Title: Noise generator for radio channel simulator - uses summated weighted outputs of shift register stages to provide Doppler spectrum
Inventor: SCHOEFFEL PETER DR ING
IPC: H04B17/00
Filed: 1991-03-13
Abstract: The noise generator uses a feedback shift register (SR), with each of its output signals (A1...An) multiplied by a weighting factor (G1...Gn), before being summated by an adder (A). The weighting factors (G1...Gn) correspond to the inverse Fourier transformations of the doppler spectrum. The doppler frequency is varied by varying the clock frequency (T) supplied to the shift register (SR), or by varying the weighting factors (G1...Gn). Pref. the output of the adder (A) is fed through a low-pass filter (F). ADVANTAGE - Reduced complexity, allowing reproducible measurements.

Title: Fitting twist-off type lids to containers - involves two endless belts which rotate lid to tighten it.
Inventor: EWALD OTTO
IPC: B67B3/20
Filed: 1991-10-01
Abstract: The machine for fitting `twist-off' type lids to containers has a conveyor formed by a first endless belt (7).

Patent DE-4222085-A1 (DE)
Inventor: FISCHER-HELWIG FRANK
IPC: B02C4/28
Filed: 1992-07-04
Abstract: The structure of the surfaces of the grinding rollers (1) of two-roller machines is important for the drawing-in behaviour of the material to be ground and therefore for throughput and comminution. As the surfaces of the grinding rollers are subject to wear, when abrasive materials are ground in particular, and inhomogeneities in the grinding material can cause the removal (5) of the surfaces of the grinding rollers, assessment of the state of the surfaces, which is carried out visually, is important, but is made difficult by the rapid speed of rotation of the grinding rollers and by frequent adhesion of the ground material, and can therefore only be carried out when the grinding rollers (1) are stationary. It is proposed to carry out measurement of the surface structure in a contactless fashion using an electronic transducer (3) during operation of the two-roller machine, the measuring signal not being affected by non-magnetisable ground material which is adhering to the grinding roller (1). <IMAGE>
