Patent DE-3813352-A1 (DE)
Title: Vertical sizing bandsaw
Inventor: BOBAN FRANZ
IPC: B27B27/10
Filed: 1988-04-21
Abstract: The previous generation of vertical bandsaws only permits cuts of limited length which are defined by the diameter of the saw-band wheel and by the machine carrier. Also inadequate is the quality of the longitudinal and mitre cuts on these highly sensitive machines, since only insufficient attachments are provided. If the saw band is now turned by 90 degrees, the cutting-to-size of any length is possible, and in fact on both sides of the saw band. But the effectiveness of the bandsaw machines is also substantially increased if an exact parallel guide is attached which is equipped with both a mitring attachment and an adjustable length stop. This makes possible high-precision length and mitre cuts which meet all requirements of a vertical sizing bandsaw.
Patent DE-3816638-A1 (DE)
Title: Coupling device
Inventor: HADER HELMUT
IPC: A61C8/00
Filed: 1988-05-16
Abstract: The coupling device comprises an intermediate piece (7) which is made up of a helically wound wire and is screwed onto a thread (4) at the end of a plug-in part (3). Said intermediate piece is introduced, with a pronounced degree of friction, into a bore (2) of a socket part (1). A rotation of the plug-in part (3) in said intermediate piece (7) results in locking of the parts (1) and (3) which are to be coupled. <IMAGE>
Patent DE-3820626-A1 (DE)
Title: Marking apparatus
Inventor: TENZLER THOMAS
IPC: B42D9/00
Filed: 1988-06-20
Abstract: In an earlier marking apparatus for a printed publication, a carrier strip forms an open loop at each of its two free ends, by means of which it is held on the printed publication by frictional fitting. In an earlier bookmark, at least two superposed tabs of any desired design are provided, connected to each other via a spine. The two known articles are labour-intensive to produce, require special tools and are consequently very expensive. The new apparatus is to be more economical to produce with at least equal frictional fitting. A blank of flexible sheet-like material with at least two resilient tongues, capable of being bent as desired relative to one another, is provided, the tongues being separated from each other by a cut or a gap existing between them. A linear stop edge at one or both ends of the gap facilitate the use of the blank as a reading rule. The new apparatus can be produced very economically, frictional fitting being achievable which is comparable with what has hitherto been achievable. A special tool for bending and assembly work is unnecessary, so that production is primarily only capital-intensive. <IMAGE>

Title: Magnetic field sensor
Inventor: RIEWE FRANZ-JUERGEN
IPC: G01R33/02
Filed: 1988-07-16
Abstract: In a magnetic field sensor for slowly changing magnetic fields, two coils (1, 2) of opposite polarity are provided in the field and are connected periodically for short, predetermined time intervals to a current source. Rectifier circuits (11, 13; 12, 14) connected downstream of the two coils deliver two saw-tooth voltages following the change in the magnetic field, the said voltages being freed in a subsequent amplifier circuit (15, 16) from the ripple brought about by the periodical switching of the coils (Fig. 1). <IMAGE>

Title: Drilling device for making drilled holes with undercut
Inventor: HAAGE MANFRED
IPC: B23B51/00
Filed: 1988-12-08
Abstract: Drilling devices for making undercut drilled holes are known, in the case of which during the drilling operation, the drilling shank is centred by means of small drilling plates present on the drilling shank. In this arrangement, the drilling shank is mounted with play in order to enable swinging-out. This has the result that the drill can yield laterally during the drilling operation, thereby producing curved drilled holes. In order to improve the centring during the drilling operation, a drilling device is proposed, on the drilling shank of which there is located a centring ring, by means of which the drilling shank is locked, during the drilling operation, to the centring tube through which it runs.

Inventor: HARTNACK WOLFGANG DIPL ING
IPC: H04N19/527
Filed: 1989-03-03
Abstract: An electronic image-reproducing device for digital video signals comprises a block-limit light-diffusing screen for reducing the visibility of block limits in video signals. In the case of calculation specifications which differ from block to block for the image points in video signal blocks, the block limits can be irritatingly visible during the reproduction of given image contents. The light-diffusing screen for block limits constitutes a smooth transition for the image points on said block limits between the different modes of calculation. Application to digital image signal processing.
