Title: Point-to-multipoint cellular television transmission system
Inventor: KOOL LEO
IPC: H04W16/30
Filed: 1995-05-03
Abstract: Known is a low-power point-to-multipoint cellu-lar television transmission system (1) in which transmit-ter stations (T1, ..., T19), which are located in centres of cells (C1, ..., C19) of the system (1), comprise omni or quadrant-directional transmitting antennas transmitting to receiver stations (R1, ..., R8) located in the cells.  The known system operates in the microwave band.  Such a system architecture gives either rise to a transmitting antenna which is difficult to manufacture or in itself is rather complex and thus relatively expensive.  A sys-tem architecture is provided which can be easily imple-mented and which avoids using omni directional anten-nas.  To this end the transmitter stations (T1, ..., T19) are located at the circumference (CF) of their cells (C1, ..., C19) of the cellular sytem (1), and each transmitter station is provided with a directional antenna (TA1, ..., TA7) covering its cell.  Preferably, the transmitting  an-tennas (TA1, ..., TA7) in the system generally transmit along a main geographical axis (ax) of the system (1). Each program to be transmitted can be transmitted via a separate channel and a separate radiator (TA1a, TA1b, ..., TA1i). Then, the channels are completely indepen-dent to each other.

Title: Interpretive measurement instrument
Inventor: OATES JOHN DAVID
IPC: G07C3/00
Filed: 1994-08-26
Abstract: The present invention discloses a measurement instrument incorporated in an IBM PC environment which is capable of interpreting the measurements made or sampled so as to provide a predictive or diagnosis conclusion. A classification procedure is carried out on all the measurements taken in a specific time period, an epoch, which can be as short as the measurement sample period. The classification procedure-gives rise to the predictive or diagnostic capability. This procedure can also be used in a feedback control arrangement.

Abstract: A back support (20) for a bath lift features a pivot-mounted backrest (24) which can be supported by a swivel arm (28). The swivel arm (29) has a laterally protruding runner (32) which engages in a slotway (34) of a tee web (36) on the backrest (24). In the bottom portion of a longitudinally extended slotway section (48) is an adjoining bypass track section (54) which forms a track loop featuring a non-return stop (56). The backrest (24) can be rotated forwards slightly beyond its inclined position and thereafter pushed back into its supported inclined position. A subsequent brief release rotation in the forward direction causes the runner (32) of the swivel arm (28) to pass over a non-return stop (56) and into the bypass track section, as a result of which the backrest is released for rotating downwards towards the flat position.

Title: Efficient production of landplaster by collecting and classifying gypsum fines
Inventor: VOORBERG DENNIS B
IPC: F26B17/10
Filed: 1997-04-02
Abstract: A landplaster production method includes the steps of providing a supply of particulate gypsum material, drying the gypsum material by passing a stream of heated air thereby as the material is rotated, classifying and separating the dried particles into fines and coarse particles, collecting the suspended fines in a collector, passing the coarse particles to a grinder such as a roller mill for reducing the particles, and mixing the reduced particles with the collected fines for processing into landplaster. The elimination of fines from the feed to the grinder results in significantly greater production by increasing the efficiency of the grinder. Further, the dryer is modified to agitate the dried gypsum material so that it may be more easily introduced into the classifier/separator situated adjacent the drier discharge outlet.

Abstract: Unité de commande pour des pulvérisateurs agricoles, qui utilise un détecteur (23, 123, 148) pour générer des signaux de couleur rouge, verte ou bleue sur un champ de vision. Les signaux de couleur sont utilisés pour générer un signal de sortie "vert" ou "non vert" destiné à commuter une buse de pulvérisation (13) lorsque quelque chose qui semble être vert a été détecté. L'algorithme qui détermine s'il existe quelque chose de "vert", plutôt que "non vert" examine le niveau de la composante verte par rapport aux composantes rouges et bleues dans le signal de couleur, et si lesdites composantes sont dépassées, la décision l'emporte pour le "vert". Le niveau de vert dépassant les niveaux de rouge et de bleu peut être comparé à des valeurs préétablies pour déterminer la sortie "vert", "non vert". On peut établir le niveau de vert en additionnant les pixels un par un sur une zone donnée à l'intérieur du champ de vision considéré pour voir si la somme pour la zone donnée dépasse un niveau déterminé en vue de décider que cette zone est "verte" et exige une pulvérisation.
