Title: Method and circuit arrangements for recoding moving-image signals
Inventor: KUMMEROW THOMAS DR
IPC: H04N7/36
Filed: 1983-03-18
Abstract: To save transmission capacity, only those parts of a frame of a moving-image signal (video signal) are transmitted in digital form which have changed compared with the preceding frame as far as this is known to the receiver. The transmission coding process can run at a continuous operating speed determined by the data rate of the transmission path since both change decisions and the supplied uncoded image data words are temporarily stored and, after a variable delay, are supplied to the coding process for the data processing on the transmitter side. A channel-side buffer storage can be omitted both in the transmitter and in the receiver. The received image data are directly decoded and the associated address data are used for updating the image information located in the frame buffer, which information is only reproduced after a delay time - between zero and one frame period.

Title: Device for compensating for temperature-induced displacements of a work spindle relative to a rule attached to the spindle slide at a distance from the work spindle
Inventor: BORER WERNER
IPC: B23Q11/00
Filed: 1983-06-07
Abstract: To compensate for the thermal expansion in the longitudinal direction of the spindle slide (4) and the spindle head (2) of a machine tool, a rule (6) is attached to the spindle slide (4) in a longitudinally movable manner and, via a double-arm lever (9) pivotably attached to the spindle slide (4), is connected to a push rod (22) lying parallel to the rule and made of a material with a low coefficient of thermal expansion, the other end of which push rod (22) is anchored to the spindle slide (4). Relative movements between the anchorage (24) of the push rod (22) and the anchorage (17) of the lever (9) result in pivoting of this lever (9) and thus in a compensating longitudinal displacement of the rule (6). The compensation is here effected as a function of the thermal expansion or contraction of the spindle slide itself, which in a simple construction leads to compensation working with minimum inertia. <IMAGE>

Patent DE-3336555-A1 (DE)
Title: Method for frame synchronisation of demultiplexers
Inventor: SZIGETI TIBOR DIPL ING
IPC: H04J3/04
Filed: 1983-10-07
Abstract: For the frame synchronisation of demultiplexers and for recovery of the clock alignment information at higher bit rates in time-division multiplex systems, the internal clock frequency (T/a), which is used for controlling the synchronous counters (Z2 to Z4 in Fig. 1) required for framing, is a-times lower than the clock frequency (T) of the overall time-division multiplex system. The dividing factor a is integral and greater than 1, for example a = 4. Frame synchronisation is effected with the first incoming synchronisation pulse "line" (SPL). The further "line" synchronisation pulses (SPL) which arrive during the synchronous state are suppressed. Using synchronised frame control signals, two bit streams of 68.750 Mbit/s and 2.048 Mbit/s are preferably recovered from a multiplex bit stream of 71 Mbit/s. <IMAGE>

Abstract: The invention relates to a sack, preferably made of plastic film, in particular a sack with a valve, whose bottom parts are formed by folding the transverse side walls inwards and folding the longitudinal side walls on top, each bottom part being sealed by a covering sheet applied on the outside. The invention is based on the object of improving a sack of the generic type described above such that it can be opened to form a pouring opening which can be closed again. According to the invention, this object has been achieved in that at least one end region of one of the bottom parts has a coating which extends at least up to the inwardly folded end of the transverse side wall and weakens the adhesion of the covering sheet.
Patent DE-3339224-A1 (DE)
Title: Loading platform
Inventor: BRANTNER HANS ING
IPC: B62D33/03
Filed: 1983-10-28
Abstract: In order, in a loading platform having at least one tailgate which is arranged in the region of one of the boundary edges of the loading platform and can be folded down about an axis which is arranged underneath the loading platform and is parallel to the boundary edge and whose end region, which is adjacent to the boundary edge and is provided with a downwardly descending curvature, projects beyond the tailgate bearing of the said loading platform, to prevent residual loading material becoming jammed between the tailgate and the loading platform, the invention proposes that the tailgate 2 should have at its end directed towards the pivot axis 4 a shearing edge 7 which interacts with the curved end region 5 of the loading platform 1 and can be moved along the curved end region 5 and whose pivot radius is greater than the curvature of the end region 5, the shearing edge 7 being seated on the loading platform 1 when the tailgate 2 is folded up. <IMAGE>

Title: Method and apparatus for producing a wide rise heading by means of a drum shearer
Inventor: BRANDENBURG HELMUT ING GRAD
IPC: E21C35/24
Filed: 1983-11-05
Abstract: The invention relates to a method and an apparatus for producing a wide rise heading 3. According to this method, a drum shearer can be moved in a reciprocating manner over the width of the rise heading 3 on a conveyor 2 movable in the direction of working and is designed either as a single-drum shearer 1 or as a double-drum shearer 11, the shearing drum 9 or shearing drums 16, 17 of which are mounted in a vertically adjustable manner on supporting arms 8, 14, 15. This drum shearer 1, 11 is constantly moved back and forth over the length of the machine travelling track while the conveyor 2 is continuously advanced, and, at both ends of the machine travelling track, just before reversal of the travelling direction of the machine, the working plane of its single shearing drum 9 is automatically changed while constantly maintaining the pivoting direction 29 of the supporting arm 8, or else, in the case of double-drum shearers 11, the working planes of the two shearing drums 16, 17 are interchanged. Therefore the shearing drum 16 previously cutting at the floor now performs a roof cut or/and the shearing drum 17 previously working at the roof now cuts at the floor. In the process, the travel of the conveyor 2 in the direction of the working face during the reciprocating motion of the drum shearer 1, 11 is to correspond to the shearing-drum width. <IMAGE>

Title: Method and device for detecting leaks in sealed containers
Inventor: KLUGE GUENTER DIPL ING DR
IPC: G01M3/20
Filed: 1983-11-08
Abstract: In this method of detecting leaks in a sterile package, the sterile package is evacuated and, after being partially filled with an inert gas, is placed in a test chamber. The test chamber is then evacuated down to a low residual pressure and the residual gas in the test chamber is sucked off and fed through a mass spectrometer. As long as water is present in the package, a predetermined final vacuum value is not reached in the test chamber as a consequence of water vapour escaping from a leaky package. In the case of small leaks, inert gas, which may be, in particular, helium, escaping from the package is detected in the mass spectrometer and indicated.

Title: Anchoring for a tensible tension member, e.g. an inclined cable for a cable-stayed bridge
IPC: E01D19/14
Filed: 1984-03-22
Abstract: In an anchoring for a tensible tension member consisting of a number of individual elements, e.g. an inclined cable for a cable-stayed bridge, the individual elements are anchored at the ends in relation to an anchor plate (17) which is supported on a support sleeve (15). In the cavity (16) formed by the support sleeve (15), the individual elements (8) are surrounded by a tightly fitted mass of metal grains (21) which in a three-dimensional state of stress form support vaults between the inner surface of the support sleeve and the individual elements. This state of stress is created by a pressure plate (22) closing off the cavity (16) being acted upon with pressure in the longitudinal direction of the tension member by a tension rod (24) passing through the support sleeve (15). The state of stress between the metal grains can thus be created by additional means applied from outside so that the desired distribution of the force transmission is already present over a greater length of the tension member when the dynamic loading occurs. <IMAGE>
