[A Specification was laid open to inspection under Sect. 91 of the Acts, May 4, 1934]. [Class 7 (iii)] Light or heavy fuel supplied through a pipe K<2> to a casing J is controlled by a V-shaped hole G in a hollow fuel valve F which is connected by a link E to an air valve D, which is opened by suction against the resistance of a dashpot M. The flow of fuel is assisted by air admitted through a pipe K to the casing, and the fuel and air are delivered through pipes K<1>, K<3> near a weighted flap P which varies the cross section of the air passage. During idling of the engine, the suction above the throttle valve R, transmitted through a duct W, raises the piston M and allows the valve D to open the fuel valve F to a greater extent, and the rate of supply of the fuel during idling may be adjusted by a nut T which varies the position of the casing J relative to the hole G. By cutting off the fuel supply, air may be admitted to the engine cylinders for braking purposes.

Title: Character pattern normalization method and apparatus for optical character recognition system
IPC: G06V10/10
Filed: 1974-07-08
Abstract: 1479134 Character recognition systems RICOH KK 8 July 1974 [9 July 1973 6 Nov 1973] 30084/74 Heading G4R The electrical image of a character to be normalized is stored in main and auxiliary memories. The image in the main memory is examined to derive a value representing one or more spatial parameters of the character (e.g. slant, vertical moment, horizontal moment). The image in the auxiliary memory is then transferred to the main memory, and is subjected during transfer to a normalizing operation dependent on the parameter value. The normalized image now in the main memory is passed to recognition circuitry. The character, which may be printed or handwritten, is scanned and quantized at 10, Fig. 1, to provide signals representing a 2m row x 2n column matrix of national elementary areas of the field. Diagonally adjacent pairs of bits in overlapping pairs of columns are examined in unit 14 (Fig. 4, not shown) and if either bit of a pair is a 1-bit (character portion) the corresponding bit in the corresponding column of the auxiliary memory 18 is set to 1. The 2m Î 2n bit image in shift register memory 18 is therefore a line-thickened version of the scanned character. Alternate row outputs of the thickening unit 14 are passed to the main memory 16 which comprises m n-bit shift registers so stepped that the image stored is a half-sized version of the image in the auxiliary memory. In an alternative arrangement the main and auxiliary memories may be the same size. The output of the main memory passes to a sensing unit 20 (Fig. 7, not shown) which develops a signal representing the value of the slant, and vertical and horizontal moments, of the image. In one arragement the slant is normalized by shifting the row signals in the auxiliary memory 18 by differing amounts according to the slant value, the shift signals being developed by shift circuitry (Figs. 16, 17, not shown) and the slant-normalized image now in memory 18 then being passed to normalization unit 26. In another arrangement, as indicated in Fig. 1, the image in memory 18 is transferred to unit 26 via slant normalization unit 24 (Fig. 10, not shown) which determines from which stage of each row register in the memory the image signals shall be read. Normalization unit 26 selects signals from unit 24 corresponding to m of the 2m rows of the slant-normalized image, according to the vertical moment value, and outputs signals corresponding to an m x 2n matrix containing a vertically compressed slant-normalized and vertically normalized image. These signals are read in to the main memory 16 under the control of clock pulses developed by unit 28 (Fig. 13, not shown) in accordance with the horizontal moment value such that n of the 2n columns of the m x 2n matrix are stored to provide horizontal normalization and compression. The m x n bit image in the memory 16 is thus fully normalized and may be passed to unit 22 for recognition.
