Patent DE-19501652-A1 (DE)
Title: Frequency ramp generating method
Inventor: EBERMANN JOACHIM DIPL ING
IPC: G06F1/025
Filed: 1995-01-18
Abstract: Frequency ramps are generated between a start frequency (fi) and an end frequency (f2) in a partial time interval (ti). The partial time interval corresponds to the period (Ti-1)of the frequency (fi-1) of the previous pulses. The individual pulses are integrated to an absolute ramp time (tr), and then multiplied by a predetermined acceleration value (a) for the actual pulse of the frequency (fi) to be reached. The period (Ti) is obtained form the reciprocal of the frequency (fi). The ramp time (tr) is set to a start value of 0 during the partial time period before the ramp starts.

Title: Removal and transfer of signature etc. stack, using gripper
Inventor: GAEMMERLER HAGEN
IPC: B65H31/30
Filed: 1995-02-13
Abstract: The gripper (3) is moved to the signature stack (12) such that a top gripper unit (4) is located over the stack and the lower gripper unit (5) is located under the stack. The stack is gripped by hoisting the lower unit and setting the top one onto the stack. Then the turntable with the gripper is rotated up to a second station, where the stack is treated or deposited. The gripper is opened and moved out of the second station. During the retraction of the gripper, prior to motion to second station, the stack is pulled onto a deposition surface, where it stays during the rotation of the turntable. On the approach of the gripper it is pushed onto a treatment or deposition location.

Patent DE-19529399-A1 (DE)
Title: Input signal processing circuit - has clamping circuit for detecting amplitude demodulating signal during measuring interval
Inventor: NIEKE NORBERT
IPC: H04H20/34
Filed: 1995-08-10
Abstract: The input signal contains a first amplitude demodulated signal (ARI), which contains a carrier. A second amplitude demodulated signal (RDS) has a suppressed carrier arrangement. The RDS signal processing takes place, dependent on the presence of the ARI signal. A clamping circuit detects the ARI signal in the input signal, during a preset measuring time interval, and tests it for an uninterrupted, constant level. In the positive instance, the circuit replaces the ARI signal, after the measuring interval, by a fixed value signal with the ARI signal level for further processing, until a new ARI signal detection is triggered by a resetting signal.

Title: Activation of movement alarm using at least one IR sensor giving one electric signal
Inventor: ROSCH RAINER DR ING
IPC: G08B29/18
Filed: 1996-02-29
Abstract: The method of alarm uses at least one IR sensor (1), which determines the heat radiation emanating from a heat-emitting object (14). The electric signal is led to a signal former (2-6) and evaluated, also correlated with a further signal for suppressing interference signals. For the correlation, a first sensor signal is multiplied with a second sensor signal, which is shifted about a variable time ( tau ), and in addition is integrated. As a result of this auto-correlation, resulting main and/or sec. maxima are called up in a manner, for deciding the activation of an alarm, such that an alarm is only activated, if the main and/or the sec. maxima, fulfil at least two important decision criteria.

Patent DE-19620196-A1 (DE)
Inventor: SIEGERT KLAUS DR ING
IPC: B21D22/00
Filed: 1996-05-20
Abstract: The invention relates to a process for shaping a flat metal workpiece, especially an aluminium sheet, in which the workpiece is heat-treated in the shaped region. According to the invention, the heat treatment is applied by a radiation tool and the shaping is performed after the heat treatment, but within a period in which the material of the workpiece still has an increased capacity for expansion. It is thus possible to heat-treat a relatively narrowly spatially limited shaping region on the workpiece with uncomplicated equipment. The overall process can be made more flexible owing to the time shift between heat treatment and shaping.
