Abstract: 501,042. Optical sound - recording. RADIO CORPORATION OF AMERICA. May 19, 1937, No. 13954. Convention date, June 27, 1936. [Class 40 (ii)] Tracks for masking both sides of bilateral sound records for "ground noise reduction are produced by the modulation at sound frequency of two sides of a beam of light having a thickness of not less than one wave length of the lowest frequency. As shown in Fig. 1, light from a lamp 10 passes through three apertures 13A, 13B, 13C in a mask 12, and is thrown by galvanometer 15 through slits 19, 19<1> on to the film 20. The triangular aperture 13A co-operates with the narrow slit 19 to produce a bilateral sound record, while the apertures 13B, 13C, having only one side inclined, co-operate with the thick slit 191 to produce masking tracks. The several tracks are subsequently printed in correct relation to produce the finished positive record, Fig. 4.

Abstract: 881,559. Discharge tubes; thermonuclear apparatus. COMPAGNIE GENERALE DE TELEGRAPHIE SANS FIL. April 26, 1960 [May 4, 1959], No. 14544/60. Drawings to Specification. Classes 39(1) and 39(4) A charged particle confinement device comprises an evacuated vessel constituted by two portions in communication with each other through a cavity resonator, means for injecting ions and electrons into the vessel, means for producing a static magnetic field directed along the longitudinal axis of the vessel and having a region of minimum strength located between regions of maximum strength, and means for inducing ultra-high frequency electromagnetic oscillations in the cavity resonator. The vessel may comprise two cylindrical tubes joined to either side of a cavity resonator of elliptical cross-section. An ion gun and an electron gun are mounted at the ends of the tubes and the tubes are surrounded by coils arranged to produce strong reflecting magnetic fields near the ends of the tubes decreasing steadily to a weaker field in the resonator. The resonator is preferably tuned to the cyclotron frequency of either the electrons or the ions and is excited at that frequency by an R.F. source connected to a probe projecting into the resonator. By suitable design of the magnetic field it can be arranged that particles gain energy each time they are reflected through the resonator by the magnetic reflector fields. If the electrons are energised this produces conditions favourable for inducing and maintaining oscillations of the plasma, and the device may be used as an oscillation generator. If the ions are energised this produces conditions fovourable for the production of energy by thermonuclear fusion.

Abstract: 996,153. Knitting-machines. NAGATA SEIKI CO. Ltd. April 16, 1962 [April 15, 1961; June 12, 1961], No. 14548/62. Heading D1C. The length of fabric produced by a knitting- machine is controlled by detecting, by photoelectric means, the leading edge of the fabric before it reaches its final length, and using the signal from these means to vary the length if necessary. A circular knitting machine has a transparent tube 9 through which the stocking being produced is drawn pneumatically between two light sources 10, 11, and their corresponding photo-cells 12, 13. The sources are energized by a cam operated switch 18 when the stocking edge should have reached level A. If the stocking is short, cell 12 emits a signal; if the stocking is too long the cell 13 is obscured. The signal or lack of signal to amplifier 19 causes energization of the appropriate solenoid 20, 21 to rotate screw 6 to respectively lower or raise the needle cylinder to decrease or increase the stitch density. In another embodiment the holder 14,15 for the sources and cells is arranged to rotate and descend as the stocking is produced, the photo-electric means thus traversing a helical path to scan the fabric continuously or intermittently and produce a more regular course spacing.

Title: Stranded conductor production process
IPC: H01B13/02
Filed: 1971-05-13
Abstract: 1353188 Stranding machines OKI DENSEN KK 13 May 1971 [13 May 1970] 14724/71 Heading D1T [Also in Division H1] An apparatus for producing a stranded conductor may be used in either the paying out or the taking up fashion. In Fig. 1, which depicts the apparatus taking up a stranded conductor 2, strands 1 are fed by a capstan 6 through a stationary guide plate 7 and a rotary twisting member 8. The conductor is then wound onto a flanged reel 18 via pulleys 20 mounted on a rotatable ring 19. The reel 18 is detachably mounted on a hollow shaft 16 cantilevered at one end by a pedestal 32 and the ring 19 is supported by four rolls 24-27 mounted on a pedestal 30. A detachable flyer 13, which prevents contact between the conductor 2. and the adjacent flange of the reel 18, is mounted on a shaft 15 inside the shaft 16. The flyer may also assist in rotating the conductors. An electric motor drives the main drive shaft 12 which rotates the capstan 6, the twisting member 8 and the shafts 15, 16. A torque motor 35 rotates the ring 19. In order to wind the conductor on the reel 18, the ring 19 is rotated at a different rate from the reel. When the rate of rotation of the ring is to be slower than that of the reel the torque motor may be replaced by a brake and the tension in the stranded conductor causes the ring to rotate. A reversible motor 34 moves the ring 19 along its longitudinal axis so that the conductor is wound uniformly along the reel, and, as the diameter of the reel together with the wound conductor increases, the pitch of the conductor also increases. When paying out, the apparatus has separate conductors, 2-5 Fig. 2, wound around the reel 18 and these are passed around pulleys 20-23 and then through the twisting member 8. In the embodiment of Fig. 4, not shown, the torque motor is omitted and the ring 19 is rotated by the main drive shaft 12. In a further embodiment, Fig. 5 not shown, the reel 18 is rotated by the torque motor 35 and the ring 19 is rotated by an electric motor (46) via the main drive shaft 12, the relative rate of rotation between the ring and the reel being varied so as to produce a stranded conductor with constant pitch.

Abstract: 571,143. Catalytic conversion of hydrocarbon oils. UNIVERSAL OIL PRODUCTS CO. Oct. 22, 1942, No. 14840. Convention date, Oct. 27, 1941. [Classes 1 (i), 32, and 91] In processes for the catalytic cracking, dehydrogenation, or desulphurisation of hydrocarbons of the kind in which the suspension of catalyst and hydrocarbon vapors is maintained in a 'dense phase' in the lower portion and in a 'dilute phase' in the upper portion of the conversion and regeneration zone respectively, the catalyst is continuously circulated in a dense phase through the zones by conducting it from a point below the surface of the dense phase in each zone to a point below the surface of the dense phase in the other zones, the flow of catalyst being promoted by maintaining the catalyst under a higher pressure in one zone than in the second zone and by introducing gases or vapors into the conduit between the second zone and the first zone. The hydrocarbon stock is fed through line 1 and mixed with solid contact powder fed through line 3 is injected upwardly into the reactor 30 where a dense phase is maintained below the level of line 11 and a less dense phase above that level. The gaseous reaction products with a small amount of contact agents in suspension therein pass off through line 5 to a separator 6 where the contact material is separated and returned to the dense phase through line 7. Constituents of the dense phase are continually removed through line 10 and mixed with an oxidising gas in line 15 through the injector action of which the dense phase is conveyed to a second similar reactor 29 where the contact agent is regenerated. From the reactor 29 gazeous products are removed through line 20 and separator 21 while the regenerated catalyst is recycled through line 25 to the reactor 30. A further supply of gases is injected through line 18 to maintain the solids in suspension. Flow of suspension through line 25 is maintained by operating the reactor 29 at a higher pressure than the reactor 30 the pressure being regulated by an electrical control 28 controlling valves 9, 24 in the draw off pipes 8, 23. In the modification, Fig. 2 (not shown), the contacting zones are inclined so as to permit the use of straight vertical transfer lines for the catalyst.
