Title: Improvements in or relating to ball bearings
IPC: F16C43/08
Filed: 1922-07-27
Abstract: 205,896. Shorthouse, B. July 27, 1922. Ball bearings.-In a ball bearing for drawing. rollers of spinning frames &c., comprising one or more ball-races formed in a spindle or tube and two ball-retaining rings 9 each forming an outer race contained in a sleeve 8, the rings 9 are forcefitted one into each end of the sleeve 8 to confine one or more rows of balls between them and form a unit which cannot easily be dismantled. Additional means for securing the rings 9 may be provided. Each ring 9 is provided with a flange 10 which extends outside the balls to near the spindle or tube and serves to prevent distortion of the ring and to constitute a dust-excluding and oil-retaining device. In the form shown in Fig. 1, the spindle 5 is provided with two grooves 6 forming inner races for two rows of balls, and the bearing surface 15 of each ring 9 is cylindrical, the flanges 10 serving to position the bearing axially. Lubricant is supplied to the space 11 between the balls, as shown in Fig. 2, the surfaces 15 of the outer races are conical and the flanges do not touch the balls. The tangents at the points of contact with the inner and outer races are parallel. In Fig. 5, the tangents at the points of contact with the inner and outer races meet on the axis of the bearing, and a loose thrust ring 23 is located between the two rows of balls. According to the Provisional Specification, the tangents may meet at a point other than on the axis of the bearing, and the ring 23 may also serve as a cage for spacing the balls, being provided with projections engaging between the balls. Fig. 7 shows a bearing in which a single row of balls is confined between the two rings 9. For use with a wooden drawing roller, the periphery of the sleeve 8 is made polygonal and the roller is forced thereon. In the case of an iron roller, the sleeve 8 has a cylindrical periphery and is secured in the roller by a screw engaging a groove in the sleeve. Fig. 11 shows a cotton roller 32 in which the ends are bored to take the forced-in rings 9. According to the Provisional Specification, the bearing may be so constructed that it is self-aligning.

Title: The stabilization of synthetic linear polyamides against atmospheric degradation
IPC: C08K5/00
Filed: 1948-08-04
Abstract: A synthetic linear polyamide is stabilized against the degradative action of heat by incorporating into 1 million parts thereof, 10-500 parts by weight of a copper salt of an organic compound.  The copper compound may be added to the polyamide-forming reaction mixture. Copper salts mentioned are those of monocarboxylic acids particularly aliphatic monocarboxylic acids having 2-10 carbon atoms, and of b -diketones, e.g. acetyl acetone, diacetyl acetone, propionyl acetone and benzoyl acetone.  In example (1) polyhexamethylene adipamide flakes are coated with copper stearate, melted and extruded as filaments.  Example (2) employs polyhexamethylene sebacamide and cupric acetate.  Example (3) uses an interpolymer from hexamethylenediammonium adipate, hexamethylenediammonium sebacate and capolactam and stabilizes with copper stearate. Example (4) uses polyhexamethylene sebacamide and copper propionyl acetonate and Example (5) polyhexamethylene sebacamide and copper resinate.  In Example (6) aqueous hexamethylene diammonium sebacate is heated with acetic acid and cupric acetate to form a stabilized polyamide.  Other polyamides are also mentioned. Other materials, e.g. plasticizers, resins, waxes, fillers, pigments, or light stabilizers may be included in the compositions.  Specifications 461,236, 461,237 and 487,734 are referred to.

Filed: 1920-10-01
Abstract: 149,234. Evans, W. E., (Rohn, W.). Oct. 1, 1920. Cold and heat retaining chambers, vessels, and the like.-A vessel for storing or conveying liquefied gases, including hydrogen, consists of a plurality of hollow tapering shells with air-tight walls a, b; c, d; e, f; g, h, made of material such as metal or papier mÔchÚ and filled with gas and heat-insulating material such as feathers, cork dust, &c., the density of which is selected to produce the best insulating effect. Circulating spaces are left between the shells, and the liquefied gas that evaporates in the innermost vessel passes through the apertures k, l, m, and n to the atmosphere; small pipes o, p, q, and r, communicating with the interior of the shells, are provided through which gases such as hydrogen, nitrogen, nitric-oxide, and carbonic-acid respectively may be injected, these gases being such that their point of condensation is a little below the average temperature existing in the corresponding space. The thickness of the shells is so arranged that it differs at various points proportionally to the difference in temperature between the inner and cuter surface thereat. To vary the rate of evaporation, the gas instead of passing to the atmosphere through the aperture n is caused to pass through other tubes (not shown) which communicate with suitable parts of the circulating spaces.

Class 42 (1). [Also in Groups VI, VII and XI] Cushioning pads comprising essentially a film-like cover layer 1 and an initially separate substantially thicker foam cushioning layer 2 are heat-selaed at their margins. The layers are of polyvinyl plastic or polyurethane, including isocyanate plastics. Heat-sealing or seaming is effected by pressing the layers between a member 15, which may be an electrode plate or a buffer of insulating material such as a phenolic condensation product, and a backing plate and die 10, 10a, the latter having a knife edge 11 and a sloping face 12. A high-frequency charge which is passed between the electrodes concentrates the heating at the knife edge 11 and produce a decreasing sealing effect up the sloping face 12 so that a curvate marginal seam is produced. The heat-sealing may shape and partially sever the cushions and compress the cushion layer substantially.

Abstract: 1401904 Automatic tuning control; phase modulators HONEYWELL INFORMATION SYSTEMS Inc 3 May 1973 [4 May 1972] 21150/73 Headings H3A and H3R A voltage controlled phase shifter comprises a phase shifting network 7 including a plurality of voltage controlled variable capacitors 12-14 connected between a pair of input, output terminals 1, 16, a phase error detector 2 having inputs connected to the terminals 1, 16 and having its output connected to an integrator 4 for providing a control voltage for the capacitors 12-14. In operation, with suitable values of the inductances 9-11 and capacitors 12-14, the input and the phase shifted signals differ in phase by 90 degrees and any deviation from this phase difference is automatically corrected via the phase detector 2 and the integrator 4. By applying a control voltage Vc at terminal 18, controlled phase offsets of up to 30 degrees from the 90 degrees condition may be obtained. Thus the phase shifter may serve as a linear phase modulator with a peak deviation of 30 degrees. In Fig. 2 (not shown) three phase shifters are connected in tandem to provide phase shifts of 90, 180 and 270 degrees respectively.

Title: Process for the bonding together of two polyvinyl chloride surfaces

IPC: C09J5/02
Filed: 1969-04-25
Abstract: 1281823 Seaming non-metallic sheet material STAHLGRUBER OTTO GRUBER & CO 25 April 1969 [25 April 1968] 21292/69 Heading B5K A polyvinyl chloride surface having a completely dry coating of an adhesive is bonded to a second surface which is prepared by cleaning and/or roughening and coating with an adhesive in a moist condition by pressing the completely dry coating on the first surface on to the moist coating on the prepared surface. The polyvinyl chloride may be in the form of a woven fabric or may be reinforced by a fabric embedded therein. The invention is applicable to the on-site repair by patches of holes or tears in conveyer belts, footwear and polyvinyl chloride tiles for floor covering. The dry coating may be formed by first coating a sheet of silicone paper with the adhesive in a volatilizable carrier and, after evaporation of the carrier, detaching the dry adhesive layer from the silicone layer and transferring it to the polyvinyl chloride surface and joining it thereto by pressure at an elevated temperature by passage between heated rolls. Before passage between the rolls a protective covering foil, e.g. metal foil, may be placed on the free adhesive surface. This foil is detached before bonding together of the polyvinyl chloride surfaces. Alternatively, the cover foil may be first coated with the adhesive and joined to the polyvinyl chloride surface by pressure at an elevated temperature.
