Title: Television clamping arrangement
Inventor: JONES JAMES DOUGLAS
IPC: H04N5/18
Filed: 1971-02-12
Abstract: 1276484 Television PYE Ltd 12 Feb 1971 4547/71 Heading H4F In a D.C. clamping arrangement for the synchronizing signals of a composite television signal, to reduce the false clamping due to signal "drop-out" produced for example due to magnetic recording or interference picked up by a local receiver, in which the composite signal is amplified 9, clamped 10 to black level during back porch periods and amplified 11, the synchronizing pulse separator 13 which actuates the clamping circuit 10 is inhibited from producing an output during the video signal line periods by the output of an astable multivibrator relaxation oscillator 14. In the absence of a synchronizing signal input to oscillator 14 from separator 13, the oscillator produces a squarewave output at its natural frequency i.e. it oscillates between a first free running state whose period is longer than a line blanking period and a second state whose period is equal to a video signal line period. When in its second state the oscillator output, via gate 17, inhibits the operation of separator 13. When a composite video signal is applied to the arrangement at input A, a synchronizing pulse wlll after a few line periods reach separator 13 when the oscillator is in its first state i.e. separator 13 is operational. This is because the duration of each cycle of oscillator 14 is greater than one complete line period. From then on the oscillator 14 is triggered into its second state by each clamping pulse derived from separator 13. Since it is desired to clamp the signal during the vertical sync periods of a composite (interlaced) television signal, a frame key pulse is produced by a second sync pulse separator 15 and an integrator and limiter unit 16 which inhibits gate 17 during the vertical sync periods.

Filed: 1940-03-12
Abstract: 536,854. Time switches. ALKIN R. L., and CRANHAM D. R. March 12, 1940, No. 4594. [Class 38 (v)] In a switching device adapted to close a circuit for a pre-determined time, setting for the desired time is first effected by rotation of a shaft j, provided with knob and dial, through a predetermined angle, and a lever l is then rotated clockwise to turn a shaft k thereby moving a mercury switch mounted on the shaft into the " on" position and releasing the clockwork mechanism. In the form shown the shaft k carries a lever m n which carries an arm o normally engaging the fly p of the clockwork but moved away from it when the shaft k is rotated . The rotation also moves a pin m<1> so that it engages and is locked in a recess q' on a lever q, q<1> biassed by a spring s. After the pre-determined time has elapsed, an arm j' on the shaft j engages the arm q<1> and releases the lever m, n which returns to its original position operating the mercury switch " off." In a modification, the shaft j of the clockwork is held against rotation by a pawl lever engaging a ratchet wheel on the shaft.

Abstract: 829,854. Variable - speed gear ; friction clutches. ALLIS-CHALMERS MANUFACTURING CO. Feb. 12, 1958 [Feb. 20, 1957], No. 4659/58. Class 80 (2). [Also in Group XXXIV] A two-speed planetary gear between a driving (or driven) shaft 16 and a driven (or driving) shaft 17 in a tractor or electric motor drive system &c., comprises a sun-gear 22 fast on the shaft 16 meshed by planet pinions 29 on a carrier 28 fast with the shaft 17, the planet pinions also meshing a ring-gear 23 normally locked-up with the planet carrier by a multidisc friction clutch 68 biased to engage by springs 53 acting between the ring-gear and a reaction ring 47 . . . 49, leftwards movement of a pressure member 63 in a non-rotary housing 11 to engage a multi-disc friction brake 69 and station the ring gear simultaneously acting through the reaction ring 47 . . . 49 against the bias of the springs 53 to disengage the friction clutch. Accordingly an indirect ratio between the driving and driven shafts is obtained. The arrangement is such that as the brake 69 is applied, the clutch 68 is gradually disengaged, and vice versa, so that there is no transitional period during which the gear is in neutral and torque is not transmitted between the driving and driven shafts. In the form shown, the pressure member comprises a ring piston 63 moved to engage the brake 69 against the bias of springs 67 when fluid under pressure is admitted to a cylinder 65. As wear of the friction discs of the clutch 68 and the brake 69 takes place with use of the gear, the reaction ring 47 . . . 49 gradually moves rightwards, when moved to the clutch-engaged position by the bias of the springs 53, to effect automatic adjustment, so that the distance travelled by the ring piston 63 when establishing a change from direct to indirect drive &c. does not increase, with corresponding increase in time-lag during ratio shifts. A number of variable-speed gears according to the invention may be arranged in series, to obtain additional ratios, and the shaft 16 may be connected to a reverse gear (not further described).

Title: Improvements in and relating to electrical position control systems
IPC: G08C19/48
Filed: 1941-04-15
Abstract: 609,297. Electric control systems. DANNATT, C., and METROPOLITAN-VICKERS ELECTRICAL CO., Ltd. April 15, 1941, No. 4932. [Class 40 (i)] In a positional control system, means responsive to the relative displacement of a control member and a load is connected to electric means controlling the equipment for positioning the load, by two circuits each comprising in series means for producing an A.C. voltage dependent on the displacement, means for producing an independent A.C. voltage and a rectifying device. The two A.C. voltages are in aiding relationship in one circuit and opposing relationship in the other, the circuits in which these relationships occur being dependent on the direction of the displacement. The outputs of the rectifying devices produce opposed control actions in the electric responsive means. In the arrangement shown, the output 9 of a receiving selsyn is connected to the primary of a transformer having two similarly wound secondaries 14, 15 and the supply 4, 5 is connected to a transformer having oppositely wound secondaries 18, 19, the arrangement being such that 18 aids 14 and 19 opposes 15, or vice versa, depending on whether the output 9 is in phase or counterphase with the supply, that is according to the direction of the displacement. The respective .outputs of the interconnected secondaries are applied over rectifier bridges 22, 24 to the control windings 10, 11 of a reversible driving system such as a Ward-Leonard system, a metadyne system or electric motor, or a relay controlling any suitable motive equipment. By suitably proportioning the displacement and constant voltages in the secondary windings, the arrangement may be made self-limiting as regards the control action. With increase of displacement voltage up to the point at which it is counterbalanced by the constant voltage in one circuit, increase of current in one coil 10 is accompanied by decrease in the other (opposing) coil 11. Thereafter, further increase in 10 is accompanied by an increase in the opposing coil 11. Specification 609,295 is referred to.
