Title: Fault current protective device
IPC: H02H3/347
Filed: 1974-09-30
Abstract: 1485968 Earth leakage protection systems SIEMENS AG 30 Sept 1974 [28 Sept 1973] 42401/74 Heading H2K An earth leakage protection arrangement comprises two core-balance transformers 3a, 21, the first having an alternating current injected (14) into its secondary so that it acts as a magnetic amplifier to trip the circuit breaker 9 on occurrence of a steady D.C. fault, the second acting in the normal way to trip the breaker on occurrence of an A.C. or pulsating D.C. fault. The two transformers are connected to coils 7, 25 which control either separate actuators 20, 27 or a common actuator. The first transformer may be replaced by a pair of core-balance transformers in a bridge circuit as described in Specification 1,359,848. The second transformer 21 may have a core with a high "induction swing" and "relative pulse permeability" as described in Specification 1,369,817 or a tuned secondary winding as in Specification 1,359,714 to ensure that it responds equally to both A.C. and pulsed D.C. faults.

Title: Improvements in or relating to planographic printing
Inventor: BRICKNELL KENNETH
IPC: B41N1/14
Filed: 1961-11-28
Abstract: 1,025,842. Printing surfaces; etching. DICK CO. A.B. Nov. 8, 1962 [Nov. 28, 1961], No. 42536/61. Headings B6C and B6J. An imaged paper-base master for use in planographic printing is produced by imaging the surface of an oleophilic paper base, subjecting the imaged surface to the action of a pre-etch solution comprising an aqueous solution of a polyvalent metal salt such as zinc acetate, and then subjecting the imaged surface to the action of an aqueous etch solution containing an anion which reacts with the metal cation in the pre-etch solution to form an insoluble or sparingly soluble precipitate. The paper base used is described as non-lithographic, i.e. its imaged surface is incapable of being used directly in planographic printing when subjected to the action of, for instance, an aqueous phosphoric acid etch solution. The metal salt may be a salt of zinc, nickel, calcium, copper, cobalt, iron, lead, magnesium, cadmium, barium, manganese or aluminium. The salt may be derived from an organic or inorganic acid and suitable acids include acetic acid, hydrochloric acid, nitric acid and sulphuric acid. The pre-etch solution includes a hydrophilic colloid such as methyl cellulose, gum arabic, gelatine or polyvinyl alcohol to ensure good pick resistance and rapid pick-up of image, and a suspension of inert colloidal solids such as silica to improve the running properties of the master and to make it more robust. The pre-etch solution may also contain a surfaceactive agent, such as a condensation product of ethylene oxide with alkyl phenols, to improve wetting of the paper base. The etch solution may be a phosphoric acid solution with sodium dehydrogen phosphate and may contain a humectant, such as glycerol, to prevent drying out too quickly and also a wetting agent. Examples are given of compositions for suitable pre-etch solutions.

Title: Manufacture of pile fabrics
IPC: D06B11/00
Filed: 1976-12-08
Abstract: 1533417 Loop dyeing of yarns; pile fabrics; warping I L THATCHER 8 Dec 1976 [24 Oct 1975] 43690/75 Headings DIE D1K and DIL Yarns for the manufacture of pile fabrics are space dyed after having been looped into individual pockets 14, one loop for each pocket 14, by individually dyeing the loops by individual portions of dyestuff. The pockets 14, e.g. of square section, are provided in circumferential rows on the periphery of an intermittently rotatable drum 10. The yarns are looped into the pockets 14 by reciprocable needles 26 of a yarn inserting bank 24. Dye liquor is applied to the pockets 14 by units 18 each comprising individual heads arranged axially of the drum 10. Each unit 18 dispenses only dye of a single colour and the units 18 are under the control of a patterning mechanism so that, upon receipt of a signal, each unit 18 is lowered so that a charging nozzle 20 thereof extends into the pocket 14 therebeneath to dispense dye therein. The drum may be heated internally to expedite the dyeing of the loops or the dye may be fixed by heat, e.g. steam, after withdrawal of the loops from the pockets. The yarns are subsequently used for forming the pile of a pile fabric, e.g. by tufting or weaving and may be straightened out and beamed before use. Alternatively, the yarns are looped by being tufted through a backing fabric into the pockets. In the latter case, the dye dispensing heads are inside the drum and a backing fabric overlies the outside of the drum so that the loops are formed through the backing and cut from the opposite side of each pocket. In modifications, the pockets may be defined by circular section holes in the drum periphery or by two opposite and helical sets of plates to form diamond-shape holes, or the pockets may be formed in an endless belt or a chain structure.

Title: Drive mechanism for an axially movable and rotatable tool holding spindle
IPC: B23Q5/16
Filed: 1966-09-30
Abstract: 1,138,848. Change-speed gear; planet gear; worm gear; positive clutches. GORTON MACHINE CORP. 30 Sept., 1966 [19 Oct., 1965], No. 43815/66. Headings F2C, F2D, F2Q and F2U. [Also in Division B3] A change-speed gear for driving the workspindle 7 of a machine tool from an electric motor M comprises an expanding wheel gear 49 in series with a two-speed toothed belt gear D. The pulleys 13, 46 of the expanding wheel gear are respectively rotatably fast with the motor shaft 12 and a layshaft 41 and each pulley has an axially fixed flange 13a, 46a and an axially movable flange 13b, 46b. Axial adjustment of the flange 13b is effected by an electric motor (14), Fig. 15 (not shown), which drives through a torque limiting slip coupling (19) a screw (15) carrying a nut runner (20) that is connected to one end of a lever 22 which is pivoted at 23 and connected at its other end to the flange 13b. A projection 25 on the fever 22 engages stops 26, 27 to limit movement of the flange 13b. A spring 47 urges the axially movable flange 46b of the driven pulley 46 towards the axially fixed flange 46a. The layshaft 41 selectively drives an output sleeve 30 through a high speed belt and pulley gear train 60, 63, 34 or through a low speed belt and pulley gear train 45, 45a, 44, 38, 37, 36, 35, Electromagnetically-operated positive clutches C, C1 are selectively engaged for low and high speed ratios. Each clutch comprises an electromagnet 55 rotating with its shaft 41 and an armature plate 58 splined to its pulley 60. Energization of the electromagnet draws the plate 58 towards the magnet to engage clutch teeth 56, 57. The output sleeve 30 is splined to the workspindle 7 and spring-pressed balls 70 (Fig. 8) act between the splines to prevent backlash. The workspindle 7 is carried by a non-rotary sleeve 6 having rack teeth 72 engaged by a pinion 73 on a shaft 74 which is rotated by a handle 9 or motor PF to raise or lower the workspindle. An overdrive planet gear is interposed between the handle 9 and shaft 74. Planet pinions 76 carried by the hub 79 of the handle 9 mesh a fixed ring gear 82 and a sun gear 80 fast with the shaft 74. The motor PF drives the shaft 74 through a positive clutch 151 and a worm wheel 133 and pinion 134. Rotation of a handle 150 causes an eccentric pin 150a to move the pinion 134 axially out of mesh with worm 133, whereupon the pinion 133 and a depth indicator disc 140 may be rotated to zero the depth indicator by a handle 136.
