Abstract: 1,190,497. Packaging. MASCHINENFABRIK FR. NIEPMANN & CO. 24 Oct., 1968, No. 50533/68. Heading B8C. A textile tear-off thread 4 is attached to a thin sheet of plastics, cellulose, paper or similar material 3, by drawing it through a bath 5 filled with a thermoplastic hot-setting adhesive, pressing the adhesive on to the thread, and then rolling the thread on to the sheet. The thread is guided in the bath by eyelets 11, 12 and passes out through a converging nozzle 13 which presses the adhesive on to the thread as it leaves the bath. The thread is pressed on to the material 3 by rollers 1, 2 which are wetted by wick 15 to prevent sticking. There may be a guide roller 17. The guiding eyelets 11, 12 are carried on lid 9 and the bath is electrically heated.
Patent GB-1120022-A (GB)
Title: Dealkylation process
Inventor: SWANSON WILLIAM MASON
IPC: C10G65/12
Filed: 1965-11-29
Abstract: A process for dealkylating an alkylaromatic hydrocarbon charge stock containing monoand di-olefins comprises the following stages: (1) hydrogenating the charge stock at 150-290 DEG  C. under conditions such that at least part of the olefins are hydrogenated, the aromatic hydrocarbons being substantially unaffected; and (2) treating at least part of the effluent from the first stage with hydrogen at 540-815 DEG  C. under dealkylation conditions.  When the original charge stock contains other contaminants, e.g. sulphur compounds, a third stage may follow the others, the effluent from the second stage being treated with hydrogen under desulphurization conditions, the temperature being at least 290 DEG  C.  Catalysts for each stage are specified, the preferred ones being a composite of molybdenum and an iron-group metal on alumina for the first and third stages, and one of chromium, cesium, vanadium and tungsten on alumina for the second stage. Preferably each stage operates at a pressure of 20-68 atmospheres gauge.  In the example, the charge stock is a coke oven by-product wash oil containing about 15 wt. per cent naphthalene, 35% methyl naphthalene, and 32% other alkylaromatic hydrocarbons, the remainder being olefins, di-olefins, sulphur compounds and nitrogenous compounds.  The recovery of product, based on the original charge, is 10% benzene and 60% naphthalene.

Abstract: 1,023,510. Controlling reactors. UNITED KINGDOM ATOMIC ENERGY AUTHORITY. Dee. 23, 1964 [Dec. 30, 1963], No. 51141/63. Heading G6C. A reactor control arrangement comprises a pair of coupled control members movable in adjacent parallel paths in the core; the first member comprises a nuclear fuel portion in the core and a neutron absorbing portion half the length of the fuel and extending coaxially from one end of the fuel so as to project beyond the core; the second member of the pair is identical to the first, but its absorbing portion projects from the opposite side of the core to the absorbing portion of the first member; provision is made for moving the two members in opposite directions to introduce the absorbing portions into the core. The arrangement is intended for use in a liquid cooled and moderated reactor, and the absorbing members are preferably tubular, so that they contain moderator. The fuel comprises assembled clusters of fuel rods, some of which are fixed in the core, and some of which are coupled to form control arrangements. In a first embodiment, Fig. 1, the pairs of control members 5 are coupled by chains 8. Actuation is by means of hydraulic pressure applied within one of the absorbing tubes, acting against a spring which returns the pair to a shutdown position in the absence of hydraulic pressure. Liquid damping is included to prevent shock loading at the end of control member movement. In a second embodiment, the chain linkage is replaced by a hydraulic connection between the two members forming each pair, and in a third embodiment, the opposite movement of the members of each pair is effected by each member having a co-extensive rack meshing each on opposite sides of a pinion.

Abstract: 1,065,698. Tubular heat exchangers. G. L. BEUSEN. Dec. 30, 1963, No. 51178/63. Heading F4S. Two spaced concentric tanks formed by an outer double-walled cylinder 1 and an inner drum 6 are interconnected by a bank of heat exchange tubes 7, each having a flat spiral shape adapted to meet the walls of each tank at an acute angle and defining a first fluid flow path from the drum to the cylinder annulus through said tubes, and a fan 3 or other flow producing means, such as a pump, passing a second fluid across said tubes, the fan or other flow producing means being coaxially arranged with the tanks, preferably in a single wall extension 2, and having a hub 5 or other flow guiding means of equivalent diameter to that of the drum to enable the drum to be disposed in the disturbed flow region of the hub. As shown, the inner drum is sub-divided by a transverse wall 8 to permit the first fluid to make two passes through upper and lower tube bank sections, the tubes of each respective section having opposite curvature as illustrated in Fig. 2 (not shown). The drum and/or outer cylinder may incorporate more than one transverse wall to provide more than two fluid passes.

Filed: 1971-11-04
Abstract: 1352629 Filtration apparatus H J TITUS 4 Nov 1971 [9 Nov 1970] 51243/71 Heading BID Liquid is separated from a suspension of solid particles in liquid by forcing the suspension under pressure through passage 22 into an apparatus comprising two hollow filter elements 26, 27 which are mounted on flanges 23, 24, 30, 31 and are rotated in opposite senses by belt pulleys 42, 39 attached to co-axial shafts 32, 33 respectively. Filter elements 26 and 27 are both provided with radial bores; and a support-gauze and filter cloth are secured to the outer wall of element 27 and to the inner wall of element 26. As the suspension flows through the annular chamber 25 between the oppositely-rotating filter elements, liquid passes outwardly through the bores of element 26 and cascades down over radial plates (not shown) to container 13; and liquid also passes inwardly through the bores of element 27, and flows down hollow shaft 18 to container 13. Thickened suspension is discharged from the apparatus through passage 37, an adjustable slide valve 38 enabling a high pressure to be maintained within the apparatus; and this thickened suspension may, if desired, be recirculated to inlet passage 22. Belt pulleys are each associated with a drive which can be independently regulated. Filter cake deposited on the filter cloths of the elements is washed by supplying washing liquid to the inner filter element through pipe 47. The interior of the inner filter element may be divided by partitions into filtration zones and washing zones (Fig. 2, not shown), and the partitions may be adjustable. The cylindrical filter elements may be replaced by other hollow bodies of revolution, e.g. frusto-conical filter elements. The apparatus may be used for the separation of liquid from coloidal suspensions of microcapillaries or organically formed tubes.

Abstract: 1520350 Automatic control of position INTERNATIONAL BUSINESS MACHINES CORP 22 Dec 1976 53582/76 Addition to 1503972 Headings G3N and G3R The multi disc stack system of British Patent No 1503972 is modified to compensate for the non linearity of the position information signals used to control the servo during track following. If the servo head becomes offset from its on track position by more than  of a track width during track following (i.e. position p2 on Fig. 2) a non linear region is entered. The quadrature position error signal Q (distinct from the normal waveform N) is used to effectively extend the linear region beyond the  track range thereby maintaining the A.C. gain of the servo circuits constant over the entire displacement range which may occur during track following. This is effected by applying a D.C. off-set to the quadrature signal to give waveform Q'.
