Abstract: 229,538. Sokal, S., (Adrian & Busch). Dec. 13, 1923. Sewing-machines; lock stitching by hooks.-A take-up arm 34, Fig. 9, specially suitable for a hook-needle sole-sewing machine is oscillated (so t'hat its free end A moves steadily in one direction to deliver the thread for the formation of the loop and rapidly in the opposite direction to take up slack), by mechanism comprising a link 37, a radius arm 44, and a link 43 pivoted at the pivot point XXVI of the members 37, 44, and connected at XXV to the extension 42 of a member 40 of a four-bar linkage driven by a rotating member 38. By this arrangement the pivot XXV of the link 43 is caused to move in a closed curve and the pivot XXVI along the arc of a circle. Small movements along the line x<1>, y<1> forming part of this closed curve cause large movements along the arcuate line x<11>, y<11>. The rotating member 38 may be an eccentric disc 38, Fig. 6, the member 40, 42 being constituted by the strap 39 having extensions 40, 42.

Title: Improvements in and relating to magnetic alloys
IPC: C22C38/34
Filed: 1927-05-13
Abstract: 295,443. Marks, E. C. R., (Bakelite Corporation). May 13, 1927. Phenol-formaldehyde condensation products. - Resinous products are, obtained by condensing dihydroxydiphenylethane, or a phenolic mixture which includes dihydrosydipbenyletbane, at an elevated temperature with paraformaldehyde, hexamethylenetetramine, or other methylene. containing hardening agent. The products have the general properties and uses of resins of the phenol-formaldehyde type. In one example, dihydroxydiphenylethane and paraformaldehyde are heated together at 180-200‹ C. to produce a fusible resin which may be mixed with a further quantity of paraformaldehyde, with or without a filler, and heated, preferably under pressure, to produce an infusible mass. For example, a mixture of resin and filler may be heated in a hydraulic press to a temperature of 100‹ C. or more under a pressure of 2000 lb., cr the resin alone may be heated in a closed vessel to a temperature not much above 100‹ C. under a pressure of 80 lb. In another example, hexamethylenetetramine is used instead of paraformaldehyde, and in a further example the amount of paraformaldehyde or hexamethylenetetramine is increased so that an infusible product is obtained in one operation.

Filed: 1922-05-08
Abstract: 190,413. Aspelin, J. O. May 8, 1922. Fish-hooks; automatic striking- apparatus. - The points of a twohook fish-hook in their inoperative position lie one over the other with their points more or less protected but spring apart when grasped by a fish. The hooks 15, 16 are attached to plates 6, 7 which are loosely pivoted on a pin 8 and are separated by a washer around the pin. The plates are connected to the ends of a coil spring 14 which tends to draw the parts 12 together but is prevented by a pin 11 on one plate 7 engaging a shoulder on the other plate 6. A fish taking the bait rocks the plates about the washer on the pin 8 as a fulcrum and releases the pin 11 to allow the spring 14 to spread the hooks. The line 19 may be attached directly or by a swivel to the loop of the spring 14. Wings 17, 18 may be formed on the plates to cause the hook to spin.

Abstract: 477,829. Colour photography. MILLS, T. A., FOX, J. W., and KENT, F. W. June 5, 1936, No. 13050. [Class 98 (ii)] In copying multicolour screen photographic or kinematographic images on to multicolour screen material, part of the exposure is made direct on to the emulsion to produce a sharp black-and-white or monochromatic key image and part is made throughout the transparent support to produce diffused images of the colour-component records. The key image may be produced by making an intermediate black-and-white or monochromatic negative of the original multicolour screen record on to panchromatic material, and printing this on to the emulsion side of the multicolour screen copy material. Alternatively, an ordinary positive emulsion for the reception of the key image may be coated on the copy material before or after processing the colour records. If the copy material is to be processed to a positive by the reversal method, positives are used in the printing. If a negative original is used the key negative is produced by the reversal method or otherwise. If line-screen material is employed, moirÚ may be prevented by arranging the lines on the copy at an angle to those on the original. Specification 434,434 is referred to in the Provisional Specification.

Abstract: A composition which can be used to seal articles against the intrusion of water, is mechanically and chemically stable up to 220 DEG  F., is a non-conductor of electricity, is easily mouldable by the hand, and is readily adhesive to wood, plastics, fabrics and metal even when contaminated with oil or grease, consists of 10-35 per cent by weight of dehydrated asbestos or other fibre which resists a temperature of 220 DEG  F., 25-55 per cent of a petroleum oil having a viscosity between 100 seconds Redwood I at 100 DEG  F. and 180 seconds at 210 DEG  F., and 10-40 per cent of a water-insoluble soap.  Rock wool or cotton linters may be substituted for asbestos, and dehydration, so that they contain not more than 0.1 per cent water, is effected by heating to at least 220 DEG  F. and preferably to 290-320 DEG  F. at atmospheric or reduced pressure. Preferably the viscosity of the oil is between 200 and 500 seconds at 100 DEG  F.  The soaps are the salts of lithium, polyvalent metals such as aluminium, zinc, cadmium or, preferably, magnesium, calcium, or barium, with fatty acids having 12-20 carbon atoms in the molecule, and are preferably free from glycerine.  Wool grease stearine is preferably included. The composition is made by mixing the fatty acids with a part of the oil and asbestos, heating to dehydrate the asbestos, cooling, adding the necessary base to form the soap and the remainder of the oil, and stirring.  According to an example, 26 parts of a petroleum oil are stirred with 13.5 parts of wool grease stearine, 21 parts of distilled fatty acids, and 22.5 parts of asbestos while heating to 275 DEG  F., the mixture is cooled and 4.3 parts of calcium hydroxide suspended in 12.7 parts of the oil are stirred in.
