Title: Processes for preparing motor fuels and liquid hydrocarbon mixtures suitable as motor fuel components
IPC: C10L1/06
Filed: 1955-10-27
Abstract: A mixture of liquid hydrocarbons of improved octane number suitable for use as a motor fuel component is obtained by catalytically reforming a paraffinic or naphthenic straight-run gasoline or gasoline fraction and removing from the resulting reformate by fractional distillation a fraction having an initial boiling point of between 80 DEG  and 85 DEG  C. and a final boiling point of about 105 DEG  C.  In addition, the fraction boiling from 105 DEG  to 135 DEG C. may also be removed.  In an example a straight-run naphtha with a boiling range of 93-191 DEG  C. containing 59.5 per cent by weight of paraffinic hydrocarbons was passed over a catalyst at a rate of 2.3 litres per litre of catalyst per hour together with hydrogen-rich recycle gas in a quantity corresponding to 8 mols. of hydrogen per mol. of naphtha at a temperature of 460-500 DEG  C. and a pressure of 40 atmospheres.  After separating the hydrogen-rich gas phase the product was stabilized and then the fraction boiling between 82 DEG and 132 DEG  C. was removed.  The catalyst may be platinum, molybdenum oxide or chromium oxide supported on an alumina carrier, with or without chlorine or fluorine.

Title: Treatment for films of vanadium iv-hardened polyvinyl alcohol
IPC: C08J7/00
Filed: 1970-06-25
Abstract: 1,253,954. Treating polyvinylalcohol-vanadium IV films. NATIONAL CASH REGISTER CO. 25 June, 1970 [14 July, 1969], No. 30902/70. Heading B5B. [Also in Divisions B8 and C3] The water-solubility of films at least partly composed of a polyvinyl alcohol-vanadium IV complex which is not readily water-soluble is increased by oxidizing the vanadium IV without degrading the polyvinyl alcohol. The oxidizing agent may be in an aqueous solution or in the form of a gas or vapour. The gaseous or vaporous oxidizing agents may be ammonia and/or a volatile amine with or without hydrogen peroxide. Various agents may be used in aqueous solution; particularly mentioned are hydrogen peroxide; sodium hypochlorite; an N-halogenated amine, amide or imide, or a water-soluble salt of one of those last. Also useful oxidizing agents are perborates, but in this case a polyhydroxy compound, such as mannitol, sorbitol, glycerol, pentaerythritol, 1,1,1-tris-(hydroxymethyl) ethane or mannose, should be added to complex the borate ions produced during the oxidation process. The process is particularly useful when the film material is forming a capsule containing liquid or solid particles, in which case the oxidizing agent should be chosen such that it does not attack these particles. The term " polyvinyl alcohol " as used herein also includes material containing vinyl alcohol together with vinyl acetate and/or propionate and/or butyrate, wherein the vinyl alcohol constitutes at least 50% by weight; such polymeric material should preferably be readily water-soluble. The films used in this invention frequently contain hydroxyl compounds complexed with the polyvinyl alcohol and the vanadium. When the hydroxyl compound is a borate or an alkylene cyclic borate ester, then a boratesequestering agent, as mentioned above, should be used to remove the borate ions.

Title: Method of forming apertures in a hollow member and apparatus  therefor
IPC: B21D22/28
Filed: 1972-07-04
Abstract: 1435079 Punching D BROWN 3 July 1973 [4 July 1972] 31133/72 Heading B3W To punch a hole in a hollow elongate member, a die support member, supporting a die located transversely of the support member and itself located transversely within the hollow member, is moved between the die and a portion of the hollow member remote from an external punch to move the die into engagement with the internal surface of the hollow member in alignment with the punch and the punch is operated. As shown, Fig. 1, a punch 22 co-operates with a die 12 mounted on a holder 14 which is fixed at 16 to the machine bed 18 and is disposed in a groove 34 in a support 32, the die resting on an inclined face 30 of the support 32. The support is movable longitudinally of a tube 10 to be perforated, to the right by means of a manuallyactuated bell-crank 52, and levers 46, 38 and 36 and to the left by means of a spring 56, which moves the die out of and into engagement respectively with the tube. The die, the tube and the support are located transversely by means of spring-loaded balls (60), (66) (Fig. 2, not shown) acting between the support and the tube and between the tube and side walls (64) of the machine. The slug punched out falls through apertures 24 and 70 and passes through an opening 72 when the support is moved to the right to lower the die. Pivoting the bell-crank to move the support to the right also indexes the tube along the machine bed as follows. Slidable on a rod 78 between two adjustably spaced collars 80 is a block 76 which engages a pin 74 slidable in a slot in the lever 38. The other end of the rod 78 is pivoted to a rod 82 which is slidably mounted on the bed 18 and urged towards the lever 38 by a spring 84. Pivoted to a lug 86 on the rod 82 is an inverted U-section latch assembly 88 urged by a spring 90 on to the top of the tube, a spigot 98 on the latch assembly 88 being held in an already punched hole 68 by a spring loaded safety catch 96. Before the bell-crank is pivoted anticlockwise the safety catch 96 is released manually to release the spigot and allow the rod 82 to move to the right under the action of spring 84 until the left hand collar 80 abuts the block 76. The spigot 98 is then engaged in the next punched hole 50 that on pivoting the bellcrank 52 anticlockwise the rods 78, 82, the latch assembly 88 and the tube 10 move to the left until an axially adjustable nut 94 on the rod 82 abuts a stop 92 on the machine bed. The catch 96 prevents the latch assembly 88 returning under the action of spring 84 when the bell-crank lever is released and allowed to pivot clockwise to raise the die ready for the next punch stroke. The punch has a fixed stripper 62. In alternative embodiments not described in detail, the die is raised and lowered by fluidoperated, screw or cam mechanism. Similarly the tube indexing means may be replaced by electric, fluid or screw mechanism.

[Also in Division G2] A galvanometer movement includes a mirror 6 mounted on a suspension filament 4 and having a thickness and reflective surface area to mass ratio substantially less than would be practicable if it were made of glass by virtue of being made entirely or primarily of a material which, at that thickness, is stiff and resistant to deformation at high frequencies of oscillation. The material may be silicon, germanium, quartz, mica or synthetic mica. With a thickness of not more than 0À001 inches, the mirror may have a width of at least 0À025 inches in a direction transverse to its axis of rotation and a flatness better than 10 micro-inches in the same direction. The reflective surface may be a surface of the material or it may be a layer of vacuum deposited aluminium which may be protected by a layer of vacuum deposited silicon monoxide. The mirror 6 may be bonded to the filament 4 with a dot of epoxy resin and to counteract any stress set up during hardening another dot of resin is applied to the front surface of the mirror in a corresponding position. A method of constructing the movement is described including the steps of lapping and polishing a surface of a silicon chip, masking the surface while etching the chip to required thickness and reducing to size by scribing and breaking or etching to size.
