Title: Method for the automatic detection and classification of digital quadrature-amplitude-modulated signals having unknown parameters
Inventor: LIEDTKE FERDINAND DR ING
IPC: H04L27/00
Filed: 1988-10-10
Abstract: This method is intended for monitoring the radio traffic, for example by the post office. The received signal is digitised and, with prior knowledge of the frequency bandwidth in one or otherwise in a number of parallel channels of different frequency bandwidth, is separately processed further. In each channel, the signal element timing is extracted and the instantaneous values of amplitude, frequency and phase are sampled at the signal element timing points. Mean values and variances of the amplitude and frequency values are determined. Using the amplitude values, the frequency values and the differences of successive phase values, histograms are formed. The histogram forms typical of the wanted signal types are automatically detected by cross correlation with predetermined reference function sets which are typical of the modulation. To increase the reliability of decision, the mean values and variances between amplitude and frequency are simultaneously checked for the maintenance of predetermined value ranges. The classification of the signal type is obtained from the reference function set which leads to the highest correlation results in the histogram analysis. The signal element rate is estimated from the frequency bandwidth of the associated channel.

Patent DE-3900842-A1 (DE)
Inventor: RUTKOWSKI CHRISTIAN DIPL PHYS
IPC: G05B19/4069
Filed: 1989-01-13
Abstract: The basis for the simulation of machining a workpiece (W) by drilling or milling is a computer-internal model in which the workpiece (W) is described by its corner points (A to H) and surfaces (K to P) and a drilling or a milling cycle (T) is described by its enveloping contour. For this, stores (1, 2, 3) are necessary in which information items on the corner points (A to H), the surfaces (K to P) and the enveloping contour (T) are stored. These stores (1, 2, 3) are accessed by a control process (4) which allocates the information items to geometric elements which are stored in main memories (5, 6) and between which an arithmetic unit (7) determines points of intersection and stores these in a separate point-of-intersection store (8). The control process (4) logically combines the information on the previous status of the model, the enveloping contour of the milling cycle (T) and the points of intersection (R, R'; S, S') to form a description of the workpiece after the machining in the computer-internal model and displays it on the display unit (9).

Patent DE-3902730-A1 (DE)
Title: Digital motor
Inventor: SCHILP REINHOLD DR
IPC: F01C9/00
Filed: 1989-01-31
Abstract: The invention relates to a device for driving machines with a high torque and a low driving speed which is continuously variable. The drive has a small overall volume and a low weight relative to the torque produced. It can be of rotational symmetrical construction and be balanced, and this makes it suitable for use as a planetary drive with a rotating housing for the production of a differential speed of rotation. The drive comprises an oscillating motor, the rotary oscillating motion of which is converted by interaction with a freewheel or a ratchet mechanism to a stepwise rotary motion at the output shaft. Hydraulic rotary piston motors, radial reciprocating-piston motors with a toggle mechanism or tangentially articulated reciprocating-piston motors are preferably used as oscillating motors. The drive is preferably used for creeping rotary motion with a high torque, e.g. in machines, machine tools, process machines such as mills, reactors, rotary filters, drum-type driers, solid-bowl helical-conveyor centrifuges, screen-conveyor centrifuges, crystallisers and rotary cement kilns.

Filed: 1989-04-11
Abstract: A plastic drum has a lid and locking ring. The lid engages the opening in the drum with an annular ridge projecting vertically from the underside so that the outer rim of the lid fits the opening; an elastic sealing ring is inserted into the annular groove formed; a projecting flange beneath the opening acts with the locking ring; a sealing ring between the inner rim of the lid and its outer rim is pressed by a metal ring against the upper edge of the neck of the opening and this ring presses down the lid which is engaging the flange. A  (preferably plastic) locking ring with engaging end has a locking groove with spring and closure pin; the clamping arm closure is replaced by the free locking arm which after use, is pressed back against a stop and into its original position by a swivelling spring; the clamping arm pins freely enter their holder by means of a guide, and the drum is closed off in the normal manner. The figure shows the locking ring (31) when opened. Its locking end (21) with groove fits into the locking spring (17) when the ends are brought together, and the closure pin then enters the holder (18). ADVANTAGE - In the design the lid seals off the drum tightly even when under heavy loads. The design of locking ring is inexpensive as its eliminates the normal lever closure whilst it is still utilised in the usual way.
