Title: Clamping device for data carriers
Inventor: LUHDE RAINER
IPC: G11B23/00
Filed: 1993-10-06
Abstract: The patent application of 20.09.1993 relates to a clamping device based on a force-locking principle. A data-carrier CD is clamped in a force-locking manner.

Title: Injection mould
Inventor: TAKAHASHI MITSUO
IPC: B29L17/00
Filed: 1994-03-23
Abstract: The injection mould serves for the injection moulding of base plates for use as an information storage medium, for instance as a photoelectromagnetic plate or the like.

Title: Scanning device for measuring depth, position and number of steel reinforcing bars in concrete
Inventor: SEITZ HOLGER F K DIPL ING
IPC: G01V3/08
Filed: 1994-04-28
Abstract: The scanning device involves measuring probes working on a magnetic or inductive principle, which take a number of readings i.e. at least 5, along a concrete surface. The measured data signals together with the corresponding surface positions are simultaneously processed and shown as a graph e.g. on a liquid crystal display of a portable battery-operated unit.The probe responds to a bar by indicating a maximum peak on the graph as it moves across the surface, and indicates e.g. 2 peaks if there are 2 bars close together, where a lower maximum also suggests a more deeply situated bar. Thus position measurement of the bars relative to the surface and each other is enabled.

Title: Rail tunnel arranged as three=tube system
Inventor: HANKINS JOHN
IPC: E21D9/14
Filed: 1994-09-16
Abstract: The three tunnel tubes (15,24) can be travelled in either direction and are interconnected at specified intervals by cross links (16,26) to permit partial traffic exchange between the tubes. The three tubes are spatially offset from one another, giving direct cross links (26) between the tunnel tubes,using watertight gates (22,23) to lock off the respective cross links as required. A typical stretch of tunnel runs between two stations and allows three-railtrack traffic (14) in respective tubes (15), using the cross links to redirect traffic into any one of the tubes as required, assisted by linked points (18). Narrow section galleries between the tubes provide an escape route or hold supplies during repair etc. work, and accommodate the watertight gates (22,23) to close off tubes against flooding etc.

Title: Process for forming a theoretical value of an adjusting, respectively control device for a heating installation
Inventor: STUCH DIETER
IPC: F24D19/10
Filed: 1983-07-30
Abstract: Process for providing a theoretical value of an adjusting, respectively control device for the outgoing temperature of a heating installation as a function of the outside temperature. Such theoretical values are normally provided to the regulator in the form of heating curves. The heating curves are non-linear relationships and it is difficult for a regulator to process them as such. Owing to this invention the curve is fractionated into two straight lines of different slopes which meet at a common point. Said point is situated where the relationship between the heating curve and the linear relationship reaches a maximum with respect to the outer temperature.
