Abstract: 1,158,939. Character recognition. INTERNATIONAL BUSINESS MACHINES CORP. 13 Feb., 1967 [21 Feb., 1966], No. 6711/67. Addition to 1,093,079. Heading G4R. The threshold of a pattern scanner is adjusted in accordance with the result of comparing an analogue representation of a count of pattern elements with an analogue representation of a count of sets of adjacent pattern elements, after attenuating one of the representations. A plurality of vertical scans by a flying-spot scanner 11, 13 of a character produces a waveform which is digitized at 15, 17, 18 using a threshold from a summing amplifier 24 one input of which comes from a generator 10 as in Specification 899,617 and the other input of which is derived as follows. The digitized signals are shifted into a shift register 21, particular patterns of adjacent black bits being recognized by AND gates 26, 27, 28 and counted at 31. The black bits themselves are counted at 33. The two counts are converted to analogue form at 32, 34 and after attenuating the latter at 35 are compared at 36. Depending on which is the greater at the end of the character, a preset counter 40 is incremented or decremented. The count in counter 40 is converted to analogue form at 41 to provide the second input to summing amplifier 24. The shift register 21 feeds character recognition means 22 at the end of the character. Alternatively, a preliminary scan of a line of characters may be used for deriving the lower input to the summing amplifier 24 as above, before a scan for recognition purposes.

Abstract: 549,557. Casting composite articles. SANSOME, R. D. May 27, 1941, Nos. 6761 and 6762. Drawings to Specification. [Class 83 (i)] In making door furniture, locks and other builders' hardware articles by casting a body of metal on to one side of a stainless steel or other covering plate as in Specifications 399,348 and 412,212, adhesion is improved by first coating the plate on the inner side with an adhering layer of metal or alloy having a melting point the same as or lower than that of the plate. The coating may be applied by dipping the plate, or a sheet or strip from which the blank is to be made, into the molten metal after the outer side has been coated with whitening &c. to prevent adhesion and the inner with hydrochloric acid or other flux. The dipping may be repeated in the same or different alloys. If the body metal is a zinc alloy the coating should be zinc or an alloy thereof and if aluminium it should be tin or an alloy thereof, e.g. tin zinc or tin lead. Specification 414,854, [Group XXV], also is referred to.

Abstract: 1455374 Laminates KURARAY CO Ltd 14 Feb 1974 [17 Feb 1973] 6799/74 Heading B5N [Also in Divisions B1, C3 and D1] Laminates are prepared by bonding an artificial leather substrate to a surface of a porous sheet material comprising a polymer, preferably a polyurethane, having in one surface thereof 30 to 10,000 microholes of 0À5 to 100 Á in diameter per sq. cm. and substantially no holes whose diameters fall outside this range, most of the microholes communicating with the internal pores of the sheet material, and in which the said one surface and/or the other surface is (are) smooth or embossed. The artificial leather substrate may be (i) a fibre-mat comprising mainly bundles of fine-denier fibres of synthetic polymer, each fibre in the bundle being less than 0À5 denier in fineness, and/or oriented multihole fibres of synthetic polymer or (2) a sheet material comprising the fibre-mats of (1) and a non- porous or porous polymer comprising an elastomer, the polymer being distributed in the spaces between the fibres in the fibre-mats. In a typical example (11) a porous sheet material having microholes on its surface is buffed on the reverse side and brought into contact with an artificial leather substrate which had been coated with a polyurethane adhesive. The artificial leather substrate was prepared by forming multicorein-a-sheet composite filaments from nylon-6 and polyethylene, the latter constituting the sheath crimping and cutting the filaments to form staple fibres, forming non-woven fabrics from the fibres, impregnating the fabrics with a solution of polyurethane elastomer, coagulating the solution, drying and then treating the so-formed impregnated fabrics with hot toluene to dissolve off the polyethylene. The laminates so-produced may be used in the production of shoes.

The grooves 13 are adapted to receive resilient collars 12 which clip on to the rod, a collar 12 being fitted in each groove associated with a moving spring, whereby movement of the rod is transmitted to the moving springs. A rod 14 passes freely between the bifurcated ends of the springs 31 ... 39 and has channels 15 adapted to receive further collars 12. The rod 14 is fixed to a top plate 16 by two collars 12 and a collar is also provided in each channel associated with a fixed spring, the free ends of the fixed springs being biased towards their respective collars, whereby the spacing between the fixed springs is maintained. In order to retard the movement of certain of the moving springs relatively to other springs, the collars 12 on the rod. 11 may be of three different thicknesses, the width of each of the grooves 13 being approximately equal to the thickness of the thickest collar, whereby those springs operated by the thickest collars will be operated first and the remaining springs will be operated a short time afterwards dependent upon the thickness of their associated collars. In another construction (Fig. 1, not shown), the rod 14 is omitted and the fixed springs have lateral extensions which engage recesses in a buffer block whereby to space their free ends.

[Also in Division F4] A combustion chamber shell for a gas-fired water heater comprises a flat-sided, open-ended metal shell 1 of rectangular horizontal crosssection having secured to each of its two opposed vertical sides a sinuous water-carrying pipe 4, the uppermost branch 6 of which extends around the junction between said side and a first adjoining vertical side at a point near the upper end of the shell and then vertically down the first adjoining side, whilst the lowermost branch 9 extends similarly on to a second adjoining vertical side at a point near the lower end of the shell and vertically up the second adjoining side, being connected through a hole 15 in the upper region of the shell to an internal heat exchanger (not shown) whose finned tubes are connected through further holes 15 by pipe bends 11, a continuous length of pipe thus being formed. In manufacture the pipe formations may be bent to the required shape and then secured to the pre-formed metal shell, or two sinuous formations may each be secured as shown in Fig. 4 to a flat rectangular metal sheet 13 which is punched at 15 and subsequently folded along the lines 16 to form half of the shell, the two halves being then joined together. Alternatively, the two sinuous formations may be suitably secured to a single rectangular sheet of metal which is then bent along the junctions between opposed and adjoining sides and the two edges joined to form the shell.
