Title: Improvements in or relating to flexible couplings
IPC: F16D3/76
Filed: 1930-12-23
Abstract: 368,876. Universal joints. BUDD WHEEL CO., 2500, Hunting Park Avenue, Philadelphia, U.S.A.-(Assignees of Rosenberg, R. H. ; c/o Budd Wheel Co., 12141, Charlevoix Avenue, Detroit, Michigan, U.S.A.) Dec. 23, 1930, No. 38703. Con. vention date, Jan. 30. [Class 80 (ii).] In a flexible coupling comprising an inner member 2 and an outer member 4 with an interposed rubber sleeve 3 exerting a high radial pressure on the torque transmitting surfaces as a result of deformation due to axial mass tension, at least one of the torque transmitting surfaces, the inner 2, is convex throughout its entire working length. The outer member 4 is curved complementary to the inner member. In one form raw rubber is packed in the space between the members and vulcanized thereto, the surface bond being then a combination of adhesion and friction due to the compression. In the form shown in Figs. 1 and 6, a rubber ring R, after being greased, is drawn over one side of the member 2 by use of a pilot cone N, Fig. 6, screwed to the driving shaft and afterwards removed. A flanged locking ring F, forming part of the outer surface, and initially flared outwards, as shown dotted, is then sprung into a groove in the member 4. The spring locking flange may be replaced by a separate collar screwed in the member 4. The metal parts may be of drawn or swaged tubing or of stampings in halves flash-welded together. In a simpler form, the driving shaft 1 carries a solid partspherical coupling-block coacting with a single internally spherical block bolted to a flange on the driven shaft. The rubber ring is placed within the driven block and is pulled over the driving block by use of a pilot cone, the rubber spreading evenly between the surfaces. Any or all of the torque transmitting surfaces of the rubber or ball-and-socket members may be annularly or axially discontinuous, and may be roughened or shallowly contoured to increase the bonding area. Several couplings, four shown, may be used in series. The joint gives uniform angular velocity and may permit a relative rotary movement between the shafts of a right-angle and a range of angular movement of half a right-angle. The Specification as open to inspection under Sect. 91 (3) (a) states also that the ball and socket members may be cylindrical, non- concentric, or that a spherical inner member may co-operate with a cylindrical outer one. It also states that the surface bond may be derived entirely by vulcanization. This subject matter does not appear in the Specification as accepted.

Title: Blown tube production
IPC: B29C48/10
Filed: 1972-08-21
Abstract: 1396749 Non-crystalline films; extruded tubular film LECO INDUSTRIES Ltd 21 Aug 1972 38782/72 Headings B5B and B5A Tubular film is extruded and inflated from conventional die 14 and cooled in a three-stage process. In the first stage the tube is cooled to a temperature at which crystallites are formed. This is accomplished by means of air-ring A, the cooling air being supplied by conduit 49 and playing on to the film through aperture 48. In the second stage, the film is annealed for a time sufficient to permit amorphous areas to form. This occurs in a dwell chamber C comprising housing 52 and a conduit 54 connected to a vacuum source. In the third stage the film is cooled by airring B, of similar construction to A, so that it solidifies without the formation of crystals. The resulting film, which is preferably of polyethylene, has crystallites dispersed throughout amorphous areas and is stated to have a high gloss and low haze (high transparency) in addition to improved tensile strength.

Patent GB-1021475-A (GB)
Title: A process of preparing trialkali metal nitrilotriacetates
IPC: C07F1/04
Filed: 1962-10-18
Abstract: Crystalline trialkali metal nitrilotriacetates are covered from a saponification solution, obtained by treating nitriloacetonitrile with alkali metal hydroxide at 90-100 DEG  C. and containing about 40% by weight of the triacetate, by mixing said saponification solution with a 50% by weight aqueous solution of the same alkali metal hydroxide at 60-100 DEG  C., allowing the mixture to cool to 60 DEG  C. or below, and separating the trialkali metal nitriloacetate crystals which form.  The process can be effected in a continuous manner by adding fresh nitriloacetonitrile to the mother liquor from the crystals and saponifying this mixture by heating to 90-100 DEG C., sufficient alkali metal hydroxide solution having been added at the crystallization stage to saponify all the added nitrilotriacetonitrile; this saponification mixture is then used as the starting material for the crystallization procedure.  The continuous mode of operation is illustrated with reference to diagrammatic drawings (not shown).  It is preferred to mix the alkali metal hydroxide solution and the saponification mixture in stages and, in the continuous process, the wash the crystals with part of the saponification mixture. The examples relate to trisodium nitrilotriacetate.

Abstract: 954,652. Overhead - travelling cranes. JOSEPH LUCAS (INDUSTRIES) Ltd. Nov. 28' 1960 [Nov. 30, 1959], No. 40551/59. Heading B8B. Changes in the angular relationship between a crane bridge 11, Fig. 1, and a track 10 are sensed and the relationship restored by rollers 40, 42a, Fig. 3 which are held on the side of one track 10 by a spring 43 and mounted on horizontal levers 39, 42 pivoted to the frame 11 and connected together by links 38, 41, angular movement of the lever 38 controlling the speed of the two driving motors of the crane bridge. The crane is constructed as described in Specification 954,653, the proportioning valves referred to therein for the two crane bridge drive motors 13 being controlled by the lever 38 through links 44, 45, 46, 48, 49, 51, 52 and the piston and cylinder 50. The lever 52 is the actuating rod for the proportioning valves and opposite ends of the cylinder 50 are connected to the reversing and throttling valve which controls the motors 13. The arrangement is such that when the reversing valve is set to move the crab in one direction the pin on the lever 48 occupies one end of the slot 46 whilst when it is set to move the crab in the reverse direction the piston-rod 49 is moved to cause the pin to occupy the other end of the slot 46. Moreover, a given angular movement of the lever 45 in one direction will result in a certain angular movement of the lever 51 in one direction when the piston-rod 49 is in one position, but an equal but opposite angular movement of the lever 51 if the piston-rod is in the alternative position. Thus control of the proportioning valves is independent of the direction of travel of the crab.
