Title: Special amouring for submarine cable for great depths
IPC: H01B7/14
Filed: 1963-06-11
Abstract: 970,519. Cables. COMPAGNIE GENERALE D'ELECTRICITE. June 11, 1963 [June 14, 1962], No. 23142/63. Heading H1A. The tendency for an armoured submarine cable to untwist under its own weight is reduced by making the armouring wires hollow. Compared with a solid wire armouring having the same amount of steel, the increased external diameter leads to a reduction of the apparent weight in water and, because of the increased moment of inertia, to a greater torsional stiffness of the cable. To resist crushing of the armouring tubes by external pressure they may be filled with materials of density less than that of steel such as polythene, P.V.C. or a compressed gas. Access to the bores of the tubes for the fluid surrounding the cable may be provided.

Title: Improvements in or relating to percussion musical instruments such as drums and tympani
IPC: G10D13/02
Filed: 1944-12-21
Abstract: 592,979. Musical drums &c. DALLAS & SONS, Ltd., J. E., and PERCY, C. W Dec. 21, 1944, No. 23152. [Class 88 (ii)] In a percussion instrument such as a drum or tympano, the vellum is tensioned by an annular bearing member pressed against its inner surface by a series of levers pivotally mounted within the shell of the instrument. In Fig. 2, both the batter and snare vellums 22, 23 of a drum are provided with hoops 58, 64 respectively of U-shaped section and the levers 50, 63 are all actuated by the same cable 52 running through pulleys 60, 61 and 53, 54. The cable is tensioned by a screw device with an actuating knob 55. The cable can be replaced by an annular rod connected to the actuating knob and screw device 'by a short length of cable. The two vellums may be actuated by separate mechanisms. Alernatively, each lever 50 may be separately actuated by a knob 73 (Fig. 6) and a bell-crank lever 77 or by an eccentric 79 (Fig. 7) ratchet and pawl. The levers 50 may be arranged to pivot about axis perpendicular to 'the axis shown in Figs. 6, 7, but still parallel to the vellum and may be operated by a screw device or by an eccentric. Specification 589,617 is referred to in the Provisional Specification.

Title: Improvements in and relating to power operated propelling rams for railway or tramway systems
IPC: B61J3/08
Filed: 1925-09-18
Abstract: 262,867. Kershaw, A. G., and Westinghouse Brake & Saxby Signal Co., Ltd., Sept. 18, 1925. Fluid-pressure ram apparatus. -The movements of a ram 2 which propels tube or other ve. hicles, for example into a mine cage, are utilized to control the mechanically operated valve device 9 and the electromagnetically operated valve device 23 so that the ram makes a complete stroke in each direction upon the closure by the operator of a main controlling switch 17. A roller 4 on the. head of the ram operates forked levers 5, 5<1> at the ends of the stroke. The levers are connected by a link 6 and are moved in each direction in two steps, viz., at the beginning and at the end of each stroke of the ram. As shown diagrammatically, the lever 5 is mounted on a shaft 7 carrying a cam 8 and switches 15, 16. The cam 8 controls inlet and exhaust valves 10, 11 for the forward end of the ram cylinder. The switches 15, 16 control the circuit which operates inlet and exhaust valves 24, 25 for the rear end of the cylinder. In the position of the levers 5, 5' shown in full lines, the exhaust valve 11 is open and the switches 15, 16 are both closed. To stalt the operation, the main switch 17 is closed, establishing a circuit through switch 15 and solenoid 18. The latter closes switches 19, 20 and establishes two circuits, viz., a circuit through 18, 20, 19, and a solenoid 22, acting to open the inlet valve 24 so that the ram makes its forward stroke, and a branch circuit through 18, 20, 29, and switch 16, which keeps the other circuit closed when the main switch 17 is opened. The initial movement of the ram sets the levers 5, 5 in mid-position, the valve 11 remaining open to exhaust, and opens the switch 15, the switch 16 remaining closed. At the end of the forward stroke, the ram moves the lever 5<1> to its extreme position, and the cam 8 actuates the valves 10, 11 so as to effect the return stroke Both switches 15, 16 are now open, so as to open the switches 19, 20 to de-energize the solenoids 18, 22 and to open the valve 25 to exhaust. The initial movement of the ram on the return stroke closes the switch 16 without operating the valves 10, 11, and re-sets the levers 5, 5<1> in mid-position, so that at the end of the return stroke the lever 5, valves 10, 11, and switches 15, 16 are returned to their original position. The ram may be stopped and returned at any point in the forward stroke by opening an emergency switch 21 which is connected with valves 31, 32. The switch 21 is in series with the switch 16 and acts as described above to de-energize both solenoids. The valve 31 admits pressure fluid behind a piston 36 so as to actuate the valves 10, 11 and effect the return stroke of the ram. The valve 32 is open during the normal operations in order to permit of free movement of the piston 36 by the cam 8.

Abstract: 1444656 Steam irons SCM CORP 24 May 1974 [25 May 1973] 23428/74 Heading D1A An electrical pressing iron 10 Fig. 1 has a sole plate 11 with steam ports, a steam generating chamber communicating with said steam ports, a spray nozzle 24, a valve means with two outlets, the valve means being bi-stable for allowing only one of the outlets to be open at a time one outlet communicating via a tube 23 with said spray nozzle and the other outlet communicating via a tube 22 with said steam generating chamber, (for hi-speed steam) a reservoir, a pump with an inlet communicating with said valve, and pump actuation means viz a button 20 for operating said pump and for selecting said one of said valve's stable states. The pump and valve mechanisms are in a single housing 19. Up and down movement of the button 20 actuates a pump piston 34 Fig. 2 which is sealed by an O-ring 35 against a pump housing 30. The valve operated by a head 38 worked by the pump button comprises a valve member or rocker 70 which can close either valve seat 41, 42 according to the setting of the button 20. Non-return valves are provided in the pipes to and from the pump. The first of these is in the spray nozzle which includes a cap valve 53 of elastomeric material permitting water to flow out of the nozzle. A second valve 26 is mounted on the end of the tube 22 leading into the steam generator chamber. This comprises bores 60, 62 of differing diameter, separated by a slit diaphragm 61. A third valve 25 includes a spiral wire 88 Fig. 2 surrounding the valve housing 80 to prevent debris entering the valve. Alternatively standard filters and non return valves can be used throughout. The iron provides for dry ironing or constant steam, selected by a switch 15, and atomized spray or hi-speed steam ironing, selected by the button 20.

[Class 65 (i)] [See also Group XXVIII] A pneumatic engine, for operating vehicle doors and the like, comprises two cylinders 1, 2, of different diameters and each formed with an integral outer end wall, an openended gear housing 16, jointed to the open ends of the cylinders, and pistons 3, 4 in the cylinders connected by a rack bar 29 engaging a gear sector 22 fixed on a rockshaft 21 to which a door-operating lever is secured. The shaft 21 is supported by two bearings in the housing 16, one of these bearings being closed at its outer end while the other is provided with packing to exclude dirt and retain lubricant ; the bearings may be roller bearings, and are lubricated by fittings 28 at the top. The joints between the gear housing and cylinders need only be liquidtight at atmospheric pressure and are preferably without gaskets; the air in the gear housing is maintained at atmospheric pressure by a vent aperture, preferably provided with an air filter, which may be combined with a fitting for the introduction of oil for lubrication of the gears and pistons. A lug 44 on the housing limits the motion of the door-operating lever. The lever, which is described in detail, may be formed of welded steel pressings, but an alternative form, allowing limited telescopic movement, is shown in Fig. 5. In this form the roller which engages the door is carried by a spindle 36 mounted in a cross-head 56 formed with sleeves 58 slidable on rods or tubes 53 which are clamped to the rock shaft by member 42, fixed to them and having buffer pads for engaging the lug 44 on the gear housing, and member 49 and connected at their free end by a member 55 which retains the crosshead 56. Springs 57 normally hold the crosshead in the position shown, but if the door is obstructed the springs are compressed while the lever completes its motion, the door being closed by the springs when freed.
