Abstract: 1,028,841. Gasholders. GENERAL AMERICAN TRANSPORTATION CORPORATION. Feb. 6, 1963 [Feb. 16, 1962], No. 4803/63. Heading F4X. [Also in Division B5] In a dry-seal, pressure-type gasholder comprising a piston vertically movable in a container and a ring-like flexible diaphragm sealed adjacent its inner and outer perimeters to the piston and the container respectively, the diaphragm is formed of a foamed elastomeric material provided on its inner gas-contacting surface with a material which is inert and impervious to the gas, the diaphragm being both circumferentially stretchable and compressible whereby the piston can move upwardly or downwardly without the formation of folds or creases in the diaphragm as it feeds from the piston to the container wall and vice versa. In one form, Fig. 2 (not shown), the gasholder comprises a cylindrical wall 12 having a floor 13 and a conical roof 14 and containing a piston 15 with an upstanding cylindrical fender 16 spaced inwardly from the wall to leave an annular space 17 therebetween. An annular diaphragm 20 is arranged in an upwardly directed loop 23 in the space 17, being sealed to the shell by a bar 31 and to the bottom of the fender. As the piston moves from its lowest position to its top position the material of the diaphragm feeds from the fender to the container wall through the loop 23. In a modification, Fig. 3 (not shown), two pistons are provided one nested within the other. The outer and inner circumferences of the diaphragm in its free state are from 0À6 to 2% less and greater than the circumferences of the container and piston respectively, the diaphragm being respectively stretched and compressed at its outer and inner peripheries on installation to fit the container wall and piston. The diaphragm material is such that wrinkles and creases are not formed therein either during installation or operation, the outer layer being formed of a sheet of elastomeric organic material of cellular structure such as foamed synthetic rubber or a synthetic organic resin, e.g. foamed polyester or polyurethane resin, with closed or open cells whilst the inner layer consists of a polysulphide or nitrile rubber, polychloroprene, a copolymer of butadiene and acrylonitrile modified with polyvinyl chloride resin, polyester resin, polyester of ethylene glycol and terephthalic acid or polyurethane resin. The layers are bonded together by a layer of adhesive comprising rubber, nitrile rubber or polyester or polyurethane resin which retains its elasticity after setting. The inner layer may be reinforced with cords of nylon &c. In a modification the diaphragm is of three-ply construction, the inner layer being of a polyester of ethylene glycol and terephthalic acid, the intermediate layer of textile fabric reinforced nitrile rubber and the outer layer of foamed polyurethane resin.

Filed: 1944-03-16
Abstract: 578,387. Refrigerator cars. BURGESS, A. F. (Wincharger Corporation). March 16, 1944, No. 4915. [Class 29] [Also in. Groups X and XXXVI] In a refrigerator car having ice bunkers 17 at the ends a fan 48 draws air from the lower end of each bunker upwardly through ducts 73 at each end of the car and through ducts 38 extending along the upper part of the car and delivers it into the interior of the car by a discharge opening 52 near the centrally located doors 24. The vertical ducts 73 communicate with both the interior of the car and the lower parts of the ice bunkers 17 the tops of which communicate with the interior of the car by openings 75. Warm air rising from the goods passes through the openings 75 and downwardly through the ice in the bunkers to mix with the air from the floor of the car passing upwardly at 74 through the ducts 73. An electric generator 36 driven by one of the wheels 30 supplies the fan 48 and also energises heating coils 42 within the duct 38 under the control of a thermostat 72 to avoid unduly low temperatures. To maintain the air circulation when the car is stationary a plug 67 (see Group XXXVI) connected to the station mains is inserted in a socket 55 and supplies the fan 48 and heating elements 42 through contact pins 69. Simultaneously a rod 68 on the plug disconnects contacts 60, 61 within the socket to break the circuit of the generator 36. The air flow from the fan is deflected by a cone 54.

IPC: H03K17/81
Filed: 1961-02-13
Abstract: 936,632. Circuits employing bi-stable magnetic elements. INTERNATIONAL COMPUTERS & TABULATORS Ltd. Jan. 23, 1962 [Feb. 13, 1961], No. 5239/61. Class 40 (9). Load circuits each consisting of an output winding 4 of a switch core 1 having a rectangular hysteresis characteristic in series with a rectifier 5 and a column or row winding 7, 12 of a magnetic storage matrix 8, are connected in parallel to a constant current source 9, the switch cores being set by signals in windings 2 to a pattern of magnetic states defining a particular load, and reset by a pulse in a common winding 3 to the same state whereby the induced output winding voltage causes the major part of the constant current to pass through the selected load. Normally the constant current is evenly distributed in the various loads and functions as a bias for the matrix store. Two embodiments are described; in one embodiment one switch core only is set and reset by pulses in windings 2 and 3 respectively, the induced voltage on resetting acting in the same direction as the rectifiers 5 so that the major part of the constant current passes momentarily through the associated load circuit. In the other embodiment all the switch cores except one are set, and the resetting operation induces voltages in the output windings which act in the opposite direction to that of rectifiers 5. Thus the major part of the constant current passes momentarily through the load circuit associated with the single unset core. The circuit of the constant current source induces a limiting resistor 10 and smoothing inductor 11, and the load circuits may be shunted by a rectifier 14 to reduce the quiescent current through each load.

Abstract: 573,978. Wireless signalling. ROBIN - SON, J. April 4, 1940, Nos. 6125/40 and 5553/41. [Class 40 (v)] To obviate the interference in a receiver due to the strong field produced by a local transmitter, as in a relaying system, an auxiliary transmitter operating on the same frequency as that producing the strong field is provided to produce an interference pattern and the receiver collector is so located as to reduce the interference. In addition, discrimination may be obtained by using a directional or loop aerial or by taking advantage of differences in polarization. A vertical aerial may be arranged at a trough in the interference pattern or two such aerials may be used in parallel spaced apart on opposite sides of a trough. Alternatively, the collector may comprise a loop and a vertical aerial, the signals from which are combined without phase change. Fig. 2 shows a local transmitter A and an auxiliary transmitter B with the receiver O in line with the transmitters and using a directional collector having a polar diagram p. Fig. 4 shows a relay station A for a remote transmitter T in which an auxiliary low-power transmitter B is provided and the receiver O is disposed near the transmitter B and connected thereto by a conducting line c of such a length as to provide an equivalent path distance equal to the path distance between the transmitter A and receiver O so as to operate over a range of frequencies. In a modification, Fig. 5, a directional receiver is used with the minimum towards the relaying transmitter. The receiver may supply signals to the relaying transmitter and to the auxiliary transmitter through amplifying means which may include frequencychanging and re-conversion to the original frequency. The phase and amplitude of the auxiliary transmitter may be adjusted to provide a desired interference pattern.
