Patent GB-836888-A (GB)
Title: Improvements in or relating to the production of titanium and titanium chlorides
Inventor: SMOLINSKI JOSEF
IPC: C25C3/28
Filed: 1956-08-01
Abstract: Titanium di- and/or tri-chloride possibly together with titanium or an alloy thereof are produced together with lead chloride (PbCl3) or zinc chloride by bubbling titanium tetrachloride through molten lead or zinc under inert atmospheric conditions.  The metal may, if desired, be covered during or after the reaction with a layer of fused alkali and/or alkaline earth metal chlorides, whereby the evolved chlorides are immediately or subsequently dissolved to form an electrolyte from which titanium and lead or zinc may be recovered by electrolysis (see Group XXXVI).  In one example the reaction of zinc with titanium tetrachloride is conducted at 550 DEG  C. to form the trichloride and the temperature maintained thereafter until a pyrophoric mixture of titanium dichloride and zinc chloride is produced.  In another example the reaction is performed at 750 DEG C., zinc chloride vapour is evolved and the remaining products are similar to the above products but contain also metallic materials. In the examples, where a fused chloride is used, a mixture of lithium and potassium chlorides is employed.  The Provisional Specification refers to the use as reducing agents of metals whose free energy of formation is higher than that of titanium tetrachloride and lower than or equal to that of titanium lower chlorides and the reaction with molten metal is not restricted to the method of bubbling the titanium tetrachloride therethrough.ALSO:Titanium alloys may be produced by bubbling titanium tetrachloride through molten lead or zinc in an inert atmosphere. Titanium di- and/or tri-chloride may be produced at the same time (see Group III).  In an Example, a temperature of 750 DEG C. was used, as a result of which zinc chloride vapour was evolved and after cooling, the other products were leached with alcohol to leave a metallic sediment containing a brown sponge-texture alloy containing 40% titanium and a similar grey alloy consisting of 76% of titanium.  The Specification also refers to the electrolytic production of an alloy (see Group XXXVI) which contains 99.1% Ti and 0.9% Zn.

Title: Process for the manufacture of aromatic hydroxy aldehydes
IPC: C07C65/30
Filed: 1932-08-26
Abstract: Aromatic hydroxyaldehydes are manufactured by oxidizing phenols containing a propenyl group in the o- or p-position in alkaline solution by means of nitro compounds which owing to their content in sulphonic or carboxylic groups are soluble in alkaline water (except halogen-nitroaryl sulphonic or carboxylic acids containing a halogen atom in the o-position to the nitro group). In examples, iso-eugenol is oxidized to vanillin by means of a caustic soda solution of nitrobenzene-m-sulphonic acid, p-nitrobenzoic acid or 1-chloro-4-nitrobenzene-2-sulphonic acid, and 2-hydroxy-3-propenylbenzoic acid to 2-hydroxy-3-aldehydebenzoic acid by means of the first of these oxidizing agents.

Title: Circuit arrangement for blocking a binary data signal in dependance upon its transmission speed
IPC: H04L29/00
Filed: 1975-06-04
Abstract: 1500608 Data transmission; determination of data rate SIEMENS AG 4 June 1975 [12 June 1974] 24013/75 Heading H4P Incoming data D is blocked if it is above a given rate (or alternatively if it is below the rate) in dependence upon a pulse train S having a period and pulse duration varying with the data. This is effected by applying the pulses to a first timing circuit Z1 to produce pulses ml of given duration and applying the ml pulses with the data pulses S to a second timing circuit Z2 which, in response to an m1 pulse still subsisting between two data pulses, produces a data blocking pulse longer than the data slot. As shown, ml and m2 are retriggerable monostable circuits producing a zero output when triggered and the second timing circuit includes a NOR gate N. If an m 1 pulse is still zero (triggered) when the S pulse returns to zero the NOR gate triggers m2 and this has a timing period greater than the minimum desired data slot period so that it remains triggered until the reset NOR gate pulse. The data is therefore blocked by gate SP. Blocking data lower than a given rate may be effected by inverting m2.

Abstract: 802,845. Valves. WESTINGHOUSE AIR BRAKE CO. Aug. 10, 1956 [Aug. 15, 1955], No. 24549/56. Class 135. A cylindrical slide valve 16 carrying an 0- ring 20 is movable over one or more ports 22 in a bore 21 in which the valve slides, and according to the invention damage to the 0- ring by the edges of the ports is avoided by limiting the size of the ports, the width of each port 22 measured along the circumference of the bore 21 being less than half the undistorted section diameter of the O-ring. As shown, a plurality of coplanar circular ports 22 open into a groove 23 in a sleeve 7, the groove communicating with a port 24 in the valve casing 4. Further ports 12, 13 in the valve casing communicate with radial ports in the sleeve 7 so that movement of the valve 16 to left or right of the ports 22 connects the port 24 either with the port 13 or with the port 12. The movement of the valve is limited by stop elements 28, 29 engageable respectively with a cap 6 and an end wall 5 of the casing 4. Instead of being circular, one or each of the ports 22 may be elongated axially of the bore 21. The O-ring 20 is located, with clearance, between annular ribs on the valve 16. Minimum and maximum values are specified for the radial distortion of the ring 20 in relation to its section diameter.

Title: Improvements in gas governors
IPC: G05D16/20
Filed: 1934-08-27
Abstract: 443,570. Automatic control of fluid pressure. PARKINSON & COWAN (GAS METERS), Ltd., PARKINSON, B. R., and WALKER, H. L., Terminal House, Grosvenor Gardens, London. Aug. 27, 1934, No. 24599. [Class 38 (iv)] A fluid - pressure governor in which the governing valve is actuated by an independent power unit has the unit controlled by a pressure sensitive device acting through photo-elec. tric means. In the form shown, a butterfly valve in the fluid conduit is operated by a reversible electric motor d acting through gearing e. The electric motor is controlled by a pair of sensitive relays s<1>, s<2> connected in the anode circuits of a pair of thermionic valves v<1>, v<2>. The grids of these valves are connected to their cathodes by resistances x<1>, x<2> and through photo-electric cells p<1>, p<2> to the negative pole of the supply mains. The pressure sensitive device g operates a pivoted baffle so as to interrupt, more or less, the beam of light passing from a source o through a slot m to a pair of inclined mirrors t<1>, t<2> whereby it is reflected onto the photo-electric cells. When the pressure is low, light falls equally on both cells and both relays are energized to cause the motor to rotate in the direction necessary to open the valve. As the pressure rises the light beam falling on the cell p<1> is interrupted and the relay s<1> is de-energized causing the motor to stop. High pressure causes the baffle to obscure both cells thus de-energizing both relays and causing the motor to rotate the valve towards the closed position. A modified circuit arrangement includes an alarm device which is brought into action automatically upon failure of either photoelectric cell to effect actuation of its relay.
