Title: Device for establishing and controlling the flow of a fluid under pressure from a container therefor
Inventor: ROUSSET RENE PAUL
IPC: F16K1/34
Filed: 1958-10-27
Abstract: 887,833. Valves. BRITISH OXYGEN CO. Ltd. Sept. 30, 1959 [Oct. 27, 1958], No. 34402/58. Class 135. A valve device for establishing and controlling the flow of a fluid under pressure from a normally sealed container 4, e.g. of liquefied fuel gas such as butane for use in stoves or lamps, comprises a tubulous piercing member 21 closed at one extremity the other extremity being adapted to communicate with fluid utilizing apparatus and having an aperture 23 extending from the bore to the exterior thereof, the piercing member being adapted at its closed extremity to pierce a plug 7 of resilient material provided on and normally sealing the container, so as to establish communication between the interior of the container and the bore of the piercing member through the aperture 23, the plug being adapted, when pierced, to maintain sealing contact with the wall of the piercing member, and means for subsequently adjusting the extent of penetration of the piercing member to control the flow. The tube 21 is carried in a bore 20 of a spring-loaded plunger 9 slidable in a body part 1 secured to a neck of the container, the bore 20 communicating with an annular recess 25 on the exterior of a stem of the plunger which has a screw-thread 26. This thread and recess 25 are covered by a tightly-fitting sleeve 27 of resilient material so that the fluid is forced to traverse the thread 26 which acts as a flow restriction. A circlip 16 locates the plunger during assembly of the body 1 to the container so that the plug 7 is pierced without flow commencing. A second body part 30 having an outlet 34 is then screwed on so as to abut the threaded end of the plunger stem and to adjust the device to a flow position.
Patent GB-1260132-A (GB)
Title: Improvements in apparatus for indicating liquid level
Inventor: TURNBULL JOHN HILTON
IPC: H01H35/18
Filed: 1968-07-19
Abstract: 1,260,132. Valves. G.K.N. SCREWS & FASTENERS Ltd. 24 June, 1969 [3 May, 1968; 19 July, 1968], Nos. 21001/68 and 34448/68. Heading F2V. [Also in Divisions G1 and H1] A device for indicating the level of oil in the oil sump of a motor vehicle engine comprises a float 21 movable in a chamber 10 connected via a conduit 14 with the inlet manifold, the float closing a valve arrangement when the oil is at the desired level 27 such that a vacuum is created above the float 21 so that it is suddenly urged upwardly causing its end 26 to actuate an electric switch, by separating contact spring blades 15 thereof, in an indicating circuit. Float 21 has a projection 22 of cylindrical stepped configuration, the portion 24 being a clearance fit in a passage 12 whilst the portion 23 sealingly engages the passage to provide closure of the valve arrangement when the oil is at the desired level. With oil below level 27, the portion 23 never reaches such sealing engagement. Inclined portion 28 moves into fluid-tight engagement with a countersunk part of passage 12, when the float is moved fully upwardly, to prevent oil passing through the passage into extension chamber 13. Chamber 10 communicates with the oil via a large diameter passage 19, Fig. 1, or by a conduit 34, Fig. 6, adapted to be inserted through the normal dipstick aperture in the vehicle engine cylinder block. To prevent unwanted operation of the sensing device during acceleration, an expansion chamber 29, Fig. 4 (not shown), is provided in conduit 14 and includes a ball valve 32 with a small bleed controlling fluid flow. Oil level is sensed only when the engine is started in the Fig. 6 embodiment. A further embodiment, preventing splashing oil from operating the sensing device, includes a time delay valve 35 at the bottom of chamber 10. With oil at the normal level 27, the delay valve piston 37 does not move appreciably to close passages 39, 41, because its movement is retarded by the restricted rate at which atmospheric air passes through the bleed aperture 40 into the cylinder 36, and accordingly oil is drawn up conduit 34 as in Fig. 6. With oil below the level of conduit 34 however, no oil rises up the conduit 34 to move float 21, but the suction in chamber 10 causes spring-loaded piston 37 to close the apertures 39, 41. This movement is retarded by bleed passage 40 and a dashpot (not shown). The  indicating circuit gives a visible or audible warning on opening or closing of contact blades 15.

Patent GB-441513-A (GB)
Title: Improvements in methods of obtaining vitamin concentrates
IPC: A61K31/59
Filed: 1934-12-03
Abstract: <PICT:0441513/IV/1> A vitamin concentrate is prepared from fish liver oils and the like by saponifying, adding a solvent for the unsaponifiable portion within the limit that the soap solution can take up, and then extracting the unsaponifiable portion with an additional quantity of the solvent in counter-current.  In an example, cod-liver or other oil or fat mixed with alcohol is saponified with caustic soda at 70 DEG  C., then cooled to 50 DEG  C. and diluted with 25 per cent alcohol.  Ethylene dichloride is then added in sufficient quantity to raise the specific gravity to 1,024 or as much as the solution will take up, and the unsaponifiable portion is then extracted by means of additional ethylene dichloride in counter-current.  The soap solution is supplied from a tank A to the bottom of a column 14 containing Raschig rings and initially filled with solvent.  Ethylene dichloride is supplied at the top of the column from a tank B.  The extract is collected in a receiver C and the exhausted soap solution in a tank D.  The extract may be concentrated in vacuo, washed with water or with a solution of a salting-out agent such as sodium chloride or sulphate or calcium chloride, and any remaining solvent may be removed by distillation at a temperature not exceeding 60 DEG  C. Instead of ethylene dichloride, other solvents such as ether, petroleum ether, or carbon tetrachloride may be used.

Title: Improvements in the manufacture and production of delustred rayon
IPC: D06M13/08
Filed: 1933-12-09
Abstract: In the production of delustred artificial silk there is added to the solution to be spun both chlorinated diphenyl ("arochlor") and an inert organic material of an oily or waxy nature.  Examples of such inert materials are petroleum oil, petroleum jelly, and paraffin wax. The amount of chlorinated diphenyl employed is preferably from 0.2 to 10 per cent, and of inert organic materials, from 0.5 to 15 per cent, calculated with reference to the finished yarn.  In an example, to viscose prepared in the normal manner, there is added 0.075 per cent of chlorinated diphenyl and 0.2 per cent of mineral oil, together with a small amount of sperm oil as emulsifying agent.  The spinning and finishing takes place in the usual manner. Specification 384,224 is referred to.
Patent GB-752549-A (GB)
Title: Improvements in or relating to electric motor control systems
IPC: B60L7/04
Filed: 1954-12-01
Abstract: 752,549. Control of D.C. motors. WESTINGHOUSE ELECTRIC INTERNATIONAL CO. Dec. 1, 1954 [Dec. 7, 1953], No. 34779/54. Addition to 748,120. Class 38(3) The dynamic braking-circuit referred to in the parent Specification is modified by the inclusion of an additional braking resistor 90 which is connectable in series with the accelerating resistor R2, the value of this additional resistor being such that it prevents an excessive braking- effort when the motors are operating at high speed. When the master controller is moved from its "off" position to its first braking position, the resistor 90 is included in the braking-circuit and the motors 1-6, now acting as series generators, will develop appreciable armature voltages only if the motor-speed exceeds a critical value, whereupon a relay BRV responds to open the circuit at contacts 23<SP>1</SP>, 22<SP>1</SP>, and 55<SP>1</SP>. The system includes a time-delay relay because it is necessary to wait for a short period to ascertain whether the initially established braking- circuit will result in the development, of appreciable motor-voltages. The timedelay relay is energized in the first braking-position of the master controller, after which a sluggish-acting braking contactor 23<SP>1</SP> operates finally to energize con-, tactor RC'. The time-delay relay is then de-energized and the relay drops out after a period enabling the voltage-responsive relay BRV to be actuated, provided that the prevailing motor-speed is such that it will respond. When the time-delay relay completes its drop-out movement, and the relay BRV has not responded, a line switch 32<SP>1</SP> is closed to short-circuit the resistor 90 so that the motor-voltages now increase at a gradual rate and the maximum safe voltage is not exceeded. An over-voltage relay OV is connected across armatures 4, 5, 6, to protect against excessive voltage which may be developed after the braking-circuit has been established: An interlock contact is provided on the master controller to open the braking-circuit in the event of premature movement from the first to the second braking position. In order to detect an accidental earth in the motor circuits, particularly during an attempted dynamic braking operation, a portion of a highresistance earth-lead 93 is connected through rectifier 94 to a relay GR which breaks the motor circuit if accidental earthing occurs on the positive or negative sides of the point A5<SP>1</SP>.

Title: Improvements in or relating to disc brakes, particularly for motor vehicles
IPC: F16D55/14
Filed: 1964-08-25
Abstract: 1,082,822. Disc brakes. H. KLAUE. Aug. 25, 1964, No. 34815/64. Heading F2E. A vehicle disc brake comprises a rotatable brake disc 6 which is formed with an annular outwardly opening U-shaped peripheral groove, brake segments 36 and 37 carrying friction linings 39 and 40 disposed in said groove, and a wedge member 34 acting via rollers or balls 35 in inclined ramps or recesses associated with the brake segments to initiate braking by urging the segments apart towards the respective walls of the groove, movement of said wedge member being in a direction chordwise of the disc. The wedge is actuated by an hydraulic piston cylinder assembly 27, 30 which is carried by an elongated member 18 fixed by bolts 17 to a stationary brake carrier 15. The brake segments are also supported on this carrier by spring metal backing plate members 22 and 23 which are secured to said segments by rivets 38 and bolted to the member 18 at 19. Said backing plate members have punched-out flanges 22<SP>1</SP>, 23<SP>1</SP> which complement projections on the brake segments to form the ball or roller ramps. Provision of the backing plates enable the brake segments to be formed as light metal die castings. In the embodiment of Figs. 4-6 (not shown), the brake segments and wedge member are carried by a pair of removable pins (45, 46) in an inverted channel section brake carrier (43) straddling the disc periphery. An hydraulic piston/ cylinder actuator (59) is mounted at one end of the said carrier and a removable cover (63) at the other. By removing the cover and then said pins, the brake segments and wedge member may be removed circumferentially. Tension springs (53) disposed axially between the brake segments retain the said segments, wedge member and their associated balls or roller together as a unit. A spring (62) disposed between the end of the wedge member and the cap ensures return of the former after brake release. In a further embodiment, Figs. 7-10 (not shown), the brake segments and wedge are mounted in a light metal cast C-shaped brake carrier (81) which is bolted to a fixed sheet metal bracket (77) by studs (79) passing through open-ended slots therein. The carrier has an integral extension 86 containing the actuating piston of the wedge member. When nuts engaging the studs are released, the carrier and brake segments can be removed radially as a complete unit. Radial ribs are provided on the disc for stiffening and cooling purposes.

Title: Improvements in methods of preparing ortho-disubstituted ú=-aminobenzoic acid derivatives
IPC: A47L5/28
Filed: 1960-10-12
Abstract: Compounds of the formula <FORM:0896720/IV (b)/1> (wherein R1 is hydrogen or alkyl, R2 is hydrogen or acetyl, R3 is halogen or alkyl, R4 is alkyl, Y is -NH- or -O-, n is 2 or 3 and R is a tertiary amino radical) are prepared by reduction of compounds of the formula <FORM:0896720/IV (b)/2> followed, when required, by alkylation and/or acetylation, and also, if desired, by the formation of acid-addition salts or quaternary ammonium derivatives of the products.  These processes may be combined, in turn, with the preparation of the compounds of the second general formula above by heating a 1-bromo-2-R3-4-nitro-6-R4-benzene with a cuprous cyanide-pyridine (1 : 1) complex salt to give a 1-cyano-2-R3-4-nitro-6-R4-benzene hydrolysing this to the corresponding amide and thence to the corresponding acid, converting this to the acid halide (e.g. by the use of an inorganic halide such as thionyl chloride), and reacting this with the appropriate diamine or amino-alcohol HY(CH2)n-R. The reduction process of the invention is desirably accomplished either by catalytic hydrogenation using Raney nickel, or, when R3 is a halogen, by the use of powdered iron and hydrochloric acid.  The subsequent alkylation may be effected with an aliphatic aldehyde with subsequent catalytic hydrogenation of the Schiff's base at first produced, and the acetylation of the free or mono-alkylated amino compounds may be effected with acetic anhydride or acetyl chloride. Hydrolysis of the substituted p-nitro-benzonitriles to the amides and then the acids may be effected with sulphuric acid and nitrous acid respectively. Examples are given.  1 - Bromo - 2 - R3 - 4 - nitro - 6 - R4 - benzenes are prepared from the corresponding p-nitroanilines, by diazotization and reaction with cuprous bromide.  Specifications 768,770 and 791,599 are referred to.

Title: Improvements in or relating to magnetic data storage systems
Inventor: SPENCER ROLF EDMUND
IPC: G11B5/004
Filed: 1954-12-07
Abstract: 782,582. Electric digital-data-storage apparatus. ELECTRIC & MUSICAL INDUSTRIES, Ltd. Dec. 5, 1955 [Dec. 7, 1954], No. 35336/54. Class 106 (1). In a magnetic storage system information is stored at a first series of discrete spaced points or regions of a magnetizable medium, and then further information is stored at at least one other series of discrete spaced points or regions interposed between the points or regions of the first series. As described, a rotatable drum 1 coated with magnetizable material such as gamma-ferric oxide, comprises a shaft 3 carrying an arm 8 with a blade contact 10 cooperating either directly or capacitively with the pointed ends of a series of stator contacts 6. A slip-ring 9 and spring contact 11 are connected to an amplifier 12 which is also connected to a magnetic writing head 14. Data to be entered in a series of spaced points round a track of the drum, is set up in registers 29a, 29b, 29c ... &c., which are scanned in succession by the rotating contact arm 8 and, after amplification, corresponding " write " signals are delivered to the head 14. Before the next recording, adjustment of a knob 27 to another graduation on a dial 28 enables the selection of interposed digit spaces for a subsequent recording. A further knob 20, gears 22, 23 and a threaded rod 19, enable the selection of any track on the drum. In practice these mechanical devices would normally be replaced by electrical means. For reading out stored information the same, or an additional head may be used to feed signals to the same, or an additional, amplifier. A separate rotor could be used for reading out, so as to overcome the slight angular difference between reading and writing. Helical tracks, tapes, discs and belts, are mentioned as magnetic recording surfaces. Specifications 707,634 and 753,333 are referred to.
Patent GB-475993-A (GB)
Title: A process for the preparation of fertilisers containing citrate-soluble phosphate
IPC: C05B13/02
Filed: 1936-12-24
Abstract: Products useful as fertilizers and comprising double salts of the type CaKPO4 are obtained by calcining mineral phosphates with trialkaliorthophosphates at moderate temperatures which may be below 1100 DEG  C.  For each part of P2O5 in the mineral phosphate a quantity of trialkali-phosphate containing more than 0,5, preferably about 0,8 parts of P2O5 must be employed.  In place of trialkali phosphate, mixtures of alkali metaphosphate or pyrophosphate or mono- or di-alkali phosphate with alkali carbonate or alkali silicate may be used. Salts such as potassium chloride or magnesium chloride which assist the reaction may be added to the initial mixture and enable the reaction temperature to be lowered to 900 or 800 DEG  C.  By subjecting the mineral phosphate to a pretreatment with P2O5, for instance by using the waste gases from a phosphorus furnace, less trialkali phosphate may be used; the said pretreatment may increase the P2O5 content of the mineral by as much as 20 per cent.  Reaction may be effected in a rotary or shaft furnace or in a Dwight-Lloyd blast apparatus, and the initial mixture may be moulded if desired.
