Title: Method for controlling window displays in an open systems windows environment
Inventor: STAGGS KEVIN PAUL
IPC: G06F3/048
Filed: 1993-06-02
Granted: 2002-01-22
Abstract: The method guarantees the integrity of a process control systems display in an open system windows environment. The process control system includes an interface apparatus to at least one foreign system, and receives display information such that the display information from the foreign systems and the display information from a network of the process control system are displayed on a display unit of the process control system in a windows format in response to control information from the interface apparatus. The interface apparatus transmits the display information of the foreign systems to a display generator unit via a first input channel of the display generator unit. Control information is also transmit-ted to the display generator unit via the first input channel to command a display format to the display generator unit of the display unit. The display format includes a plurality of windows, one of the windows being a control view. The control view (display of the process control system) display informa-tion is transmitted to the display generator unit via a second input channel of the display generator unit. Communication checks are made between the display generator unit and the interface apparatus. If an error is detected by either unit, the first input channel is disabled, and the control view is displayed on the entire screen of the display unit and controlled by the display generator unit, thereby guaranteeing the control view is always displayed and the integrity of the process control system is maintained.

Title: Apparatus for loading flexible tubing with bales
Inventor: PRONOVOST NORMAND
IPC: A01F25/14
Filed: 1993-12-15
Granted: 1995-12-05
Abstract: Bales of hay or the like vegetable material are successively loaded on the frame of a wheeled vehicle and actuate a trip plate which causes a pusher plate to push the bale into the open ended portion of a long plastic flexible tube held folded on an arch-shaped upstanding holding device secured to the rear end of the vehicle.   The bales loaded within the tube successively drop off the vehicle on the ground and react to the backward thrust exerted by the pusher plate on the next bale to cause forward movement of the vehicle.   The vehicle carries its own power supply and is therefore entirely autonomous.  The vehicle has a skid plate and the wheels can be raised so that the vehicle moves on the skid plae to thereby increase resistance to the vehicle forward movement thereby increasing the compaction of the bales  within  the  tube.    The  holding  device  includes  a plurality of tube retaining hook members which are carried by an arch-shaped frame for outward diverging linear movement so as to open the tube.  The tube, which is preferably of the stretchable type,  is stretched by the hook members in a uniform way all around the tube circumference with a minimum of friction on the individual hook members.  The apparatus can handle bales and tubings of various diameters.

Abstract: A process is disclosed for preparing an amorphous ultra-hard material based on boron nitride that is sufficiently hard to scratch diamond. Hexagonal or turbostratic boron nitride hBN is compressed under pressures of at least 70kbar or more and heated up to temperatures of at least 1650.degree.C or more until a molten mass of boron nitride is obtained. The thus formed molten mass of boron nitride is quenched by stopping heat supply, then the pressure on the quenched molten mass of boron nitride is relieved. The hexagonal or turbostratic boron nitride used as feedstock is treated in the presence of crystallisation inhibitors, so that no crystals are formed and the amorphous crystalline structure is condensed by deposition of reaction products such as boron suboxides.

Abstract: An automated demolding apparatus for reliably and repeatedly mechanically separating contact lens mold portions of a mold assembly without damaging the contact lens formed therebetween. The mold assembly includes a first front mold portion having a central mold section with a surrounding flange, and a corresponding second back mold portion also having a central mold section with a surrounding flange. A molded contact lens is formed between the front and back mold portions, and the flanges of the front and back mold portions are spaced apart and parallel to each other. The demolding apparatus includes restraining fingers positioned between and on opposite sides of the spaced flanges of the first and second mold portions and against the flange of the first mold portion. A separating fixture includes separating fingers positioned between and on opposite sides of the spaced flanges of the first and second mold portions and against the flange of the second mold portion. Before demolding, the second mold portion is irradiated by a laser beam, which is absorbed thereby to cause a substantial temperature gradient between the second mold portion and the contact lens being demolded. The temperature gradient causes a differential expansion and shifting of the surface of the heated second mold portion relative to the surface of the lens to lessen the adhesion therebetween to assist in separation of the mold portions, while leaving the lens in the first mold portion. During demolding, the separating fixture is rotated relative to the restraining fingers to progressively separate and peel the second mold portion from the first mold portion.

Abstract: Lors du codage de plusieurs signaux (k1, k2) qui ne sont pas indépendants les uns des autres, la sélection du mode approprié de codage se fait en fonction d'une mesure de similitude. Dans un aspect de l'invention, on détermine la mesure de similitude tout d'abord en codant un des signaux (k1, k2) selon le procédé stéréo d'intensité puis en le décodant, afin de créer un signal (ki1, ki2) porteur d'une erreur de codage. Ce signal, ainsi que le signal non codé correspondant, sont transformés dans la plage de fréquences. Les composantes spectrales réellement audibles aussi bien du signal (ki1, ki2) porteur d'une erreur de codage que du signal correspondant (k1, k2) non porteur d'une erreur de codage sont sélectionnées ou évaluées dans la plage de fréquences en utilisant un seuil d'écoute déterminée par un calcul psychoacoustique. Lorsque le degré de similitude est élevé, un codage stéréo d'intensité est réalisé, autrement les canaux sont séparément codés.
