Title: Process for the production of synthetic resins from alcoholamines and organic acids
Filed: 1931-06-23
Abstract: Polybasic carboxylic acids or anhydrides thereof are condensed with alcoholamines with or without the addition of polyhydric alcohols to give a thermo-hardening resinous product.  The products may be used as softening agents for artificial and natural resins, as vulcanization accelerators and as a catalyst and softening agent with phenol-formaldehyde condensation products.  As polybasic carboxylic acids there may be used phthalic acid or anhydride, adipic acid, sebacic acid, citric acid, benzophenone dicarboxylic acid, succinic acid or its homologues, aromatic di- and polycarboxylic acids alone or in mixture.  As alcoholamines there may be used tri-, di- or monoethanolamine in a pure form or in mixtures such as technical ethanolamine mixtures and they may be diluted with glycerol or other polyhydric alcohols.  Soaps appear to be first formed and these are transposed into esters of the amines on strong heating. Acid esters still soluble in alcohol or acid or neutral ester salts may be used as softening agents for lacquers or for synthetic resins capable of being hardened.  After hardening they have adhesive properties.  In examples, (1) commercial triethanolamine is condensed with adipic acid to give a product soluble in alcohol which on further heating is converted into an insoluble gummy elastic and gelatinous material. (2) Triethanolamine is heated with phthalic anhydride.  (3) Diethanolamine is heated with citric acid.  (4) Triethanolamine is heated with a mixture of succinic acid and phthalic acid anhydride. (5) A mixture of mono- and diethanolamine is heated with adipic acid. (6) A mixture of technical triethanolamine and glycerol is heated with a mixture of phthalic acid anhydride is heated with a mixture of a polyglycerol (corresponding to diglycerol) and tributanolamine. (8) Phthalic acid anhydride is heated with diethylmonoglycerolamine.ALSO:Condensation products of polycarboxylic acids or anhydrides, such as phthalic acid, phthalic anhydride, adipic acid, sebacic acid, citric acid, benzophenone dicarboxylic acid, and succinic acid and its homologues, and alcoholamines, such as mono-, di-, and triethanolamine, and glycerolamines, with or without the addition of polyhydric alcohols such as glycerol are suitable for vulcanization accelerators.

Abstract: 572,560. Carding-engines. PARKER, T. H. Nov. 10, 1943, Nos. 18658/43 and 6102/44. [Class 120 (i)] In a carding engine having means for driving the cylinder from the doffer during slow grinding and in which the flats are normally driven at a relatively slow speed when carding, alternative means are provided for driving the flats from the engine drive at a relatively faster speed for setting and/or for driving the flats while slow grinding. In the modification of Fig. 1, the usual flat-driving pulley is removed and replaced by a stepped pulley a<1>, a<2>. For setting flats, the pulley a<2> is driven from the pulley i on the cylinder shaft f, the normal belt from i to the licker-in i<1> being removed. The cylinder g is then driven from the fixed pulley on the shaft f. For slow grinding, the pulley a<1> is driven from the pulley i by a crossed belt k, the brushes l also being driven from pulley i. The cylinder g is driven from the doffer by pulleys m<1>, i and the belt m while the grinders n are driven from the loose pulley on the cylinder shaft f. In the modification of Fig. 4, for setting the flats, a pulley on the doffer shaft, driven from the loose pulley on the cylinder shaft f, drives the pulley a<2> of the flat-driving pair a\ a<2> through the pulley m<1>, on the other end of the doffer shaft, and a crossed belt q. In this latter modification, the cylinder g is stationary while setting the flats. For slow grinding, the machine is arranged for drive as in the modification of Fig. 1.

Abstract: 477,168. Venting-devices for casks &c. CLAYTON, J. July 6, 1936, No. 18697. [Class 21] A sealing and venting device for beer &c. casks &c. comprises a metal peg a with a longitudinal bore a<1> and with a conical portion a<2> on which a sleeve b is revolubly mounted, the sleeve having tubular extensions c, f, one of which carries a cap e apertured at e', the aperture being closed by a spring-pressed ball d. Any other suitable valve may be employed. Rotation of sleeve b can bring either of extensions c, f into register with an aperture a<3> communicating with the bore a<1>. Fermentation gases can pass out through passage f while vent air can enter during drawing-off of the contents through the aperture e<1>. To clear the bore after fermentation, a screw-cap h carrying a rod h<1> is unscrewed and the rod moved upwardly, thus dislodging obstructions. A spring k ensures contact between the sleeve b and the conical surface of the peg. Rotation of the sleeve is limited by a pin l which engages one of a pair of diametrically opposite stops b<2>.

Title: Improvements in means for transferring coded information for example in train describer systems

Abstract: 949,830. Electric selective signalling systems; magnetic shift registers. WESTING- HOUSE BRAKE & SIGNAL CO. Ltd. May 24, 1961 [May 27, 1960], No. 18753/60. Headings G4C and G4H. [Also in Division H3] In a train describer system, information is transferred between transfluxor shift register stores provided with means for displaying stored information. One or more stores are located at each signal box, and the description appertaining to a train is automatically transferred between signal boxes as the train travels between the corresponding track sections. Data may be entered into the transfluxor devices 11, 12 by means of windings S either in serial or parallel mode. Drive and prima pulses on windings DP, PP produce D.C. outputs OP1, OP2 which may be used to illuminate lamps after recoding, for example from 2 out of 5 code. Each shift pulse on windings AP resets the transfluxors 11,12 and the intermediate storage capacitors C are charged to a high or low potential in accordance with the signal read out on winding U. At the end of the shift pulse', capacitor C discharges to set the next transfluxor device by way of winding S. The intermediate storage device may alternatively be a magnetic core, in which case additional pulses interlaced with the shift pulses are used to read out the cores into the succeeding transfluxors. If each information group is prefaced by a "1" a "store full" indication may be obtained from the final transfluxor or from a bi-stable circuit coupled to the last intermediate storage device.

Abstract: 1481482 Automatic control MINNESOTA MINING & MFG CO 5 May 1975 [6 May 1974]  18778/75 Heading G3N The position of a mirror 10, mounted on a pivotted lever 12, is controlled by the energization of a coil 14 of an electromagnet actuator having a magnetic flux source 16. The actual position of the mirror is determined by an opto-electric transducer wherein a shutter 40, coupled to the lever 12, intercepts the uniform light flux at an apertures 36, 38 from a lamp, or LED, 26 through lenses 28, 32. The flux is directed by a lens 30 on to a photodiode 52. The output of the photo-diode is fed through an amplifier 42 to provide an actual position signal 18 which is compared with a command signal 22 in an comparator amplifier 20. The output signal 24 from amplifier 20 determines the energization of the coil 4 and the consequential movement of the mirror 10 to a desired position. Facilities are provided for automatic calibration of the lamp 26. Known inaccuracies in mirror arrangement or position transducer can be corrected by approximately shaping the aperture 38. It is stated that a beam may be positioned in two directions by the use of two mirrors, and that the apparatus can be used for precise movement of other devices, such as, a lens, diffraction grating, prism or pointer.
