Abstract: An open office system partition panel assembly including a panel (11) having an outwardly opening wire raceway channel (31) on top with a removable cap (37) to permit wires to be laid in the top raceway channel (31). End wire raceway channels (31, 33) open away from the core (15) of the panel (11) and each has a panel connector support rail (43) closing its opening. The wire raceway channels (31, 33) form a steel frame of box section strength for the panel (11) and all metal-­enclosed, non-snagging wire raceways (31, 33) from the top to the base of the panel. Legs (111) formed as part of the panel base support the panel connector support rails. Wire passageways extend from the panel base to the end wire raceway channels (33). The panel base has an end section (97) fastened to and supported on each leg (111). Upper panel con­nectors (57) facilitate the connection of panels (11), improve the rigidity of the connection between panels (11) and provide positive locking for the panel connection, both vertically and horizontally. The middle section, which fastens to and is supported on the end sections, may be omitted when electrical wiring is not installed in the panel base. A snap-in divider (141) separates the raceway of the panel base into upper and lower wire conduits.

Abstract: Un système de commande de lisses comprend une barre à lisses allant et venant sur son axe longitudinal. Ladite barre à lisses comporte une partie de corps repliable de manière souple faite d'une matière pouvant être magnétiquement attirée, un loquet de retention monté sur la partie de corps, ledit loquet de rétention se déplaçant, pendant le va-et-vient de la barre à lisses, sur un chemin de déplacement entre des première et seconde limites de mouvement de va-et-vient. Ledit chemin de déplacement présente une première zone de mouvement dans laquelle la partie de corps se déplace dans une position non défléchie ainsi qu'une seconde zone de mouvement dans laquelle la partie de corps se déplace dans une position défléchie. Ladite barre comporte également un moyen de came fixe pouvant s'engrener avec un moyen de came sur ladite partie de corps pendant le mouvement de va-et-vient de ladite barre à lisses afin de provoquer le déplacement de la partie de corps de la position non défléchie à la position défléchie, un loquet fixe situé d'un côté de la première zone du chemin de déplacement et agencé pour engrener le loquet situé sur la partie de corps uniquement lorsque ladite partie de corps se trouve dans ladite position défléchie, ainsi qu'un électro-aimant adjacent au chemin de déplacement de sorte que la partie de corps soit située à proximité dudit électro-aimant lorsqu'elle se trouve dans la position défléchie. Lorsque l'on excite l'électro-aimant, celui-ci est capable de maintenir la partie de corps dans la position défléchie à mesure que le loquet se déplace de la seconde zone vers la première zone de déplacement de sorte que ce dernier engrène le loquet fixe.

Abstract: The racing time-keeping apparatus of the video-finish type comprises a CCD photosensitive array (5) which can be read at a specified frequency corresponding to the rate of advance (VI) of the picture of the race. 
<??>The pictures are recorded and displayed by means of a recorder (22) and a monitor (23), commercially available, at a fixed, standardised scanning frequency. Since the frequency of picture capturing by the array is not synchronous with the display frequency, generation of picture segments is undertaken using buffer memories (19, 20), the picture segments next being stored in a picture memory (21) and then read in discontinuous fashion by skipping picture segments in synchronism with a standard TV scanning. 
<??>The apparatus makes it possible to offer a system at low cost price since it uses a recorder and a monitor which are currently available on the market.

Inventor: MARQUARDT RAINER DR-ING
IPC: H02M7/521
Filed: 1990-07-10
Abstract: The invention relates to a method and a circuit arrangement for controlling interruptible converter valves (V1, V2) of a bridge arm (6) of a converter (4) with an impressed DC voltage (UZ), which valves alternately switch on and off as a function of control signals (AV1', AV2'), each of which is generated by a control device (14, 16). According to the invention, regions of the control signals (AV1', AV2') which are generated and provided are gated as a function of the actual load current value (iLx) with respect to two load-current limits (I1, I2), as a result of which new control signals (AV1, AV2) are produced for the interruptible converter valves (V1, V2). This prevents a failure to interrupt as a consequence of excessive depletion layer temperatures of the converter valve (V1 or V2) leading to the converter (4) being short-circuited on the DC side.

Abstract: In an image data compression method to be employed in coding digital image data whose pixels are represented by n bits and which include 2 n  different types of runs, while a run length (ℓ) of a current run is counted, a value representing a run type of the current run is predicted. The prediction is repeated till a predicted value (pr) coincides with an actual value (r) of the run type of the current run. When a predicted value (pr) does not coincide with the actual value (r) of the run type of the current run, a run length for an imaginary run having the predicted value is regarded as zero and the run length 0 of the imaginary run is entropy coded. On the other hand, when a predicted value (pr) coincides with an actual value (r), the actual run length of the current run is entropy coded.
