A rotary brush sweeper (10) includes a debris pan (22) with an inlet portion (85) that glides on a surface being cleaned. The debris pan (22) automatically disengaged from the sweeper (10) upon being engaged by an obstacle in the path of the sweeper. The debris pan (22) is configured with an inlet portion or scoop (85) for directing debris propelled by a rotary brush (20) into the debris pan. The ...

Date Apr. 21, 1988.An image processing method for flame monitoring is based on the formation of a video signal characteristic to the combustion process. In accordance with the method, the flame is monitored by each fire-box camera essentially from its side, whe...

A carbon dioxide laser (4) directs a beam (6) onto a ceramic workpiece to be treated (18), which workpiece moves along arrow (20). A carrier gas injector (14) injects a moderate throughput of spheroidized powder of a ceramic material into said beam. After melting and solidifying, the layer (24) after has microcracks which are smaller than they would have been if there had been no projected powder....

In a precision adjustment head for a machine tool a slide (9) is radially adjustable in a radially extending guide (8) in a substantially cylindrical housing (1), on which slide a tool carrier (11) can be fixed. In the housing (1) the positioning member 5 is axially displaceable and a positioning element (14) is fixed to the slide (9), with a groove (15) extending obliquely to the housing axis A a...

For rapid coupling of a flexible or rigid tube 1 to a connection 8, the latter has a cutout with an O-ring 6 in a groove in its wall. Connected axially non-displaceably but rotatably to the connection is a sleeve 3. The opening of the sleeve, which is coaxial with the cutout of the connection, accommodates a coil spring 4, one end of which is connected to the sleeve 3 and the other end of which is...

Two circular cutters (6,7) are located for rotation in a plane extending at right-angles to the longitudinal axes of the frame arms (2,3). At least the one cutter shaft (17) is displaceable towards the shaft (8) of the other cutter to adjust a suitable gap between the cutter edges. Between the frame arms is a guide fillet (23) which extends at right-angles to the longitudinal direction of the arms...

Between the earth conductor (10) connecting point (1) in the connector and the corresp. contact (11) is coupled an extendable electrically conductive component. In the event that the connector or the cable (3) connected to it is subjected to tractive force tending to break the contact between the cable leads and their connection points, the earth circuit is maintained intact, at least until contac...
