Title: Improvements in or relating to the catalytic isomerization of hydrocarbons
IPC: C10G45/60
Filed: 1961-09-07
Abstract: In the isomerization of olefins as described in the parent Specification there is added to the feed a sulphur-containing petroleum which is simultaneously desulphurized.  The reaction is effected at 100 DEG -500 DEG C., 10-100 atmospheres and 0,5-20 vol./vol./hr. over a solid acidic catalyst carrying one or more sulphides, selenides, tellurides, antimonides and/or arsenides of a Group VI and/or VIII metal.  The petroleum fraction may boil in the range 0 DEG -250 DEG C. and contain 0,01-0,5% sulphur.  If of different boiling range from the olefinic feed, it may be separated from the product by fractional distillation or condensation.ALSO:In the production of branched chain hydrocarbons as in the parent Specification in which a feed containing unbranched or sparsely branched olefins is contacted at elevated temperature and pressure with hydrogen and a solid acidic isomerisation catalyst carrying one or more sulphides, selenides, tellurides, antimonides and/or arsenides of Group VIa and/or Group VIII metals, there is added to the feed sulphur or a compound thereof which is vaporizable and readily decomposed under the reaction conditions.  Suitable compounds of sulphur are hydrogen sulphide, alkyl mercaptans, dialkyl sulphides and dialkyl disulphides, the amount of sulphur added being 0.001-1% by weight of the feed.  In a preferred form there is added a petroleum fraction containing 0.01-0.5% sulphur and boiling in the range 0-250 DEG C., preferably in an amount such that the weight ratio to olefinic feed is 0.005-0.1 times the difference between the bromine numbers of the olefinic feed and the fraction.  Preferably this fraction is heated to 10-100 DEG C. above the reaction starting temperature and the olefinic feed heated by mixing.  The fraction is simultaneously desulphurised and, if of different boiling range from the olefinic feed, may be separated from the product by fractional distillation or condensation and subjected to reforming. Alternatively the mixed product may be used as such as a motor fuel. The olefinic feed may be a gasoline obtained by thermal reforming or thermal or catalytic cracking and is treated at 100-500 DEG C., 10-100 atmospheres and 0.5-20 vol./vol./hr.  The product is generally saturated, and specific olefins may be converted to products having a different number of carbon atoms.

Filed: 1974-07-29
Abstract: 1449571 Free spool fishing reel SHAKESPEARE CO 29 July 1974 [14 Sept 1973] 33320/74 Heading A1A A fishing reel has a spool 12 manuallyrotatable by a crank; a gear 39 and a pinion 28 which is clutched to the spool shaft 24 upon commencement of crank rewinding, by clutch elements 29, 30. To cast the line the clutch elements are disengaged to allow free rotation of the spool. The disengagement is effected by depressing a radially directed plunger arm 74 such that it slides along a cam surface 75 against the action of a spring leg 82. The depression causes compound movement of the arm 74 and thereby its fork end legs 71, 72 which engage the pinion and move it axially away from the spool until its end 98 is engaged by a latch spring 96. Upon rewinding the rotation of the pinion causes its cammed surface (not shown) to free it from the latch spring whereby the clutch elements are re-engaged by the return of the pinion under the action of the plunger arm 74 and spring leg 82. The reel also includes a friction loaded drive shaft and an anti-reverse ratchet, Figs. 2, 3 (not shown).

Title: Method of and apparatus for twisting or spinning and ballooning yarn from a supply package
IPC: D01H13/10
Filed: 1966-07-25
Abstract: 1,108,456. Twisting apparatus; yarn-brakes; stop motions. PALITEX PROJECT - CO. G.m.b.H. 25 July, 1966 [6 Aug., 1965], No. 33392/66. Heading D1D. In apparatus for spinning (especially in multiple twisting-apparatus), where the material being spun is drawn from a supply package and forms a balloon around the package, means for controlling or acting on the material located within the balloon are operated from outside the balloon by a voltage transmitted across the balloon. The material being spun may be yarn roving, slubbing, or other filamentary or stranded material. The voltage is transmitted by one element of a transformer outside the balloon to another element inside it, which is connected, if necessary through a rectifier, to the controlling means; the latter may be a yarn-brake, a yarn-severing device, a flyer, or drafting or feed rollers. In Fig. 1, the primary element 14 of the transformer is mounted at the base of a balloon-restrictor 10 of two-for-one twisting-apparatus, the secondary element 16 being mounted at a corresponding position on the stationary package holder. The secondary is connected through a rectifier with a coil 22 which controls a cartridge-brake 20 cooperating with upper and lower seatings 18, 19. As shown, the lower seating is of magnetic material and is urged by a spring 23, the force exerted by which is modified when the coil is excited. In another form, Fig. 2, not shown, the lower seating is provided with a magnetic ring which is repelled according to the strength of excitation of the coil. In Fig. 3, the transformer elements are disposed half way up the restrictor and holder; the secondary is connected to a coil 26 acting on a magnetic shoe 27 cooperating to brake the yarn with a surface 29 in the yarn-inlet. In another form, Fig. 4, not shown, a cartridge-brake again cooperates with upper and lower seatings, the upper seating being pressed downwardly by a spring and the lower one bearing against a cam-disc rotated by a step-by-step motor &c. worked by impulses from the secondary. The secondary may also excite a coil 30 (Fig. 3) to attract a spring-urged magnetic severing- element 31 into the path of the yarn, e.g. when the yarn breaks, or when the receiving package attains a desired diameter. In Fig. 5, a flyer 32 to assist unwinding of the yarn, is carried by a hub 35 rotatably mounted on the input tube 9. The hub has a magnetic surface 36 which can be attracted when a coil 37 is energized to brake the flyer or repelled, when the polarity of the coil is reversed, to "suspend" the flyer and cause it to rotate freely. In Fig. 7, drafting rollers 40, 40' are arranged in the input tube and are driven by motors 38 through gears 39, the motors being supplied from the secondary through a rectifier 240. Rollers to assist feeding of the yarn may be similarly driven, Fig. 6 not shown. The primary voltage in a number of spindles may be controlled from a central point.

Abstract: 1,114,318. Timing ignition. SOC. ANON. ANDRE CITROEN. Aug.4, 1965 [Aug. 7, 1964], No.33432/65. Heading F1B. Ignition is further advanced when the engine is idling with the throttle-valve 2 fully closed over the initial setting of ignition timing provided by the conventional vacuum ignition timing control means. During idling the slide-valve 6 is displaced upwardly and brings the pipe 4 into communication with the pipe 7 leading to the ignition distributer. This advances the ignition. When the throttle is opened the slide-valve 6 falls and brings the pipe 3 into communication with the pipe 7. The ignition advance is then controlled in an orthodox manner. In a modification the slide valve is replaced by two non-return valves.
