abutment pin on each plate, the pin moving in a slot formed in a ring secured to the casing. The back vertical rib may have transverse plates to assist in the control of the flow of the plastic packer. The piston may be so formed that both the well pressure and an external source of pressure under the control of the driller may act simultaneously on the piston.

Title: Fluid system
IPC: F15B21/02
Filed: 1970-05-12
Abstract: 1314072 Fluid operated positioning apparatus INTERNATIONAL BUSINESS MACHINES CORP 12 May 1970 [14 May 1969] 22930/70 Heading F1P An assembly of piston and cylinder units 15, Fig. 21, of differing strokes connected together for positioning a load are supplied with hydraulic fluid through respective pilot operated valves (not shown) fed from a line 47, 51, 52, Fig. 2B, the line containing a flow sensing system 23 which sends fluid signals to a logic unit 20, which unit 20 causes inter alia unlocking of the load and an increase in the throttling effect of a valve 17, Fig. 21, in the lines 141, 142 between the units 15 and the pilot operated valves. With the load locked in an adjusted position, opening of a different selection of the pilot operated valves first causes some units 15 to extend while others contract, the load remaining stationary. Because the load itself is not moved this operation (termed "exchange") is performed at high speed, the logic unit 20 automatically arranging for the flow sensing unit 23 and the valve 17 to allow a high flow rate to the units 15. Thus logic unit 20 causes pressurization of a line 38 and consequential opening of a valve 40. This allows pressure from a supply system described in Specification 1314075 .Fig. 2C, (not shown) and connected to the line 47, to flow through parallel paths 49, 42 to the line 51, 52 leading via the pilot operated valves to the lines 141, 142 (depending on the positions of the pilot operated valves) and thence through the valve 17 to the units 15. During "exchange" the throttling effect of the valve 17 is low. When "exchange" is completed fluid no longer flows through orifices 50 in spring loaded pistons 35, 36 in the respective parallel flow paths 49, 42 and the pistons 35, 36 are moved to the positions shown. Thus the previous connection of lines 24, 25 to a return 46 is momentarily closed. The logic unit 20 detects closure of the line 25 and acts to unlock the load and to de-pressurize lines 38, 94. The release of pressure in the line 94 allows a spring to force a spool 143 of the valve 17 to increase its throttling of the hydraulic fluid which then commences to flow to those units 15 required to move the load. The release of pressure from the line 38 allows the valve 40 to close so that the flow rate to the units 15 is reduced by having to flow only through the path 49. The units 15 are connected to a movement damping device, Fig. 2J, (not shown) as described in Specification 1314071 the device being arranged to be returned and held in a central position after re-positioning of the load. An air reader Fig. 2D, (not shown) as described in Specification 1314073 has a perforated tape advanced in steps to cause the pneumatic re-positioning of pilot valves controlling the said pilot operated valves which control the individual units.
