Patent GB-880384-A (GB)
Title: Improvements in polyhydrous resins
Inventor: POSWICK JEAN
IPC: C08G18/48
Filed: 1959-03-09
Abstract: A varnish is obtained by mixing a de-epoxidized epoxy resin, that is a resin wherein the epoxy groups are suppressed by reaction giving rise to an hydroxyl group for each epoxy group originally present, and a stoichiometric quantity of masked polyisocyanates calculated according to the hydroxyl equivalent of the de-epoxidized resin and dissolving it in an appropriate solvent.  De-epoxidation may be effected by reaction of the epoxy resin with an organic mono-acid, a mono-alcohol, a monohydric phenol or monoamines, or which converts the epoxy group initially present to a -CH(OH) CH2R group (where R is an acid, alkylol, crylol or amino radical) or by hydrogenation.  The de-epoxidation can be effected in the presence of triethylamine, potassium hydroxide or Friedel crafts catalysts, e.g. boron fluoride. In examples an epoxy resin of molecular weight 1400 and epoxide equivalent about 980 from bisphenol A and epichlorhydrin is refluxed in ethylene glycol monoethyl ether acetate and diethylene glycol diethyl ether with (1) acetic acid in the presence of triethylamine. When the epoxide equivalent falls to practically zero a masked isocyanate from tolyl diisocyanate, hexane triol and phenol is added to the solution.  The varnish obtained is applied to copper strips and baked at 150 DEG C.  (2) The same resin and solvents are heated with phenol and caustic potash. After neutralization with acid the same masked isocyanate as in (1) is added to give a varnish.

Abstract: 741,098. Purifying &c. water &c. PERMUTIT CO., Ltd. March 17, 1954 [March 24, 1953], No. 8109/53. Class 46. In an ion-exchange process, particles of ionexchange material flow in dispersion in the liquid and turbulence is imposed on relatively slow longitudinal motion of the particles. Water such as tap water flows upwardly through ionexchange material, such as beads of a sulphonated styrene co-polymer, moving downwards in a tubular vessel 20 and being gradually withdrawn from the base thereof to be fed by the head of water in the vessel 20 to the top of a tubular vessel 23 for regeneration and rinsing. Annular partitions divide the vessel 23 into compartments in each of which is a disc or set of vanes mounted upon a vertical shaft, rotation of which creates the turbulence. Material descends in the vessel against an upward flow of softened water introduced at the bottom, this flow, in the upper part of the vessel, carrying with it regenerant entering the vessel midway at 24. The rate of flow is controlled by adjusting the discs or one of them relatively to the annular portion or the adjacent one. Treated water fed by a pump 31 actuates an injector 30 to feed the regenerated material back to the top of the vessel 20. Regeneration and rinsing may be effected in separate vessels and the spent ion-exchange material be withdrawn from the top of the treating vessel. The agitation vessel may be arranged horizontally.

Aeroplanes; planes, arrangement of; propelling; steering. - An aeroplane comprises a biplane structure pivoted to the fuselage about a transverse axis and carrying propellers between the planes, means being provided for swinging the propellers laterally irrespective of the angular position of the planes. A modification is also described in which the propellers can also be swung vertically relatively to the planes. Fig. 1 shows two biplane structures 2, 3 which are similarly mounted on the fuselage. The structure 2 is rigidly secured to a transverse tube 4 pivoted in the fuselage and serving as a housing for a transverse shaft which drives two propellers 16. The centre of the tube 4 is enlarged to accommodate gearing and slotted to admit the longitudinallyarranged shaft of an engine in the fuselage. This engine may also drive smaller propellers 27 mounted in the rear structure 3; or a separate engine may be employed. Enlargements 4b on the tube 4 accommodate bevel-gears which drive vertical shafts about which gear-boxes 17 can swivel, the shafts of the propellers 16 being driven by the vertical shafts through bevel-gears within the boxes 17. Free-wheel clutches are arranged between the propeller shafts and the gearing. The front ends of the propeller shafts work in guides 18 and are moved by an endless cord 20 passed around pulleys on the ends of the tube 4 and over a drum 24, Fig. 3, operated by a hand-wheel 26. Similar connections extend from a drum 30 to the propellers 27, which are moved simultaneously with the propellers 16 but in opposite directions. The structure 2 is moved about the axis of the tube 4 by a link 33 and lever 32, Fig. 3, operated by a screwed shaft and handwheel 31. From the lever 32 a rod 34 may extend to similar mechanism on the rear structures 3 so as to tilt it in unison with the structure 2.

Title: Improvements in lathes for turning shells and the like
IPC: B23B5/00
Filed: 1940-02-23
Abstract: 541,801. Turning projectiles. HEPBURN, J. T. Feb. 23, 1940, No. 8724/41. Divided out of 541,777. [Class 83 (iii)] A shell-turning lathe has a longitudinally movable saddle with a mechanical drive, including a clutch, for moving the saddle towards the headstock and fluid pressure means for retracting the saddle the clutch being engaged to complete the mechanical drive by fluid pressure means which are automatically actuated to disengage the clutch when fluid pressure is applied to the means for retracting the saddle. The shell is mounted between an expanding driver and a tailstock in the manner described in Specification 541,777. A shaft 50 driven by a chain 49 is connected through worm gearing 51 and clutch 54 to a shaft 53 connected by gears 60, 61 to a rack 62 on the saddle. The clutch is operated by a fluid pressure cylinder 58. Return movement of the saddle is effected by a cylinder 63 after disengagement of the clutch. In operation, after positioning the shell a foot valve 76 is operated to admit air to lines 78, 79 to grip the work. A switch 80 is then pressed to start the spindle driving mechanism (not shown). Connected to the main air line is a valve 81 having a foot-controlled bleeder valve 83 which allows air flow to lines 84...87. This engages the clutch 54 and starts the mechanical saddle feed. At the same time the cylinder 44 is actuated (line 85) to impart cross feed to the tools, the wedges 47, 48, ensuring a gradual approach. At a predetermined point the saddle engages a valve 88 which allows air flow to cylinders 67 to feed the cutting-off tools as described in Specification 541,799. When the saddle completes its movement it actuates a valve 92 which directs pressure to line 93 thus disengaging the clutch 54, and, through delay valve 95, actuating the cylinder 63 to withdraw the saddle. At the end of the operation, valve 77 is actuated to admit pressure to line 100 to withdraw the tailstock and disengage the driver. Specifications 541,800 and 541,802 also are referred to.

Abstract: 437,788. Thermionic valves; valve generating and modulating circuits. MARCONI'S WIRELESS TELEGRAPH CO., Ltd., Electra House, Victoria Embankment, London.-(Assignees of Hansell, C. W. ; Port Jefferson, Long Island, New York, U.S.A.) March 20, 1935, No. 8731. Convention date, March 20, 1934. [Classes 39 (i) and 40 (v)] A short-wave high-frequency generator consists of a cathode 2, perforated anode 4 and a negatively-biassed deflecting electrode 6, which as shown extends symmetrically about the anode from the side nearer the cathode to the side remote therefrom. The electron stream from the cathode is accelerated by the anode and due to inequality of potentials in the anode flows say to the right and is deflected round the right-hand part of the electrode ; as it impinges on the stream from the cathode the stream flow around the right hand part deflects the new stream past and forms a flow around the left hand part, this process being repeated and giving rise to the desired oscillations. These are taken up by the support for the anode and may be radiated directly or through a transformer 17 to an antennµ 23. A shield 12 protects the upper pinch 5 from bombardment. The electrode 6 may be of metal or of insulating material which may become charged unevenly and improve working thereby ; if of glass the surface is coated with carbon to reduce secondary emission. Radiation may be increased by suitably dimensioning the anode so that its natural oscillation period corresponds to the frequency generated; or the deflector electrode 6 may be so tuned, or an external radiator may be coupled to the deflector or anode and tuned to the frequency or a harmonic. A condenser 13 with sliding contact 14 is used for tuning in the output circuit. Modulation of the oscillations may be effected by varying the potentials of the anode or electrode or of both to produce keying or modulation of the frequency or amplitude or both; speech waves applied to a microphone 18 and amplified by a valve 19 may be used with the Heising method, CH being the choke. The potential of the deflecting electrode is controllable through the key 22 and, relay 21. Specification 380,201 is referred to.
