Title: Pendulum striking mechanism for the generation of defined impulses for the dynamic calibration of compressible bodies
IPC: G01N3/32
Filed: 1988-06-04
Granted: 1989-11-16
Abstract: A description is given of a pendulum striking mechanism for the generation of defined impulses for the dynamic calibration of compressible bodies and especially of copper compressible bodies, in which the impulse generated by the pendulum acts on the compressible body via a force transmitting element and a force pick-up detects the progress with time of the force acting on the compressible body. The pendulum striking mechanism according to the invention is characterised in that, for altering the progress with time of the impulse, the force transmission element has a first and a second ram of predeterminable diameter which are in effective connection via a space filled with a fluid, and of which the first can be loaded with the impulse generated by the pendulum, and the second is in effective connection with the compressible body.

Granted: 1991-06-20
Abstract: Electric shaver and haircutter (1) having a first, shaving part (6), consisting of lower cutter and upper cutter, for cutting short hair and a second, shearing-comb head (5), formed from shearing cutter and shearing-comb plate, for shortening long hair, a distance comb (8) being mountable on the first and second cutting system for use of the shearing-comb head (5). On setting into operation, the shearing-comb head (5) is basically displaced, via a switching slide (10) which can be employed for the on and off position, from its lowermost position (off position), in which it exhibits the maximum distance (A) from the comb tip, to the uppermost position at a minimum distance (B) from the comb tip, in which the cutting length is shortest. In this way, it is ensured that, on setting the shearing-comb head (5) into operation, the cutting of the beard hair begins at the greatest cutting length. It is thus possible to prevent a path from being unintentionally cut in a relatively long beard by the operator as soon as the appliance (1) is switched on.

IPC: H04L12/26
Filed: 1992-01-31
Granted: 1993-08-19
Abstract: The invention relates to a process for recovering transmitted test data in cellular digital streams at the receiving end in which the test data are coded by means of code words which, in self-correlation, generate a Dirac pulse and in which a cross-correlation is undertaken on the reception side for decoding. In order to be able to transmit a larger number of test data in coded form, a binary zero word (stored at St=1) is added to the code words on the transmission side and the various test data (e.g. 11101) are allocated to the various code words and the zero word. The sum of the digits of the code words received and the zero word is made in addition to the cross-correlation on the reception side.

Inventor: BRUNDERT MARTIN DIPL ING
IPC: H04B10/43
Filed: 1994-10-27
Granted: 1996-08-01
Abstract: A system is disclosed for point-to-multipoint data communications between a central station and a plurality of terminals connected to each other and to the central station by a network, in particular a passive optical network. Data transmission is carried out by time division multiplexing (TDM/TDMA). The central station has a d.c. coupled receiver with an amplifier for the optoelectrically converted signal, a memory for storing at each terminal a value corresponding to the peak value level, and a comparator that compares the signal to a reference voltage (V ref) derived from the peak value level of the corresponding burst and derives therefrom the digitalised signal. In order to reduce hardware complexity, the amplifier has a plurality of parallel amplifier units with constant amplification factors (G1, G2) that are alternatively selected by the control unit depending on the previously stored value of the peak value level (V peak) of the corresponding burst. Another comparator compares the amplified signal to the peak value level of the corresponding burst so that when a deviation is detected the stored value of the peak value level and the amplification factor for the present burst are adapted step by step.

Title: Method and device are for tuning tongue mechanism in organ pipe and regulate accurately tone level frequency by means of lever tippably fitted around axis forming part of support which in turn forms part of frame
Inventor: DOBMA CEES
IPC: G10B3/08
Filed: 2002-08-20
Granted: 2004-02-24
Abstract: The method and device are for tuning a tongue mechanism in an organ pipe and regulate accurately the tone level frequency by means of a lever (2) tippably fitted around an axis (4) forming part of a support (4a) which in turn forms part of a frame (1) displaceable along the wind chest of the organ mechanism. The lever at some point engages with a ridge (5a) on the crank (10) of the tongue mechanism to be regulated of the organ pipe being tuned.  The lever at another position, with the aid of a movement mechanism, can be tipped around the axis, whereby the static part of the movement mechanism forms part of the frame and is displaceable along the wind chest of the organ mechanism. This movement causes the engagement point of the lever on the crank to be tuned accurately to move in the movement direction of the crank. This causes the crank of the tongue mechanism to be accurately regulated to the inherent frequency of the tongue to the correct tone level frequency of the organ pipe.
