Title: Improvements relating to transducers
IPC: G01L5/16
Filed: 1962-02-15
Abstract: 999, 956. Dynamometers; anaemometers; measuring electrically. GARRETT CORPORATION. Feb. 15, 1962, [Feb. 16, 1961], No. 5860/62. Headings G1N, G1R and G1W. A transducer for measuring the two components of a couple between a first member 22 and a second member 50 about mutually perpendicular axes includes a flexure unit H comprising two pairs of beams 27 and 32 all parallel to each other and perpendicular to said axes, the lines housing each pair being parallel to one and to the other axis respectively, one pair 32 having corresponding ends connected to one member 22 and the other pair having its corresponding ends connected to the other member 50 whilst the remaining ends of one pair are connected to the remaining ends of the other pair, there being means 31, 35 responsive to the bending of the beams about the axis joining them. The beams (which are shown in development in Fig. 6) are located at opposite corners of a square, the first and second members and the connecting means being formed as a hollow cylinder 26 having our pairs of longitudinal slots 28 one pair on each side of each beam and two pairs of semicircumferential slots 30, 34 which join each slot 28 to a corresponding slot spaced just under 180 degrees away from it. The movement of the beams is damped by the controlled flexion around a shaped surface 40 of two centrally mounted cantilever springs 36, 38 whose ends protrude through the curved slots 30, 34 as shown in Fig. 2. In the embodinent described a unit V below the unit H measures vertical flexion. The unit V includes a cylinder 46 at either end of which are clamped by a bolt 61 one end of each of a group of three flexure springs 48 set at 60 degrees to each other and each having its other end passing out through a hole in the will of the cylinder 46 to be clamped by a bolt 60 to the wall of a surrounding cylinder 47. The cylinder 46 and 47 are attached respectively to the members 42 and 50 so that vertical movements of the members relative to each other flex the springs of which the movements are recorded by strain gauges 64. Ingress of moisture into the units V and H is prevented by the use of O-rings, as at 74, and by a bellows-diaphragm 76. A heater 87 and silica-gel drying agent 88 are also included. The instrument can be inactivated by turning a knurled ring 77 which inserts locking wedges at 88, 86. For electrical recording appropriate pairs of the strain-gauges are made to form arms of a Wheatstone bridge of which the output is amplified and recorded or displayed. The embodiment particularly described consists of an anaemometer for measuring the force and direction of a wind or other fluid flow. A wind-detecting member T comprising a perforated metal spheroid 10 or sphere (Fig. 7, not shown) protectively covered with a plastic layer and having inside it an imperforated foamed plastic lining 11 is bolted on to the member 22. The latter member is provided with an electric magnetic clamping device consisting of a copper disc 24 arranged between ring magnets 23. Specification 999,957 is referred to.
Patent GB-723907-A (GB)
Title: An improved machine for producing fins for finned tube core structures
IPC: B21D53/02
Filed: 1952-03-06
Abstract: 723,907. Making heat-exchangers. LAWRENCE, J. W. May 4, 1953 [March 6, 1952], No, 5888/52. Classes 83 (2) and 83 (4). Punching, shearing, flanging, drawing, beading.-A machine for producing fins for use in the construction of finned tube heat-exchanger core structures comprises a pair of co-operable rollers one roller having integrally formed teeth or punches which co-operate with complementarily shaped recesses in the other roller, the rollers being further provided with complementary formations which are interspersed with the teeth and recesses and adapted to produce air-deflecting protuberances on the metal strip. The top roller 1 has punches 4 which cooperate with complementary recesses 5 in the roller 2. Each punch has flat ends 4a and is bevelled to form a cutting edge 4b. When a thin metal strip, e.g. of copper, is fed between the rollers each punch forms a rectangular opening 6 in the strip, said opening having side flanges 7 and triangular end lips 8, Fig. 12, for receiving flat section tubes of the heat exchanger. The roller 1 has also partly spherical protuberances 9 disposed between the punches, these protuberances being complemented by cup-like hollows 10 in the roller 2. The protuberances form imperforate air-deflecting portions in the strip between the openings 6. Either or both of the rollers may be driven by an electric motor through reduction gearing. The roller 1 may consist of separate discs 11 mounted on the roller shaft 18 by means of a rubber sleeve 17 interposed between rings 17a and 17b. The roller shaft 18 is mounted in adjustable bearing blocks 19. The edge folder provided in front of the rollers comprises two adjustably-spaced pairs of folder elements 25 and 26, the elements 25 being raised above the base plate 24 of the machine to enable the strip to pass beneath it, said elements being held together by connecter plates 27. The opposed edges of the folder elements are contoured as shown in Figs. 5, 6, 7 and 8 to fold over progressively the edge portions of the strip which is supported and guided into the folder by a roll 30. A leather-faced spring-loaded brake 31 is mounted between the folder elements and is pressed into engagement with the top surface of the strip. A guillotine 38 is stationed on the side of the rollers remote from the edge folder and comprises a fixed vertical blade 39 and a movable blade 40 slidable in guides 41 and operated by arms 43 secured on a spindle 44 rotated by a camactuated spring-loaded reciprocating bar 47. The cam is associated with spur gears driven from a gear on the shaft 15 of the roller 2 and the frequency of the guillotine strokes can be varied by changing one of the gears. Alternatively the guillotine may be electrically operated by a solenoid. A series of gravity-controlled stripping fingers prevent the formed strip from adhering to the punches on the roller 1. Specification 723,908 is referred to in the Provisional Specification.

The relative positions of the cylinder and member 27 are adjusted as below until optimum patterns, as described in the Specification, are formed. The position of member 27 is adjusted by screws 31 whilst stationary, and by screws 30 whilst rotating. The position of the holder 21 containing the cylinder is adjusted by screws 25, and screen 35 is then moved by screws 39 to bring a pattern etched thereon, Fig. 4 (not shown), concentric with the reflected pattern. Fine adjustment of cylinder 11 is made by screws 37, 38. The cylinder may then be fixed into position e.g. by curing a resin previously applied to the ends of the cylinder. The reflected light from member 27 may be passed through a diverging lens 33 on to the screen 35.
