Title: Information conversion systems utilizing optical memories
IPC: G06V10/88
Filed: 1970-06-22
Abstract: 1319977 Character recognition TOKYO SHIBAURA ELECTRIC Co Ltd 22 June 1970 [20 June 1969 21 Aug 1969 16 Jan 1970(2) 11 June 1970] 30086/70 Heading G2J [Also in Division G4] An optical conversion device converts a digital optical pattern to another digital optical pattern by passage of the light beams forming the input pattern to an optical memory and by combining the emergent beams to form a composite output image. The invention is applied to the reading of an optical memory and to character recognition. Fig.5 shows an optical memory reader in which a digital electrical signal in parallel form and its complement energises a matrix array of eight lamps 40. The pattern of light beams passes through an optical memory consisting groups of 4 x 4 micro-dots recorded on a photographic plate of film 42 as shown in Fig.5. Lens array 42 superimposes the light patterns emerging from the eight groups of micro-images to produce a unique 4 x 4 pattern of dots. Instead of lamp 41, lasers producing coherent beams may be used with a hologram type of optical memory. Fig.11 shows a character recognition device in which the image of a character A (Fig.12) printed on a paper 71, is focused on to a matrix array of holes in a plate 73 the dot image from which is focused on to a similar array of photo-cells in a unit 76. Each photo-cell controls via a threshold device a laser to produce a coherent dot image of the character (Fig.12c) which is focused on to a hologram 77. The emergent beams are combined to produce a 10 x 10 dot image shown in Fig.12d which is focused on to a corresponding array of photocells in a unit 78. Unit 76 produces a coherent but complementary image to that of a channel for focusing on to a complementary hologram 77<SP>1</SP>. The resulting combined image of dots as shown in Fig.12d' is focused on to a similar array of photo-cells in a unit 78<SP>1</SP>. Parallel signals from photo-cells in units 58 and 78<SP>1</SP> are compared in an AND logic arrangement 79 to give an  output signal identifying the character A. It can be seen that the optical patterns of Figs.12d and 12d<SP>1</SP> are similar in only the dot in row 2, column 4. Several output signals identifying the character A can be produced depending on the precise relative position of the input image of A and the holes in plate 73, which output signals the apparatus has to recognize as the character A. The combining of the true and complementary output signals in logic arrangement 79 may alternatively be done optically.

IPC: D02G1/02
Filed: 1965-07-16
Abstract: 1,142,617. Crimping yarns. IMPERIAL CHEMICAL INDUSTRIES Ltd. 21 June, 1966 [16 July, 1965], No. 30270/65. Headings D1F and D1W. A bulked multifilament yarn containing not less than 66% of heterofilaments having an out of phase helical crimp is produced by taking a supply yarn with at least 66% of heterofilaments, inserting a false twist therein, beating sufficiently during the insertion of false twist to retain some twist liveliness allowing the filament in the yarn to separate as a result of the twisting and untwisting, and then subjecting the yarn to a relaxation step possibly with heating to develop the heterofilament crimp. The finished yarn has a twist liveliness of not more than 2.5 and preferably less than 0.8 turns/cm. The yarn preferably has a crimp retraction of at least 15%. The false twist is preferably applied to the yarn during the drawing operation. The insertion of false twist during drawing may be effected by the apparatus of Specification 890,053. Heterofilaments which may be used are those of two polyamide components such as polyhexamethylene adipamide and a copolymer thereof with polyepsilon caprolactum or two polyesters e.g. two polyethylene terephthalates with differing molecular weights. The yarn, in fabric form if desired may be subjected to a hot relaxation process to redevelop the crimp which is pulled out in the winding and other processes.

Title: A method and apparatus for embossing or marking hollow metal bodies
IPC: B44B5/00
Filed: 1959-09-07
Abstract: 903,987. Embossing. DALMINE S.p.A. Sept. 7, 1959 [Sept. 9, 1958], No. 30405/59. Class 83 (4). A method of embossing or marking the surface of hollow bodies is characterized in that a plurality of punches are individually and successively presented for striking in a selected sequence and position relative to a body to be embossed or marked and that immediately prior to making contact with the said body each punch defines a cone of which the vertex lies above the point of impact and on the line of travel of the punch. Apparatus for carrying out the method comprises two frames 1 and 2 pivotal simultaneously about two mutually perpendicular axes BB and AA respectively. A forked arm 10 secured to the frame 1 is oscillated by a roller 11 adjustably eccentrically mounted upon a disc 12 (Fig. 7). The disc is controlled by gear-wheels 30, 32 integral with the disc and a shaft 34 respectively. Rotary movement of the disc imparts an oscillatory movement to the forked arm 10 and the frame 1. Frame 2 is operable in like manner by a forked arm 36 and a roller 38 eccentrically and adjustably mounted on a disc 40. The frame 2 is provided with a further frame 13 movable with the frame 2 but slidable along the axis AA along guides 14, 14<SP>1</SP> by a rack and pinion 15, 16 (Fig. 5). Within the frame 13 is provided a frame 17, the plane of which is at all times parallel to the plane of frame 13, the frame 17 being slidable along the axis BB by rack and pinion 18, 19. The frame 17 carries a plate 20 on which is mounted a set of punches 21. When the axis of a punch passes through a point x, which is the intersection of the diagonals of the frames 1 and 2, the punch is aligned with a hammering member 22 connected to the frame 2. In operation, the blow of the hammering member 22 upon the punch 21 and upon the next following punches when presented to the said member always takes place at the point X of the outer surface of the hollow body or container K and the first impression will be obtained with the punch 21 in a vertical position. The punch is then displaced with its axis in an inclined position and rotated according to a generating line of a cone with its vertex in X to return to a vertical position and the head of the punch is always under the hammering member 22. This is achieved by successive and orthogonal oscillation of the frames 1 and 2.

Title: Improvements in or relating to the preparation of normal barium soap grease compositions
Filed: 1947-11-21
Abstract: Normal barium soap lubricating grease is prepared by saponifying fatty material with not more than the stoichiometric quantity of barium hydroxide in the presence of mineral oil of viscosity gravity constant 0.870 or over, dehydrating the product at temperatures not in excess of the melting point of the soap, cooling the dehydrated product with continuous stirring till below the critical transition temperature range (in which range the grease loses its homogeneous gel-like structure) without reducing the concentration of soap to substantially below 40 per cent, and adding mineral lubricating oil to obtain a grease composition of the desired consistency.  The fatty material may be a fatty acid, such as stearic, palmitic, behenic, oleic or hydroxystearic acid, a mixture of fatty acids or a glyceride.  Where glycerides are employed, however, the glycerine formed during saponification must be substantially removed by steam distillation or by prolonged heating in the dehydration stage.  In an example, stearic acid and a naphthenic mineral lubricating oil of V.G.C. 0.884 are mixed and heated to 210 DEG  F.  Hot aqueous barium hydroxide is added and the mixture maintained at 210 DEG  F. with stirring.  Half an hour after all the water has evaporated the temperature is slowly raised to 310 DEG  F. and held there for 15 minutes.  The mixture is then allowed to cool naturally, with stirring, to 200 DEG  F. and held at 200 DEG  F. for a further 15 minutes. Finally, an additional quantity of the naphthenic oil is stirred in.  Specifications 566,886 and 610,190 are referred to.
