Patent DE-3151029-A1 (DE)
Title: Expanding dowel
Inventor: GERHARD ANTON
IPC: F16B13/12
Filed: 1981-12-23
Abstract: An expanding dowel consists of an expanding sleeve (1) which is provided continuously with a slot (4) and has web-like flanges (7, 8) which bound the slot (4) laterally in the longitudinal direction and are bent away in the internal space (10) of said sleeve, and of an expanding pin (2) which can be driven into the internal space (10), abutting against the flanges (7, 8) and spreading the expanding sleeve (1). In order to make such an expanding dowel usable for insertion into hard masonry (29) and soft masonry (29'), the expanding pin (2) is provided with at least two undercuts (19) running in its longitudinal direction, for holding the longitudinal edges of the flanges (7, 8), and the distance between the longitudinal edges of the flanges (7, 8) when the expanding pin (2) is driven in is greater than when the expanding pin (2) is not driven in. <IMAGE>
Patent DE-3151757-A1 (DE)
Title: Method for testing an electromagnetic action device, particularly a relay with contact armatures encapsulated in an opaque housing, by representing and/or evaluating their armature movement and arrangement for carrying out the method
Inventor: BROCKEL BERTOLD DIPL PHYS
IPC: G01R31/327
Filed: 1981-12-29
Abstract: It is known that the change in inductance, which is produced by the armature movement when an electromagnetic action device is excited or deexcited, reacts on the exciter circuit (armature reaction). To test the relay characteristics, the signal component corresponding to this armature reaction is extracted and separately imaged and/or brought into relation with an excitation quantity independent of the armature movement. The said signal component provides information on the variation of the movement of the armature or of the armatures in the case of double-armature contacts with time. <IMAGE>

Title: Upper wind feeder
Inventor: NEULING HANS
IPC: F03D9/35
Filed: 1982-01-15
Abstract: Upper wind feeder designates a pipeline system which captures wind and feeds it to wind power machines which do not stand directly in the wind. It is characterised in that it captures the wind from great heights using funnels which are located in a pipe which is held automatically in the wind direction and can be swivelled by 360 DEG , and feeds it via pipelines to the wind power machine, which is set up near the ground or directly on the ground, and exhausts it and thus simultaneously utilises the compression and suction of the wind power.

Title: Method of operating a measuring device for determining the particle content of a medium by the filter principle and apparatus for performing the method
Inventor: KRACHLER WALTER ING
IPC: G01N1/22
Filed: 1982-01-21
Abstract: To reduce the consumption of filter material in the determination of the particle content of a medium by the filter principle, after the particles have been accumulated and subsequently measured, the filter material is freed of the sample residues in a regeneration unit and supplied for reuse in further sample collection. To simplify handling, the filter material may, for example, be a tape-type strip contained in a cassette unit. Furthermore, the cassette unit may contain the regeneration unit, which contains a chemical and/or ultrasonic cleaning bath. <IMAGE>

Title: Method and device for identifying paper rolls in a paper mill
Inventor: TIMONEN JUHANI
IPC: G06K19/06
Filed: 1982-02-08
Abstract: A method and a device for the reliable identification of paper rolls in a paper mill are described by means of which fully automatic marking of paper rolls at the longitudinal cutter or rewinder and automatic reading of the marking generated on the unpackaged roll is made possible. The customer rolls to be produced are provided with a bar code by applying ink or a similar marking substance to the edge of an unrolled paper web (W), in such a manner that at the end face of the roll (27) formed from the web (W), a bar code formed from concentric code rings (R1...R6) is produced which is later read. The device for carrying out the method exhibits a drive device (32) adapted to the blades (30) of a longitudinal cutter (11a, 11b), which device is connected via an arm (34) or the like to an ink pad (31) and which, due to the influence of a pulse coming from a computer system (33), presses an ink pad (33) or the like against the side of the blades (32) of the longitudinal cutter. <IMAGE>

Title: Method and device for sorting photographic originals into different subject groups
Inventor: FINDEIS GUENTER DIPL PHYS
IPC: G03B27/80
Filed: 1982-05-28
Abstract: Processes are known for sorting photographic originals into different subject groups which are to be copied using different density corrections which determine a deviation of quantity of copying light from a quantity of copying light which leads to an average grey density of the copy. This sorting is performed in accordance with photoelectrically determined density values of specific regions of the originals. In order to be able to carry out this sorting irrespective of the position of the original relative to the scanning direction, the measured values of the originals (1) are ordered in a co-ordinate system whose abscissa forms the relative blue density DB rel of the original, and the ordinate forms the relative maximum density DM rel of the central field (1a) of the same original. It is possible in this co-ordinate system to distinguish regions for originals which require strong positive, negative or only slight density corrections. <IMAGE>

Title: Process and apparatus for eliminating the danger of explosion in fibrous filter housings of rotary kiln drying ovens with fluidised bed firing
Inventor: HARTMANN HEINZ LEOPOLD DIPL IN
IPC: F26B25/00
Filed: 1982-09-01
Abstract: The aim is to eliminate the danger of explosion from over-rich oxygen occurring in the hot gases in the starting phase until the nominal load operation has been reached. This is achieved by spraying water into the hot gas stream during the starting phase, which lasts for several hours, after firing in the fluidised bed hot gas producer has begun, by regulating the quantity of sprayed water in dependence on the quantity of hot gas by means of conventional control units, and by using fibrous filters which are of oversize dimensions.

Title: Bearing for chain drive wheels of crawler tracks
Inventor: MOLLHAGEN PETER
IPC: F16H1/46
Filed: 1982-12-07
Abstract: The chain drive wheel of a crawler track is screwed onto a flange of a housing part which encloses the drive planet gear in a pot-like fashion. In order to keep the bearing for the drive chain wheel extremely short in the axial direction while making the design simple, the pot-like housing part (15) engages over a sheath-shaped part of the wheel axle pin (6', 10, 16). The pot-like housing part (15) is mounted on this sheath-shaped part in the region of a radial plane, which runs through the chain drive wheel (22), by means of a cross roller bearing (19) or a four point contact ball bearing.

Title: Working mixtures for sorption heat pumps, sorption refrigerators and sorption heat transformers
Inventor: STEPHAN KARL PROF DR ING
IPC: C09K5/04
Filed: 1982-12-16
Abstract: The patent application proposes various working mixtures consisting of the lower-boiling working material and the higher-boiling absorbent for use in sorption refrigerators, sorption heat pumps and sorption heat transformers. The mixtures known from refrigeration technology, of which ammonia/water and water/lithium bromide are used most frequently, can be used only with limitations in the heat pumps or heat transformers running at higher temperatures. Halogenated alcohols and, from this group of substances, especially trifluoroethanol are mentioned as a working material. These materials are above all distinguished by the moderate vapour pressures and the thermal stability at the temperatures which occur in the heat pumps. Suitable absorbents are organic solvents which are stable at high temperatures and have a boiling point above 260 DEG C. In detail, the following substances and groups of substances are proposed as absorbents for trifluoroethanol: glycol ethers, especially tetraethylene glycol dimethyl ether (E181), phthalates, sebacates, naphthols, naphthylamine, tetraethylenepentamine, diphenylamine, benzophenone and 2-hydroxybiphenyl. The temperature ranges, within which sorption processes with the said working mixtures can be operated, are also indicated.
