Title: Improvements in or relating to Character Recognition Systems
Inventor: WOOLLONS DAVID JOHN
IPC: G06V30/168
Filed: 1967-02-13
Abstract: 1,153,703. Character recognition. MULLARD Ltd. 1 March, 1968 [13 Feb., 1967], No. 6698/67. Heading G4R. In character thinning apparatus for use in recognizing a character digitized as a matrix, an operator is applied to each point of the character in turn by a "scanning motion" to remove parts of the character, the operator being a matrix and the "scanning motion" involving applying the operator in each of the orientations in which the operator matrix points register with the character matrix points. The operator matrix is of the form being effectively scanned along successive rows (or columns) of the character matrix in turn, so that point 5 registers with each character matrix point in turn, this being done with the above orientation of the operator matrix (assuming horizontal character matrix rows) and in orientations 90, 180 and 270 degrees rotated. In each ease, a black (i.e. character) point of the character matrix at position 5 is deleted if only one or less of the points at positions 1-3 are black in conjunction with four or more of the points at positions 4-9 being black. The above scheme is implemented by recirculating the (serialized) character matrix in a shift register, each orientation of the operator being implemented as a logic unit fed from stages of the register and controlling a register position via delay. Recirculation continues until no further changes occur. Each logic unit is disabled when a row of the operator matrix is split between rows of the character matrix, under control of a shift count, or a second shift register having "ones" in positions corresponding to gaps provided in the first shift register. As a modification a matrix store may be used for holding the digitized character, the character as modified being inserted into another matrix store, or via a delay or another store back into the same matrix store. Before the above operations, the character signals (from a flying-spot scanner) are subjected to noise reduction as in Specifications 1,106,974 and 1,106,975 which are referred to.

Abstract: 253,481. Mattos, S. M. M. de. June 9, 1925, [Convention date]. Self-driving machines.-A self-driving apparatus which performs external work and also produces a continuous supply of liquid air comprises a chamber A for compressed air, a turbine C driven by the compressed air the exhaust passing through a rotating wheel F and back to the air chamber A. The wheel is rotated with a velocity substantially equal to the molecular velocity of air and acts to produce a vacuum in boxes G, H which communicate with chamber A and the atmosphere. The action of the apparatus is stated to be continuous, and to continuously liquefy the air in chamber A, so that not only can liquid air be drawn off at a tap but also the energy of the compressed air may be utilized for driving a turbine L or a piston engine which can thus perform external work. The turbine L is arranged so that it will run in either direction.

Title: Improvements in or relating to variable capacity electric condensers
IPC: H01G5/12
Filed: 1925-03-14
Abstract: 248,928. Igranic Electric Co., Ltd., and Griffiths, F. R. March 14, 1925. Condenser of the variable type have the ratio of the rate of capacity variation to the rate of movement of the capacity adjusting element greatest at some point between the maximum and minimum capacity setting, the ratiu diminishing as the setting approaches the maximum or minimum. The fixed vane 1 is formed as a semi-cylindrical shell coaxial with which is a movable vane 2 formed as a part-cylindrical shell and rotatable about the common axis of the two shells. The vane 2, as shown developed in Fig. 4, is a parallelogram, but may be a rectangle or other quadrilateral, and it can be seen that the rate of capacity variation for a given rotation of the vane is greatest midway between the maximum and minimum settings and decreases towards zero as the setting approaches the maximum or minimum. The fixed vane is secured in ebonite end-pieces 3, 4 by lugs 6 of which there are three at each end and which are passed through slots in, and bent over, the end-pieces. One lug 6, Fig. 5, 's made longer than the others and bent outwardly to serve as a terminal lug for the fixed vane and the latter is sunk in recesses 7 in the end-pieces. The vane 2 is mounted on the shaft 5 by means of bossed holes 9 in lugs 8, the shaft being passed through the holes and secured to the vane by a screw screwing into a hole in the boss. The bearings for the shaft 5 are constituted by threaded tubes 10, 11 having secuxed near one end thereof metal discs 12, the tubes being passed through the end-pieces until the discs 12 abut them and then secured by nuts 13. An ebonite cover 16 encloses the vanes and is secured by discs 17, 18 and nuts, the disc 17 being secured by a nut 19 which also locates a spring clip terminal 20 for the moving vane.
