Title: Improvements in or relating to apparatus for severing sheets of material, as for cutting bag tubes into bag lengths
IPC: B31B19/14
Filed: 1928-04-24
Abstract: 300,165. Bates Valve, Bag Corporation, (Assignees of Kronmiller, C. G.). Nov. 7, 1927, [Convention date]. Delivery apparatus.-In apparatus for severing a collapsed tube into bag lengths, a flattened tube 137 passes from conveyers to a clamp 34, through cutting cylinders, to a clamp 38. The severed sheets are fed by a conveyer 144, 152 and alternate sheets are diverted by a deflecting finger 157 or by pneumatic means to an upper conveyer 173 and a lower conveyer 178. The clamp 34, the cutting cylinder, and the clamp 38 are driven from an electro-motor through appropriate gearing at speeds slightly less than, equal to, and slightly greater than the speed of the web. Blades on a bar 63 slidable on arms 60 on a shaft 58 co-operate with recesses in a bar 112 carried by arms 110 on a shaft 108 to cut lengths with corner extensions differentlv directed. The ends of the bar are connected by gearing and are retracted by an adjustable stationary cam. Springs 68 move the bar forward to effect the cut. A clamp bar secured to an arm 60 engages a clamp on the bar 112. A cutter 106 engages a recess 135 for severing the web transversely. Within the bar 112 slide pins operated by cams for removing the rectangular waste portions. The cut lengths are received between the conveyer 152 on pulleys 149, 150, 151 and the conveyer 144 on pulleys 141, 142, 143, arranged as in Fig. 3. The conveyer 152 at its rear end co-operates with the conveyer 173 passing over pulleys 170, 171, and the conveyer 144 co-operates with the conveyer 178 on pulleys 169, 177. The deflecting finger 157 is operated by a bar 164 oscillated from the cutter mechanism and carrying pins 167, 168 which engage a toggle. The leg of the toggle is telescopic against the action of an enclosed spring to allow the deflecting finger to become inoperative if the cut between the sheets is defective. In a modification the finger 157 is replaced by upwardly and downwardly directed air jets. Specification 290,158, [Class 78 (i), Conveyers &c.] is referred to.

Filed: 1969-03-07
Abstract: 1,185,620. Distribution systems. E.M.S. ELECTRICAL PRODUCTS Ltd. 7 March. 1969, No. 12066/69. Addition to 957,128. Heading H2E. An electrical distribution system as claimed in claims 1-6 of Specification 957,128 comprises a conductor-containing duct made up from mating longitudinal halves 10, 11, e.g. of extruded aluminium, which are pivotally inter-connected so as to allow relative transverse movement. This is achieved by a flange 13 on half 11 having a laterally projecting hook element 33 which fits into a complementary groove 35 in a flange 12 on half 10. Spacer elements 37, located at points along the duct, fit over thickened portions 18a, 19a of bottom walls 18, 19 to prevent the width of a longitudinally extending slot 20 in the duct increasing. The thickening of portion 18a is greater than that of portion 19a to ensure that a tapping conductor, intended to be inserted longitudinally and then turned through 90 degrees to contact conductors 24, 25, 29, 30, 31, can only be turned in the direction to achieve correct polarity. A cover-plate 40 secures longitudinally extending side plates which protect the end to end connection between successive lengths of duct. Continuity of conductors is achieved by overlapping conducting members (43, Fig. 2, not shown) in sockets (44) on adjacent duct ends. Both the sockets (44) and conductors are supported on connectors 46 of insulating material, having formed on them integral strips 48 which engage the mouths of the conductor-carrying channels and have recesses for receiving the sockets (44), as have the side-walls of the duct. The duct may be supported by jawed clamping bars (not shown) gripping enlargements 32, 34 on flanges 12, 13.

Abstract: 575,028. Proofing against fire and water. KNAGGS, J. Sept. 19, 1941, Nos. 12134/41, 846/42 and 7638/42. [Class 140] Fibrous materials, e.g., fabrics, string, rope, netting and kapok are rendered flame-proof and water resistant by impregnation with a solution in a volatile organic solvent of an organic phosphate, e.g., triphenyl or tricresyl phosphates, with or without an organic borate such as amyl borate, and a water-insoluble metallic salt of a higher fatty acid such as aluminium or calcium stearate or palmitate, lead linoleate or calcium oleate. The material may be treated successively with two or more solutions. It may be treated prior to impregnation with an aqueous solution of ammonium phosphate or borax, or with aluminium, man-. ganese, magnesium, copper and barium phosphates, borates, e.g., magnesium ammonium phosphate. The organic solvent solution may include asphalt, lanoline, beeswax or wool wax, urea, chlorinated rosin, chlorinated oleic acid and chlorinated rosin or ester gum or their aluminium, calcium, copper or zinc salts, polyvinyl chloride, and chlorinated derivatives of rubber, gelatin, casein or albumen. Dyestuffs and preservatives such as chlorinated cresol, chlorinated naphthalene copper and zinc stearates, naphthenates and palmitates may be added. Suitable solvents are white spirit, benzene, dichlorethylene and methylated spirit. The impregnation may be effected with the acid of vacuum. In examples 10 the fibre is treated with a solution of magnesium sulphate and ammonium hydrogen phosphate acidified by dilute hydrochloric acid, squeezed and immersed in aqueous ammonia to precipitate magnesium ammonium phosphate on the fibres. Instead of ammonia alone an aqueous solution of casein and ammonia followed by a solution of lime may be used to precipitate calcium caseinate as well as magnesium ammonium phosphate. A solution of calcium oleate, tricresyl phosphate and beeswax in benzene is finally applied; 11 the last two steps are combined by using an emulsion formed from casein, ammonia and lime in water and a solution of tricresyl phosphate, amyl borate and lead linoleate in white spirit; 12 a single bath is used, made by mixing aqueous solutions of magnesium sulphate and ammonium phosphate and casein, ammonia and lime with aluminium hydroxide or china clay and emulsifying with, the white spirit solution of example 11. Specifications 7899/14, [Class 140], 404,691, 535,058 and 535,653 are referred to.

Title: Variable speed master-slave motor control system with  continuous phase adjustment
IPC: H02P5/52
Filed: 1972-03-16
Abstract: 1353420 Automatic control of speed BORG - WARNER CORP 16 March 1972 [13 April 1971 22 June 1971] 12258/72 Heading G3R In a system in which at least two A. C. motors, e.g. driving separate but interrelated conveyers, are energized by respective inverters, the speed of one (the slave) is controlled with respect of the other (the master) by an arrangement in which the frequency of the slave inverter is adjusted by a voltage (on line 44) derived by combining (at 80) two ramp signals of opposite slope each produced (in digital-to-analogue converters 72, 85) by digital counters 67, 84 which count pulses produced by respective voltage controlled oscillators 26, 42 which also control the inverters, the counters and ramps being reset by respective signals from position detectors 47, 50 associated with each motor or its driven member. Thus, the members are driven in synchronism and the phase relationship between them is maintained at a fixed but adjustable value. Adjustment over a limited range is made by adding a voltage from a potentiometer 55 to the junction 80, but for adjustment over a wide range a pair of inversely connected potentiometers are used, one associated with slave detector 50 and the other with a second slave detector 250, spaced 180 degrees from the first. Change over from one to the other is effected by a switch, actuated by a cam on the potentiometer shaft, operating through logic circuits and transistor switches Fig. 6, (not shown). A further voltage is added or subtracted at the point 80 if the two drives are out of synchronism. This is detected in phase detector 60 by the occurrence of two consecutive master or slave pulses; a logic 1 is produced on line 111 and a 1 or 0 on line 112 according to whether the slave is over or under speed. These logic signals switch transistors connected to Zener controlled voltage sources in "out-of-sync" circuit 110, which is described Fig. 5, (not shown). Resister 99 provides a "setting up" adjustment to allow for the particular relationship of the frequency of position and inverter pulses. The detectors 47, 50, 250 may be magnetic or optical devices co-operating with appropriate spaced marks in respective conveyer belts.
