Title: Vacuum cleaner nozzle with suction tube connection, sliding sole and rotating brush cylinder
Inventor: OBBELODE WILFRIED
IPC: A47L9/04
Filed: 1984-04-19
Abstract: In a vacuum cleaner nozzle with a suction tube connection, sliding sole and rotating brush cylinder and with a turbine wheel, to which the suction air flow is admitted via a suction channel, as the drive for the brush cylinder, a foot switch is arranged on the vacuum cleaner nozzle. Using the foot switch, a control device for the suction air flow in the suction channel of the turbine wheel is either switched on or switched off, as a result of which the suction air flow is passed over the turbine wheel either in a non-conducted or concentrated manner. It is thus achieved that, on the one hand, the turbine wheel or the brush cylinder rotates with reduced performance and, on the other hand, with full performance without the suction performance dropping at the nozzle.

Patent DE-3422143-A1 (DE)
Inventor: BILLE JOSEF PROF DR
IPC: G01N21/64
Filed: 1984-06-14
Abstract: This invention enables examination of semi-conductor chips either on a planar basis or on a three-dimensional basis to determine the characteristics of the chips. Laser light is passed through a first pinhole and is focussed on a wafer. The light reflected from the wafer is passed through a second pinhole and is focussed on a photomultiplier. The focal length between the first pinhole and the wafer is the same as the focal length between the second pinhole and the multiplier. This arrangement provides for a high signal-to-noise ratio to be produced and image information data to be provided within minimal time lags such as a small fraction of a second. An electrically controllable active mirror operable within the beam-shaping optics of the scanning field may be included to displace the plane of the examination field. This active mirror may be controlled to assume the shape of different types of mirrors including a planar mirror. By controlling the operation of the active mirror, the etchings of first materials on the wafer and the depositions of other materials on the wafer may be examined at different depths. The control of the active mirror may be provided at a different frequency than the frequency of the light providing for the examination of the wafer. The visual portion of the light spectrum from the laser may be further processed to determine such parameters in the wafer as the distribution of photoresist residues on the wafer.

Patent DE-3434710-A1 (DE)
Title: Injection rotary engine for liquid or/and gaseous fuel, mixed with air or/and oxygen
IPC: F02C5/04
Filed: 1984-09-21
Abstract: For improved utilisation of fuels, the running parts (rotor, piston, etc.) of the engine should not perform a reciprocating movement and therefore have no dead centres or dead centre positions, but perform a purely circular movement (for example, the Wankel engine moves in the shape of an "8") and act on the running part in the same direction of rotation both during injection and during the working cycle. This results in less component wear, longer service life and, due to improved utilisation of the fuel, greater protection of the environment. Due to the arrangement of the combustion chambers, each offset by 180 DEG , any unbalance is avoided or greatly reduced and with an arrangement of 4, 6 or more combustion chambers the ratio of working cycles to running part revolutions is correspondingly improved! Altogether, lower manufacturing costs, lower maintenance costs, saving of fuel and improved environmental protection are to be achieved.

Patent DE-3514593-A1 (DE)
Title: Plug-in book spine for the plugging-in of part-works, stapled documents and grips as aid to the archiving of documents
Inventor: SCHELOWSKY MICHAEL
IPC: B42F9/00
Filed: 1985-04-23
Abstract: In their conventional form, literary works in the form of books have the characteristic that individual chapters and subject areas cannot be removed and reinserted, so that it is always necessary to handle the complete book. This is also a disadvantage for the book itself. Such removability is possible in the case of document binders, but is then linked to an office environment, with the disadvantage of the additional space requirement for the ring mechanism. The invention of the plug-in book spine avoids all these disadvantages and combines the advantages of the two forms, stapled subject sections or file sequences, as part-works, being plugged in to the clamp-type mounting of plastic grooves in the plug-in book spine and being removed therefrom in the same way. The visible strip of the plug-in book spine is, in the conventional and modern style of book design, to take the form of stickers. By means of additional gripping tabs which can be pushed into the end of the plug-in book spine, the archiving of plug-in books is facilitated as compared with the handling of conventional books in shelves, etc. A conversion to a plug-in book system would give office and administrative files, visually and conceptually, the character of a literary library as an alternative form of expedient modernisation.
