Abstract: 449,348. Tables. TRIUNA CO., Ltd., 2, Queen's Road, Teddington, Middlesex, and SPALDING, B., 3, Esmeralda Road, Bermondsey, London. March 13, 1935, Nos. 7856 and 17105. [Class 52 (iii)] In a table of the kind with one or more leaves which can be swung from an inner position to an outer position level with the top, there is fitted mechanism comprising a lever which moves the leaf supports inwards and outwards. Fig. 1 shows the underside of a table comprising under. frame bars 10-13 and two hinged end leaves which fold over the top of the central leaf, meeting centrally. When turned out, they are supported by two leaf supports each consisting of a cross-bar 23, 24 and two side bars 25, 27 forming a U-shaped member passing through the end bars 12, 13. These members are moved out or in by a rod 30 connected directly to the part 23, and at its inner end connected to levers 41. pivoted at 37 and connected by pin-and-slot devices to the part 24 ; as the rod 30 is moved the parts 23, 24 move oppositely and simultaneously. In a modification, the movement of the leaf to its outward position causes a spring plunger 60, Fig. 3, which may be replaced by a small link, to bear upon the projecting end of a rod 46 ; this is thus thrust inwards so that its inner end 52 moves about its pivot 49 a lever 48 which thus pushes out the support 23, 25 in readiness to support the leaf. Normally, the support is drawn inwards by a spring 56. Suitable parts of the top may be polished or unpolished, and a drawer may be fitted.

Title: Improvements in control means for internal-combustion-operated gas-generators of thefree-piston type
IPC: F02B71/00
Filed: 1943-06-01
Abstract: 580,532. Gas generators supplying turbines. MUNTZ & CO., Ltd., A., and BEALE, E. S. L. June 1, 1943, No. 8791. [Class 110 (iii)] (Also in Groups XXVII and XXIX] An internal combustion gas generator of the free piston type has a fuel control member to vary the quantity of fuel injected per cycle and a control member for varying the compression ratio in the motor cylinder, the control means being actuated so that as the demand on the generator decreases, first the fuel quantity is reduced while the compression ratio is maintained substantially at its maximum value and then the compression ratio is reduced while the fuel quantity is maintained at its minimum permissible value. A group of gas generators may each have an individual control system as above in association with a master control system for starting and stopping individual generators as the gas demand varies and for varying the output of the generators remaining in operation. In one form three gas generators G1-G3, Fig. 4, deliver to collectors 18 connected to a common manifold 130 supplying a turbine 131. On the inward strokes the compressors deliver to a casing 13 communicating with scavenge ports. A bye-pass valve 118 closed by a spring-piston 119 connects the collector 18 to casing 13. The manner of initiating a starting operation and the mode of operation of the plant are described in detail in the Specification. The master control lever 195, Fig. 4, actuates the main control levers of the three generators and is operated either by hand or, as shown, by a governor 187 of turbine 131. The outlet valves 117 from the collectors are under the control of a servo motor differentially controlled by the collector pressure, through line 194 and by the manifold pressure, through line 195, the device serving to keep valve 117 closed when these pressures are equal. The control oil pressure in line 200 is determined by a regulator comprising a valve 199 connected to a constantpressure oil source ROP, the valve being controlled by a differential lever 201 influenced both by the control oil pressure and through bellows 197 by the delivery pressure. If the delivery pressure falls, the control oil pressure is increased causing the individual control levers to be moved so as to increase the fuel supply. The master control lever 196 alters the setting of bellows 197. A variable datum device 198 is provided to assist the bellows 197 to maintain constant delivery pressure when a gas generator is started or stopped. Specifications 579,733 and 579,734, [both in Group XXVII], are referred to.

Abstract: 1423517 Testing tyres DUNLOP Ltd 14 Feb 1973 [26 Feb 1972] 8965/72 Heading B7C A method for simulating a burst in a pneumatic tyre, comprises preforming a hole in the tyre sidewall, plugging the hole with a hollow rubber bung closed at one end only, the closed end being disposed towards the exterior of the tyre, retaining the rubber bung in the hole, inflating the pneumatic tyre, and causing removal of the bung from the hole to simulate a tyre burst. An apparatus for carrying out the method may include a bung which is substantially circular in cross-section and which is tapered towards its closed end. The bung may be retained in the tyre sidewall by a heatrupturable member which, in use, is electrically heated to permit release of the bung. The bung 24 of Fig. 3, is retained in the tyre sidewall 25 by a strap 31 passing through a groove in the closed end of the bung. The strap 31 is attached to the tyre sidewall by bolts 26, 27 having large washers 28, 29. The strap 31 carries a ring 33 which is held by a pin (not shown), in a slot in the head of the bolt 27. The pin holding the strap 31 is attached by a lanyard 8, Fig. 2, to the mechanism of Fig. 2. In operation the pin is jerked out freeing one end of the strap 31 to allow the bung to be blown out of the tyre. The mechanism of Fig. 2 comprises a body 1 having a circular flanged base 2 for bolting over a wheel hub. A plunger 5 is movably located in a bore 3 of the body 1. The plunger is held in the position shown by the engagement of a pin 15 of a piston 14 with a notched portion 9 of the plunger. The piston 14 is urged towards the plunger by a spring 23. The pin 15 is disengaged by the pull of a Bowden cable 18. The plunger 5 then moves under the action of a spring 10 to give a strong jerk on the lanyard 8 and so cause the release of the bung from the tyre sidewall. A spring 11 absorbs the momentum of the plunger 5. A bearing 19 allows rotation of the piston 14 relative to the Bowden cable 18. In the alternative form of Fig. 4 (not shown) the bung (34) is retained in the tyre sidewall by a clip (37) which, in use, is deformed or broken by a pull on the lanyard (8). The bung (38) of Fig. 5 (not shown) has an integral collar (40) which engages the interior of the tyre sidewall (39); the bung (38) is released by a pull on the lanyard (8).
