Filed: 1962-05-21
Abstract: A two-stage hydrocracking of hydrocarbon distillates boiling in the range 500-1100 DEG  F. or residua boiling above 1050 DEG  F. is effected in a first stage at a conversion of 10-50% volume of feed to products boiling below the initial boiling point of the feed at 550-900 DEG  F., a LHSV of 0.1-3 and a hydrogen partial pressure of 500-3000 p.s.i.g. over a catalyst comprising a hydrogenating-dehydrogenating component alone or deposited on a support of no more than weak acidity and at least part of the effluent is treated in the second zone at a conversion of at least 20% volume to products boiling below the initial boiling point of feed to that zone at 450-850 DEG  F., a LHSV of 0.2-5 and a hydrogen partial pressure of at least 350 p.s.i.g. with a catalyst comprising a hydrogenating-dehydrogenating component on a strongly acidic active cracking support.  The first zone gives high yields of middle distillate product and the second zone high yields of naphtha and by adjustment of the feed to the second zone and recycles yields of naphtha or of middle distillate can be increased or decreased according to requirements.  The hydrogenating-dehydrogenating catalyst in each zone is a metal, or oxide, sulphide or selenide thereof, of Group VI or VIII, or combinations thereof, particularly sulphides of cobalt and/or nickel with sulphides of molybdenum and/or tungsten. In the first zone the support may be a single refractory oxide (not mixed oxides) e.g. silica, alumina, titania, zirconia, kieselguhr or bauxite or charcoal.  Mixed oxides may be used in the second zone, e.g. silica-alumina, or activated alumina, alumina, alumina-BF3 combinations or various fluorided or selenided supports. The product from the first zone is fractionated to recover a naphtha product boiling below 400 DEG  F. and optionally a middle distillate product.  Material boiling above 320 DEG  F. is at least partially passed to the second zone, e.g. that boiling above 500 DEG  F. and part may also be recycled to the first zone.  Product from the second zone is also fractionated, optionally in the same apparatus, to recover naphtha and middle distillate products and material boiling above the initial boiling point of the feed to the second zone may be recycled through the second zone.  U.S.A. Specification 2,944,006 is referred to.ALSO:A catalyst for use in the first stage of a two-stage hydrocarbon hydrocracking process comprises a metal or an oxide, sulphide or selenide thereof of Group VI or VIII, e.g. Co, Ni, Mo and W, supported on a support of no more than weak acidity, e.g. a single refractory oxide, while in the second stage a similar hydrogenating-dehydrogenating component is used on a strongly acidic active cracking support, e.g. charcoal, TiO2, ZrO2, Kieselguhr, bauxite, activated alumina, alumina-BF3 or fluorided or selenided supports.

Title: Improvements in or relating to the treatment of yarns and filaments by pressure rolls
Inventor: CLAPSON BRIAN EDWARD
IPC: D01D10/04
Filed: 1963-05-17
Abstract: Twisted or untwisted, multifilament, nylon yarn at elevated temperature, as may be due to prior passage (under low tension) over and in contact with a convex heated plate, is drawn through the nip of a pair of loaded pressure rolls in such manner that the forward motion of the yarn imparts the rotary motion to the rolls.  Drawing may be effected by the wind-up apparatus e.g. a coning or ring-spindle mechanism.  A third roll, itself driven by the forward motion of the yarn, may drive the pair through gearing, Figs. 1 and 2 (not shown).  The filaments may be deformed and so that their cross-sectional shape varies randomly along their lengths.  The treated yarn may be woven, as warp and/or weft, or knitted e.g. in the welt of a stocking, into fabric which thereby displays "crackiness" i.e. randomly distributed, short, dark lines. Specifications 913,882 and 936,284 are referred to.

Filed: 1933-07-12
Abstract: 420,843. Door-operating appliances. PETERS & CO., Ltd., G. D., and GOODWIN, R. L., Windsor Works, Slough, Buckinghamshire. July 12, 1933, No. 19768. [Class 65 (i)] A fluid-pressure engine for operating doors and the like comprises two pistons 20, 21 of different diameters working in fixed cylinders 25, 26 and connected by a piston-rod 10, the movement of the piston-rod being transmitted to a rockshaft 11 operatively connected to the gate and means being provided on each piston to restrict the exhaust from its cylinder, after a predetermined travel produced by fluid pressure in the other cylinder, to cushion the movement. In the form shown, the smaller piston 20 is constantly acted on by pressure fluid supplied through passage 27, while the larger cylinder is connected alternately to a pressure fluid supply passage 37 and an exhaust passage 40 by an electromagnetically operated valve 34, the exhaust port being normally closed under the action of a spring. The port opening into each cylinder head is closed during the latter part of the exhaust stroke in the cylinder by a valve disc 48 carried by a spring- pressed rod slidable in the piston-rod 10, the fluid escaping during the remainder of the stroke only through a restricted valve-controlled port, such as that shown at 44 in the smaller cylinder, and the movement being therefore checked. In a modification, the valve members 48 may be replaced by valves carried by the cylinder heads and operated by spring-pressed sliding rods carried by the pistons ; in this case the restricted exhaust ports may be formed in the valves or provided by imperfect fitting of the valves. The piston-rod 10 is shown connected to the rockshaft 11 by a telescopic lever having one part 12 fixed to the shaft 11 and the other part 13 pivoted to the piston-rod. Alternatively, a one-piece lever may be used, slidably engaging the piston-rod or connected thereto by a link.

Abstract: 1,163,028. Arrangements of pulleys; loadhandling apparatus. BRITISH HOVERCRAFT CORP. Ltd. 28 March, 1968 [1 May, 1967], No. 20116/67. Headings B8A, B8B and B8H. A system for moving a load 119 which may be air cushion supported, about a restricted floor area comprises winches 115, 116 which through cables 117, 118 connecting the winches to the load and passing over pulleys or fairleads 124, 125 mounted at the perimeter of the floor area and pulleys or fairleads 126 mounted on an overhead movable carriage 128, control the direction and amount of movement of the load. The load is attached to the ends of cable 117 at points 120, 121 and to the ends of cable 118 at points 122, 123 the cables being wound on their respective winch drums intermediate their ends. When the winch drums 115, 116 are driven in the same direction, the load 119 will move in the direction of arrows C or D depending on the direction of rotation of the drums, and when the drums are driven in opposite directions, the forces exerted on the pulleys 126 cause the carriage 128 to move with the load 119 in the direction of either arrow A or B depending on the drum rotation directions. The pulleys 125 are mounted on jacks 127 which by differential manipulation thereof, cause the load 119 to be swivelled about its vertical axis provided the winch drums are rendered freely rotatable by a clutch 131. Both winches 115, 116 are driven from a common motor 129 through a gear-box 130 associated with a brake 132. In the embodiment of Fig. 8 (not shown), the jacks of the first embodiment are replaced by tensioning pulleys and swivelling of the load is effected by locking one of the winch drums and rotating the other. In the embodiment of Fig. 6 (not shown), a single reversible winch drum is used which engages an endless cable loop. The cable engages the load via a pair of pulleys thereon which are braked to render the winch drive effective on the load. The other direction of drive is effected by releasing the brakes and moving the load and overhead carriage either manually or by use of a separate winch drive shown in Fig. 3 (not shown). Fig. 5 and 7 (not shown), show further embodiments in which a single winch shown associated with a single cable drives the load in one direction when the cable is braked.
