Patent DE-4000026-A1 (DE)
Title: Electronic multiplier circuit - contains control stage with six counters and short shift register or seven counters bit no long shift register
Inventor: MERKLE PAUL
IPC: G06F7/491
Filed: 1990-01-02
Abstract: The electronic multiplier circuit does not have a long shift register as the main part of its control arrangement. It contains six counters (62-67) and a short shift register (61) or seven counters. None of the counters exceeds the range 0 to 10.

Title: Altering bit error rate - inputs errors or changing connections to prevent system abuse
Inventor: DYCZMONS WOLFGANG DIPL ING
IPC: H04L12/14
Filed: 1990-01-15
Abstract: In an ISDN exchange, conference sets are so switched at a set frequency as to add in error bits from a  generator to data convections improperly applied as telephone connections. The result is to raise the  error rate. Alternatively, part line bundles are switched with raised error rates so as to massively distort the abusing connections. As a third possibility, bundle loops, i.e. line bundles looping back to the same exchange point, are switched to distort the connections. ADVANTAGE - Prevents use of speech connections by data transmissions which ought to attract higher line tariff.

Title: Tyre for high performance cars
Inventor: TOKUTAKE MASAYUKI
IPC: B60C13/00
Filed: 1990-01-31
Abstract: A tyre has a cylinder-shaped crown and sidewall from the shoulder to the radially inner bead with its embedded ring. It has a carcass in which each radially inner end is bent outwards round a bead ring and extends high up on the radially outer end of the tyre; it has a belt of at least two layers at the crown and a tread on top; a hard rubber infill is between the carcass layer and the high wrapped part so as to form a cone from the bead ring to the crown; and the tyre has at least one oblique cord layer which is overlapped by the hard rubber infill. The radially outer end of the wrapped carcass, the rubber infill, and the oblique cord all extend to about the centre of the sidewall so as to strengthen the radially inner part of the sidewall; the resultant position of max. width of carcass is at least 60% of the height of the tyre cross-section (before inflating the tyre) outwards from the foot of the bead; this position however is shifted when the tyre is inflated. The axial distance between the feet of the two beads is less before inflating than afterwards; the lateral guide of the tyre or the vehicle performance can thus be increased as a high tension is produced in the sidewall when the tyre is inflated, and the transverse stiffness and the area of contact with the ground are increased.

Inventor: HECKL FRANZ
IPC: B01D25/21
Filed: 1991-06-11
Abstract: The filter element consists of several filter plates held against a supporting face, within a surrounding frame, jointly forming a chamber with inlets for the fluid to be filtered retained by a rubber membrane. The membrane face facing the filter chamber bears a profiled projection which supports the filter gauze, jointly creating a cavity which supplies the filtrate outlet. The rubber membrane has a rim by virtue of which it can be closed with or removed from the filter plate; the rim interlocks with the outer face of the filter plate; the rim and matching groove are roughly rectangular; the rim height is a little greater than the height of the groove in the filter plate; and the inwardly facing rim corners bear lips which deform elastically to fit into the filter groove to form a roughly V-shaped cavity. USE/ADVANTAGE - The V-shaped rubber rim creates an effective seal between membrane and filter plate and simplifies assembly.
