Filed: 1960-08-13
Abstract: 991,722. Upholstery. DUNLOP RUBBER CO. Ltd. Aug. 4, 1961 [Aug. 13, 1960], No. 28103/60. Heading A4M. [Also in Division B5] Three or more superposed layers, e.g. three to eight, of flexible thermoplastic sheeting are heat-sealed together, e.g. by H.F. heating, along parallel lines, and are then divided into strips, preferably along some or all of the sealing lines, to form upholstery webbing. The sheeting may comprise plasticized polyvinyl chloride, a vinyl chloride-vinyl acetate or vinyl chloride-vinylidene chloride copolymer, polythene, isotactic polypropylene, a polyamide or a polyester such as polyethylene terephthalate, and the layers may include additional layers of fabric or other material. The sealed layers may be divided transversely in which case the spacing of the sealing lines is preferably equal to the length of the strips to be finally produced. The ends of longitudinal strips may be heat sealed or turned over and edge sealed to provide a loop for a retaining pin or the like. An example describes the folding of an 80 inch wide sheet of plasticized p.v.c. into four and the passage thereof between pairs of disclike H.F. electrodes spaced ¢ inch apart, and then between slitting knives spaced at 2 inch intervals. As shown, webbing units 51, 52, 53, made by slitting a multiply sheet, sealed along the parallel lines, into three, cross-sealing at intervals corresponding to the desired length of strip, and dividing each strip along the sealing lines into three longitudinal strips between their end seals, are secured to a seat frame 54, adjacent sub-strips being connected to each other or to the frame by clips 55.

Title: Improvements in or relating to furnace cooling systems
IPC: C21B7/10
Filed: 1929-09-17
Abstract: 339,972. Mullen, B. J. Dec. 19, 1928, [Convention date]. indicators and alarms; leakage in water jackets, detecting.-In a blast furnace or similar cooling system in which water is circulated at a pressure lower than that in the furnace, floatoperated signal means are provided for indicating abnormal conditions in the system. The apparatus shown comprises a gas tight float chamber 28 connected through valves 21, 19 with a pipe 14 which conveys exhaust water from the cooling- system to the waste main 15. The float is carried by an arm 34 fixed to a shaft 35 mounted in bearings 36, 37, and coupled at its free end to the operating member 47 of a double pole switch. Both terminals on one side of the switch are connected to a power main by a lead 50, while the terminals 51, 52 on the other side are connected respectively to a horn alarm 55, and a lump panel 56. A signal lamp 59 on the float chamber is in parallel with the corresponding lamp on the panels. To prevent escape of gas at the bearings the shaft 35 is forced into the coned seating 41 by a spring-pressed block 41<a>. Au indicator arm 46 extends through a slot 46<a> in the casing. In operation any gas which has leaked from the furnace into the cooling-system is separated from the water by the pivoted baffle 18 and collects in the float chamber. The liquid level in the chamber is thus depressed, and when it reaches a certain point the switch is operated to complete the circuits through the alarm and the lamps. A glass sight tube 23 is fitted so that the rise of bubbles can be seen, and the inlet to the float chamber is covered by a cap 26 to prevent the rising stream from disturbing the float. In starting the apparatus the liquid level is so adjusted that the switch is in the off position when the chamber 28 is put into communication with the pipe 14, and this can be effected by vertical adjustment of the overflow pipe 62<a> and by pouring liquid or shot into the channel 64, Samples of gas entrapped in the chamber can be taken through the cock 75. The apparatus may be fitted in the inlet pipe of the cooling system, and in this case the operation depends solely on the pressure of the water supply. Where the alarm device is used for a number of cooling units, e.g. bosh plates, connected in series, each unit can be tested separately by closing the valve 19, and putting the chamber 28 in communication with the unit through the valve 21, branch 22 and a temporary connection to a fitting similar to the part 17. The Specification as open to inspection under Sect. 91 (3) (a) describes the portable testing device shown in Fig. 6, (Cancelled). This comprises a glass walled chamber 80 which can be screwed on to a fitting 17<a> having a valve 19<a> and a gas separating plate. 18a adapted to be moved out of operative position when the tester is not in use. Gas samples can be taken through the branch 88 and water may be taken to waste through the connection 90. This subject-matter does not appear in the Specification as accepted.

Abstract: 887,681. Change-speed control. EATON MANUFACTURING CO. Aug. 18, 1959 [Nov. 5, 1958], No. 28262/59. Class 80 (2). [Also in Group XXXIV] To engage a brake 11, Fig. 1, on a changespeed gear countershaft 12 driven through continuously meshing gears 15, 16 from an engine 57, a knob 13 mounted on a ratio shift lever 26 or elsewhere, is depressed by an operator to connect a source of pressure fluid 74 and a pipe 75 through a valve 70 to a pipe 68 leading to a valve 66, movement of the ratio shift lever 26 to the neutral position sliding selector rods 22 ... 24 which condition the usual drift pins 28 to open the valve 66 so that pressure fluid is supplied through a pipe 65 to energize a servomotor 64 engaging the brake, the pipe 65 also leading through a pipe 76 to a one-way restricting valve 77 and a reservoir 78, the pressure in which is accordingly gradually raised until a valve 80 is opened to supply pressure-fluid to a servo device in the valve 70 actuated by the knob 13, this pressure serving to restore the valve 70 to its original position, venting the pipes 68, 65 to exhaust 72 and disengaging the brake. Thus the brake 11 is disengaged a predetermined time after it has been engaged, irrespective of the rapidity with which a ratio shift is effected, this time being not more than that required to achieve full synchronization in the gearing. The valve 70, Fig. 2, comprises the knob 73 fast with which is a servo piston 97 in a cylinder 91 connected by a pipe 81 to the valve 80, depression of the knob connecting the pipes 75, 68 to pass pressure-fluid to the valve 66, and increasing pressure in the space 91, forcing the piston 97 together with the knob 73 and valve pistons 95, 96 upwards to the position shown, where the pipe 68 is connected to the exhaust pipe 72. The drift pins 28 also actuate a switch 50 controlling an auxiliary transmission (not further described). The engine 57 is connected to the gears 15 &c. through a clutch 58 disengaged by a pedal 62 which may alternatively actuate the valve 70. The countershaft gearing is similar to that described in Specification 681,759. Instead of pressure fluid, electric means may be used. Specification 844,120 also is referred to.

Abstract: 364,019. Coin-freed liquid-dispensing apparatus. BEATTON, R. S., Yass Street, Young, New South Wales, Australia. Sept. 25, 1930, No. 28679. [Classes 27 and 106 (v).] Supply and discharge passages 14, 21 may be brought into communication with the measuring chamber 10 by passages in the rotatable valve 11. The chamber 10 may be rotated instead of the valve, and the supply and discharge passages may be in separate upper and lower members. An overflow pipe 27 determines the maximum quantity retained for delivery from the chamber 10. Instead of being delivered directly the liquid may pass from chamber 10 into an intermediate chamber. A time-release gear may be connected to the measuring chamber so that undelivered liquid will be drained back to the supply reservoir. Coin-freed mechanism may be associated with the valve stem by combining the lower end of the stem with a ratchet disc 32 engaged by a pivoted lever 33. Coin action, weight; coin-discharging mechanism. -The coin 41, inserted at slot 35, lodges between the toe 39 of the lever 33 and the push arm 40 on pressing which the disc 32 is released for rotation. When the cam 42 reaches the lever 33 the latter is depressed sufficiently for the toe 39 to disengage the lever 38, permitting the coin to drop. Testing coins.-The levers 36, 37 are so weighted and mounted that coins over or under weight are ejected at the opening 45.

Abstract: 364,542. Hydraulic couplings. VOITH, W., VOITH, H., and VOITH, H., (trading as VOITH, J. M.), Heidenheim, Brenz, Wuftemberg, Germany. Sept. 25, 1930, No 28761. Convention date, Sept. 25, 1929. [Class 69 (ii).] Control mechanism for the coupling described in Specification 353,440 comprises means for admitting liquid to the hydraulic slip coupling, and subsequently, when the driven shaft has attained a predetermined speed, to the friction coupling, the slip coupling being emptied after the engagement of the friction coupling. When the coupling is to be engaged, pressure liquid is admitted to the pipe 1, Fig. 3, and passes through valves 2, 3 to a servomotor 4 to open a valve 5, so that a vacuum in the coupling casing 22 causes liquid to be sucked through a pipe 6 and passage 8 into the coupling. When the driven member of the coupling has attained a predetermined speed, a governor 11 opens a valve 12, so that liquid passes from the pipe 1 to a servomotor 14 to open a valve 15 to permit liquid to be sucked through a pipe 16 and passage 17 to a space 19, to cause the friction coupling to be engaged. After the engagement of the latter, the valve 3 is closed, causing a spring to close the valve 5, and the slip coupling is emptied by a vacuum connection at 25 and a waste water pump connection at 26. Should the vacuum in the casing at 22 fail, the pressure in the casing acts through a servomotor 27 to operate a valve 29, so that pressure water passes through 'nozzles 36, 37 and supplies the necessary liquid to the coupling by injector action. A member 43 actuates a valve 44 so that lubricant is supplied for a limited time to the friction coupling at engagement or disengagement. In a plant comprising a turbine T, Fig. 1, motor generator MG, coupling C, and pump P, the turbine and pump valves are connected to the valves 2, 3, so that the latter are closed when the former are open.

Title: Improvements in or relating to gas turbine plants
IPC: F02C1/08
Filed: 1945-10-30
Abstract: 604,156. Gas turbines. SULZER FRERES SOC. ANON. Oct. 30, 1945, No. 28777. Convention date, May 16. [Class 110 (iii)] In a gas turbine plant of the type in which a high pressure turbine produces the useful output and a low pressure turbine drives at least one auxiliary machine and means are provided to byepass the high pressure turbine so as to control the output, a part of the working medium byepassing the high pressure turbine is led away from the plant and the remaining part is mixed with slightly heated air before passing to the low pressure turbine. The exhaust from the useful output turbine 19 may pass to an exhaust gas turbine 23 or to a heat exchanger 7 according to the setting of the valves 21, 22. The turbine 23 drives a compressor 31 which supplies make-up air to a circuit containing a compressor 1, a heatexchanger 5, a heater 9 in a combustion chamber 10, a turbine 12 driving the compressor 1 and a cooler 15. Valves 27 and 28 which are operated simultaneously with the valves 21, 22 bring the compressor 31 into or out of operation with the turbine 23. Air bled from the circuit at 6 passes through the heat exchanger 7 and acts as combustion air for the burner 17 in the combustion chamber 10 supplying gas to the turbine 19. The output from the turbine 19 is controlled by adjusting the valves 42, 43 in the inlet pipe 18 to the turbine and the byepass pipe 38 respectively. Part of the working fluid passes to a chamber 41 where it is mixed with air from the compressor 1 before passing to the turbine 23 and the remaining part passes direct to the exhaust pipe 25 through the pipe 39. A valve 45 controls the amount of air taken from the compressor 1 and a valve 44 controls the amount of working fluid passing through the pipe 39. The invention may be applied to any plant in which a turbine for driving one or more auxiliary machines is arranged in series after a useful output turbine.
