Title: Load-dependent braking force adjuster with electromagnetic control - adapts closing pressure to vehicular load by variation of travel of pistons into contact with spring
Inventor: CEZANNE RUDOLF DIPL ING
IPC: B60T8/26
Filed: 1991-08-03
Abstract: Two identical units are mounted one behind the other with their stepped pistons (4) actuated by a common balance beam (15) rocking about a control plunger (16) fixed to a hollow cylinder (17), which protrudes into a sleeve (19) surrounding the electromagnet plunger (29). Under lighter loading the coil (31) carries more current, retracting the armature (30) so that ball-bearings (28) can move inwards and the pistons (4) travel further to make contact with the adjustment spring (24) when the brake fluid pressure is built up.

Patent DE-4214493-A1 (DE)
Inventor: GRUNDKE REINHOLD
IPC: A61M5/32
Filed: 1992-05-07
Abstract: A protective sheath for the disposal of a used disposable hollow needle (9) is improved with respect to known protective sheaths of the same type which avoid the danger of pricking when the user disposes of the used hollow needle (9), so that the danger of squirting is also avoided during disposal of the hollow needle (9). For that purpose, a squirt guarding wall (3a, 3b, 6, 7) is located over the end area of the elastically closed lateral passage through which the used hollow needle (9) can be pushed from the side into a reception chamber (11b) in the protective sheaths of the same type. The squirt guarding wall (3a, 3b, 6, 7) defines over this end area an insertion chamber (11a) which is only open at one front side and closed on all other sides. The hollow needle (9) to be disposed of must be inserted into this chamber (11a) over an end area adjacent to its needle point (9b) before it is pressed into the reception chamber (11) through the passage, so that possibly highly infectious liquids which may hang from the needle point are prevented from squirting into the environment when the needle (9b) is pressed through the passage.
