Title: Fuel injection control for Diesel engines - has linkage with cam profile to vary quantity according to speed and load
Inventor: ZELLER HELMUT
IPC: F02D1/02
Filed: 1979-09-27
Abstract: A spindle is turned in proportion to engine speed. A blade fixed to it moves a rod which varies the injection timing. The blade also moves two slotted bars. One of these moves the end of a control lever to reduce the fuel quantity with increasing speed at full load. The other moves a pin on an intermediate lever which pushes the control lever to increase the quantity with increasing idling speed. The movement of the control lever is limited by a stop on an arm. The arm runs on a cam attached to the blade. This varies the characteristic according to the load.

Inventor: TOLLEY WILLIAM KENT
IPC: C22B34/12
Filed: 1979-11-02
Abstract: Ti values are recovered by roasting, the crushed source e.g. ilmenite at 600-1000 degrees C in presence of H2 and/or CO gas, leaching with hydrogen halide at up to 110 degrees C sepg. gangue and cooling solubilised metal halides to ppts. FeCl2. The leach liquor is then treated at 70-100 degrees C with 2.5-50 times stoichiometrically required amount of Fe2O3 to convert Ti halide to TiO2. The leach liquor is agitated and solids are recovered and mixed with a second leach soln. contg. sufficient Ti halide to consume remaining Fe2O3. TiO2 is recovered. The ore e.g. ilmenite is crushed to -35 mesh and roasted at 600-900 degrees C in a 50-50 CO-H2 gas mixt. for 0.25-2 hours., then leached with HCl at 80-100 degrees C for 0.25-1 hour. The leach liquor is cooled to 0-90 degrees C to cause crystillisation of FeCl. The excess of Fe2O3 is then added and reaction allowed to proceed for 1-10 minutes after which solids are removed and mixed with the second leach solution.

Title: Reciprocating internal combustion engine - has external eccentric rotor compressor to increase volume charged into cylinder
Inventor: HEIDENESCHER FERDINAND
IPC: F02B75/32
Filed: 1980-01-12
Abstract: The engine has a piston (7) reciprocating in a cylinder. The piston rod (11) moves a shaft (12) which turns two eccentric wheels on either side of it. This movement is transmitted to a large eccentric rotor (15) at the end of the piston rod. The rotor compresses air between itself and its casing (17) and forces it through a non return valve (13) into a chamber (10) on the underside of the piston. The air passes from this through automatic valves (9) into the combustion chamber (2) above the piston. The exhaust from the combustion chamber is through a valve (3) operated by a pushrod (5) and rocker arm (4).

Title: Ambient light level sensitive electronic flash - uses control circuit to reduce light level necessary for production of flash terminating signal when high ambient light is sensed
Inventor: WISST OTTO
IPC: G03B7/28
Filed: 1980-02-28
Abstract: A flashtube (18) is quenched when a light-responsive integrating circuit (15) has received a requi red amount of light. The amount is reduced if the ambient light exceeds a certain level. A light-level sensing circuit (14) measures the intensity of the ambient light. A threshold-setting circuit (22,32,34), responsive to the sensing circuit (14) causes the amount of light needed to be sensed by the integrating circuit (15). The circuit is used for the terminating the flash in bright ambient light to be less than the amount of light required to be sensed for terminating the flash in low ambient light. Alternatively, the integrating circuit has two capacitors, one of which is switched out when ambient light is bright. A single element may be used to sense both the ambient light and the flash light.
