Patent DE-4209756-A1 (DE)
Title: Rolling track curve with  successive bearing rollers - has endless flat belt guided over curved path engaging with one flat side on bearing rollers to drive same.
Inventor: AXMANN NORBERT
IPC: B65G13/07
Filed: 1992-03-26
Abstract: The belt is pressed onto the bearing rollers (14) and is guided over support rollers (20) which are arranged in the area of the entrainment sections (16) of the bearing rollers under same and between each two successive bearing rollers. The axes (22) of the support rollers (20) are inclined relative to the rotary axes (23) of the bearing rollers so that the inner edge (25) of the flat belt is pressed more strongly than the outer edge (26) into the free spaces between the adjoining bearing rollers and is thus forced into a wavy motion as the belt rotates. The support rollers (20) pref. have on the side facing the centre of the curve (10) a marginal flange (24) which prevents the flat belt from sliding off from the support rollers. USE/ADVANTAGE - Less wear on conveyor belt on curved track.

Title: Method and apparatus for cutting a brittle body with laser radiation
Inventor: BOLLMANN DIETER DIPL PHYS
IPC: B23K26/066
Filed: 1993-02-19
Abstract: The cutting of brittle bodies, in particular hollow bodies or plates, for example of glass or ceramic, is widely used in technology. During the cutting operation with laser radiation, it is desirable to input as large a heating capacity as possible without exceeding in the process the maximum permissible local power density at the cutting line. In the method described here, the body to be cut is heated at the surface along the cutting line by the action of the laser beam in such a way that a thermo-mechanical stress builds up which leads to the fracture of the body at this cutting line. According to the invention, the laser beam is formed in such a way that the beam cross-section acting on the surface of the body to be cut has an elongated shape along the cutting line, the ratio of length to breadth being adjustable. The method and the apparatus can be used, for example, to cut off the pressed margin of drinking glasses, the glass rotating in the fixed laser beam.

Title: Screwing apparatus
Inventor: BERGLER ULRICH
IPC: E21B1/30
Filed: 1993-07-13
Abstract: The hand tool comprises a driven drive part (6), a ring gear (9) as well as a plurality of rotating elements (7) arranged between the ring gear (9) and the drive part (6) and on a carrier (8). The carrier (8) is fixedly connected to a tool spindle (10), the tool spindle (10) being displaceable in the axial direction together with the carrier (8). When driving a screw into a corresponding underlying surface, a pressing force is exerted upon the hand apparatus. This pressing force causes axial displacement of the tool spindle (10) together with the carrier (8) relative to the housing (1) of the hand apparatus. In this process, the ring gear (9), the drive part (6) and the rotating elements (7) come into frictional connection with one another. The rotary movement originating from the drive part (6) is transmitted to the tool spindle (10). <IMAGE>
