Patent GB-935424-A (GB)
Title: Polyether compositions and a process for their preparation
IPC: C07H15/06
Filed: 1960-01-25
Abstract: The invention comprises a composition, for cross-linking polyurethane resins, of (A) at least one poly (hydroxyalkyl) ether of a cyclic sugar and (B) at least one poly (hydroxy alkyl) ether of an open chain aliphatic polyhydroxy alcohol with at least two hydroxy substituents, wherein at least the majority of the hydroxy groups of both compounds (A) and (B) are etherified with hydroxy alkyl groups. The composition may be formed by mixing the performed ethers, but preferably is prepared by mixing the cyclic sugar and the open chain polyhydroxy alcohol and subsequently treating the mixture with an alkylene oxide in the presence of a tertiary amine which is free of labile hydrogens, as a catalyst. Preferably one mole of sugar is mixed with 2 to 3 moles of open chain polyhydroxy alcohol and 0,5 to 2% of tertiary amine based on the weight of the sugar and polyhydroxy compound, and treated with alkylene oxide at 80 to 140 DEG C.  Water may be present in the reaction mixture, preferably not more than one mole per mole of sugar, and preferably 0,5 to 2% by weight of the mixture of polyhydroxy compounds.  Suitable catalysts for the reaction are N methylmorpholine, dimethylethylamine, dimethylaniline, methyldiethylamine and preferably triethylor tripropyl-amine. The sugar specified is sucrose and the open chain polyhydroxy alcohol specified is glycerol.  The process may be carried out batch-wise or continuously.  Examples describe the reaction, in the presence of triethylamine, of cane sugar, glycerol and ethylene or butylene oxides, and beet sugar, glycerol and propylene oxide.  The compositions are used as cross linking agents for polyurethane resins to give products with excellent dimensional stability (see e.g., Specification 935,423).

Title: Improvements in or relating to apparatus for continuously winding threads and like filamentary material on to a succession of bobbins
Inventor: MATTINGLY DENIS ALBERT EDWARD
IPC: B65H67/056
Filed: 1963-05-06
Abstract: 1,090,892. Winding bobbins. KLINGER MANUFACTURING CO. Ltd. April 30, 1964 [May 6, 1963], No. 17888/63. Heading D1J. A method of continuously winding yarn on to successive bobbins comprises feeding yarn onto one bobbin through first traversing means, engaging the yarn and swinging the yarn through an arcuate path so that the yarn is lifted out of the first traversing means and placed in the path of a second traversing means, and feeding the yarn onto another bobbin through said second traversing means. In the embodiment shown when the left hand package has reached a predetermined size, or after a predetermined winding time, sleeve 32 moves to the left to release the right hand bell crank lever 28, 30 to allow the empty bobbin to fall onto its driving roller. Rack 36 is also moved to swing arm 44 upwardly to move the yarn out of the traversing guide 8 of the full bobbin to be caught by the castellations of the snare ring 20 mounted on spindle 18 of the empty bobbin and then to fall into the path of the traversing guide of the empty bobbin. Sleeve 32 now, engages the left hand bell crank lever 28, 30 to lift the full bobbin out of engagement with its driving roller. The yarn between the full and empty bobbins is broken by the difference in speeds between the two bobbins or by a severing device. A single driving roller may be provided for one or more pairs of bobbins. In an apparatus described but not forming part of the invention claimed, a series of traversing guides, one for each pair of a plurality of bobbins, are mounted on a cable oscillated by a cam-as in Specification 885,473. Part of the cable is accumulated in a reserve which is varied in size to shift each guide from one bobbin of a pair to the other bobbin.

Abstract: 461,882. Hydraulic transmission of power. CLAYTON, C. E. EVERY-. (Linderman Devices, Ltd.) June 21, 1935, No. 17916. [Class 69 (ii)] [Also in Groups XXXIV and XXIV] A friction brake or clutch comprises a shoe arranged to be urged to engagement with the surface to which it is to be applied by fluidpressure exerted by an expansible chamber of metal, rectangular in plan and comprising a number of similar shallow intercommunicating compartments, the expansions of which are additive. Figs. 1, 2 show a brake comprising a support 21 with polygonal faces 24 on each of which is an expansible chamber 23 supporting a segmental brake shoe 22 for application to a drum 20. The shoes are radially guided by pins 11. Each chamber is secured to the support 21 by a tubular bolt 28 having apertures 30 through which pressure fluid is supplied from a chamber 25 extending continuously around the faces 24 of the support and having a pipe connection 26. The segments 16 of the friction lining extend from the mid-point of one shoe to that of the next and are attached to one shoe only. One construction of expansible chamber of Z-form Figs. 12, 17 and comprising compartments 61 communicating at the ends 62 is made from two sets of plates 52, 55 of spring steel which are first welded at the edges 53, 54, the two sets being then interfitted and the edges 56, 58 of adjacent plates of the two sets welded together. To ensure substantially parallel movement of the upper and lower faces of the chamber and to prevent the presence of voids between the limbs thereof and consequent lost motion, spacers 63 of rigid material may be provided and are preferably cast in situ. In another construction also of Z-form, two plates 45, 46, Fig. 11 are welded together at the edges and the end parts are then bent in opposite directions to overlap the middle part about ribs 50 formed in the plates. A connection 47 for the pressure fluid is provided. Instead, two plates may first be bent to Z-form before being interfitted and welded together. Fig. 21 shows a bellows form of device comprising pairs of rectangular plates welded together at the outer edges 74, one plate of a pair having a flange 69 around a central aperture which is bent over the corresponding edge of a plate of the adjacent pair, or the inner edges of the plates may be connected together by separate eyelets. The apertures diminish progressively in size so that the device may completely collapse.

Title: Cooling curve computer

Filed: 1975-05-01
Abstract: 1461756 Measuring carbon content of cast iron electrically FORD MOTOR CO Ltd 1 May 1975 [22 May 1974] 18178/75 Heading G1N The percentage carbon content of a sample of a molten cast iron alloy is determined by measuring TL, the temperature at which a phase change from liquid to solid occurs, TS, the temperature at which the last liquid solidifies, and TE, the temperature at which the solid alloy is transformed into a plurality of solid phases and combining these values mathematically in accordance with known empirical formulae to determine the percentage carbon content. The temperature of the molten iron as measured by a thermocouple 12, Fig. 1, and amplified at 18, 20 is fed to a track and hold circuit 22, whose output E5 follows the temperature signal El during track periods and stores the last El  value during hold periods, the duration of the tack and hold periods being controlled by clock circuit 36. The change in El is sensed by a difference amplifier 24 and is positive when the temperature is falling and is obtained as signal E7 from amplifier 26, and is negative when the temperature rises and produces signal E8 from amplifier 30. When the E7 signal falls below a saturation level of amplifier 26 for the first time, the measured temperature signal E1 represents TL and is fed to a first sample and hold circuit 42. When it occurs the second time, the temperature signal El represent TS and is fed to a second sample and hold circuit 44. The TL, TS signals are mathematically combined as required at 58, 62 to produce at 64 a voltage representing the percentage carbon equivalent content of the tested iron alloy. A similar arrangement determines the percentage silicon and carbon content from the value of TE. The circuit arrangement includes an alarm relay 48 which is energized when TL is excessively high, an alarm relay 68 energized when the thermocouple is open-circuit, or when the temperature signal representing TS is stored at 44, indicating the completion of a measuring cycle.
