Title: Improvements in or relating to turbine control gear for ships
IPC: F01K15/04
Filed: 1954-11-02
Abstract: 762,155. Turbines. SIEMENS-SCHUCKERTWERKE AKT.-GES. Nov. 2, 1954 [Nov. 2, 1953], No. 31731/54. Class 110 (3). [Also in Group XXIX] Turbine control gear for ships wherein ahead and astern valves are operated by servomotors supplied with fluid-pressure medium, the pressure of which is controlled by regulating means structurally combined with a manoeuvring device has a reversing valve disposed between the regulating means and the valves. The turbine control gear shown consists of a quick-acting valve 1, an ahead throttle valve 2 and an astern throttle valve 3. The quick-acting valve 1 is closed by a spring and is opened by oil pressure in the space 8 which pressure may be released by the action of safety governors 6 and 7 on the high and low-pressure turbines. Pressure oil pipes 9 and 10 leading to servomotors operating the valves 2 and 3 are fed from a reversing valve 11 to which is connected a control pipe 12. The pressure in the pipe 12 is controlled by a manoeuvring hand wheel 14 acting through a regulating valve 13. A control surface 15 on a sleeve 16 varies the size of the throttling aperture of the valve 13. A valve 17 operated by a push-button 18 is provided to release the pressure in the pipe 19 and so cause the quickacting valve 1 to close. The valves 2 and 3 are operated by servomotors 24, 25 having pilot pistons 22, 23 and follow-up linkage 27. In a modification the hand wheel 14 is arranged to move a screw-threaded sleeve provided with two control surfaces to actuate the valve 13. One of these surfaces is for ahead operation and one for astern. In this arrangement the sleeve is arranged to actuate also the reversing valve. A dead surface is arranged between the control surfaces and the reversing valve is operated when the follower is on the dead surface. The quick-acting valve 1 may also be connected to the manoeuvring valve so that it can only be opened when the follower is on the dead surface. The regulating valve 13 may also be loaded by a fluid pressure by a turbine-driven pump 47 so that on an increase of speed the control pressure in the pipe 12 is lowered and the regulating valve of the turbine closed. This prevents premature operation of the safety governor.

Title: Improvements in or relating to methods of hardening alloys
IPC: C22F1/00
Filed: 1946-10-28
Abstract: Alloys comprising silver, copper and/or nickel as the main constituent and comprising an oxide-forming constituent are heated in an oxygen-containing atmosphere to harden them.  The oxide-forming constituent is one the heat of formation of whose oxide exceeds that of the main constituent by more than 45 kilogram calories per gram atom of oxygen and preferably by more than 85 kilogram calories per gram atom of oxygen, the quantity of this constituent being low enough to permit diffusion of oxygen in the alloy.  The alloy is so heated as to produce absorption of oxygen and to give an increase in hardness of more than 30 per cent.  The oxideforming constituent may be one or more of the elements aluminium, beryllium, magnesium, manganese and titanium. The treatment may be such as to produce on the alloy a layer of oxide of the main constituent, the alloy being then heated in a non-oxidizing or slightly oxidizing atmosphere to cause diffusion of the surface oxygen.

Title: Basic dyestuffs and their production
Inventor: BAUMANN HANS
IPC: C09B27/00
Filed: 1959-09-24
Abstract: Polyacrylonitrile and copolymers containing acrylonitrile are mass or spin dyed with basic dyestuffs obtained by treating compounds of the general formula:  <FORM:0879805/IV (a)/1> wherein the benzene ring of the benzthiazole may be substituted, R is alkyl, cycloalkyl, aralkyl or aryl and A is a benzene or naphthalene ring which may be substituted, with an oxidizing or dehydrogenating agent in the presence of an acid-binding agent.ALSO:Arylhydrazones of the formula:-  <FORM:0879805/IV (b)/1> where R is alkyl, cycloalkyl, aralkyl or aryl, A is a benzene or naphthalene radical which may be substituted and where the benz ring of the benzthiazole nucleus may be substituted are made by reacting a quaternary salt of the formula: <FORM:0879805/IV (b)/2> where Z- is an anion and B is a reactive radical such as halogen, alkoxy or alkylthiol, with the appropriate arylhydrazine in the presence of acid-binding agents.  In an example, 3 - methylbenzthiazolone - (2) - phenylhydrazone is obtained by reacting in aqueous solution 2 - methylmercapto-3-methylbenzthiazolonium methosulphate with phenyl hydrazine in the presence of sodium carbonate.ALSO:Basic dyestuffs are made by treating a compound of the general formula:- <FORM:0879805/IV(c)/1> wherein the benzene ring of the benzthiazole may be substituted, R is alkyl, cycloalkyl, aralkyl or aryl and A is a benzene or naphthalene ring which may be substituted, with an oxidizing or dehydrogenating agent in the presence of an acidbinding agent. The latter may be inorganic or organic but when they are primary or secondary amines they may react and enter the dyestuff molecule.  Thus in examples, 3-methylbenzthiazolone-(2)-phenylhydrazone is oxidized (1) with ferric chloride in the presence of aniline to give the product of the probable formula:-  <FORM:0879805/IV(c)/2> and (2) with potassium hexacyanferrate in the presence of morpholine to give a product which after treatment with hydrochloric acid has the probable formula:- <FORM:0879805/IV(c)/3> Further examples are given.  The dyestuffs are soluble in water or hydrophilic organic solvents and dye leather and textile materials or goods of mordanted cotton, silk or synthetic fibres such as those of polyamides, polyurethanes, acrylonitrile polymers, polyesters or cellulose esters, giving violet-blue to blue-green colours.

Abstract: 1495651 Spring mechanisms WESTERN ELECTRIC CO Inc 7 Aug 1975 [9 Aug 1974] 32968/75 Heading F2S [Also in Division G3] Patterns are formed on a workpiece by causing relative reciprocation between the workpiece and a pattern forming means; the reciprocating motion taking place between springs and energy being imparted in synchronism to maintain uniformity of reciprocation. As shown, Fig. 1, a pattern is stored in an apparatus 11 on magnetic tape and pattern information is used, in synchronism with movement of a carriage 18 to control a modulator 16 and a stepping motor 21 whereby a raster scan of a laser beam is used to reproduce the pattern on the underside of a workpiece 12. The raster is synchronized to the movement of the carriage by supplying coded position signals to the control circuit 15 from a photo-detector 22 responsive to a light beam, from a laser 23, through a code-plate 26 via a carriage mounted mirror 25. The carriage 18, Fig. 2, is reciprocated on an air bearing 32 between coil springs 33, 34. The reciprocation is maintained by impulses from the springs caused by energization of solenoids 38 by a signal from a photo-sensor 39 incorporating a carriage-mounted mask 44, delayed by a circuit 40. Each circuit 40 is arranged to delay the energization of a solenoid until the compression of a spring has reached a maximum.
