Title: Method of and device for inspecting webs of fabric or wire gauze for the purpose of detecting mechanical flaws therein
IPC: D06H3/10
Filed: 1964-04-15
Abstract: 993,621. Inspecting fabrics. R. LIEBERKNECHT, and M. LINDENMEIER, [trading as HELIOS-WIRKMASCHINEN-ZUBEHOR ZWINGENBERGER & CO.]. April 15, 1964 [June 15, 1963; Aug. 17, 1963], No. 15522/64. Heading D1S. A method of inspecting a web 12 of fabric or wire gauze to detect mechanical flaws therein is characterised in that the web 12 is scanned on one side simultaneously by two control channels which cause air to be passed through the web 12 and that the pressures in both channels are compared so that at the occurrence of a flaw due to thread breakage or snatched up threads the machine producing the web or transferring the web to the inspection station is stopped. As shown, a scanning head 13 moves to and fro across the web 12 in the direction indicated by arrows 14. Compressed air enters the head 13 through a conduit 15, Fig. 1, and passes through throttles 1, 10, chambers 2, 7 and nozzles 4, 5 to pass through the web 12. The chambers 2, 7 are connected by channels 3, 8 to pressure chambers 30, 31, respectively, separated by a disphragm 6. Any change in density of the web 12 cause pressure variation in the chambers 2, 7 and hence in the chambers 30, 31 so that the position diaphragm 6 is shifted and through a stem 9 closes contacts 11. The contacts 11 close a control circuit 16 so that current flow via an amplifier 17 to a rest contact relay 18 to break the main circuit 19 and arrest the machine producing the web or transferring it to the inspection station. In a modification (not shown), suction is applied to the conduit 15 to draw air in through the web 12. The head 13 is mounted by a forked rod 29, Fig. 2, on a carriage 21 movable along a rail 20 between abutments 23, 24 by a pull rope 22 passing around rollers 28 and driven by a motor 25. The conduit 15, preferably a flexible tube, establishes the connection between the head 13 and a switchbox 26. An alarm lamp 27 may be provided to indicate the detection of a fault in the web 12. In a modification (not shown), the web 12 is moved past the stationary head 3.

Abstract: 951,101. Aerosol containers. J. LYONS & CO. Ltd. July 4, 1960 [May 6, 1959], No. 15524/59. Heading F1R. [Also in Division F2] A metal seat-carrying member is retained in the opening of a container of pressurized fluid by a spun peripheral flange 10, the member continuing in a depending portion 11 leading to a re-entrant part 12 which terminates in a central orifice 13 that supports an annular seat 14 of resilient material e.g. silicon rubber. A flexible metallic strip 15 with a dome 17 is diametrically disposed across the part 12 and is located in a groove in the latter; the dome 17 seats on an annular edge of the seat 14 due to the resiliency of the strip 15 and the pressure of the fluid in the container. The strip 15 may be plain or embody two parallel corrugations 26. The dome 17 is unseated by an actuator of moulded plastic material having a cylindrical stem 20 incorporating a finger part 21, an outlet nozzle 24 with a cruciform opening, and a depending projection 22 that passes through the orifice 13 and abuts the dome 17. The actuator has two internal lugs 23 that engage recesses in the metal member, which arrangement both locates the actuator in the latter and provides a fulcrum about which the actuator pivots when the finger part 21 is depressed to open the valve; the lower edge of the actuator is inclined. The actuator is formed with a tongue 25 which prevents accidental operation of the valve during transit; before use the tongue is broken off. The actuator is readily removable to permit of sterilizing the valve and container.

Abstract: 420,527. Linkwork. WATERDALE DYEING & FINISHING CO., Ltd., and GORDON, E., Mere Clough, Prestwich, Manchester. May 30, 1933, No. 15535. [Class 80 (iii)] An oval drum a is driven at such a variable speed that the linear velocity of points on the circumference is constant at a certain point in space, for example, the point of taking-off of a web of material into a dye bath. A driving-pulley e is fast to a plate f having diametral slots containing slides g on which are mounted pins h each carrying a pair of rollers h<2>, h<1>. The first of these move in arcuate slots in a carrier i and the second in a groove in a fixed cam plate d, the groove being similar in shape to the drum a. The carrier i is fast to the drum, the speed of which is therefore varied by the contour of the cam groove. A plate having pivoted arms the ends of which may move in curves similar to the slots in the carrier i, may be substituted for the latter. Pivoted arms may also be substituted for the diametral guide slots in the plate f.

Title: Improvements relating to coated metal ligatures
IPC: B05D7/16
Filed: 1963-04-19
Abstract: A metal ligature, e.g. a steel strap, having a thin flexible protective coating, is produced by applying to the ligature a thin film of a solution in an organic solvent of oily butadiene polymer having a low molecular weight and containing dispersed therein a proportion of flake aluminium in a sufficiently finely divided condition to permit it to pass through a 400 mesh screen, and heat curing the applied film, e.g. at a temperature in excess of 600  DEG F.  The solution may contain between 0,5 and 4 lbs., e.g. between 1 and 2 lbs., of the flake aluminium per gallon.  The polymer may contain at least 75% by weight of copolymerized butadiene-1,3, having an average molecular weight, determined by boiling point elevation in ethylene dichloride, of between 1000 and 30,000, e.g. between 5000 and 15,000, any balance of the polymer being constituted by copolymerized mono-ethylenically unsaturated monomer, e.g. vinyl toluene, styrene, or up to 2% of ethylenic monomers containing a carboxyl group and especially dicarboxylic acid anhydrides such as maleic or citraconic anhydride.  The polymer may be partially oxidized to an acid number in the range 5-25.  The polymer may be a copolymer of butadiene and styrene, and may contain approximately 10% by weight of copolymerized styrene.  The proportion of dispersed flake aluminium may be from 0,13 to 1,0 pounds per pound of the polymer, e.g. 0,26-0,52 pounds per pound of heat-cured butadiene-styrene.  The butadiene copolymer may be employed alone or in combination with other synthetic resins, e.g. solvent-soluble heat-hardenable urea-formaldehyde resin.  The coating composition may be applied as a solution in an organic solvent, and the thickness of the film may be from 0,1 to 0,5 mils, e.g. from 0,2 to 0,4 mils.  The coated strap may be printed or waxed.

Title: Flow control system
IPC: G05D7/06
Filed: 1974-04-09
Abstract: 1481021 Automatic control systems NATIONAL RESEARCH DEVELOPMENT CORP 26 March 1975 [9 April 1974] 15764/74 Heading G3R The mean velocity of flow of particles in a fluid is controlled in response to the difference between measured and desired values of the velocity spectrum. It is desired to transport material as slowly as possible commensurate with there being no blockage; it is explained that the width of the substantially guassian velocity spectrum, which is a function of the mean velocity, is an indication of the conditions of turbulance of the particles. The measurement is made using two conductivity, capacitive or electrodynamic transducers 24, 25 spaced apart in the direction of the flow and from which the spectrum is derived at 26, 29, 30 using a "cross correlation technique" described in Specification 1235856 (Division G1). 26 is a short term correlator having an integration time of 1 see; its output U is the mean velocity which is compared at 27 with Ud, the velocity required to produce the desired spectrum, any difference forming a control signal to adjust the flow of fluid from pump 23 at valve 22. The value Ud is derived from a comparison at 31 of the two quantities according to the invention. The correlator 29 for this purpose has an integration time of 30 secs. The system may be given an anticipating element by modifying Ud by a signal corresponding to the rate of change of solids mass flow, measured by 33 at the point of injection 21. A simpler arrangement in which the output of a comparator like 31 controls the fluid flow directly is described, Fig. 5 (not shown). The contents of the "boxes" are not described but 30 is a digital calculator.

Title: Improvements in or relating to belt or band conveyors
IPC: B65G39/16
Filed: 1941-12-08
Abstract: 552,697. Conveyers. GARNETT & SONS, Ltd., C., and BARKER, A. P. Dec. 8, 1941, No. 15787. [Class 78 (i)] A device for maintaining the band or belt, of a conveyer in its medial position comprises one or more pairs of wheels &c. 6 carried by brackets 5 mounted on springs 9 attached to a common base piece 10. The brackets 5 have pintles 4 which can both slide and turn in a fixed framework 2, the pintles 4 preferably being off-set relative to the axles 8 of the wheels 6. The piece 10 is of U-shape and encloses the edge of the belt so that when the latter moves laterally beyond its proper limit it forces the U-piece along with it and turns the wheels 6 about their pintles 4. As the springs 9 press the wheels 6 on to the respective surfaces of the belt 1 this steering of the wheels 6 imparts a lateral pressure on the belt tending to restore it to its medial position. A pair of wheels 6 may be located near each edge of the belt, the two U-pieces 10 then being connected by a pivoted link 11. In a modification the framework 2 is journalled by connecting arms about the spindle of a near-by idler roller, and the link 11 may have a curved under face to rest on the belt 1 and be weighted to act as a tensioning member for the belt.

Title: Improvements in tool setting devices, mandrels or reamers for taper work
IPC: B23D77/12
Filed: 1919-06-23
Abstract: 150,129. Gray, W. H., and Hurd, B. H. June 23, 1919. Turning; reamers; mandrels.-In a tool for reamering, gauging, or holding tapered work, of the type in which a series of blades are angularly adjustable in longitudinal grooves in a. spindle so as to vary the taper, the adjusting means engages the blades on their ends. In the form shown in Fig. 5, for reamering tapered holes in metal &c., or for use as a gauge or pattern from which to determine the form of a tapered shaft to fit the tapered hole, the spindle is formed with a tapered barrel portion 2 and screwed portions 3, 4. The barrel portion is formed with a series of grooves 5, preferably with arcuate bottoms, to receive the blades 6, the grooves extending into the body of the spindle at each end. The bottoms of the blades are preferably curved as at 8, Fig. 8, to obtain a face contact with the grooves in all positions of adjustment, and the bevelled ends of the blades are preferably similarly curved as at 10, Fig. 8, to seat solidly against the external curved overhanging surfaces of the adjusting-nuts 12, 14. The front ends of the blades are preferably slightly narrower than the rear ends to provide for a larger taper. The blades may also be adjusted so as to produce a cylindrical reamer or gauge. When used as a gauge, the tool may first be inserted into the tapered hole to set the blades and then mounted in a lathe, a test indicator or pointed tool in the compound tool-holder being then moved along the straight edge of one of the blades, the compound tool-holder being thus set to obtain the desired taper. Tapered holes may be duplicated in a similar manner, the small end of the gauge in this case being at the headstock end. The hole is roughed out with a boring-tool, and is finished by the reamer described. If no mandrel is available, the compound tool-holder is first set to produce the desired taper, the tool then mounted in the lathe and the slope of the blad'es thus adjusted. The hole is then roughed out by a tool in the compound tool-holder, and then finished by the reamer. The tool in the form shown in Fig. 9 may be used as a mandrel for mounting a piece of stock S. In this case the end nut 14 may be replaced by, or used in addition to, a nut 20 recessed to receive the ends of the blades, the face 22 of the nut gripping the stock and forcing the blades against the adjusting-nut 12. The nut 20 may extend the entire length of the threaded portion 4 for supporting and strengthening purposes, and may be recessed sufficiently to receive the nut 14.

Abstract: 572,446. Dehydrating food &c. BLACKALL. S. W. E. Sept. 28, 1943, No. 15943. [Class 34 (ii)] [Also in Group X] Material, e.g. food, supported on a vertical tier of perforated trays 16 in a cabinet 10 is dehydrated by subjecting it to a heated atmosphere, preferably air, which passes in a closed circuit upwardly through the cabinet in a sinuous path across the trays, and then through a conditioning chamber 29 in which it passes through a water shower or curtain to cool and wash it, and through a heater before returning to the cabinet. The curtain of water falls from a perforated channel 30 at the top of the conditioning chamber to a grating at the bottom, to condense absorbed moisture. A perforated metal plate, sheet of cotton mesh or row of metal bars 43 prevents the cooling water from being carried forward from the chamber 29. The air then passes between pivotally adjustable baffles 35 and electric heaters 36 to the fan 37 which returns it to the bottom of the cabinet. Each tray comprises a wooden frame 17 carrying a perforated metal sheet 18 with upstanding walls 19 one of which is recessed inwardly at 21 over the perforated metal sheet for the passage of gases. There are two vertical tiers of trays, which are so arranged that the recesses 21 are alternately at the sides and centre of the cabinet. At the top of the cabinet the air enters a central passage 40 through openings 41 at each side, and passes down through a rear conduit 42 to the conditioning chamber 29. Alternatively, the air returns from the top of the dehydrating chamber to the conditioning chamber through passages in the side walls of the cabinet. The air entering the cabinet may be at 130‹ to 170‹F.
