Title: Roller bearing design with curved surfaces on rollers
Inventor: TSUTSUI AKIRA
IPC: F16C33/36
Filed: 1995-08-30
Abstract: The rolling surface (3a) and the radiused part (Rb) between surface (3a) and endface (3b) go smoothly over into one another via a first bend (R1), using a second bend (R2) as the smooth transition between the radiused part (Rb) and the endface (3b) of the roller (3). Surfaces (3a,3b,Rb) are all ground simultaneously by a tool having suitably shaped surfaces to grind those of the roller (3), assisted by corresponding bend areas between the tool surface used to grind the rolling and endfaces. A bearing has ground rollers held between outer and inner rings, and the centres of the radii of curvature of the radiused tool part of the respective rollers lie on the boundary between the rolling and radiused parts. In this way the radius (R1) from the centre line of the bearing roller at the centre of the radius of curvature of the radiused part of the roller corresponds to the radius of the roller endface.

Title: Integrated multi-axis processing machines measurement monitor e.g. for glass-processing machines
Inventor: KOENIG WILHELM
IPC: G01B5/04
Filed: 1996-06-15
Abstract: A multi-axis production measurement monitor consists of a ball-and-cup multi-sensor (1) fixed in direct line of sight (3) to the surface of a scaled spherical multi-reference provider (2). Both of these are placed in fixed positions in relation to the object to be measured during production (e.g. wine glass, turbine blades) and to the movement axes during the production process on a multi-axis machine. The mid-point of the object should be along the length of each line of measurement. Thus a laser beam transmitted from sensor to reference will detect any failure to correspond to the correct length measurement, i.e. deviation in the movement on any axis. This simultaneous measurement along all axes reduced quality control time. A drive may be linked to the reference to help to reduce production time also.

Abstract: The appts. to process vegetable fibres, to give fine structured fibre masses, has ground steel blades fitted to a holding shaft and rotating carrier arms or directly on a rotary axis, and at right angles to the axis in a rigid mounting or a fitting which allows limited rotation.  The blades rotate at a high speed, of min. 4000 rpm, to give a pulsating beating action on the raw fibre mass, to break down the material into fibrils through the direct cutting action and the inner friction and resulting draw forces across the main line of the fibre bundles.   Also claimed is an appts. with blades fitted directly to a roller or to carrier arms with hook or claw holders.  They rotate at high speeds to beat against the raw fibre mass moving on a guide plate.
