Title: Improvements relating to Electrical Conductors
Inventor: BARBER ANTHONY CLIFFORD
IPC: H01L39/24
Filed: 1967-09-28
Abstract: 1170645 Super-conductors IMPERIAL METAL INDUSTRIES (KYNOCH) Ltd 6 Sept 1968 [28 Sept 1967] 44142/67 Headings H1A A5 and A4D An electrical conductor is produced by locating a ductile super-conductor member in a sheath consisting of at least one metal selected from the group Al, Ag, Cd, In, Pb, Sn, providing the sheath with an external can of a ductile metal which will support the sheath, and working the assembly to reduce its cross-sectional dimensions. Since the sheath metals specified are generally softer than the super-conductor direct drawing results in the thickness of the sheath decreasing faster than that of the super-conductor member and the use of an external supporting can of, for example, copper or mild steel reduces this effect. The can may be removed after the conductor has been drawn to the required size or may be retained if it is of copper. The super-conductor may be Nb 44 wt. per cent Ti. An initial direct extrusion of the superconductor and sheath may be performed by heating a super-conductor bar, inserting it into a cold sheath, and immediately extruding the assembly. Heating the super-conductor increases its ductility to allow direct drawing. This initial step may be omitted and the sheath may be provided with an inner layer of Cu to improve the metallurgical bond. A plurality of drawn filaments may be inserted into a can and further drawn down.

Filed: 1963-11-08
Abstract: A worsted stretch fabric has weft of plied yarn consisting of an S-twist singles and a similar 2-twist singles doubled with a twist about equal to the singles twist; the yarn is steamed before weaving to set the twist.  Weaving is effected with the warp reeded out so that the weft can bulk when the fabric is finished in the relaxed state.  The warp may be ordinary worsted yarn to produce a fabric having weftwise stretch, or may be the same as the weft to produce two-way stretch.  Details of preferred ranges of twist, grade of wool, and threads per inch are given.  Finishing.  The following sequence of operations is performed without tension; singeing; Birch crabbing at about 30 yds. per min. with water temperatures in successive bowls of 43 DEG , 54 DEG , 71 DEG , 82 DEG , 93 DEG , 32 DEG C.; tacking; scouring in a dolly or full width washer using a high liquid level, neutral or slightly acid, with no pressure or drag on the fabric, at about 50 DEG C. for 30 mins, followed by rinsing in cooler water for a similar time; de-tacking; dry relaxing with 10% overfeed at a lower temperature (110 DEG C.) and a slower speed (20-25 yds. per min.) than normal; visual examination; top steaming on an open steam table at 10-15 yds. per min. with saturated steam at 100 DEG C.; tacking; dyeing; de-tacking; dry-relaxing as above; examination; shearing; top steaming again; Yorkshire crabbing (optional); cold water shrinking at 32 DEG C. in a bath containing a wetting agent; loop drying in warm air (about 120 DEG C.) for 5 mins. at 20 yds. per min; repetition of the cold water shrinkage and loop drying; semi-decating with steam at 100 DEG C. for 5 mins. and suction for 5 mins., the fabric being wound on a perforated cylinder together with a hard leader blanket (or full decating in an autoclave with steam at 10 lbs. per sq. in for 3 mins., followed by 8 mins. cooling).

Abstract: 1308810 Fuel injection pumps ROBERT BOSCH GmbH 18 Sept 1970 [19 Sept 1969(2)] 44609/70 Heading F1A In a fuel injection pump in which the delivery is controlled by a spill valve 14 actuated by liquid delivered by an auxiliary piston 18 movable with the injection piston 2, the valve 14 controls connection between a spill passage 16a and two low-pressure passages 16b, 33. The passage 33 is connected to the spill passage 16a before the passage 16b, but the passage 33 is only open during part of the stroke of the pistons 2, 18. The closing of the passage 33 occurs when a groove 34 in the piston 2 no longer connects the two parts of the passage 33. In operation at full load, opening of the passage 33 only occurs after it has been previously closed by the piston 2, so that no spillage occurs through the passage 33. When "hydraulic stop" of the valve 14 occurs, as determined by the adjusted size of a variable orifice 31, the passage 33 is connected to the spill passage 16a and some fuel spills before the passage 33 is closed by the piston 2. Delivery then re-commences until the passage 16b is opened. Fuel spilling through the passage 33 may be controlled by a fixed throttle formed in the valve 14, Figs.4 and 5 (not shown) or by a needle valve in the passage 33, Fig.3 (not shown).

Title: Digitizing tablets

Filed: 1976-11-11
Abstract: 1499498 Measuring linear displacements INTERNATIONAL BUSINESS MACHINES CORP 11 Nov 1976 [22 Dec 1975] 47024/76 Addition to 1492730 Heading G1N [Also in Division G4] In digitizing tablet apparatus, the position of a sensor (e.g. manual "pen") capacitively coupled to wires is determined with the aid of the sensor outputs produced in response to three successive activation patterns applied to the wires, two of these patterns involving a 0-1 transition at the sensor position and displaced from it by the pitch between wires respectively. As disclosed, an X-Y grid of wires is provided. The procedure for each dimension in turn is as follows. The coarse position (i.e. which two adjacent wires the sensor lies between) is determined by applying an alternating voltage signal, increasing in amplitude along the array of wires, the sensor output being divided by the sensor output from applying the same alternating voltage signal to all the wires to compensate for variations in sensor height. The fine position is then obtained by applying the alternating voltage signal to the right-hand one of the two adjacent wires and at least some wires to the right of it, and not to the left-hand one of the two adjacent wires and at least some wires to the left of it, i.e. providing a 0-1 transition at the sensor position if 0 and 1 mean a non-energized and energized wire respectively, and the sensor output is taken. Another sensor output is taken with a 0-1 transition one position to the right of the sensor position, and a third sensor output is taken with a 1-0 transition at the sensor position (using the complement of the first activation pattern used in determining the fine position). The fine position is calculated from the three sensor outputs, the procedure compensating for variations in sensor height. The alternating voltage signal is a pulse train from a generator. The sensor output is converted to D.C., digitized and fed to a processor. Drivers for applying the alternating signal to the wires can be controlled from a control register loaded from the processor, the register having two bit positions to select between X and Y, 12 bit positions to control (in the selected dimension) 12 drivers respectively directly and 12 drivers respectively via EXCL-OR gates controlled to invert or not by another bit position of the register.

Patent GB-473815-A (GB)
Abstract: 473,815. Valves. HAHN, O. W. Dec. 30, 1936, No. 35705. [Class 135] [Also in Groups XI and XIII] In a thermostatically controlled gas burner 2, gas is supplied through a box 6 containing any desired automatic control for adjusting the flame to suit heating requirements. The main gas valve 14 controls ports 12, 13, and ports 15, 16 are controlled by valve 17 . Port 12 admits gas to the main supply pipe 5<1>, and port 13 admits gas through conduit 24 to a pilot burner 26. Port 15 also supplies the pilot burner when valve 17 is open, and port 16 supplies a ring burner 30 which ignites the pilot burner. A slot 31 is formed in the supply pipe to the burner 30 so that the gas can be ignited at the point 31<1> and the flame will travel along to the burner 30. The valves 14, 17 may be actuated selectively by a cam 33 operated by a hand lever 22. The lever 22 is bifurcated at its lower end to form a pair of lugs 34, 35 spaced apart a sufficient distance to pass the upper end 36<1> of a latch 36 which is mounted so that it may be set in the path of either lug. The lower end of the latch 36 is notched at 38 to rest on a fulcrum 39 and the upper end is pressed outward by a spring 41 against the retaining action of a rod 42 attached to one end of a n-shaped heat-responsive element 47 arranged over the pilot flame. A push-button 50 is provided whereby the latch 36 may be pressed in independently of the rod 42. The inward movement of latch 36 under the pull of rod 42 takes place about the fulcrum 38, but the outward movement takes place about the fulcrum 39<1>, so that the upper end of the latch then moves a shorter distance. The member 47 is of steel containing 18 per cent chromium and 10 per cent nickel with holes 51 around its inner curve. This portion is subject to heat from the pilot flame, the holes serving to reduce conductivity to the outer periphery, so that the free end of the element moves in the plane of the element. An alternative form, Fig. 6, may be used. If the pilot flame is extinguished, rod 42 is retracted, and latch 36 is withdrawn from the path of the outer lug 35 of lever 22, which allows valve 14 to close main burner port 12 and pilot port 13. Continued retraction of rod 42 pulls latch 36 into the path of lug 44 so that lever 22 cannot be moved to open valve 14 but can be moved to open valve 17, when the slot 31 in the pipe 29 can be lighted, the flame travelling along to the burner 30 and thence to the pilot 26. Heat from the latter expands the member 47 which releases latch 36 so that the main valve can be opened. Valve 17 then closes ports 15 to the pilot and 16 to the burner 30.
