Title: Production of 1,3-cyclooctadiene
Inventor: NAGASE T
IPC: C07C5/25
Filed: 1971-10-18
Abstract: 1353498 1,3 Cyclooctadiene SUMITOMO CHEMICAL CO Ltd 18 Oct 1971 [20 Nov 1970 23 June 1971] 48290/71 Heading C5E 1,3 Cyclooctadiene is obtained by isomerizing 1,5 cyclooctadiene with a catalyst obtained by heating one or more alkali metals, one or more alkali metal hydroxides and an alumina or alumina-containing material at a temperature which is higher than the melting point of the alkali metal. The isomerization may be carried out in an inert hydrocarbon or ether solvent. The catalysts are preferably free of unreacted alkali metal. The cis-cis isomer of 1,3 cyclooctadiene is the predominant product.
Patent GB-1000772-A (GB)
Title: Decomposition of ammonia
Inventor: SHIPLEY DUDLEY KEITH
IPC: C01B21/02
Filed: 1962-12-21
Abstract: Ammonia is decomposed to nitrogen and hydrogen by passing it over a catalyst, consisting of nickel supported on alumina, maintained at 600-900 DEG  C., the alumina having before the application of nickel to it a specific surface of more than 20 m.2/gm.  The alumina may be made by heating alumina monohydrate or trihydrate at 500-1000 DEG  C. for 2 hours.  The catalyst support is desirably at least partly gamma alumina and may be converted to kappa during use, but not more than 20% of the alumina should be in the alpha form.  The nickel content of the catalyst may be up to 50% by weight.  The alumina hydrates may be made by seeding or carbonation of a sodium aluminate solution. The catalyst, which should be sulphur free (<0.5%) may be made by impregnating alumina with a sulphur-free nickel salt, especially nickel nitrate, then draining, drying and converting the salt to metallic nickel.  After the drying stage the impregnation may be repeated in order to increase the content of nickel salt.  In converting the salt to nickel the salt may be first decomposed to the oxide by heating, then reduced by hydrogen or ammonia.  The reduction is conveniently carried out in the catalyst chamber of the NH3 cracking plant.  Specification 768,091 is referred to.
Patent GB-1033060-A (GB)
Title: Improvements relating to weaving looms
IPC: D03D47/00
Filed: 1962-12-21
Abstract: Sufficient weft for two picks is drawn from a stationary bobbin and blown into a shuttle; or only part of it may be blown in, the remainder being trailed into the shed when the shuttle is picked. A weft measuring device is mounted on each end of the slay to feed an associated shuttle, which enters the top cell of a drop box at is replenishing end of the loom and the bottom cell at the other end. Measuring is effected by a conical drum driven by a clockwork motor which is continually rewound by the oscillations of the slay; the motor rapidly makes rather more than one revolution when tripped on arrival of the shuttle in the top cell of the drop box, the length of weft delivered being determined by gearing between the motor and the drum and being equal to two picks plus the distance between the nozzle and the selvedge.  When the first pick has been laid in the shed, the weft is cut at the selvedge and the end is drawn back to the mouth of the nozzle by turning the motor backwards by the amount that its forward rotation exceeded one revolution; to prevent the wrong weft from being cut, a guide thread operated by a heald raises the weft into contact with a fixed guide thread to bring it to the height of the cutter.  Air pressure is generated by bellows operated by a spring which is loaded by movement of the slay and tripped by arrival of the shuttle in the top cell of the box.  In a modification, the measuring devices are mounted on the fixed part of the loom.  The weft being blown into a flexible tube before arrival of the shuttle, and then blown into the shuttle by another nozzle on the end of the tube; the air pressure may pulsate to increase the tractive effort on the web; the nozzle for blowing the weft into the flexible tube may be omitted.

The length of fibres, e.g. those from which paper is made, is determined by suspending the fibres in a liquid which is passed at a constant rate through a conically converging-divering aperture, Fig. 1, across which a physical flux e.g. a light beam or electric field, is passed, variations in the flux, produced by the passage of the fibres through it, being detected to provide a measure of the length of the fibres. As described, using as the physical flux the electric field between electrodes 1, 2, to indicate those fibres having a length and diameter above predetermined values, the voltage across the electrode is supplied via amplifier 5, Fig. 3, to an amplitude limiting amplifier 6, an integrator 7, threshold circuit 8 and a counter 9, indicating the number of fibres having a length above the present length. The output from amplifier 5 is also supplied to a threshold circuit 10, impulse amplifier 11 and counter 12, indicating the number of fibres having a diameter above the preset diameter. The signals from amplifier 5 and circuit 8 may also be fed to an oscilloscope 13.

Title: Improvements in or relating to mine roof supports
Inventor: SEDDON JEFFREY WILLIAM
IPC: E21D23/00
Filed: 1965-11-17
Abstract: 1,105,723. Conveyers. GULLICK Ltd. 18 Oct., 1966 [17 Nov., 1965], No. 50051/65. Heading B8A. A self-advancing mine roof master support A comprising a rear unit 10 and a front unit 11 has an advancing hydraulic ram 14 incorporated in the base 12 of the rear unit 10 and connected to an anchorage in the form of a coal conveyer C through a universal joint 21 on the ram's piston rod 15 and a relay bar with a clevis 23 slidable along a rail 24 attached to, and extending longitudinally of, the conveyer C. A quick-acting clamping device 26, through a link 25, enables the clevis 23 to be clamped to the rail 24 after being adjusted therealong. The relay bar 22 extends through an arch or tunnel 16a of the base 16 of the front unit 11 and has lateral rearwardly tapering wings 22a. After the ram 14 has been extended to push or snake the conveyer C towards the coal-face observation is made (it being assumed that the coal face slopes from left to right looking at the coal face) to see if any objectionable down seam movement of the conveyer C has taken place. If some corresponding correction or up-seam (i.e. to the right as shown) movement of the support A is required, then clamping device 26 is released and the clevis 23 slid along the rail 24 by an appropriate amount and locked in its new position by the clamping device 26 (at this stage the wings 22a have been advanced out of the arch 16a). A guide bar 30 on the adjacent slave support B is correspondingly adjusted by an hydraulic device 32, clearance in a yoke 28 attached to the rear master support unit 10 allowing this, the guide bar 30 being pivoted at 30a to the slave rear unit 12 and to the device 32. Hydraulic props 13, 17 are lowered and ram 14 retracted to advance the support A towards the conveyer C. During the latter stages of this movement the front unit 11 centralizes slidably on the relay bar 22 by re-engagement of the wings 22a in the tunnel 16a. At the same time the rear unit 10 is repositioned by engagement of the yoke 28 with the guide bar 30. The support A is then re-secured by extending the props 13, 17. The slave supports B are then advanced in turn being similarly repositioned by roller followers 29, 29a engaging skids 27, 27a respectively on the front and rear units (in the case of the first slave unit B the means 27a, 29a are replaced by the means 28, 30). Instead of being infinitely adjustable along the rail 24 the clevis 23 may be attached at spaced points along the conveyer C.
