IPC: F41A21/12
Filed: 1991-03-15
Abstract: In order to provide a 6.5 calibre cartridge for rifles, the case of which is suitable for both light and heavy projectiles without adversely affecting accuracy, thus producing an increase in the efficiency of the propellant charge, a reduction in the stress on the barrel and breech of the weapon and the production of shorter  and hence lighter weapons and an increase in the useful life of the reloadable case, a cartridge has been developed distinguished by reduced length of the virtually cylindrical region (117) of the case (11) between the base (111) and the transition (113) to the neck (114) of the case and an extremely flat transition (113) in the neck (114), and in connection therewith a suitable cartridge chamber has also been developed.

Title: Information transmission via two binary transmission channels - using simultaneous transmission of data signal and inverted data signal and combining by logical disjunction
Inventor: CLAUSS ULRICH DR
IPC: H04L25/40
Filed: 1991-03-30
Abstract: The data pulse sequence and its negative version are each combined with a clock pulse sequence at the transmission end, e.g. via an AND gate (6,7), and transmitted via 2 independent transmission channels (1,2). The pulses are shortened at the reception end and a time variant clock signal is obtained by disjunctive combining of the 2 signals, for restoration of the data signal obtained from one signal path. A transmission fault signal is supplied upon detection of a transmission fault after combining the 2 transmittted signals. ADVANTAGE - Improved tolerance for signal delays.

Title: False twister yarn path - has surface structures to allow twist to travel back along the yarn
Inventor: SCHIPPERS HEINZ DR ING
IPC: D02G1/02
Filed: 1992-08-17
Abstract: In the false twisting assembly, where the yarn travels along a curved cooling rail path over the walkway between the creel and the false twister, the yarn path is structured at least at the strongly curved section by regular path surfaces (22, 27) across the direction (21) of yarn travel, at regular intervals. The structure of the yarn path is formed by depressions (27) and raised webs (22), at an angle to the line (21) of yarn travel, pitched agains the direction of twist in the yarn or in the twist direction. The angle formed by the surface structure (22, 27) to the line (21) of travel is 90-45 deg. and pref. 80-55 deg. and is pref. greater than the angle formed by the twisted yarn yarn filaments to the line of travel. The difference in height between the base of the depressions (27) and the peaks of the projections (22) is at least 100 microns and pref. at least 200 microns, or 300-1200 microns and pref. 400-1000 microns. The path structures (22, 27) are in mirror image symmetry on both sides of the yarn line (21) of travel. The structures (22, 27) can be arranged to form an arrowhead, with the point on the line of travel and pointing along the direction (21) of yarn movement, or against the direction (21). The yarn path can also be structured by alternating projections from the sides, at least in contact at their gaps, at right angles to the yarn travel, to cover the facing sides between projections by at least 300 microns and pref. 400-1500 microns. ADVANTAGE - The structured pathway allows the twist in the yarn to travel back along the yarn from the false twister as far as possible.

Title: Servo steering for motor vehicle - with working pressure differential which attempts to move control piston in direction to lower differential
Inventor: WEILER WERNER DIPL ING
IPC: F15B13/04

The other working pressure (P2) charges a smaller active surface (A2) on the piston in the opposite direction (1). The regulating pressure charges another active surface (AR) in the second direction. ADVANTAGE  - Simple construction. Improved.
