Title: Improvement in or relating to the modification of aluminium base alloys containing silicon
Inventor: BHATNAGAR SURENDAR SAHAI
IPC: C22C21/02
Filed: 1961-09-25
Abstract: Aluminium base alloys containing at least 2% silicon are modified to improve the microstructure by adding to the molten alloy 0.05% by weight sulphur as the modifying agent.  If the alloy is hypereutectic, i.e. contains silicon in excess of 11.7% as primary grains, the effect of sulphur is enhanced by also adding, e.g. 0.015%, of phosphorus preferably as phosphorcopper. The modifying agents may be wrapped in aluminium foil and plunged in the melt of aluminium-silicon alloy heated to 720-760  DEG C. Prior art discloses the adding of sodium to the melt of hypo-eutectic aluminium-silicon alloys. Specific final alloy compositions disclosed fall within the range: - 4.12-23.50% Si, 0.65-0.72% Fe, 0-0.108% Cu, 0-011% P, 0-0.012% S, balance Al.

An adjustable stop arrests the gate in alignment with the passage, whereupon the spindle takes up against a spring 35 backed by the washer 37 to force the closure members apart. These members can accommodate to their seats by the natural resilience of the spindle 31.

Abstract: 766,291. Carburetters. SOLEX. Nov. 26, 1954 [Nov. 30, 1953], No. 34367/54. Class 7 (3). In a carburetter comprising a constant level overflow chamber fed with fuel by means of a pump, as well as a lower chamber adjacent to the constant level chamber and adapted to receive directly the excess fuel overflowing the overflow edge or weir of the constant level chamber, this lower chamber communicating when it contains a certain quantity of fuel with the feed of the pump, the upper part of the lower chamber is fixed to the bottom of the constant level chamber and is in contact therewith over a relatively small area so as to limit the transmission by conduction of heat to the lower chamber. The nozzle 14 draws its supply from an overflow chamber 5 to which fuel is supplied by a pump 7 past a calibrated orifice 9. When there is sufficient fuel in the overflow chamber 16 the valve 21 cuts off the pump from the reservoir 18 and fuel is drawn from the chamber 16. The valve 21 may be operated by a diaphragm. The chamber 16 may be connected to the air intake through the tube 17 or it may be vented through the tube 10. Any suitable fuel nozzle system may be used. An emulsifying tube 15 is provided with holes (not shown) in its sides. A lever 37 operated either by the driver or automatically controls the starting device.

IPC: C01D7/35
Filed: 1953-12-11
Abstract: Sodium carbonate monohydrate, having substantially all its crystals in the form of rectangular parallelopipeds, whose longest axis is not more than twice the next longest axis at right angles, preferably cubes, instead of the usual form of bipyramidal orthorhombs whose longest axis is usually 2 1/2 times the next longest at right angles, is produced by hydrating soda ash in the presence of an organic sulphate, or sulphonate, or a water-soluble salt thereof, as crystal modifying agent.  Light ash at 160-200 DEG C. and excess, say 20-40 per cent of the ash, water at 50-90 DEG C. containing 0.05-0.3 per cent of the modifying agent may be fed to a cylindical, rotary mixer and maintained at 90-107 DEG C. until crystallization occurs.  The resulting crystals may be passed to a rotary drier from which dense anhydrous sodium carbonate is obtained.  Suitable organic sulphates and sulphonates include RO-SO2-OH or R-SO2-OH where R is a hydrocarbon radical of at least 6 carbon atoms, and salts may be those of alkali metals and ammonium.  Specified modifying agents are:-benzene and naphthalene sulphonic acids, p-sodium sulphonates of toluene and xylene, isopropyl naphthalene sodium sulphonate, 2, 3-diisopropyl benzene sodium sulphonate and the corresponding diethyl, dimethyl, and dipropyl compounds, kerosene sulphonic acids and their salts, sodium octyl sulphate, sodium lauryl sulphate, and sodium cetyl sulphate, and the corresponding ammonium and alkylol-amine salts, sodium benzyl sulphonate, sodium salt of phenyl propyl sulphuric acid, dioctyl sodium sulphosuccinate, and the corresponding diisobutyl, diamyl, and dihexyl esters, naphthol sulphonic acids, naphthylamine sulphonic acids, and Turkey-red oil.

Abstract: 962,166. Crystallizing. PHILIPS ELECTRICAL INDUSTRIES Ltd. Oct. 10, 1960 [Oct. 13, 1959], No. 34621/60. Heading BIG. A crystalline powder 3 is placed in boat 2 in the furnace tube 1. The furnace 4, which may heat by convection, radiation or high frequency induction, maintains a local heated zone of high temperature which can be shifted longitudinally by motor 5. The powder in the area of broken lines passes into the vapour phase and is deposited in the cooler area as crystals 10. A slow inert gas current from inlet 8 helps to convey the vapour. Because of the movement of the furnace the distribution of impurities in the product will ideally be the same as that of the starting material. The powder in a boat may be replaced by a rod of material. Crystal growth may be stimulated by a seed crystal or a 'cold finger'.

Title: Process for the production of oximes of cyclic ketones
Filed: 1961-09-28
Abstract: Oximes of cyclic ketones containing at least nine carbon atoms in the ring, e.g. cyclododecanone oxime, are produced by reacting the ketone with a hydroxylamine salt, e.g. the sulphate or chloride, at temperatures above room temperature in an aqueous medium having a pH value of 3 to 8 in the presence of a dissolved emulsifier or solid insoluble emulsifier.  Emulsifiers specified are pentaoxyethyl coconut oil amine, tetrapropylene benzene sulphonate or its sodium salt, fatty alcohol sulphonates, the reaction product of 1 mol of coconut oil alcohol with 15 to 25 mols of ethylene oxide, barium sulphate, calcium phosphate and barium or calcium silicates.  The emulsifiers are conveniently used in a concentration of 0.05 to 5%. The concentration of the hydroxylamine salt solution generally lies between 0.5 and 30% and a slight excess of the theoretical quantity is preferably used. The oximation is preferably carried out between the melting point of the cyclic ketone and 134 DEG C. more especially between 80 DEG C. and 100 DEG C.  The aqueous medium may also contain, besides water, an organic solvent miscible with water, e.g. MeOH.  The ketone may be used dissolved in a solvent, preferably a solvent immiscible with water, e.g. benzene or gasoline.  Examples are furnished.

[Class 40 (v).] In a signalling system in which secrecy is obtained by scrambling or inverting the lowfrequency signal currents and by varying the carrier frequency, the rate of variation of the carrier frequency is low, being of the order of one oscillation per second, so that speech distortion is avoided. The range of variation to be effective is equal to the band width of the signal, or if the signal is subdivided into bands, to the width of one of these bands. The receiver is arranged to be sufficiently broadly tuned to accept the carrier and sidebands at all frequencies transmitted.

Abstract: 1,181,328. Taxi meters. KIENZLE APPARATE G.m.b.H. 24 July, 1968 [1 Aug., 1967], No. 35243/68. Heading G4T. A control arrangement for actuating a taxi meter comprises means for generating a signal on detecting a passenger within a taxi, signal processing means and timing means to delay actuation of a taxi meter a predetermined time after the passenger has entered the taxi. Primary coils 10, 12, concealed in the back and front seats of a taxi respectively, are fed a continuous A.C. signal from an oscillator circuit 14. When a passenger sits down, the primary coil 10 or 12 approaches a corresponding secondary coil 11 or 13 in which an increased current is induced. This is fed to A.C. amplifier circuits 19 or 20, rectifiers 21 or 22, and filters 23 or 24, before entering a threshold control circuit 25. If the signal is above an upper predetermined level or if the signal falls below a lower predetermined level indicating a failure in the circuit, a signal 25a is fed to an RC time delay circuit 26 which delays the signal for twenty five seconds. A trigger circuit 27 accepts the signal and starts a taxi meter 28 only if the taxi meter is not operating. A manual switch is provided to actuate the taxi meter if necessary.
