Title: Ketone prepn. from carboxylic acid halide(s) - by reacting with aluminium alkyl cpds. in methylene chloride at moderate temp.
Inventor: SPIELMANN WERNER DIPL CHEM DR
IPC: C07D333/22
Filed: 1979-10-12
Abstract: Prodn. of ketones by reacting carboxylic acid halides with Al alkyls or alkyl-Al halides, opt. in the presence of Al halides, in CH2Cl2 as solvent, and decomposing the resulting ketone complex in H2O, is improved by carrying out the reaction at 20-100 degrees C (pref. 30-60, esp. 40 degrees C) opt. under superatmospheric pressure. The prods. include cpds. useful as intermediates or end-prods., e.g. in the fields of dyestuffs, plant protection agents, pharmaceuticals and solvents. Compared with prior art processes effected at 0 degrees C, the present process reduces cooling costs without the expected loss of yield; in some cases the yield is even increased.

Patent DE-3012857-A1 (DE)
Inventor: KUENNE WOLFGANG ING GRAD
IPC: B43M7/02
Filed: 1980-04-02
Abstract: An apparatus for removing the content from envelopes having two adjacent edges opened by slitting or cutting is equipped with two facing suction devices. At least one suction device is movable perpendicular to the envelope plane for separating the envelope. During the operating phase, one suction device is movable with respect to the other in the envelope plane in order to effect a relative movement between the envelope and the contents of the envelope. This facilitates removal because the envelope held by the suction device is additionally deformed, i.e., given a corrugated configuration by the movement in the envelope plane. As a result, easy removal of the envelope content is possible.

Title: IC engine with exhaust gas turbine generator - having output used in electrolysis of water adding burnable gases to fuel mixture inlet
Inventor: GAIL JOSEF
IPC: F02B43/10
Filed: 1980-05-06
Abstract: The exhaust gas from a four stroke engine is used to drive a gas turbine (9) coupled to a generator (12). The generator output is connected to electrodes (14,15) in a water tank (13) from which hydrogen and oxygen are collected as the water decomposes by electrolysis. These gases are ducted through separate tubes (16,17) to the inlet manifold (6), and are subsequently burned in the cylinders (3) together with the normal fuel and air mixture. Keeping the gases separate until they are fed into the manifold prevents the formation of an explosive mixture. The addition of the gases to the fuel inlet improves the efficiency of the engine. The proposed system is an alternative to using an electric motor, fed from the generator on the engine drive shaft.
