Title: Improvements relating to the production of aluminium soaps
IPC: C07C51/41
Filed: 1943-09-07
Abstract: In the manufacture of aluminium soaps having gelling power towards hydrocarbon oils by an aqueous precipitation process wherein a water soluble salt of aluminium is mixed with either a water-soluble salt of an organic acid reaction component or the organic acid itself in the presence of a water-soluble alkali hydroxide or carbonate under conditions of agitation and at a temperature compatible with a melted condition of the organic acid employed, the process is effected under conditions which are not substantially akaline, in the presence of a hydrophylic colloid dispersed in the bath, whereby a proportion of the colloid becomes incorporated with the precipitate so as to persist in the dried product.  The organic acids are aliphatic or cycloaliphatic and contain not less than six carbon atoms in the molecule, specified reactants being caproic, lauric, stearic, palmitic, oleic, ricinoleic acids or naphthenic acid or mixtures of such acids.  Specified protective colloids are: gelatine, glue, albumen, gum arabic, polyvinyl alcohol, methyl cellulose, isinglass, soluble starch, agar agar and saponin.  Advantageously the bulk of the precipitation is effected under conditions of non-alkalinity of the bath, optionally in the presence of a buffer reagent such as sodium acetate.  The precipitate at first formed is preferably allowed to mature, with continued agitation of the bath for a period of several hours before filtration, and meanwhile a part of the total quantity of alkali necessary may be added.  The organic acid and alkali reactants are preferably added to an already prepared bath of the aluminium salt reactant, the addition being preferably in the form of a substantially neutralised aqueous solution of an alkali soap of the organic component.  The product is desirably such as readily forms a gel when dissolved in pure benzene, containing a little phenol, by a specified procedure.  When it is aluminium stearate it may suitably contain a proportion of free stearic acid. In an example, an aqueous solution of aluminium sulphate is treated with an aqueous glue solution at 60 DEG C. and to the stirred mixture at 60 DEG C. is added a soap solution formed by dissolving commercial stearic acid in an aqueous mixture of acetic acid and caustic soda, the pH being approximately 3.5-4.0 while the bulk of the precipitable hydrated alumina stearate is formed as a highly dispersed precipitate of fine granular texture.  More but smaller quantities of precipitate are then formed by adding 10 per cent. aqueous soda ash until the pH is 5.2 and the stirring of the mixture is continued for about 5 hours at 60 DEG C. with periodic addition of further small quantities of soda ash to maintain the pH at 5.2 and below 5.3 until precipitation is complete.  In further examples the same procedure is followed except in that the factors pH value and nature of colloid are varied within the scope of the invention.  The Provisional Specification comprises the optional use of protective colloids in general, casein being additionally specified.

Title: Improvements in or relating to automatic warning devices
IPC: B60R25/10
Filed: 1953-05-26
Abstract: 755,840. Theft alarms. PHILLIPS, F. W. July 26, 1954 [May 26, 1953], No. 14688/53. Class 118(1) [Also in Group XXXVII] A theft alarm for use with a motor vehicle comprises two pendulums, an outer one consisting of two depending arms 61, 62, Fig. 4, carried by a pivot block 55 and insulated therefrom by a layer 60, and a inner one consisting of a bob 65 carried by wire arms 67 which are pivoted in the block 55 at a point below the central axis thereof. Contacts mounted on the bob 65 co-operate with contacts mounted on the arms 61, 62 so that on disturbance of the pendulum system the contacts are closed to actuate the alarm. A block 64 is supported upon a screw 66 fitted between the lower ends of the arms 61, 62; thus by adjustment of the block 64 the inner pendulum may be centralized with respect to the outer one. The device is employed in the circuit shown in Fig. 1. The inner pendulum 30 is connected to earth and the outer pendulum 31 through a parallel arrangement of relay coils 35, 36 and heating coil 29 to a source of power through contacts 18, 20 of a key-operated switch 14. A resistor 34 is arranged in parallel with the pendulum device in order to increase the sensitivity of the relays when the switch 18, 20 is closed. With this switch closed, movement of the pendulums caused by a person tampering with the vehicle on which they are mounted effects the operation of the relay 35 which is self-holding by virtue of its being connected to earth through its contacts 32, 33. Relay 36 is simultaneously operated, thus closing contacts 23, 24 connected in the circuit of the vehicle's horn. The current flow through coil 29 effects the heating of bimetallic strip 28 so that after the horn has sounded for a certain period the contacts 26, 27 open and the alarm ceases. The contacts close again after the strip has cooled and the alarm recommences should the original initiating cause still be present. When the vehicle's ignition is switched on by the closure of switch 12 a solenoid 40 is energized and forces its armature 41 (see also Fig. 4) against the outer pendulum thus preventing movement thereof. An alternative alarm arrangement may be provided by the circuit shown in Fig. 1 by operating the key-operated switch 14 to close the switch contacts 15, 19 so that when the ignition switch 12 is closed the relay coil is energized thus closing the contacts 23, 24 and sounding the alarm.

IPC: H01F27/14
Filed: 1965-04-07
Abstract: 1,072,528. Transformer breathers. DRYVENT Ltd. May 25, 1966 [April 7, 1965; May 27, 1965], Nos. 14821/65 and 22624/65 Heading B1L. [Also in Division H1] In a dehydrating breather for an oil-filled transformer, the desiccant is regenerated by heating while air is being expelled from the transformer. The desiccant or air being expelled may be heated by the transformer oil to supply all or part of the required heat or heating may be achieved using either the transformer-oil or an independent heat source (e.g. electrical) operated by a pressure switch . which will be actuated by the increase in gas pressure caused by a restricted outlet valve. Fig. 2 shows a desiccant charge 8 in a container having inlet 13, from the transformer conservator tank. Air is admitted from the atmosphere through valve 15 and leaves thereto through valve 16. The space 10 surrounding the desiccant container and inlet 13 contains oil which passes to and from the transformer via passage 11 and to and from the conservator tank via passage 12. When the oil in the transformer is being heated, heated oil passes from the transformer to the conservator tank and in passage heats the desiccant and the inlet 13, while air is expelled from the conservator tank and passes to the atmosphere at 16 after regenerating the desiccant 8. When the transformer oil cools. relatively cool oil returns to the transformer from the conservator tank, thus sucking air in at valve 15 through the cooled desiccant to be thus dried. In Fig. 3 (not shown), the oil jacket is omitted, and expelled air is heated by passage through a coil (23) in transformer oil (24) before entering breather (25) to regenerate the desiccant therein. In Fig. 4 (not shown) air passages to desiccant (32) directly by tube (33) to and from the space (34) at the top of transformer (31). Conventional oil cooling tube (30) passes through the charge (32) and the circulation of oil therethrough when the transformer becomes heated is sufficient to heat the desiccant for the regeneration thereof.

Title: Hydraulic clutch
IPC: F16D25/0638
Filed: 1959-05-01
Abstract: 895,061. Friction clutches. BORG-WARNER CORPORATION. May 1, 1959 [May 14, 1958], No. 15001/59. Class 80(2). A multiple disc clutch 50 between driving and driven shafts 10, 18 is engaged when fluid under a relatively high pressure is admitted through shaft ducts 14, 88 to move a plug valve 94 rightwards against the bias of a spring 96 from the position shown so that a port 110 is opened for the admission of fluid under pressure to a working chamber 78 between a reaction plate 38 fast on the driven shaft and a first piston section 54, the first piston section being bolted to a second piston section 52 on the opposite side of the reaction plate and the compositite piston defining, as well as the working chamber 78, two secondary working chambers 70, 72. As pressure builds up in the working chamber 78, the combined piston 54, 52 moves leftwards against the bias of a clutch disengaging spring 125 to clamp the discs 50 together. Fluid under pressure in the working chamber 78 leaks through a bleed hole 112 in the reaction plate 38 to the outer working chamber 70. As the composite piston 54, 52 moves leftwards, the working space 72, which is full of fluid, is reduced in volume, and this fluid is forced through one-way flap valves 132 into the working chamber 70. When the pressure in the inlet duct 14 is allowed to fall to a nominal value, the plug valve 94 is returned by its spring 96 to the position shown, when ports 104, 106 co-operate with the port 110 to allow venting of fluid under pressure from the working chamber 78 to an exhaust passage 138 in the driven shaft 18. At the same time, passages 114, 116 in the plug valve 94 co-operate with passages 120, 124 leading to the working chamber 72, so that fluid under the nominal pressure now in the shaft duct 14 is supplied therethrough as the volume of the working chamber 72 increases during the clutch disengaging rightward movement of the composite piston 54, 52. When clutch disengagement has been completed, the three working chambers 78, 70, 72 are full of fluid, so that immediate response is obtained on initiating clutch re-engagement by increasing the pressure in the shaft duct 14. The working chambers 70, 72 are so dimensioned that the effects of centrifugal force reacting upon the fluid contained therein is balanced out, whereby centrifugal actuation of the clutch is prevented.

Title: Improvements in or relating to cable fault locating apparatus
IPC: G01R31/08
Filed: 1947-06-06
Abstract: 624,148. Locating faults; resistance measurements. WESTERN ELECTRIC CO., Inc. June 6, 1947, No. 15023. Convention date, June 29, 1946. [Class 37] The invention is concerned with locating a fault in a coaxial line, particularly a fault consisting of a sliver of metal from the inner or outer conductors protruding into the intervening dielectric. According to the invention, a calibrated potentiometer 62 is connected across e.g. the inner conductor 67 of the line, and a high D.C. potential is applied between the inner and outer conductors to cause arcing at the fault, so that a Wheatstone bridge is formed consisting of portions of the potentiometer 62 and the portions of the inner conductor divided at the fault, the bridge being balanced by adjustment of tap 60 and the device indicating balance having a filter to eliminate undesirable harmonics of the arcing current so as to facilitate the exact balancing of the bridge. The fault is located by comparison of the portions 64, 60 and 60, 70 of the potentiometer with the length of the cable. As shown, the high D.C. potential is produced by taking oscillations from 12, 13, applying them through a delay device 26 (to avoid loading valve 44 before its filament has been heated), rectifying them at 44 and applying them to charge condenser 55 until it reaches a potential sufficient to arc at a fault 76 in the line 67, 68. The outof-balance currents at 100, 101 are applied to milliameter 110 over a transformer 102 whose secondary winding is short-circuited so as to form a low-pass filter.

Title: Manufacture of polysulphides of aromatic carboxylic acids and esters thereof
Filed: 1928-05-22
Abstract: 291,100. Eder, R. May 27, 1927, [Convention date]. Carboxyarylpolysulphides.-Aromatic mercaptocarboxylic acids or esters are treated with sulphur halides, whereby polysulphides are produced in which two aromatic nuclei, each containing a carboxylic group are connected by a bridge of 3 of 4 sulphur atoms. With sulphur dihalides, trisulphides are obtained, while sulphur monohalides give tetrasulphides. The esters may also be produced by first treating the murcaptocarboxylic acids with sulphur halide and then esterifying by usual methods. The reaction with the sulphur halide is preferably effected in the presence of indifferent organic solvents such as ether, chloroform, acetone, methylenechloride or petroleum ether and instead of the free mercaptans, metal compounds thereof, such as alkali mercaptides may be used. According to examples, dibenzoicacid-3 : 3<1>-tri- and tetra-sulphide, dibenzoicacidethylester-3 : 3'- tri- and tetra-sulphide, disalicylicacid-5: 5<1>-tri- and tetra-sulphide and disalicylicethylester- 5 : 5<1>-tri- and tetra-sulphide are prepared by treating the corresponding mercaptocarboxylic acids or esters with sulphur mono- and di-chlorides in the presence of solvents. The disalicylicethylester-5- : 5<1>-tri- and tetra-sulphides may also be produced by esterifying the corresponding free acids, for example the carboxylic acid polysulphides may be refluxed with absolute alcohol containing hydrochloric acid. The esterification of dibenzoicacid-3 : 3<1>-tri- and tetra-sulphide is also referred to. The properties of the following carboxylic acid polysulphides are tabulated : dibenzoicacid - 2 : 21 - trisulphide, dibenzoicacidethylester-2 : 2<1>- and 4 : 4<1>-trisulphides, disalicylicacidallylester-5 : 5<1>-tri- and tetra-sulphides, and dibenzoicacid-2 : 2<1>- and 4 : 4<1>-tetrasulphides. 3-Mercaptobenzoic and 5-mercaptosalicylic acid ethyl esters are prepared by esterification, in the usual manner of the parent acids. The Specification as open to inspection under Sect. 91 (3) (a) comprises also the production of polysulphides, in general, or aromatic carboxylic acids or esters. This subject-matter does not appear in the Specification as accepted.
