Title: Improvements in and relating to heat exchangers
Inventor: HAYDEN ROBERT LESLIE JAMES
IPC: F28D7/10
Filed: 1951-11-29
Abstract: 728,592. Tubular heat-exchangers. FOSTER WHEELER, Ltd. Nov. 3, 1952 [Nov. 29, 1951], No. 28040/51. Class 64 (3). Relates to heat-exchangers of the type employing, "leakproof" tubes 10 i.e. double-walled tubes (see Fig. 2), having a channel 15 formed between the tube walls 14, 16 for evacuating any fluid which might leak through either wall. In a heat-exchanger according to the invention, such tubes are provided with jackets 12 through which one of the heat-exchanging fluids is circulated. In the arrangement shown, the jacketted "leakproof" tubes are arranged in vertical rows, the tubes 10 of each row being connected together and forming a unit which may be readily removed and replaced if required. The connections comprise tubular spigots 18 extending radially from the jackets 12 and serving also to interconnect the jackets of a tube row in series. The individual tubes 10 of each row may also be connected in series, e.g. by U-bends (see Fig. 1B, not shown), or they may be parallel connected as shown in Figs. 3 and 4. In this latter arrangement, alternate tube rows are connected between headers 26a, 26b and 28a, 28b respectively, the jackets 12 of each row being series connected between headers 30a, 30b. A casing 32 may surround the tube assembly to collect any leakage fluid which may pass into the channels 15. The tubes and jackets may be of circular or rectangular cross-section. Specifications 703,081 and 728,131 are referred to. According to the Provisional Specification, the tubes or the jackets may be supported in holes in supporting plates or on horizontal bars.

Title: Improvements in the determination and indication at a distance of the presence and amount of combustible gases in atmospheric air
IPC: G01N25/46
Filed: 1930-09-20
Abstract: <PICT:0352817/III/1> The presence and amount of combustible gases in air is determined by oxidizing the gas by means of a platinum group metal catalyst precipitated on silica gel, the heat of reaction being caused to operate a differential thermometer.  The apparatus comprises two tubes 3 enclosed in tubes 4 which are situated in the opposite ends 5 of the differential thermometer 6.  One of the tubes 3 contains the contact agent.  The gas to be tested, after passing through a purifier 11, enters the tubes 3, passes through the apertures 15 to the tubes 4, and leaves the apparatus at 16.  The tubes may be heated by filaments 9.  A cock 8 is provided between the chambers 5 of the thermometer to permit of the calibration of the instrument.  The capillary tube 6 may be provided with contacts whereby the movement of the mercury operates an alarm.

Abstract: 1390543 Presser device PFAFF INDUSTRIEMASCHINEN GmbH 16 June 1972 [21 June 1971] 28212/72 Heading D1G The presser foot sole 20 pivoted to its shank 19 is provided with a latching means for holding the sole horizontally at the start of the sewing, the said means being unlatched as sewing proceeds. The means comprises a lever 27 pivoted at 26 to the shank and presenting a sloping upper end which engages a stop 36 on the presser bar bushing, when that bar is raised by lever 15 and mechanism 11, 13-18, to rotate the lever against its spring 33 to cause a notch 28, 29 in the other end of lever 27 to engage a pin 31 on the rear of the sole 20 to maintain the latter horizontal against the action of spring 24, the lower edge 28 of the notch being suitably inclined to achieve this. When work is just entered beneath the sole, as shown, the presser bar spring 9 exerts a torque maintaining the contact between pins 31 and edge 28 until the work has entered further, (Fig. 2 not shown) when the feed dog action tilts the presser foot to allow spring 33 to rotate the lever anticlockwise and complete the unlatching.

Abstract: 1,110, 619. Measuring pressure electrically. STANDARD TELEPHONES & CABLES Ltd. June 24, 1966, No.28288/66. Heading G1N. A vacuum gauge comprises a semi-conductor thermistor bead 14 (Fig. 2) around which is coiled a heating wire 17, contained within a glass tube 12 (Fig. 1) open at the bottom end for communication with a vacuum system to be tested. In operation the current through the heater is adjusted to a value which for example would reduce the bead resistance to about 10 k/ohms at 760 torr Fig. 3 (not shown) to give a linear relationship between bead resistance and heater current. The thermistor bead may be connected in a bridge circuit which is nulled by adjusting a calibrated resistor, to produce a measure of pressure Fig. 5 (not shown), or the unbalance voltage of which indicates pressure Fig. 6 (not shown). In the Fig. 6 arrangement (not shown) the bridge is connected in series with selectable range resistors to a stabilized direct voltage source.

Title: Improvements in or relating to a device for causing automatic lowering of the ring rails in spinning machines and twisting machines with fixed spindle rails and movable ring rails
IPC: D01H1/36
Filed: 1954-10-08
Abstract: 764,979. Stopping spinning &c. machines on completion of set. BORAS WAFVERI AKTIEBOLAG. Oct. 8, 1954 [Oct. 8, 1953], No. 29038/54. Class 120 (2). Lowering of ring rails on completion of set in spinning or twisting machines is initiated by operation of a valve so that air is delivered to one side of a cylinder provided with a double-acting piston that is coupled to the builder mechanism. When applied to a spinning machine in which the ring rail 1 is heavier than the counter-weights 5, Fig. 8, a switch is tripped by an adjustable lug 24 on a control rod 20 pivoted to a builder chain arm 7. The switch operated by the lug 24 causes a - lever 27 on a pneumatic valve 26 to be released, whereupon air enters the right-hand side of a cylinder 29 to actuate a piston rod 42, an arm 35 and a chain plate 11 to lower the rail 1. Movement of the piston rod 42 also actuates a circuit breaker 45 to stop the machine driving motor M before the rail 1 reaches its lowest position. It may be necessary with high speed machines to apply a braking force to the main driving shaft 15 and for this purpose a friction brake is applied to a drum mounted on the shaft by pneumatic means actuated from the valve 26. In a spinning machine having a ring rail lighter than its counterweights, a plate 64, Fig. 12, is provided with circumferential teeth that are numbered on the face of the plate which is rotated by a pawl 66 oscillated by a rod 69 that follows a cam 71 fixed on the heart cam-shaft of the builder motion. When a pin 77 fixed to the disc 64 strikes a lever 79, a valve 82 is operated to lower the spindle rail and stop the driving motor.

Abstract: 381,349. Protective cut-out arrangements. GENERAL ELECTRIC CO., Ltd., Magnet House, Kingsway, London, and WILSON, W., of General Electric Co., Witton, Birmingham. Oct. 21, 1931, No. 29245. [Class 38 (v).] In an A.C. protective system capable of discriminating between interphase and earth faults in lines or apparatus (such as the alternator shown), protective relay means responsive to a fault in one or more phases are rendered ineffective by operation of a further relay responsive only to earth faults, on the occurrence of an earth fault in one of the phases. Three relays 5, 6, 7 of the biased beam type have each an operating winding 8 and a restraining winding 9 and are adapted to close at 17 the circuit of the trip coil 18. Each of the phases 1, 2, 3 supplies the coil 8 of one relay and the coil 9 of another relay, so that, in the event of an interphase fault which would cause overheating of the windings, only that relay 5, 6, 7, which the operating coil 8 is energized and the restraining coil 9 is not energized closes its contacts 17. With a phase fault to earth however, the appropriate relay 5, 6, 7, is prevented from slipping by means of a residualcurrent relay 10 in the neutral, which relay opens the trip circuit at 15 or/and closes at 22 a signalling circuit or a circuit for tripping with biased characteristics.
