Title: Improvements in pipe connections to tanks containing gas under pressure
IPC: F16K1/30
Filed: 1956-05-08
Abstract: 837,425. Pipe connections. SOC. FINANCIERE ET INDUSTRIELLE POUR LA FABRICATION DE L'ACIDE CARBONIQUE PUR ET AUTRES PRODUITS ALIMENTAIRES PAR ABREVIATION L'ACIDE CARBONIQUE PUR. May 8, 1956 [April 23, 1956], No. 14245/56. Class 99(1). In a connection to a tank containing gas under pressure and comprising a branch 1 the free end of which may be connected to a gassupplied consumer apparatus, there is a screwthreaded stopper 15 mounted for free rotation in a lug 16 while being held thereon, the lug being pivotably mounted in loose fashion on a spindle 17 fast with the branch so that the stopper can be applied to the free end of the branch and screwed therein. A valve 6 within the branch is urged by a spring 7 on to a valve seat 5 and is opened by a member 8 which is moved by a connecting part of the apparatus. As shown, the member 8 has gas passages 9 and a frusto-conical seating 10 for the reception of a sealing means or olive 11 and is mounted on the valve 6; the member is slidable in a sleeve 3 secured within the branch 1. The latter is provided with gas passages 14 on an external screw-thread 2. The lug carries annular packings 24, 25, has a loop 19 which surrounds the spindle 17, and is formed with a central aperture provided with projecting edges which enable the stopper 15 to be screwed into the lug. In a modification, the sleeve 3 is dispensed with and the part 8 slides directly upon the wall of the branch 1, the latter having the valve seat formed thereon.

Title: Improvements in or relating to the supply of compressed combustible gases to internal combustion engines
IPC: F02M21/00

Abstract: 375,942. Pressure regulators. SOC. DU GAZ DE PARIS, 6, Rue Condorcet, Paris, May 14, 1931, No. 14316. Convention date, Feb. 20. [Class 135.] In a pressure reducing device for use in apparatus for the supply of compressed combustible gases to internal-combustion engines, comprising a spring-loaded diaphragm of resilient material operating toggle mechanism which in turn causes a valve to be pushed from its seat, means are provided for adjusting the extent to which the toggle mechanism can transmit the diaphragm displacement to a thrust pin for opening the valve. In the pressure reducer A shown in Fig. 1, a diaphragm 1 operates by means of a spring 2 adjustable by means of a threaded sleeve 3, a rod 21 pivoted to toggle links 4, pivoted to connecting members 5, 5<1> also pivoted upon a baseplate 6. The stroke of the members 5, 5<1> is limited by means of an adjusting screw 7 and a stop 8, which prevents the toggle links 4 from reaching the dead-point. The member 5<1> abuts against a thrust rod 9 capable of holding a fibre wad 10 in a holder 14 from its seat against the action of a spring 13 removable by. unscrewing a stopper 12 to which it is attached. In Fig. 2, compressed gas from cylinders 15 passes through a coil 16 insulated from an exhaust pipe 24 and the surrounding air to permit a small transfer of heat, to the inlet 11 of the pressure reducer A and thence through the outlet pipe 17 to the branch 171 of a 'Y' pipe, the other branch 18 of which communicates at the end 25 with the atmosphere. Valves 19, 20 situated in the branches 171, 18 respectively are connected by adjustable links 21 operated by the accelerator pedal. The tail 22 of the 'Y' pipe where air and gas mix and a carburetter 27 are connected to a three-way cock 26 communicating by a pipe 28 with the engine so that either gaseous or liquid fuel may be used.

Class 20(ii) In advancing mine roof supporting beams at the coal face, a beam supporting arm 1, Fig. 2, is connected to a roof beam 5 already in position so that a forward part of the arm 1 having a lateral bracket 2 extends cantilever fashion beneath and spaced from the part of the roof to be supported, the new roof beam 6 is placed with one end on the bracket 2 and is then slid forward supported on the bracket 2 and secured in roof supporting position to the beam 5. The arm 1 may be attached by bolts to the beam 5 or as shown by means of claws 3, Fig. 4, welded to the arm 1 and engaging the lower flanges of the I-beam 5. After the beams 5, 6 have been connected end to end, a screw adjustment 9 at the rear end of. the arm 1 is screwed against the beam 5 to force the rear end of the arm 1 down and with the claws 3 acting as a fulcrum, the bracket 2 moves upwards and presses the beam 6 against the roof. Instead of a screw adjustment, a wedge may be driven into the clearance between the beam 5 and the arm 1. The arm 1 is cranked laterally at 7, Fig. 1 (not shown) so that the bracket 2 is in line with the beam 5 and to permit the subsequent erection of a prop under the centre of the beam 6 whilst still supported by the arm 1.

A slow-speed chain wheel 22 drives the rear axle through one chain 24, while a second loose chain wheel can be manipulated by the clutch 27 to impart a high speed to the rear axle through the chain 29. A forked lever 30, which swings in a vertical plane to operate the clutch, is manipulated through a flexible cable enclosed in a casing. The worm wheel in some cases may be mounted on the hub of the road wheel. The storage batteries for supplying the motor, are carried by platforms 10 supported by spring-mounted rods 9 running through tubes 8 depending from the main frame. The frame comprises two horizontal tubes spaced by front and rear members 2, 4 respectively.

[Also in Group XXXV] In a remote angular position control system a transmitting machine 1 is supplied with directcurrent from source 3 and has a commutated winding on its armature from which polyphase current is obtained through rotatable brushgear 5, a motor 2, the rotor of which is supplied with polyphase current from the armature of the transmitter, is mechanically coupled to the brush-gear, and the rotors of remote receivers are also energized from the armature of the transmitter, their stator windings having directcurrent excitation. Speed control of the remote receivers is effected by means of voltages applied to the stator 13 of the motor which has at least two separate windings adapted to provide a resultant magnetic ffeld the direction of which determines the speed to be imparted to the receivers. The stator 13 may have two windings in quadrature, the difference of control voltages applied to the windings determining the speed of the receivers. Alternatively, the stator of the motor may have three phase windings, two of which may have variable excitation, the third phase winding being either de-energized or energized at a constant voltage. Each of the three stator windings of the motor may have a constant voltage applied thereto, and a central voltage, assisting the control voltage in one winding and opposing it in another, determines the speed of the receivers.

Abstract: 572,172. Photographic shutters. KODAK, Ltd. Sept. 8, 1943, No. 14737. Convention date, Sept. 23, 1942. [Class 98 (i)] A shutter includes within the casing a master member having a pivotally-mounted gear segment meshing with pinions for operating pivoted blades and also includes a pivoted cover normally spring-biassed to cover the exposure aperture and adapted to be moved therefrom by the master member after it has moved a sufficient distance during its setting or tensioning operation to ensure the aperture being covered by the blades, the return of the cover on operation of the shutter to effect an exposure to its aperture-covering. position being retarded by retarding-means to enable the blades to complete the exposure. As shown, the exposure aperture 3 in the casing 1 is normally covered by a pair of disc-shaped blades 4, each mounted on a pivot 5 carrying a pinion 6 and provided with a circular or arcuate opening 7. A master member 8 pivoted at 9 and having a setting handle 11 and a gear segment 10 meshing with the pinions 6 is operable to effect an exposure by a spring 14. A shoulder 17 is engageable by the latch member 18 of a trigger 19 turned clockwise by the spring 21. On depressing the trigger 19, the master member is released to effect the exposure, an anti-rebound device being provided as in Specification 572,173. The pivoted cover 40 has a gear segment 42 meshing with a pinion 43 carried by a fly-wheel 44 mounted on a stud 45, and is normally held to cover the aperture 3 by a spring 47. The setting movement of handle 11 tensions the master member spring 14, returns the friction shoe 26 of the shock absorber to its initial position, and by lug 24 swings the cover 40 to uncover the aperture 3, which remains covered by the blades 4. On depressing trigger 19, the blades 4 move relatively slowly, but rapidly accelerate, and since the cover 40 is retarded by the fly-wheel, the aperture 3 is not covered until the exposure is made. A flash-lamp synchronizing mechanism is provided as described in Specification 572,174.
