Title: Improvements in guiding devices for the winding of thread, wire, rope, chain or the like
IPC: B65H57/00
Filed: 1937-05-05
Abstract: 483,356. Winding thread &c. DECOMBE, G. May 5, 1937, No. 12843. [Class 120 (ii)] A guiding-device for winding thread, wire, rope, chain, and the like on to spools or bobbins comprises a member mounted on an arm displaceable relatively to the spool for guiding the wire &c. directly onto the spool and having a heel part adapted to bear on the spool or a layer of wire &c. wound thereon and to be engaged laterally .by the turn just wound, the movement between the guide member and spool being caused solely as the result of such lateral engagement and the rotation of the spool; the wire &c. is suitably tensioned and passes through the guide member so as to be guided thereby directly on to the spool at a point adjacent the previous turn. As shown, the guide member g is formed as a spout at the end of the arm a with a heel part h which is held in contact with the underlying layer d on the spool e by the tension of the wire b which passes to the member g over a number of pulleys i freely slidable along rods j in a support n also carrying the rod k to which the arm a is fixed; the rod k is rotatable and slidable in the support n, is braked by springs o and may be curved so that the guide member at the end of its traverse is not prevented from contacting with the flanges of deformed spools. The spout may be replaced by a roller at the end of the arm a, the lower rim of the roller constituting the heel part of the guide member or the spout and arm may be replaced by a roller of large diameter rotatable and slidable on the rod k which is then carried by pivoted arms. In another form, the arm a is attached to a forked member freely rotatable on a sleeve loosely mounted on a curved bar carried by the support n and the sleeve carries a pulley around which the wire is led to the spout at the end of the arm. In a further form, the arm a is mounted frictionally by a pivot in a frame pivoted in the support n, the arm oscillating about the pivot which is disposed at right-angles to the pivoted frame; the wire is led to the spout around a pulley slidable along a bar fixed in the support. For winding large wires or cables or covered cables the guide member takes the form of a grooved pulley at the end of the arm and the heel is formed by a roller with rounded edges pivoted in the arm. In another arrangement, the arm carrying the spout is pivoted but does not slide and the spool is arranged to move in the direction of its axis. Flangeless spools may be wound by controlling the relative sliding movement between the guide member and spool by stops and the sliding bar k may be replaced by a small flexible chain mounted on rollers.

Title: Improvements in compositions for the formation of wear-resistant accurate surfaces
IPC: C04B35/63
Filed: 1947-05-14
Abstract: Articles having hard wear-resistant accurate surfaces, particularly surface-plates for use in gauging, are formed from abrasive particles having a hardness above 9 on Moh's scale bonded with a vi'rified bond and having each particle on the usable surface smoothed so as to render it non-abrasive.  The abrasive may be fused alumina, sapphire, ruby, corundum, emery, or silicon, tungsten, tantalum, titanium, boran or other carbide, or boron, titanium, or other nitride.  The bond may be a ceramic material such as clay or a mixture of clays, oxides, or silicates, a glassy or porcelain frit, or mixtures thereof.  The powdered abrasive and bond are thoroughly mixed, pressed, dried, and fired. The product is then ground preferably with a metal-bonded diamond wheel set so as slightly to dish the article, and is subsequently lapped against a similar product in a series of operations using, preferably, diamond grit of decreasing sizes, and is finally lapped without any grit, using gasoline as a lubricant. The grinding and lapping are preferably effected in a machine wherein the product is rotated and its surface is traversed by a grinding-wheel.  Specification 563,652 is referred to.

Title: Filling containers with measured contents
IPC: G01F11/02
Filed: 1929-04-29
Abstract: 328,789. Lamb, H., and Fee, T. A. April 29, 1929. Fixed - chamber apparatus.-Measured quantities of lard &c. are delivered from opposite ends of a cylinder 16 within which a piston 17 reciprocates under the control of a five-way valve 21. Material is supplied by way of a pipe 22 to the port 30 and is'transferred by the valve passage 36 to the passages 19, 20 alternately and thence to the corresponding end of the cylinder 16. Duplicate upwardlydirected discharge pipes 25, 26 are alternately supplied by way of the valve passage 37. Electrical or fluid pressure means effects automatic reversal of the valve. The valve lever 39 may be connected to an armature 41 oppositely acted on by windings 40, 103 when these are energized by the closing of contacts carried by the piston rod 18. The contacts are kept apart by springs until adjustable abutments 45, 46 are encountered.

Abstract: 1435294 Excavator buckets; rippers D G LUCK 2 April 1975 [3 April 1974] 13479/75 Headings E1F and E1G A ripper-excavator bucket assembly for mounting on the boom or dipper stick of an hydraulically-operated excavator comprises a ripper 1 having a bucket 2 pivotally supported thereon and means for moving the bucket relatively to the ripper between a non-operative position of the bucket in which the bucket does not impede the functioning of the ripper to an operative position of the bucket in which the bucket is supported on the ripper. The bucket is centrally slotted to enable the outer end of the ripper and the control piston rod of the ripper to pass through the bucket during pivotal movement of the bucket, which movement is controlled by a linkage system and a hydraulic piston cylinder assembly extending between the dipper stick and the bucket. When the bucket is swung from its inoperative position behind the ripper to its operative position the working face of the ripper forms part of the inner, outward facing surface of the bucket. The pivot bearing formed in the ripper for the pivot means of the bucket is elongated so that the bucket may have a limited movement due to the configuration of its actuating linkage along the length of the ripper as it is pivoted relative to the ripper so that the bucket may be supported by the toe of the ripper when the bucket is in its operative position.

Abstract: 761,694. Moulding-processes. GENERAL MOTORS CORPORATION. May 10, 1954 [May 28, 1956], No. 13502/54. Class 83 (1). In a shell-moulding method, a layer of mix containing 1-4 per cent by weight of a thermosetting synthetic resin is applied to a heated pattern or core-box, and pressure is then exerted on the layer before or during curing thereof, by a die having a profile the reverse of that of the pattern or core-box. Mould-mix is blown from a container 20 on to a pattern 10, 11, electrically heated by resistance-elements 12 to a temperature of 350-400‹ F. The partially-cured shell is then pressed and cured by a die 30 heated by resistance-elements to a temperature of 300- 1500‹ F. The pressure is of the order 25-2000 lb. per square inch, and preferably is sufficient to reduce the thickness of the shell 20-25 per cent. The die may be shaped so as to press some parts of the shell more than others to strengthen certain parts. Alternatively, the layer of mix may be applied to the pattern by dumping.

Title: Improvements in or relating to the drier drums of paper-making machines
IPC: D21F5/02
Filed: 1960-04-14
Abstract: 955,468. Rollers. KIMBERLEY-CLARK CORPORATION. April 14, 1960 [April 15, 1959], No. 13525/60. Heading F2U. [Also in Divisions D2 and F4] A drier drum for a paper-making machine comprises a generally cylindrical shell, and an inlet and an outlet for the supply and withdrawal of heating fluid to and from its interior. The shell has a diameter of several feet and a length of several feet and is crowned so that its diameter progressively decreases along a very gradual curve by a small fraction of an inch on each side of its centre line up to points (d1, Fig. 6) about twenty inches inwards from the ends, then continues to decrease progressively along a continuation of the curve by a greater fraction of an inch from those points to further points (d2) about six inches inwards from the ends, and thereafter decreases progressively by a still greater fraction of an inch over the last six inches at each end. The shell may be a single casting, e.g. of cast iron, or made from plates, e.g. of aluminium-bronze, welded together as shown in Fig. 4. As shown in Fig. 3, the ends of this shell are closed by heads 15 and mounted on a hollow shaft 16, fitted with steam nozzles directed towards the inner surface of the shell and scoops collecting condensate and discharging it through the shaft. The shell may be crowned by grinding it under actual or simulated service conditions; i.e. by applying steam under pressure to the interior of the drum, and a cooling medium to that part of the drum that is covered by the wet paper web in service. This cooling may be effected by winding a strip of open-mesh cloth over the central portion of the drum and spraying water on to the cloth. The end portions, not covered by the cloth, are then ground, e.g. by an abrasive belt. The result of this crowning is that when the drum is in use, and its end portions are heated by steam to a higher temperature than that of the central portions cooled by the wet web upon it, the diameter of the end is, as shown by curve C in Fig. 6, no greater than that of the central portion and wear on these ends is therefore reduced. Specification 634,245 is referred to.

Title: Improvements in insecticidal preparations
IPC: A01N25/04
Filed: 1943-08-20
Abstract: The oil phase of an insecticidal oil and water emulsion consists of heavy coal tar naptha (boiling at about 150-190 DEG C) or a mixture of heavy coal tar naptha and a mineral oil, with an additional contact insecticide dissolved therein.  The additional insecticide may consist of pyrethrins, rotenon, nicotine, an organic e.g. alkyl, thioacynate or p-dichloro-diphenyltrichlorethane.  Kerosene is a suitable mineral oil.  An emulsifying agent may be added and this may consist of an oil-soluble component, e.g. cholesterol, cetyl alcohol, oleyl alcohol, a commercial preparation of mixed secondary alcohols C10-C18, geranium oils or essential oils containing alcohols, and a water soluble component, e.g., sodium cetyl sulphate, sodium oleyl sulphate, hexadecyltrimethyl ammonium bromide, or hexadecyl pyridinium bromide.  Alternatively a composite emulsifying agent such as a sulphuric ester of a long chain secondary alcohol, or a long chain ester of glycerine or a glycol may be used.  Hydroquinone may also be an ingredient of the composition as an antioxilant for the pyrethrins.  The Provisional Specification describes also the employment in an oil and water emulsion of compounds which act as fumigants, such as xylene, mesitylene, pseudocumene, indene, coumarone and cresylic acids, instead of the heavy coal tar naptha. Specifications 280,256, [Class 81 (i)], 426,450, 443,023, 547,927, 568,009, 568,011, and 569,429 are referred to.
