Patent DE-2902718-A1 (DE)
Title: Electric short circuit protection for vehicle involved in collision - is esp. for hazardous loads, and uses accelerometer to introduce cut=out with low trip setting
Inventor: STANGL MANFRED
IPC: B60K28/14
Filed: 1979-01-25
Abstract: German traffic regulations prescribe an isolator switch in the driver's cabin which can be used to cut off all electrical circuits in a truck carrying hazardous goods. This switch, is, however, useless if, in case of accidents, a short-circuit is caused before the driver has a chance to operate the switch. This risk can be obviated by connecting the truck chassis (1) to the negative pole (2) of the battery via the contacts (3) of a contactor (4). The coil (5) of the latter is energised by the ignition key G via the N.C. contact (6) of a relay (7). If a collision actuates an acceleration switch (11), the coil (12) is energised, the switch (11) is shunted, and the contactor (4) drops out, to interpose the miniature cut-out in circuit and this allows just enough current to pass to energise the parking lights, but cuts out immediately if the collision has caused a short circuit.

Title: Retroreflective strip on tyre side wall - esp. for bicycles, has profiled form to give high reflectivity
Inventor: KERN WALTER
IPC: B60C13/00
Filed: 1980-10-16
Abstract: A pneumatic tyre, esp. for bicycles, has one or more integrally vulcanised, retroreflective strips composed of a transparent layer with glass spherical or hemispherical beads embedded in it, and a light-reflective surface. The retroreflective strips (10) are profiled (14), esp. by embossing or knurling. Pref. the strips are on both side walls of the tyre. The profiling may be produced simultaneously with the vulcanising of the tyre side wall. In particular where the angle of incidence of the oncoming vehicle headlight to the plance of the wheel is comparatively acute, the use of a profile form (14), ensures that there will be adequate reflection from the light source (Q) back to the observer (A) due to the undulations of the strip. The strip can thus be located in a portion of the side wall not subjected to heavy stresses in use or in vulcanisation which can damage the strip.
