Title: Method and circuit arrangement for converting analog scanning signals into binary squarewave signals
Inventor: KUREK HEINZ
IPC: G06T1/00
Filed: 1982-02-03
Abstract: Analog scanning signals (A) which are generated during the opto-electrical scanning of a document (V), are converted into binary squarewave signals (12) by the analog scanning signals (A) being compared with at least one threshold value (SW) and the squarewave signals (12) being generated when the analog signals exceed or drop below the threshold value (SW). The threshold value (SW) can be changed in dependence on the scanning signals (A) and is generated by an arithmetic averaging of the instantaneous values of the scanning signals (A). The scanning signals (A) are delayed due to the time required for the averaging and are compared only then with the respective threshold value (SW). The time by which the scanning signals (A) are delayed is dimensioned in such a manner that scanning signals (A) with high frequencies are optimally weighted. When scanning signals (A) are lacking, the threshold value (SW) corresponds to an adjustable basic value (G). In addition, a sensor can be provided which changes the threshold value (SW) in dependence on the intensity of illumination of a lamp illuminating the document (V). <IMAGE>

Patent DE-3211437-A1 (DE)
Title: Mechanical transmission
Inventor: BEUKE KARL
IPC: F16H21/14
Filed: 1982-03-27
Abstract: There are transmissions with a transmission shaft which is connected to a piston machine and is arranged offset relative to the axis of a further transmission shaft. Attached to one of the transmission shafts in torsionally rigid fashion is a driver which, to compensate the misalignment engages with a slider in a radial guide track of a slideway body seated firmly on the other transmission shaft. In order to ensure with such a transmission that less fuel is consumed, the combustion process in the case of a piston engine operating as an internal combustion engine takes place during that part of the revolution of the transmission shafts during which the slider or a connection part of one transmission shaft reaches a maximum radial distance from the axis of rotation of the other transmission shaft. In order to be able to better utilise available driving energy, the compression stroke in the case of a piston machine operating as a compressor or the like takes place during that part of the revolution of the transmission shafts during which the slider or a connection part of one transmission shaft reaches its minimum radial distance from the axis of rotation of the other transmission shaft. In both cases, the radial slideway is in each case single-track as known per se.

Patent DE-3219575-A1 (DE)
Title: Implant system for correction of the position and stabilisation of the spine
Inventor: KLUGER PATRICK DR MED
IPC: A61B17/70
Filed: 1982-05-25
Abstract: For the operative correction of instabilities and incorrect positions of the spine with a wide variety of causes there is a need for implants which can be used to correct an incorrect spinal position and to achieve reliable stabilisation with the aim of achieving early load-bearing capacity. Such implants must fulfil two principles: they require very stable anchorage in the vertebrae above and below the instability or the incorrect position as well as a longitudinal support system which must be adapted to suit the distances between the anchorage points and the incorrect position of the spine. If the angle between the anchorage part in the spine and the longitudinal support system is kept stable, assembly can be restricted to only one vertebral segment above and below the instability. The invention relates to an implant system which is anchored with bone screws in the arch roots of vertebrae above and below the spinal instability. The longitudinal support system is in each case formed by two threaded rods which are connected with a hollow rod with contrary internal screw threads, length and rotational position being infinitely adjustable. Angular stability between the longitudinal support system and the anchorage screw is guaranteed by corner pieces which carry a grid disc for the purpose of connection. The bone screws used for anchorage project beyond the rear surface of the spine to such an extent that the position of the spine can be corrected with the long levers, which position is then fixed by fastening the corner pieces with the longitudinal supports. The projecting screw ends are then shortened. The dimensions of the total implant system are such that wound closure is possible above it.

Filed: 1982-08-09
Abstract: A reinforced concrete building element for planar slatted floors having a downwardly tapering cross-section is used, when joining together a plurality of elements, to construct a slatted floor having a plurality of downwardly widening liquid manure gaps (2). The building element (1) can have the shape of beams or grates and is provided, immediately below the standing surface (13), with lateral dung break-off edges (12) to avoid deposits of dung. For effectively preventing the wetting of the side faces (3) of the building element (1), in particular in the lower zone subjected to tension, with liquid manure as a result of the latter flowing down on the side faces and hence decompositions as a result of the liquid penetrating into the hairline cracks arising there, the building element has an undercut drip edge (5) along the side faces (3) in the vicinity of the neutral fibre (40). The liquid drips off this drip edge (5) under the effect of gravity. <IMAGE>

Patent DE-3243577-A1 (DE)
Title: Small pouch
Inventor: KRAUSE EBERHARD
IPC: A45C13/10
Filed: 1982-11-25
Abstract: A small pouch, for example a purse, a key wallet, a cosmetics pouch or the like, has side parts which are made of flexible material, such as leather or plastic, are situated opposite one another and can be pivoted with respect to one another in order to open and close the pouch. Arranged opposite one another in the vicinity of the opening edge (16) of the two side walls (10) are two flexible magnetic strips, which extend over the width of the side wall and whose surface parts facing one another have oppositely polarised magnetisation in order to form a holding closure. The magnetic strips (18) project over the inner surface of the side walls (10), and thereby form a limit stop for the pouch contents. On tipping out the pouch contents, any magnetisable objects (26') adhere to one of the magnetic strips (18). Since the lining (36) of the small pouch itself, or a foil (38) arranged inside the lining, consists of magnetic material, magnetisable and non-magnetisable parts are automatically sorted out in the pouch. In this way, the magnetisable small coins (26') are separated, for example in purses or waiters' serving pouches, from the non-magnetisable larger coins (26) and can thus more easily be sorted and removed. <IMAGE>
Patent DE-3302688-A1 (DE)
Title: Clip-type drawing pins
Inventor: STRAHL GERHARD
IPC: B43M15/00
Filed: 1983-01-27
Abstract: Commercially available drawing pins are pressed into the material to be fastened, thereby damaging the material. In addition, when removing the commercially available drawing pins it is easy for injuries to fingers to occur, or even the fingernail to be torn, especially as these drawing pins can only be detached with difficulty from the fastening surface. A steel or hard-metal spike, of about 1mm . 10mm in length and diameter, is pressed into the smaller metal platelet of a double metal platelet bent off in the form of a U and of a size of about 1mm . 10mm . 20mm. An air gap may or may not remain between the metal platelets. These novel clip-type drawing pins have several advantages. The material to be fastened is not damaged. The clip-type drawing pins can remain in the fastening surface and be used for further fastening operations by resiliently bending up the upper plate and pushing the new item of material under the resilient clip catch. Removing the clip-type drawing pins is also easier and safer to carry out than in the case of conventional drawing pins. The upper plate of the clip-type drawing pins is bent up by a fingernail without any risk of injury, producing a sufficiently large gripping area by which the clip-type drawing pins can be easily pulled out.

Title: Method for regenerating and inerting the absorber units, the molecular sieve and further appliances in an installation for the dry recovery of solvents, and installation for implementing said method
Inventor: SCHEUCHL RICHARD
IPC: B01D53/04
Filed: 1983-02-02
Abstract: In order to achieve rapid and safe regeneration and inerting of the adsorber units, the molecule sieve and further appliances forming part of an installation for the dry recovery of solvents from a gas stream, at the start of the initiation of regeneration a reduced pressure is generated by evacuation, and said reduced pressure is then cancelled out by adding an inert gas into the system. By repeating this process several times, rapid and extensive inerting of the installation is achieved. Finally, in order to regenerate the molecular sieve the heated gas stream used for this purpose after passing through the molecular sieve is discharged into the atmosphere, so as to preclude entirely the reentry of humidity into the installation. The regeneration of the molecular sieve, according to the invention, uses heated air as the heated gas stream. <IMAGE>
