Title: Well safety valve installation
IPC: E21B34/00
Filed: 1971-11-05
Abstract: 1371216 Valves CAMCO Inc 5 Nov 1971 [1 June 1971] 51500/71 Heading F2V [Also in Division E1] In a safety valve installation, a valve 10 in a well conduit 42 is held open by a control pressure applied to a chamber 32 and is permitted to close on reduction of the control pressure. Control pressure applied at the surface to the easing annulus 46 passes through a pocket 48 to the exterior of the valve between seals 36, 38 and through apertures 34 to the chamber 32. On reduction of the control pressure, the pressure in a pressurized chamber 24 and that of a spring 28 moves a piston 26 on a tube 20 to free a spring- urged flap 16 to close the valve. Seals 60, 62, 64, 68 of the pressure chamber 24 are subjected to control pressure which is higher than the pressure in the conduit so that failure of one of these seals will not cause the flap to open. The seals of the pressure chamber are isolated from the pressure in the conduit by seals 72, 74. In a modification a line extending from the surface supplies the control pressure to the exterior of the valve between the seals 36, 38.
Patent GB-1104649-A (GB)
Title: Continuous averaging system
IPC: G06F17/18
Filed: 1966-11-18
Abstract: 1,104,649. Averaging. INTERNATIONAL BUSINESS MACHINES CORPORATION. 18 Nov., 1966 [27 Dec., 1965], No. 51660/66. Heading G4A. A stored average is updated by each of a succession of samples. The amplitude at each of a plurality of points on a waveform is sampled in turn, digitized and used to update a stored digital average of previous samplings of the same point, by subtracting the previous average from the new sample, dividing the difference by the number of samples (specified by a sweep counter) and adding the result to the previous average. The system performs a number of complete sweeps along the waveform, updating the averages for all the points used thereon, until terminated by a manual switch or at a predetermined count of the sweep counter. Alternatively, each sweep may be started manually. The digitizer may be dispensed with and analogue calculating circuitry replace the digital.

Title: Video signal encoding
IPC: H04N5/91
Filed: 1975-12-17
Abstract: 1537283 Television systems TRANS-AMERICAN VIDEO Inc 17 Dec 1975 [4 June 1975] 51684/75 Heading H4F The vertical sync. pulse train in a television video signal is altered in such a manner that a conventional television receiver fed with the signal will display the picture information correctly, whereas a conventional video recorder fed with the signal will not provide a recording which will give correct picture reproduction, so preventing satisfactory unauthorized recording. The alteration does not affect the first few pulses of the train, these unaffected pulses being sufficient to cause the conventional receiver to work correctly. They are, however, insufficient to cause the control track generating circuit in a conventional video recorder to generate the control signal which is necessary to be recorded with the video signal. The altered pulses also do not cause the control signal to be generated. In the arrangements illustrated by Figs. 1b-1d the first 1¢ pulses of the vertical sync. pulse train B of a conventional signal, Fig. 1a, are unaltered. In one embodiment, Fig. 1b, the remaining pulses of the train are eliminated. In another the remaining pulses are shifted relative to the blanking level E so that an integrator in the control track generating circuit of the recorder will not charge sufficiently that control signals will be generated. In a third arrangement equalizing pulses C following the vertical sunc. pulse train are also shifted, Fig. 1d. The originator of the television signals may make a recording that may be satisfactorily reproduced, but not satisfactorily copied, on a conventional recorder by feeding synchronizing signals to the signal source, e.g. a camera or video tape reproducer, to an encoder which alters the vertical sync. pulse train in the signals it receives from the source, and to a recorder which receives the output of the encoder. The encoder may be controlled so that the interval during which the pulses are altered and the extent to which they are altered may be adjusted.

Abstract: 1438437 Braking yarn as it is unwound from a drum; knitting machines WESCO INDUSTRIES CORP 29 Nov 1974 [22 April 1974] 51866/74 Headings D1C D1E and D1J An arrangement for 'braking yarn as it is withdrawn axially from a drum 12 comprises a coiled spring whose opposite ends have been secured to each other to form a continuous yarn retarding ring 16, the ring 16 having an inner contour that is smaller than the outer contour of the drum 12 before the ring 16 is mounted on the drum, the yarn wound on the drum being drawn off from between the spring and the drum and thence away through an axial bore in the drum. The drum 12 is fixed to a rotatable member 14 so that yarn can be wound onto the drum. By stretching the spring to cause it to embrace the drum the spring is subjected to a flattening action and this causes each coil thereof to be inclined with respect to the radius of the drum, the inclination being in the direction of relative rotation of the yarn as it is drawn off over-end from the drum. The spring 18 may be of steel and the portion of the drum 12 surrounded by the spring may be magnetized to retain the spring thereon and prevent axial displacement thereof thus dispensing with the need of a shoulder.

Title: Liquid level detection systems
IPC: G01K7/24
Filed: 1972-11-17
Abstract: 1450895 Monitoring liquid level and temperature LUCAS ELECTRICAL Ltd 15 Oct 1973 [17 Nov 1972] 53085/72 Addition to 1375372 Heading G1N A positive temperature coefficient resistor 13, Fig. I, mounted on the base of an insulating housing 6, is connected by a lead 15a to a metal cup 12, mounted on the lid 9 of a liquid container by insulators 8, 11, the impedance to earth through the cup 12 and liquid being low when the cup is immersed in the liquid and high when the liquid level falls below the cup. The unit 10 is connected to a multi-vibrator oscillator comprising transistors 25, 28, Fig. 2, with positive feedback via elements 32, 34, 35 and negative feedback via elements 32, 33. When the liquid reaches the cup 12, the impedance is low and the circuit does not oscillate: when the liquid level is below cup 12, the impedance is high, the positive feedback exceeds the negative feedback, and the circuit oscillates, causing an output transistor 39 to conduct, whereby a relay 41 is energized to operate an alarm 44. Additional feedback via diode 36 and resistor 37 causes the off periods of transistor 25 to be much longer than the on periods, whereby transistor 39 conducts for e.g. 90% of the time. The alarm is also operated when the cup 12 is immersed in the liquid if the temperature sensed by the resistor 13 is sufficiently high to raise its resistance to cause oscillation. For use with a road vehicle, the relay 41 may control a radiator fan, and the temperature sensing resistor 13 is mounted in a cylinder head.
