Convention date, Oct. 21, 1932. [Class 39 (i)] In a Braun tube for television, the cathode comprises an indirectly heated, metal body 3 with a recess 11 at the centre of its front face filled with emissive material and accurately centred in the control cylinder or electrode 1 by an interposed spacer 2. The electrode 1 is accurately centred with respect to the electrode system which is so arranged that all normals to the emissive area 11 lie within the "aperture " of the electronoptical system, i.e. are not inclined to the axis of the system by more than a certain angle such as 10‹ so that no halo of light is formed about the light spot on the picture screen. The accurate centring of the emissive area avoids the " lateral pull " defect of movements of the light spot on variation of the control voltage on the electrode 1. In making the cathode, a rectangular recess 5-1 mm. by 1.5-3 mm. is engraved or milled in the body 3 in a direction perpendicular to the direction of the lines of the picture and is filled with emissive substance, the concave face of the body 3 being finally polished so that the emissive substance has the same curvature as the face of the body 3 and is confined to the area 11. The curvature of the emissive area may be equal to or greater than that of the "level line dark" as described in Specification 420,667. The emissive area may be circular instead of rectangular. The electrode system may include a first anode, a second cylinder negative with respect thereto and a second anode. The heater leads pass through insulating tubes 4, 5.

IPC: B22D17/06
Filed: 1919-11-25
Abstract: 135,849. Gullborg (formerly Goldberg), J. S. Oct. 8, 1915, [Convention date]. Casting-machines; metal-pouring; moulds; clamping moulds; castings, extracting. - In a die-casting machine the various parts are automatically operated from a cam-shaft 25 and the machine stopped at the completion of a cycle of operations. Means are provided for raising and lowering the mouth of the pivoted melting-pot 57, for controlling the air pressure supply to the mould feeding passage 58, opening and closing the dies 26, 27, inserting and removing the cores, and raising and lowering the protecting shield 89. The melting-pot 57 is pivoted at 61, and its mouthpiece 62 is pressed against the mould passage by the adjustable link 80 and cam-operated lever 75. The U-shaped feed passage 58 is situ. ated in the hottest part of the melting-pot, and is fed therefrom through a spring-closed valve 65, which is opened when the melting-pot is lowered, by a stop 81 engaging nuts 67 on the valve stem. The mould is kept hot by a casing 55 and gas burners 82, 83. The air supply to the feed passage 58 is through a jointed tube in line with the pivot 61, and is controlled by a slide valve operated partly by a cam on the shaft 25, which cam causes the admission of compressed air, and partly by a cam on the shield 89, which opens the exhaust when the shield is raised, and prevents air being fed to the passage 58 at such time. The die-part 26 is clamped by a screw 29 in a fixed part 21 of the frame, and the movable part 27 by a screw 31 in a slide 33 moved to open and close the dies by a cam-operated toggle mechanism 45, 46. Cores 137 mounted on cross slides 134 are inserted and withdrawn by levers 138 operated by shafts 140 having cam levers 149 engaging cams 52. As the die-part 27 recedes from the part 36, an adjustable ejector rod 36 with stripping pins 35 is actuated by a stop 39 to strip the casting.

Filed: 1950-12-01
Abstract: 700,413. Finishing fabrics. BLEACHERS' ASSOCIATION, Ltd., and MELVILLE, A. Nov. 28, 1951 [Dec. 1, 1950], No. 29417/50. Class 42 (1) Fabrics are treated by compressively shrinking the selvedge portions only, leaving the remainder unshrunk, and then subjecting them across their whole width to weft-wise tension on a stenter. " Compressively shrinking " is defined as shrinking in length by the application of lengthwise compression and superficial restraint. Independent compressive shrinking heads may be supported on brackets 18 bolted to each of the chain frames 16 of a stenter, the distance between the frames 16 being adjustable. Each shrinking head comprises a bearing support 19, in a sleeve in which is journalled the spindle 21 of a roller 20. A second roller 23 is mounted on a spindle 24 which is journalled in a bearing block 25 slidablv mounted in a slot 19d in the support 19, and adjustable by a nut 28. A belt 29 of rubber, felt or other suitable material passes around the rollers 20 and 23, and an upper roller 30, the spindle 31 of which is journalled in a bearing block 32, which slides in a slot 19e in the plate 19, and is adjustable by a handwheel 33, presses against the upper portion of the belt 29. The roller 30 is caused to rotate bv a chain drive from an electric motor 36. The selvedges of the fabric 45 are fed between the belt 29 and roller 30 and then, after passing over a roller 40, which extends the whole width of the fabric, are engaged by the clips 13 of the stenter chains. Electrical means are provided for synchronizing the speeds of the motors 36, which may, however, also be varied to effect weft straightening. The degree of compressive shrinking applied to the selvedges may be adjusted independently by the handwheels 33. Steam or water may be applied to the fabric to assist shrinking, while undergoing weftwise tension on the stenter, and the fabric may be damped, impregnated with chemicals or dyestuffs or otherwise treated before being passed to the shrinking heads. Specifications 359,759, 371,976, 372,803 and 529,579 are referred to.

Abstract: 802,351. Hypodermic injection appliances. HABER, C. Oct. 13, 1954 [Oct. 14, 1953; Sept. 11, 1954], No. 29563/54. Class 81 (2). The needle of a hypodermic syringe is moved sideways to and from its operative position on the syringe to avoid sucking back contained fluid, and is held in position by a spring-loaded lever. An attachment for fitting to the taper of an ordinary syringe comprises a body part 1 carrying a bell-crank 2 which is spring-loaded by a leafspring 4 so as to bear down, at its bifurcated end 15, on the flat base 8 of the needle mount, so that this is held in liquid-tight contact with a complementary insert 9. Locating studs are provided to ensure correct alignment of the bores. It is intended that the needles shall be stored horizontally after sterilization and, by compressing the spring 4, by thumb pressure on the lever 2, the needle can be placed in position and withdrawn from its holder without being touched. A spring 5 is provided to exert a lateral thrust to eject a used needle as soon as the pressure of the bellcrank is removed. As a further safeguard against contamination it is proposed to prevent unintentional retraction of the syringe plunger by providing a dished, split disc around the plunger stem, held in the end cap of the syringe, so as to allow only inward movement. A lever is provided to bend the disc inward when it is necessary to retract the plunger. The Specification also describes a complete syringe in which the needle retaining device and its mounting are formed as integral parts thereof.
