Patent GB-833020-A (GB)
Title: Improvements relating to caliper devices
Inventor: MAYES FRED MARSTON
IPC: G01M3/00
Filed: 1957-02-28
Abstract: 833,020. Electric gauging devices. SUN OIL CO. Feb. 28, 1957, No. 6715/57. Class 40 (1). In a caliper device for tubing in a bore-hole, variations in the internal diameter of tubing through which the device is drawn modulate the frequency of an A.C. signal which is recorded on a medium whose speed varies with that of the device, and a second signal of fixed frequency is recorded as a second channel on the recording medium in order to compensate, at the reproduction stage, for variations in the carrier frequency as recorded due to alterations in the speed of recording. As shown, Fig. 1, a plurality of fingers 4 pivotally mounted in a body 2, having been rendered active for the return movement of the device by a tripping arrangement 8, are urged outwards by springs 6 to probe pits, as at P, in the internal surface of tubing T, thereby to displace a plunger 12 carrying a polepiece 22, which may be a permanent magnet or a piece of unmagnetized magnetic material, associated with a core 18 on which is wound a coil 20 which forms part of the frequency-determining circuit of an oscillator located in a casing 26, which may be sealed, and which also contains a second oscillator giving an output of constant frequency. The signals from both oscillators are recorded as separate channels on a magnetic tape within a second casing 30, which may be oil-filled, the tape being driven, through gearing and a uni-directional clutch by a roller 36 which engages the tubing wall, at a speed proportional to that of the device through the tubing. In the play-back stage, Fig. 3, each channel signal is read by a reproducing head 48 or 60 and is fed through a circuit comprising an amplifier, a limiter, and a frequency discriminator, to the grid of one of two cathode follower triodes 56, 68, between the cathodes of which is connected a recording meter 72 which registers the locations of joints and pits in the tubing. A threshold detector 74 may feed a second meter 76 for recording pits of more than a tolerated depth. Variable capacitance or resistance devices may replace the variable inductance device shown; wire, photographic, or phonographic recording may be substituted for tape recording.

Filed: 1963-02-20
Abstract: 970,221. Tuyeres. E. J. LAVINO & CO. Feb. 20, 1963, No. 6795/63. Heading F4B. A tuyere block 45, Fig. 3, is formed round a tuyere pipe 42 having reinforcing flanges 40, 41, 43, 44 which extend nearly to the faces of the block. The upper and lower flanges 40, 41 are of trapezoidal shape so that the tuyere pipe 42 is inclined relative to the top and bottom faces of the block. Notches at the ends of the tuyere pipe enable it to be supported within the mould. The flanges 40, 41 have lugs bent out to either side. In another embodiment, Fig. 1, two pairs of side flanges are attached to the pipe near the line of attachment of the upper and lower flanges. The tuyere pipe may extend beyond the end of the block, or it may terminate within the block and have a tapered or threaded end to engage a supply pipe, Fig. 7. In a modification, Fig. 10, an air supply pipe 91 with a threaded end 95 for connection to the air supply line extends within the tuyere pipe 90 proper and finishes flush with the furnace end of the tuyere pipe. In use the furnace ends of the pipes 90, 91 become fused together, and the double thickness of pipe forms a protection for the tuyere block.

[Also in Division H2] A windscreen wiper installation comprises a manually actuated switch having an "off" position and at least one "on" position in which a movable switching member 30 connects three fixed contacts 44, 45, 46 to each other, the contact 46 being connected via earth to a pole of a battery 20, the contact 44 being connected to a multivibrator comprising transistors 50, 51 and having an RC circuit 54, 55 and a resistor, or a resistor network 61 to 64, connected thereto for determining the relaxation period of the multivibrator when it is energized to operate the wiper motor 10 intermittently, and the contact 45 being connected to an end of each of the resistors 61 to 64 remote from the multivibrator. In the OFF position the contact arms 32 of the switching member are disengaged from contacts 44 and 46, and in four different ON positions an arm 32 engages selective ones of segments 65 to 68 to produce intermittent operation of the motor 10, the intervals between successive energizations being determined by the numbers of the resistors 61 to 64 introduced into the multivibrator circuit. In a fifth ON position an arm 32 engages a segment 73 to isolate the multivibrator from the resistors 61 to 64, and the motor is operated intermittently at intervals equal to the period of the discharge of capacitor 55 via a resistor 54. When a switch 24 is closed the wipers are operated continuously until the switch 24 is reopened followed by the opening of the wiper parking switch 26.

Title: Improvements in or relating to means for controlling the supply of fuel to internal combustion engines
IPC: F02D9/00
Filed: 1936-03-11
Abstract: 458,463. Regulating supply of liquid fuel. STEVENS, A. H., 5, Quality Court, Chancery Lane, London.-(Starr - Sweetland Corporation; Balfour Building, San Francisco, U.S.A.) March 11, 1936, No. 7346. [Classes 7 (iii) and 7 (vi)] Fuel supplied by a pump 73 to a pressure tank 82 passes to a primary chamber 80 and then flows past an adjustable throttle valve 47 and a metering-valve 49, to a secondary chamber 57, from which it flows to distributing-valves 54 supplying fuel injectors 7 on the various cylinders. A plunger 63 is arranged between the primary and secondary chambers and is acted on at opposite ends by the pressure in these chambers. The cams 32, 33 actuating the valves 49, 54 are so designed that the metering-valve 49 is opened and closed again just before each of the distributing-valves 54 opens. When the valve 49 is opened, the pressures on opposite ends of the plunger 63 are momentarily balanced, and the plunger is lifted by a spring 67 to accommodate the small charge of fuel admitted past the valve 49. The valve 49 then closes, after which one of the valves 54 opens. This releases the pressure underneath the plunger 63, which is then forced downwards, discharging the quantity of fuel admitted out of the chamber 57 and past the valve 54 to the corresponding injector nozzle. The opening of the throttle valve 47 is adjusted by means of a pedal 34 connected thereto by links 43, 44, and a cam 26 on the pedal lever actuates a lever 25 to adjust the timing of the cams 32, 33 by means of a sliding sleeve 18 with helical slot 29. In a modification, the plunger 63 is replaced by a diaphragm. The cylinders are provided with combustion chambers 185 with the fuel injector at 7 and a sparking-plug at 6. Fig. 5 shows a fuel injector comprising a valve seated at 141 by a spring 134 and opened by fuel pressure admitted at 137. A pintle 139 integral with the valve extends through the nozzle aperture 138.
