Title: Improvements in or relating to processes for the purification of etched electrodes
IPC: H01G9/04
Filed: 1937-12-22
Abstract: 508,075. Cleaning by electrolysis. SIEMENS & HALSKE AKT.-GES. Dec. 22, 1937, No. 35554. Convention date, Dec. 22, - 1936. [Class 41] The surfaces of electrodes, particularly electrodes for electrolytic condensers, which are roughened by etching to increase their effective surface area, are cleansed by connecting the electrode as a cathode in a cleansing electrolyte liquid which is substantially free from constituents of the etching bath used prior to cleansing. Preferably, the cathode and anode spaces are separated by a suitable diaphragm, and the process may be supplemented by. a further washing both of anode and cathode spaces, using a liquid free fromforeign ions, such as distilled water, electro-osmotically purified water, glycerine or glycol. The ions removed from the electrode surface may be removed by a colloidal or colloidal-chemical process, which may comprise one of the four following processes, if the acid used for etching is hydrochloric acid: (1) chemical deposition of the chlorine ions freed by the cleansing ; (2) conversion of added substances to complex compounds by the freed ions ; (3) conversion of substances of ionic character into non-ionic substances; (4) absorption of the freed ions and separation into flocculent form by means of colloids. Process (1) may be carried out by adding an appropriate salt or compound to the bath, e.g. silver oxide, mercurous nitrate, lead nitrate or acetate to precipitate silver, mercurous, or load chloride, or by using a counter-electrode of an appropriate metal, e.g. silver, antimony, lead, or bismuth, to give silver chloride, antimony oxychloride, lead chloride, or bismuth oxychloride. Process (2) may be carried out by adding platinum chloride, chromium hydroxide, palladium ammonium-chlorido or palladious chloride, and process (3) by adding benzene diazonium hydroxide to the anode compartment, which is converted to benzene diazonium chloride by the freed chlorine ions, which immediately loses nitrogen to give chlorbenzene. Process (4) may be carried out by adding colloidal ferric hydroxide, aluminium hydroxide, chromium hydroxide, titanium dioxide, or zirconium dioxide. Diaphragm materials specified are leather, parchment paper, viscose, and material sold under the Registered Trade Mark " Cellophane."

Shallow trays are successively loaded with weighed vegetables at a loading station, carried by a conveyer to a table at a wrapping station where each tray is wrapped manually with slightly self-adhering plastics sheet, and conveyed through an oven to seal the wrapper, means being provided for stopping the conveyer when a tray is positioned over the table (to permit the manual wrapping) and for restarting the conveyer when the tray is removed from the wrapping station. In an embodiment, Fig. 1, two endless belt conveyers 2 carry loaded trays 10 from the loading station 4 to the wrapping station 6 where the belts pass over tables 12, and where a photo-electric cell 14 and lamp 16 co-operate to switch off the electric motor drive of the respective conveyer when a tray arrives. Reels 18 of plastics sheet are disposed with their axes parallel to the direction of movement of the trays, and each sheet is passed under the respective table 12 where its end is gripped by an operator at the side of the table remote from the reel. The end of the sheet is drawn over the tray and tucked under the far side, the tray is lifted and moved towards the operator to enclose the tray, and moved downwards to sever the sheet on a heated wire 22, and the edges of the sheet are folded under the tray and the tray moved on to a hotplate 23. The tray is replaced on the conveyer 2 downstream of the wrapping station 6 and is delivered to a further conveyer 24 which conveys it through the oven 8 for sealing and shrinking of the wrapper. Alternatively, the tray may be placed after wrapping on the further conveyer which may then extend between the two conveyers 2. Alternatively, a single conveyer may be used (and the further conveyer dispensed with), each wrapped tray being stationary in the oven when the conveyer is halted. The photo-cell may be replaced by a pressure-sensitive or ultra-sonic device. In another embodiment, the operator faces along the conveyer, and the reel 18 &c. extends across the conveyer.

Abstract: 829,891. Hydraulic shock absorbers. CANADAIR Ltd. Nov. 20, 1957 [June 25, 1957], No. 36166/57. Class 108(3) [Also in Groups XXXI and XXXIII] An articulated vehicle (see Group XXXI) comprises two or more units 5, 6 connected by a ball joint 7 about which relative roll and pitch is controlled by a system 8 of shock absorbers 24 connected to the units in V formation by ball joints at 27 and 28. Each shock absorber 24 is a cylinder 29 containing hydraulic fluid, closed at its open ends by blocks 33 and moving over a piston head 32 on a rod 31. The head 32 has two transverse ports 40 and 41 'and two check valves 42 and 43 that control the flow of fluid between the cylinder bore one either side of the piston head 32 and a control chamber 34 bored axially in the rod 31. The chamber 34 moves over a control needle 35 in the form of a double piston 35a and 35b connected by a tapered mid-section 36, 37, 38. When the vehicle is on level ground the piston 32 is at the centre of its travel and is central with respect to the control needle 35. Movement of the piston in either direction causes a flow of fluid from one side of the head 32 to the other through the ports and valves 40 to 43. At the same time the increasing diameter, due to taper, of the control needle where it passes under the ports 40 and 41 causes a rapid build up of resistance to the motion, which is finally checked completely when either of the piston portions 35a or 35b seals the ports.
