IPC: B31F1/28
Filed: 1952-03-18
Abstract: 729,750. Supporting and mounting bearings. MOLINS MACHINE CO., Ltd. March 12, 1953 [March 18, 1952], No. 6995/52. Class 12 (1). A device for adjustably determinging the position of an adjustable roller 2 relative to that of an opposed roller 1 comprises a screw member 9 connected to a pivoted plate 7 carrying the movable roller 2, which member 9 is prevented from movement towards the opposed roller 1 by a nut member 16 and is yieldingly restrained from movement in the opposite direction by a spring 11. The nut has a convex portion bearing against a fixed stop' 17, and a worm-wheel 18 is formed upon it and is arranged to engage a worm 19. The outer surface of the worm-wheel 18 is made convex so that the teeth may remain in operative engagement with the worm for different angular positions of the member 9. Rotation of the worm 19 is effected by rotation of a hand wheel 23 secured to the opposite end of a shaft 20 on which the worm 19 is mounted. Simultaneous adjustment of a bearing at the other end of the roll may be effected if a sleeve 21 carrying a second worm is coupled directly to the hand wheel 23. A hand wheel 22 on the sleeve 21 enables independent adjustment of the second bearing when the sleeve 21 is disengaged from the hand wheel 23.

Title: A process for preparing readily dyeable polypropylene fibers
IPC: D06P5/22
Filed: 1961-02-27
Abstract: Polypropylene fibres of enhanced dyeability are made by ultra-violet irradiation of the fibres in the presence of a sensitizer, followed by graft polymerization with monomeric vinyl compound having epoxy groups, and treating the fibres with a solution of a substance selected from the group consisting of water-soluble hydroxyamines and water-soluble salts of amino acids in a mixture of dimethyl formamide and water.  Irradiation may be effected in air or in vacuo for from 30 mins. to 2 hours, and the fibres may be treated with a solution of the sensitizer, or fibres made from a melt or spinning solution in which a sensitizer is incorporated may be used.  Specified sensitizers include acetophenone, benzophenone, and products sold under the Registered Trade Mark "Nvinul".  Specified monomeric vinyl compounds having epoxy groups include glycidyl acrylate, glycidyl methacrylate and glycidylvinylurethane.  Graft polymerization may also be effected with a mixture of monomeric vinyl compounds having epoxy groups with other vinyl compounds, e.g. vinyl acetate, methyl methacrylate and acrylonitrile.  The weight increase of the fibres after graft polymerization is desirably 20-30%.  Specified hydroxyamines include diethanolamine, and specified amino acid salts include the sodium salts of monoamino monocarboxylic acids, e.g. glycine and alanine, of monoaminodicarboxylic acids, e.g. glutamic acid, and of diaminomonocarboxylic acids, e.g. lysine. A preferred treating solution is a 30-50% by weight solution of the hydroxyamine or amino-acid salt in a mixture of 30-70% by weight water and 70-30% by weight dimethylformamide.

Title: Method of and means for testing the purity of solid or liquid hydrocarbons
IPC: G01N27/00
Filed: 1930-03-05
Abstract: <PICT:0345464/III/1> The purity of solid or liquid hydrocarbons is tested by subjecting the material to the action of short electric waves, for example those having a frequency of 10<8> Hertz, and measuring the resultant rise of temperature.  The hydrocarbon to be tested, such as transformer oil, is contained in a beaker 1 arranged between condenser plates 2, 3 fed by a thermionic valve 4 generating high-frequency oscillations.  The grid and anode of the valve 4 are connected by a stirrup inductance 5 inductively coupled to a wire 9 connected to the condenser plates 2, 3.  The resulting rise of temperature is measured by a thermo-couple 10 fused into a glass tube 11 and connected to a measuring instrument 12.  The oil under test may be subjected to the magnetic field of a coil of a few turns surrounding the beaker 1 instead of to the electric field of the condenser plates 2, 3.  The Specification as open to inspection under Sect. 91 (3) (a) states also that two or more thermionic valves may be connected in parallel.  This subject-matter does not appear in the Specification as accepted.

Abstract: 935,434. Structural joints. ALFRED IMHOF Ltd. Feb. 21, 1961 [March 1, 1960; June 9, 1960], Nos. 7286/60 and 20535/60. Class 20 (2). [Also in Group XIV] In a rigid framework comprising frame members 30, 31, each of which is of hollow crosssection, at least at its ends, and connector members A, B, C, each of which has two or more arms extending in the direction of the respective frame members to be received therein so that they are in interlocking engagement therewith, the frame members 30, 31 are each formed with two angled surfaces 34, 35 disposed at a predetermined angle to one another in sliding engagement with complementary angled surfaces formed on the arms 40 of the connector member in such manner that interengagement of the co-operating parts only takes place in the area of the angled surfaces. The arms 40, as shown in Fig. 2, are rectangular in cross-section and the machined faces of the rectangle form two diagonal opposed corners 41, 42 of a rectangle. The framework may be assembled without the use of further fastening means but locking means may be provided. The locking means may consist in forming each free end of the arms 40 with an axial slot 43 to receive a self-tapping screw 44 which, when tightened, is effective to expand the end of the arm 40. Alternatively the end of each arm 40 may be formed with a hole 46 (Fig. 7), to receive a self-tapping screw 47 which bites into the frame member 31. Further alternative locking means comprise a spider-like member 56 having three arms 57 extending from a central hub 58 (Fig. 21). The hub 28 has a threaded aperture to receive a locking screw 59. Each arm 57 is formed with offset fingers 60 for engagement with a transverse slot 61 in the corresponding arm 40. On tightening the screw 59, the arms 57 through their fingers 60, apply a thrust to the respective frame members in one direction and the screw itself applies a thrust in the opposite direction thereby locking the connector and the frame members together. The fingers 60 may be provided with serrated edges. As shown in Fig. 4, the outer walls 36 of the frame members are extended at 37 to form a rebate, having a groove 38 to receive perforated or imperforate covering panels 39. As shown in Fig. 8, the connector A is provided on two sides of and in alignment with one of the arms, with transverse grooves 48, for engagement by a frame member so that one arm of the connector can be positioned in any position along the length of the frame member. In the corner joint shown in Fig. 9, the joining ends of the frame members 31 are squared-off for engagement with a corner boss 51 formed integral with or attached to the apex of the connector. Alternatively, the joining ends of the frame members are mitred, Fig. 3 (not shown).

Filed: 1937-03-13
Abstract: 492,267. Vehicle &c. lamps. JACKS, S. J. March 13, 1937, No. 7466. [Class 75 (iv)] In a vehicle or like lamp, the electric bulb 22 is adjustable both vertically and horizontally in relation to a fixed reflector 3, the adjustment being effected from a remote control through the medium of one or more Bowden cables. In the form shown, the lamp socket 4 is adjustably secured by a screw 5 within a tube 6, which is pivoted on trunnions 8 in a sleeve 7, the latter being mounted to pivot about vertical pins 13, 13a. The vertical and horizontal movements of the tube 6 about the trunnions 8 and the vertical axis 13, 13a, are effected by Bowden cables 10, 10a, the central wires 9, 9a of which are connected respectively to the tube 6 by a sliding sleeve 12 and a spring 15, and to the pin 13a by a spring 40, Fig. 3, pivoted arms 34, 35, 36, and a bifurcated member 32. The opposite ends of the wires 9, 9a extend to a remote control point, e.g. the dash-board of a vehicle, where they are connected to members 25, 41, Fig. 4, slidable on a base 24. The sliding movements of these members are effected by a single spindle 26 having an operating knob 29, this spindle being directly secured to the member 25 and having splined thereon a worm 43 which engages a screw thread in the member 41. Rotation of the knob 29 thus moves the member 41 to operate the wire 9a while push and pull movements of the knob operate the wire 9. Modifications are referred to in which a single Bowden cable is used to effect both vertical and horizontal adjustments and in which foot-operated means are employed to actuate either or both of the cables 10, 10a.
