Title: Improvements in or relating to the surface modification of highly disposed oxides
IPC: C09C1/30
Filed: 1963-03-15
Abstract: <FORM:1031764/C1/1> Highly dispersed oxides, oxide mixtures or mixed oxides of metals and/or silicon obtained from volatile compounds of these metals or silicon by known methods are surface modified by reacting the freshly prepared finely divided oxides under exclusion of oxygen and in the presence of 0.5-2 mols. steam per 100 m.3 surface with any substance A capable of reacting with the free or liberated surface hydroxyl groups.  A, preferably 1.5 m.mol./g. oxide, may be an alcohol, aldehyde, ketone, alkali but preferably an alkyl- or aryl- or alkyl-aryl-halogensilane or -alkoxysilane, numerous examples being listed.  Essential deacidification of the oxide to less than 0.5% by weight of hydrogen halide, dehydration to less than 0.9% water and dehalogenation is carried out prior to or advantageously simultaneously with the surface modification reaction. An inert gas, e.g. neon, argon, xenon, a hydrocarbon or tube 28 containing the fibres at a temperature of about 1360 DEG  F. whilst a positive external pressure is applied in chamber 105 to the tube 28 and a vacuum is created within tube 28.  To prevent any distortion, and, if required, to provide an attenuating force, as the tube 28 collapses inward and the fibres fuse together an upward force is applied to the top of tube 28 by attaching a weight 146 or a motor via a wire to a button on the closed end of tube 28.  The combination is then annealed and cooled.  The whole of the furnace is water-cooled by a tube 118 running around the outside.  Fibres having a core of lanthanum flint glass and a cladding of a borosilicate glass, or a core of arsenic trisulphide glass and a cladding of arsenic sulphide glass, or a core of 1.75 m  flint glass cladded with 1.52 m  crown or soda lime glass may be used. The fibres may also be in tubular form without core parts or they may have central openings extending longitudinally through said core parts.  Also the core may be formed from a suitable electrical conducting metallic material such as steel or an amalgam.  Devices made according to the invention may be used in the face plates of cathode-ray tubes.  Reference has been directed by the Comptroller to Specification 925,335.

Filed: 1971-04-21
Abstract: 1331327 Measuring dielectric constant; Electro-physical measurement CHEVRON RESEARCH CO 21 April 1971 [26 June 1970] 10606/71 Headings G1N and G1U The real part #' of the complex dielectric constant # of a liquid medium containing one or more polar constituents (e.g. water) and/or conducting impurities (e.g. clay) is determined by measuring the capacitance C of a capacitance probe inserted into the medium using a measuring circuit operating at 10-300 MHz, and calculating #' from the equation e' = C/Co, where Co is the capacitance of the probe in vacuo. The method is applicable to determining the percentage of water in a water/oil emulsion containing clay particles, the imaginary part #" of #, arising from conduction by the clay and from water dipole absorption, being negligible in the frequency range 10-300 MHz. The capacitance measuring circuit may be a conventional balanced bridge Fig.2 (not shown), or may utilize resonant circuits or transmission line techniques.

Title: Catalyst components for olefine polymerisation
Inventor: CAUNT ANTHONY DAVID
IPC: C08F10/00
Filed: 1962-03-20
Abstract: TiCl4 is reduced (in the presence of red #c,g  TiCl3 and in an inert solvent) at a temperature of from -20 DEG  C. to +20 DEG  C. by an organo metallic reducing reagent which if used to reduce TiCl4 in the absence of red #c,g  TiCl3 would give rise to TiCl3 wholly or partly in the b  form. The red TiCl3 may be prepared by reduction of TiCl4 with C2H5AlCl2 at 0 DEG  C., and is preferably used in an amount less than 10% molar of the TiCl4 to be reduced. The organo-metallic reducing reagent may be an aluminium trialkyl in which each alkyl contains less than 5 carbon atoms, or an aluminium dialkyl halide such as aluminium diethyl chloride.  In the example, TiCl4 is added to a stirred petrol solution of C2H5AlCl2 at 0 DEG  C. (C2H5)2AlCl and more TiCl4 are added to the solution.  The product is filtered off, washed with petrol at 0 DEG  C. and subjected to heat treatment at 85% in a stirred 0.3 m. petrol slurry.ALSO:a -olefines are polymerized in the presence of a catalyst which is the product of the reduction of TiCl4 in an inert solvent at - 20 DEG  to +20 DEG  in the presence of red a ,g TiCl3 by an organometallic reducing agent which if used to reduce TiCl4 in the absence of red a ,g TiCl3 would give rise to TiCl3 in the b -form.  The organometallic reducing reagents may be an aluminium trialkyl in which each alkyl contains less than 5 carbon atoms or an aluminium dialkyl halide. In an example propylene is polymerized at 50 DEG  C. in a high-boiling petrol containing 10 millimetres/litre Ti activated by (C2H5)2AlCl The resulting polymer has lower per cent soluble in heptane than polymer prepared using prior art catalyst of this type.ALSO:A component of a catalyst for polymerizing a -olefines is produced by reducing TiCl4 in an inert solvent in the presence of red a ,g  TiCl3 at a temperature of from -20  DEG C. to +20  DEG C. with an organo-metallic reducing agent which if used to reduce TiCl4 in the absence of red a ,g  TiCl3 would give rise to TiCl3 wholly or partly in the b -form.  The red TiCl3 may be prepared by reduction of TiCl4 with C2W5AlCl2 at 0  DEG C., and is preferably used in an amount less than 10% molar of the TiCl4 to be reduced.  The organo-metallic reducing agent may be an aluminium trialkyl in which each alkyl contains less than 5 carbon atoms, or an aluminium dialkyl halide such as aluminium diethyl chloride.

IPC: B65H67/06
Filed: 1958-04-03
Abstract: 902,325. Packaging machines. MUSCHAMP TEXTILE MACHINERY Ltd. Sept. 25, 1958 [April 3, 1958], No. 10717/58. Class 94(1). [Also in Group IX] In apparatus for collecting and stacking packages such as pirns or bobbins released by an automatic winding machine (see Group IX) packages are received in an inclined position and presented in horizontal position to, and assembled as a single layer on, layer collector supports whence the complete layer is transferred to a member which is lowered into a container e.g. a weft box, as each layer is released by the collector, the last received layer being held just below the layer collector. If pirns are required in columns, the box may be partitioned to form compartments into which pirns fall selectively as they are released bodily as a layer, or separate column holding boxes may be used. In the operation of the apparatus shown, each pirn is dropped on to a flap 14 which tilts and slides the pirn into a receiving member 18 wherein it rests against an abutment 18a. A lever 24 actuated from the machine pulls on a link 30 and, through bell crank 29, spring 28a, rod 28 and bell crank 26, lowers member 18 to horizontal position: roller 46 engages cam lever 45 and, through a spring 44 and arms 43, moves a push plate 41 to shift the pirn on to end flaps 33 where on a layer accumulates until an end pirn, Fig. 3, is about to engage a pusher bar 39. When the next pern is delivered, the preceding pirn is pushed against bar 39 to release catches 36 holding flaps 33 so that the pirns fall simultaneously as a layer on to layer receiving rods 49 positioned just below the edge of a box 47 and the flaps 33 are returned by springs 35 to their layer supporting position. The weight of pirns on rods 49 depresses them, against the adjustable loading of a spring 59, into the box a distance approximately the depth of the layer. The operation proceeds with successively superposed layers descending until the box is full whereupon it is moved along its platform so that rods 49 are withdrawn (from under the lowermost pirns) through slots 48 in the box and return to their initial position in preparation for filling of the next box.
