Patent DE-3100619-A1 (DE)
Title: Forming the ignition spark in internal-combustion engines which operate in accordance with the Otto principle and have internal combustion
Inventor: OANEA ALEXANDER DIPL ING
IPC: H01T13/22
Filed: 1981-01-12
Abstract: According to the invention, the two-electrode spark plug which is used to form the ignition spark is replaced by two electrode bodies which are separate from one another and project into the combustion chamber in the engine cylinder. The distance between the two electrode tips is 7...30 mm and the voltage of the ignition current [sic] which is used to form the ignition spark between these two electrode tips is 70,000...300,000 volts. The actual values of the electrode tip separation and ignition-current [sic] voltage are matched to one another and are defined as a function of the shape of the combustion chamber, the size of the cylinder bore, the fuel-air mixture ratio and the compression ratio. In order to ensure the ignition spark jumps over from the positive electrode to the negative electrode and that the ignition spark is not deflected by other electrically conductive parts in the combustion chamber, the negative electrode is subjected to continuous electrostatic charge. The advantages of the invention are:   a) shorter overall duration of the combustion process as a result of combustion starting from a long ignition spark instead of a point-source ignition spark. b) Reduction in residues having hazardous material properties in the exhaust gases as a result of improved propagation of combustion in terms of speed and space. c) Achievement of constant engine powers with weaker fuel-air mixture ratios, that is to say a lower specific fuel consumption.

On each of the two sides of the piston, the cylinder possesses an orifice, through which either the pressure medium or a vacuum can be introduced into the cylinder. The cylinder either can be parallel to the guide rail or else can also be arranged at a distance from the guide rail. In the latter case, the cable runs between the cylinder and the guide rail in Bowden-pull hoses in a manner known per se.
Patent DE-3106338-A1 (DE)
Title: Paint brush holder
Inventor: MONHEIMIUS HARTMUT
IPC: B44D3/12
Filed: 1981-02-20
Abstract: In known paint brush holders, the clamping of the paint brush is achieved by means of clamping nuts. The object of the invention is to provide a paint brush holder which operates in an infinitely variable and low-wear manner without clamping elements. This object is achieved, according to the invention, in that the handle (1) of the paint brush holder is provided with an infinitely variable quick-action clamping apparatus. As a consequence of this measure, as the drawing shows, the clamping operation is simplified so that it is sufficient, in order to clamp the paint brush, to apply a gentle pressure against the pressure sleeve (9) in order to allow the clamping ring (4) to slide out of the slot (3) so as to be able to receive the handle of the paint brush. If the handle of the paint brush is now introduced into the clamping ring (4), the pressure sleeve (9) is released, the heavily prestressed spring (6) pulling the clamping ring (4) into the slot (3) and the paint brush handle being firmly pressed into the notch (2). In order to remove the paint brush from the paint brush holder, it is sufficient to exert a gentle pressure against the pressure sleeve (9), the clamping ring (4) sliding out of the slot (3) and releasing the paint brush. <IMAGE>
