Title: Improvements in and relating to electric discharge devices
IPC: H01J25/10
Filed: 1939-12-01
Abstract: 533,826. Cathode-ray tubes ; electron oscillators. BRITISH THOMSON-HOUSTON CO., Ltd. Dec. 1, 1939, No. 31223. Convention date, Dec. 1, 1938. Addition to 518,015. [Class 39 (i)] In a discharge device in which the electrons in a uniform cathode-ray are caused to gather into groups by velocity modulation as described in the parent Specification the electron stream is collected at a point where the velocity variation is substantially zero. The velocity modulation is effected by an electrode 33 enclosed in an electrode 30 with end walls 31, 31<SP>1</SP> oscillating potential being applied through co-axial leads 35, 36. When the velocity modulation has become density modulation the electrons pass through output electrodes 42, 43 and then through an electrode 24 to the collecting electrode 23. To render the velocity of the electrons as they strike the electrode 13 uniform the electrodes 23. 26 are connected to an oscillating circuit consisting of an outer electrode 51, the leads 50, 57 to the electrode 24, 23 and two condensers consisting of plates 54, 58 sliding in the leads 50, 57 and insulated from each other and a plate 53 sliding in the electrode 50. In a modification the velocity modulation is abolished by a pair of electrodes similar to 42, 43 connected to an oscillatory circuit.

Abstract: 618,112. Dry shavers. NAAMLOOZE VENNOOTSCHAP PHILIPS' GLOEILAMPENFABRIEKEN. Oct. 21, 1946, No. 31236. Convention date, Feb. 16, 1943. [Class 131] In a dry shaver the cutting plate provided with slits is provided with a ball bearing having races set at an angle such that thrusts both normal to the plate and in the plane of the plate are taken up by the ball bearing. As shown the cutting plate 1 having slits therein is mounted on the casing 14 by means of a ball bearing which comprises four ball races 5 ... 8 arranged, in the case of a rotatable or oscillatable cutting plate, to resist forces applied both normal to the plate and radially thereto. Fig. 1 shows races of which the races 5, 6 are carried by the cutting plate 1, race 7 by a ring 9 and race 8 by a plate 10 which is adjustable to take up play. In Fig. 2 the races 5 ... 8 are arranged at an angle # to the plane of the cutting plate which is less than that of a right angle, the race 8 being carried by an annular member 10 with upward flange the member being secured to the casing 14 by a nut 13. In the case of a reciprocating cutting plate the thrust of the cutting plate in its own plane is taken up by the bearing only in the direction normal to the reciprocation. The ball bearing may form a unit either with the cutting plate or with the holder.

Title: Improvements in or relating to the operating and controlling mechanism of cranes
IPC: B66C13/18
Filed: 1947-11-26
Abstract: 631,647. Jib cranes. HYLAND, Ltd., and CLARK, H. R. Nov. 26, 1947, No. 31262. [Class 78 (iv)] A hydraulically operated crane has a remote pump or pumps which supply fluid under pressure to a hydraulically driven winch for the lifting rope and to a hydraulically operated sluicing motor. As shown a platform 6 is supported on a circular track 7 on a fixed housing 8 to rotate with a vertical pillar 1 mounted on a footstep bearing 2 and provided with a rotary oil coupling 3. Pressure fluid from a remote pump or pumps is led by pipes 4 to the coupling 3, through passages in the pillar 1 and through pipes 5 to a slucing motor 11 and to a hydraulically operated winch 19. The slucing motor 11 is controlled by manually operated valves on the platform 6 and carries a pinion 10 meshing with a fixed internally toothed ring gear. Brake bands 14 pivoted at 15 to the platform 6 are hydraulically operated through a linkage 16 to grip the outer surface of the fixed ring gear when the motor 11 is not operated, so holding the platform 6 stationary. A similar brake is provided to lock the winch 19 when required. The winding rope 21 passes from the winch 19 over a pulley 22 at the top of the central pillar 1 to the pulley (not shown) at the end of the jib 23 which is stayed by means of a rope or rod 26.

Title: Improvements in or relating to the testing of gas mantles and other articles or materials
IPC: F21H3/00
Filed: 1920-11-04
Abstract: 176,442. Robin, J. T. Nov. 4, 1920. Testing physical qualities of materials.-Comprises a method of and means for testing gas mantles or other fragile articles wherein the upper end of the mantle is held while the lower end is immersed in a substance, for instance wax, which is cable of changing from a liquid to a solid form, the wax solidifying around the end of the mantle and thus affording a connection by which a gradually increasing tensile stress may be applied to the mantle. The mantle F is hung by the usual loop from an adjustable hook F', the lower end of the mantle dipping into wax contained in a pan D carried by a float C immersed in liquid in a tube A, which communicates with a glass tube A', the height of liquid in the tube being indicated by a scale A<2>. A liquid-container B communicates by a flexible tube B<1> with the tube A through a two-way cock B<3>, while the lower end of the float is guided at C' and is fitted with a dished rubber valve C<1>. In use, the container B is placed upon the upper shelf B<4> and the cock B<3> opened to allow liquid to pass into the tube A until full or nearly full, when the cock is closed. The burner E is lit and the collodion burnt off, the mantle being adjusted so that the lower end dips into the melted wax when the burner is extinguished. The container B is now placed on a shelf below the tube A and the cock opened. The unbalanced weight of the float as the liquid leaves the tube acts on the mantle and when fracture takes place, the float falls and the valve C<1> closes the outlet. The height of liquid in the tube indicates the fall when fracture takes place. The device may be used to test mantles up to a predetermined tensile stress. An adapter is used for enabling inverted mantles to be similarly tested. In a further modification several tubes are mounted side by side on the table each communicating with a compartment of a tank which is subdivided and is raised and lowered. Each apparatus is independent, but the cocks are conjointly controlled .

The Specification as open to inspection under Sect. 91 (3) (a) comprises also the production of acid wool dyes by causing a sulphonic, nitrosulphonic, aminosulphonic or sulphamic acid of naphthalic anhydride to react with ammonia or any aliphatic or aromatic amine, or by treating naphthalic anhydride or its derivatives with sulphonated amines. In further examples, (1) 4- amino-1 : 8-naphthalimide is treated with chlorsulphonic acid and pyridine, the sulphamic acid obtained dyes wool from an acetic acid bath in clear yellow tints, (2) 4-amino-1: 8-naphthalphenylimide is treated with chlorsulphonic acid and pyridine, the product dyes wool bright yellow tints; similar dyestuffs are obtained from 4-amino- 1 : 8 - naphthalethylimide and 3 - amino - 1 : 8 - naphthalmethylimide, (3) 4-amino-1 : 8-naphthalic anhydride is boiled with water and sodium 4- toluidine-3-sulphonate, the product dyes animal fibre in a clear yellow tint, and (4) 4-aminosulpho-1 : 8-naphthalic anhydride is boiled with water and p-toluidine; the product, which gives a clear yellow solution with a strong greenish fluorescence in water, dyes animal fibres in an acid bath a greenish-yellow tint of great clearness. This subject-matter does not appear in the Specification as accepted.
