Title: Improvements in or relating to electrolytic capacitors
IPC: H01G13/00
Filed: 1966-03-23
Abstract: 1,145,061. Capacitors &c. CIBA Ltd. 23 March, 1966 [25 March, 1965], No. 12874/66. Heading H1M. [Also in Division C7] In a process for forming electrolytic capacitors, pellets of porous sintered valve metal, e.g. titanium, zirconium, tantalum, or niobium, are anodized in such a manner that the surfaces of the outer regions (the pore surfaces in the regions nearer to the outer surface of the pellet) are formed to a higher voltage than the surfaces in the inner regions (the pore surfaces further from the outer surface of the pellet), whereby the oxide layer formed in the outer regions is thicker than the oxide layer formed in the inner regions of the pellet. This may be effected by first oxidizing both inner and outer regions to the lower voltage and then further anodizing the surfaces of the outer regions to a higher voltage. Prior to the second anodizing step the pellet may be impregnated with a substance insoluble in the electrolyte, and soluble for instance in lipophilic solvents, e.g. a wax, paraffin wax, anthracene or stearin, the impregnant being removed from the pores of the outer regions thereof which are then further anodized. The impregnant may then be completely removed by solvent extraction, e.g. using benzine or chloroform.

Filed: 1971-05-04
Abstract: 1286220 Waste-disposal units SO M A T CORP 4 May 1971 [20 July 1970] 12899/71 Heading B2A A waste-disposal unit comprises a chamber 14, Fig. 1, a disc impeller 15, having upwardly projecting shear teeth 22, a perforated cylindrical member 12 closely surrounding the impeller, stationary shear members 24 having an edge cooperating with an edge of the shear tooth 22, a baffle 20 to deflect material inwards towards the cutting edges of the stationary shear members, and interrupter members 25 mounted on the inner wall of the perforated cylindrical member 12 to cooperate with the tooth 22, and projecting towards the central axis of the chamber 14. The interrupter members 25 facilitate loosening cutting and removal of fibrous material which tends to collect between the shear teeth and the perforated cylindrical member. The included angle A, Fig. 2, between the leading edge of each tooth 22 and each tooth 24 is from 35‹ to 55‹, and thus permits a progressive cut. A specific clearance can be set by adjustment of teeth 24. Similar progressive cutting is provided between members 25 and teeth 22, the included angle B, Fig. 2 varying between O‹ and 35‹ and preferably 16‹ to 35‹.

Title: Clock striking mechanisms
IPC: G04C21/10
Filed: 1971-05-04
Abstract: 1343959 Striking clocks JAZ SA 4 May 1971 [11 May 1970] 13060/71 Heading G3T In a striking mechanism having a counting wheel 20 driven by an electric motor 29 which is energized via contacts 44, 45, the contacts are opened to stop the motor after the desired number of strikes by axial movement of a spindle 24 which is rotationally driven by the motor 29 and carries a worm 23 meshing with a gear wheel 22 which is fast with the counting wheel 20. Striking is initiated by a cam 5 which is rotated once per hour by a clock movement and co-operates with a lever 7 pivoted on a support 9. When the lever 7 is allowed to drop from the chain-line position under the force of spring 8, its arm 7b engages a toe 51 of stop lever 14 and causes the latter to pivot clockwise about a spindle 15 against a spring 16, thus disengaging lever arm 14b from notches 19 of the counting wheel 20. This frees the wheel 20, and the spindle 24 is displaced to the right under the bias of spring 47, the worm 23 acting as a rack on the wheel 22 and thus rotating the counting wheel 20 in the direction of arrow F. The spindle displacement also allows the contacts 44, 45 to close, thus energizing motor 29 which drives the wheel 20 in the same direction until the arm 14b engages the next notch 19 therein to lock the wheel. Further rotation of the motor then acts to displace the spindle 24 to the left, opening the contacts 44, 45 and de-energizing the motor. The number of strikes is thus determined by the spacing of the notches 19. The sounds are produced by hammers 36, 37 which are raised by cams 30, 31 on the spindle 24 and which strike bells (38, 39) Fig.2 (not shown). The mechanism may be made inoperative to silence the strikes by rotation of a member 55 to keep open the contacts 44, 45. Striking may be temporarily silenced, e.g. at night, by a further lever (not shown) which acts on the hammers 36, 37. The mechanism may be arranged to strike only one bell at the half-hours or hours by means of an additional cam (52), Figs. 3, 4 (not shown) which rotates with the cam 5 and renders the hammer 37 inoperative. A disc 48 rotating with the wheel 20 carries graduations which correspond to the notches 19 and are visible through an aperture (49) in frame plate 1 so that the mechanism may be set by inspection to line up with the indicated time. This is achieved by manual operation of the lever 14 via an external push-button. In an alternative embodiment, a striking mechanism is assembled as an independent unit on a frame plate (57), Figs. 5, 6 (not shown) which carries a battery (58) and a horological movement. Striking is automatically silenced at night by means of a cam (116), Fig. 7 (not shown) which is rotated once every twenty four hours and restrains the hammers.

Abstract: 493,639. Vulcanizing rubber; porous plastic compositions ; moulding rubber compositions. CONSOLIDATED RUBBER MANUFACTURERS, Ltd. May 7, 1937, No. 13117. Convention date, May 8, 1936. [Classes 70 and 87 (ii)] Relief designs are made in the surface of a rubber article, the valleys of the design are filled with a plastic wet paste containing finely divided solid material insoluble in the liquid vehicle, and the article is cured when in contact with the wet paste. The hills of the design also may be coated with the paste. The liquid vehicle may be water. The solid material may be clay, chalk, whiting or infusorial earth. Microporous battery separators may be made by incorporating into the rubber colloidal clays, bentonite, silurian shale, water-soluble soaps or proteins such as casein and subjecting the separators to a submarine cure ; swelling of the rubber is aided by abstraction of water from the paste. As shown, calendered rubber sheeting 2, profiled by a grooved roller 1, is supplied with clay paste 11 passing under an electromagnetically-vibrated doctor blade 9, and rolled up with a fabric liner 6. The roll 16 is heated in water below curing temperature to swell the rubber and then cured by immersion in heated water or saturated steam. The liner 6 may be omitted from the roll 16. To compensate for shrinkage of the calendered sheet the conveyor 3 may comprise two or more belts travelling at successively decreasing speeds, or the calendered sheet may be annealed in hot water or air before application of the paste. Flooring, floor mats, tiling, door mats and panelling made be made.

Abstract: 134,528. R³tgerswerke Akt.-Ges. Oct. 26, 1918, [Convention date]. Tar oils, extracting and purifying.- A substitute for petroleum jelly is obtained by treating finelydivided pitch from tars that contain about 50 per cent or more of aliphatic hydrocarbons with solvents such as benzine, benzene, ethyl alcohol, methyl alcohol, acetone, and ether, alone, or mixed, at a temperature below the softening point of the pitch, separating the solution and distilling off the solvent. The crude product thus obtained may be purified by sulphurous acid, sulphuric acid, alkalies, or other bases, used alone or in succession, and decolorized by filtration through charcoal or other decolorizing agent. The filtration may be fractional so as to obtain products of different quality. Suitable tars specified are low-temperature tars, lignite tars, and tars from gas producers with by-products recovery. The pitch is obtained by heating the tar to 300‹ C. preferably at an absolute pressure of 60 cms.; it melts in 50-60‹ C. In an example, 100 kilos of pitch from a brown coal tar were lixiviated with 3-4 volumes of benzine at 0‹ C.; after decolorization and distillation of the solution, 45 kilos of petroleum substitute remained.
