Title: Fuel injection device with supply and injection pumps - injection pump bypass with non-return valve maintains constant pressure
Inventor: FELDINGER MARTIN DR
IPC: F02M63/00
Filed: 1973-09-19
Abstract: The injection piston pump has an overflow and its working chamber receives fuel from the supply pump via a pressure storage chamber and a suction line with pressure limiting valve. The pump is connected, via a pressure valve and a pressure line, with an injection valve. The pressure line from the pressure valve to the injection valve receives fuel at constant pressure direct from the supply pump, via a non-return valve, the pressure being in excess of the highest pressure which automatically establishes itself in the pressure line. The bypass may alternatively contain a throttle section instead of the non-return valve. The pressure storage chamber may be connected with the pressure line and with the suction line via a second pressure limiting valve set for a higher pressure than the first.

Title: Distillery control unit attached to a final condenser - automatically separates the distillate fractions according to instrument settings
Inventor: SPROLL EBERHARD
IPC: B01D3/42
Filed: 1974-07-05
Abstract: An attachment for the final condenser of a still, has an inlet to be connected to the condenser outlet, followed by 2 changeover valves controlled automatically by monitors, responding to the parameters of the distillate, such, as, volume, weight, time, or specific gravity, for separately regulating the flow of the first, main and end fractions. The nominal value of the parameters can be preselected by adjustable devices, and the flow of the distillate is distributed from a column with an annular overflow trough, from which 2 branch lines drain from different levels. One of the lines feeds the changeover valves and outlet pipes. The other branch feeds the first fraction vessel in which a float lifted by the distillate closes a circuit energising one of the changeover valves. The overflow and first fraction vessels may have solenoid controlled shut off valves similar to the changeover valves or have manually operated valves. In the overflow vessel a hydrometer is provided which, as the density rises, energises the other changeover valve. The operative is relieved of all tasks except to see that the various fractions are collected in the appropriate vessels.

Title: Producing chipboard having coarse-fine layers - by scattering layers of coarse-fine chips onto moving base layer
Inventor: SELCHO BERTHOLD
IPC: B27N3/14
Filed: 1975-02-24
Abstract: Chipboard or fibreboard having >=1 layer of coarse chips/fibres and >=1 cover layer of fine chips/fibres is produced by continuously scattering measured amts. of the chips/fibres which may already contain the binder, onto a moving base layer. During the transport of the base layer in one direction a fine layer and a considerably thicker coarse layer are scattered, and a supply of fine chips/fibres is simultaneously collected. During the transport of the base layer in the opposite direction an additional coarse layer is scattered, if required, over the formed web, and then a fine layer is scattered over the coarse layer from the collected supply of fine chips/fibres. Method gives very uniform layers of fine and coarse materials. The fine layers may have a varying thickness. The thickness of the upper fine layer can be easily controlled. Boards pressed from the resulting webs have a very smooth surface.

Title: Welding with consumable electrode using copper contact nozzle - contg steel bush to reduce nozzle wear
Inventor: ABEL GERD
IPC: B23K9/12
Filed: 1975-03-13
Abstract: Contact nozzle for inert gas welding using a consumable electrode, the nozzle body being made of a material softer than the electrode wire, and pref. of copper with a constant bore for the electrode, and a connecting piece for attachment to a welding pistol. The novelty is that, apart from a small zone in the region by the nozzle outlet, the bore of the nozzle is formed by a bush inserted in the copper body, the bush being made of a material which is harder than the consumable electrode, and pref. consists of steel. The composite nozzle is pref. made by squeezing the copper body round a steel bush located on a mandrel. Although copper provides a very satisfactory electric contact, grooves are very easily scratched in its bore, dirt collects in the grooves, interfering with the welding operation and shortening the nozzle life. The steel bush avoids this problem.
