The sheet or foil is sufficiently thin to enable it to be inserted in a typewriter, and the design is applied thereto by means of a composition with which the ink-ribbon is impregnated, the prepared sheet being employed without the necessity for treating with a gum solution. The anodized aluminium is subjected to a treatment with water or an aqueous solution of cobalt acetate, nickel acetate, and, if desired, boric acid, heated to a temperature of 200-212‹ F. ; if the solution of salts is employed, the sheet is preferably treated subsequently in boiling water. The anodized surfaces may be dyed in order to destroy or modify the glossy appearance and reflective properties. The sheet may be backed with paper or other flexible material, and may be provided with means for securing it in place in a duplicating-machine.

Patent GB-861991-A (GB)
Title: Improvements relating to methods for the production of titanium tetrachloride
Inventor: EVANS ARTHUR WALLACE
IPC: C22B34/12
Filed: 1956-06-28
Abstract: Titanium-bearing material is subjected to fluidized-bed chlorination in admixture with carbon, coke or anthracite by means of an upflowing stream of chlorine or a gas mixture containing it.  The fluidized bed is supported on a plate having perforations fitted with insert members defining orifices of reduced diameter. Titanium tetrachloride together with ferric chloride and other contaminating chlorides are simultaneously formed and removed together as a single gaseous mixture whilst the less readily chlorinated constituents accumulate in the bed from which they are periodically or continuously removed. The ore feed is preferably of 80-180 micron size whilst that of the carbon or coke is approximately twice this size.  The gases enter the furnace at 2-50 times the minimum fluidizing velocity and the reaction temperature is maintained within the range of 500-1000 DEG C. According to an example the bed was formed of 1 part powdered coke and 4 parts of rutile sand which contained 1.2% of zircon.  The bed was initially fluidized by admitting air and heating with a gas flame to 900 DEG  C., after which air was cut off and chlorine fed at 15 DEG  C.  The bed was supported upon a perforated plate, the pressure drop across which was 3 1/2 lbs./square inch, and slightly less than the pressure drop across the bed.  Titanium tetrachloride was fed through the top of the reaction vessel in a solid stream which fell into and, by evaporation, cooled the bed and maintained the temperature at 870 DEG  C.  The zircon content of the bed built up to 40% after which air flow replaced chlorine and a portion of the bed was removed through a port in the side of the reactor.  Fresh rutile and coke was then added and chlorination continued.

IPC: C07C4/10
Filed: 1961-06-05
Abstract: <PICT:0938823/III/1> Acetylene is obtained from a C1-C3 hydrocarbon feed by passing through a rotating electric arc, thereby heating the feed to above 1600 DEG C., cooling to not less than 1100 DEG C. within 0,1 second by adding a second hydrocarbon at a temperature below 1100 DEG C. and having a molecular weight at least that of the feed but not more than 150 and quickly quenching the effluent to below 300 DEG C.  The feed is preferably methane or propane and the cooling hydrocarbon, which is also pyrolysed, may be methane, propane, butane, toluene, divinylacetylene or gasoline.  The final quench is effected with water, preferably within 0,1 second of the arc.  In the apparatus shown in the drawing the reaction is effected in the copper cylinder 10 which also forms the anode, the cathode being a central graphite electrode 15.  The arc is rotated by a D.C. current passing through the coaxial field coil 31.  The feed enters at 11 and passes through distributer 12, the cooling hydrocarbon is introduced through inlets 35 and the water coolant through spray 37.

Abstract: 653,869. Hydraulic shock absorbers. GIRLING, Ltd. July 29, 1948, No. 20199. [Class 108(iii)] In an hydraulic shock absorber for vehicles, of the kind in which a restricted liquid-flow passage is formed by the clearance between the peripheral surface of the piston A and cylinder wall a, the clearance is provided by an intermediate portion c of the piston of relatively short axial length having an annular groove on each side of it connected by one or more longitudinal grooves or passages e of substantial cross-sectional area, to the adjacent end of the piston. The invention is described as applied to the pistons of both direct-acting (Figs, 3, 4, not shown), and double-acting (Figs. 5, 6, not shown), shock absorbers. These pistons have in addition to the working clearance, valve controlled ports. The end portions b of the pistons minimise the effect of tilting of the piston (due to wear) on the clearance c. The piston is made of aluminium or a zinc base alloy, and the cylinder of cast iron, so that the liquid flow clearance is reduced with a rise in temperature.
