Title: Process for producing hydrogen from water using light energy and aqueous compositions
IPC: C01B3/04
Filed: 1980-04-04
Abstract: Hydrogen gas is used in industrial processes. It has potential as a fuel and as a chemical raw material but large quantities are needed The present processes for obtaining hydrogen from hydrocarbons and/or producer gas or by electrolysis of water are generally not economical. The present invention provides a process for producing hydrogen from water using light as the energy source, and aqueous compositions used in said process. Said aqueous compositions comprise at least one photo-excitable reagent which absorbs light to donate an electron and produce hydrogen. The compositions also contain a solvent and at least one reagent selected from the group consisting of chain reaction agents which are free radical formers, and spectral sensitizers, and preferably at least one reagent of each of these two types.

Title: Fixings for stator vanes
Inventor: CRAPPER DAVID NIGEL
IPC: F01D11/00
Filed: 1981-12-01
Abstract: Stator vanes 19, 21, 23 of a multi-stage axial flow compressor, e.g. for a gas turbine engine, are fixed in compressor casing 31 by "dovetail" shaped ends 25, 27, 29 or similar which mate with similarly profiled channels 33, 35, 37 in the casing 31. At their radially inner ends the stator vanes are fixed to shroud rings 47, 49, etc., which in turn seal against portions 15, 17 of the compressor rotor drum. In order to exert satisfactory torsional restraint on the stator vanes and also to damp vibrations, fixing of the stator vanes to the shroud rings is by means of one or more flanges such as 59, 61 projecting from the inner ends of the stator vanes into elastomer-lined channels in the shroud rings. The shroud ring channels may be defined between upstanding flanges such as 63-66 and the elastomer linings 67 are bonded to the walls of the channels and to the flanges 59, 61 on the stator vanes. <IMAGE>

Title: Integrated Optical Phase Modulator
IPC: G02F7/00
Filed: 1981-12-24
Abstract: An integrated optical phase modulator is formed by a body 10 of electro-optic material such as lithium niobate in which is formed a signal waveguide 12 and a control waveguide 11. Waveguides 11 and 12 adjoin one another over an interaction length L and the signal beam propagated along waveguide 12 from source 14 is phase shifted by the evanescent electric field established in the body 10 by an intense control beam propagated therealong from a source 13. The level of phase shift depends upon the intensity of the control beam, the interaction length L and the interwaveguide spacing. The modulator may form part of an all- optical interferometer or an all-optical analogue-to-digital converter. <IMAGE>

Title: Immersion soldering of aluminium
Inventor: WRIGHT WILLIAM E
IPC: B23K1/08
Filed: 1982-07-12
Abstract: A method for the immersion soldering of aluminium components is described. The components to be joined define a solder gap therebetween which is sufficiently narrow that molten solder may flow into the gap via capillary action. To promote the solder (52) entering this gap the solder (52) is ultrasonically excited by a transducer (54) prior to immersion of the components in the solder bath to reduce the viscosity of the solder. Upon removal of the components from the solder bath the surface tension and adhesive forces maintain the solder in the joint. Once the application of ultrasonic energy is discontinued, by removal of the components from the solder bath or by deenergization of the transducers, the viscosity of the solder increases further acting to help secure the solder in the joint. <IMAGE>

Abstract: 1,266,132. Drilling machine. A. P. L. THOMAS. 12 March, 1969 [12 Dec., 1967], No. 56308/67. Heading B3C. [Also in Division F2] A self-contained machining head comprising a threaded spindle 14 drivable by motor M and axially movable by a lead nut 11 drivable by motor F, the spindle and lead nut being rotatable in the same direction, is provided with a master switch which, in one embodiment (as shown), upon actuation, connects the motor F to a current supply, and two further switches subsequently operated in succession in response to changes in the axial position of the spindle, respectively to connect the motor M and one of the motors via manually adjustable thyristors or equivalent electronic devices to the supply, and disconnect the motor F from the supply. In a second embodiment (not shown), the hand of the threads of the lead nut and spindle are opposite to those of the first embodiment, the master switch connects motor M to the current supply, and the two further switches respectively operate to connect motor F and disconnect motor M. The motors may be mounted coaxially (Fig. 1) or side-by-side (Fig. 2). The spindle 14, which is splined to the rotor 6 of motor M is connected through a gear-box 17 to one or more guide bars 15 axially movable with the spindle, the two further switches being located adjacent one guide bar for actuation thereby. The positions of the switches are adjustable relative to the guide bar. The motor which is first disconnected from the supply may, at such time, be connected to a D.C. supply to stop it instantaneously. Means may be provided for inching each motor independently to permit correct positioning of the three switches relative to the guide bar 15. The gear-box may include one or more toolcarrying spindles 18. A clutch may be provided to cause simultaneous rotation of the spindle and lead nut at the same speed; the clutch engaging after disconnection of the one motor and before disconnection of the other. As shown in Fig. 2 the clutch comprises a part 37 secured to the lead nut and a part 36 rotatable with the spindle. Where the motors are arranged side-by-side, the motor offset from the axis of the spindle may be connected by toothed belt 32 either to the lead nut or to the spindle. When both motors are running the speeds are such that the spindle is fed axially slowly toward the work. A third switch can be provided for disconnecting the second-actuated motor from the supply.

Title: Casting aluminium or aluminium alloys on to other metal materials
Inventor: GRAHAM NEIL ANTHONY
IPC: B22D19/00
Filed: 1983-11-22
Abstract: A method of connecting aluminium or aluminium alloy to another metal material in which the other metal material (13) is connected first to a porous metal material (12). This may be by brazing or welding. This assembly is then placed in a die and the aluminium or aluminium alloy (10) is fed under gravity to the die and then solidified under pressure in a squeeze casting technique. The aluminium or aluminium alloy (10) penetrates the porous metal material (12) so that, on solidification, the aluminium or aluminium alloy (10) is firmly connected to the other material (13). This can find particular application in the manufacture of pistons for internal combustion engines where the piston body is of aluminium of aluminium alloy and a wear of heat-resistant insert is of ferous material. The insert may form a crown of the piston or an expansion control insert or a piston ring groove or an entrance to a combustion bowl or a combination of these features.

Title: Preparation of halogenated phenols and salts thereof
Inventor: GLADWIN KEITH
IPC: C07C37/02
Filed: 1984-02-17
Abstract: A halogenated phenol having at least three halogen atoms in the molecule, is obtained by halogenating a compound selected from phenol, monohalophenols and dihalophenols, and distilling the resulting reaction mixture in the presence of a base which contains a primary, secondary or tertiary nitrogen atom to give the desired halogenated phenol as distillate. The halogenated phenol produced as distillate may be reacted with an alkali metal hydroxide to give the corresponding salt. The invention enables the yield of salt of the desired halogenated phenol to be substantially increased as compared with its yield in prior art methods. The starting phenolic compounds may be selected from o-chlorophenol, p-chlorophenol, 2,4,- dichlorophenol, 2,6-dichlorophenol and phenol, and the resulting halogenated phenol may be 2,4,6- trichlorophenol. By using hydrazine as the base, a virtually colourless solution of the sodium salt of 2,4,6- trichlorophenol can be obtained.
