Title: Improvements in electrically operated apparatus for indicating fluid pressures, liquid levels and other physical quantities
IPC: G01L9/00
Filed: 1941-07-23
Abstract: 549,468. Variable resistances. G.B. EQUIPMENTS, Ltd., and LAW, T. A. July 23, 1941. No. 9338. [Class 37] Electrically-operated apparatus for indicating fluid pressures, liquid levels, movements, &c., includes a contact member consisting of a thin metal strip continuously in contact with a resistance and connected to the moving member of the apparatus so that it is bent to vary the position of its point of contact with the resistance according to the position of the moving member. The apparatus shown is secured to the bottom of a tank in which an aperture is cut and is adapted for indicating the level of liquid in the tank. The body 14 is secured to a ring 18, which surrounds the aperture and is in turn secured by screws to another ring inside the tank. The upper surface of the body 14 is recessed to form a chamber 26, within which is a metal bellows 28. The lower wall of the bellows is secured to the body 14 by a metal bush 30, while the upper wall is free and is covered by a perforated plate 34. Motion of the bellows is transmitted through a rod 36 to the centre of a resilient flat metal strip 44, which may be of phosphor bronze, housed in an insulating casing 46. One side of the strip 44 makes contact with a resistance 54 and the other side with a metal plate 56. These are carried by two arms of an insulating support 52 which are curved as shown. As the bellows is depressed by pressure of liquid in the tank the strip 44 is bent downwards in the middle so that the points at which it makes contact with the resistance 54 and plate 56 move inwards towards the mid point of the strip. At its mid point the strip 44 carries a pin 57 which slides in a bore in the support so that the mid point is constrained to move in a straight line vertically, the ends of the strip being free to slide. The ends of the resistance 54 are connected to two terminals 58, and the plate 56 is connected to a third terminal 60. These terminals are connected to a source of current and a voltmeter, which may be calibrated in terms of liquid level. A groove 62 is formed in the casing 46 for the reception of the cable carrying the conductors, and an insulating cover 64 is secured to the casing by screws 66. Connection is made between the terminals 58, 60 and the ends of the resistance 54 and the plate 56 by means of coil springs 68 engaging metal bushes 70, embedded in the casing 46, and sockets 72 embedded in the support 52. The support 52 is carried by three screws by which it can be adjusted vertically and levelled. The interior of the bellows 28 and the chamber carrying the resistance are placed in communication with the air space at the top of the tank through a tube connected to a coupling 84. Warning of a lower limit of pressure is given by the strip 44 in its straight position engaging two contacts 86 and thereby operating a signal.

Abstract: 668,684. Ice-making. BRITISH THOMSON-HOUSTON CO., Ltd. April 17, 1950 [April 21, 1949], No. 9381/50. Class 29 A domestic freezing tray comprises a pan 6 having an outer thin flexible pan-shaped element 7 covering at least the bottom part of the pan and sealed to the pan along its upper edge to exclude moisture from between the flexible element and the pan. When the pan is lifted by the handle 10 the pan bottom is pulled slightly apart as shown at 12 from the flexible element, which peels away from the evaporator shelf 2 thus breaking the ice bond. The pan is formed of two nested aluminium elements welded together at their flanged upper edges 8, 9 and provided with dividing plates 11 as described in Specification 506,103. Three pan-shaped elements may be nested together and sealed at their edges, or the outer pan-shaped element may be shallow and sealed to the inner pan near its bottom.

As shown, a number of diverging fan outlets 15 are rotatably mounted about a hub 14 of the fan casing, and the assembly of outlets is adjusted by Bowden wires 19 from a handle 20 operated by the driver. The outlets are supplied with liquid from pipes 21 extending into them, and the pipes are fed via hose from junction pieces, each of which may be associated with a shut-off valve or metering device. Liquid is drawn from the tank through a pipe 41 and fed through a pipe 44 and a multi-way fitting 45 to a pipe 50 extending through the tank. The tank liquid is agitated by the emission of liquid from nozzles 51 in the pipe 50, and the latter also feeds further pipes leading via a shut-off valve 54 to the junction pieces. The fitting 45 includes a release valve allowing liquid to return to the tank when the pressure becomes excessive. The pump may also be used to fill the tank. The fan casing is in two parts joined by flanges 30, and forms a chamber enclosing a centrifugal fan 31. Air entry openings are provided in the part 32 which is bolted to a gear-box 33 having upper bearings for the fan shaft 34 and lower bearings for a primary shaft 35 connected by joints 36 to the shaft 37.

Abstract: For tying a compressed bale (10,50) tending to expand primarily along a major axis, a bale tie (30,60) made preferably from steel wire or alternatively from steel strap is bent to form two marcelled portions (40,70), which are characterized by sinusoidal undulations, which are oriented so as to be generally parallel to the major axis, and along which the tie can straighten to absorb tensile forces. A joint (34,64) is formed at the opposite ends of the tie. Where bent to form the marcelled portions (40,70), the tie has an ultimate strength less than the ultimate strength of an undeformed portion of the tie but more than the ultimate strength of the joint. An apparatus for forming a wire with a marcelled portion comprises upper rolls (130) and lower rolls (140), which are mounted rotatably and respectively on an upper block (108) and a lower block (110). The upper block is mounted pivotally to the lower block. <IMAGE>
