Patent GB-905431-A (GB)
Title: Improvements in hydraulic cement process
IPC: C04B7/45
Filed: 1958-09-22
Abstract: Hydraulic cement is obtained by initially establishing and maintaining a mass, at cement forming temperatures, of coarse product particles in a fluidized state in a reaction zone by upward flow of gas, charging fine particles of cement forming materials into the mass to allow formation of cement and its accretion on to the surfaces of the coarse particles, selectively withdrawing the accreted-on particles and discharging them as final product, whilst retaining the fine particles in the mass for cement forming reaction. The coarse particles are separated and discharged by passage downwardly through a restricted zone through which a gas is upwardly passed, the gas velocity being sufficient to entrain and carry back into the mass the fine but not the coarse particles.  The size of the withdrawn particles can be varied by varying the gas velocity. Specification 852,573 is referred to.

Title: Improvements in machines or apparatus for measuring and filling powdered, granulated, plastic or like substances into appropriate receptacles
IPC: B65B1/40
Filed: 1922-11-04
Abstract: 208,622. Young, B. Nov. 4, 1922. Operating clutches.-In a machine for filling materials into receptacles, the feeding devices aredriven through a friction clutch controlled automatically or by a pedal. The material, contained in a hopper 2, falls into a revolving cylinder 3 surrounding a fixed worm 25 which feeds it into a nozzle 26 in which a worm 29, secured to a diametric arm 3<a> in the cylinder 3 by a screw b, rotates to force the material into a receptacle 27. The cylinder 3 is driven from a pulley 9 keyed upon a sleeve 10 which rotates a face-cam 17 through gears 13, 14, 15. During rotation, adjustably fixed runners 19, 19<a> contact with the raised portions of the cam, and force the cam and associated gears to the left against the action of a spring 12, causing the pulley 9 and frictionclutch 8 to engage. The shaft 7 is rotated, and drives the cylinder 3 through gears 6, 5. When a sunken part of the cam 17 registers with the runners 19, 19<a> the clutch is disengaged. By adjusting the runners the amount of feed is regulated. The runners 19, 19<a> may be dispensed with, and the parts 8, 9 put in gear by a pedal 38 through links 40 - - 43. A table 30, on which the receptacle rests, descends as the receptacle fills and a lever 33 carrying a depending arm 37 depresses the pedal 38 and releases a catch rod 45, a spring 44 throwing the mechanism out of gear.

Title: Locking differential
Filed: 1954-10-20
Abstract: 788,105. Differential gear. THORNTON, R. F. Oct. 20, 1954, No. 30246/54. Class 80 (2). A planetary differential gear is rendered selflocking by coned friction clutch surfaces 94, 96 between the respective output side-wheels 74, 76, splined on vehicle axle shafts, and an input casing 10, carrying the usual ring gear, such surfaces being brought into engagement by complementary camming surfaces 24 on radial pins 34 &c., carrying the two pairs of planet pinions 58 &c., and in casing apertures 18 in which the pins have limited circumferential movement in response to transmitted torque, the camming surfaces being oppositely directed for pairs of pins on diameters at right-angles. In operation equalized forward or reverse torques cause the respective pairs of pins 34 &c. to thrust leftwards and rightwards on their planet pinions 58, and thence, through trackways 90, on the side wheels 74, 76 to engage the friction clutch surfaces 94, 96, thus locking the differential gear. During a turn the accelerating tendency of the outside wheel causes the planet-pins 34 &c. to advance relatively to the input casing 10, thus releasing the cammed clutch pressure for normal differential action as required. A central spring 72 pre-loads the clutch surfaces. In Fig. 8, not shown, the input casing is in three pieces permanently welded together and opposite planet-pins are integrally connected by offset central bridges.

Patent GB-322052-A (GB)
Title: Improvements in and relating to driving mechanism for sound reproducing machines
IPC: G11B17/00
Filed: 1928-10-19
Abstract: 322,052. Oyston, W. R. Oct. 19, 1928. Magazine gramophones; repeating-mechanism. -Relates to controlling-mechanism for automatic gramophones such as are described in Specification 304,070, and consists in providing on a spindle driven with the turntable a worm adapted to engage a toothed segment, whereby rotation of a shaft which controls the record transfer &c. is effected through levers connecting the segment to the shaft, the segment having a projection coacting with a stop automatically moved into and out of engagement therewith. In the machine shown, which is of the type described in the said prior Specification, a shaft 18, in conjunction with a subsidiary shaft, not shown, is adapted to be rocked by means of a lever 20, when the machine is started, to effect the transfer of a record from a magazine to a vertical turntable 8 and to perform various other operations including the positioning of the sound-box on the record. The lever 20 is connected by a link 24 to a toothed segment 22, which is adapted to gear with a worm 21 on an extension 19 of the turntable spindle. When the motor 4 is started, the worm drives the segment from the position shown in Fig. 2 to that shown in Fig. 3, so that the shaft 18 is rocked, against the action of one or more springs 113. At the same time, the slidable collar 27 of the centrifugal governor 10, driven from the turntable spindle, allows a counterweighted lever 26, bearing against it, to move so as to bring a stop 28 into the path of a lug 29 on the segment. The lug engages the stop when the segment has been moved so far that the crank-pin 23 is just beyond the dead-centre, and in this position of the parts the last tooth of the segment has passed clear of the worm 21. The shaft 18 remains in this partially rotated position, with the spring 113 in tension, until the end of the playing of a record, whereupon the motor is stopped and the governor 10 withdraws the stop 28 from engagement with the lug 29. This allows the spring 113 to return the shaft 18 to its initial position, and rotate the Segment 22 through the remainder of its revolution, the mechanism then being restored to the position shown in Fig. 2 ready for a new cycle of operations. A dash-pot or the like may control the movements of the oscillating parts.

Patent GB-1463343-A (GB)
Title: Automatic speed control system
IPC: G01S13/931
Filed: 1974-07-09
Abstract: 1463343 Automatic control of speed BENDIX CORP 9 July 1974 [30 July 1973] 30411/74 Heading G3R An automatic speed control system for a vehicle, using a desired vehicle speed and measured, speed dependent variables, is modified according to the difference between the measured variables and a predicted performance as calculated by a mathematical model from the desired speed. As shown the speed, acceleration and position relative to a preceding vehicle (i.e. range) are controlled by multipliers 26, 28, 24 respectively. A predicted speed from model 18 is calculated from the desired speed, and modified in multiplier 38 by the difference between the actual speed and the predicted value. Multiplier 26 receives the output of multiplier 38, and a signal dependent upon the vehicle speed error, to form one input to summer 31. This also receives the output of multipliers 28, 24 that are modified by multipliers 40, 36 according to the actual and predicted acceleration and position errors respectively. The output of summer 31 is used to vary the vehicle acceleration of braking as necessary to maintain the desired speed. This desired value is set by the driver (at 14), or according to external means e.g. in dependence upon weather conditions or traffic volume, and may be modified by the range as measured using radar. The control can be modified if the range falls below a "safe" distance (as set by vehicle speed) or if the rate of change of range exceeds a limit, in which case the modification is dependent upon the time that the limit is exceeded. The system is also described with reference to Figs. 3 and 4 (not shown).

Title: Improvements relating to the manufacture of fluorescent screens
Inventor: BAYFORD LESLIE JOHN CHARLES
IPC: H01J29/28
Filed: 1948-11-24
Abstract: A fluorescent screen for a cathode-ray tube is made by settling particles of a phosphor from a liquid suspension medium, e.g. water, on to the tube to form a fluorescent layer.  A solution of a film-forming substance, e.g. nitro-cellulose in methyl-ethyl ketone, is then applied to the surface of the water, and the solvent is evaporated so as to leave a film of the nitro-cellulose on the water, which is then removed by siphoning or decanting so that the film is applied to the phosphor layer. The film is then coated with aluminium applied by evaporation and the screen is heated to decompose the film, the metal coating thus being applied to the phosphor.

Title: Improvements in and relating to incandescent electric lamps
IPC: H01K1/54
Filed: 1932-10-31
Abstract: 394,557. Electric incandescent lamp filaments. BRITISH THOMSON-HOUSTON CO., Ltd., Crown House, Aldwych, London.- (Assignees of Andrews, M. R.; 1174, Van Antwerp Road, Schenectady, New York, U.S.A.) Oct. 31, 1932, No. 30556. Conven. tion date, Oct. 30, 1931. [Class 39 (ii).] In electric incandescent lamps wherein the lighting body or filament consists of a carbide of a refractory metal such as tantalum, hafnium, zirconium, &c., or mixtures of such carbides, a carbonaceous member is arranged as a source of carbon vapour to supply carbon to the lighting body during its incandescence, whereby dissociation of the carbide is reduced. The bulb is filled with an inert gas, such as argon or neon, at a pressure sufficiently high to retard thermal volatilization of the filament, the pressure of the filling being from one half to two atmospheres. In one form the lamp bulb 5, Fig. 1, contains a filament 7 of refractory carbide connected to leading-in wires 8, 9 by welding, pasting, or other means, and a small rod or filament 10 of graphite or other carbonaceous material is supported adjacent thereto by leading-in conductors 11, 12. The amount of carbon vapour evolved from the graphite rod is controlled by regulating the current passing therethrough, it being sufficient if the filament is maintained as the carbide containing the lower amount of carbon, In a modification the source of carbon vapour comprises an arc established between a pair of electrodes 13, 14, Fig. 4, of carbon or graphite. In a further modification the carbonaceous material is in the form of a core within a carbide shell, the composite filament being mounted within a bulb containing an inert gas. This filament may be made by means of an extrusion press having a plunger provided with a central core and a spaced annular portion, these two parts operating within separate enclosures respectively containing a carbon paste, such as graphite or charcoal and a binder, and a carbide or carbide-yielding material together with a suitable binder such as starch paste, the composite filament issuing from an orifice at the bottom of the press being baked before mounting in a lamp.
Patent GB-628401-A (GB)
Title: Improvements in or relating to the nuclear chlorination of aromatic carboxylic acids
IPC: C07C63/68
Filed: 1946-10-15
Abstract: Nuclear chlorination of aromatic carboxylic acids in which the carboxyl groups are nuclear and which have at least one nuclear hydrogen atom, is effected by treatment with an aqueous solution of hypochlorous acid at pH 2.0 to 6.0, preferably 3.5 to 5.0.  The aromatic acid may be generated in situ by the hydrolysis of such compounds as the acid anhydride or chloride or salt of the acid. It is preferred to use hypochlorous acid in a slight excess and in the form of metal salts.  Calcium and sodium are preferred hypochlorites, although potassium lithium, strontium, magnesium and barium hypochlorites are mentioned.  Aromatic acids mentioned are benzoic, phthalic, iso- and terephthalic, salicylic, toluic, p-acetyl-benzoic, anthranilic, o-benzoylbenzoic, o-, m-, and p-bromo- or chloro-benzoic, and anisic acids, dichloro-, dihydroxy-, and nitro-substituted benzoic acids and bromo-, chloro-, e.g. di- and tri-chloro, nitro-, and hydroxy-substituted phthalic acids.  Small quantities of alcohol or acetone may be added to effect solution of the aromatic acid.  The pH is maintained within the required range by buffer salts or by the addition of small amounts of a strong, e.g. hydrochloric, acid during the reaction, although when a dicarboxylic acid is chlorinated to the mono derivative the reaction produces its own buffer effect.  With a dicarboxylic acid the acid salt of the corresponding chlorinated acid may be obtained from which the free acid may be liberated.  In examples, phthalic anhydride is treated with aqueous sodium hypochlorite containing a small proportion of sodium hydroxide to yield (1) the mono sodium salt of 4-mono-chloro-phthalic acid which is converted to the free acid by treatment with calcium chloride and sulphuric acid; and (2) 4,6-dichloro-phthalic acid, the reaction being maintained within the desired pH range by the addition of hydrochloric acid; and in (3) phthalic anhydride treated with aqueous calcium hypochlorite, yields the calcium salt of 4-mono-chloro-phthalic acid, which yields the free acid on treatment with sulphuric acid.  In the Specification as open to inspection under Sect. 91 it is stated that the hypochlorite may be generated in situ, e.g. by adding chlorine to a solution of sodium hydroxide and in example (3) chlorine is passed through a solution of phthalic acid in sodium hydroxide, the mono-sodium salt of mono-chloro-phthalic acid thus obtained and the free acid liberated by treatment with hydrochloric acid.  This subject-matter does not appear in the Specification as accepted.
