Abstract: 869,221. Impregnated bearing surfaces. RUSSELL MANUFACTURING CO. June 30, 1959, No. 22492/59. Class 140. [Also in Groups IX and XXV] A bearing member shaped to fit and line a ball and socket joint comprises a multiple ply fabric woven in tubular form, the ply at one face of the fabric forming a bearing surface and having warp yarns composed of polytetrafluoroethylene, the other face of the fabric being composed of warp and weft yarns, one or both of which is or are resin bondable. As shown, Fig. 1 shows a transverse section through a tubular bearing illustrating the weave, and Fig. 2 is a section on the line 2-2 in Fig. 1. The bearing shown in Fig. 1 is woven in tubular form in two plies. The inner ply has warp yarns 10 of polytetrafluoroethylene and weft yarns 11 of cotton, nylon or rayon. The outer ply has warp yarns 12 of cotton or synthetic material and weft yarns 13 which latter may be woven as crossovers 14 binding the two plies together. The tubular fabric thus has yarns of polytetrafluoroethylene which are exposed on the inner surface and are mechanically bound into a woven fabric of cotton or other yarn which can be bonded by an impregnant to a metal surface. The tubular fabric is impregnated with a suitable resin such as a urea formaldehyde condensation product and is then formed under heat and pressure into a hemispherical shape 20 (Fig. 3). Fig. 5 shows part of a steering knuckle of an automobile, wherein a bearing member 20 (as shown in Fig. 3, is located between an inner spherical member 22 and outer spherical surfaces 23. Member 22 carries a pin 25 to be connected to an external part; member 28 pressed by spring 27 secures the parts in place.

Abstract: 1358512 Web tensioning MINNESOTA MINING & MFG CO 12 May 1972 [13 May 1971] 22505/72 Heading B8R The tension in a web 19 being unwound, e.g. by web driving rollers 36, (37), Fig. 1 (not shown), from a roll held on an arbour 12 is maintained substantially constant as the roll diameter decreases by a braking torque member 16 which applies a constant braking torque to the arbour to counterbalance the decreasing frictional force applied thereto by an arbour support and brake 14. The arbour 12 is keyed to the roll core 18 and is supported at either end in semicircular grooves in support blocks 22, 25 of the arbour support and brake 14, the grooves being lined with friction material 26. The braking torque member 16 comprises leaf springs 28, 31 which urge friction pads against the periphery of the arbour. As the roll diameter decreases, the web withdrawal force due to the weight of the roll on the support and brake 14 decreases whilst that due to the resisting torque measured at the roll periphery increases.

FLAKICE CORPORATION, 900, Market Street, Wilming- ton, Delaware, U.S.A.-(Assignees of Field, C. ; 213, 90th Street, Brooklyn, New York, U.S. ,) Aug. 12, 1932, No. 22625. Convention date, Aug 14, 1931. [Class 29.] Apparatus for freezing liquids and particularly water comprises a flexible endless travelling freezing surface, e.g. an internally cooled rotary cylinder, partially immersed in the water, and means for flexing the surface as it passes out of the water to detach the ice therefrom in a continuous strip. The cylinder 33, Figs. 3 and 5, is formed of sheet-metal plates secured to rings 34 of reinforced rubber fabric and rotatably supported upon a hollow shaft 21 in a tank 4 the water level in which is maintained constant. The curvature of that part of the cylinder immersed in the water is maintained by rollers 70, while the part above the water is flexed by a smaller roller 72 to detach the ice film B which is directed on to a shoot 100 by a pivotally-mounted stripping plate 75. The cylinder is rotated through toothed-gearing from a shaft 38 driven through a reduction gear 45 and a flexible clutch 46, Fig. 4, from an electric motor 47. The cylinder is cooled by brine supplied through a duct 48 containing a filter 49 to a pipe 51 extending through the hollow shaft 21 and having at spaced intervals along its length radial pipes 52, 53, 54 connected to longitudinal pipes having nozzles 60 through which the brine is directed on to the interior of the cylinder. The used brine passes through ports 61 in the shaft 21 to an outlet port 62 connected to a duct 63 having an outlet pipe 64 and communicating with an horizontal duct 65 forming a brine reservoir. The inlet and outlet ducts 48, 63 are connected by valvedpipes 120, 121 which prevent the pressure of the brine rising unduly and syphoning of the brine from the duct 63 to the duct 48. Air and brine discharge pipes 80, 84 respectively are provided in the hollow shaft 21. The underside of the ice peeled from the cylinder may be sprayed with water supplied through pipes 98 depending from a main 95 connected to the water supply pipe for the tank 4. Specification 405,990 is referred to.

Title: Improvements in or relating to the detection or measurement of combustible ingredients in gaseous mixtures
IPC: G01N27/16
Filed: 1931-08-11
Abstract: In a device for measuring the proportion of combustible ingredients in gaseous mixtures by comparison of the electrical resistances of two heated wires, of which one serves as a standard, the heated wires form two arms Rx, Rn of a Kelvin bridge, as shown in Fig. 1.  The remaining arms R1 .. R4 are resistances of the order of 100-400 ohms, and the arm Ro has a very low resistance.  The test and comparison wires Rx, Rn are of low resistance and made of catalytic material such as a member of the platinum group, e.g. palladium, and are as far as possible identical to compensate for temperature changes.  To compensate for slight differences in their resistances, potentiometers with movable arms G1, G2 are provided, the galvanometer G being connected between these arms, and a switch 11 is arranged between the arm G2 and the mid-point of arm Ro to enable the network to be balanced.  A suitable source of E.M.F. is connected to terminals T1, T2, and the wires Rx, Rn are heated to above 300 DEG C.  A suitable arrangement of apparatus is shown in Fig. 2, wherein the <PICT:0369137/III/1> <PICT:0369137/III/2> measuring cell 22 is mounted on a bracket 21 in a casing 20, the comparison cell (not shown) being mounted directly behind it. Each cell 24 is provided with a suitable liner 24a.  The measuring cell 22 is provided with inlet and outlet pipes 25, 26 for the gas to be tested, and the comparison cell has several small openings to allow air to circulate. The catalytic wires are welded to conductors 30, 31 passing through insulating discs 32 which, together with strips 34 extending between them, form a carrier whereby the wires are readily withdrawn from the cells.  This unit is held in position by caps 35 and washers 36, contact being made by members 38, 39 formed with openings for the conductors 30, 31.  In the lower part of the casing are mounted the resistances R1 .. R4 and the potentiometers 45, 46, the arms of which are adjusted by screws 61, 62.  The arm Ro is mounted above them, and the switch 11 is arranged to contact with a stud 60 connected to the arm G2 (not shown) of the potentiometer 46.  To prevent incorrect adjustment, the switch 11 is arranged to cover the adjusting screws 61, 62 respectively in its open and closed positions.  The galvanometer and source of E.M.F. are connected to terminals 51.
