Title: Improvements in and relating to a method of and apparatus for controlling the torqueof internal combustion engines or turbines
IPC: F02N9/04
Filed: 1937-09-09
Abstract: 485,970. Motor power plant. JANICKE, H. Sept. 9, 1937, No. 24609. Convention date, Sept. 16, 1936. [Class 110 (iii)] [Also in Group XXVII] For increasing the torque of an internalcombustion engine or turbine, for example when starting under load, the working chambers are supplied with compressed gases from the working chambers of a second engine or turbine running at a higher speed. The second engine as a rule performs no mechanical work during this operation, and the compressed gases used may be compressed air withdrawn from the second engine before combustion begins therein, or may consist of the combustion gases of the second engine. In the latter case, they are delivered to the first engine after combustion has taken place therein. During normal running, the two engines are coupled together to drive the load jointly. As shown, a coupling 33 connects the shaft of the engine 1 permanently to the load, and a clutch 23 between the shafts of the engines 1, 2 is disengaged when the engine 2 supplies compressed gases to the engine 1. The engines shown are two-stroke engines with piston-controlled inlet and exhaust ports 11, 12, 14, 15 and with fuel-distributing means 3, 4, such as pumps. A pipe 37 conveying compressed gases from the engine 2 to the engine 1 for starting &c. is provided with valves 13, 16 actuated by cams 17, 19 and levers 18, 20 brought into and out of operation by sliding fulcrum blocks 21, 22 connected to a manual lever 24. The fuel-distributing devices 3, 4 and the clutch 23 may also be controlled from the lever 24 through links 29, 30, 25. By means of a control lever 9 for a governor 5 acting on the fuel-supply device 3, the speed of the engine 2 may be brought to a maximum to enable the gases drawn therefrom to exert a high torque in the engine 1. The fulcrum blocks 21, 22 have inclined faces 35, 32, so that the time of opening of the valve 16 is increased during the range of adjustment b, c of the lever 24, the valve 13 then being fully open. In a modification, the blocks 21, 22 are interchanged and the time of opening of the valve 13 is increased during the range b, c, the valve 16 being fully open ; and a governor on the shaft of the engine 1 is arranged to act on the spring of the governor 5, so that as the speed of the engine 1 increases that of the engine 2 increases up to a maximum. The manual control lever 9 for the governor 5 is used to equalize the speed of the engine 2 with that of the engine 1 before the clutch 23 is engaged. Alternatively, the clutch 23 may be engaged automatically by means actuated from a governor on the engines attaining a suitable speed. When running under low load, one of the engines may be uncoupled and stopped.

Title: Production of titanium dioxide
IPC: C01G23/07
Filed: 1965-06-11
Abstract: Titanium dioxide is produced by heating titanium tetrachloride to at least 300 DEG  C. by a plasma flame generated by electrical energy and reacting the heated titanium tetrachloride with oxygen or free oxygen-containing gas. The plasma flame is generated by passing a working gas between electrodes or through a high frequency coil while an electrostatic, electro-magnetic or arc discharge ionizes from <PICT:1088924/C1/1> 0.01 to 1% of the gas during its passage there-through. The working gas comprises titanium tetrachloride, oxygen, carbon dioxide, carbon monoxide, chlorine, and/or inert gases.  As shown in Fig. 1, the working gas is introduced at 4 into a reactor and passes through an arc struck through a water-cooled cathode 2 and an anode 3.  Oxygen and titanium tetrachloride are admitted at 5 and 6 respectively whence they are heated by the plasma flame and react to form titanium dioxide.  Additional oxygen or titanium tetrachloride is introduced at 7. As shown in Fig. 3, the plasma flame is generated <PICT:1088924/C1/2> in reactor 21 by passing the working gas 25 over the tip 28 of an electrode 24 connected to an electric oscillator 22.  Titanium tetrachloride and oxygen are introduced at 26 and 27 respectively. In a third reactor the working gas is introduced tangentially into a silica tube and passed through a high frequency electromagnetic field provided by an induction coil surrounded by the tube (see Fig. 2, not shown).

To initiate air filtering a "start" button 47 is depressed and current flows through the starter coil 43 of the fan motor 13, and to terminate a filtering run a "stop" button 48 is depressed resulting in the starting of a motor driven clock 51, Fig. 4, of a timing device 50 and the rotation of a cam 52, (Fig. 5, not shown) and energization of a relay 59 which breaks top relay contacts 61 and thereby opens the starter coil circuit 43 of the fan motor 13. In rotating, the cam 52 first opens a normally closed switch 57 and ensures supply of current both to the clock motor and to relay 59 when "stop" button 48 is released. After about two minutes cam 52 closes the normally open switch 58 to pass energizing current through the shaker motor starter coil 46 by which time the fan will have come to rest. After a cleaning period of about 30 seconds the cam 52 reverses switch 58 to its original open position, but the shaker motor 38 is not stopped until a switch 63 in parallel with switch 58 is opened by a cam so positioned on the shaker motor shaft that the filter bags assume their distended positions. The cam 52 then continues to rotate for a further two minutes at which time switch 57 is closed, relay coil 60 is de-energized and the clock stops to complete a cycle.
