Patent DE-3701574-A1 (DE)
Title: Screw head with slot
Inventor: WITTMANN HELMUT R W
IPC: F16B1/00
Filed: 1987-01-21
Abstract: Forms of screw heads with slots, securing and safety screws with turning-tool tips. Forms of screw heads from any bodies of rotation (3) obtained by a peripheral/diametrical (1) or a peripheral/radial (2) slot arrangement distributed at variable radial angles; the special configurations of the slot base surfaces (12, 13) and the plane-parallel slot flanks (4) or wedge flanks (5), improved properties in various types of screws:   optimum torque transmission, self-centring and large angle range of the tool tips (10, 11), a low degree of machining and re-shaping work during production, coding of features on the screw head, series-produced centring bore (8) or means (9) of protection against drilling.   The modification of the slot flanks (15, 16) provides special types and non-releasable securing screws. By virtue of computer-controlled shear-surfaces, securing screws with a predetermined tightening moment can be produced. Radial slot arrangements give rise to safety screws, which can be screwed in and unscrewed, for high degrees of safety requirements. The subdivision of the head periphery into zones and sectors and the graduation of the slot depths permits, by virtue of an additional profiling of the slot bases, the production of very complex safety screws. In the case of all screw types, the optimum strength of the bolt system is always ensured by the minimal core head (rivet head). <IMAGE>

Title: Mould for concrete grid and method for the production of a concrete grid
Inventor: ULLSTEIN JUN HANNS
IPC: E01C9/00
Filed: 1987-03-27
Abstract: Grids of concrete are employed in particular as so-called grass slabs, which are grid-type slabs, the interspaces of which are filled up with earth in order to sow grass there. The area, which is partly covered by the grass, is visually attractive but at the same time prevents destruction of the grass by heavy mechanical loading, for example by car tyres or the like. The invention provides an assemblable mould made of cardboard for producing concrete grids of this type. Thin cardboard strips are fitted together to form a uniform pattern, in which squares arranged in rows and columns are surrounded by respectively adjacent, interconnected channels. The squares are filled with gravel, sand or earth, and subsequently the channels are filled with concrete. As a result, the concrete grids can be produced in situ. They may also be lifted up in order to be re-laid at another location.

Title: Elastic shaft/hub connection secure against twisting
Inventor: BOLL WOLF DR ING
IPC: F16D3/76
Filed: 1988-07-05
Abstract: In order to obtain a lightweight shaft/hub connection which allows relative displacement under axial force, is secure against twisting and is slightly elastic, the shaft or hub of a splined connection is coated in the region of the connection with a flexible layer, to which in turn a metallic covering is applied. The hub or the shaft as the basic elements, on the one hand, and the metallic covering, on the other hand, are each connected permanently to the flexible layer.   A splined connection of this kind is easy to assemble despite the elasticity imparted to it by the flexible layer, since only metal surfaces have to be brought into contact with one another. The flexible interlayer in the shaft/hub connection effects decoupling of vibration and noise and permits relatively small angular misalignments between the shaft and the hub.
Patent DE-3833723-A1 (DE)
Inventor: BERG PETER VON
IPC: A61B5/03
Filed: 1988-10-04
Abstract: In a pressure meter catheter which carries a pressure sensor in its measuring tip a reference pressure is admitted to effect zero setting in accordance with the invention while the instrument is in situ during a measurement, the reference pressure permitting adjustment of an evaluating unit at a remote location. Preferably, the measuring tip is surrounded in sealing fashion by a balloon which can be inflated through the line in the catheter tube through which atmospheric pressure is applied to the sensor as reference pressure for the measurement. Thus the same pressure is available both at the measuring connection and at the reference connection of the sensor, and the pressure differential measured by the sensor consequently is exactly zero.
