Title: Improvements in or relating to cylinders and cylinder heads of internal combustion engines
IPC: F01L7/08
Filed: 1942-05-27
Abstract: 557,564. Cylinders ; valves. ASPIN, F. M. May 27, 1942, No. 7163. [Classes 7 (ii) and 7 (vi) The cylinder head 16 with rotary conical valve 20 therein is formed as a pluglike unit and secured in a socket 12 integral with the end of the cylinder by studs passing through a flange 17. A liner 13 may be provided in the cylinder, and a sealing ring 19 between this and the plug. The larger end of the valve is always exposed to the cylinder and its tapered surface bears against a similar surface on the plug-like unit forming a gas-tight-joint. Preferably the valve is constructed as described in Specification 463,412. The cylinder may be liquid-cooled as shown, or formed with fins and air-cooled. The valve is provided with a bearing 21, a driving wheel 22, and a seating-spring 23.

Title: Improvements in or relating to methods and apparatus for hot rolling metal
IPC: B21B1/30
Filed: 1936-03-13
Abstract: 471,928. Rolling. RUSSELL, G. A. V., and IMPERIAL CHEMICAL INDUSTRIES, Ltd. March 13, 1936, Nos. 7671 and 12204. [Class 83 (iv)] [Also in Group XII] Metal strips or sheets are reduced in thickness in a batch by hot rolling, are cooled, reheated and uncoiled in succession and reduced by hot rolling preferably through the same rolls. A 4" slab from a furnace 1 is reduced to 0À3" in about 10 passes through a three-high or a reversing universal mill 3, then coiled at 6a and carried through a tunnel furnace and on a conveyer 7 and a trolley 9 to an uncoiler and descaler 10 which feeds it into a four-high or other non-severing intermediate rolling mill 11. The strip is coiled at 15 and passed through the U-shaped furnace 16, is again uncoiled at 10, repassed through the mill 11, four such repeated passes and reheating reducing it to 0À08." The reheater 16 accommodates a number of coils at once. The coiled strip is then conveyed by trolley 32 to a second U-shaped reheater furnace 33 through which it is conveyed to an uncoiler 35 and passed through four-high finishing rolls 36, coiled at 40, again passed through the furnace 33 and the rolls 36 being thereby reduced to 0À049". The strip is then discharged on to table 42 the free end of which is dropped for this purpose, or it may be coiled at 40 and discharged. The furnace 16, Fig. 2, is formed with coil-holding ledges 24 from which the coils are lifted by the raising up of cars 22 which are traversed through the furnace on rails 19 by reciprocating mechanism 25, Fig. 4, driven electrically or hydraulically. The car mechanism closes the furnace bottom by oil, sand, &c. seals 28, Fig. 3. The adjacent ends of cars are also sealed at 29, and a movable sealing damper 30 is attached to the end car at the entrance and exit of the furnace. Instead of lifting the cars, independent means may lift the coils on and off the cars 22. In an alternative conveyer two rows of coils may travel on idle rollers and traversed along by reciprocating fingers which are raised to engage and traverse a coil and then lower and move back for the next push. Straight furnaces with transport means may replace the U- shaped furnaces. In Fig. 8, the furnaces 72, 79 for the reversing finishing mills 67, receive coils pushed therein by the charger 74 until the furnace is full, when the furnace is rotated on its turntable through 180‹ to allow discharge of the coils for re-rolling by a ram discharger 77. In this case the roughing rolls 61 supply work to either of two sets of finishing rolls 67 and furnace apparatus &c. In a further alternative the furnaces are stationary and receive up-ended coils from a swinging and traversing arm type of conveyer which also takes them out of the furnace in the same order.
