Abstract: Titre: MOTEUR ELECTRIQUE A DOUBLE PULSIONS: Le système moteur à fonctionnement électrique décris ici comporte un nouveau principe encore à ma connaissance jamais appliqué depuis l'utilisation des moteurs électriques. Il comporte que le rotor entre en rotation, mais aussi que le stator entre de plus en rotation mais dans le sens contraire. Ce système moteur pourra donc avoir un nombre de rotation supérieur de deux fols aux moteurs normaux. Le rotor entraînera une unité motrice, et le stator entraînera aussi une autre unité motrice. Le système moteur à double pulsions pourra fonctionner avec du courant électrique direct ou alternatif, avec aimants permanents ou électro-aimants, dépendamment des propriétés recherchés par le système moteur, et devra permettre d'avoir le contrôle sur les courants induits à l'extérieur de l'enceinte des échanges électromagnétiques. (voir figure 1) La conception des pièces du moteur permettra (en grossissant les unités électromagnétiques) et les diamètres des pièces motrices, de fonctionner avec de très petites puissances à de très grosses puissances. (de l'ordre de .1 cheval vapeur à 10000 chevaux vapeurs. Ce système moteur devra faire fonctionner deux charges mécaniques exigeant des forces similaires. Si l'on cesse la rotation de l'une des parties motrices, alors on ne retrouvera qu'un simple moteur normal, ayant la puissance amoindrie du même coup. page 1

Title: Apparatus for sealing around members extending there-through
Inventor: HILAL SAID S
IPC: A61B17/00
Filed: 1990-10-30
Abstract: IMPROVED APPARATUS FOR SEALING AROUND MEMBERS                EXTENDING THERETHROUGH     Abstract An apparatus is provided for sealing around shafts or tubes of varying diameter. Its basic element comprises an elastomeric sealing body with an axial passage which is radially compressed from more than two sides to compress the passage into sealing engagement with a member extending through the passage.  Radial compression is achieved by cams and followers disposed around the body which cooperate with angularly spaced radially extending lugs formed integrally with the body.  The cams are spring biased to normally compress the axial passage of the sealing body.  Levers operable by one hand of the user are provided to selectively release the apparatus.

Title: Dynamic data storage system
Inventor: RYU TADAMITSU
IPC: G06F12/00
Filed: 1991-03-11
Abstract: ABSTRACT OF THE DISCLOSURE DYNAMIC DATA STORAGE SYSTEM           The system of the present invention provides a data storage system program 18 between a user and physical memory device 14 which stores file records 20.  The data storage system 18 stores records as linked record segments 40/50 that can be randomly located within the memory storage device 14.  The segments 40/50 are linked by a next segment address found in a next segment address field 50/51 of a record segment 40/50.  When a record needs to be expanded and the current record segment 1000 is not large enough to accommodate the expansion, another record segment 1082 is allocated and used. If variable length record segments 40 are used, only a single record extension is required.  However, if fixed length record segments 50 are used, the system allocates sufficient fixed length record segments to store the additional data.  When records shrink in size or are deleted, the vacant space becomes available for reuse and the system attempts to remove the vacant space by combining record segments and storing a single segment in available vacant space.

Title: Method for cement evaluation using acoustical logs
Inventor: RUTLEDGE JOHN M
IPC: E21B47/00
Filed: 1991-06-18
Abstract: ABSTRACT OF THE DISCLOSURE            An improved method to determine the quality of a material disposed in an annular space behind a casing (or a liner) in a wellbore.  A transit time of a sound wave to travel through a specimen of the material is determined, and a pulse velocity is calculated. The slurry density and mixing rate of the material are determined at a wellsite, and the slurry volume can then be calculated by multiplying the amount of time that the slurry remains at the slurry density by the mixing rate.  The slurry has a theoretical acoustical impedance that is equal to the slurry density multiplied by the pulse velocity.  The true annular displacement volume and a theoretical acoustical impedance map, an attenuation rate map, and a voltage map are then drawn.  After running an acoustical log, a calculated acoustical impedance is derived, and is compared to the theoretical acoustical impedance to determine the quality of the material.

Title: Real-time decentralized network traffic management using a parallel algorithm
Inventor: GERSHT ALEXANDER
IPC: H04M3/36
Filed: 1991-11-26
Abstract: REAL-TIME DECENTRALIZED NETWORK TRAFFIC MANAGEMENT        USING A PARALLEL ALGORITHM            ABSTRACT     A decentralized, state dependent access-control and routing strategy for real-time control of circuit switched networks.  To decentralize the traffic control tasks, we partition the network into subnets and assign a specific traffic controller to each one.  The traffic controllers obtain periodic (approximately every 5 minutes) subnet measurements and compute the optimal traffic control policy of the subnet through an iterative and parallel dialog with the other controllers.   Each controller implements the new control policy within its subnet until the next measurement epoch, thereby allowing decentralized call handling.   In the formulation of the joint access-control and routing problem,  we allocate the incoming demand (for a given period),  the optimal strategy to maximize the predicted minimum (over all network Trunk Groups) Trunk Group residual capacity.  Secondly, when the projected demand can not be accommodated through this strategy, the optimal strategy rejects the extra demand at source,  in an "equitable"  manner.   The mathematical formulation of the  above  routing  and access-control objectives leads to an Equilibrium Programming Problem (EPP).  The EPP formulation is decomposed into a number of subproblems  and  solved--in  parallel--by  the  inter-communicating subnet  controllers,  thereby  satisfying real-time control  requirements.   The ensemble of the subproblem solutions forms the network-wide (globally) optimal traffic management strategy for the upcoming period.

Abstract: ABSTRACT            In many water sports in which the athlete uses the arms and hands to generate most of the propulsion, a utility device, equivalent to the diver's flippers, to help him get more push from his strokes is not commonly used. In this invention, the space between the fingers of a glove is filled in with webbings made of flexible but relatively impermeable material. The webbings increase the surface area a spread hand presents to the water and give the user a bigger push from his stroke.

Filed: 1992-01-16
Abstract: A motor (10) comprises a stator (14) having an associated stator winding (24) formed of a conventional material such as copper, or of a superconductive material.  A rotor (12) for the motor is also formed of a superconductive material.  The rotor is placed in a cryostat (16) and cooled from a first temperature which is above a critical level to a second temperature which is below the level.  The stator is placed in a second and separate cryostat (18) and the stator winding is energized while the the rotor temperature is being lowered to below the critical level.  Once the superconductive material of the rotor has been cooled to a level below the critical level, the stator winding is de-energized.  Currents are now induced in the superconductive material of the rotor to trap or maintain magnetic flux therein.  Thereafter, the rotor acts as a permanent magnet so long as it is maintained below the critical temperature.

Title: Emergency elevator governor actuator
Inventor: SHERIDAN WILLIAM G
IPC: B66B5/02
Filed: 1992-01-17
Abstract: ABSTRACT OF THE DISCLOSURE      This invention relates to a system for tripping the governor rope safety blocks in the event the car motion while the car doors are open, so that the governor rope will set the emergency brakes on the car or counterweight. Governors for both the car and counterweight can be fitted with the system of this invention.  The system includes a solenoid which acts on the tripping crank of the standard governor rope safety blocks.  The solenoid is connected to the elevator controller and is normally inoperable to affect operation of the governor rope blocks.  When the controller senses motion of the car while the car doors are open, a signal is sent to the solenoid and it acts directly on the safety block tripping crank so that the safety blocks are brought to bear against the governor rope whereby the emergency brakes on the car or counterweight, or both, are set to stop car and/or counterweight movement in the hoistway.
