Title: Improvements in or relating to torque control devices
IPC: F15B11/028
Filed: 1946-05-30
Abstract: 615,748. Grinding and polishing. BALLINGER, L. J. H. May 30, 1946, No. 16477. [Class 60] [Also in Group XXII] A safety device which byepasses the liquid in the hydraulically-operated feed of a drill, cutter, grinding-wheel, &c. to a workpiece, or the feed of a workpiece relatively to the tool, in the event of excessive torque being set up between the tool and workpiece, comprises pre-loaded springs arranged in the drive to the tool which, at a predetermined torque on the tool, operate means to byepass the pressure liquid acting on the feed device. As shown, the shaft 1 carrying the tool rotatably supports on a boss 2 a pulley 7, chain sprocket, or gear-wheel driven from an electric motor. The boss 2 is keyed to the shaft 1 and is formed with ears 3 having chamfered ends engaging wedge-shaped extensions 5 formed on a disc 6. The pulley 7 has a flange 8 on which are stop pins 10 which pass through the disc 6 and form stops for the ears 3 of the boss 2, the flange also having bosses to support one end of each of two pins 13 having spherical heads engaging recesses in the ears 3. Springs 12 (not shown) on the pins 13 force the ears 3 against the stop pins 10, so that the drive to the shaft 1 from the pulley 7 is through these springs. The disc 6 is mounted on a spigot of the boss 2 and can move axially against the action of springs 11 on the pins 10. On excessive torque on the shaft 1, the springs 12 are compressed to allow angular relative movement between the ears 3 and the disc 6, the chamfered ends of the ears move over the wedges 5 of the disc to force the latter axially along the spigot mounting. The oil feed pipe 23 in the hydraulic system operating the feed of the workpiece and a relief pipe 22 are connected to a valve body 16 having a valve 18 therein, the stem 17 of which is engaged by a boss 6<SP>1</SP> on the disc 6, so that when the latter moves axially the valve is moved to allow oil to escape from the pipe 23 to the pipe 22. The valve body is screw-threaded for adjustment axially by a nut 26. The safety device could be arranged on the motor driving the shaft 1.

Adjusting reflectors from a distance.-In a vehicle or other lamp provided with a pivoted reflector arranged to occupy either of two limiting positions, a spring-device is engaged between the reflector and a fixed part of the lamp to exert a retaining action on the reflector in either of its limiting positions, and when the reflector is moved the spring-device passes through an intermediate position of maximum strain. In the form shown, a parabolic reflector a is arranged to pivot about an inclined axis by means of pivots c on a ring d detachably fixed within the lamp casing b, and a helical spring g is placed between a pair of abutments e, f secured to the ring d and reflector a. In the normal position the flange h of the reflector abuts against one side of a rubber-covered stop i on the ring d, whilst in the depressed position an adjustable screw-device j secured by a bracket k to the reflector abuts against the opposite side of the stop i. A rod s secured to the rear of the reflector is connected to the piston of a small cylinder l hinged to the ring d and connected by a flexible tube n to a hand-operated cylinder adjacent the driver's seat or to the induction pipe of the engine. Alternatively, the reflector may be operated by interconnected rubber bulbs, solenoids or other electromagnetic devices, or by flexible or other mechanical devices.

Title: Improvements for minimising the wear on the valves and cylinders of locomotives when running with the regulator closed
IPC: F01B25/00
Filed: 1922-06-21
Abstract: 192,665. Marine & Locomotive Superheaters, Ltd., (York, R. S.). June 21,1922. Fluid-actuated valves.-A valve used to supply steam to the cylinders of locomotives, when running with the regulator closed, comprises a stepped piston having four sets of piston rings. Normally, the cylinder pressure in the exit pipe 7 holds the valve closed against the atmospheric pressure on the underside of the part 2<b>. Pressure steam acting through the inlet pipe 9 acts with a balanced force against the opposed surfaces 10, 11 during this period. The production of a vacuum in the cylinders allows the atmospheric pressure to raise the valve and establish communication between the pipes 9, 7 through the ports 13, 15, 16, 17. In a modified valve shown in Fig. 3, the underside of a plain piston is subjected to atmospheric pressure which lifts the piston until a ring of holes 28 register with an annular passage 27 communicating with a supplypipe 22 fitted with a screw-operated regulating valve.
Patent GB-695513-A (GB)
Title: Manufacture of new monoalkyl-hydrazine sulphates
Filed: 1951-07-19
Abstract: The invention comprises new mono-alkyl hydrazine sulphates in which the alkyl group contains at least 4 carbon atoms and which may be produced by reacting a solution of hydrazine and a mono-alkyl hydrazine in an alcohol, containing 1-4 carbon atoms, with sulphuric acid.  The sulphates formed are separated and, if desired, the hydrazine sulphates obtained may be used for producing a fresh starting mixture.  The mixture of hydrazine and a mono-alkyl hydrazine may be obtained by reacting an alkyl halide, in which the alkyl group contains at least 4 carbon atoms, with excess hydrazine. Advantageously hydrazine sulphate dissolved in an alcohol preferably containing 1-4 carbon atoms, is converted into hydrazine by means of an alkali hydroxide; the alkali sulphate is separated and the hydrazine is heated with an alkyl halide containing at least 4 carbon atoms, so that the hydrazine: alkyl halide ratio is at least 5 : 1, preferably in alcoholic solution.  The resulting mixture is reacted with sulphuric acid, preferably of 98 per cent strength.  The hydrazine sulphate and mono-hydrazin sulphate may be easily separated because of their different solubilities.  Suitable alkyl halides are for example, n-butyl bromide, n-butyl chloride, isobutyl chloride, n-octyl chloride, n-decyl chloride, n-decyl bromide, n-dodecyl chloride, cetyl chloride, octadecyl chloride and oleyl chloride.  In the examples, hydrazine sulphate and sodium hydroxide are reacted in alcoholic solution and the sodium sulphate is filtered off; n-dodecyl chloride is added to the resulting solution of hydrazine in alcohol, the mixture is heated and then treated with concentrated sulphuric acid to give a mixture of hydrazine sulphate and n-dodecyl hydrazine sulphate; n-butyl bromide, n-butyl chloride, n-hexyl chloride, n-decyl chloride, allyl chloride, cetyl chloride or octadecyl chloride may be used instead of n-dodecyl chloride.
