Title: Drawing instrument for circles of large and small radius
Inventor: MCCANNON DOMINIC VIGNE
IPC: B43L9/00
Filed: 1991-11-28
Abstract: A drawing instrument has a planar base (10) and a planar pivoting member (12) rotatably mounted towards one end of the base. Both the base (10) and the pivoting member (12) are provided with apertures (22a, 22b; 28a, 28b) which can receive a drawing implement. By pressing on the pivoting member (16) and inserting the drawing implement in the base apertures (28a, 28b) the base can be pivoted about the pivoting member by moving the drawing implement, enabling arcs of predetermined, relatively large, radii to be drawn. By pressing on the base (10) and inserting the drawing implement in the apertures (22a, 22b) in the pivoting member (12), the pivoting member can be rotated to produce arcs of predetermined, relatively small, radii. Slots (20, 26) in the member (12) and base (10) enable the drawing of lines inclined to one another. <IMAGE>

IPC: H05B3/34
Filed: 1993-06-28
Abstract: A heating cable for an electric blanket or under-carpet heater has an inner heating resistance wire 1 of bare wire wound on a core 10. An inner sensing wire 4 is wound in tandem with wire 1 and is formed from a resistance wire of high temperature coefficient of resistance insulated with an enamelled coating, and may be used for temperature control by way of an optical link IC and triac T. The inner wires 1, 4, are encased in an inner sheath 11 of thermoplastic electrical insulation having a relatively low melting point. On the inner sheath 11 are wound a bare outer heating resistance wire 2, and, in tandem, an outer sensing wire 5. Cable overheat protection is achieved by the melting of the inner sheath 11 which gives rise to electrical contact between the heating wires 1 and 2. The rise in current blows a fuse F1 to prevent further current flow. Sensing wires 4, 5 may be omitted, and a further heating wire may be wound on the sheath 11, allowing different power outputs. <IMAGE>

Title: Image motion estimation using a composite digital input
Inventor: SAHAKIAN JEAN-CHRISTOPHE
IPC: H04N7/32
Filed: 1993-09-22
Abstract: For obtaining motion information by using a convention motion estimator, a composite signal obtained from both the luminance signal and the chrominance signal is applied to this motion estimator. Based on the signals (Cb, Cr) of the two chrominance components (U, V), the contour of the colored elements of the image is extracted by means of Sobel filters (9, 10), i.e. high-pass two dimensional filters generating colour contours, and the output signals of these filter are added to the Iuminance signal (2) in an adder (14), the resultant signal (3) being applied to the motion estimator. The method ensures the detection of motion even when luminance is constant across an image without the need for separate luminance and chrominance motion detectors. <IMAGE>

Title: Hydraulic oil well pump drive system
Inventor: STANLEY LLOYD
IPC: F04B53/00
Filed: 1993-03-01
Abstract: A hydraulic oil well pump drive system (100) for driving an oil well sucker rod (not shown) includes a master piston (158) positioned within a master cylinder (156) for axial displacement between first and second ends of the master cylinder (156). The master piston (158) has a piston drive rod (164) which extends through one end of the master cylinder (156). The drive rod (164) is connected to a crankpin (147) of an eccentric crank (144). The eccentric crank (144) is driven at a constant rotational speed to reciprocate the master piston (158) within the master cylinder (156) at a sinusoidal rate. A center seal assembly (168) divides the master cylinder (156) into a working chamber (170) and a pressure chamber (172) in opposite ends of the master cylinder (156). Each respective chamber defines a fluid volume which varies with the displacement of the master piston (158). The master piston (158) displacement creates a bi-directional flow of working fluid from the working chamber (170). A wellhead hydraulic assembly (111) is operably connected to the oil well sucker rod and is in fluid communication with the master cylinder working chamber (170) to receive the working fluid flow. The wellhead hydraulic assembly (111) is responsive to the working fluid flow to reciprocate an oil well sucker rod at a rate which relates to the rate of master piston (158) displacement. A gas accumulator (176) is in fluid communication with the master cylinder pressure chamber (172) to bias the master piston (158) toward the master cylinder working end, providing an upward biasing force at the wellhead hydraulic assembly (111). <IMAGE>
Patent GB-942772-A (GB)
Abstract: 942,772. Gyromagnetic compass systems. SPERRY RAND CORPORATION. Feb. 23,1962 [March 14, 1961], No. 7167/62. Heading G1N. In a gyromagnetic compass system wherein the gyroscope is slaved to a magnetic compass, an auxiliary servo loop is energized when the system is started up to bring the gyroscope and magnetic compass quickly into agreement. As shown, the heading of the gyroscope'1 is repeated via a synchro link by a shaft 13 carrying the compass card 14 and the rotor of a synchro 15 whose stator is energized by a flux valve compass 11. Any difference between the compass reading and the gyro-heading produces an error signal from synchro 15 which is amplified at 16 to energize motor 10 processing the gyro 1. At starting, a thermal delay switch 38 energizes relays 40, 41 after a predetermined delay to feed the error signal from amplifier 16 through polarized relay 44 to a motor 45 coupled to the rotor windings 48 of a differential synchro 46 located between the gyro 1 and the flux valve 11, whereby the error signal is quickly eliminated. Relay 41 automatically drops after a predetermined delay, thereby cutting out the auxiliary servo loop. Specification 823, 873 is referred to.

Title: Increasing amplifier efficiency using variable bias

Abstract: A transmitter (107) includes amplifying circuitry (203) and control circuitry (215, 217, 219) for biasing the amplifying circuitry (203) so that it operates closer to saturation with increased efficiency. The gate voltage signal (213), which provides a gate bias, is coupled to the amplifying circuitry (203) and is dynamically varied by the processor circuitry (219) in response to the value of the amplifier control voltage (211) coupled to the amplifying circuitry (203). The amplifier control voltage (211), which has a value for maintaining the output power of the amplifying circuitry (203) at a constant, is produced by the integrating circuitry (217) in response to a comparison of the detected power output signal (216) produced by the detecting circuitry (215) and the power output control signal (218) produced by the processor circuitry (219). Efficiency is realized by dynamically varying the gate voltage signal (213) to its largest magnitude so that the amplifying circuitry (203) may operate as close to saturation as possible while still maintaining a constant output power. <IMAGE>
