Title: Process and apparatus for carrying out chemical reactions at high temperatures
IPC: C10G9/00
Filed: 1956-05-14
Abstract: <PICT:0834419/IV (b)/1> Unsaturated hydrocarbons, particularly acetylene and ethylene are produced by the pyrolysis of more saturated hydrocarbons by contact with a hot combustion product gas, the combustion product being continuously produced by the introduction of a fuel and an oxidizing gas separately into a combustion chamber of substantially circular cross-section, at least one of the reactants being introduced by at least one inlet tangential to the periphery with a velocity of at least 0.8 Mach number. Preferably both fuel and oxidizing gas are introduced tangentially and the hydrocarbon to be pyrolyzed is also introduced into the combustion product tangentially, and if desired any one of the reactants may be introduced wholly or partially in a direction of rotation opposed to the other reactants.  The combustion products are preferably cooled slightly by the introduction of a secondary gas such as steam so that oxygen containing radicals are eliminated, as described in Specification 823,956, and the combustion product may pass through a constricted opening before introducing the hydrocarbon.  Suitable fuels are hydrocarbons, commercial hydrogen, carbon monoxide or water gas, and commercial oxygen may be used as the oxidizing gas.  Referring to the drawings, a combustion chamber 1 is supplied with tangential inlets 2 for hydrogen and tangential inlets 3 for oxygen.  As seen from section A these are preferably arranged alternately round the chamber.  They may be in one or more planes.  Steam is introduced radially or tangentially through inlets 4 and the hydrocarbon to be pyrolized through inlets 5 preferably tangentially as in section B.  The reactants pass through the reactor 6 lined with ceramic material 9 and are quenched by a cooling agent introduced at 7.  Gases are separated from any liquids in the syphon 8. Hydrocarbons which can be pyrolized include methane, ethane, propane, butane, pentane, heptane, octane, decane, dodecane and gasoline fractions; isobutane, isooctane, isoheptane and isohexane; ethylene, propylene and n- and iso-butylenes.
Patent GB-464542-A (GB)
Title: Stiffening lining and method of preparing same
IPC: D06M17/06
Filed: 1936-05-27
Abstract: A stiffening lining for use in collars, cuffs, shirt-fronts and the like is obtained by treating fabric or paper with vinyl resins which will soften and lose their adhesive properties below 100 DEG  C. when washed, and recover them when hot ironed, together with at least 5 per cent of a filler such as zinc oxide.  This ensures that the stiffening lining is cleaned during washing.  The resin preferably softens at 60--80 DEG  C., and different vinyl resins may be mixed to attain this temperature.  In an example, a cotton fabric is impregnated with a solution of vinyl resin sold under the trade name "Resonyl N.M." in benzol, with zinc oxide.

Stripped pieces of the developed film are assembled between two translucent sheets of paper to complete a page of matter in a form convenient for storage.
Patent GB-1107323-A (GB)
Title: Photographic camera
IPC: G03B7/085
Filed: 1965-04-09
Abstract: 1,107,323. Exposure control apparatus. EASTMAN KODAK CO. April 9, 1965 [April 11, 1964], No. 15125/65. Heading G2A. An automatic exposure control has a photoresistance 2a forming part of a bridge circuit also including resistors 2c, 2d, a variable resistor 2b, a cell 9 and an electromagnet 10. The quantity of light striking the photo-resistance 2a is dependent on scene brightness, on preset exposure factors, and on at least another exposure factor which during camera release constantly changes from one limit value. When a predetermined voltage exists across the bridge, the constantly changing exposure factor is prevented from further change during shutter release. A diaphragm 3 comprising blades 12 and 13, set in accordance with shutter speed and film speed respectively, masks the photo-resistance 2a. A shutter release 16 is depressible against the action of a spring (not shown), such that a cam surface 17 closes a switch 8 and then a cam 18 retracts bar 19 to disengage nose 22 from a recess 23. The downward movement of release 16 rotates gears 28, 29 thus adjusting lens diaphragm 7 and mask 14. The resistance of photoresistance 2a decreases with increase of the amount of light falling thereon, such that the bridge becomes balanced when no current flows through the winding of electromagnet 10. Armature 11 is released and is moved by spring 27 to disengage gear 29 from the rack carrying mask 14 to prevent further adjustment of the mask 14 and lens diaphragm. A reset mechanism, e. g., a film winding and shutter cocking mechanism returns lever 25 against spring 27 until the armature is again attracted. In a modification (not shown) lens diaphragm 7 and mask 14 are adjusted by an electric motor (not shown) which also effects film feeding and shutter cocking.

Patent GB-368154-A (GB)
Title: Improvements in and relating to austenitic ferrous alloys and articles made thereof
IPC: C21D8/00
Filed: 1931-05-26
Abstract: In order to enable corrosion-resistant austenitic chromium-iron alloys to retain their physical properties at elevated temperatures, an alloy having a low carbon content is given a small grain structure by hot or cold working and is then cooled from a temperature such that the alloy will be ductile and the grain structure small.  The temperature may be above but near the re-crystallization temperature. In hot working, the finishing temperature of any operation which involves substantial deformation should be above the temperature at which ductility is substantially reduced whilst low enough to obtain the desired small grain structure.  For plain chromium-nickel-iron-carbon alloys the working temperature should be down to about 980 DEG  C., or somewhat lower if the alloy contains additions such as silicon or molybdenum, and should not be higher than about 1010 DEG  C.  In cold working, the alloy may be softened by re-heating, the temperature and duration of heating being arranged so as not to induce a growth of the grain structure.  Cooling may be effected quickly or slowly.  The class of alloy to which the invention particularly relates contains 10-22 per cent of chromium, 7-15 per cent of nickel, a low carbon content of not more than 0,07-0,15 per cent, and sometimes small quantities of additional elements such as molybdenum, silicon, vanadium, tungsten, and titanium.  In some cases the carbon content may be up to 0,2 per cent, e.g. when the alloy contains silicon, in order to preserve the austenitic properties of the material.  Alloys produced according to the invention are stated substantially to preserve their physical and corrosive-resisting properties throughout a temperature range of about 480 DEG  C. to about 730 DEG  C.
