Title: Gps-based traffic control preemption system
Inventor: HALL TIMOTHY J
IPC: G01C21/26
Filed: 1995-01-04
Abstract: A traffic control preemption system uses data received from a network of global position-ing satellites (GPS) to determine whether a ve-hicle issuing a preemption request is within the intersections allowed approach corridor. GPS signals are received and processed by the vehi-cle module to generate vehicle data including position, heading and velocity. The processed vehicle data and a preemption request are trans-mitted via radio transmission to all intersection modules located at intersections within range of the radio signal transmitted by the vehicle module. The intersection modules then com-pare the received vehicle data with a prepro-grammed map of allowed approaches to the in tersection. If the vehicle data matches suffi-ciently the map of allowed approaches to that intersection, the vehicle's preemption request is forwarded to the intersection controller.

Title: Method and apparatus for the continuous production of cellulosic pulp
Inventor: HOFFMAN ROGER P
IPC: D21C7/00
Filed: 1995-08-31
Abstract: A method and apparatus for the continuous production of cellulosic pulp for use in a papermaking process. The apparatus includes a vessel (1) containing a pulping liquor and the vessel consists of a first impregnation zone (2) and a second attrition zone (3). Wood chips are continuously fed into the upper end of the first zone and are subject to gentle agitation to impregnate the chips with the liquor. The impregnated chips then flow into the second zone where they are heated to a low temperature below 125 ~C and subjected to more severe agitation to break down the chips and liberate the individual fibers. The liquid level in the first zone is higher than in the second zone, causing the liquid to flow upwardly in the second zone with the cooking liquor and the liberated fibers being continuously discharged from the upper end of the second zone, while larger wood chips are retained in the second zone for further attrition. The liberated fibers are removed from the cooking conditions as they are liberated to thereby prevent overcooking and discoloration of the pulp.

Title: A motor-driven system for steering a vehicle
Inventor: MIOTTO FRANCESCO
IPC: B62D5/04
Filed: 1995-12-14
Abstract: A motor-driven system for steering a vehicle is characterized in that the steering control device 1 (e.g. steering-wheel) and the steering device (3) (e.g. steering-box) are connected through a motorized device (2) suitable to transmit to the steering device (3) a movement having an amplitude different from the movement given to the control device (1) by the pilot, said change of amplitude being controlled by a control unit according to various parameters.  The pilot can thus steer with an effort comparable to the effort he would have made in the absence of the motorized device (2), but with a lower amplitude of the movement of the control device (1).  This allows the use of control devices characterizedby very small global movements, such as for example devices in the form of a cloche, a handlebar or a joystick, yet retaining a precision in the steering control comparable with the precision of conventional highly geared-down steering devices. The invention is particularly useful in all those steering manoeuvres which require large movements of the control device (1) (e.g. parking), and for allowing the steering with conventional steering-wheels to people with little functional capacity of the upper limbs, which may have sufficient strength in the hands and wrists to hold the steering-wheel but not enough strength in the shoulders to move the arms enough for rotating the steering-wheel beyond a small arc of rotation.

Abstract: La présente invention concerne un système synchrone (10) de bus bidirectionnels grande vitesse pour données numériques. Ce système comporte un bus sans fin de données M bits (14), un bus sans fin de signaux d'horloge à onde sinusoïdale stationnaire (12) et une pluralité d'interfaces intégrées (16a, ...) de circuits bus. Chaque interface de circuits intégrés bus (16a, ...), est de préférence sensiblement intégrée à un seul microcircuit LSI de type CMOS, et comporte un nombre M de pilotes de bus, chaque pilote étant associée à une logique de réception de données, un nombre M de récepteurs de données, chaque récepteur étant associé à une logique de réception de données, et enfin un récepteur de signaux d'horloge (19). Les intensités de sortie de tous les pilotes de bus (30) de chacun des microcircuits sont de préférence stabilisées de façon que chaque pilote utilise sensiblement la même tension de sortie pour faire fonctionner le bus (14). Ces pilotes sont de préférence des logiques CMOS à pilotage polaire complémentaire. Dans ce cas, pour chaque récepteur de données (20a - 20h), un circuit d'entretien de bus (44) est couplé à la sortie et à l'entrée du récepteur de bus de sorte que le maintien du bus de données soit maintenu à son dernier état. En outre, les récepteurs de signaux d'horloge (19) ainsi que les récepteurs de données (20a - 20h) se présentent sous forme de comparateurs haute vitesse (22) à hystérésis interne. Les récepteurs de signaux d'horloge (19) sont de préférence pourvus d'un temporisateur générant un délai de sécurité pendant lequel les pilotes de bus (30) passent par trois états avant de pouvoir piloter le bus de données, ce qui évite les conflits sur le bus et garantit échantillonnage final des données.
