Title: Improvements in tufting machine operating methods
Inventor: ELLISON RONALD
IPC: D05C15/32
Filed: 1966-05-13
Abstract: In a method of producing a pattern of long and short loops by a tufting machine which comprises a plurality of needles, brake mechanisms for the yarns, and a constant-speed yarn-feed roller having a surface over which a braked yarn may slip, a long loop is produced without braking a yarn, and a short loop is produced by applying the brake to the yarn when the looper engages the yarn after the needle commences to rise, and by removing the brake when the looper disengages from the loop and before the needle is fully retracted from the base fabric.  It is stated that a small constant part of each preceding loop is withdrawn, and that each needle stroke determines its own loop length.

Title: Improvements in or relating to animal feed and process of preparing same
IPC: A23K20/195
Filed: 1950-08-30
Abstract: To an animal feed is added the liquor (or the dried solids of the liquor) resulting from the aerobic fermentation with Streptomyces aureofaciens of a nutrient medium, exemplified by a medium containing 1 per cent corn steep liquor, 1 per cent sucrose, 0.2 per cent (NH4)2HPO4, 0.2 per cent K2HPO4, 0.025 per cent MgSO4.7H2O, 0.1 per cent CaCO3.  Before incorporation in the feed, aureomycin may be removed from the liquor, e.g. from a liquor which has fermented for 24-72 hours at pH 5-8 at 28 DEG  C., the aureomycin is removed by increasing the pH to 8.5 or more and separating the precipitate which forms.  S. aureofaciens produces in the liquor aureomycin, vitamin B12, another vitamin designated vitamin B12b, and apparently still another growth-stimulating factor, and there are described experiments involving the feeding of chicks to demonstrate that only part of the growth response on diets including the liquor is due to vitamin B12.ALSO:An animal feed contains the growth-promoting factors produced by aerobic fermentation of a nutrient medium with Streptomyces aureofaciens.  The value of vegetable protein in particular, in feeds containing such protein, is enhanced by supplementing the feeds with liquor resulting from the fermentation, or the dried residue of this liquor; aureomycin may previously have been extracted from the liquor.  Experiments involving the feeding of chicks and of pigs on basal diets supplemented by the liquor are described.ALSO:To an animal feed is added the liquor (or the dried solids of the liquor) resulting from the aerobic fermentation with Streptomyces aureofaciens of a nutrient medium comprising a source of assimilable carbon, a source of nitrogen, e.g. amino acids, casein, meat extract, soybean meal, corn steep liquor, urea, nitrates, and inorganic salts including phosphates, calcium, magnesium, potassium and iron, a typical medium containing 1 per cent corn steep liquor, 1 per cent sucrose, 0.2 per cent (NH4)2HPO4, 0.2 per cent K2HPO4, 0.025 per cent MgSO47H2O, 0.1 per cent CaCO3.

Title: Fishnets formed of synthetic resin strands and strands therefor
IPC: A01K75/00
Filed: 1950-09-01
Abstract: A continuous filamentary knot-retentive strand for use in the manufacture of knotted fishnets has a filamentary core, preferably a multi-filament core, formed of a synthetic linear high-polymer resin, e.g. a polyamide, polyester, polyacrylate or polyacrylonitrile, which has been stretched and set to make it substantially retraction-proof when wetted at atmospheric temperature, and a water-insoluble synthetic resinous coating which, when set, has a greater compressibility than the stretched and set core and is of such thickness that the strands are caused to imbed themselves partially into one another in knotted together portions.  The strand is produced by applying the coating in an aqueous medium to the filamentary core, stretching the core and subjecting it while stretched and while coated with the liquid composition to heat above the boiling-point of the aqueous medium but insufficient to soften the core, for a length of time sufficient to set the coating and the core.  Specified coating compositions for application to a 6-6 nylon filamentary core are (1) an aqueous emulsion of polystyrene containing diethyl phthalate; (2) an aqueous suspension of 8-8 nylon containing ethyl alcohol; (3) an aqueous polyvinyl butyral emulsion containing dispersed silica and (4) an aqueous dispersion of 8-8 nylon, containing ethyl alcohol and dibutyl-, diethyl- or dimethylphthalate.ALSO:A continuous filamentary knot-retentive strand for use in the manufacture of knotted fishnets has a filamentary core, preferably a multi-filament core, formed of a synthetic linear high-polymer resin, e.g. a polyamide, polyester, polyacrylate or polyacrylonitrile, which has been stretched and set to make it substantially retraction-proof when wetted at atmospheric temperature, and a water-insoluble synthetic resinous coating which, when set, has a greater compressibility than the stretched and set core.

Title: A numerical control system for machines
IPC: G05B19/27
Filed: 1965-05-21
Abstract: 1,099,315. Programmed control of machines. LICENTIA PATENT-VERWALTUNGSG. m. b. H. May 21, 1965 [May 25, 1964], No.21644/65. Heading G3N. In a programmed numerical control system for machines, wherein a tool or workpiece is always moved in one direction while the tool is engaged, the reading from the program carrier of a word containing path or operational information is only effected after the termination of the executing of the previous instruction, the path instructions being stored in an input shift register and processed in an arithmetic unit with correction values, whilst operational instructions pass through the shift register and the arithmetic unit directly to stores that control associated control devices. As shown, a word recorded on a punched tape is read by a reader L5 and stored in a store PS. The word address is transferred to a store WAS through a decoding matrix EM while the word is fed to a shift register ES through a changeover device U. When the word relates to a distance instruction it is fed through line A where it is summated in an arithmetic unit RW with an offset correction from a selector switch Nx, Ny, Nz. The corrected position value is returned through a store RS and the device U to the shift register ES which acts as a store ZS. The corrected position value is then summated in unit RW with a tool offset value from a selector switch FR and returned to the store ZS through the device U. The final corrected position value is summated with an actual position value from angle decoders WKx, WKy, WKz to derive a control deviation signal which is fed to a sign store R comprising a self-holding relay. A feedmotor VM then operates in a direction determined by the contents of a store U under control of the control deviation held in a store V. Speed reduction for small deviations is effected through a matrix VAM, which at a small value of the control deviation signal, causes a switch over of motor VM to a slow zeroing speed. An operational address introduced into the word store WAS causes the associated information to be fed through the arithmetic unit RW directly to the spindle speed store U, the feedrate store V and auxiliary drive store H. Manual control is directly effected by selector switches HH, HR, HU, HV.

Title: Mounting filamentary materials for tensile testing
Inventor: BAKER BERNARD STUART
IPC: G01N3/08
Filed: 1967-05-10
Abstract: 1,215,601. Mounting filaments on tapes. COURTAULDS Ltd. 9 May, 1968 [10 May, 1967], No. 21687/67. Heading B8C. A method of mounting samples of filamentary material for tensile testing comprises engaging the ends of the length to be tested between two sheets, at least one of which is of deformable material, and at least one of which has an adhesive layer. During testing, the jaws of the testing machine grip the material enclosing the sample ends instead of the sample itself. In the embodiment described, the method involves fixing samples 4, Fig. 1, across successive apertures in a tape 1 by tapes 3. The tape 1 is fed from a reel 74 to a roller 71, Fig. 2, and two parallel tapes 3 pass from a reel 76 over a grooved roller 79 and rollers 54. The tapes are joined between the rollers 71 and 54 after a filament 4 has been manually placed on the tape 1. Either the tapes 3, or the side strips of the tape 1, or both, may be adhesive, and are preferably made of plastics, e.g. polyvinyl chloride or polyethylene. Holes 6 of tape 1 are engaged by pegs 72 on the roller 71, which is driven intermittently to push the joined tapes under two spring-urged rollers 41 lying upon the tapes 3 and then past a manually operated guillotine 89. An electric motor 16 rotates a cam-shaft 24 to rock a lever 45, so raising and lowering a bar 51 and an arm 58. The bar 51 accommodates the rollers 54. The arm 58 is pivotally connected at 69 to a rotatable pawlcarrying disc 67 which through a ratchet 66 rotates intermittently the roller 71. The camshaft also rocks a lever 33 carrying the rollers 41, the latter projecting through slots in an upper tape guide 41 to press the tapes together. In use, lengths of filament are applied manually to the tape 1 at position 93, Fig. 2, and the motor switch operated. The rollers 54 descend to draw off the tapes 3 and apply them to the tape 1 over the filament. The pawl 68 slips over one tooth of the ratchet, and as the rollers 54 retreat, the roller 71 is rotated anticlockwise by the pawl 68 to advance the joined tapes by one unit. This latter movement coincides with an increase in pressure on the rollers 41 caused by the rocking of the lever 33. The tapes pass along a channel 83 into a drum 85. The guillotine comprises a blade 89 cooperating with an edge 90 and is operated after a desired length of filament-bearing tape has been produced. A block of foam rubber 92 cushions the tape during cutting. Tensile testing.-A single unit of Fig. 1 may be gripped at the margins la by the arms of the tensile testing machine and strips 1b severed. The strips 1a may be located on the arms by means of pegs through the holes 5.

Title: Ring rolling mill
IPC: B21H1/06
Filed: 1973-05-08
Abstract: 1427019 Rolling rings RHEINSTAHL AG 8 May 1973 [9 May 1972] 21753/73 Heading B3M A ring rolling mill comprises rolls 1 and 2 (Fig. 1) acting on the external and internal surfaces of a workpiece ring 5, and two frusto-conical rolls 3 acting on the end surfaces, the peripheral speeds of the four rolls being maintained equal during rolling. In one form, the speed of one of the two rolls 3 (only one is driven) is controlled in response to both the speed of the driven roll 1 and the position of the ring as detected by sensors 16. If the ring tends to shift laterally during rolling, a differential signal from the two sensors is generated at 18. This causes the speed of the roll 3 to be modified in a sense to return the ring to. its central position. Centering rollers 6, which are moved outwardly on arms 7 as the ring expands, may be used as sensors in place of the sensors 16. Either the rolls 3 or the rolls 1 and 2 may be shifted along the mill frame during rolling, to maintain the axes of the rolls 3 at the centre point 4 of the ring. In another form, Fig. 4, the axial positions of the rolls 3 may be adjusted, rather than their speeds, using an actuator 25. As before, the actuator is operated in response to differential movement of sensor rollers 6, indicating a lateral shift of the ring. This differential movement is detected in a bridge 29 and an error signal is fed to the actuator 25. Simultaneously, as throttle unit 31 associated with the roller which has. been shifted most is controlled such that its throughflow is changed and the roller produces a force on the ring tending to restore it to its central position. A speed control unit 23 acts with a tacho-generator 11 to give initial speed adjustment of the roll drives.
