Abstract: 734,426. Luminescent material. GENERAL ELECTRIC CO., Ltd., HUNT, B.. E., and McKEAG, A. H. Oct. 8, 1953 [Oct. 31, 1952], No. 27477/52. Class 39 (1). In a barium-strontium disilicate activated by lead the molecular ratio of silica to other oxides is in the range 2: 1 to 3: 1 (e.g. 2.2) and the molecular ratio of strontia to baria is not greater than 20: 80 (e.g. 5: 95). The lead forms 0.1 to 10 per cent (e.g. 2.6 per cent) of the total material calculated as oxides, and activates the material to emit long-wave ultraviolet light when excited by light of 2537 A wavelength or electrons at 10,000 volts. Fluxes of alkaline earth halides may be used. In an example the starting materials are milled for 2 hours with about 4 per cent of a first flux of barium fluoride, fired in air for 3 hours, cooled, milled with 5 per cent of a second flux of hydrated barium chloride for ¢ hour, refired for 2 hours, cooled, milled for 1 hour, and refired for 2 hours, all firings being at 1050-1150‹ C. The material may be used as the first layer of a double-layer cathode-ray tube screen. The Provisional Specification describes the preparation of materials emitting blue light.

Title: Improvements relating to machines for coating or making sandwich biscuits
IPC: A21C15/00
Filed: 1945-10-19
Abstract: 603,396. Coating biscuits. MACFARLANE, R. F., and BAKER PERKINS, Ltd. Oct. 19, 1945, No. 27576. [Class 28(i)] In transferring the stencil shaped composition cream layer to a biscuit by means of a stencil drum 1 which applies a stencil of cream to an endless band 2 for transferring to the biscuit, e.g. as described in Specification 486,861, the stencil layer is severed from the band 2 by a heated wire or thin strip 16, which cuts the layer from the band and alows it to be deposited on the biscuit. The wire &c. 16 is heated to about 160‹F. either by carrying current directly, or indirectly by locating the ends within resistance heating coils. The biscuit conveyer is formed of a series of linked'supports each to carry a biscuit stripped from the underside of a pile 13 by spring depressed posts 6, raised when passing under the pile. The posts may form a " V " shape to deal with round, oval &c. biscuits. The biscuits then proceed to the deposit position and receive the cream, after which they may proceed to a second biscuit magazine 14 where a second biscuit is drawn out by the posts 6 from the bottom of a pile to make a sandwich biscuit. A handwheel 36 adjusts the height of the ramps 12. The cream carrying band 2 at the deposit station passes over a cambered plate 20 where the wire strips off the deposit to drop on to each biscuit, the camber depressing the wire to its own shape so as to make a clean cut. The pressure of the stripping wire is maintained against the band by a spring 23, which can be released by displacing a knob 24 so that the spring ceases to act on the bent levers 21. The stencil carrying band 2 may be replaced by a metal stencil carrying drum. The band may be raised or lowered at the deposit position. The cream containing drum 1 may be.fed by a piston pump from a hopper and may have steam or electric heating out of contact with the cream. Electrically heated scrapers 28 keep clean both the drum and the band 2. The biscuit holders of the conveyer are kept clean by another electrically heated scraper 29. To synchronise the biscuit accurately with the delivery of a stencil deposit the biscuit conveyer can be moved bodily to right or left by a handwheel 35 moving the end bearing of the conveyer sprockets simultaneously to left or right by means of a nut and screw 32.

Abstract: 1,118,461. Fuel injection pumps; fuel injector. VYSKUMNY USTAV PRISLUSENSTVO MOTORVYCH VOZIDEL. June 30, 1965 [July 3, 1964], No.27670/65. Headings F1A and F1B. The plunger of a combined fuel injector and injection pump is actuated on the delivery stroke by hydraulic pressure and on the return stroke by a spring, the return or suction stroke length being controlled by throttling the outlet from the actuating end of the plunger cylinder. The actuating end of the plunger may be larger in diameter than the delivery end. Each pump/injector is connected to a separate outlet 79 of a rotary distributor type pump having a distributing passage 78 which communicates with each of the outlets in turn as the rotor 65 rotates. Also formed in the rotor in the same transverse plane as the passage 78 is a groove 86 which separately communicates with each of the outlets 79 in turn before the passage 78. The groove 86 is connected through a throttle 90 to a tapered recess 89 on the periphery of the rotor 65 and a sleeve 93 having radial passages 98 corresponding to the passages 79 is slidable over the recess. The position of the sleeve 93 controls the period that the recess 86 communicates with the low-pressure outlet 99 and hence the return stroke of the injection plunger. The distributor channel 73 communicates with a spring-loaded accumulator piston 80, controlling the pressure build up, the axial position of which is adjustable by means of shims 85. Injection is terminated by the opening to spill passages of the delivery side of the injection plunger, followed by the actuating end.

Filed: 1946-09-16
Abstract: 621,880. Aerating sewage. TRIGGS, W. W. (Dorr Co.). Sept. 16, 1946, No. 27690. [Class 111] In the method of treating sewage by the activated sludge process and by aeration, in which the air bubbles formed also produce agitation of the liquid, the air is supplied by water-jet injectors sumberged below the surface of the liquid. In one form the apparatus is supported by a vertical tube 1, Fig. 1. having a water inlet 3 and lateral pipes 6, the tube 1 being surrounded by a packet 4 having an air inlet 5 and lateral pipes 7, a water-jet injector 8 being connected to each pair of lateral pipes as shown. The apparatus may have alternatively one only, or a plurality, (e.g., four), of injectors, equally spaced radially about the central tube. When used in the arrangement of Fig. 3 the return sludge is used as water feed for the injectors. The sewage flows from a main 12 into an aeration tank 10 in which are installed one or more injector-aerators 11 connected to a sludge-return pipe 15 and air feed pipe 16 respectively. A settling tank 18 to which the sewage overflows, is provided with a chain-conveyer 19 which moves the settled sludge to a sump 21 whence it is pumped back to the aerators. The water feed to the injectors may alternatively be pumped directly out of the aerating tank, the return sludge then being mixed with the fresh sewage. For large tanks water or return sludge may be supplied through a pipe 21, Fig. 4, downcomer 22 and header 23 resting on supports 24 near the bottom of the tank, and connected at intervals to transverse feed pipes 28 having injectors 29. Air from inlet 25 is similarly fed to the injectors 29 by transverse feed pipes immediately below the pipes 28. In another arrangement the header 27 is vertically above the header 23.

Title: Improvements in or relating to the treatment of palm oil
IPC: B01D17/00
Filed: 1953-10-08
Abstract: Concentration of carotene in palm oil is effected by forming a thin film of palm oil defined by opposed surfaces of heat-conductive inert material closely and substantially uniformly spaced from 0.01 to 0.15 inch apart, maintaining a temperature gradient across the film of oil, and accumulating and withdrawing from the film a carotene-enriched fraction concentrated by thermal diffusion adjacent to the cooler surface. A lighter coloured fraction may be simultaneously withdrawn from adjacent to the hotter surface, advantageously at more than ten times the rate of withdrawal of the carotene-enriched fraction. Preferably the palm oil is previously dehydrated and has added to it an inert viscosity-reducing agent and an antioxidant, though some antioxidant effect is in any case produced by tocophenols which accumulate with the carotene adjacent to the cooler surface. Examples illustrate the various features of the invention, employing film thicknesses varying from 0.019 to 0.044 inch, and using in some cases chlorobenzene as diluent or rice bran extract as antioxidant.ALSO:Palm oil impoverished in carotene and therefore lighter in colour than the starting material is obtained by forming a thin film of crude palm oil defined by opposed surfaces of heat-conductive inert material closely and substantially uniformly spaced from 0.01 to 0.15 inch apart, maintaining a temperature gradient across the film of oil, and accumulating and withdrawing from the film the lighter-coloured fraction concentrated by thermal diffusion adjacent to the hotter surface. Preferably the palm oil is dehydrated before treatment.ALSO:Butter and margarine are coloured, and their Vitamin A content increased, by adding thereto a carotene-enriched fraction obtained from palm oil by a thermal diffusion process (see Group IV (b)).ALSO:As a colouring for butter and margarine is employed a carotene-enriched fraction obtained from palm oil by a thermal diffusion process (see Group IV (b)).

Abstract: 1,194,403. Hair waving hood. DEL LABORATORIES Inc. 15 June, 1967 [9 Sept., 1966], No. 27719/67 Heading A4V. [Also in Divisions H3-5] A hood for use in accelerating the permanent waving of human hair comprises a thermostatically controlled flexible electric heating element 18 sandwiched between two flexible imperforate insulating helmets 12, 14 which are stitched together, and heat separated from the outer helmet 14 a mass of thermal insulation 24, 26. In use, the hood is plugged into a power supply until the temperature of the inner helmet lies between 150 and 190‹F., when the temperature of the outer helmet 14 is less than 120‹F., whereupon it is unplugged and placed on the client's head which has previously been treated with permanent waving solution, e.g. an aqueous solution of ammonium thioglycolate and ammonium hydroxide. The heat stored in the insulating layers 24, 26 is transferred to the client's hair by radiation and greatly reduces the time of treatment. The heating element may be a woven or knitted element but as shown comprises a wire wound about a flexible asbestos core and sheathed in asbestos felt. The heating element is stuck or stitched to the inner helmet 12 in the form of a meandering pattern. The insulating heat storage layer 24 is made of sisal felt and the layer 26 of glass wool. The plug 32 is attached to the hood by a short lead 30 from which the hood is suspended when plugged in. The centre of gravity of the hood is such that its mouth is closed by the wall when suspended, thereby reducing heat loss.

IPC: H04N5/04
Filed: 1959-08-18
Abstract: 955,660. Automatic phase control systems. ASSOCIATED TELEVISION Ltd. Aug. 18, 1960 [Aug. 18, 1959], No. 28227/59. Heading H3A. Phase modulation of the line synchronizing pulses of a television waveform reproduced from a tape-recording machine is corrected by applying the reproduced pulses and reference line pulses to synchronize oscillators 7, 3 feeding a phase comparator 9, whose output phase modulates an oscillator 11 in an opposite and compensating sense relative to the phase error. The oscillations are then amplitude modulated at 13 with the reproduced and error bearing television waveform and demodulated to produce a signal free of phase error. Alternatively, the output of a second phase detector may control a variable gain amplifier between the first phase detector 9 and the phase modulator 10. The reference signal may be dispensed with and oscillator 3 phase-controlled by a " flywheel " circuit at the average phase of the reproduced line pulses from a phase comparator to which the said pulses and " flywheel" oscillations are applied. In addition to the above the D.C. output of comparator 9 may control the speed of one or more of the drive motors of the television recorder as by being applied to one or more stator windings to act as an eddy current brake, or the output from comparator 9 may phase modulate a servo control signal driving the motor. Alternatively, in a video tape recorder, the speed of a motor driving the recording head may be indicated by a photocell or by contacts, and compared with the television waveform to be recorded to derive an error signal phase-modulating the waveform to compensate undesired phase modulation.
