Title: Hard ashless charcoal briquettes - made from electrolytically purified carbonaceous materials
Inventor: VELOSO ALBERTO E
IPC: C10L9/02
Filed: 1972-09-07
Abstract: Briquettes having high heat values are made by process in which impurities in the feed materials are electrolytically removed before being shaped into briquette form. Process comprises immersing finely divided carbonaceous material in an electrolyte (in a porous container) together with electrodes in an electrolytic cell, and applying a p.d. to the electrodes thus providing a source of ions for reaction with the impurities in the carbonaceous matter. The carbon is then washed with hot H2O, dried, compressed into briquettes at >550 degrees C and >200 tons/in2, and cured in CO2 at >50 tons/in2 for >20 hrs. The pref. electrolyte is 5-40% aq. H2SO4 and the pref. carbonaceous material is a vegetable source freed of cellulose, carbohydrates, lignans etc., by contact with 50-100% H2SO4. As an extension to the process the carbon may be further purified by treatment with 10-20% soln. of HF to remove silicate materials. The electrolytic cell is operated at 3.5-14 volts and 40-80 amps/ft2 for >=10 mins.

Title: Fuel vaporising system for I.C. engines - fuel mixture is compressed heated and blown into inlet port
Inventor: AUGUST PAUL DIPL ING DR
IPC: F02B17/00
Filed: 1973-08-11
Abstract: The process transforms a liquid fuel and air mixture by two consecutive stages into a vapour suitable for a complete combustion to avoid excess harmful exhaust emission. A specially constructed compressor pump is timed by means of a connecting rod or cam to blow a heated air fuel mixture into the engines inlet port at each cylinder in order to form a strata charge. The engines inlet and exhaust valves are arranged in the cylinder head with the inlet valve offset from the combustion chamber. In the case of a two-stroke engine the compressed mixture is blown into the transfer port. A heat exchange unit is provided between the compressor outlet and engine intake port to heat the fuel air mixture to almost vapourisation temp. Air only is drawn in at the engine intake. Fuel and air and/or an exhaust gas is drawn in by the compressor from a carburetor near the end of the compressor intake stroke.

Title: Flywheel powered household appliance - with drive motor acting as generator for using flywheel energy for appliance
Inventor: STEINRINGER GUENTER
IPC: B60L50/30
Filed: 1974-05-06
Abstract: The household appliance, e.g. floor cleaner/polisher, is fitted with a flywheel which is driven by an integral electric motor via a friction clutch.

Title: Gradient seam conveyor anchorage - safety valve with short circuit valve responds to prop setting pressure changes
Inventor: AMLING FRIEDEL
IPC: E21F13/10
Filed: 1974-07-08
Abstract: A tensioner is secured parallel to and on the conveyor and an adjustable steel beam fixed to a support at right angles to the conveyor, with hydraulic cylinders to effect spatial adjustment.

Title: Exterior mounting of spare wheel - has depression behind bumper for low mounting clear of fresh air inlet grille
Inventor: BRECHT WILHELM
IPC: B62D43/02
Filed: 1974-12-14
Abstract: The space behind the front bumper (2) of the flat fronted vehicle has a profiled depression (3) into which the spare wheel (4) can be stacked in a vertical, flat setting.
