Abstract: 391,006. Cathode-ray tubes. BRITISH THOMSON-HOUSTON CO., Ltd., Crown House, Aldwych, London.-(Assignees of Coolidge, W. D. ; 1480, Lenox Road, Schenectady, New York, U.S.A.) Aug. 18, 1932, No. 23211. Convention date, Aug. 18, 1931. [Class 39 (i).] Apparatus for recording electrical variations, either of a continuous character, such as audio current variations, or of short duration, comprise a cathode ray tube on which the variations are impressed and which emits rays through a slit on to a sensitized member as it is guided through a chamber exhausted of air or supplied with a low-density gas such as hydrogen. The anode is earthed and provision is made for deflecting the emitted rays accurately on to the slit. As shown, the tube is constructed with a part 3 sealed into the part 1 to constitute the anode, and the cathode comprises a straight, or small diameter coil, filament mounted in a truncated rectangular pyramid 2 and heated by a battery 6 through a rheostat 7. The operating voltage for the tube is supplied through a step-up transformer 4 and detector 5, and after modulation by the electrical variations through a transformer 12 is fed to an amplifier 9 and impressed on the cathode circuit. The rays emitted by the tube pass through a Lenard window comprising a slit in the end of the anode 3 and in a covering 27 of foil, such as aluminium foil, and fall on a film 15 guided through a chamber 16 which is exhausted or fed with hydrogen through a pipe 19. An adjustable magnet 32 acts on the rays so that they fall directly on the window. Reference has been directed by the Comptroller to Specifications 334,576, [Class 39 (i), Electric lamps, Arc &c.], and 377,272.

Title: Improvements in re-inking means for the ribbons of typewriting machines
IPC: B41J31/16
Filed: 1919-09-23
Abstract: 152,189. Simpson, J. E. Sept. 23, 1919. Ink-ribbon mechanism.-The ink ribbon receives ink or moisture from a roller at each operation of the keys. The device shown in Figs. 1 and 2 is attached to a type-lever machine, and comprises a bracket 10 which is secured by a screw to the segment 4 and is formed with a fork 12, 13 for engaging one of the type-alining jaws 3. An inking-roller 18 is mounted on a pin 16 supported by a plate 14 which is pivoted at 15 to an arm 9 of the bracket. The ink ribbon 8 passes through a guide 24 on the arm 9 and also passes in front of a finger 27a formed on a link 27 which is connected to a dog 30 pivoted on the fork 12 and normally projecting into the space between the alining-jaws 3. The roller is normally close to the finger 27<a>, and at each operation of the keys, one of the type levers 5 rocks the dog 30 and causes the finger 27a to move the ink ribbon into contact with the roller. The finger and the associated parts are restored to the normal position by the tension of the ink ribbon. When it is desired to prevent the ink ribbon from moving into contact with the roller, the plate 13 is rocked by a fingerpiece 33 and the roller is thereby moved away from the ink ribbon. The plate is retained in the set position by means of projections and recesses 21 in the plate and the arm 9, and the movements of the plate are limited by the engagement of a lug on the plate with the edges of an aperture in the arm. When the plate is rocked, the lug engages a bend 32 in the link 27 and moves the dog 30 out of the path of the type-levers. The arm 9 is provided with a finger 25 for preventing accidental contact of the ink ribbon and the roller. The roller rests on a collar 17 on the pin 16 and is retained by a disk 23 which is screwed on the pin.

Title: Improvements in or relating to apparatus for facilitating the unwinding of threads from bobbins and like packages
IPC: D01H7/86
Filed: 1931-08-20
Abstract: 388,078. Tensioning thread during unwinding. BRITISH CELANESE, Ltd., 22, Hanover Square, London, POOL, W. and LATHAM, L., c/o British Celanese, Spondon, near Derby. Aug. 20, 1931, No. 23496. [Class 120 (ii).] Thread-tensioning means for use in the over end unwinding of thread packages comprises guide means constraining the thread to pass through a point which follows a circular path about the axis of the package, and yielding means which, prior to the engagement of the thread by said guide means tend to draw the thread substantially radially towards the axis of the package to a degree depending on the tension in the thread. The invention is described in connection with a double-twist device of the type described in Specification 369,293. A rotating spindle 8 with a whorl 9 is mounted in bearings 10 and separated by ball bearings 7 from a tube 6 which carries the stationary thread package 5. Rollers 11 mounted in an enlarged portion 12 of the spindle 8 have flanges 13, 14 which engage races 15, 16 to keep the package 5 stationary. A tube 22 fitting into blocks 23 in the tube 6 and supported by a spring 24 carries an annular member 25, supporting a brass disc 26, with a burnished edge, and in an annular groove a light ring 27 carrying a spiral spring 28 terminating in an eye 29. The thread 30 passes over a burnished cap 20 on the bobbin, through the eye 29 over the edge of the disc 26, down the tube 22 to an exit 32 and thence in the form of a rotating balloon 33 to a guide eye 34. The spring 28 which preferably makes one-half to one complete turn about the axis of the package compensates for variation in the tension of the thread as it unwinds. The disc 26 may be freely rotatable and may have a ball bearing mounting. The cap 20 may be replaced by a disc similar to the disc 26 and mounted below the spring 28 and if desired a further disc and a further spring may be mounted above the disc 26. The disc 26 may be replaced by a rotatable guide eye.

Title: Method for converting scrap metal into sinterable powder
IPC: B02C17/18
Filed: 1976-06-10
Abstract: 1508941 Sintering powder produced from scrap metal FORD MOTOR CO Ltd 10 June 1976 [3 Dec 1975] 24014/76 Heading C7D [Also in Division B3]  A method of making a metal powder which can be compacted and sintered from scrap metal, comprises taking scrap metal particles 10 having a surface to volume ratio of at least 60:1, and reducing its temperature to below the ductilebrittle transition temperature and simultaneously shattering particles 10 and coating them with a protective metal by impact, the protective metal having a melting temperature below but substantially about the liquidus of particles 10 and being completely soluble in the metal of particles 10, the protective metal being readily abraded. The  impact is with protective metal particles 17, of copper, in a ball mill 12, and the cryogenic temperature is obtained by liquid nitrogen 15, poured in through pipe 18. As ball-mill 12 is rotated, particles 10 are at the cryogenic temperature whilst in the liquid nitrogen 15 and are shattered as they encounter copper balls 17, and as the mill 12 rotates, for part of the time the particles 10 and 17 are out of the liquid and above the ductilebrittle transition temperature but below ambient with the result that the powder particles 10 are work-hardened. The process may be a continuous one, using a ball mill as in Fig. 3 (not shown) which is tilted at 1 or 2 degrees from the horizontal so that as the mill rotates the powder works its way down to one end where it is continuously extracted. After the powder has been formed it may be compacted into a shape and sintered. Particles 10 may be ferrous, in which case the sintering temperature is 2000-2100F.
