Patent DE-4119892-A1 (DE)
Inventor: STOERZEL KARL
IPC: F16D65/097
Filed: 1991-06-17
Abstract: In internally engaging floating caliper brakes, there is often only a very narrow axial space available for fitting and removing the brake pad (1). It is also highly desirable to secure the brake pad (1) to the piston (17) in order to ensure that the brake pad (1) is properly withdrawn at the end of the braking process. To this end, the invention proposes to provide simultaneously for the axial pretensioning of the brake pad (1) against the piston (17) and hence for the flexible securing of the pad to the piston by means of a spring leg (5) on the back-plate (2) of the brake pad (1) and a suitable guide path (11, 12) on the piston (17) through the radial inward movement of the brake pad (1). Advantageous further embodiments of the invention deal with measures to facilitate the removal of the brake pad (1) and the securing of the pad in the installed position against its undesirable rotary or axial movement in relation to the piston (17).
Patent DE-4120566-A1 (DE)
Inventor: SEIDEL WILLI
IPC: F16H61/10
Filed: 1991-06-21
Abstract: A process for controlling a preferably electro-hydraulically actuated gearbox of a motor vehicle provided with an internal combustion engine prevents upshifts or reduces the transmission ratio in and before curves. The upshift lock is initiated by quickly releasing the gas pedal during overrun. The upshift lock is suppressed as soon as a time interval after detection of the traction mode of operation has expired with no curve being turned. If an overrun mode of operation is again detected during said time interval, the upshift lock is maintained for a further time interval. After the upshift lock has been suppressed, the speed is gradually adapted to the standard given in the gearshift characteristic diagram.

Title: Semi-automatic liquid analysis - involves passing measurement liquid, air and cleaning and/or buffer soln. past biosensor in defined repeated sequence
Inventor: ASMANN FRANK DIPL ING
IPC: G01N1/00
Filed: 1992-08-18
Abstract: The method involves passing measurement liquid, air and cleaning and/or buffer soln. through a flow channel with a biosensor in a defined repeated sequence.
