Filed: 1947-08-01
Abstract: Solid infusible products are prepared by reacting formaldehyde, paraformaldehyde, trioxymethylene, furfuraldehyde or hexamethylene tetramine with a solution in styrene of a polymer of cashew nut shell liquid, marking nut shell liquid or Japanese lac.  The polymer is produced by heating with an acid polymerizing agent, e.g. sulphuric, hydrochloric or phosphoric acid, zinc chloride, stannous chloride, phosphorous oxychloride, aluminium chloride, diethyl sulphate or tributyl phosphate until a solution thereof in an equal weight of xylene has a viscosity at 25 DEG  C. of 40-200 centipoises.  The cashew nut shell liquid may be treated initially to reduce its vesicant properties, e.g. as in U.S.A. Specification 2,128,247.  The ratio of styrene to polymer in the solutions is preferably between 1 : 4 and 4 : 1 by weight. The reaction with aldehyde may be carried out at room temperature except when hexamethylenetetramine is the only aldehyde employed when the temperature should be raised to 185-250 DEG  F.  The products may be used for coating fabrics or asbestos, for electrical insulation.  They are infusible, rubbery, flexible materials substantially insoluble in benzol.  Preferably the solutions mixed with aldehyde are used for impregnating or coating and then hardened.  Specification 636,694 also is referred to.

Abstract: 1387687 Current collectors MESSERSCHMITT - BOLKOW - BLOHM GmbH 10 May 1972 [18 June 1971] 21835/72 Heading B7L A device for collecting electrical energy from a fixed conductor rail 1 to feed an electric locomotive comprises an arc electrode 5, Fig. 2, which acts as a guide for the seat of an arc 7 formed between the electrode 5 and the rail 1, in use, and is arranged in the gap of a controllable arc-blowing electromagnet, including exciter winding 6, which acts on the arc so that it moves repeatedly to and fro along the electrode, and means controlling the energization of the magnet so that the arc is stabilized and constantly moved in relation to the electrode but moves at the same average speed as the electrode in relation to the rail. A sliding contact shoe 9 feeds current from the rail 1 to the locomotive when travelling at low speeds and serves for the ignition of the arc 7 which is then transferred by the blowing magnet to the arc electrode 5. To and fro movement of the arc by the electromagnet may be effected in that the winding 6 may be entirely energized and then partially energized via a tapping 14, under the control of control means 17 responsive for example to arc current measured by a sensor 18 and voltage drop along the arc 7 between points 19 and 20. One form of electrode is an elongated annular bar 55, Figs. 5b and 6, electrically and slidably connected to contact shoe 9 by a connecting section 56. A double magnet core 30 has windings 66, 67 and 68 which can be selectively energized such that the arc 7 travels faster along one elongated section of the bar 55 and slower along the other elongated section, due to different strength blowing fields in the gaps 32 and 33 of the magnet core 30. Additional blowing magnets can be provided at each end of the electrode to prevent the arc 7 from travelling beyond these ends and to prevent bulging of the arc in or against the direction of travel. In alternative forms, Figs. 8 and 9 (not shown), the electrode may be driven so as to rotate. An air diverter (81), Fig. 3 (not shown), may be provided to divert air streams opposed to the direction of electrode travel from the area of the blowing field.

Filed: 1959-06-26
Abstract: 849,728. Chucks. BUCK TOOL CO. June 26, 1959, No. 22031/59. Class 83 (3). In a chuck having radially-sliding jaws, wear on the jaws or in the jaw-guideways is taken up by wedges in the guideways. The jaws 11, Fig. 4, in the chuck body 10 are moved radially by an axially-movable ring 12 which engages a bevel 13 on each jaw. Each jaw 11 has projections 19, 20, Fig. 3, which are located in guideways 17, 18, in the body 10, and a wedge 27 in a tapered-recess in the jaw guide engages face 23 of each projection 19, 20. Each wedge is moved radially-inwardly of the body 10 by a screw 33, Fig. 6, having a flange 34 which engages a slot 32 in the wedge, and a spring- washer 36 when deformed in a slot 31 in the wedge, urges the wedge inwardly. In operation, the screw 33 is screwed into the body 10, to force the wedge 27 into engagement with the face 23 on the jaw, and the tapered face 24 in the guideway, due to the washer 36 engaging the slot 31 in the wedge. The screw 33 is then screwed further into the body until the flange 34 engages the forward end of the slot 32, the washer 36 being forced against the end-face 48 of a counterbore 47 in the body, then becoming distorted. As wear occurs, the washer 36 will move the wedge inwardly until it becomes unstressed, and the counterbore 47 can then be deepened and the screw 33 screwed further in the body 10. In a modification, the wedge 27 or the face 24 in the guideways may be made parallel. In a further modification one wedge is used on the face 11a of the jaw.
