Title: Improvements in or relating to electric circuit arrangements for operating electric discharge lamps on a.c.
IPC: H05B41/39
Filed: 1948-10-26
Abstract: 657,072. Control systems for space discharge lamps. GENERAL ELECTRIC CO., Ltd., and WILLIAMS, C. E. Oct. 26, 1948, No. 27823. [Class 38 (iv)] In a circuit arrangement for varying the discharge current through a hot cathode discharge lamp 7 by means of a variable ballast impedance, and comprising a heating transformer 5 for the lamp electrodes adequate control of the electrode heating is ensured by forming the ballast impedance in two parts comprising respectively a first part 3 connected between the transformer primary 13 and a supply terminal 1, and a second part 8 connected between the transformer and a lamp electrode, one or both parts of the ballast impedance being adjustable. The ballast impedance may comprise two resistances or two inductances or one of each, and variation of the inductance may be effected either by D.C. saturation or by an adjustable choke core. Simultaneous variation of the two parts may be effected by gauging or, in the case of inductances, by providing two choke windings on a common core. The first part of the ballast may be provided by the transformer leakage reactance and when step-up in voltage is required the secondary winding 16 may be included on the heating transformer and connected between the second part of the ballast and the lamp. The arrangement may be applied to series or parallel connected discharge lamps and in the latter connection each lamp should have its own second part but may share the first part of the ballast impedance. Specification 657,073 is referred to.

Abstract: 248,043. Lunge, E., and Courtaulds, Ltd. Nov. 20, 1924. Pumps for viscose; temperature of fluid, controlling. - The moving parts of the controlpumps 12 of an artificial silk spinning plant are immersed in a bath 13 of liquid such as will prevent the formation of a coagulated viscose film, and which may at the same time serve as a lubricant for the parts in question; suitable liquids are solutions of caustic soda and sodium carbonate, and the surface of the liquid is preferably protected from contact with the atmosphere by a layer of oil &c. Pipes 14 through which may be passed heating or cooling means, are provided in the tank 13 for the purpose of controlling the temperature of the liquid therein, and consequently that of the viscose; similarly the supply pipe 10 for the spinning solution may be passed through a jacket 11. By such means the temperature of the spinning solution may be controlled during its passage from the storage vessels to the spinning nozzles. This contact is particularly advantageous in an installation such as is described in Specification 248,046, in which the spinning solution is moved at high speed through a closed circuit along which the spinning nozzles are branched off uniformly. Specifications 248,038, 248,039, and 248,040 also are referred to.

A multi-colour printing machine comprises a number of successive units each adapted for single-colour printing and each driven by an electric motor Mt1-Mt3, and means are provided for synchronizing the speeds of the several motors. The first unit has a roll R1u which is coupled to the motor Mt1 and to the other rolls of the unit, the other units being similarly arranged, and each motor drives a tachometer generator Dt1-Dt3. The voltage of the generator Dt1 is compared with a reference voltage, and the error voltage is amplified for application to the field winding of the generator feeding the motor Mt1 In addition, the field winding of the generator supplying the motor Mt2 is controlled by the output of a synchronizing machine CT2, coupled to a shaft R2E of the second unit, and inter-connected with a synchronizing machine SG1 coupled to the shaft R1u. The output of the machine CT2 is a measure of the difference in speed between the shafts so that the motors Mt1, Mt2 are synchronized. The shafts R1u and R2E are also coupled to discs having indicators co-operating with photo-cells C1u and C2E which each emit steep-front pulses to an integrating circuit also connected to the tachometer generator Dt1 Dt2. The integrating circuit is effective for the intervals between the pulses and afford an indication of the total displacement between the rolls. The output of the circuit is supplied to a small motor Mc2 which is coupled to the motor Mt2 through differential gearing for correcting any displacement between the rolls of the first and second units.

The ratio of aluminium alkyl to aluminium alkoxide in the mixed starting material is preferably such that 50-70% of the organo groups attached to aluminium are alkoxide groups. This starting material can be obtained by oxidizing an aluminium alkyl in the absence of a catalyst using an oxygen containing gas. The alkoxides, alum (aluminium sulphate) by-product and detergent are also claimed when prepared from alcohols obtained by this process.

Abstract: 1320758 Recording apparatus N E G KAISER 10 June 1970 [10 June 1969] 28161/70 Heading G1J [Also in Division G2] The mean values of a plurality of functions are obtained as photographic representations by producing an optical display in which each amplitude value of each of said functions is represented by the distance of a luminous area of constant size and intensity from a datum line in a direction perpendicular to said line and producing from the display a photographic record wherein the exposed area corresponding with each function value is a line of the same predetermined length extending in said direction, whereby the variation in density of the exposed photographic record represents said mean value. The display is preferably produced on an oscilloscope screen 1 and is then imaged on a photographic plate 4 by a cylindrical lens 2 and an apertured diaphragm located between the lens 2 and plate 4. Several types of diaphragm are disclosed; one is rhombic in form with vertical and horizontal diagonals and gives an exposure most intense at its lowermost end diminishing linearly upwards. Thus for a plurality of the functions several exposures are made in superposition, the area of miximum density representing the mean value. Alternatively the display may illuminate a photographic plate through a series of laminae which give maximum transmission vertically but a linear diminishing with increasing angles in the horizontal plane, Fig. 5 (not shown). In a further embodiment the display is produced on an oscilloscope screen to which signals representative of the functions are applied, there being superimposed on each said signal an oscillatory signal of constant amplitude and having a frequency high in comparison with that of said signal the photographic record representing the desired mean value at its maximum density area.

Abstract: 279,515. Clay Reduction Co., (Assignees of Svendsen, S. S.). Oct. 25, 1926, [Convention date]. Silica; ammonium titanic or vanadic fluoride; ammonium silicofluoride; silicon fluoride ammonia.-Bauxite, felspar or other material containing aluminium is heated at 34-100‹ C. with a solution of ammonium fluoride or bifluoride to form ammonium silicofluoride, ammonium titanic or vanadic fluoride, and aluminium and other fluorides. The solution is dried and the residue is heated to 400-500‹ C. to volatilize silicon fluoride ammonia, and vanadium and titanium fluorides. The residue is treated with a reducing gas to aid volatilization and reduce iron to the ferrous state, and then with dry ammonia and hydrochloric acid gases at a temperature above that of the dissociation of ammonium chloride, so that the remaining non-volatile aluminium, potassium and other metallic fluorides become chlorides, and ammonium fluoride is formed. The vapours of aluminium chloride and ammonium fluoride pass off and are cooled first to 200-300‹ C. to separate the ammonium fluoride and then further to condense aluminium chloride. The latter may be heated with steam to produce alumina and hydrochloric acid, the alumina being subsequently heated to 1000‹ C. to dehydrate it. The fluorides first volatilized are treated with aqueous ammonia below 34‹ C., whereby silica gel and ammonium fluoride are formed. Any waste of fluorine is met by adding fluorspar. The non-volatile chlorides such as potassium chloride remain on volatilization of the aluminium chloride. Hydrofluoric acid may be used in place of ammonium fluoride.
