Abstract: Programme compilateur "framework" utilisant un système générique ou un mécanisme de régulation et de classement, et un processeur dorsal générique (pour lequel le générateur de code est spécifique au destinataire). Le processeur dorsal générique englobe les fonctions d'otpimisation, d'attribution de registre et de mémoire et de génération de code. Le système expert générique peut être réalisé sur divers ordinateurs centraux et la fonction génération de code du processeur dorsal peut être ciblée en fonction de l'une quelconque parmi plusieurs architectures d'ordinateur. Un processeur frontal est adapté à divers langages source, tels que le Cobolt, le Fortran, le Pascal, C, C++, Ada, etc. Le processeur frontal balaie et analyse les modules code source et élabore à partir de ceux-ci une représentation en langage intermédiaire ("IL") des programmes exprimés dans le code source. Cette représentation IL est conçue de manière à représenter l'un quelconque des langages code source de manière universelle de sorte que l'interface entre le processeur frontal et le processeur dorsal se présente sous une forme standard et n'est pas besoin d'être réécrite pour chaque processeur frontal ayant un langage spécifique. La représentation IL élaborée par le processeur frontal est basée sur un nuplet en tant qu'élément de base, dans lequel chaque nuplet représente une opération unique devant être exécutée - charge, mise en mémoire, addition, étiquettage, branchement, etc. Une structure de données est créée par le processeur frontal pour chaque nuplet, avec des champs pour diverses informations nécessaires. L'une des caractéristiques de l'invention réside dans son mécanisme de représentation des effets dépendances dans l'interface entre processeur frontal et processeur dorsal; un nuplet produisant un effet s'il écrit dans une mémoire et présentant une dépendance s'il lit d'un emplacement vers lequel un autre noeud peut écrire. Un mécanisme indépendant du langage source est prévu pour décrire les effets de l'exécution du programme. Une autre caractéristique réside dans l'utilisation, dans la partie optimisation du programme compilateur, d'une méthode d'analyse des variables d'induction, dans laquelle l'amélioration consiste à utiliser des ensembles d'effets secondaires utilisés pour élaborer des ensembles IDF. Une autre caractéristiques réside dans un mécanisme pour "repliages constants" (désigné par les termes "K-folding ou KFOLD routine"), constituant l'une des optimisations. Une autre caractéristique réside dans le mécanisme de définition de type, désigné "module TD", qui fournit des mécanismes utilisés par le processeur frontal et le programme compilateur du processeur dorsal dans les informations type de programme de construction devant être incorporées dans un module objet à l'usage d'un éditeur de lien ou d'un metteur au point. Une autre caractéristique est constituée par la méthode de génération de code d'instruction utilisant des gabarits de code selon un procédure multipasse.

Title: Method for improving the transmission of information in the form of data packets, in accordance with a distributed queueing protocol
Inventor: VAN NIELEN MARCUS J J
IPC: H04L12/28
Filed: 1991-05-14
Abstract: Method for improving the transmission of information in the form of data packets, in accordance with a distributed queuing protocol.  By combining the measures according to the invention with time slot erasure techniques and with queuing protocols such as the DQDB (Distributed Queue Dual Bus) and the D3Q (Dynamic Distributed Dual Queuing) protocol, a protocol is obtained with which the capacity of the transmission system can be utilised in a more efficient manner.  To this end provision is made, according to the invention, that each access unit which is able to erase data is able to reset received request bits, the number of request bits to be reset by said access unit being recorded in said access units for the relevant transmission channel and a request bit on a transmission channel being reset by the access unit which receives said request bit if the number of request bits to be reset by said access unit on said channel is greater than the number of request bits still to be transmitted by said access unit over said channel.  In this way requests are prevented from remaining in access unit counters unnecessarily, moreover, by means of the measures according to the invention, the principle of both protocols can also be used in a ring structure, which without said measures would irrevocably lead to considerable problems.

Inventor: MASON ANDREW H
IPC: G06F12/10
Filed: 1992-06-25
Abstract: A CPU executing a virtual memory management system employs a translation buffer for catching recently used page table entries. When more than one process is executing on the CPU, the translation buffer is usually flushed when a context switch is made, even though some of the entries would still be valid for commonly-referenced memory areas. An address space number feature is employed to allow entries to remain in the translation buffer for processes not currently executing and the separate pro-cesses or the operating system can reuse entries in the translation buffer for such pages of memory that are commonly referenced. To allow this, an "address space match" entry in the page table entry signals that the translation buffer content can be used when the address tag matches, even though the address space numbers do not necessarily match. When executing virtual machine, on this CPU, with a virtual machine monitor, the address space match feature is employed among processes of a virtual machine, but an additional entry is provided to disable the address space match feature for all address space numbers for the virtual machine monitor.

Title: Autotransfusion system with portable detachable vacuum source
Inventor: OLSON DANIEL H
IPC: A61M27/00
Filed: 1993-03-17
Abstract: An autotransfusion system including a rigid receptacle carrying a blood collection bag internally and a manually operable portable vacuum source (MOPVS) also carried by the rigid receptacle. The system may be configured in a blood collection mode wherein the MOPVS is in flow communication with the interstitial space between the collection bag and the rigid receptacle to cause a negative pressure therein to draw blood from the patient's wound. In a reinfusion mode, the MOPVS is disconnected from the rigid receptacle and is directly connected to the drain tube leading to the patient to drain unwanted fluid from the patient's wound.      The rigid receptacle is inverted and connected to a transfusion line to reinfuse the blood collected within the blood collection bag. The interstitial space is vented to ambient pressure such that the blood within the collection bag is reinfused under force of gravity alone. A hydrophobic vent is connected to the flexible collection bag to vent air collected within the bag to the interstitial space.

Title: Process for the recovery of oil from waste oil sludges
Inventor: HEUER STEVEN R
IPC: C10G31/00
Filed: 1990-09-10
Abstract: Commercially valuable oil is recovered from refinery-produced, Resource Conservation and Recovery Act classified, hazardous waste oil sludges by a series of volatilizing and condensing steps (which may vary depending on the oil, water, and solids content of the sludge) resulting in the production of nonhazardous water and solid waste by products. A pumpable, low viscosity, high oil-and/or water-contentsludge (10) is first centrifuged (14) to separate free oil and water (16), while the thick waste oil sludge, centrifuge solids, or other sludges low in oil and/or water content are heated in a volatizer (24) to volatilize the contained water and oil. Dry, friable, deoiled solids are recycled with the oily sludge feed to prevent material agglomeration and heat exchanger fouling. Oil and water vapor from the high-temperature volatilization apparatus is recycled as an indirect heat source to the low-temperature volatilization apparatus. The volatilized oil and water are condensed and combined with the oil and water centrate, and the oil and water are essentially separated as by gravity in a settler. The separated oil is again centrifuged to remove any entrained water and solids. The nearly oil free, nonhazardous waste water and nonhazardous, deoiled solids can be disposed of in a conventional manner, and the commercially valuable recovered oil is suitable for further refinery processing.
