Title: Improvements in or relating to the low pressure catalytic polymerisation of olefinic
Inventor: WHITEHEAD THOMAS WILFRED
IPC: C08F10/00
Filed: 1958-09-24
Abstract: Polymers of olefinically unsaturated hydrocarbons are made by polymerizing the compound in the presence of a catalyst consisting of a component (A) and component (B) as later explained, in a plurality of stages in which the polymerization in the first stage is effected using a high concentration of the catalyst, i.e. a concentration of more than 20 millimols per litre of (A), and at least one subsequent stage in which the reaction medium withdrawn from the first stage is fed with additional hydrocarbon and further polymerization is effected using a conventional catalyst concentration, i.e. less than 20 millimols per litre of (A).  The (A) component of the catalyst is a transition metal compound wherein the metal is in a lower than normal valency state and is preferably a compound of Group IVa, Va, VIa, VIIa or VIII of the Periodic Table, and the (B) component a metal, hydride, or organo-metallic compound of Group I, II, or III, or tin, or lead, or an organic boron compound or addition complex thereof.  The polymerization is preferably effected in the liquid phase, but the first stage may be carried out in the gaseous phase and subsequent stages in the liquid phase or the entire polymerization may be effected in the gaseous phase.  The gaseous phase polymerization is effected by vaporizing the catalyst components.  When the first stage polymerization is effected in the liquid phase, a relatively viscous liquid medium is preferred, e.g. by adding a thickener or stabilizer such as polyisobutylene, to the solvent which may be isooctane.  The olefinic monomer may be ethylene, propylene, n-butylene, or mixtures, or styrene.  The monomer may be admixed with diluents such as ethane.  The exemplified catalyst is titanium tetrachloride ((A) component), and aluminium diethyl monochloride ((B) component).  The process may be operated continuously or batchwise and the ingredients utilized may be added portionwise. Specifications 799,332, 799,823, 801,031, 810,023, 819,867, 820,263, 837,064 and 840,859 are referred to.

Title: Process and apparatus for forming transverse corrugations of all forms in a sheet orband of malleable material
IPC: B31F1/30
Filed: 1962-08-09
Abstract: 991, 035. Finishing fabrics-corrugating. L. V. GEWISS. Aug. 9, 1962 [Aug. 9, 1961], No. 30646/62. Heading D1S. A method of forming transverse corrugations in a sheet of pliable material, pre-formed with longitudinal corrugations, in order to obtain a chevron structure, consists in providing a transverse corrugation forming surface which has the configuration of a chevroned structure, feeding the pre-formed sheet at an angle on to said corrugation forming surface so that the longitudinal corrugations of the sheet are substantially parallel with the corresponding corrugation of one flank and abut the reverse flank of the transverse corrugations in the forming surface, and causing said surface to move relatively to the pre-formed sheet, whereby the sheet is caused to wrap around the reverse flank of the corrugation forming surface to complete the chevron structure. As shown a sheet of pliable material 1 which has been previously folded or corrugated longitudinally is fed, between two grooved and mating rolls 2, 3 having profiles corresponding to the sheet corrugations, and then between an inclined guide plate 4 and a guide roll 5. It is thus fed into contact with a continuously moving endless belt 6 which imparts transverse corrugation to the sheet. Belt 6 passes through a point immediately above the upper inclined end of guide plate 4 and comprises (Fig. 4) three thin flexible bands 6a, 6b and 6c to which are spaced shaped elements 10. These elements may be herringbone in form (as shown), sinuous or straight having triangular or sinuous crosssection. The belt may also be replaced by a reciprocating table. An outlet nozzle 12 having an outlet orifice corresponding substantially to the profile of elements 10, is positioned adjacent the upper end of guide plate 4 and is connected to a supply of hot fluid under pressure for blowing the sheet into the corrugating elements. Opposite nozzle 12 on the inside of belt 6 is positioned a suction hood 13. A hood 14 is also provided inside belt 6 and is connected to an air pressure supply for detaching the corrugated sheet from the belt 6 and depositing it on table 9.

Title: Improvements in electric cable systems
IPC: G01M3/18
Filed: 1934-10-27
Abstract: 446,347. Indicating leaks in gas-filled cables. HENLEY'S TELEGRAPH WORKS CO., Ltd., W. T., 11, Holborn Viaduct, London, and DUNSHEATH, P., Hesket, Church Avenue, Sidcup, Kent. Oct. 27, 1934, Nos. 30879/34 and 12436/35. [Class 99 (ii)] Leakage of gas from a faulty gas-filled cable comprising lengths of cable 5 with intermediate joints 3 is indicated by enclosing each cable length in a pipe or sheath 6 with a small clearance between the two and each joint similarly within a pipe or casing 4, and providing means for detecting any substantial rise in pressure in the several clearance spaces. The invention is shown applied to a threephase system employing single-core cables, of the kind described for example in Specification 400,929, [Group XXXVI], running side by side, separate leakage indicators 10 being provided for each group of three joints and each group of cable lengths which are connected to the clearance spaces of the latter by pipes 9, 11 respectively. Each indicator, Fig. 3, comprises a casing divided by two spring-loaded diaphragms 23 into three parts, to each of which one of the pipes 9 or 11 leads, the arrangement being such that a rise of pressure in one or two of the pipes 9 will cause one or both of the diaphragms to move. The diaphragms are fitted with a rod 31 having a projection 33 normally engaging one end of a catch 40 the other end of which holds a contact member 37 away from a plate 36, movement of the diaphragm in one direction or the other causing the catch to release the contact member to complete an electric circuit which includes an alarm signal 15 at an inspection station where apparatus is provided for locating the indicator at which contact has been made. The projection 33 has a laterally extending finger 45, Fig. 4, co-operating with two indicating collars 46 slidable on a fixed pin 47 so that any displacement of the projection is accompanied by movement of one of the collars ; thus by examining the collars in an indicator on which contact has been made the direction of movement of one or both of the diaphragms can be determined. The indicators may also be used for indicating faults in the pipes 4, 6 by filling the clearance spaces with gas at a pressure slightly above or below atmospheric pressure, e.g., an absolute pressure of 2 atmospheres or ¢ atmosphere respectively.

Title: Process and apparatus for ageing alkali cellulose
IPC: C08B1/10
Filed: 1949-12-02
Abstract: Alkali-cellulose is treated to loosen, blend, and fluff the fibres into the form of crumbs, and these are continuously spread uniformly across the top of a vertical ageing-tower of uniform cross-sectional area throughout its height; the tower is maintained full of alkali- <PICT:0672302/IV (a)/1> <PICT:0672302/IV (a)/2> <PICT:0672302/IV (a)/3> <PICT:0672302/IV (a)/4> cellulose crumbs which are allowed to settle by gravity; at the bottom of the tower the crumbs are continuously engaged and picked so as to be removed uniformly from across the bottom area of the tower and so as to cause all the crumb particles to settle at the same uniform rate.  All of the crumb particles thus remain in the tower for the same length of time while passing from the top to the bottom.  The tower may be provided with a jacket for controlling the temperature of ageing.  Air or inert gas may be passed upwardly through the tower.  As shown in Fig. 1, the tower 10 comprises an inner shell 11 and an outer shell 12 spaced therefrom to form a jacket 26.  A conical discharge hopper 16 terminates in a discharge duct 17 having a ball-valve 18 with rotating vanes 19 adapted to discharge the crumbs at a controlled rate while maintaining a vapour seal.  Air or inert gas may be introduced through annular passage 20 and openings 22. Temperature-control fluid may be introduced through duct 25 to the jacket 26.  A discharge picker assembly 35 extends across the bottom of the tower.  This assembly comprises several shafts 38 (Fig. 2), carrying picker fingers 39.  The shafts have worm wheels 71 meshing with worms on shaft 41.  Preferably, alternate shafts 38 rotate in opposite directions.  The picker fingers 39 may take the form of crossed rods, or semi-circular segmental members 39b (Fig. 4), or discs 39c (Fig. 6).  The discs 39c are provided with pins 45.  From the discharge duct 17 of the ageingtower, the alkali-cellulose may be passed to a shredder and thence to a continuously-acting xanthating drum.

Title: The manufacture of dyed artificial masses from regenerated cellulose
IPC: C08L1/00
Filed: 1935-11-08
Abstract: In a process for the manufacture of dyed artificial masses, particularly films and filaments, of regenerated cellulose, a finely dispersed pigment of a reduced vat dyestuff in a form which is insoluble or difficultly soluble in cold alkali and is fairly stable to oxidation by air, and a dispersing agent are incorporated in the cellulose solution from which the cellulose is then regenerated. Suitable stable reduced vat dyestuff are described in Specifications 334,878, 334,919, 334,920, 338,104, [all in Class 2 (iii)], 350,862, and 359,183.  Suitable dispersing or wetting agents are for instance condensation products of higher fatty alcohols or acids with alkylene oxides or substituted carboxylic or sulphonic acids, naphthalene sulphonic acids or their condensation products with formaldehyde, soaps, sulphonated mineral oil, sulphite cellulose waste liquor or mixtures of these substances.  The wetting agent and dyestuff are preferably mixed intimately before use, e.g. in a ball or colloid mill.  The dyestuff is oxidized during the regeneration, e.g. a spinning process or at most after a short storage.  Oxidizing agents, e.g. bichromates may be added to the spinning bath.  In an example, 200 parts of finely dispersed Indanthene Brilliant Pink R are reduced in the presence of 1500 parts of water and 1200 parts of ammonium hydroxide (25 per cent) with the aid of 200 parts of sodium hydrosulphite at 92 DEG  C.  After filtering and washing the reduced dye is made with water into a 13 per cent paste and mixed with 80 parts of a condensation product of oleyl alcohol and ethylene oxide. 23 Per cent of this solution (based on the weight of cellulose) is added to a cuprammonium cellulose solution which is spun in the ordinary way.  Other examples describe the use of Indanthene Brilliant Green B and Indocarbon CL plaste.  The condensation product of oleic acid chloride with albuminous degradation products of protein material or a sulphonated mineral oil may be employed as the dispersing agent.
