Title: Method of and apparatus for continuously producing preformed fibrous pads
IPC: D04H1/00
Filed: 1961-06-27
Abstract: 928,270. Agglutinated fibrous fabrics. R. DILO. June 27, 1961, No. 23181/61. Class 42 (2). A method of continuously producing preformed pads of fibres, e.g. animal hair, vegetable or synthetic fibres, bonded with a liquid binding agent, e.g. latex, or a dispersion of a synthetic resin, comprises the steps of depositing a fleecy sheet on a first endless conveyer band, conveying the fleecy sheet to a shoot, applying liquid binding agent in the form of a curtain flowing from an adjustable supply device to the fleecy sheet on the shoot, soaking the wetted fleecy sheet with binding agent by passage through pairs of rollers and conveying the soaked fleecy sheet on to a second endless conveyer band. As shown, a fibrous strand 1 is fed by feed-roller 23 into a strand-disintegrating device whereby it is formed into loosened-up fibres 3 which are conveyed by an air current through conduit 26 to distributer 5 and thence to volumetric hopper 4 having at its discharge end a pair of rollers 6 which extract the fibres from hopper 4 in the form of a uniform fleecy sheet 7 and deposit it on endless conveyer 8 whereby it is conveyed to shoot 29. Liquid binding agent is supplied, from a supply source, through pipe 13 to basin 9 whence it flows over overflow 10, of width corresponding to that of sheet 7, in the form of a curtain 11 on to sheet 7 on the shoot, to produce fleecy sheet 12 wetted with binder. Sheet 12 then passes between pairs of rollers 14 whereby it is compressed to ensure soaking of all the fibres, with binder. Cylinder 15 fitted with garnett wire is arranged to tease fleecy sheet 12 and disperse it on to endless conveyer band 16, having a variable drive. By varying the speed of conveyers 8 and 16 various transverse forms of profile may be produced on the fleecy sheet, as shown in Fig. 2, and similar longitudinal profiles 17 may be produced by inserting rods in perforated plates 28 see Fig. 3 (not shown), to vary the area of the distributer 5. The amount of liquid binder delivered to the sheet 7 may be varied transversely of the sheet by making the pipe 13 adjustable, or longitudinally of the sheet 7 by giving the edge 10 of the basin 9 a suitable profile. When synthetic fibres are used, they are preferably admitted horizontally on the band 8. The impregnated sheet 12 is passed to a drier and to a moulding apparatus.

Abstract: 339,277. Robinson, E. Y., and Associated Electrical Industries, Ltd. July 29, 1929. Vacuum tubes. - Indirectly-heated cathodes comprising an outer tube separated from the heater by an insulator are positioned by means which slidably engages the tube or the insulator to prevent lateral movement, longitudinal movement being prevented by a flexible member providing a universal joint. Deformation of the cathode tube by welding on a thick support wire is thus avoided. The cathode 10, Fig. 3, may slide at its ends through apertures in mica plates 18 through which pass the anode supports 2 and grid support 6, the plates 18 being held on the supports 2 by welded wires 19. The cathode 10 is held against longitudinal movement by a thin. short, molybdenum wire 22 longitudinal of, and secured to, the cathode 10 at the top or bottom and serving as a universal joint, and also a lead to the cathode. The grid support 6 passes freely through the upper plate 18 and is positioned by a mica plate 20. The anode has heat radiating fins 17. The tube 6 mav be shortened and the insulator inside it may extend beyond it to engage the mica plates 18. In another arrangement, Fig. 2, the cathode 10 constructed as in Specification 278,787 passes at its upper end through an aperture in a metal strip 11 on a lead-in wire 12 and is welded to a thin, short, transverse wire 14. In other arrangements, the cathode tube or its insulator slides within a tubular guide 24, Fig. 6, at one end, or the cathode tube slides over a guiding rod, a wire 25 preventing longitudinal movements. The guide 24 may be formed by drilling a wire out at one end, or by a split tube filled at one end with a wire 26. The cathode tube may be applied to the insulator by spraying or by winding with tape, and the wire 25 may be wound about the insulator or replaced by an extension, of the tape. Specifications 307,857 and 322,827 also are referred to. The Provisional Specification describes also registration of the cathode at each end by metal cross-pieces on wires extending from the pinch. Specification 223,293 also is referred to. Reference has been directed by the Comptroller to Specificaton 346,096, [Group XL].

The stacks are mounted between discs 15, 16, that can be rotated in recesses in top and bottom plates 17, 18 by a hand-actuated crank. A counter 31 registers the number of tokens issued and perforations are made in the sides of each stack so that the attendant can observe the number remaining in the stack. A special thick token that cannot be discharged by the ejector plate is arranged on the top of the tokens in each stack to indicate when they are exhausted. The ejector plate is operated by a hand-lever 24 that simultaneously rings a bell 50. The passenger, on reaching his destination, places his token in a cup 90 of the collecting device, Figs. 4 and 5, whence it falls into a shoot 91 having a ledge 94 on one side; undersized tokens or coins slip from the ledge and pass through an - opening 96. After passing down the shoot the tokens reach a temporary deposit chamber 92 from which they are transferred by a handactuated lever 100 into the appropriate one of a series of token stacks similar to those of the distributing-device. The stacks are rotated in accordance with the zones passed through by a crank-handle 82. The lever 100 is provided with a curved end that sweeps the token in the chamber 92 past an elimination opening 105 to an opening registering with the upper end of a stack into which the token drops. A counter 109 is actuated by the movement of the token. To keep the tokens received in each stack during each journey separate a special token from a tube 115 is delivered into each token stack as it is moved into position below the receiving opening; the feeding device for these tokens is operated by a crank-pin on a pinion-actuated by the crankhandle 82. To assist the attendant in determining the fare the edge of the plate carrying the lower rotating disc of the stacks is marked with the appropriate fares from the zone corresponding to the stack in receiving position. Indicators showing the position of the car are fixed on and operated by the distributing and the receiving devices.

Abstract: 910,561. Switch contacts. PLESSEY CO. Ltd. July 20, 1959 [July 22, 1958], No. 23472/58. Class 38 (5). Contacts on the bifurcated ends of a resilient blade move relative to each other after engaging a fixed contact or contacts to produce a wiping action. Two pairs of such contacts 2, 3 and 4, 5 are shown in Fig. 1 on the ends of a spring 1. The limbs 10 . . . 13 are bent so that each pair of contacts is coplanar, the limbs 10, 12 being concave and the limbs 11, 13 convex when viewed from the direction of the fixed contacts 8, 9. When contacts 2, 3 engage the contact 8, the contact 2 is moved outwards owing to the decrease in curvature of the limb 10, and the contact 3 is moved inwards owing to the increase in curvature of the limb 11. Lugs 6, 7 on the spring 1 may be loosely mounted on contact-actuating means (not shown) so that if one contact sticks the wipe of another is increased. In Fig. 2 a spring blade 21, pivoted at 27, has bifurcated ends 24, 25 carrying contacts 22, 23 for engagement with contacts 28, 29 on a support 26. Owing to the differing contact heights they engage simultaneously but in different planes and further movement of the blade 21 results in relative movement of the points of contact. In a modification of this last arrangement, Fig. 3, the end of one arm 34a and one arm 36b of a bifurcated fixed support 36 are cranked; the heights of all the contacts being the same.

Filed: 1938-08-09
Abstract: 517,657. Grinding milling-cutters. 'LINDNER, H. Aug. 9, 1938, No. 23513. Convention date, May 5. [Class 60] In the grinding of screw-thread milling cutters 1 having helical flutes 2, a multi-ribbed grinding-wheel 8 of axial width less than that of the cutter is used, the grinding being performed in steps in which the cutter is moved axially by an amount equal to the pitch of the ribs or a multiple thereof after each rotation of the cutter and at the same time is given a partial rotation to bring the cutter teeth to correct position relatively to the grinding-wheel so that the relief may start correctly and produce a cutter in which the leading edges of all the teeth lie truly on a cylinder. The cutter 1, mounted on centres 4, 6, is driven by a shaft 5 carried by a workslide 37 and driven, through bevel, and worm gearing 10 ... 13 by a motor 9, the shaft 14 of the worm 12 also carrying the bevel' wheel 15 of a differential gear 15 ... 18, of which the gear 18 is connected to a worm'wheel 20 and mounted freely on a shaft 21; the wheel 20 is engaged by a worm 44 on a shaft 45. The shaft 21 drives through gearing 22 ... 26 a cain 28 which, through a bellcrank lever 29, rocks a lever 31 to oscillate the slide 37 on a pivot 38 to move the cutter for grinding relief thereon; the lever 31 has an adjustable pivot 32 and also may be adjusted, to adjust the position of the cutter, by an eccentric 36. After one groove between cutter teeth, or group of grooves has been ground all round the cutter, the slide 37 is moved a distance equal to the pitch of the grooves or a multiple thereof corresponding to the group, by a screw 46 operated by indexing-mechanism comprising a crank 51 and gearing 52, 54 ... 56. This brings the next group of teeth into position axially for grinding, but to ensure correct relieving of the teeth the cam 28 is given a slight rotation through the differential gearing by rotation of the shaft 45, by the shaft 50 carrying the gear 52 through gearing 57 ... 61; a further gear 63 coupled to the shaft 50 when required by a clutch 65, serves to return the slide 37 to its initial position when required. The grinding-wheel may have the ribs lying on a conical surface as shown in Fig. 5, and the grinding is done in three steps, with the wheel in the positions. b<1>, b<2>, b<3> respectively, the wheel being withdrawn at the lines GH, IK, LM for the three steps. In a modification, the wheel is of. conical form and has the ribs of successively diminishing size; in this case the wheel.is stepped after each grinding operation by one groove pitch, so that one tooth only at a time is finished. Fig 8 shows a form of cylindrical wheel and Fig. 9 another modification of conical multiprofile wheel. Specifications 464,332 and 500,112 are referred to.
