Title: Reversible cycle refrigeration apparatus
IPC: F25B13/00
Filed: 1964-10-05
Abstract: 1,045,093. Refrigerating; heat pumps. BORG-WARNER CORPORATION. Oct. 5, 1964 [Oct. 30, 1963], No. 40519/64. Heading F4H. In a reversible cycle refrigeration system having an indoor heat exchanger 10, an outdoor heat exchanger 12 and a compressor 14, a first reversing valve 16 is provided for selectively directing hot gaseous refrigerant to one of the heat exchangers 10, 12 and a second reversing valve 18, actuated in response to actuation of the first valve 16, is arranged to reverse the flow of refrigerant between heat exchangers 10, 12 while maintaining the same direction of flow through the expansion valve 22. A solenoid pilot valve 19 is provided to move the valve member 27 of valve 16 by connecting one of the ports 34, 35 in the ends of the valve housing 26 to the compressor suction line 56. In the position shown, hot gas from the compressor discharge line 23 is passed to exchanger 10 via a bore 30 in valve member 27 and line 45, part of the gas in line 45 being passed through a line 71 to move the valve member 37 of valve 18 to the position shown. Refrigerant leaving exchanger 10 thus passes through line 46, bore 40 in member 37, line 48, a filter-drier unit 20, an expansion valve 22, line 50, bore 39 and line 52 to exchanger 12 whence it returns to the compressor via line 54, bore 29 in member 27, and line 56. When pilot valve 19 is energized to move valve member 27 to the right (Fig. 2, not shown) hot gaseous refrigerant is supplied through line 54 to exchanger 12 and through line 70 to move valve member 37 to the right. Refrigerant leaving exchanger 12 through line 52 is then supplied through bore 38 in valve member 37 to the line 48 so that the direction of flow through filter-drier 20, and expansion valve 22 is the same as in the previous mode of operation. The sensing bulb 58 of expansion valve 22 is located on the suction line 56.

Abstract: 1300749 Centrifugal filter for gases HOCCOM DEVELOPMENTS Ltd 31 March 1970 [10 June 1969 14 Aug 1969] 29330/69 and 40597/69 Heading BIT A centrifugal filter for removing solid or liquid particles from gas comprises a drum 12 rotated by motor 20 in a cylindrical casing 2, gas passing from inlet 8a outwards through the drum to outlet 8b, coalesced liquid accumulating in a removable sump or being drained off by pipe 24, and drum 12 has a lining 15 of foamed polyurethane, acting as a filter-coalescer, and internal axial projections to induce rotation of incoming gas. As shown the projections comprise four circumferentially spaced vanes 14, and lining 15 is in four sections therebetween. Alternatively, axial ribs could be formed on or attached to a cylindrical lining 15, or drum 12 could have axial corrugations to which the lining conforms at least when the drum is rotating. The projections are of such size as to ensure maximum gas flow through the drum but not sufficient to cause inward flow through end gap 16. End wall 5 of the casing has spaced outlet holes (5a) leading to an annular outlet duct bridged by a filter element 18, of foamed polyurethane folded round metal mesh 18a, and a metal mesh screen 3. An annular baffle 5b and an axial baffle (25) (Fig. 2 not shown) direct coalesced liquid to outlet 24 and prevent its reaching the gas outlet. Fig. 1 shows the drum horizontally oriented, but Fig. 4 shows how the easing is modified for vertical or inclined mounting. The space between drum and casing is unequally divided by annular wall 2a, the gas flow 26 carrying coalesced liquid drops up the inside of the wall and over lip 2c after which liquid drains down space 21a shielded from gas flow.

Title: Wall linings for boiler furnaces
IPC: F22B37/20
Filed: 1962-10-26
Abstract: 973,056. Boiler furnace walls. SULZER FRERES S.A. Oct. 26, 1962 [Dec. 1, 1961], No. 40633/62. Heading F4B. A lining for a boiler furnace wall comprises hollow elements which carry a heat-absorbing medium, an expansion joint bridging a gap between two adjacent elements, and a tube in the gap spaced from adjacent elements by di nces each sufficient to accommod ate maximum expansion of the adjacent element, the elements being formed by at least one meander-shaped tube band. Fig. 3 illustrates a tubulous wall lining comprising similar meandershaped tube bands 34, 35, 36 and 37, the bands 35 and 36 having a common inlet header 38 and outlet header 40. The tube bands are arranged so that gaps on one tube band align with gaps on the adjacent tube bands, thus allowing one expansion joint tube to be used for two gaps as shown, for example, by the tube 47 in the gaps 44 and 44<SP>1</SP>. The tube 47 is contained in a total of four gaps, bent at 47<SP>1</SP> for resilience, connected to the headers 38 and 40 and fixed at points 56 and 57. Other expansion joint tubes are similarly fitted. The joint detail is illustrated at Fig. 2 where fins 28 are welded to the joint tube 11 and fins 27 and guide members 29 to the lower and upper tubes of the upper and lower tube band runs respectively, the finned tubes and alternate tubes of the tube band runs being supported by the members 24 whose notches 33 receive lugs 23 on the support tube 19. Guide rods 26 are welded on all tubes of the tube band runs, except the upper tube of each run. The metal skin 31 and the insulating layer 32 are thus protected from furnace radiation. At points where tubes are bent through 180 degrees the dimensions of the expansion gaps and bridging fins may be reduced to dimensions smaller than those at 90 degrees bends to relieve potentially high stresses. The tube bands may be fabricated from two corrugated sheets welded together, Fig. 5 (not shown).

Abstract: 966,226. Helicopters. J. G. WEIR. Feb. 23, 1962 [Nov. 28, 1960; Dec. 30, 1960], Nos. 40791/60 and 44793/60. Heading B7W. A helicopter rotor has a pair of contrarotating rotors in which the rotor shafts 12, 14 are driven through gearing 20 from a power unit 22. Referring to the upper rotor only, blades 32, 34 are mounted on pivots 28, 30 offset a distance d from the spanwise axes S of the blades and carried by arms 24, 26 normal to the axis of shaft 12, though in the case of a single two-bladed rotor it may be arranged to teeter. As shown in Fig. 3, when axis S and the coincident axes of shafts 24, 26 lie on a common plane AB normal to the axis of shaft 12 the blades are set at a positive angle of incidence α between 6 and 18 degrees. In second the Provisional Specification the range is given as 18 to 22.5 degrees. In the position of zero pitch of the blades shown the leading edge of a blade should preferably lie in a plane containing the hub axis and the axis of pivots 26, 28. This geometry is stated to ensure that in all conditions of flight the blades will automatically assume a position of angular displacement about the pivot axis such that the angle of attack with respect to the local relative wind, averaged along the span, is substantially constant and below the mean stalling angle of the blade aerofoil sections. A further embodiment is described in which the hub is mounted on a drive-shaft by a constantvelocity universal joint, whereby it may be tilted for pitch and roll control.
