Title: Vehicle window breaker - has paired toothed rollers followed by removal of glass fragments from both sides of film between the glass panes
Inventor: SALZMANN OTTOMAR
IPC: B02C4/08
Filed: 1992-01-14
Abstract: Appts. to break up bonded glass windows, in a vehicle breaking operation, has at least two parallel toothed rollers (2,3) with teeth (4) round their circumference. A system rotates and presses at least one of the toothed rollers (2,3) in the direction of the bonded glass (2) pane movement. After the rollers (2,3), the clinging glass particles (18) are removed from both sides of the bonding film which was between the glass panes, and the detached glass fragments (18) are deposited in a container. Rotating brushes, after the toothed rollers (2,3), detach the glass fragments (18) from both sides of the film. The teeth (4) of the toothed rollers (2,3) have a truncated cone profile, with cambered flanks and are displaced from each other in axial sections round the rotary angle by half a tooth interval, or the tooth profile gives an aligned profile flow over the whole axial roller length. At least one of the toothed rollers (2,3) is moved to and fro axially, at intervals, and at least one roller (2,3) is spring loaded in the direction of the other roller. At least one of the toothed rollers (2,3) is subjected to a low amplitude vibration, with a max. of a few mm, at a frequency of at least 10 Hz. The first pair of toothed rollers (2,3) have a toothed profile which has a tooth height at least twice the thickness of the bonded window (1). and pref. four to give times the window (1) thickness. A second pair of toothed rollers can be positioned after the first pair (2,3), with the dia. and toothed profile shape smaller than the structure of the first rollers (2,3) by a factor of 2-5. The assembly and/or brushes to detach the glass fragments (18) from the intermediate film do not lie straight across the window (1), but are at an angle of less than 180 deg. to each other so that the film follows a roof-shaped path between them. At least two ring grooves, at least in each lower toothed roller (3), are distributed over the axial length for running webs to be inserted at the level of the base of the teeth from the outlet side of the roller, to support the moving film between the glass levels in the window (1). ADVANTAGE - The action gives a positive separation of the glass panes from the bonding film, without a risk to the operatives in disposing of vehicle windows.

Filed: 1992-02-03
Abstract: In order to drive converters (4, 6) which are connected on the primary side (I) and on the secondary side (II) of an inductive element (2) which is provided for power transmission to said element (2) and are switched at a constant duty ratio, the converters (4) on the primary side (1) are driven from a central switching signal source at a constant frequency while, in contrast, the converters (6) on the secondary side (2) are supplied with control signals which are derived from the voltage behaviour on the inductive element. As a result of this method, it is possible to design the drive of the converters (4, 6) in such a manner that they are switched as a function of one another without being directly connected to one another. <IMAGE>

Title: Fluid controlled feed pump - has pump chamber with vol. enlarged on suction stroke and reduced on pressure stroke, having venting valve at upper end
Inventor: WALLY MICHAEL
IPC: F16K24/04
Filed: 1992-06-16
Abstract: The venting valve device (15) has a flow-operated valve (16), the approach condition of which is determined by the aggregate state of the throughflowing fluid.
