Patent GB-573083-A (GB)
Title: Improvements in or relating to the manufacture of synthetic resins
IPC: C09F9/00
Filed: 1942-10-17
Abstract: A resinous product is obtained by heating together an aluminium alcoholate derived from a monohydric aliphatic alcohol containing up to six carbon atoms in the molecular and an aluminium phenate derived from phenol or a homologue thereof.  Preferably, the alcohol and phenol are mixed, the aluminium is dissolved therein, and the mixture is heated to 100-150 DEG  C.  The alcohol and the phenol are preferably used in equimolecular amounts and sufficient aluminium is added to convert the whole into alcoholate and phenate.  In the example, aluminium is dissolved in a mixture of phenol and butyl alcohol and the mixture slowly heated to 100-150 DEG  C.  Prolonged heating reduces the solubility of the resin in solvents.  By adjusting the time of heating, a resin compatible with oils such as linseed oil may be produced.  The mixture of resin and oil may be used for a coating composition, the resin increasing the drying rate of the oil.  One per cent of resin added to castor oil produces a solid vaseline-like product. The reaction may be performed in solution, e.g. in carbon tetrachloride with a catalyst, e.g. sulphur dioxide.  A clear bright red solution of resin is obtained from which the solvent may be recovered by evaporation.  If heated or kept for a long time, the resin will become insoluble even in the solvent used for its preparation.

Filed: 1961-04-25
Abstract: 929,321. Safety devices for steam generators. SPANNER BOILERS Ltd. April 17, 1962 [April 25, 1961], No. 14857/61. Class 51 (1). [Also in Group XI] A safety device for an oil-fired steam generator comprises a chamber 13 normally filled with water which may be discharged gravitationally through a pipe 12 if the level of water 15 in the steam generator falls below the outlet of the pipe 12. If this occurs steam enters the chamber and melts a fusible element 21 incorporated therein which forms part of the electrical circuit of the oil burner supply pump. The element 21 may consist of an uninsulated rod (Fig. 4, not shown), or may be enclosed within an insulating sleeve and may be held in tension by springs at either end (Fig. 3, not shown) or as described in the Provisional Specification by a spring-pressed arm or may be a wire enclosed for most of its length by two insulating sleeves within an outer metal tube (Fig. 2, not shown). If the element 21 is insulated from the water it may carry the mains voltage but otherwise is connected to the oil burner motor circuit through a relay and only carries a low voltage. In a modification the entry to the chamber is closed by a fusible plug, this plug being melted first by the steam before it can enter the chamber to fuse the element 21. In a further modification the pipe enters the generator horizontally at the predetermined level (Fig. 5, not shown).

Title: Gauge for measuring absolute or cosmic velocity and direction
IPC: G01S11/16
Filed: 1958-05-12
Abstract: 884,830. Measuring velocity. BRISCOE, J. A. Aug. 10, 1959 [May 12, 1958], No. 15089/58. Class 40(7). Relates to means for measuring absolute velocity and direction of motion in space utilizing the alleged effect that the velocity of propagation of electromagnetic waves is dependent on the absolute velocity of the source. As shown two radio receivers 5, 5a are spaced symmetrically on either side of a radio transmitter 1, the equipment being mounted on a rotatable frame. The electrical outputs from the receivers 5, 5a are converted by crystal transducers 6, 6a into corresponding mechanical vibrations which are applied via mechanical wave conductors 7, 7a to adjacent crystal transducers 8, 8a whose electrical outputs are applied through harmonic generators 9, 9a to a phase comparator 10. The transmitter 1 may transmit modulated or unmodulated signals. In operation the direction of the frame and the frequency of the transmitted signal are adjusted until the corresponding outputs from the harmonic generators 9, 9a are in anti-phase. When this obtains the frame is aligned with the direction of motion and the magnitude of the velocity is given as a function of the frequency of the signals from the harmonic generators 9, 9a, the spacing of the receivers and the velocity of propagation of radio waves from a stationary source. The sense of the velocity is determined by reducing, e.g. halving, the frequency of the transmitted signal and moving the transmitter towards the receiver 5a a predetermined fraction, e.g. #, of the wavelength of the resultant signals from the harmonic generators 9, 9a, said signals being then in phase or out of phase according to whether the direction of motion is such that the receiver 5a is in front of or behind the transmitter 1. The principles of the invention are explained with reference to an analogous arrangement, Fig. 1 (not shown), using sound waves.

Abstract: 861,108. Finishing yarns. HEBERLEIN & CO. A. G. May 4, 1959 [June 3, 1958], No. 15225/59. Class 120(3) In the manufacture of bulked yarn, a filamentary or staple yarn e.g. of polyamides, polyesters, polyacrylonitrile, cellulose acetate, or silk, is simultaneously forwarded at high speed and converted to plastic condition by a fluid stream e.g. in a jet or nozzle, and is struck against a surface, whereby the yarn is mechanically deformed and the fluid is dispersed. The deformed yarn is set by reversion to a non-plastic condition. The fluid may be a hot gas or gaseous mixture, e.g. hot air or steam, optionally containing vapours of volatile substances such as organic swelling agents or solvents, or a (hot) liquid which plasticizes the yarn e.g. a solution of a swelling agent in a volatile organic solvent. The impact surface is flat or arcuate, disposed normally or obliquely to the yarn or nozzle axis, and it may be permeable to the fluid e.g. of open mesh, fabric, porcelain, or foamed rubber, or it may be corrugated or grained to effect fluid dispersal. The yarn may be withdrawn from the surface at a speed which is 0À5 to 0À75 of the feed speed thereto. As shown, yarn is fed by rollers 2, 3, to a nozzle 3 consisting of coaxial tubes 4, 5, along the axis of which the yarn is passed by compressed air entering the nozzle through an inlet 8 and preheated, as by an electric heating coil (not shown) on tube 5. The yarn emerges through an aperture 7, strikes a rotating, metal screening drum 9, and the set, bulked yarn is withdrawn under tension by a discharge roll 10 and wind-up spool 11. An injector nozzle, Fig. 4 (not shown), comprises coaxial tubes forming a venturi, yarn-outlet orifice.
