Patent DE-3828805-A1 (DE)
Title: Star spark plug for internal combustion engines
Inventor: VUJOVIC GEORG DIPL ING
IPC: H01T13/46
Filed: 1988-08-25
Abstract: It is known that combustion takes place only incompletely in spark ignition engines; if the fuel were to be burnt completely, said fuel being composed in a known manner essentially of hydrocarbons, the exhaust gases would comprise only carbon dioxide and water vapour. The "star" spark plug with its three ignition electrodes is intended to improve combustion significantly and thus to reduce to a minimum the hazardous materials which are severely environmentally unfriendly. Under some circumstances, the ignition electrodes could be installed at three different points in the combustion chamber of a spark ignition engine, and thus even more complete combustion could be achieved.

Patent DE-3835060-A1 (DE)
Inventor: TOKUNO MASATERU
IPC: B31F1/24
Filed: 1988-10-14
Abstract: A corrugating machine has a tension control circuit 20 and 30 for adjusting the tension of a single faced corrugated fiberboard A on its way from a single facer 2 to a double facer 12 within a suitable range. Reference speed signals are given to the double facer (12) and the single facer (2) to drive them at reference speeds. If the actual tension of the single faced corrugated fiberboard A detected by a detector (31) gets too large or too small compared with a predetermined optimum tension, a comparator (35) gives a correction signal to adjust the reference speed signal for one of the single facer (2) and the double facer (12) and thus to accelerate or decelerate its speed, while keeping the other driving at the reference speed. The tension of the single faced corrugated fiberboard can thus be adjusted to a desired level. <IMAGE>

Patent DE-3842051-A1 (DE)
Title: Device for connecting pieces of furniture
Inventor: GOETTFERT JOHANN
IPC: A47B87/00
Filed: 1988-12-14
Abstract: The subject matter of the invention is a device for the reversible connection of two pieces of furniture (7 and 8 or 8 and 9) which are to be fitted together in a flush manner, in particular kitchen cabinets, having planar abutment surfaces (7.1 and 8.1 or 8.2 and 9.1), respectively. The prior art is the alignment of the pieces of furniture which are to be fitted together, the adjustment thereof and the use of screw clamps and the mutual screw-connection of the pieces of furniture. The disadvantage with this assembly process is the high outlay in terms of time and labour. The object of the invention is thus to shorten the assembly times without detracting from quality. This object is achieved by at least one releasable, dovetail-like connection (10), of which the male part (14), right up to the projecting member (48), and the female part (12) are let into the abutment surfaces (7.1, 8.1, 8.2, 9.1) at mutually opposite locations of the connected pieces of furniture (7 to 9). The advantage with this is the large reduction in assembly time along with even better quality of the connection, which, by virtue of the preparation work by the furniture manufacturer, can be carried out by auxiliary workers. <IMAGE>

Patent DE-3907785-A1 (DE)
Title: Plastic pipe and process for its production
Inventor: ROSENBERG GERHARD
IPC: B29C48/09
Filed: 1989-03-10
Abstract: Water lines, air lines and similar lines comprising plastic piping, for example polypropylene piping, are being used increasingly in sanitary and heating installations in residential and office buildings as well as industrial constructions, since plastic pipes are the most resistant to aggressive water in comparison with the copper and steel pipes previously used mostly frequently for such installations. A disadvantage of plastic pipes is that of the large wall thicknesses prescribed for the cold-water and hot-water area, depending on the pressure stage. To achieve higher strength with a reduced wall thickness in comparison with the known pipes, the pipe 1 produced from polypropylene has worked into the pipe wall 2 a reinforcing fabric of natural or synthetic fibres with diamond-shaped meshes 4, underlaid with longitudinal filaments 5 of natural or synthetic fibres. The reinforcing fabric 3, wound up onto an extruded core tube strand 6, is sheathed by a coextruded outer jacket 7. <IMAGE>

Patent DE-3910606-A1 (DE)
Title: Process for preparing dyes of the dibenzopyrenequinone series
Inventor: STEUERNAGEL HANS HELMUT DR
IPC: C09B3/52
Filed: 1989-04-01
Abstract: The production of vat dyes of the dibenzopyrenequinone type is conventionally based on 1,5-dibenzoylnaphthalene. To prepare this starting material for the oxidative ring closure, naphthalene is dibenzoylated in aluminium chloride using a benzoyl chloride excess of 70%. When the naphthalene derivative produced is isolated, this excess benzoyl chloride has to be inconveniently washed out in the form of benzoic acid. In addition, for the subsequent cyclisation, the resulting dibenzoyl compound, which still contains many by-products, must first be brought to the required purity (>/=de 95%) by reprecipitation from organic solvent. The invention now provides a one-pot process starting from naphthalene. In this process, the dibenzoylation of the naphthalene is carried out with an excess of only 5% of benzoyl chloride, and the melt of 1,5-dibenzoylnaphthalene is then - without intermediate isolation thereof - subjected to the oxidative ring closure reaction, bromination and finally work-up to the desired dye.

Filed: 1989-04-08
Abstract: A conventional positive-displacement pump or a conventional positive-displacement motor has, even if to a limited extent, certain disadvantages due to production, above all at the corner region of the cuboid sliding spool. In operation, sealing problems can also arise in these corner regions. In order to counteract this, it is provided that instead of a cuboid sliding spool provision is made in each case of one or, possibly, two cylindrical working pistons (9b, 9d) which lie offset by 90@ relative to one another in two planes and are arranged movably in cylinder bores (12, 15) which can be produced appropriately without any problem. The at least one or two working pistons (9b, 9d) are connected in a driving manner to an axle body (4) of a shaft (17) via a coupling member (9a). The positive-displacement pump or the positive-displacement motor is particularly suitable for hydraulic fluids. <IMAGE>
