Title: Method and system for the transfer of latent and sensible heat between air streams
IPC: F24F3/14
Filed: 1971-07-30
Abstract: 1318829 Thermal regenerators MIDLANDROSS CORP 30 July 1971 [4 Nov 1970] 35932/71 Heading F4K Heat is exchanged between humid air streams flowing respectively through contact towers 11, 24, by a circulated heat transfer medium comprising a hygroscopic solution whereby both latent and sensible heat transfer is effected between the two air streams. Example given of suitable hygroscopic solutions are an aqueous salt solution of lithium chloride, calcium chloride, zinc chloride, lithium bromide; or organic hygroscopic solutions such as the glycols. As shown, exhaust air is withdrawn from a space or from a process into the tower 24 by a blower 25 and flows upwardly through packing 27 in contact with hygroscopic solution descending from sprays 32; the air passing througy spray eliminators 33 before reaching the exhaust duct 34. The solution collects in a sump 34 and is circulated therefrom by a pump 16 through a control orifice 17 to sprays 18 in the tower 11. From the sprays 18 the solution flows through packing 13 in contact with an upwardly flowing fresh air stream drawn through the tower by a blower 22. The air stream passes through a spray eliminator 19 before reaching the blower 22 and may receive further unspecified treatment before being passed to the space or process. The solution collects in a sump 23 whence it is circulated by a pump 29 via control orifice 31 to the spray nozzles 32. Arrangements utilizing a plurality of towers for each of the air streams are described (Figs. 2, 3), and these may have either individual sumps or a common sump.

Abstract: 813,478. Trolleys for overhead travelling hoists. HOLM D. KROHN-. Nov. 19, 1957 [Dec. 5, 1956], No. 35970/57. Class 78 (4). [Also in Group XXXII] A trolley for a cable crane or ropewav has at least one pair of supporting wheels whose axes are inclined at equal and opposite angles a, Fig. 2, to the 'horizontal and are also turned out of a plane normal to the rope through equal angles b, Fig. 4, in the same direction. This is stated to give a closer contact between the wheels and the cable and thus to prevent the wheels jumping off the track and to reduce wear. Where more than one pair of wheels is used, as in Fig. 4, wear can be further reduced by giving different angles a, b to each pair of wheels.

Abstract: 1,078,030. Arc rupturing. ENGLISH ELECTRIC CO. Ltd. Oct. 9, 1964 [Sept. 12, 1963], No. 35985/63. Heading H2B. A high - voltage A.C. circuit - interrupting arrangement comprises a superconducting switch and a series-connected circuit-breaker. In one arrangement the superconducting switch is connected in series with a normally-open circuit-breaker across a normally closed circuit-breaker. When a fault occurs, the normally-closed circuit-breaker is opened, the normally-open circuit-breaker is closed at a suitable instant before a current zero, a critical magnetic field is applied to the superconducting switch to switch it from its superconducting state to its high resistance state at the current zero, and the series-connected circuit-breaker is then opened to interrupt the residual current through the superconducting switch. In another arrangement the superconducting switch is normally in circuit and is switched to its high-resistance state when a fault occurs, the series-connected circuit-breaker being opened at the next current zero. In this arrangement the switch is shunted by a capacitor and a resistance. The superconducting switch may be that of Specification 1,078,029 and the circuitbreaker or each circuit-breaker may be that of Specification 960,402.

Abstract: 620,180. Toasting apparatus. WILSON GAS METERS, Ltd., G., DOBSON, W. A., and POOLE, D. C. E. Dec. 5,1946, No. 36018. [Class 28(i)] A slice of bread is toasted on a support 13 during vertical movement of the support between and past a pair of spaced heaters 11, under the action of gravity, its movement being slowed by a rotary air vane or by an air dashpot with an adjustable bleed valve permitting quick return of the support. The support may be hingedly secured at 17 to a slide 21 mounted in guiding slots in pillars 19 having racks engaging gears 32 on the slide driving through a pawl and ratchet wheel 29, Fig. 3, gears connected to the air vane 20. Two or more slice supports 13 may be secured on opposite sides of the slide 21. The gas supply to burners 12 may be reduced on completion of the toasting stroke by a pin on the slide 21 engaging a scroll 41 on a valve control spindle 40 and rotating the latter. Valves 43 selectively control the gas supply to heaters not in use. Alternatively, the heating may be reduced or stopped by a spring catch maintaining the support in raised position prior to descent or, (Provisional Specification), during the termination of the previous toasting stroke, the heating being only restored on release of the catch. The toast may be kept warm by using an upper position of rest and a counterweight driving it to that position.

[Also in Divisions F3 and G6] A finned tube of the type illustrated in Fig. 1 having longitudinal splitter fins 12 defining sectors A, B, C and D occupied by heat exchange fins 15 is made by a hot die-pressing process whereby the tube, fins 12 and fins 15 are formed integrally with each other. In the die-pressing apparatus shown in Figs. 7 and 8 a cylindrical tubular workpiece 30 is set up on a vertical mandrel 31 which passes through the central aperture 34 of a radially slotted guide block 35. Eight dies 45 having tapered inner portions 46 and part cylindrical end faces 47 are slidably mounted in the radial slots 44 of the guide block 35 and are connected to the movable casings 52 of eight hydraulic jacks 53. Cam plates 60 are secured to an actuating disc 62 so that on rotation of the latter the cam plates depress buttons 58 and the jacks 53 are actuated to move the casings 52 and dies 45 simultaneously inwardly. The die faces 47 are grooved with a pattern which is the converse of the required tube fin pattern so that with the apparatus illustrated the above method produces a tube having eight splitter fins and sectors. The dies are subsequently withdrawn radially and the workpiece raised vertically, the process being repeated for successive sections of the tube.
