A machine for welding wire mesh comprises two bus-bars extending across the machine, electrodes arranged on the bus-bars and current bridges above the electrodes, at least some of the electrodes being electrically connected to one or other of the bus-bars through a contact matrix held against the bus-bars and containing insulating and conducting parts arranged such that electrodes are connected to one or other of the bus-bars, the matrix being removable and replaceable. A machine for welding transverse wire 2, Fig. 1, to longitudinal wires 1 comprises electrodes 4 and current bridges 3 and two bus-bars 6, 7. The electrodes 4 are held by clamping parts 8, 9, Fig. 4, bolted together at 10 with the part 9 insulated against bus-bar 6 and a plate like contact matrix 5a between the contact faces of the bus-bars 6, 7, and the clamping part 8. The contact matrix 5a which comprises conductive regions and insulating regions (shown hatched) connect the electrodes so that in successive pairs one is in contact with bus-bar 6 and the other in contact with bus-bar 7. The bolt is loosened and the matrix is replaced by a different one which may be such that some electrodes are inoperative and larger bridges 3 are used. The matrix may be made up of a number of separate parts across the machine. In one modification the electrode 4, Fig. 5, is held by clamping parts 8, 9 and 11 by a bolt 10, the clamping parts 8 being of different lengths and being supported on an insulating plate 5, the plate and parts 8 forming the contact matrix. To change the matrix it is unbolted and another plate and parts 8 s bolted in position. In another modification the electrodes and clamping parts are attached to the insulating plate 5 to form a contact matrix and this may be replaced by another for different wire spacing.

Abstract: 491,936. Time switches; magnetic switches. CIANCHI, A. March 12, 1937, No. 7379. [Class 38 (v)] A magnet 17, situated outside a sealed container 4 and adapted to operate a switch within the container, is itself operated by a clockwork device 1 so that the switch is moved on or off at a predetermined time or times. In the form shown the switch is a mercury switch having a float 8 with an armature 10 that follows the movements of horse-shoe magnet 17. Downward movement of the float 8 causes mercury 9 to enter the float through a hole 11 and bridge electrodes 5, 6 connected to leads 13<1>, 14<1>. The container 4 is surrounded by a protective casing 12 embraced by the magnet 17 and inserts of magnetic material are provided in the casing 12 opposite the poles of the magnet. The magnet 17 is pivoted and moved by a cam 2 driven by the clockwork. In a modification, Fig. 2, clockwork drives two cams 2 which rock a magnet 17 so as to bring one or other pole towards the switch container moving the armature up or down. Members 21 of magnetic material retain the magnet in its end positions. Specification 485,564 is referred to in the Provisional Specification.

Title: Improvements in or relating to the Making of Joints in Oil-filled Conductors
IPC: H01R13/00
Filed: 1968-10-18
Abstract: 1,195,788. Direct connections. PIRELLI S.p.A. 18 Oct., 1968 [17 Nov., 1967], No. 49413/68. Heading H2E. [Also in Division B3] A method of making a joint between the core of an oil-filled cable and a second conductor by welding, allows continuous oil flow to be maintained during the welding process and yet prevents oil from reaching the point of welding. The oil-impregnated insulation 2 and outer protective insulation 3 of the cable are cut back to expose length 1 of stranded inner conductor core, and sealed by a winding 4 of adhesive tape, and an oil flow tube 16 fitted with sealing rings 9 is inserted into the oil-duct 5 in the core 1, the other end of tube 16 being inserted into the duct of the second conductor, which may be (as shown) a second cable core 1<1> or a cable end clamp or a cable sealing end, the design of the oil flow tube depending on the nature of the second conductor. A second layer 15 of tape is wound about the core 1 slightly spaced from the winding 4 and a circumferential vice 10 is clamped about these windings. An annular groove 12 on the inner surface of the vice is connected by hole 13 to union 14 to which a vacuum pump is connected so that oil seeping between the conductor strands is removed at this point. A similar arrangement is made at the other end of the oil flow tube 16. The joining zone Z where welding takes place is thus kept oil-free. When the welding has been completed the vices 10 and 10<1> are removed and the insulation is remade. In cables having more than one conductive layer in the core the outer layers are bent back and the above method is carried out on each layer in turn.

Abstract: 1,036,920. Purifying sea-water by freezing. NORRIS BROS. Ltd., and BRITISH PETROLEUM CO. Ltd. March 17, 1965 [Dec. 20, 1963], No. 50318/63. Heading F4H. In a process for obtaining potable water from sea-water by forming ice or a hydrate from the latter, refrigeration for the process is supplied by an absorption refrigerating system operated at least in part by the temperature difference between surface sea-water and water drawn from a depth considerably below sea-level. As shown, sea-water from considerably below sealevel is supplied through line 1 into a hydrateforming vessel 2 where it is contacted by liquid propane introduced through line 3. The propane-hydrate then passes through a washer 6 and vessel 7 in which it is decomposed by and condenses propane vapour from line 9. Potable water is withdrawn at 8 and liquid propane through line 3. Propane vapour and residual sea-water leave vessel 2 via lines 4 and 5 respectively and are fed to an absorber 10 in which the vapour is absorbed by a liquid propane-butane mixture, the absorber being cooled by the residual sea-water and fresh seawater tapped off from line 1. A pump 15 returns the propane-butane mixture to a rectification column 12 which is heated at its lower end by surface sea-water and cooled at its upper end by a condenser 20 which receives sea-water tapped off from line 1 via line 19. Waste heat from the plant may also be used to heat column 12 from which propane vapour passes to vessel 7 through line 9 and liquid propane-butane mixture passes to absorber 10 through line 11.

Abstract: 1,128,375. Sorbic acid and salts thereof. FARBWERKE HOECHST A.G. 26 Nov., 1965 [1 Dec., 1964], No. 50368/65. Heading C2C. Sorbic acid is prepared by pyrolysis of a polyester obtained from crotonaldehyde and ketene, the pyrolysis being effected under reduced pressure in the presence of 1-15 times the wt. of polyester of a solvent and in the presence of 0À5-10% by wt., based on polyester, of a secondary or tertiary aliphatic or alicyclic amine or a 5- or 6-membered heterocyclic amine, which may also contain oxygen as a hetero atom and be substituted by alkyl or aryl groups, the amine having a normal boiling pt. above 100‹ C. and being soluble in the polyester and/or the solvent. The preferred solvents are those boiling in the range 150-300‹ C. which also act as an entraining agent for sorbic acid, e.g. hydrocarbons, nitro derivatives of aromatic hydrocarbons and glycol ethers. In a modification of the process, the amine is used in quantities 1-15 times the weight of the polyester and also acts as the solvent, the product being the amine salt of sorbic acid which can be converted to alkali and alkaline earth metal salts by reaction with an hydroxide, oxide, carbonate or other alkaline salt of a Group I or II metal. It is preferred to effect the pyrolysis at 160-220‹ C. under a pressure of 10-50 mm. Hg. Amines employed in the examples are N-methyl octadecylamine, dioctadecylamine, dimethyloctadecylamine, trioctadecylamine, dicyclohexylamine, diethylene triamine, trimethylphenylethylene diamine, octadecyl piperidine, tricyclohexylamine and commercial mixtures of fatty amines.

Abstract: 504,458. Ticket-printing apparatus. A. E. G.-FAHRKARTENDRUCKER GES. Oct. 21, 1937, No. 28803. Convention date, Oct. 21, 1936. [Class 106 (iii)] In apparatus for printing tickets or vouchers corresponding to values which can be expressed as the product of two factors, one of a number of interchangeable printing plates which are selectively inserted into the apparatus is associated with each value of one of the factors and bears a mechanical representation of such value and such value is transferred by means of the mechanical representation to calculating mechanism on which the other factor is set manually,the calculating mechanism calculating the product of the two factors and setting it on printing mechanism by which it is printed on the ticket. In the construction shown - the setting members 19 of the calculating mechanism 14 are set to one of the factors (say cost per mile) by moving the corresponding setting lever 13 and consequently the associated template 16. The printing wheel 15 is simultaneously rotated. A ticket blank 23 is introduced into the slide 25 and the printer mechanism 2 is moved until the plate slide 21 is above the printing plate 3 corresponding to the other factor (say length of journey) which is drawn up from the holder 1 by the catch 6 on the lever 4 which is swung by a cam 7 about a shaft 5. The printing table 21 is brought towards the printing plate 3 by means of the plates 22 displaced by cams on the shaft 5 to put feeler pins 10 into contact with feeler pins 9 to set the second factor in the calculating mechanism 14 through Bowden wires 11 or other transmission devices. At the end of this movement of the printing table the ticket blank 23 contacts with the printing block 8 for the invariable text after which the printing- table is moved back into its initial position and the printing plate 3 is returned to the holder 1. The lever 24 is then moved over by a cam on the shaft 5 to bring the slide 25 in front of the printing wheels 15 and 12, the latter being set to the product of the factors from the calculating mechanism, and the printing table is moved a second time to print the ticket. Supplementary tickets for additional charges can be printed by the use of additional printing plates, each bearing a mechanical representation of the charge in question which is transferred to the calculating mechanism and multiplied by one by the setting lever 27.
