Abstract: Wiping and washing systems, in particular for motor vehicle windshields, having an oscillating windshield wiper that can be driven back and forth over the windshield and first and second washing nozzles that can be moved with the windshield wiper and that are oriented towards different sides of the windshield wiper, are known. The first washing nozzle can be supplied with washing fluid during a first part of the windshield wiper movement and the second washing nozzle can be supplied with washing fluid during a second part of the windshield wiper movement. The problem remains of supplying the washing nozzles with washing fluid by simple means. According to a first solution to this problem, the first washing nozzle is linked to a first washing pump and the second washing nozzle is linked to a second washing pump. The first washing pump can be switched on during the first part of the windshield wiper movement and the second washing pump can be switched on during the second part of the windshield wiper movement. According to a second solution, a washing pump with reversible directions of rotation has a suction line with a first delivery line for supplying the first washing nozzle with washing fluid when the pump turns in one direction and with a second delivery line for supplying the second washing nozzle with washing fluid when the pump turns in the other direction.

Patent DE-4132197-A1 (DE)
Inventor: HAGENAUER FRANZ
IPC: F27B9/26
Filed: 1991-09-27
Abstract: In a process for the thermic treatment of workpieces, the workpieces are moved on grates (24) through at least one furnace chamber (26) of a furnace (10). For advance, the grates (24) are raised from the furnace floor during a lifting phase, then in the raised state moved translationally in the direction of transport, preferably via a pusher (28), and finally set down again on the furnace floor in a lowering phase. As a result of the translational movement in the raised state of the grates, frictional forces are avoided and operational safety is increased. A furnace for implementing the process has at least two slides arranged one above the other under the grates (24), the upper slide being raisable in relation to the lower slide, in order to lift the grates (24) from the furnace floor, and both slides being displaceable together in the raised position for transport of the grates (24). Both slides preferably have inclined planes lying on one another in order to make possible raising or lowering of the upper slide. <IMAGE>
