Title: Improvements in or relating to resinous condensation products
IPC: C08G12/42
Filed: 1937-01-07
Abstract: Urea (including alkyl-, acyl- and aryl-ureas, thiourea, guanidine and substituted guanidine), formaldehyde and more than one molecular proportion of a primary aliphatic four-carbon alcohol (such as butyl and iso-butyl alcohol) for each molecular proportion of urea are condensed, the water formed in the reaction being removed by distillation until substantially two molecules of water for each molecule of urea are eliminated. Catalysts such as phthalic anhydride, maleic acid, adipic acid, citric acid, rosin, alkyd resins, hydrochloric acid, sulphuric acid, phosphoric acid, mercuric chloride, aluminium chloride or stannic chloride, iodine, bromine or benzoylperoxide may be used. Distillate other than water, separation of which may be facilitated by an entraining agent, is returned to the reaction. In examples: (1) a mixture of N-butyl alcohol, paraformaldehyde and caustic soda is warmed, mixed with phthalic anhydride, urea and toluene and the mixture heated and distilled, the distillate, less the water contained in it, being returned to yield a resin solution; (2) a mixture of aqueous formaldehyde, sodium acid phosphate and sufficient sodium hydroxide to yield a pH of 7,6 is mixed with urea and allowed to stand to obtain a crystalline methylol compound which is then mixed with isobutyl alcohol, toluene and phthalic anhydride and heated and distilled to yield a resin solution.  The products may be blended with other materials such as alkyd resins, oleo-resinous varnishes, cellulose derivative lacquers, oils, waxes, natural resins (congo, copal and Damar), plasticizers (dibutyl or dicyclohexyl phthalate, tricresyl or triphenyl phosphate, camphor, ethyl or butyl tartrate or lactate), pigments, dyes or fillers.  The products may be used as coating-compositions for metal, wood, glass, rubber, moulded plastic or synthetic resin products; to coat or impregnate fabric, woven fabrics of cotton, wool, silk and rayon, paper, leather, cellulose sheet (in the manufacture of shower curtains, glazed chintzes, raincoats and capes, tobacco pouches, glazed cambric for insulation, water-and greaseproof wrapping material, floor coverings and diaphragms); to impregnate and insulate electric coils; as an adhesive; and as a stiffening agent for felt or straw.  The Specification as open to inspection under Sect. 91 refers in general to the polymerization of a urea, an aldehyde and an alcohol.  This subject-matter does not appear in the Specification as accepted.

Title: Improvements in or relating to electrical plug and socket flash-lamp connectors
IPC: G03B15/04
Filed: 1955-01-07
Abstract: 772,854. Two-part couplings. HEIDECKE, R., and FRANKE, H., [trading as FRANKE & HEIDECKE FABRIK PHOTOGR PRAZISIONS-APPARATE]. Jan. 7, 1955 [Feb. 6, 1954], No. 547/55. Class 38 (1). [Also in Group XXXVII] The plug of a flash lamp connector comprises concentric pin-and-sleeve contacts 4, 5, respectively, which engage with corresponding sleeve contacts 10, 9 in a socket 11 mounted on the camera casing, the arms 14, 15 of a hairpin spring projecting through slots 12, 13 in the socket to snap behind a bead 7 on the plug to lock the connector parts together. The loop 16 of the spring is contained in a handle 17 and the plug is locked in two diametrically-opposed positions of the handle, i.e. when limbs 14, 15 engage in slots 13, 12 and in 12, 13 respectively, and the plug can be removed when handle 17 is in the intermediate position of Fig. 3. A disc 18 rotatable about socket 11 carries a portion 19 engaging the actuator 20 of an X-M flash, contact switch, shoulders 22, 23 on the handle 17 engaging a pin 21 on the disc 18 as handle 17 approaches either locking position, thus causing portion 19 to move actuator 20. Alternatively, the spring may be fixed and the socket rotatable and coupled to disc 18 or part 19. Specification 768,352 is referred to.

Title: Improvements in or relating to electric circuit breakers having arc-rupturing devices
IPC: H01H9/36
Filed: 1932-01-08
Abstract: 388,175. Arc-rupturing in switches. WESTINGHOUSE ELECTRIC & MANUFACTURING CO., East Pittsburg, U.S.A.- (Assignees of Johnson, F. B.; P.O. Box 91, Murrysville, Pennsylvania, U.S.A.) Jan. 8, 1932, No. 601. Convention date, Jan. 24, 1931. [Class 38 (v).] A " deion " circuit-breaker comprises a series of groups 43 of spaced conducting and insulating plates separated by blow-out coil sections 45 by means of which the arc drawn on opening the breaker is caused to split up and rotate until extinguished. The conducting plates 59 of copper in each group have extensions 63 provided with a slot 65 having a curved tip 67, the tips being all inclined in the same direction in one group. Slots 75 are provided to reduce eddy currents, these being oppositely directed in adjacent plates throughout the group. Surrounding each plate 59 and arranged to move the arc along the slot therein is a co-planar plate 61 of magnetic material having projections 76 for engagement by projections on the plate 59 to prevent the latter from buckling. The composite plates formed by plates 59, 61 are separated-from one another by insulating members 77, 79 of fish paper, which are shaped to provide an annular space 83 round which the arc rotates and into which the slots.67 lead tangentially. An opening 99 leads to a space 101 in which the arc gases are deionized by the large surfaces of the plates 59, 61. Each coil section 45 contains a coil 105 so connected between the endplates 109 as to cause the arc to rotate in opposite directions in adjacent sections 43, Fig. 1, the slots 67 being oppositely directed in adjacent sections to allow of this. Below each plate 109 is a spaced plate 111, Fig. 5, with a slot 115 and below the coils 105 are similarly-shaped metal plates 121 separated by fish-paper plates 125, the slots in which are slightly longer and less tapered than the slots 115. Endplates 131 at the ends of the complete stack are also slotted and connected in circuit by being soldered to the end of coil 105 on one side and on the other by contact with further plates 47, 49, the latter being connected with surfaces 31, 33 of fixed arc-horns 25, 27. The current path from the leads 39, 41 and through the horns is shown by the arrows at 35, 37, which current sets up a magnetic field to move the arc from the horns into the stack. The arc horns are, as shown in Fig. 2, formed of a series of spaced plates of magnetic material, arc gases being allowed to escape through the spaces in advance of the arc. The movement of the arc into the stack is assisted by the shape of the horns and by an arrangement of magnetic plates 137, separated by insulating plates 139 of similar shape, these being located below the plates 61 as extensions thereof and extending downwards, some to the arc horns and some to the arcing contacts, Fig. 1. Fibre plates 147 with heatresisting inserts 149 protect the plates 137 from the action of the arc. A pair of insulating sheets 153 with embedded tinfoil 155 constitutes a static shield.

Title: Improvements in or relating to cathode ray tubes
IPC: H01J29/34
Filed: 1955-01-10
Abstract: 766,083. Cathode-ray tubes. TELEFUNKEN GES. FUR DRAHTLOSE TELEGRAPHIE. Jan. 10, 1955 [Jan. 9, 1954], No. 653/55. Class 39(1). [Also in Group XL(c)] A method of forming a scale on the luminescent screen of a cathode-ray tube comprises operating the tube under such conditions as to cause the electron beam to burn the phosphor and deflecting the beam in such a manner that the parts of the screen scanned by the beam are discoloured permanently to form the desired scale. Since the same scanning means-coils or plates-are used for the burning as during normal operation, the scanning directions are automatically aligned with the scale, this alignment being difficult to achieve in prior art devices, .such as those with a scale outside the tube wall or formed on the inner wall of the tube by printing or etching before the luminescent material is applied. Further since the burnt area caused by the beam on a particular spot is less than the beam cross section it is possible to obtain fine markings. The scan during which burning is to take place is effected once slowly but can if desired be repeated a number of times. The luminescent material may be a sulphide or preferably zinc silicate and is activated by manganese, and the beam accelerating voltage may be less than 2 KV. to favour burning. The tube is used for measuring purposes.
