[Also in Division B5] A filter element, for the air intake or lubricating oil circuit of an I.C. engine, comprises a flat pleated panel of resin-impregnated paper, pleat ends joined to form pockets which open on one face to which a sealing strip 37, of polyvinyl chloride, is secured. Peripheral grooves 30 (Figs. 10-12, not shown) are indented in the pleat crowns, and the flange 45 of a peripheral metal or cardboard frame around the element engages the mould 31 into which the element is pressed and forces the liquid plastics into grooves 30 and between pleats. Frame 41 may be made in one or two pieces and forms part of the finished element. The element is passed through an oven with the mould, to cure the plastics and resin. In Figs. 10-21, the grooves 30 are formed by vibratory wheels or hammers in the uncured paper. In Figs. 4-9, not shown, the grooves are made by pressing the element down on to a central member (20) of the two-part mould in which the sealing strip is formed. In Figs. 1-3. not shown, strips (4) of stiffer plastics are applied to the element before the moulding step, which adds further plastics thereto.

Abstract: 253,449. British-American Laundry Machinery Co., Ltd., (American Laundry Machinery Co.). Dec. 31, 1925. 1'rotectors, controlling.-In a garment press having power-operated toggle links 8, 9 and a lever 11 actuated by a crank 57 and connected to the bottom of the lower link to raise the toggle to apply effective pressure regulated by an adjustable spring 16, if the normal closing is obstructed as by the operator's arm, the toggle does not assume full straight-line position and consequently no pressure is applied between the head and buck, the lower link merely sliding through the knuckle block 31 and past the lower end of the upper link. In such circumstances the motor continues to operate and the press performs a complete closing and opening cycle, automatic opening of emergency switches, not shown, in the motor circuit. Movement of the press is initiated by buttons in relay circuits, such circuits being broken at the end of the closing and opening operations by the automatic opening of normally closed switches, the opening of these switches being controlled by the pressure exerted and by movement of the press head lever respectively. Normally the motor rotates in opposite directions for closing and opening operations, but when the link slides through the knuckle block in emergency, the motor continues rotating in the same direction for both operations. A spring-applied, electromagnetically released, band brake for the motor shaft is included in the motor circuit.

Abstract: Staple or multifilament yarns or filaments of a synthetic segmented elastomeric copolymer e.g. spandtex, have a lubricating covering or coated finish of at least 0.5% by weight of an organic silicate ester which is an orthosilicate or dimer silicate in which each organic radical which is attached through an oxygen atom to a silicon atom contains at least six carbon atoms e.g. tetra-n-hexyl silicate, tetra-n-heptyl silicate, tetra-n-decyl silicate, tetra-n-octyl silicate, tetrakis (1-ethyl-pentyl) (2-ethylbutyl) or (2-ethylhexyl) silicate, hexa-octoxydisiloxane, hexakis (2-ethyl-butoxy or -ethylhexoxy) disiloxane or mixtures thereof.  The finish is applied, in visious or finely ground condition using a diluent, by dipping, padding or spraying and it may contain silicone oils, plasticisers for spandex such as polyethylene oxide esters of stearic acid, metal soaps such as zinc or magnesium stearate, and emulsifying aids such as morpholine oleate.  A multifilament yarn may be formed by coalescence of several filaments and then finished.  Several filaments may be finished, assembled into a continuous tow, stapled and spun: the fibres may be blended with inelastic fibres at the tow or staple stage.

Title: Tube ejector

Abstract: 1498244 Mounting reels on shafts BARMAG BARMER MASCHINENFABRIK AG 8 Aug 1975 [9 Aug 1974] 33155/75 Heading F2U [Also in Divisions D1 and B8] Windings 4 and 5 of band material are pushed off a cantilevered wind-up shaft 1 by moving an ejector 6 in the direction 7, a screw-thread connection 11, 12 between the ejector 6 and a head 8 causes the head 8, and therewith a friction surface 9 abutting the package 4, to rotate in a direction causing the packages 4, 5 and therewith the package supporting tubes 2, 3, to rotate in a direction permitting chuck elements on the shaft 1 to retract radially and thus release their grip on the internal surfaces of the tubes 2, 3. The pitch angle of the thread 11 is such that its tangent in smaller than the coefficient of friction between the surface 9 and the end face of the tube 2. Figs. 4 and 5 show a modified arrangement for use with a bobbin revolver 15. A fork 14, that is rigid with an ejector 16, is normally urged by a spring 19 into abutting relationship with a stop 21. When a package is fully wound, the revolver 15 rotates in the direction of the arrow 20 and this causes the shaft 1.1 to commence to enter the fork 14 whilst at its broken line setting in Fig. 5. Surrounding the shaft 1, Fig. 4, in a thrust ring 10 on which is a collar 22. The fork 14 enters this collar 22 and both of these items have friction areas such that the fork 14 holds the thrust ring 10 against rotation. The inertia of the still rotating package is such that relative rotation now takes place between the ejector head 8 and the now stationary thrust ring 10. This permits the aforesaid screw-thread connection 11, 12 to cause chuck elements on the shaft 1 to retract radially and so release their grip on the internal surface of the bobbin tube 2. The ejector 6 then moves towards the viewer in Fig. 5 to eject the wound package and its support tube 2. 0-rings 23 centre the ejector head while the winding shaft is in operation Securing bobbin tube to driving shaft.-As shown in Fig. 2, rollers 124 rest on inclined surfaces 113, 115 formed in the surface of the wind-up shaft. The rollers 124 project through openings in a sleeve surrounding the wind-up shaft. When the wind-up shaft is rotated clockwise relatively to the surrounding sleeve the rollers 124 run down the inclined surfaces and so retract inwardly to release the bobbin tube. When the wind-up shaft is rotated anti-clockwise relatively to the surrounding sleeve the rollers 124 roll up the inclined surfaces 113, 115 and so move radially outwardly to grip a bobbin tube mounted on the sleeve.
