Abstract: 710,754. Book-keeping; clamping devices. WILSON, R. A. Oct. 10, 1950. No. 24686/50. Classes 16 and 146(1) Apparatus for holding documents such as account sheets, carbon papers and the like in superimposed relationship on a base board by means of clamping or holding means mounted on the base board, the clamping means comprise at least one strip-like element having an outwardly directed foot portion, at least one striplike element disposed in parallel relation to the first element and arranged to cooperate with the foot portion to form a clamp, the 'foot portion in turn being arranged to co-operate with the base board or a corresponding foot portion on a further strip-like element to form an underlying clamp and means associated with each strip-like element for moving it towards and away from the base board into and out of operative position, the arrangement being such that when an element having a foot portion is moved away from the base board, the element or elements cooperating therewith are retained in operative relation so that any sheet or sheets held thereby will not necessarily be released. On a base board 1 are mounted brackets 2, 3 supporting a spindle 4 on which are pivotally mounted five clamp elements 6, 7, 8, 9 and 10 each comprising elongated metal strips of L-shape in cross- .section disposed one above the other, one limb of each extending towards the base board 1. The elements 8, 10 are provided with outwardly directed foot portions 8b, lOb, the elements 6, 7 clamping papers against the foot portion 8b, the elements 8, 9 clamping against the foot portion 10b and the element 10 clamping against the base board 1. The upper limb of each element has depending side lugs 11-15 and 16-20. which are apertured to receive the spindle 4. and rearwardly extending operating arms 21-25 respectively which are staggered with respect to each other to allow separate operation of each. Since the upper limbs of the elements 6-10 are disposed one above the other, operation of the arm of any of the elements 7-10 will raise the elements lying thereover, but when the elements 8 and 10 are raised, papers clamped to the foot portions 8b, 10b will not be released. Each clamp is spring-pressed to operative position by springs 27-31 mounted on the spindle 4 and pressing against the respective operating arms 21-25. A back stop 5 for the lowermost papers is secured to the base board 1 and the outer edges of the foot portions 8b, 10b, are cut away at 27a to facilitate insertion of papers thereover.

Abstract: 1,109,604. Electric selective signalling. ELLIOTT BROS. (LONDON) Ltd. 10 June, 1965 [20 June, 1964], No. 25606/64. Heading G4H. In a display system data stored in a core or drum store is displayed in mosaic form on cathode-ray tubes. The tubes denote portions of track and the characters displayed the identity of vehicles on it. The character codes having been entered via a selector switch into a core store, data relating to mosaic spot position 1 on each tube is read out serially and fed via AND gates to bi-stable stores and from thence to the display tubes. The tubes have a common time base. The data is passed back to the store and data relating to position 2 is then read out. To show movement of vehicles from one track section to another the data returned to the store, instead of being written into the core from which it was read, is passed to another core, if necessary via a spare core, which represents the same mosaic spot but on a different tube which represents the new section. In one embodiment such a transfer occurs under the control of an arrangement of gates, but in the second embodiment each serial group of data representing a spot position is read out twice, first for display and second for transfer of bits.
