Title: Improvements in or relating to cathode ray tube and like electron beam apparatus
IPC: H01J29/62
Filed: 1934-02-06
Abstract: 426,087. Cathode-ray tubes. TELEFUNKEN GES. FUR DRAHTLOSE TELEGRAPHIE, 12, Hallesches Ufer, Berlin. Feb. 6, 1934, Nos. 3936 and 3937. Convention dates, Feb. 6, 1933 and July 31, 1933. [Class 39 (i)] An electron lens comprises two or more elongated conductive hollow bodies coaxial with respect to the electron beam axis and means for applying potentials to the bodies, the potentials being such that the potential gradient is reversed at some point along the path of the beam, and the apertures in the bodies being so large that only the lines of force commencing on the internal walls of the bodies produce a lens effect. The bodies may be of circular, elliptical or rectangular cross-section. In one form, Fig. 4, an anode consists of a diaphragm 5 and a net or mesh cylinder 6 which surrounds a cylinder 7, the members 6 and 7 constituting the electron lens. The remainder of the tube other than the screen 2 is coated with a silver layer 9 connected to the anode. In a modification, the cylinder 6 is replaced by a coating on the wall, and the cylinder 7 by another coating between the coatings 6 and 9 and maintained at a negative potential relative to them. The coatings may be replaced by tubes or nets, or one or more of them may form part of the tube envelope. The negatively biassed cylinder may have the modulating or cutting - off potential applied to it, the potential of the Wehnelt cylinder then remaining constant. In another modification two short bodies may be arranged inside a long body. Fig. 6 shows an arrangement which prevents " chromatic " aberration due to the presence of rays of different hardness and " spherical " aberration due to the large cross-section of the rays. The hollow bodies 10... 19 are connected to tappings on a potentiometer 20 which has a positive pole connected to its mid-point and a negative pole to its ends. If a divergent lens is required these potentials are reversed. In a modification the elements 10 ... 19 are replaced by the turns of a resistance helix furnished with suitable tappings.

Title: Improvements in steam raising systems
Inventor: HARTLEY DONALD EDWARD
IPC: F22B29/06
Filed: 1959-02-04
Abstract: 912,710. Heating steam boilers by hot gases. SUPERHEATER CO. Ltd. March 11, 1960 [Feb. 4, 1959], No. 4005/59. Class 123 (2). A once-through steam boiler heated for example by the coolant gas of a nuclear reactor, comprises a cylindrical casing 5 in which is coaxially-disposed a tubular baffle 4, the tubular heating surfaces of the boiler being located in the annular space around the baffle 4. The heating surfaces consist of parallel-connected, concentric helical coils of tubing 10 ... 12. To compensate for the increasing length of the outer coils 11, 12 which would otherwise reduce the water-steam flow therethrough, the bore of the tubing of these coils is successively increased so that the temperature of the working fluid discharging from all the coils is the same. In a modification, Fig. 1, not shown, uniform heat input rates are obtained by varying the radial pitches of coils which are formed of tubing of the same bore so that they decrease progressively from the inner tube to the outer tube, increased heat transfer rates occurring at the inner coils which are of shorter length due to increased gas velocity thereover.

Patent GB-1076051-A (GB)
Title: Polymers capable of self-curing at room temperature
IPC: C08F218/08
Filed: 1965-02-02
Abstract: Polymers capable of self-curing at room temperature are prepared by heating together at temperatures up to 90 DEG  C., in the presence of an addition polymerization catalyst, a mixture consisting of a monoethylenically unsaturated compound free from groups which react with the glycidyl epoxy group, a glycidyl ester of an ethylenically unsaturated carboxylic acid, and a monoethylenically unsaturated compound containing a group which reacts with the glycidyl epoxy group, the latter two compounds being present in quantities such that the numerical product of their mole-per cent concentrations in said mixture lies within the range of 10 to 30, said concentrations being at least 1 mole-per cent for the minor component and not more than about 20 mole-per cent for the two components added together; the major portion of the last two components being added to the polymerization mixture in gradual manner after the polymerization has begun.  Monomers of the first mentioned type above include esters of acrylic, methacrylic or haloacrylic acid, vinyl and vinylidene halides, vinyl aryl compounds, and vinyl esters.  The second type of monomer may be, for example, the glycidyl ester of acrylic, methacrylic or crotonic acid, or of methyl hydrogen maleate.  The third mentioned monomer may be a carboxylic acid such as acrylic, methacrylic, crotonic or itaconic acid or methyl hydrogen maleate, or a compound containing an amino, amido, hydroxyl or mercapto group, e.g. acrylamide and hydroxyethyl methacrylate.  Suitable polymerization catalysts include peroxides, peroxy esters, persulphates and azo compounds, e.g. benzoyl peroxide, t-butyl perbenzoate, potassium persulphate, azodiisobutyronitrile, dimethyl azobisisobutyrate and azo-bis-(a -methyl capronitrile). Polymerization can be effected essentially in bulk, although small amounts of solvent may be employed during the gradual addition of monomers.  The curing of the polymers can be improved by incorporating therein titanium-containing amine compounds, e.g. triethanolamine titanate, or esters of titanic acid; curing can also be accelerated by heating.  Coating and adhesive compositions can be obtained by dissolving the polymers in solvents, e.g. alkyl or alkoxyalkyl alcohols, ketones, ethyl acetate, hexane, toluene, carbon tetrachloride, trichloroethane and mixtures thereof.  In an example, the preparation of a vinyl acetate-glycidyl methacrylate-acrylic acid terpolymer is illustrated.

The cylinder E<1> is carried by a platen E<2> slidable on the rods B<4> on the other side of the bridgepiece, being normally held against the bridgepiece by gravity or by a spring. The tension rods are operated through compression springs B<5> from eccentrics B<3> on a shaft B<2> driven through a clutch Bx by gearing from a drive shaft A<1>. The plunger F is operated through a spring F<2> from an eccentric F' on a gear wheel B<1> driven by the shaft B<2> through a clutch B<1x>. The clutch Bx operates for half a revolution of the shaft B<2> and the clutch B<1x> for a complete revolution, the clutches being operated from rods G<1>. G<2> through mechanisms interconnected so that the plunger cannot be operated when the mould is open. In operation the clutch Bx is actuated to draw the rods B<4> to close the mould parts together against the nozzle E. A feeding hopper E<1x> is filled with material and then the clutch B<1x> is actuated to move the plunger F down to inject the material into the mould and then withdraw the plunger, the tension rods and springs meanwhile maintaining the mould closed. The clutch B<x> is then again actuated to open the mould. The descent of the plunger can be adjusted by a micrometer screw device F<3>. The position of the platen C on the rods can be adjusted by worm gearing so as to accommodate different moulds. The movement of the platen D is limited by headed studs ax. The hopper E<1>w may be filled from a shoot H<5>, Fig. 5, supplied from a hopper H<4> by an intermittently operated rotary drum H having radial division plates H<1> or by a continuously or intermittently operated Archimedean screw or worm. The rotary drum may be driven by a pawl and ratchet device from a rod H<6> having tappets H', H<8> adapted be engaged by an arm F<4> on the plunger F. If there is sufficient material in the hopper E<1x>, the plunger does not move down far enough for engagement with the tappet H<8> and no feed of the drum takes place, so that material is fed only when required.
