IPC: H02M7/06
Filed: 1969-11-03
Abstract: 1290885 Converting A R DAVIS 3 Nov 1969 [12 Nov 1968 (2)] 53834/69 Heading H2F [Also in Division H1] An inductive winding 35 with integral terminals 36, 37 is formed by spirally cutting side walls 22-25 of a tubular member 30 which is a good thermal and electrical conductor and may be of aluminium. The member surfaces are then treated by anodizing or with epoxy resin to insulate the turns from each other and the resilient winding is axially compressed. Cooling fins 26-28 may extend along the winding 35 in which case they are also spirally cut (Fig. 3, not shown). The wall 24 of the member 30 is cut back at both ends forming notches 51 to receive a pair of U-shaped laminated cores, the legs of which abut at the centre of the member 30 with mica spacers (67, Fig. 1, not shown) between the abutting core ends. The terminal 37 is extended and carries a device such as a controlled rectifier in thermal and electrical contact therewith. Two tubular members 120, 121 may be fitted side by side on one pair of core members held together by a strap (164, Fig. 11, not shown) which is secured by a clip or by adhesive. The magnetic core is potted by pouring silicone rubber into the tubular members after closing their bottom ends by means of an insulating piece (166, Figs. 10, 12, not shown) held in place by screwed prongs 167, 168. An air-cored arrangement is also envisaged, see Fig. 13, not shown. A printed circuit board 171 is bolted to the tubular members and carries a firing circuit to control solid state rectifiers (143, 144, Fig. 9, not shown). Prongs 174-176 are connected to the firing circuit and receive a control signal from a preset board, not shown. Applications such as rectifiers, inverters, D.C. to D.C. converters, and choppers are suggested. An embodiment is suggested in which the tubular member is bent to form a toroidal winding.

Abstract: 1296865 Generation and electro-dialysis of hydrogen ions and hydroxyl ions ASAHI KASEI KOGYO K K 15 Dec 1969 [16 Dec 1968] 61030/69 Heading C7B Hydrogen ions and hydroxyl ions are generated and electro-dialyzed from water by passing a direct electric current through an aqueous solution or suspension of at least one polyelectrolyte incapable of passing through ion-exchange membranes and selected from (1) water-soluble polyelectrolytes having negatively charged fixed groups and (2) finely pulverized water-insoluble polyelectrolytes having negatively charged fixed groups, and obtaining hydrogen ions H<SP>+</SP> out of the aqueous solution or suspension by electrodialysis of the H<SP>+</SP> ions through a cation exchange membrane placed on the cathode side of the aqueous solution or suspension and OH<SP>-</SP> out of the water by electro-dialysis of the OH<SP>-</SP> through an anion exchange membrane placed on the anode side of the aqueous solution or suspension. The aqueous solution or suspension may also contain polyvalent metal ions such as Ca<SP>++</SP>, Mg<SP>++</SP>, Fe<SP>++</SP>, Fe<SP>+++</SP>, Cr<SP>++</SP> or Cr<SP>+++</SP>. These may be added initially, intermittently or continually. The soluble polyelectrolyte may be polystyrene sulphonic acid or its salts, acidic sulphuric acid ester of polyvinyl alcohol or polyvinyl sulphonic acid. The insoluble electrolyte may be a finely powdered cation exchange resin. Fig. 1 illustrates electro-dialysis in apparatus comprising alternate anion and cation exchange membranes 3 and 4 with supply of:- water and polyelectrolyte through pipe 9 to compartments 5; water or acidic solution from pipe 10 to compartments 6; water or alkaline solution from pipe 11 compartments 7 and salt solution from pipe 12 to compartments 8. The cathode may be graphite Fe, Ni or stainless steel. The anode may be graphite, Pt, Ti, Ta or Zr coated with Pt. During the electro-dialysis acid is generated in the compartments 6, alkali in the compartments 7 and water is consumed from the compartments 5. By the process (i) NaOH and HCl can be produced from NaCl and (ii) NaOH and CH 3  COOH can be produced from CH 3  COONa. In the latter application and for the decomposition of a salt of a weak base the apparatus can be simplified. In decomposing CH 3  COONa, those anion exchange membranes can be omitted whereby the salt and acid compartments become combined. In decomposing a salt of weak base, those cation exchange membranes can be omitted whereby the salt and alkali compartments become combined. Specified cation and anion exchange membranes are prepared from polymeric styrene-divinyl benzene as matrix to which sulphonic groups or quaternary ammonium groups have been respectively introduced.

Abstract: 1297822 Windscreen washing system TRICO-FOLBERTH Ltd 17 Aug 1971 [18 Aug 1970] 39768/70 Heading A4F [Also in Division H1] A windscreen washing system includes a control lever 26b which may be moved in one mode to operate a washer pump and in a second mode to operate a wiper motor, the second mode including both a stable and an unstable "on" position for the wiper motor. To operate a washer pump, lever 26b is pivoted vertically in Fig. 2 about pin 27, and the rear end 26a of the lever forces piston 14 of a pump 10 (Fig.3) downwards against spring 23 to eject washing liquid through exit 19 via non return valve 20. If it is desired to use an electric washer pump instead of mechanical pump 10 contacts 72, 74 at the top of the pump may be utilised, the mechanical pump 10 then functioning merely as a spring biasing means. To operate an electric wiper motor, the lever is rotated in a horizontal plane in Fig.2. The lever is mounted on a plate 25 which is journalled about the pump body 12 by hub 60 and which carries a contact 37 at the end of a leaf spring 36. Plate 24 is fixed to the pump body 12 and carries fixed contacts 38, 39, 40 and 40a. Plate 24 also carries protuberances 42 which co-operate with a protuberance 41 on leaf spring 36 to lift contact 37 vertically as it moves between fixed contacts. The plate 25 includes a skirt 44 having indexing notches 45, 46 and 46a and a ramp 47 which co-operate with a spring biased ball 49 mounted on the plate 24 between shoulders 48. The switch is shown in Fig.4 in the neutral position, contact 39 being unused. On rotating the lever and plate 25 clockwise, contacts 40 and 40a are operated in turn for two speed wiper motor control, the ball 49 co-operating respectively with notches 46 and 46a. If the lever is rotated anti-clockwise, contact 38 is operated to run the wiper motor, and ball 49 rides up ramp 47, so that on release of the lever, spring 50 immediately biases the lever and plate 25 back to the neutral position. Hub 60 of plate 25 is fastened to the pump body 12 by plate 62 and screws 67 engaging bosses 63 on the pump body 12, the bosses cooperating with recesses 65 in hub 60 to limit rotation of the switch assembly. Instead of an electric wiper motor, a compressed air, vacuum or hydraulic operated motor may be used, and the switch assembly shown in the figures may operate a solenoid valve or be replaced by a valve.
