Title: Communications in a distribution network
Inventor: TAKEFMAN MICHAEL LEWIS
IPC: H04N21/258
Filed: 1995-11-08
Granted: 2000-05-23
Abstract: A central station (24) of a cable television distribution network (10) transmits TDM frames comprising distribution information and overhead information downstream to customer terminals (26), and determines corresponding upstream TDMA frames by includ-an upstream frame identity in the overhead information of each downstream frame. Each terminal buffers asynchronous information for upstream transmission, and stores an upstream frame identity which it is assigned. On detecting this frame identity in the downstream overhead information, the terminal transmit a buffer queue size in an assigned time slot of the corresponding upstream frame The central station uses the queue sizes from the terminals to allocate time slots in the upstream frames to terminals, by including their terminal addresses in the downstream overhead information, for transmission of the buffered asynchronous information. The central station can also assign time slots to the terminals for transmission of isochronous information.

Abstract: The present invention relates to a clear or translucent stick comprising an electrical light source and a light-refracting tube. The light-refracting tube has a longitudinal axis and is made of a translucent or transparent plastic material. The tube tapers from a first open end to a second closed end. The light source is mounted in the open end of the tube with the power source housed in an adjoining cap which may be fitted onto the open end. The light source includes a LED aligned with the longitudinal axis of the tube, and a refracting network is formed on the internal surface of the tube to project light emitted by the LED towards the sides and the closed end of the tube. This network consists of a generally helicoidal thread. In operation , the light rays are concentrated and refracted by the thread and the translucent or transparent material forming the tube appears to glow evenly along its entire length. This threaded and tapered surface is particularly relevant and interesting since it allows easy disengagement of the tube from the plastic injection mold and works efficiently with many different electrical light sources. Optionally, the external surface of the tube includes a plurality of longitudinal triangular or arced projections to improve uniform light distribution along the tube.

Abstract: On charge du N-phosphonométhylglycine solide ou de l'acide de glyphosate sous forme d'un "gateau humide" dans un mélangeur/réacteur approprié. On place ensuite un équivalent stoechiométrique d'ammoniac dans le mélangeur pour assurer sa réaction directe avec l'acide de glyphosate lors de son agitation à l'intérieur du mélangeur. Une chemise d'eau contenant de l'eau de circulation ou tout autre moyen approprié facilitant l'échange thermique, bien connu par ceux versés dans l'art, est adaptée au mélangeur et utilisée pour extraire du réacteur la chaleur produite par la réaction exothermique. La teneur en humidité du gâteau de glyphosate humide, la conception du mélangeur présentant, de préférence, une relation de tolérance étroite entre les parois intérieures du réacteur et les palettes d'agitation, ainsi que l'emplacement relatif de l'entrée de l'ammoniac dans le mélangeur/réacteur et le maintien d'une température de réaction à une valeur inférieure ou égale à environ 60 ·C constituent des variables de procédés importantes. Le glyphosate d'ammonium ainsi produit est une poudre soluble à l'eau, présentant une forte sorption, et pouvant être utilisée, en produit final, comme régulateur de la croissance des plantes ou désherbant sans autre traitement. Toutefois, compte-tenu du pouvoir de sorption élevé du produit de réaction, toutefois, il convient particulièrement pour d'autres formulations pour absorber/adsorber un taux exceptionnellement élevé d'adjuvants tels que des agents de mouillage, des agents anti-moussants et, en particulier, des agents tensio-actifs.

Abstract: In a regulation- or control process speed steps are predetermined for the displacement of a movement unit and a reference-speed-curve determined out of it. Means for calculation detect out of it a reference-curve of the path (s) over time for determination of a position reference variable for the speed regulation or -control. At the time (t l) determined for the modification position (s i) for switching between contiguous speed steps, the speed of the drive motor (44) is maintained until the comparison means determines, that the movement unit has reached the modification position. When the modification position (s i) has been reached, the reference position value curve is triggered (Fig. 9) at the switching time.
