Patent DE-3714305-A1 (DE)
Title: Device and method for the scanning of surfaces
Inventor: KNOLLENBERG ROBERT G
IPC: G01N21/88
Filed: 1987-04-29
Abstract: A device and method are disclosed for the scanning of surfaces, in order to determine the contamination by small particles or defects on or under the surface of a material. Laser beams with different polarisations are directed onto the surface to be scanned, and the light scattered by the contamination by particles or defects on or under the surface is collected and sampled, in order to obtain electrical signals for this. The electrical signals are then processed and form an output signal for the scanned contamination or the scanned defects. In the illustrated and described embodiment, two polarised laser beams, of which one is a laser beam with "P" polarisation and the other is a laser beam with "S" polarisation, are directed separately onto a monitoring region, so that the beams fall on a common point on the surface to be scanned. The scattered light is then collected and divided into two components depending upon whether they have been scattered from the polarised laser beam "P" or from the polarised laser beam "S", each component being separately sampled whereupon the electrical output signals are processed in order to provide the desired indication.

Title: Automatic brazing apparatus for carbide teeth
Inventor: GERLING NORBERT
IPC: B23K31/02
Filed: 1987-05-25
Abstract: An apparatus for the automatic brazing of carbide teeth to the serrations of a circular saw blade is described in which a rotary table having grooves accommodates a carbide tooth, transports the carbide tooth under a flux-coating station, then transports it to a second flux-coating station where flux is dripped onto the tip to be brazed, and finally puts it into an angular position in which the existing unit is transferred to the brazing holder and moved into the brazing position, in which a serration of the saw blade is pressed from above against the carbide tooth and the brazing operation is carried out by inductive high-frequency heating. The saw-blade mounting device has a spindle, which can be directly driven and accommodates the saw blade, as well as two supply arbors for accommodating unbrazed or brazed saw blades. Tipping is effected automatically by means of a rotatable double arm which simultaneously accommodates an unbrazed or a brazed saw blade at its ends and after rotation into a second position puts down the unbrazed saw blade onto the drive and the brazed saw blade onto the second arbor. <IMAGE>

Patent DE-3739389-A1 (DE)
Title: Drive system
Inventor: WUESTHOF PETER DR ING
IPC: B62D11/06
Filed: 1987-11-20
Abstract: In order to control the rpm of a secondary-controlled drive system which is connected to a line with pressure applied, a torque control circuit is provided whose controller is supplied with the actual value and a set value for the torque occurring at the secondary unit. Depending on the load resistance, a specific rpm for motor and thus speed is established which can be corrected in accordance with the power setting. Thus, an rpm control is simulated which in particular in the case of vehicle drives simulates the driving behaviour familiar from conventional vehicles. Furthermore, for a tracklaying vehicle an rpm control circuit is superimposed on the torque control circuit of the two secondary units which drive the right-hand and left-hand tracks and ensures that at a specific steering lock a specific curve radius is always travelled at irrespective of the travel speed and different friction resistances of the drive tracks.

Title: System for preventing or reducing brake-diving of front-wheel suspension systems (anti-dive system)
Inventor: MICKENBECKER PETER
IPC: B62K25/08
Filed: 1988-10-05
Abstract: Anti-dive systems are presently used above all in motorcycles in an electronically/hydraulically controlled form. These are, however, inter alia, complicated, costly and heavy. The invention is to prevent brake-diving in a simple and reliable manner without excess weight with respect to customary spring forks and without an impairment of the springing characteristics in particular in the case of bicycle suspension systems. Various embodiments of the invention are proposed for various requirements. According to the invention, the force (1) which pulls forwards during braking is caused to oppose the force (2) which effects the brake-diving. As a result, the suspension is unaffected by the braking operation. An embodiment for motor scooters is also described which, inter alia, looks more elegant and is easier to (dis)assemble than known embodiments. The drawing shows an embodiment for a bicycle having a rim brake (3) and a pressure-loaded spring (4). <IMAGE>
