Title: Improvements in and relating to padlocks
IPC: E05B67/22
Filed: 1927-04-14
Abstract: 276,593. Ralls, J. C. April 14, 1927. Padlocks.-In a padlock having pivoted plates c each operable in both directions by a key passing through an aperture d therein as described in Specifications 27133/96, 11988/10, and 270,094, the plates are spring-pressed towards the locking position, one end of each spring m being secured in a slot in the corresponding plate, and the other end of the spring bearing against the interior of the casing a. This construction allows the use of only two plates or of a single plate. Movement of the plates may be limited by protuberances o, which may also have apertures adapted to receive rivets holding the cover plate (not show.n) in place. The plates co-operate with a projection j on the sliding bolt f and are operated by a key inserted in a keyhole d to bring slots k in the plates into register, so that the bolt f may be projected to the unlocked position, the projection j entering the registered slots.

Title: Improvements in electrode systems with unsymmetrical conductivity
IPC: H01L21/103
Filed: 1936-04-07
Abstract: 450,393. Asymmetrically conducting resistances. NAAMLOOZE VENNOOTSCHAP PHILIPS' GLOEILAMPENFABRIEKEN, Emmasingel, Eindhoven, Holland. April 7, 1936, No. 10276. Convention date, June 1, 1935. Drawings to Specification. [Class 37] [See also Group XL] Relates to an electrode system with unsymmetrical conductivity for a dry rectifier comprising between the electrodes a separate insulating coating which is arranged or formed independently of the electrode material and consists of a material applied in the liquid or dissolved state or which softens at an increased temperature of say 100‹ to 200‹ C. e.g. artificial resin or polystyrene. According to the invention, solid insulating material, such as powdered mica, quartz powder or aluminium oxide powder, is added to the insulating material. Further examples of an insulating coating according to the invention are paper impregnated with molten sulphur or shellac mixed with mica powder. According to one constructional form of the invention, an amorphous selenium layer is applied in the liquid state on to a brass support and after this layer has been smoothed the electrode is dipped in a solution of polystyrene in a rapidly evaporating solvent, such as benzene, containing finely divided mica powder. On withdrawal of the electrode, the solvent evaporates immediately whilst the insulating coating remains behind and adheres to the electrode which is then introduced into a furnace and kept for a comparatively long time at a temperature of about 200‹ C. Alternatively, the insulating coating may be applied after heating the selenium but in this case it is desirable to repeat the heating operation at about 200‹ C. Finally, a counter electrode of Wood's metal is applied to the insulating coating. The construction of the electrode system may also be carried out in the reverse order. Thus, in manufacturing a photo-electric cell, the insulating coating of polystyrene containing mica may be applied to a counter electrode consisting of silver precipitated from the vapour phase on a glass support whereupon the semi-conductive electrode together with the support is attached to said coating.

Title: Improvements in or relating to marking machines
IPC: A43D95/14
Filed: 1951-05-04
Abstract: 713,755. Printing-machines. BRITISH UNITED SHOE MACHINERY CO., Ltd., BAGSHAW, C. M., and LUTYENS, J. L. May 5, 1952 [May 4, 1951; Oct. 6, 1951], Nos. 10465/51 and 23309/51. Class 100 (2) In a machine for marking blank pieces of material with a design, especially boot and shoe blanks, a platen 10 is supported by two pairs of pivotally mounted links 12 and 14 for movement parallel to two tables 6 and 8, and is loaded by a substantially vertically moving weight. The table 8 supports the blanks to be marked, while the table 6 carries a marking substance; e.g. ink spread directly thereon, on a pad, or on a ribbon. As shown, a member 22, clamped to a shaft 16 pivotally supporting the links 122, has a lever 24 carrying a detachable weight 26 pivoted on its lower end. The lever 24 is pivoted to a link 28 pivoted to a fixed member 30. In operation, the platen is moved manually by a handle 20 so as to mark a blank on the table 8, thus raising the weight 26 in a mainly vertical path, whereupon the handle is released to cause the platen under the influence of the weight 26 which swings downwardly, to contact the marking substance on the table 6. In a modification, movement of the platen towards the table carrying the blank causes a weight, suspended on one end of a chain secured at its other end to a pulley, to be raised. When the handle is released, the weight drops, thus causing rotation of the pulley and through a second chain pivotal movement of one pair of 'inks supporting the platen, such that the platen contacts the table carrying the marking substance. Alternatively, the machines may be operated by a treadle connected either directly to the platen or to one of the shafts supporting the platen.
