A lockable slider for a sliding clasp fastener comprises a slider body 10 having formed therein an upwardly opening forward bore 1 and an upwardly opening rearward recess 2 in communication with each other, a cylindrical cam element 5 rotatably received in the bore having a slanted annular cam face 18 at its inner end and a key hole 8 in its upper portion, a cover plate 3 closing the bore and provided with a key hole 6 in registration with the key hole 8, the cover plate also closing the recess 2, a lever member 12 pivotally mounted in the recess 2 with its forward end in engagement with the cam face 18, resilient means for biasing the rearward end of the member 12 downwardly, and a locking pawl member 13 formed on the rearward end of the member 12 for co-operation with the fastener chains of the sliding clasp fastener when the rearward end of the member 12 has been moved to the downward limit of its movement in which position the forward end of the member 12 is held in engagement with the lowest point 18<SP>2</SP> of the cam face 18 by force of the resilient means. As shown the resilient means comprises a U-shaped leaf spring 15, and the lever 12 is pivoted on a pin 14 received in grooves 19 is the walls of the slider body. Ribs 9 on the cover plate and co-operating grooves 7 in the cam element 5 formed on diametrically opposite sides of the key holes 6 and 8 are urged into engagement by a spring 11 to prevent accidental rotation of the element 5 from the locking or releasing position. In other embodiments the resilient means is a plate spring integral with the cover plate or the lever member and the pivot means is provided by a co-operating rib and recess on the lever member and in the slider body or vice versa.

Abstract: 983,834. Typewriters; feeding webs; stopping arrangements. LAMSON PARAGON Ltd. Nov. 8, 1962 [Nov. 9, 1961], No. 40154/61. Headings B6B and B6F. An aperture - sensing mechanism in a typewriter for feeding continuous stationary web between successive lines of typing, comprises an apertured endless tape 30, Fig. 1, which is advanced about a roller 29, Fig. 3, and drum 12 by rotation of a handle 8, so that a sensing pin 20 urged under spring action may pass through a sensing aperture in the tape to engage a hole 14 in the drum 12 to thereby arrest the tape. Downward swing of the handle 8 (position shown chain-dotted) causes a sleeve 11 in the drum 12 to pivot a lever 17 anticlockwise to urge the sensing pin 20 into contact with the sensing tape 30, whereby rotation of the handle brings into operation a pair of pinwheels 4 to advance the continuous web around a platen 2 (Fig. 2, not shown), the feed movement being arrested when the said pin 20 engages one of the holes 14. Feed movement of the web is assisted by a pair of infeed and outfeed guides 31, 32, respectively. Sensing tapes with varying programmes and of varying lengths may be used by vertical adjustment of the roller 29 supported on a sleeve 27 carried on a post 23. Specification 983,835 is referred to.

Patent GB-1104822-A (GB)
Title: Polymer treatment
IPC: C08G2/00
Filed: 1965-09-22
Abstract: A solid polymer containing oxymethylene groups and groups of greater stability to alkaline hydrolysis is subjected in solid particulate form to treatment with water and/or an organic hydroxy compound at a temperature high enough to cause degradation of terminal oxymethylene groups but too low to cause the polymer particles to become tacky enough for them to agglomerate, the treatment being effected while a mixture of the polymer particles and liquid reagent is being forwarded without back-mixing.  The polymer may contain 85-99.9 mole per cent oxymethylene and 0.1 to 15 mole per cent oxyethylene groups e.g. those derived from cyclic ethers-a third monomer may also be present and the polymer may be end-capped.  The liquid reagent is preferably aqueous.  The water may be replaced wholly or in part by a liquid organic water-soluble compound having an oxygen atom directly bonded to a carbon atom e.g. ketones, esters and ethers, or such a compound may be used together with the organic hydroxy compound. The polymer is preferably treated under alkaline conditions i.e. in the presence of a strongly basic hydroxide, a salt of a strong base and weak acid or ammonia or an organic base. The polymer may be ground with reagent liquid to form a slurry and the slurry diluted and heated to the desired stabilization temperature after which it may be concentrated and then forwarded through a zone in which at least the major part of the stabilization takes place.

Abstract: 928,630. Repairing cables. STANDARD TELEPHONES & CABLES Ltd. Nov. 17, 1961, No. 41249/61. Class 36. [Also in Group V] A method of sealing an interruption in a thermoplastic covering of a cable includes the steps of placing a thermoplastic patch in contact with the covering at the region of interruption, placing the assembly in a mould and heating that portion of the mould in contact with the patch in order to fuse the patch and covering- together. As shown, a U-shaped mould 5 of asbestos compound has, incorporated in it and flush with the moulding surface, a heating element 6 which may be a strip if the interruption to be sealed is longitudinal. Alternatively (Fig. 3, not shown) a cartridge heater 22 inside a metal sleeve 19 probed through the mould may be used if the interruption is a hole in the covering, the hole being plugged with a similar material as the covering before patching it up.

Abstract: 1,205,603. Braking rollers for roller conveyers. E. LAGEMANN. 12 Sept., 1967, No. 41474/67. Heading B8A. [Also in Division F2] A braking roller for a roller conveyer includes a gear pump 17, 18 of which chambers on the pressure side and on the suction side are connected only by clearances between the gears 17, 18, and by clearances between the gears and walls of the pump casing 8, 10. The gear 18 is secured on a shaft 19 which is driven, via a pinion 20, by a ring gear 13 non-rotatably mounted on a stub axle 6. The shell 1 of the roller is supported on bearings 4, 5 and is secured to the pump casing 8. A bearing 14, 15 is provided between the ring gear 13 and the casing 8. Rotation of the roller produces a planetary action of the pinion 20 to drive the pump gear 18. In a modification, Fig. 2, the pressure and suction sides of a pump 42, 43 are connected by channels 40 of which the bore is adjustable by a screw 41 for varying the braking torque. The channels may have exchangeable jets for adjustment of the braking effect. For limiting the torque, there is provided a friction coupling 29 which may also have means for delaying engagement of the coupling. Such provision results in improved starting up characteristics of heavily loaded rollers. In addition to or as an alternative to the friction coupling a dog coupling may be provided, Fig. 4 (not shown). A freewheel coupling, Fig. 5 (not shown), permits pushing back of a load without any braking. An outer shell 23 for the roller 22 enables material which has been heated to high temperatures to be conveyed. Air flow is aided by perforations 26. There may be separate reservoirs for the pressure medium and the pressure produced may be used to operate the friction coupling hydraulically.

Abstract: 1319393 Ball joints C S WHITE 6 Sept 1971 [28 Sept 1970] 41477/71 Heading E2F [Also in Division F2] A bearing is made by applying a thin layer 13 of metal onto the surface of a bearing element e.g. a ball 11, so that there is substantially no adhesion therebetween, plating a layer of bearing material onto the thin layer and building up a housing 21 bonded to the bearing material. The thin layer is erodable so as to provide the required bearing clearance between the bearing element and the layer of bearing material. A discontinuous layer 17 of solid lubricant e.g. graphite may be applied between the thin layer and bearing material so as to be exposed on erosion of the thin layer. The thin layer may be of lead or tin and the bearing material may be silver, nickel or bronze. The housing may be of iron or nickel and may be plated or sprayed onto the bearing material. Instead of wearing away the thin layer, the bearing may be heated to melt the layer.
