Filed: 1916-02-07
Abstract: 100,070. Ames. E. U. Feb. 9, 1915, [Convention date]. Circular machines, latch-needle, particularly for hosiery. A rotary needle cylinder 2 is secured within a ring 5, Fig. 5, by screws 6 and is driven through change-motion gearing of the kind described in Specification 11684/15, [Class 80 (ii), Gearing, Variable-speed &c.]. Splicing-yarn is supplied as described in Specification 102,736 by a finger 48, Fig. 3, rendered operative by a spring mounting 133 and controlled by a cam 52<f> on the drum 37 acting through an arm 52<e>, lever 52, and jack 42<b>. For sole and like splicing, the finger 48 is rendered alternatively operative and inoperative in each course by a cam 142 beneath the needle cylinder engaging a roller 141 on a lever 140 connected by a link 136 to the arm 52<e>. The sinker cam-ring 18 which is moved frictionally by the cylinder, carries a pivoted cam 19, Fig. 7, having a depending arm 21 adapted to engage adjustable stops 22, 23. The cam 19 comprises end portions 19<a>, 19<b> and a straight portion 19<c>. Instead of the pivoted cam 19, the ring 18 may be provided with any suitable cam, for example a straight fixed cam. As shown in Fig. 5, the sinkers 15 are pivoted at 14 and are furnished with tails 17 adapted to be depressed by the cam 19 against the action of a spring clasp ring 16. To avoid straining the yarn in splicing, the loops of the spliced portion are increased by moving the sinker ring 18 relatively to the needle cams 64, 65, 66, 67, Fig. 7, in a direction opposite to that of the motion of the cylinder. The movement of the sinker cam-ring is effected by a lever 146 provided with an adjustable screw 147, engaging a lug 148 on the ring 18 and controlled by a spring 149 and an arm 144 carrying a roller 145 engaging the cam 142. When the splicing operation is arrested by the cam 52f engaging the arm 52<e>, the lever 146 is also thrown out of action by the lever 140 engaging an adjustable screw 151 on the arm 144. The Specification as open to inspection under Sect. 91 (3) (a) comprises also the subject-matter of Specifications 102,736 and 102,737. This sub. ject-matter does not appear in the Specification as accepted.

Abstract: 304,659. Bakelite Corporation, (Assignees of Bender, H. L.). Nov. 11, 1926, [Convention date]. Divided on 280,521. Condensation products of phenols with formaldehyde and aniline or its homologues.-Resinous products are obtained by condensing a phenol with formaldehyde and aniline (or a homologue) in the presence of a basic catalyst, and expelling aniline from the condensation 'product; the aniline is preferably expelled by distillation under reduced pressure. According to the conditions, the products may be potentially reactive, i.e. convertible by heat into infusible and insoluble bodies, or they may be slowly reactive or non- reactive products convertible by addition of a methylene-containing hardening agent into potentially reactive products. In an example, phenol (5.3 mols.), aniline (2.7 mols), formaldehyde (10 mols.) and a little hexamethylenetetramine are heated together first under reflux and then so as to allow water and part of the aniline to escape; instead of hexamethylenetetramine other basic substances, such as sodium carbonate or calcium hydroxide, may be used. A filling material may be added prior to the expulsion of the aniline, and the expelled aniline may be re-used. The Specification as open to inspection under Sect. 91 (3) (a) describes the manufacture of like products by condensing a phenol with formaldehyde and aniline (or a homologue) substantially in the molecular proportions 2, more than 2, and 1 respectively, and expelling aniline from the condensation product. Reference is made also to the manufacture of a resin by the reaction of phenol with anhydroformaldehyde aniline and hexamethylenetetramine.

Abstract: 1,273,691. Fusion welding. LA SOUDURE ELECTRIQUE AUTOGENE PROCEDES ARCOS, S.A. 16 Jan., 1970 [6 Feb., 1969], No. 2267/70. Heading B3R.  A process of overlaying e.g. hard-facing, a metal workpiece comprises coating the workpiece with a material capable of forming a barrier layer to inhibit dilution of the facing metal by the base metal, and finally applying the facing metal by an electric arc or plasma torch device, this step being accompanied by melting (or remelting) of the material forming the barrier layer. Materials referred to as barrier layers include cobalt, chromium, tungsten, molybdenum, the carbides of chromium, tungsten and molybdenum, zirconium oxide and titanium oxide. Methods of application of the barrier layer include flame spraying, plasma spraying, electroplating or application as an emulsion, containing possibly also a binder and adhesive. The overlay metals include those known under the Registered Trade Marks Stellite and Inconel as well as stainless steel. The facing metals may be applied by a series arc procesi in which the arc is struck between two consumable electrodes 3, 4 arranged symmetrically to the plane of the workpiece. Alternatively one of the electrodes may be of graphite or tungsten, in the latter case optionally thoriated or zirconated and with argon shielding. Where the barrier layer is of one of the oxides mentioned the arc may be struck by a high-frequency discharge. In an example a powdered alloy of 1% Carbon, 28% Chromium, 5% Tungsten and the balance Cobalt was applied by plasma spraying under a nitrogen atmosphere and a hard-facing layer applied using electrodes of the following composition:1% Carbon, 31% Chromium, 5À5% Tungsten, balance Cobalt.
