Title: Method and apparatus for calibrating mechanical visual part manipulation system
IPC: G05B19/4093
Filed: 1976-10-20
Abstract: 1518244 Workpiece manipulator BENDIX CORP 20 Oct 1976 [28 Nov 1975] 43555/76 Heading G3N A robot arm 26 has sensors which generate signals indicating the position of a work holder 28 in a first co-ordinate system. A TV system 22, 20 generates signals, representing the position of a part 10, in a second co-ordinate system. A digital computer 24 receives both first and second co-ordinate system signals and converts the second to the first. The co-ordinate conversion is effected by finding the angle of rotation between the two systems and the distance between their origins by observing a target moved by the work-holder in the two systems. It also calculates a length scaling factor representing the ratio between an observed distance in the different systems. The digital computer can be replaced by hardwired circuits or an analog computer.

Filed: 1977-10-24
Abstract: 1534129 Error detection INTERNATIONAL BUSINESS MACHINES CORP 24 Oct 1977 [20 Dec 1976] 44201/77 Heading G4A In the transfer of a multi-byte word, e.g. into and out of a store, an input interface inverts, at least one bit, e.g. the parity bit, of at least one byte but not all bytes, e.g. byte 1, and an output interface reinverts the same bit(s) before performing a parity check. When writing into the store, byte parity generator-checkers 16, 21, 22 generate respective parity bits on lines 20, 23, 24. The parity bit for byte 1 is inverted by an AND-inverter 17. On read-out from the store the parity bit of byte 1 is reinverted by an AND-inverter 18, and the parity checks are performed by generator-checkers 16, 21, 22. This arrangement enables error control logic 11 to detect stuck at all 1's or all 0's conditions arising from a word line failure in the store, irrespective of the number of bits in each byte and whether the parity constraint is even or odd.

Abstract: 946,536. Spinning. L. C. DAMMAN. Nov. 27, 1962 [Nov. 28, 1961], No. 44776/62. Heading D1F. An apparatus for removing residues of textile yarns wound on spools, cops, cones, tubes or bobbins, is characterized in that supports 36 Fig. 4 are fixed to the inner wall of a rotating drum, and are each provided with a coil spring 41 disposed in a circular arc so that the turns thereof are in contact at the inside of the curve and fall out on the outside, the spring being supported so that it is not deformed by the support on which it is mounted. Each support 36 comprises a flat plate having a V-shaped groove on one edge with two pegs 42, 43 to hold the spring, and a rib of flexible material along another edge 38. Bobbins &c. are fed into the drum which may be of polygonal or circular cross-section, through an opening 14 in the end 13 and the drum rotates the bobbins strike the springs and some of the yarns are gripped between the turns of a spring. Lengths of yarn thus unwound from the bobbins are wound around an inner drum 24 which rotates at a faster rate than the outer drum so that the yarns are extracted from the grip of the springs. The bobbins gradually moved down the inclined outer drum and are deflected by a plate 47 through an opening 46. The outer drum is rotated by a motor 19 through one of the rollers 11 which support a circular rail 12 connected to the end 13 of the drum. The inner drum is rotated either from a shaft 15 of the outer drum through pulley system 6, 28, 29, 20 or direct from a separate motor. The yarn is removed from the inner drum by a cutter blade either entering a longitudinal groove, or being pressed against a rib 32<1>. Alternatively the yarn slides off if the inner drum is tapered. A flexible sponge like material preferably covers the inside of the outer drum.

Abstract: 963,826. Polypropylene films. IMPERIAL CHEMICAL INDUSTRIES Ltd. Dec. 17, 1962 [Dec. 22, 1961; March 9, 1962], Nos. 46037/61 and 9125/62. Heading B5B. A polypropylene film biaxially oriented by a tubular process and collapsed or slit is held at its edges to restrain transverse shrinkage and subjected to a heat treatment under conditions of time and temperature such that the film readjusts itself (with little or no overall shrinkage) sufficiently to substantially reduce sag and wrinkles but not sufficiently severe to cause substantial heat setting of the film or result in shrinkage whereby its desired shrinkage properties are lost at the temperature at which shrink packaging is desired. The temperature of heat treatment is preferably not more than 100‹ C., and is desirably not more than 20‹ C. below the temperature at which shrink packaging is desired. Overall shrinkage during heat treatment is preferably not more than 5.0% in the transverse direction and not more than 2% in the longitudinal direction. In a preferred method, heat treatment is effected while the film is continuously moved forward in a substantially parallel or slightly diverging stenter. Alternatively, rollers having means to engage the edges of the film and permit some shrinkage over the rollers may be used. Film subjected to the heat-treatment may be made by process in which a tube of unoriented polypropylene has its temperature adjusted to a temperature below the melting point at which it can be uniformly expanded to biaxially orient it and is expanded by internal gaseous pressure (with or without an additional stretch in the longitudinal direction) and is hauled off as a biaxially oriented polypropylene film, and in which the film has been cooled by circumferentially, uniformly applied draughts of air at least over the second half of its zone of expansion and under conditions of temperature of the tube before stretching it and internal gaseous pressure such that the hoop stress in the polypropylene tube just before it commences to stretch is at least 16.5 p.s.i., preferably at least 20 p.s.i. Film so made and treated is transparent, shrinkable, substantially sag-free and has an "area" shrinkage (defined as the sum of the longitudinal and transverse shrinkages) at 120‹ C. of at least 20% combined with a tensile break strength of at least 25,000 p.s.i. in all directions in its plane and/or a haze of less than 10%, and preferably has a transverse shrinkage above 18% and a thickness in the range 0.0004 to 0.0016 inch.

Abstract: 921,007. Fertilizers. J. BINNS. Dec. 28, 1961, No. 46525/61. Class 111. [Also in Croup XXX] In fermenting domestic refuse to compost after addition of water, as described in Specifications 919,955 and 921,006, the refuse is fermented in one or more stationary fermentation chambers in which the material is intermittently stirred while being intermittently conveyed along the chamber. In a preferred form of the invention, refuse on a collection pit 1 is sprayed with water (e.g. 30-45% by weight) from a pipe 2, and transferred via conveyer 3 and cutting mill 4 to a horizontal cylindrical fermentation chamber 5. This chamber has a solid wall 6 at its inlet end, a perforated or mesh wall 7 at its outlet end and is conveniently about 12 feet in diameter. Extending co-axially through the chamber is a rotatable tubular shaft 8 which carries on radial supports a series of helically inclined blades 9, which on rotation of the shaft, move the fermenting mass along the chamber and also stir the material. The blades have yieldable tips 10, e.g. of rubber. Compressed air is supplied intermittently through jets 11 to maintain the temperature of the mass at 150‹F. for 3 days. After this time, the fermented material travels from the end of the chamber, on elevator 14 via magnetic ferrous metal separators 15 and 16 and non-ferrous metal extractor 17, to a pulverising mill 18, from which the finely-ground fully-fermented material is removed by conveyer 19.
