Title: Improvements in or relating to magnetic transducing heads
Inventor: HARRISON HENRY MILBURN
IPC: G11B5/127
Filed: 1957-11-06
Abstract: 900,652. Magnetic recording &c. heads. ELECTRIC & MUSICAL INDUSTRIES Ltd. Oct. 22, 1958 [Nov. 6, 1957], No. 34543/57. Class 40 (2). The trailing pole of a record/erase -playback head is of greater width x than that of the leading pole y. Since the effective recording width is x but the playback width is ¢(x+y), unerased fringes, due to misalignment on re-recording, do not cause an interfering output on playback. The core may be formed by folding up a strip of material as in Specification 889,793, the pole y being then machined to width.

Abstract: 823,577. Laminates; agglutinated fibrous sheet materials. RAYBESTOS-MANHATTAN Inc. Nov. 22, 1956 [Nov. 28, 1955], No. 35735/56. Drawings to Specification. Class 140. [Also in Group XXVIII] Composite sheet material comprises a parallel glass thread layer and a felted fibrous sheet layer composed of the dry residue of a composition comprising a colloidal dispersion of chrysotile asbestos fibres in an aqueous vehicle containing chrysotile asbestos dispersing agent, said material being fully saturated with and the layers cohered by a thermosetting, but not yet fully set, resin binder. The glass thread layer may be faced on one or both sides with the asbestos sheet material, or an asbestos layer may be disposed between two layers of glass threads. Multilayer laminates may comprise a substantially homogeneous matrix of thermoset resin binder and dry residue of asbestos composition as above enveloping and spacing a plurality of layers of parallel glass threads. The layer structure may be formed by impregnating with a solution of a thermosetting resin and bringing into surface contact a layer of parallel glass threads and a felted asbestos layer as above, drying the assembly to substantially remove the solvent and to cohere said layers, and recovering the resulting composite sheet material with the resin in a partially advanced but still thermosetting condition. A plurality of plies of such composite sheet material may be laminated together under heat and pressure. Resins referred to are of the polyester, epoxy and phenolic types. The glass threads may be treated with known keying agents, e.g. organic derivatives of chromium or silicon such as allyltrichlorosilane. The asbestos sheet material may contain a minor amount of asbestos fibres not colloidally dispersed or of glass fibres. Tubes may be wound from the composite sheet material. Laminates formed by impregnating and hot-pressing from the asbestos sheet material without any layers of parallel glass fibres, and also from ordinary asbestos paper and from corded asbestos fibre webs are described by way of comparison. Specification 689,692 is referred to.

Title: Improvements in or relating to a process and apparatus for making a systhetic plastics material filament coil
Inventor: BURBANK JOHN EMERSON
IPC: B29C53/12
Filed: 1964-09-01
Abstract: 1,080,321. Moulding sliding-clasp fastener stringers. SCOVILL MANUFACTURING CO. Sept. 1, 1964, No. 35815/64. Heading B5A. A sliding-clasp fastener stringer is made by winding a synthetic plastic filament F, e.g. of nylon, about a mandrel 41 to tightly enclose two inelastic strands S and C, the coiled filament being removed from the mandrel by tension applied primarily to the cords. In operation, a filament F, is led from a freely rotatable reel (30), Fig. 1 (not shown), and strands (S) and (C) of different diameters are taken from reels (63), (62) respectively through a stationary tube (35) and along the length of a mandrel 41, Fig. 3, fixed thereto, the filament F being wound under tension around the strands and the mandrel 41 subsequent to shaping action at a die 47. The die 47 is rotatably mounted in a rotating carriage 25 and performs one revolution about its own axis for one revolution of the carriage. Heads are formed on the filament by a tool (50), Fig. 7 (not shown), actuated by a cam (52) and at the same time the longer sides of the coils are flattened against die (47) by a tool (51) whose arms (54), (55), joined by a resilient cross-piece (56), are urged together by pusher slides (58) actuated by cams (59b), (60b). A further cam 61 may be used to provide heads opposite to those formed by cam (62). The filament F is unwound from die (47) in its passage to mandrel 41, Fig. 3, but the " memory " characteristics of the material facilitate resumption of coiling about the mandrel and the tight enclosure of strands S and C which tend to resume positions at opposite ends of the mandrel, see Fig. 8 (not reproduced). The formed coil is taken off by a drum 65, notched at its periphery 66 to receive the heads, the coil being heated to set by a shoe 73 and subsequently stripped from the drum by an idler wheel 75. A second embodiment of tool (51) is described, Figs. 14 and 15 (not shown), whose arms (81), (82) are sufficiently resilient to provide a forward pushing action on the material of the filament as well as lateral compression against die (47) so that more material is available for the formation of the heads.

Title: Improvements in and relating to Strip Cutting and Affixing Apparatus
IPC: B65B61/06
Filed: 1968-07-29
Abstract: 1,192,852. Strip cutting and affixing apparatus. TETRA PAK A.B. 29 July, 1968 [7 Aug., 1967], No. 36095/68. Heading B8F. [Also in Divisions B4 and B5] A device for cutting pieces off a strip 13 and for affixing the cut-off pieces to a packaging material 41 by means of heat sealing comprises a fixed cutter blade 6 and a composite unit 17 consisting of a movable cutter blade 20, a contact heating unit 23 and a mechanism 29, 31 for transmitting motion to the cutter blade 20. The composite unit 17 is attached to a fixed frame 1 by means of a hinge 18. This allows, during the times when the apparatus is not in service, the composite units 17 to be moved away from, and to be returned to, the fixed cutter blade 6 without the position of the unit relative to the fixed cutter blade being thereby put out of adjustment. In operation, a web of packaging material 41 having holes provided therein over which pull tabs are to be affixed, is in a discontinuous manner fed forward together with a strip 13 so that a hole is caused to be situated beneath the strip 13. Hydraulic fluid is forced into the ram system 31 so that the piston 29 moves downwards. The movable cutter blade 20 slides along the leg 6<SP>1</SP> of the fixed cutter blade 6, after which the cutter blade cuts off the strip 13. The cut-off lengths of strip are then pressed by the base-plate 24 of the contact heating unit 23 against the packaging material 41, which is coated with a plastics material. The strip 13 is thus affixed with the aid of heat on to this in such a way that it covers the holes in the material. The movable cutter blade 20 and the contact heating unit 23 then return to the initial position as a result of hydraulic fluid being forced into the pressure hose 33. A suitable bearing pressure between the cutter blades is obtained with the aid of magnetic force or by a spiral spring arrangement. In order to render the blade retaining screws 8 and 27 readily accessible the composite unit 17 may be swung away from the frame 1 about the hinge 18. In a preferred embodiment two movable blades 20, 21 (Fig. 3, not shown) coact with fixed blades 6, (7) under the influence of magnets (39), (40) and the piston 29 is freely rotatable about a vertical axis, to ensure perfect register between the paired coacting blades. The hinge 18 may be replaced by a sliding rod arrangement which will allow the unit 17 to be completely removed from the frame 1.
