Title: Fabric seal for floating roof tank
IPC: B65D88/48
Filed: 1957-10-10
Abstract: 844,469. Tanks. CHICAGO BRIDGE & IRON CO. Oct. 10, 1957 [Feb. 13, 1957], No. 31679/57. Class 69 (1). A floating roof storage tank comprises a flexible, fabric pocket seal 113 located in the annular space between the floating roof 110 and the tank shell 111, a fluid in the pocket 113 and in direct contact therewith to maintain the sides of the pocket in direct contact sealing relationship to the roof and shell, and means for supporting the pocket from the floating roof 110, said means having an annular flexible support acting on the lower side of the pocket, said support being movable laterally in relation to said floating roof and attached to the floating roof. As shown in Figs. 2 and 3 the lower seal supporting member 129 is supported by means of a plurality of vertical bars 140, attached by means of a sleeve 141 to corresponding horizontal support arms 142 which are suspended from the lower portion of the floating roof 110 by inclined parallel hanger bars 143A, 143B. A bumper 148 is attached to each of the support bars 140. The bumpers bear against the interior surface 111 of the tank shell when the roof 110 is floating off-centre or at points of inward shell distortion. The lower portions of the tank are generally circular but sometimes the upper portions of the tank become distorted into an elliptical shape. The lower seal supporting member 129 is normally a circular ring. As the roof floats upwards with the filling of the tank the tank shell 111 will approach the bumpers 148 at the small diameter of the ellipse until contact is made. The continued upward movement of the roof will cause the tank shell to distort the member 129 inwardly at the minor diameter of the shell and outwardly at the major diameter. The hinge bars 143A, 143B are initially inclined at a small angle to the vertical so as to pre-tension the member 129. This pre-tensioning tends to carry the member 129 outwardly at the major diameter. In a modification shown in Fig. 5 the annular support which holds up the bottom portion of the fabric pocket is suspended from the upper annular support by wires 175. A bumper 176 is provided. A parallelogram support assembly supports the upper portions of the fabric seal.

Title: Improvements in electric protective devices for the discharge of high potentials
IPC: H01T19/02
Filed: 1926-12-16
Abstract: 263,170. British Thomson-Houston Co., Ltd., (Assignees of Peek, F. W.). Dec. 19, 1925, [Convention date]. Protective arrangements.-A device for dissipating excessive voltages comprises conductors connected in or to the line and arranged so that under normal working conditions substantially no dissipation of energy takes place, but between which a potential difference, causing, for example, a corona discharge, is set up by transient voltages on the line. The device may be arranged so that dielectric or resistance losses may occur under transient voltage conditions. In one form two or more parallel conductors in a mutual field of influence are inserted in the line, Fig. 2, or connected to it, Fig. 11, each having different electrical characteristics, e.g. impedance, so that though normally at about the same voltage they will assume different voltages on the passage of a surge and wave discharges will take place between them. One of the conductors may be the transmission conductor itself and another a helix coiled about it and connected in parallel with the enclosed portion of the conductor, Fig. 7. Barbs may be placed on the inner conductor. In another form a serrated conductor 21, Fig. 8, is connected to the line and a plate 22 connected to the line through a resistance. A contiguous earthed plate 24 may be included and also a condenser in the earth connection. A device of this kind may be oil-immersed, for example in a transformer tank. Solid dielectrics may be interposed between the conducting elements. Conductors connected to the line by resistances of different values may be arranged parallel with the line, all being enclosed in a solid dielectric. A modification of this is shown in Fig. 14 in which a tube of dielectric material 37 is arranged around the embedded conductors with an outer earthed conducting tube 38. In addition to -corona discharge between the conductors under surge conditions energy is here dissipated by losses in the resistances, in the dielectrics and by corona discharges. Fig. 16 shows a modification with barbed central conductors 39, conductor 40 surrounding it connected to the line by a resistance and tubes 41, 42 of dielectric and conducting material respectively surrounding the latter. A further modification, Fig. 15, comprises a surrounding conducting shield 43 connected at intervals to the line by resistances, the energy of the surge being dissipated in the resistances in passing to the shield from which further dissipation may take place.

Filed: 1935-11-19
Abstract: 466,026. Electric signalling systems. FITZPATRICK, H. J. (Maatschappij Van Berkel's Patent N.V.) Nov. 19, 1935, No. 31996. [Class 40 (i)] A registering or recording device especially for weighing-apparatus comprises a member adapted to be alternatively operatively associated with a load-influenced element of the weighing mechanism and with registering or recording means, the member being displaced together with the element when a load is placed on the apparatus and thereafter being disassociated from the element and engaged with the registering or recording means and returned to a datum position therewith so that the registering or recording means is operated in accordance with the displacement of the load-influenced element, that is, in accordance with the weight. In operation when a load is placed on the apparatus the auxiliary pointer 4, secured to the indicator spindle 3 rotates until the load is balanced, and at the same time, by means of projections 5, 6, rotates an arm 2 to the same extent. The operator closes a switch 18 which is then retained by a holding magnet 19 and causes an electromagnet 17 to rock the arm 2 about a pivot 7 thereby disengaging the projections 5, 6 and' pressing a projection 8 into engagement with teeth on a disc 9. The circuit at the same time energizes an electromagnet 21 causing a lever 22 to couple a clutch 14 to a motor 15 and to close the motor circuit through contacts 34, 35. The motor drives a printing counter 16 and also the disc 9. The disc 9 carries with it the arm 2 until the arm reaches its zero position and opens a switch 20 stopping the motor and disengaging the clutch 14. The weight may be printed on a card. The printing counter 16 may be replaced or supplemented by an electric device, Fig. 2, for operating a separate registering or recording machine (not shown). The device is driven by the motor 15 and comprises three rotatable cylinders 29, 30, 31 geared together in the manner of a revolution counter and each being provided on its surface with ten electric contacts 32 co-operating with ten contact arms 33 (one only shown with each cylinder) connected to the registering or recording machine.
