Patent GB-1337368-A (GB)
Title: Character recognition device
IPC: G06V10/24
Filed: 1972-02-24
Abstract: 1337368 Character recognition systems INTERNATIONAL STANDARD ELECTRIC CORP 24 Feb 1972 [25 Feb 1971] 8548/72 Heading G4R A character recognition system includes a circuit providing a "decision" pulse which is applied to the recognition circuitry to maintain the correct timing even if the character is too badly mutilated to be recognized. As described OCR-A characters are scanned, the serial signals from the scanner passing to a shift register of capacity sufficient to hold all the data from the character field. Various of the cells are connected to gating logic, Fig. 4 (not shown), so that, in effect, a number of windows are swept over the character as the signals step through the register. When the "Black" character signals occupy at least some of the cells in a preset group of windows a "pattern" pulse is generated on a lead corresponding to the particular character being scanned. The pattern pulse leads are connected to respective counters forming part of the recognition circuitry, the counters being reset by a signal from the circuitry after a decision pulse has occurred. In order to make small gaps in the character insignificant only some of the cells of a window need be black to represent a character portion. For example, in the case of a vertical window 7 cells high and 1 cell wide a vertical portion of the character is considered to be present if 2 of the middle 3 cells are black and 1 of both the outer pairs of cells are black. The decision pulses are generated by a circuit, Fig. 5 (not shown), which receives as inputs all the pattern pulses and also black pulses from a selected one of the cells of the register. When a pattern pulse occurs a decision pulse is generated at a preset time thereafter, at which time the following character is being read in to the register. Receipt of a pattern pulse prevents the circuit responding to any subsequent pattern pulse arriving during a fixed period thereafter long enough to ensure that all the pattern pulses relating to the character being scanned have been generated. The circuit also generates a decision pulse when the start of the character is detected and when the inter-character space is detected. Thus a decision pulse is provided even if the character is too distorted to be recognized and no pattern pulses are generated, or if adjacent characters touch. Generation of any one of these decision pulses prevents the generation of either of the others.

Title: Combined viscosity pump and electric motor
IPC: F04D5/00
Filed: 1971-04-03
Abstract: 1373955 Viscosity pumps W A BULLDUGH 28 March 1972 [3 April 1971] 8594/71 Heading F I C A viscosity pump comprises a radial gap defined.between the rotor, stator and end-plates of a electric motor, inlet and outlet ports communicating with the gap, and a barrier means between the inlet and outlet ports. A shaded-pole rotor 1, Figs. 1 and 2, is journalled on a stationary shaft 13 carried by end plates 10. Fluid to be pumped is suppled via an inlet port 7 to the peripheral gap 6 between the rotor 1 and the stator 2, and is discharged via an outlet port 8, sealing between the ports 7, 8 being provided by a tongue 9 disposed axially or askew and wiping against the rotor. The rotor may instead be fixed to a shaft journalled in in the end-plates 10, and the shaft may then extend through one or both end-plates to drive an external load. There may be three or more pairs of ports 7, 8 and associated tongues, Fig. 4, so that the rotor is self-aligned hydrodynamically. Recesses 15 in the stator are shaped so that each gap 6 decreases in height towards its outlet port 8. A secondary pumping gap 24 in series with. the main pumping gap 6 may be afforded between the stationary shaft 13 and the rotor interior 25. The tongue may be flexible or may be pressed into contact with the rotor by a spring or by hydraulic pressure supplied from the outlet port 8 or another source. The tongue 9 may stand clear of the rotor or may have a hydrodynamic tilt, or may be replaced by a revolving cylinder bearing against the rotor. The tongue 9 may be omitted, the rotor axis then being eccentric to the stator so that the rotor bears against the stator at a point between the ports 7, 8. The ports 7, 8 may be elongated axially, staggered towards opposite ends of the stator or located in opposite end-plates 10, and the gap 6 may in the latter case comprise a helical groove formed in the stator or the rotor. In the pump shown in Fig. 6, the outer member 2 forms a rotor carrying fan blades 17 and the inner member 1 forms a stator carrying the tongue 9 and formed with ports 7, 8 which extend into a stationary shaft 16. The pump may be submersible.

Abstract: 461,722. Casting reinforced-concrete masts. GHIRA, A., and GHIRA, G., (trading as GHIRA, SOC. DI COSTRUZIONI, INGG. A. & G.). March 23, 1936, No. 8607. Convention date, March 23, 1935. [Classes 20 (i), 20 (ii), and 20 (iv)] A method of making reinforced-concrete lattice-work' masts consists in using divided mould boxes for the uprights A and diagonals C, Fig. 1, parts of these mould boxes being used as scaffolding for carrying out the work and the other parts being attached thereto prior to the casting operation. Horizontal stays, when such are provided, are similarly constructed. In the construction shown, the uprights of the scaffolding are of angle section and consist of a number of sections joined end to end by hingelike joints 1, Fig. 3. The diagonals consist of pairs of plates 10 which are supported by channel-members a connected to the uprights. Prior to the casting operation, angle-plates 6 are connected to the uprights to form mould boxes, the connection being effected by pins 7 which pass through holes 8 and by means of wires threaded through holes 9<1> in their abutting flanges. The mould boxes for the diagonals are completed by upper and lower plates which are connected by wires to the plates 10. The horizontal scaffold members b may be of the same construction as the diagonals or, as shown, these members serve only to support a staging 3. The various mould-box elements are preferably formed in sections having bevelled ends. To facilitate the removal of the lowermost mould box of each upright, it is made in two sections, the lower one of which can be slidden upwards. The reinforcement for the mast consists of vertical bars 4, Fig. 5, and encircling bars 20, the bars being held in position by metal strips 19 having pointed ends. The Specification as open to inspection under Sect. 91 describes also a method of constructing a simple mast comprising a single upright, the scaffolding comprising three uprights, one only of which forms a part of the mould box for the mast. A bracket mould 16, Fig. 10 (Cancelled), and a device 17, Fig. 11 (Cancelled), for supporting a climbing bar during the casting operation are also described. This subjectmatter does not appear in the Specification as accepted.

Filed: 1920-03-24
Abstract: 162,503. Spivey, F. March 24, 1920. Mines, marine.-To prevent a moored submarine mine from being swept aside by a paravane or like device, the mine A is provided with quadrant vanes B hinged at C and normally held folded against the lower part of the mine, as shown in Fig. 1, by a ring F which fits over spring tongues D at the ends of the vanes. The ring F is held up by a spring J abutting against a stop L fixed to the mooring cable K; and a weight N slidable over the mooring- cable is hung from the ring F by a pair of ropes M to which is fastened a transverse bar P carrying a pair of serrated jaws R and slidable over the mooring-cable. When a sweeping- cable G encounters the cable M, the latter is bent, as shown in Fig. 3, the sweeping-cable is guided into the. jaws R and pulls the ring F down against its spring J; whereupon the vanes D are opened out by springs E and by the water Sowing past them until stopped by chains H. The increased drag due to the vanes causes the mine to strike and explode against the side of the ship from which the paravane is towed.
