Title: Improvements in or relating to synthetic resins and processes of making the same
IPC: C08G8/26
Filed: 1928-10-20
Abstract: 299,065. British Celanese, Ltd., (Assignees of Moss, W. H.). Oct. 21, 1927, [Convention date]. Phenol-ketone-aldehyde resins are produced by condensing one molecule of a phenol-ketone condensation product with less than two molecules of an aldehyde. In an example 1 molecule of diphenylol propane is heated with one molecule of formaldehyde or with up to 10 per cent excess of this with 0.1 to 5 per cent of a molecule of a catalyst such as phosphoric acid, the mixture being heated with stirring at above 100‹ C. The lower layer is washed with water or sodium carbonate solution and (with or without the addition of other substances such as oils, solvents or catalysts in any stage of the purification) may be treated by steam or vacuum distillation to remove impurities. It is finally washed and melted and heated to 180-200‹ C. It melts at 140- 150‹ C. Instead of phosphoric acid there may be' used other acids such as boric, hydrochloric, and sulphuric acid, and instead of diphenylol propane similar bodies derived from other ketones such as ethyl methyl ketone or diethyl ketone and other phenols such as cresol. The products are suitable for cellulose ester lacquers and for plastic compositions. Specification 299,781, [Class 95, Paints &c.], is referred to.

Filed: 1921-11-15
Abstract: 171,690. Ateliers Heuze, Malevez, et Simon RÚunis, Soc. Anon. Nov. 16, 1920, [Convention date]. Flat extended surfaces, surfacing and polishing.-Glass, mirrors, &c. are mounted, for grinding and polishing, on tables T adapted to be passed in a series, with their adjacent ends connected, beneath sets of discs F, G, each of which performs one and the same operation only on the successive pieces of glass &c., for example smoothing, second grinding, or polishing. The sets of discs are arranged so as to leaves spaces O between consecutive sets, wherein the glass is washed to remove the material employed by the previous set; brushing- devices P also assist in the washing. The tables are moved along guides by rack-and-pinion gearing or by an endless chain &c., and, as each table emerges from the last set of discs, it is removed from the machine by a conveyer for removal of the glass and attachment of a new glass piece; it is then re-inserted in the machine at the commencement of the series. The discs of each set are rotated about axes perpendicular to the surface of the glass and are supported by frames E, which are reciprocated across the tables by eccentrics m, the frames carrying racks j resting on the toothed upper ends of levers H; the frames may be removed and replaced by others. The reciprocating movement of the frames may be replaced by a circularmovement about an axis perpendicular to the surface of the glass, the discs having planetary movement. The discs may be raised and lowered, and their pressure on the work may be adjusted.

Filed: 1937-11-10
Abstract: 488,001. Twisting wires together. HOFFMANN, E. Nov. 10, 1937, No. 30875. [Class 83 (iv)] In a bale-tying machine a tensioning device and a twisting pinion are mechanically coupled and operated by a single lever to effect simultaneously the tensioning and twisting. The ends of the wire are gripped by a clamp 3 on a lever 2 and a clamp 4 on a lever 21. The wires pass through a slotted pinion 5 rotated by a gear train from a shaft 7a carrying a lever 8. The lever 8 is swung to rock the shaft 7a and attached cams 9 act on rollers 10 to push the levers apart and tension the wire and simultaneously rotate the pinion to effect the twisting. The lever 8 then engages a pin 15 on a lever 13 to thrust it on to a cutter 12 which is depressed to shear the wire. When the lever 8 is released a spring 31 raises the cutter. The machine is then placed on another package and the lever 8 is rocked in the opposite direction to tension and twist the wire. When the lever 8 reaches the end of its stroke it engages a lug on a lever 14 which depresses the lever 13 to again actuate the cutter.

Title: Pole-Changing Electrical Machine
IPC: H02K17/14
Filed: 1967-07-05
Abstract: 1,157,260. Control of A.C. motors; electric motors. LICENTIA PATENT-VERWALTUNGS G.m.b.H. 5 July, 1967 [7 July, 1966; 28 Nov., 1966], No. 30958/67. Headings H2A and H2J. [Also in Division G3] A motor driving a washing machine is adapted for pole-changing and is further controlled by means of a triac or back-to-back thyristors connected to the stator winding. Control signals for the thyristors are derived from a generator installed in the motor and driven from its shaft, these signals adjusting the firing-angle of the thyristors through a pulse-generating circuit. If the speed of the motor is reduced due to increased loading, the firing-angle of the thyristors is advanced to restore the speed to its desired value. In one arrangement, the motor shaft carries a projection coacting with a permanent magnet on the rotor of the generator which is driven thereby. In another embodiment, the rotor of the control generator is constructed in the form of a permanent magnet mounted directly on the motor shaft. The stator of the control generator and a bearing member for the motor may be accommodated in a single bore of an end bracket. Alternatively, the stator of the generator is fitted into a widened portion of the bracket. The control generator and bearing member may be mounted on different sides of the bracket.

Title: Improvements relating to coated paper
IPC: D21H25/14
Filed: 1962-08-14
Abstract: 973,275. Calendering coated paper. S. D. WARREN CO. Aug.14, 1962 [Aug. 29, 1961], No. 31158/62. Heading D1L. [Also in Division B2] A method of forming a smooth-surfaced coated paper web comprises the steps of applying to a paper web a coating composition containing a mineral pigment and a hydrophilic adhesive binder, drying the coated web, moistening the surface of the coating and passing the moistened coated web through the nip between a polished finishing drum and a backing roller, the pressure at the nip and the moistening of the coating being controlled so that the coating is sufficiently dry not to adhere to the polished finishing drum but is sufficiently moist to allow a smoothing action whereby raised areas of the coating (Fig. 2 not shown) are swaged downwardly to provide an even surface and, so that the paper fibres remain sufficiently dry to resist permanent compression from the pressure between the rolls. The water may be applied to the web prior to or directly at the nip between the rolls (Fig. 3 not shown). The provision of a rubber covered backing roll allows for adjustment of the nip height and therefore also of the degree of smoothing achieved on the coating at a given nip pressure. A suitable coating composition contains 100 parts by weight of mineral pigment, e.g. clay and 20 parts by weight of adhesive binder made up equally of alkaline casin and a latex adhesive. Preferably the binder is a protein adhesive which has been peptised in an acidic or neutral salt and subsequently dispersed in the coating composition. Improved malleability of the coating is obtained by treating it with an acid or acid salt in addition to the moistening process before passing through the nip. The value of the process is particularly evident in the improved gloss and printing characteristics of the paper obtained when the process is followed by further surface treatment processes such as calendering, supercalendering, passing the coated web through a hot nip of rollers maintained above 212‹F., as described in Example 8 of Specification 854,500, or a cast coating process in which the coating is re-wetted and pressed against a polished finishing drum as described in Specification 714,723. Specifications 966,225 and 973,274 also are referred to.
