Patent DE-4304367-A1 (DE)
Inventor: SPITZL WALTER
IPC: H01H19/60
Filed: 1993-02-13
Abstract: A switching apparatus, eg for a cooker hot plate, comprises a rotary switch which is closed by rotating a switching shaft 6 in one main direction from a zero position and an auxiliary switch having an unidirectionally rotatable star wheel 9 which is rotatable by a protuberance 8 on a resilient disc 7 on the switching shaft 6. Upon actuation of the rotary switch in its main direction of rotation from the zero position the star wheel 9 is not rotated. Upon rotation of the switching shaft 6 of the rotary switch in the opposite direction from the zero position the star wheel 9 is moved to close a spring contact 11 of the auxiliary switch. The auxiliary switch remains closed upon subsequent rotation of the switching shaft 6 in the main direction of rotation. Only upon return of the rotary switch into the zero position is the switching contact 11 opened again. <IMAGE>

Title: Method for the conveyance of powder-like material stored in flexible containers
Inventor: PINGEL JOACHIM
IPC: B05B7/14
Filed: 1993-05-01
Abstract: In order, in the conveyance of powder-like material stored in flexible containers, to guarantee a uniform follow-up of the material to the suction point according to the progress of the emptying operation and to allow a simplified monitoring of the filling level, at least part of the container wall follows up towards a suction device in dependence on the filling level of the material and, with an increasing emptying of the material, is subjected to a necessary minimum lateral pressure, at least in the effective draw-in region of the suction device. Consequently, as a result of the mechanical effect of the flexible wall of the container, the material follows up into the region of the suction pipe. <IMAGE>

Title: Rolling mill with means for roll changing
Inventor: BUJOK CRISPIN
IPC: B21B31/10
Filed: 1993-06-30
Abstract: In rolling mills whose lower work roll is at the level of the mill floor, it has hitherto been necessary to free the changing pit provided for changing the back-up rolls from the cover plates which cover it. This was generally accomplished by using cranes to lift off the plates. In order to make this time-consuming removal of the cover plates more efficient, the proposal is to provide the cover plates in the form of pivotable plates and to arrange them between the respective stands and the transversely displaceable support plates bringing about a lateral displacement of the work roll sets.

Patent DE-4336107-A1 (DE)
Title: Pane/window-raiser connecting unit for a double-glass pane
Inventor: HEUBERGER JUERGEN
IPC: E05F11/38
Filed: 1993-10-22
Abstract: Known pane/window-raiser connecting units for single-glass panes, such as are used for lowerable motor-vehicle windows, often additionally subject the pane, during the raising movement, to a transverse force which provides a pivoting moment for pressing the pane against a vehicle-door seal. The new pane/window-raiser connecting unit is suitable for a double-glass pane (1) consisting of two individual glass panes (2, 3) adhesively bonded to one another with a spacing by means of a strand of sealing adhesive inserted in between along the edge and contains at least one pane holder (4) couplable to a window raiser and having two spaced guide walls (11, 12), between which an edge region of the pane is received and to which the pane is fixed, and having a small pressure plate (6) which is assigned to each pane holder and which is arranged between the two individual glass panes in the region of the guide walls and at a distance from the strand of sealing adhesive. The small pressure plate arranged between the individual glass panes makes it possible, together with the stand of sealing adhesive along the edge, without the risk of breakage to transmit transverse forces for pressing the pane against a sealing profile. The invention is used, for example, for lowerable panes in vehicle doors without a window frame. <IMAGE>
Patent DE-4408752-A1 (DE)
Title: Pressure regulating setting device
Inventor: TSUKAMOTO MASAHIRO
IPC: B60T8/48
Filed: 1994-03-15
Abstract: A pressure regulating setting device suitable for a motor vehicle brake control system includes a pressure setting cylinder which surrounds a piston in a sliding manner and interacts with the piston, in order to define within itself a pressure chamber of variable volume which is fluidically connected to a wheel brake cylinder, a shut-off valve via which the chamber of variable volume is connected to a main brake cylinder, a motor-driven thrust generator which is connected to the piston in a non-positive manner in order to generate a thrust, and a strongly pre-loaded reset spring which prestresses the piston into a first direction, which is opposed to a second direction into which the piston is thrust by the main brake cylinder pressure enclosed in the chamber, when the piston is displaced from its neutral position into the second direction and thus the volume of the chamber is increased. The preloading of the spring is set in such a way that by means of a force which acts on the piston through a maximum main brake cylinder pressure introduced into the cylinder, an equivalence is produced. In the absence of a thrust acting on the piston after terminating an ABS control, for reducing the pressure, the piston returns rapidly and exactly into its neutral position. A zero thrust ensures a rapid resetting of the piston into the neutral position by means of a slight brake actuation after completing a traction control action for increasing the pressure.
