Patent DE-2520070-A1 (DE)
Title: Ball bearing for torsional resistance - has shaft keyed to sleeve surrounded by balls in cage
Inventor: BEYER RUDOLF ING GRAD
IPC: F16C29/04
Filed: 1975-05-06
Abstract: The ball bearing assembly consists of a cylindrical guide sleeve (1) which forms the housing for a column (4) positioned coaxially in the sleeve. Between the column and sleeve is a ball cage (6) perforated to retain a continuous array of ball bearings (7), all of equal diameter. The column is slotted with a longitudinal rectangular cut-out. An anti-torsion device consisting of a metal strip (3) screwed to the outer sleeve (1) keys the column in the sleeve, preventing both rotation and torsion. Longitudinal movement is permitted, however due to more ball bearings (8) in the walls of the rectangular slot (5). The tolerance is very small, so that play between sleeve and shaft is prevented.

Title: Ceramic blanks deburring machine - exerts smoothing pressure on burrs during movement of blank and tool
Inventor: FREITAG PAUL
IPC: B28B11/18
Filed: 1976-03-10
Abstract: The deburring machine for cast or pressed ceramic blanks generates rapid reciprocating relative movements between the blank and the tool. These movements take place along or in transverse direction to the burrs. The burrs are removed so that neither the traces of the burr itself nor traces of the deburring processes are detachable on the finished ceramic objects. Pressure is exerted only on those surfaces of the blank, which have burrs, at right angles during the relative movement between the blank (28) and the tool (20). The burr is smoothened into the blank and any cutting or scrubbing effects on the blanks within the region of the burrs are avoided. The frequency and amplitude of the relative movement between the blank and tool and the pressure exerted are adjusted so that the material is loaded in the burr region within the range of marked thixotropic behaviour.

Title: Real time processing of sideways looking radar signals - produces useful map display using fast Fourier transform system
Inventor: SCHALLER WOLFGANG DR ING
IPC: G01S13/90
Filed: 1977-03-24
Abstract: A method is used for real time processing of the received signal of a sideways looking rotor. It includes transformation of its video signals into a directly usable map display. The processing system is designed to use currently available technology without necessitating use of a data film with optical correlator. A digital fourier processor (1) is used for the transformation and operates on the fast fourier transform principle. The transformation proceeds on mutually overlapping data blocks successively occuring during movement of the radar along a target region. The overlap intervals are chosen to be large enough to ensure incorporation of a sufficient part of the doppler trains of the targets at the block boundaries in the transformation.
