Title: Improvements in and relating to elastic-fluid turbines
IPC: F01D17/14
Filed: 1929-04-20
Abstract: 310,332. British Thomson-Houston Co., Ltd., (Assignees of Holt, K. M., Warner, D. F., and Pollard, E. V.). April 23, 1928, [Convention date]. Regulating.-In a steam &c. turbine having a conduit through which fluid may be admitted to and extracted from an intermediate stage, and a governed interstage valve at that stage, an automatic valve is arranged to close the conduit when the interstage valve has been closed by a predetermined amount. The object is to prevent, at light loads, the intermediate supply of auxiliary fluid, and consequent racing of the turbine. The high-pressure admission valve 27 and the interstage valve 4 are positioned by servo-motors 26<b>, 12 which are controlled in known manner by interconnected devices comprising a speed governor 20<d> and' a device 22 responsive to the pressure in the conduit 3 through which auxiliary fluid is supplied, and fluid is extracted. Upon. change of speed, the valves 27, 4 are automatically adjusted in the same sense, but upon change of pressure in the conduit 3 they are adjusted in the opposite sense. The extent of closing of the valve 4 is limited by a stop 7. In the dualpurpose conduit 3 a double-beat valve 31, 32 is arranged. The head 31 is larger than the head 32, and the valve is normally held open by a servo-motor 38, the pilot valve 40 of which is. controlled by a solenoid 41, 42. A switch 46 is arranged in the solenoid circuit, so that in the event of the interstage valve 4 being closed toa predetermined extent the switch is opened by a stop 47, and the solenoid is de-energized. The valve 31, 32 then closes. and its construction is such that auxiliary steam cannot be supplied to the turbine, but steam may be extracted from the turbine.

Patent GB-528580-A (GB)
Title: Improvements in and relating to the pressure gas supply of electric switches
IPC: H01H33/56
Filed: 1939-04-26
Abstract: 528,580. Air compressors. BRITISH THOMSON-HOUSTON CO., Ltd. April 26, 1939, No. 12526. Convention date, April 26, 1938. [Class 8 (i)] [Also in Groups XXXVII and XXIX] The invention provides means for relieving pressure in pipes carrying compressed air furnished by motor driven compressors, so that after a compressor has come to rest it has only to start against atmospheric pressure. In Fig. 2 a pipe 2 supplying pressure gas from a pump to a switch has a branch 9 leading to one side of a diaphragm 15 in a chamber 6. The other side is connected by way of pipe 10 to a nozzle 12 in the supply pipe so that a flow of gas will create a difference in pressure in the two parts of the diaphragm chamber. The deflection of the diaphragm closes an escape pipe 14. When the flow of gas in pipe 2 ceases the pressures in the diaphragm chamber equalize and the gas escapes by pipe 14. In a modification the difference of pressure is created by constrictions on the branch pipe leading to the right-hand side of the diaphragm. The air escaping from the pipe 14 may ventilate the switch.

Abstract: 528,584. Oil engines. HESSELMAN MOTOR CORPORATION, Ltd. April 27, 1939, No. 12682. Convention date, April 3. [A Specification was laid open to inspection under Sect. 91 of the Acts, Dec. 12, 1939.] [Class 7 (iii)] Groups of elements in a combustion chamber each comprise a fuel jet, a sparking or other ignition device, an exhaust valve and an inlet valve and each element of one group subtends with the corresponding member of another group the same angle as each other member subtends with the corresponding member of another group. In the construction shown in Fig. 1, air admitted through passages 1, 2 rotates about the cylinder axis in the direction of the arrow 21. One passage may be of greater cross section than the other and makes a larger angle with the cylinder axis. Fuel is delivered through a central nozzle 5 towards each exhaust valve 6, 7 and the mixture is ignited by diametrically opposed sparking plugs 8, 9. In modified constructions, the fuel is delivered through nozzles at the periphery of the combustion chamber either in the direction of air rotation over each inlet valve towards an exhaust valve or against the direction of air rotation over each exhaust valve towards an inlet valve. In Fig. 2 the inlet and exhaust valves are on opposite sides of the combustion chamber and a central nozzle delivers fuel towards each valve.

Title: Improved hypodermic injector
Inventor: LOVE DOUGLAS STANLEY
IPC: A61M5/24
Filed: 1961-04-11
Abstract: 993,309. Hypodermic injectors. EXPRESS INJECTOR CO. Ltd. April 6, 1962 [April 11, 1961], No. 13038/61. Heading A5R. A hypodermic injector comprises a housing 10 surrounding the nearly uniform thin walls of an ampoule 11 to support it against any expansion when means 15 impart to its rear end first a percussive force to produce a transient high pressure which discharges medicament from the ampoule followed by a compressive force capable of introverting the ampoule as in Fig. 2 and discharging the remaining medicament from it at a reduced pressure. The front end of the ampoule may be closed by a plug 12 with a minute orifice 13 enabling the medicament to pierce the skin without use of a hypodermic needle or the plug 43 as in Fig. 7 may be of plastic formed with a thin walled nozzle 43 of large bore to cooperate with an orifice 44 formed in the cap 44 which holds the ampoule in the housing of the injector. The rear, thin wall of the ampoule may be flat, stepped annularly as in Fig. 3, or annularly bevelled (Fig. 5, not shown). The plug 43 is assembled to the ampoule shell 42 with a gap 49 which is taken up when the ampoule is screwed home in the housing by the cap 44, thereby ejecting any air bubbles present in the ampoule. The plunger 15 which applies the load to the ampoule is driven by a guide 18 which compresses springs 21 and 22 between a flange on its lower end and a flange on a guide member 17 which is held on the injector casing 16 by a screwed cap 29 which can be turned to adjust the tension of the springs. The guide 18 is mounted telescopically on the member 17 and the springs are held in compression by balls 26 located in holes 25 in the guide member 17 which are locked in a groove 18a around the inside of the member 18 by the conical end 23a of a plunger 23 on a button 28 which is movable with respect to the member 17 against a spring 24. When the button 28 is depressed the plunger head 23a frees the balls 26 from the groove 18a allowing the guide 18 to fly forward and strike the plunger 15 a blow which is followed by a steady pressure, due to the residual compression on the springs. A loading device (not shown) is provided for putting the initial compression on the springs 21 and 22. The members 17 and 18 can be locked together by rotation of a ring 34 on the member 17. Specifications 964,584 and 964,585 are referred to.

A cartridge-actuated tool for driving fasteners comprises a barrel 20 having a muzzle end adapted to be pressed against a working surface in order to cock the firing mechanism and a safety device formed by a sleeve 124 which is slidable on the barrel and arranged to be limited in its rearward movement by abutment with the housing. The sleeve 124 is mounted on the muzzle end of the barrel and normally urged by a spring 112 against a flange 116 on the muzzle. In normal use, the muzzle is pressed against a working surface as shown in order to cock the tool. If, however, the muzzle is not pressed against a working surface and the sleeve gripped by hand it is merely moved relatively to the barrel without cocking the firing mechanism.
