Title: Improvements in or relating to coke oven heat distribution
IPC: C10B21/20
Filed: 1953-11-16
Abstract: 746,199. Coke ovens. KOPPERS CO., Inc. Nov. 16, 1953 [Jan. 28, 1953], No. 31743/53. Class 51(2). Production of high quality foundry coke in a conventional underfired horizontal coke oven battery is facilitated by top firing with coke oven gas at selected regions in the battery to produce uniform oven heat distribution. The invention is shown applied to an underjet oven of the CoffÚe type in which each heating wall is divided into two sets of flues 14 with gas nozzles 16 supplied from rich gas ducts 20, each set of flues being associated with a corresponding regenerator, the said flues 14 discharging into a top horizontal flue 24 which communicates with a top horizontal cooling flue 26 through damper controlled ports 28. The flue 26 has a dividing brick 50 midway between the ends, and also has access flues 34. The top heating is provided for by running a rich gas, e.g. coke oven gas, main 38 centrally across the battery, and forming it with a branch pipe 42 at each heating wall. Each branch pipe is valve controlled, and has a nozzle 46 extending into a central access flue 34. The dividing bricks 50 are removed and the bricks 32 slid off the ports 28, so that the rich gas introduced through the nozzles 46 will flow through the upper flues in alternating direction in accor, dance with the alternating direction of flow in the connected vertical flue groups. Specification 175,902, [Class 51(ii)], is referred to.

IPC: F41F3/10
Filed: 1920-03-20
Abstract: 164,281. Turcan, J. March 20, 1920. Ordnance for submarine discharge; pneumatic. - Consists in a pneumatic gun 1 with a lateral loading- opening 4 and a hinged spring-pressed muzzle door 2 projecting through the bow of a submarine. Compressed air is admitted by a pipe 20 in rear of a piston 6, which has a second head 8 separated by a spring 7 from the piston 6. The piston-rod 5 projects rearwardly and is connected by a cross-head 9 to a longitudinal rod 10. When the pressure air is admitted, the rods 5, 10 move forwards, and a wedge-plate 19 on the rod 10 forces apart two hinged projectile-retaining arms 15, and the outer end of the rod forces open the door 2. The projectile is expelled either by a cushion of air, which forms between the piston head 8 and the base of the projectile, or by the energy of the spring 7.

[Also in Group XXXVIII] A tracer-controlled machine tool, such as a lathe or boring and milling machine, comprises valve means 1020 for controlling at least one reversible rotary air motor M detachably connected to a normally hand-rotatable feed shaft 59 of the machine tool and electric means connecting the tracer and the valve so as to electrically actuate the valve in response to displacement of the tracer. The tracer 1000 is mounted for axial and transverse movement in a housing 1003 adjustable vertically on a bracket 1004 carried by the spindle head C of a boring and milling machine. The tracer has electrical contacts, such as described in U.S.A. Specification 2,372,604, which actuate valves to control two air motors. The motor M is a swash-plate motor connected to the hand crank connection 59 for moving the saddle E. The motor is normally supplied with air through pipes 1022, 1023 to both sides thereof, thus locking the drive. The speed of the motor is controlled by a valve 1028 in the exhaust line 1027, to which one or other of the supply pipes may be connected by the tracer-controlled valve 1020. The motor drives through reduction gearing R and a collet-type clutch 1040 which can be disengaged to enable the motor to be inoperative without the need of removing the motor housing 1033 and mounting plate 1034. In operation, the table F is traversed across the saddle which is controlled by the tracer. Subsequent traverses are then made when the cutter and tracer have been adjusted by vertical increments. A second motor can be fitted to a crank-shaft 83 to control the cross-travel of the table. In a modification, the control valve means are located on the supply, instead of the exhaust, side of the motor. A motor may also be fitted to the crank 96 controlling vertical movement of the spindle head. Or a motor can be fitted to the spindle feed wheel 202 so that the cutter moves to- and-from the work instead of vice versa. The motor and tracer assembly may be regarded as an attachment to convert a machine for automatic copying.
