Title: Improvements in or relating to internal combustion engines
IPC: B23K20/227
Filed: 1943-10-08
Abstract: 568,589. Materials. MANSELL, H. C., ALEXANDER, W. O., BRISTOL AEROPLANE CO., Ltd., and IMPERIAL CHEMICAL INDUSTRIES, Ltd. Oct. 8. 1943, No. 16490. [Classes 7 (ii) and 7 (vi)] [Also in Groups II and XXVI] Surfaces of cylinder heads, pistons, valves, &c. which are exposed to the burnt gases are constituted by a layer of .010-.015" thick of iron, steel, nickel or nickel alloy, the layer being bonded by heat or heat and pressure to a base of a copper alloy which is suitable for precipitation hardening heat treatment and which retains its strength at operating engine temperatures. Suitable copper alloys contain .26-2 per cent chromium, preferably .45-.75 per cent with or without .001-.05 per cent silver, .5-.7 per cent chromium and .03 per cent silver being most suitable, or the alloy may contain .3-5 per cent zirconium, preferably 1-3 per cent. Blanks for use in making the parts or components are formed by sandwiching a layer of nickel &c. between a thicker layer of copper alloy and a sheet of de-oxidized copper, inserting the whole in a copper or steel envelope and hot rolling the packet at about 900‹ C. to reduce its thickness to one-third. The packet is then emptied, the layer of deoxidized copper removed and the composite nickel-copper sheet cold rolled to the desired thickness ready for blanks to be cut from it. Alternatively, the bonding may be effected by brazing. In forming, for example, a junkhead for a sleeve valve engine, a circular blankis heated to 1000‹ C., softened by quenching in water and then pressed into a shallow cup 7 having indents which can be machined to receive sparking-plug adapters 5 without exposing the copper base to the burnt gases. Before machining, the cups are heated to 1000‹ C., quenched and finally heated at 450‹ C. for four hours. The cup is brazed on to a steel carrying sleeve 9 and cooling fins 8 similarly secured to the cup or silver-soldered thereto. In expectation of this latter operation, the previous heating at 450‹ C. may be omitted.

Title: Improvements in and relating to the treatment of petroleum cracking residues
IPC: C10B49/14
Filed: 1944-08-31
Abstract: <PICT:0580579/III/1> <PICT:0580579/III/2> <PICT:0580579/III/3> Hydrocarbon distillates, coke and asphaltic material are obtained from residues formed in the cracking of petroleum by soaking lumps of coke or like porous carrier with the residue, heating the same in a gaseous or vaporous atmosphere so as to evaporate the more volatile hydrocarbons and leave a coating of the less volatile hydrocarbons and of coke, and submerging the thus coated lumps in a molten metal or salt at a temperature above the softening point of the hydrocarbons forming the coating so as to cause liquid products from the coating to rise to the surface of the molten material. Preferably both steps of the process are carried out within the temperature range of 400 DEG  to 550 DEG C., and a molten lead bath is used.  The composition and proportion of the various fractions obtainable from a given charge can be varied by varying the temperature of the bath, by the application of increased or reduced pressure, and by varying the period during which the coke lumps are inside or outside the bath.  In Figs. 1 and 2, a perforated drum 1 is rotatably mounted in a bath 2 containing molten lead 3.  The drum is divided into sections by radially disposed perforated plates 5, and is two-thirds filled with coke lumps 6.  The preheated charge is introduced into the drum through a pipe 7 and manifold 8.  The vapours evolved escape through pipe 10 and are condensed, and liquid hydrocarbons, displaced by the metal bath, escape through the overflow pipe 11 the opening of which is slightly above the level of the molten metal.  Fresh coke can be charged from hopper 12, while coke which has sufficiently increased in weight is removed to hopper 15 by means of screw conveyer 14.  In Fig. 3, the charge is fed through pipe 25 on to hot coke lumps 26 floating on a bath of molten lead 27.  A short time is allowed for evaporation of volatile constituents, which are removed through pipe 36, and then perforated disc 32 is depressed until all the coke is submerged in the lead; the liquid hydrocarbons released flow through pipe 33 and lead trap 35 into container 34.  Excess coke is removed into hopper 40 with the aid of plunger 38.  Specification 566,281 is referred to.

Abstract: 250,794. Marks, E. C. R., (Danner, E.). June 30, 1925. Drawing; forming reinforced glass.-A method of forming reinforced sheet glass consists in flowing molten glass downwards in two layers, passing a wire fabric or netting between the layers, and causing the two layers of glass to come into contact with the wire netting to form a single sheet enclosing the wire. The glass flows from a tank 1 into a forehearth 2 the bottom of which is formed with an elongated slot or discharge opening 5. A refractory slab 8 is supported in the slot 5, and the glass flows down its sides in two streams b which unite at the bottom to form a single sheet. The slab is formed with an opening 11 through which a band of wire netting 12, drawn from a roll 13, is passed. The wire passes downwards, and a reinforced sheet c is formed by the two streams b of glass uniting with the wire. In order to prevent the formation of air bubbles in the sheet and to cause the glass to unite with the wire, air is exhausted from the space 11 within the slab. A chamber formed by walls 6 encloses the lower part of the slab and is heated by burners 23. The hot gases from these burners regulate the condition of the glass flowing down the slab and impart a fire polish to the finished sheet.
