Title: Improvements in the purification of vegetable or animal oils or fats
IPC: C11B3/02
Filed: 1930-09-08
Abstract: Olive, peanut, tall, and sesamum oils, and bone fat and other animal and vegetable oils or fats are desulphurized by heating in the absence of oxidizing agents with compounds or aqueous solutions of compounds of lead, copper, or nickel which are soluble in water or in the oil.  Specified compounds are salts or soaps, e.g. oleates, resinates, naphthenates, benzoates, enolates, e.g. acetyl acetonates, sulphur of copper or nickel, and lead nitrate.  The sulphate compounds or adsorptions formed may be removed by washing the oils with hot water which may contain salt or sulphuric acid or other electrolyte, or by filtration with the addition of bleaching earth or like filtering aid or of flocculating agents, e.g. gallic acid.  Or the sulphur compounds may be left in, insoluble harmless metal sulphides being formed on heating to 150 DEG  C. or higher.  The reaction may be accelerated by precipitating oxides or hydroxides from the salts of the above metals within the oil, or by adding reducing agents thereto.  The process may be preceded by known treatment with metals for removing sulphur compounds, or be combined with other methods such as treatment with bleaching earth, carbon, or silica gel, e.g. by mixing the metal compounds with adsorbents or sucking aqueous solutions thereon.  In examples: (1) 0,1 lb. of copper benzoate is stirred into crude bone fat at 60-70 DEG  C. until dissolved.  The fat may then be split, distilled, esterified, or otherwise worked in metal vessels without corroding them.  (2) 5 lb. of a 5 per cent solution of copper sulphate in water is stirred at 60 DEG  C. into 100 lb. of sulphur peanut oil, 10 lb. of water and 0,5 lb. of five per cent solution of tannin in water are added, and the temperature raised to 90 DEG  C.; the mixture is allowed to settle, the cuprous sludge drawn off, and the oil washed with water.  (3) 2 lb. of bleaching earth soaked with a solution of 0,5 lb. of sodium bisulphite in 1 lb. of water is stirred into 100 lb. of sulphur olive oil at 80-90 DEG  C., a solution of 0,5 lb. of copper sulphate in 1 lb. of water is stirred in, the temperature raised to 100 DEG  C. and the oil filtered.  Specifications 9292/92, 195,055, and 206,535, [all in Class 91, Oils &c.], are referred to.

Abstract: 1,155,483. Control systems for discharge lamps. D. F. WIDMAYER. 16 June, 1966. No. 26914/66. Heading H2H. [Also in Division G3] The current supply to a lamp, e.g. a neon, mercury, or fluorescent lamp, is regulated by a system comprising a first uncontrolled source providing the major operational power requirements of the lamp and a second controlled source providing an additional voltage, the first and second sources being interconnected by way of an inductance and the operation of the lamp being controlled by regulation of the second source. As shown, a fluorescent lamp 1 is supplied with D.C. derived from an A.C. source 6 by way of series connected rectifiers 8, 9, a choke 10, a resistor 11 and a polarity-reversing switch 7. The rectifier 8 receives its input from a transformer 13 connected directly to the source 6, and rectifier 9 from a transformer 16 having its primary winding connected to the source 6 over a bridge 18 associated with a thyristor 19 which can be phase-controlled to regulate the output of the rectifier 9. Firing signals for the thyristor 19 are produced by the control unit 22 in dependence upon a current feedback signal derived from the resistor 11, whereby the current through the lamp may be maintained at a selected value; a second feedback signal may be derived from a photo-electric or temperature sensor 42 positioned adjacent the lamp 1 so that the light output or temperature of the lamp may be maintained constant. The control thyristor 19 may be connected between the rectifiers 8 and 9 (Fig. 3, not shown). Circuits for controlling a plurality of lamps are described with reference to Figs. 4 and 6 (not shown.); these lamps may be operated in a particular sequence according to a programme input, or selected lamps may be operated at desired levels of illumination; further, the lamps may have predetermined spectral characteristics and may be periodically switched on-off according to a desired cycle, and the specification discusses the advantages of these arrangements in the fields of theatre lighting and plant growth.

Abstract: 409,205. Retractive switches. EVANS, C. J., and EVANS, S. C., 99, London Road North, Lowestoft. Oct. 5, 1933, No. 27410. [Class 38 (v).] Movement of the steering-mechanism of a vehicle to right or left closes or opens the circuits of a direction indicator, headlamps or dipping-mechanism, by means of a plunger switch or switches. In one form Fig. 1 the switch comprises a spring-pressed piston 23 slidable in a threaded tubular extension of a casing 22 and carrying at its inner end a plate 26. On this plate is mounted a contact ring 27 to bridge a pair of contacts mounted in a block 28 and connected with terminals 31 32. In another form the contact ring is divided into two portions each bridging its own pair of contacts. In the construction shown in Fig. 6 the terminals are arranged radially as at 47, 48 and connected with contacts 44, 45 normally bridged by the ring 46 carried by the plunger. In other arrangements both kinds of terminals may be provided that is, end terminals as in Fig. 1 and radial terminals as in Fig. 6 and these may be duplicated to provide for the opening of two circuits and the closing of the other two circuits whenever the plunger is moved to extreme position in either direction.

Title: Improvements relating to impulse transmitters
IPC: H04M1/677
Filed: 1933-10-05
Abstract: 405,589. Impulse transmitters. TELEPHON - APPARAT - FABRIK E. ZWIETUSCH & CO., GES., Charlottenburg, Berlin. Oct. 5, 1933, No. 27443. Convention date, Oct. 7, 1932. [Class 40 (iv).] In a dial-type transmitter, if the dial is retarded during its return movement, a mechanical operation takes place by which the emission of further impulses is prevented until the switchhook has been restored. This is done either by disabling the impulse circuit or by locking the dial against further rotation. In Fig. 2, the impulse cam shaft 2 is capable of a slight longitudinal movement and carries a disc 7 having a notch 8 normally in register with a projection 9 on a contact spring 12. During the return movement of the dial the shaft 2 is retained in the position shown by the pressure of the worm-wheel 5, but if the movement is retarded, the shaft is displaced longitudinally by a spring 1, and the engagement of the disc 7 with the projection 9 closes the springs 11, 12 to short-circuit the impulse springs. The spring 12 is latched by a detent 13 which is removed by a rocking arm 16 when the switchhook is restored. Alternatively, the spring 12 may hold open the impulse springs. In Fig. 13, upon displacement of the shaft 2, the disc 7 rocks a bell-crank lever 35 to bring a stop between two teeth of the wormwheel 5, further rotation being prevented until an arm 40 returns the lever 35 upon restoration of the switchhook. In Fig. 5; the disc 7 is provided with radial arms. If the shaft is displaced longitudinally, one of the arms strikes the upturned end 22 of a detent 19, and further rotation is prevented. The detent is withdrawn as before when the switchhook is restored. In Fig. 8, the shaft 2 carries weights 24 which swing outwardly under centrifugal force and shift the arms 26 clear of the end 22 of the detent 19. If however the movement is retarded, the weights fall and one of the arms 26 strikes the end 22, thus preventing further rotation. In a modification of these arrangements, instead of the dial being locked, the lever 19 is rocked to close contacts which shortcircuit the impulse springs. The governor weights may be used to control the blocking operation.
