Title: IC engine with sparkless ignition - has nozzle with diffusor from cylinder to small chamber where fuel mixture vortex causes ignition
Inventor: ZIEGLER HEINRICH
IPC: F02P23/02
Filed: 1979-06-22
Abstract: The arrangement (4) is intended for igniting the fuel-air mixture in a combustion engine. During the compression of the mixture in the combustion chamber (2), part of this mixture passes into a separate ingnition chamber (10) via a connecting passage (14,15) which is contoured such that a vortex is created and the mixture heated above its ignition temperature, thus initiating ignition. The passage may comprise a nozzle orifice (14) with a diffusor (15) leading into the ignition chamber (10). The chamber volume is considerably smaller than that of the chamber (2), whilst the diffusor causes the flow to break away from its wall to produce the ignition vortex.

Title: Complex wind force driven plant - has lightweight shaft supports and rotary supports on slewing crane in roller bearings
Inventor: LIES ALEXANDER
IPC: F03D13/20
Filed: 1979-10-16
Abstract: The combination of linear supports for wind wheels and combined wind rotors provides considerable constructional savings, both in equipment and size of foundations. This results also in better wind force utilisation, resulting in approximately 30 times higher current generation. Ten wind wheels are vertically stacked so that the upper ones provide a higher utilisation of the rotors. In this manner the shaft output of the wind wheels is coupled to a horizontal shaft, driving powerful generators and compressors. The wind rotors are of conical design for speed stabilisation. They utilise the highest wind forces and thus contribute to the system stability.

Title: High voltage insulator has mineral filler exposed at surface - to minimise tendency of conducting paths to form
IPC: H01B17/00
Filed: 1980-12-15
Abstract: A high voltage insulator is of plastics contg. a mineral filler. At the surface of the insulator, particles of the filler are at least partially exposed. A conventionally moulded insulator may be mechanically treated, for example by sand blasting, machining or the like to expose the filler particles. In another method, a layer of filler is applied to the insulator, but the particles are only partly embedded in the plastics. For various types of high voltage insulators, e.g. support insulators with or without ribs or disc-type insulators for metal-encapsulating, compressed gas insulated high voltage installations. The effect of the projecting filler particles at the surface is greatly to reduce the risk of conducting paths being formed along the surface by carbon deposits when arcing occurs.

Patent DE-3147615-A1 (DE)
Title: Nuts with tapered shoulder
Inventor: MITSCH HERBERT
IPC: F16B33/00
Filed: 1981-12-02
Abstract: The nuts with tapered shoulder, according to the invention, permit said nuts, at inaccessible points, to be fixed before mounting, by means of the conical shoulder, by pressing into correspondingly dimensioned bores and, at the same time, to be secured, with respect to automatic loosening, by tightening the screws. Up until now, use has had to be made, at such points, of weld nuts, rivet nuts or punched-in nuts, and this required additional manufacturing devices and operations. Normal screw connections having an anti-loosening means required additional parts such as spring lock washers, spring-shift washers or expensive self-locking nuts. The possible applications are virtually unlimited since even the nuts of the conventional type may be used. Otherwise, they are used in all cases where, in the case of one-hand mounting or inaccessible points, normal fixing of the nuts by hand during the screwing operation is not possible and as anti-loosening nuts without additional securing washers. Figures 1-4 of the patent drawing show an exemplary embodiment and application, and Figures 5 and 6 show a nut according to the invention having a toothed conical surface in order to increase the anti-loosening action. <IMAGE>
