Title: Signal encoder selecting suitable signal transformation - selects output from parallel connected transformation unit having greatest measured energy and encodes
IPC: H04N7/26
Filed: 1992-12-07
Abstract: The encoder includes a transformation assembly (2) with several types of transformation units (TF1...n) for converting a signal (1) into transmission data by receiving the signal via separate paths. An energy detector (3) transmits a selection signal (a, a') for such transformation with the highest energy content after the energy detector has determined the energy from the respective transformation units. A multiplexer (4) transmits the signal with the highest energy from the respective transformation units under the control of the selection signal (a) from the energy detector. The latter detects the energy from the coefft. of an energy detecting range, corresp. to the transform range data of low frequency. USE - For improving transmission efficiency of video signal, e.g. using discrete cosine or Kahrunen-Loeve transformations.

Title: Method and appts for bottom tapping of a ceramic-free melt for production of metal powders - through a bore in a metal disc fitted into the bottom aperture of the crucible.
Inventor: DINTER HANS-PETER DIPL ING
IPC: B22F9/08
Filed: 1992-12-09
Abstract: Appts for bottom tapping of a ceramic force melt includes a container (1) with a bottom aperture (15) for accommodating a metal 'button' made up of a Ti/Al alloy melted by means of a burner (3) such as, for example, a plasma gun mounted above the container. The appts is characterised by a metal disc (15) pref of copper with an outlet bore (17) fitted into the aperture (15). Melting of the 'button' takes place with the plasma current rising steadily (for example, from 450 A to 1000 A). Outflow through the bore commences and is completed at a maximum constant plasma current (1420 A, for example). The bottom configuration of the metal 'button' to be melted is made to suit the configuration of the metal disc (16), in order to prevent premature flow of the metal through the disc bore. The disc has a protruding rim (18) to prevent it from slipping through the aperture (15) and to improve its cooling. The bottom rim of the bore (17) is provided with a chamfer, a step or a counterbore. USE/ADVANTAGE - For production of high-purity metal powders. Extremely thin jets of molten metal can be produced without freezing-in danger.

The signal generating device is a flow sensor (6) arranged in the line (7) from the T-connection of the valve (2) to the tank (5). The signal of the flow sensor occurs according to the reduction or absence of flow through the line. USE/ADVANTAGE - E.g. for use in tightening and loosening hydraulically operated nuts. Hydraulic circuit eliminates disadvantages of conventional circuits, e.g. long response times.

Title: Switch device receiving and processing FM data
Inventor: ROTHARDT FRANK
IPC: B61L3/14
Filed: 1994-02-03
Abstract: The processed data are conveyed to the control loop via an internal data line for conversion into control commands for the drive unit. The device has a first circuit to generate the current data signal level and a second circuit to generate a reference signal level. A third circuit receives a first input signal representing the current signal level from the first circuit and a second input signal representing the reference level from the second circuit. The third circuit compares the first and second input signals and provides an output signal which suppresses the processed data when the comparison determines that the first input signal represents a current signal level which is less than a predetermined fraction of the reference level. The second circuit adapts the reference signal at predetermined intervals to the current level of a data signal which is continuously received over a given period.

Furthermore, a spinning station (18) is shielded from outside by separators (143b, 143c) as well as partition walls (164b, 164c) and a door (165). Air can pass from below only through the interspace between the ring (162) and the spindle (31) which is wound with thread (161). On account of the negative pressure in the collector (14), air is sucked in from above in the direction of the arrows (22a and 22b). Heat and fibre fly occurring in the region of the spinning stations are thereby discharged completely out of the casing through the front orifice (148c). <IMAGE>
