Abstract: 1,206,813. Releasable fastenings. F. T. PRODUCTS Ltd. 26 Jan., 1968, No. 4174/68. Heading E2B. [Also in Division F2] A clip for attachment on a rod or similar elongate article comprises a plate 11 formed with a shallow channel 14 extending transversely there across and a pair of tongues 15, 16 struck from the plate and extending upwardly from opposite sides of the channel wherein the free ends of the tongues define an aperture through which the rod or similar article can be forced in one direction only and wherein the portions of the plate in the channel adjacent the tongues are bent upwardly in the same sense as the tongues to form lugs 21, 22. As shown the clip is used for attaching a pair of cables 23, 24 to support the clip having downwardly curved end portions 12, 13. A tool for releasing the clip from the rod or similar elongate article comprises a pair of pivotal arms the jaws 27, 28 of which have similar inturned end portions 29, 30, each end portion being adapted for insertion between the respective one of the said lugs of the clip and the tongues to force the tongues upwardly and out of engagement with the rod or similar article when the jaws are closed the outer surface of each end portion remote from the pivot point of the arms being stepped to provide an inclined cam face 35, 36 which extends across the full width of the end portion and co-operates with a respective said lug of the clip when the feet are inserted between the lugs and the tongues and forced inwardly.

Title: Sheet feeding mechanism for typewriters or like machines
IPC: B41J13/042
Filed: 1955-02-11
Abstract: 767,373. Sheet feeding mechanism for typewriters &c. ROYAL McBEE CORPORATION. Feb. 11, 1955 [March 29, 1954], No. 4197/55. Class 100(4) A typewriter comprises a platen or work-sheet feeding cylinder A journaled on end plates 1, 2 of a carriage or support frame B, a rear work-sheet introductory-feed-roll 6, mounted for rotation about an axis parallel to that of cylinder A and spaced therefrom so that worksheet material introduced between them is gripped, and work-sheet-propelling rollers 7, 8, 9 all journaled for rotation about an axis parallel to that of cylinder A and circumferentially displaced in the direction of sheet feeding with respect to the cylinder A from the rollers 6. The relative frictional sheet feeding characteristics of the rollers 7, 8, 9 and roller 6 are such that the sheet feeding tendency of the rollers 7, 8, 9 is greater than that of the roller 6. The work-sheet material is consequently gripped with more pressure between cylinder A and roller 6 than between rollers 7, 8, 9 and the cylinder. For this purpose the roller 6 may be formed of relatively hard material such as polished aluminium, having a Rockwell B scale hardness of 66- 68, and the propelling rollers 7, 8 and 9 are of soft resilient rubber having a Durometer hardness with 40-50 and a high coefficient of friction. The roller 6 is pressed against cylinder A by springs 30, 31 acting on rear edges of arms 24, 25 in which shaft 23 of the roll is supported. This pressure may be adjusted by nuts 32 on bolts 33, 34, and may be in the range of 1 to 1¢ lbs. The front pressure feed rollers 7, 8 and 9 are pressed against the work by separate independently adjustable mechanisms E of known kind which act on arms 59, 60, 61 and press feed rolls 7, 8, 9 against the work-sheet material between these rolls and sheet feeding cylinder A. Top or bail rolls 15 formed of the same material as the rolls 7, 8, 9 may be carried by a bail 16 pivoted on the end plates 1, 2 to assist in holding the worksheets against the cylinder A.
Patent GB-634445-A (GB)
Title: Improvements in method and apparatus for moulding tubing
IPC: B29C48/90
Filed: 1947-02-13
Abstract: 634,445. Extruding thermoplastic tubing. BAKELITE CORPORATION. Feb. 13, 1947, No. 4211. Convention date, Feb. 16, 1946. [Class 87 (ii)] Extruded thermoplastic tubing is shaped by forcing it, while still hot from the extrusion nozzle, into contact with the inner surface of a moulding and cooling die by internal gas pressure. The inner surface of the die is made slightly rough, to prevent sticking of the tube during its passage therethrough. A gas which may be air, nitrogen or hydrogen is brought into contact with the outer surface of the tubing before it is introduced into the moulding and cooling die and during at least part of its travel through the die. The slightly rough surface of the die is formed by etching, by mechanically abrading a polished die surface or by pressing metal powders into the required shape and then sintering the powders. The sintered die may be impregnated with oil. In one form of apparatus, thermoplastic material is forced between a die 12, provided with electric heaters 14, and a mandrel 11. The extruded tube passes through a chamber formed by a bushing 21 and then through the die 20. Compressed air is supplied through pipes 31, 30 to inflate the tube, and is also supplied to the outer surface of the tube through pipes 32, 36, a chamber 37, and, to provide an even distribution of the air, through spaced holes in a ring 38. In a modification, the air may be supplied to the outer surface of the tube by directing it in one or more streams against selected peripheral portions of the tube to produce, owing to the localised cooling effect of the air, a tube having longitudinal ridges. The air around the tube is allowed to escape through a pipe 42. The internal and external air pressures are balanced by a valve 43. During the starting-up of the process, until the tube expands against the moulding and cooling die 20, temporary cooling means are used. When the tube emerges from the die 20, the end is clamped, to maintain air pressure in the tube, and the tube led over a conveyer 44, Fig. 2, and between rollers 46, 47, 48. After the clamped end has left the roller 48, a second clamp is applied between the die 20 and the conveyer 44, the first clamp is released, to allow sufficient water to enter the tube to form a liquid seal 50, and the second clamp is then released. The tube may then be cut beyond the roller 48 without loss of pressure. To prevent blow-outs or loss of the liquid seal due to sudden surges of internal pressure, a safety valve 51 is provided. In another form of apparatus, (Fig. 4 not shown), the tube is extruded into the flared mouth of a cooling die and air at atmospheric pressure contacts the outer surface of the tube, and is drawn into the die. When using thermoplastic materials which have a large shrinkage on cooling, the die 20 may taper, to maintain contact with the tubing. The air in contact with the outer surface of the tubing may be heated to provide an extra glossy finish.

Abstract: 872,693. Cutting-tools. WILLIAMS, T. V. Feb. 8, 1960, No. 4339/60. Class 83 (3). Each bit 28, Fig. 4, of a milling cutter, lathe tool &c. having a number of cutting-edges, is indexed in a tapered recess 27 in the tool body 26, by an indexer 29 which has a projection 32 engaging a hole in the bit, the hole having the same shape as the cutting edges.

In a modification, Figs. 6 and 7, an L- shaped member 41 is interposed between the indexer 36 and the wedge 37, the screws 38 engaging one leg of the L-shaped member, and the indexer is adjustable on wedges 42. In further modifications the indexer is adjusted by screws or pins engaging the base and end of the recess in the tool body, or the projection on the indexer may be bifurcated so as to be expanded in the bit by a screw, or the projection may be separate and not integral with the indexer.

The reading head 10 is moved to provide line scanning of the document, the document being stepped to provide the frame scanning. Lamp 15, which may self-focussing, and photodetector 16 are removably mounted in head 10. The ends of the fibre optics bundles at 18c transmitting light to and receiving light from lens system 12 may be interleaved; alternatively these ends of the fibre optics bundles 18a, 18b may be side by side and adjacent a fibre optics light integrating rod (19, Fig. 1, not shown), which transmits light to and from lens system 12 via a diaphragm (20). In an alternative embodiment, these ends of the fibre optics bundles are partly interleaved, the central region, perpendicular to the line-scanning direction, of the portion 18c being formed by interleaved fibres from the two bundles, the side regions of portion 18c being formed by fibres from the respective bundles 18a, 18b. In this case a rectangular aperture (22, Fig. 3, not shown), having its major dimension perpendicular to the line-scanning direction may be associated with the lens system 12; at least the central (interleaved) region of portion 18c may then have its dimension parallel to the line-scanning direction increased relative to its dimension perpendicular to the line-scanning direction.
