Filed: 1975-07-07
Abstract: 1496245 Noughts and crosses B J BARISH 7 July 1975 28551/75 Heading A6H [Also in Divisions B2 G5 and H1] A switching device (see Division H1) based on the principle of the "magic", or self-erasing, slate is adapted to provide an electronic noughts and crosses game. A base 308 in the form of a printed-circuit board is divided into nine boxes A to I each having a central conductive element 310x and a radially-spaced element 310o therein with respective leads 311x, 311o. Overlying this board 308 is a flexible plastics sheet 316 having a conductive metal layer 318 in turn coated with a wax layer 314. The whole is covered by an opaque flexible plastics sheet 320 marked with the conventional lines 321 and 323 and also having X and O indications, 325x and 325o respectively as a guide for marking with a stylus whereby the conductive layer 318 is pressed into contact with an element 310x or 310o, the layer 314 being pressure-flowable and also tacky to maintain the electrical contact after the stylus has been removed. A circuit (Figure 19, not shown) is described which provides an indication when three elements 310x in any horizontal row, vertical column or diagonal are all connected to layer 318; it also gives an indication in similar circumstances with respect to elements 310o. The circuit also provides an indication if both elements 310x and 310o in any one box are actuated. Hence, besides indicating an "X" win or an "O" win, the circuit shows if a player places his mark in a box previously marked by the other player, and therefore loses. Thus an element of memory, not present in conventional sessions of the game, is introduced. After a game has been completed it is only necessary to separate the flexible sheet 316 with its conductive layer 318 from the board 308 to clear the device in readiness for another game.

Abstract: 663,457. Photographic plates. GENERAL ANILINE & FILM CORPORATION. Nov. 8, 1949 [Dec. 16, 1948], No. 28615/49. Drawings to Specification. Class 98 (ii). Hardened gelatino silver halide emulsion layers having no after-hardening tendency and which swell uniformly , in a direction perpendicular to their support when brought into contact with processing solutions are made by incorporating 2,4-dihydroxybenzaldehyde with or without a polyhydroxybenzene such as resorcinol, phloroglucinol, methylphloroglucinol, pyrogallol or 1,2,4 - trihydroxybenzene, or mixtures thereof, into the emulsion; coating, using a support such as cellulose-acetate, - formate, -propionate, -butyrate, -acetate-propionate, -acetate-butyrate or -nitrate, polyvinyl chloride or copolymers of this with vinyl acetate or vinylidene chloride; and providing a low molecular weight organic hardening agent such as formaldehyde, paraformaldehyde, acetaldehyde, glyoxal, pyruvic aldehyde, nitromalonic aldehyde, mucochloric acid, or trimethylolmelamine in a further colloid layer or in the support itself so that this hardening agent may diffuse into the gelatino silver halide layer and effect or complete the hardening process. Trimethylolmelamine, itself film-forming, may be applied in aqueous solution without a separate colloid. The process avoids irregularities, in photographic quality, of the resulting hardened layers, which may result from adding all the hardeners to the emulsion melt in processes as of Specification 632,763. In Example I, formaldehyde is applied in gelatine solution, so as to constitute an overcoat layer lying upon an emulsion layer containing 2,4-dihydroxybenzaldehyde and resorcinol. Examples II and III apply, similarly, gelatine solutions of glyoxal and other aldehydes. All the examples show data comparing the emulsion layers before and after application of the additional aldehydes. Specification 604,378 also is referred to. The Specification as open to inspection under Sect. 91 comprises also the application of formaldehyde and similar hardening agents in solution or gaseous form, without a colloid, to emulsion layers of the type indicated above. This subject-matter does not appear in the Specification as accepted.
