Title: High resolution gamma ray detectors for positron emission tomography (pet) and single photon emission computed tomography (spect).
Inventor: FENYVES ERVIN J
IPC: G01T5/08
Filed: 1990-11-09
Abstract: A device and method for detecting gamma rays in a diagnostic imaging system preferably utilizing fast step index scintillating fibers and photomultipliers is provided by the present invention. A plurality of scintillating fibers are formed into layers comprising substantially parallel fibers positioned lengthwise each other in each layer. Each layer is positioned parallel each adjacent layer with each layer having its respective fibers at an angle of substantially either 60 DEG  or 90 DEG  to each adjacent layer. Preferably, position sensitive photomultipliers are provided and each photomultiplier is coupled to a plurality of fibers and each fiber has at least one end coupled to a photomultiplier. Data output from each photomultiplier is collected and processed to determine spatial coordinates of the origination position of a detected gamma ray. The present invention provides a high resolution gamma ray detector having an improved signal-to-noise ratio. This improves significantly the diagnostic power of the presently used PET and SPECT systems, and greatly extends the field of their application both in medical diagnosis and research. In addition, the present invention enables use of longer-lived positron emitting radioactive isotopes than presently used in typical PET systems.

Title: Method and device for solid phase microextraction and desorption.
Inventor: PAWLISZYN JANUSZ B
IPC: G01N30/18
Filed: 1991-04-02
Abstract: A device for carrying out solid phase microextraction is a fiber (6) contained in a syringe (4). The fiber can be solid or hollow. The syringe has a barrel (8) and a plunger (10) slidable within the barrel, the plunger having a handle (12) extending from one end of the barrel. A hollow needle (18) extends from an end (16) of the barrel opposite to the plunger. The fiber is contained in the needle. When the plunger is depressed, the fiber extends beyond a free end (28) of the needle and when the plunger is in a withdrawn position, the fiber is located within the needle. The syringe protects the fiber from damage. When it is desired to analyze a sample in a bottle having a septum, the needle is inserted through the septum and the plunger is depressed so that the fiber will extend into the sample. After one or two minutes, the plunger is moved to the withdrawn position so that the fiber will return to the needle and the syringe is withdrawn from the sample bottle. The syringe is then inserted through a septum in a gas injection port of a gas chromatograph. The plunger is again depressed so that the fiber will extend into the gas chromatograph and an analysis of the components on the fiber is carried out. Then, the plunger is moved to the withdrawn and the syringe is withdrawn from the injection port. Previously, samples were analyzed using liquid-liquid extraction or using cartridges. Both of these methods are relatively expensive and time consuming. Both of these methods also require the use of solvents which can be difficult and expenssive to dispose of.

Abstract: L'invention concerne un procédé de réglage à deux positions du lambda d'un moteur à combustion interne équipé d'un catalyseur, caractérisé en ce que le réglage est effectué de telle manière que les variations du réglage présentent, au moins dans des régimes déterminés, une amplitude maximum, mais limitée à une valeur telle qu'elle n'entraîne pas une irrégularité de fonctionnement du moteur à combustion interne et que le taux de conversion moyen du catalyseur reste inférieur, dans une proportion déterminée, au taux de conversion susceptible d'être atteint avec une amplitude réduite dans le cas d'un régime stationnaire du moteur à combustion interne. Ce procédé vise non seulement à une amplitude de réglage minimale comme dans les procédés classiques de réglage à deux positions du lambda, mais de plus, en fonction du taux de conversion du catalyseur, l'amplitude est toujours réglée à une valeur telle qu'en régime stationnaire elle soit trop élevée pour obtenir une conversion optimale, mais qu'elle se traduise par un réglage rapide et donc par une émission minimum de gaz nocifs relativement à la somme de tous les états stationnaires et instationnaires.

Abstract: Procédé et appareil de stimulation transcutanée du coeur à l'aide de stimuli de stimulation composés chacun d'une série d'impulsions individuelles. Le coeur réagit à la série d'impulsions comme si la série était une seule impulsion continue, tandis que la série d'impulsions produit des réactions des muscles squelettiques similaires à celles que l'on attendrait d'impulsions individuelles. Il en résulte une réduction de la stimulation des muscles squelettiques et des nerfs, et moins de gêne pour le patient. Une nouvelle réduction de la stimulation des muscles squelettiques et des nerfs peut être obtenue en émettant une série d'impulsions initiales d'amplitude inférieure au seuil de stimulation des muscles squelettiques dans chaque stimulus de stimulation et en émettant des stimuli de fond qui surviennent dans les intervalles entre les stimuli de stimulation. Ledit appareil comporte un circuit de minutage et de commande (20) et un circuit générateur de stimuli (30) connecté à des électrodes (70, 72).

Abstract: For a three-phase power supply having star-connected primary windings (1-3) which are in each case connected to a phase conductor R, Y, B of a three-phase system and, from the star point, to the neutral conductor (N) of the three-phase system, in the event of an earth short of a phase conductor, there is a high current flow through the primary windings (1-3) and the neutral conductor N. In order to avoid such saturation-dependent overloads of the three-phase power supply, until now, a relay switching contact has been inserted, as part of a costly earth-short monitoring unit, into the link between the power supply star point and the neutral conductor N of the three-phase system, which unit is replaced, according to the invention, by a current-limiting power source (4). As a result of its simplicity and reliability, such a power supply is particularly suitable for use in the case of electrical energy consumption meters. <IMAGE>

Abstract: In constrast to ring spinning, pot spinning necessitates a further rewinding operation for the final yarn formation. Whereas, in ring spinning, spinning is already carried out onto a yarn carrier, in pot spinning first only a yarn carrier has to be introduced into the pot, in order to attach the spinning cake as a yarn roll onto the yarn carrier. The feed of the yarn carriers to the spinning stations and their exact positioning necessitate a high outlay in handling terms. 
<??>By means of the invention, the feed of the yarn carriers is simplified and is integrated into the flow of the spinning operation. For this, the spinning pot (8a, 8b, 8c, 8d) is mounted displaceably in its longitudinal direction. In the upper end position of the spinning pot, the exit orifice (23a, 23b, 23c, 23d) of the yarn guide (6a, 6b, 6c, 6d) is level with the lower edge (24a, 24b, 24c, 24d) of the spinning pot, and in this position of the spinning pot vertically arranged yarn carriers (32a, 32b, 32c, 32d) for the rewinding of the spinning cake (26a, 26b, 26c, 26d) can be transported forwards and away by means of a horizontally arranged transport device (27). Futhermore, the spinning pot can be driven in order to generate the lifting movements (11) for the spinning operation.

Abstract: Apparatus and method for a directional drilling system is disclosed wherein a concrete pit is poured at a reference entry angle in the earth so that a drilling platform cartridge inserted into the concrete pit is set at the desired entry angle. A frame ,including elongated guide ways extending between ends of the platform cartridge, guides a carriage that advances a drill string through the earth at the reference angle. Preferably, a drilling head at the end of the drill sting and the remainder of the drill string are rotated by a drive motor carried on the carriage. A drill bit and drill bit motor are mounted coaxially and eccentric with respect to the drilling head. The center axis of the drill bit and drill bit motor, and the center axis of the rotating drilling head are offset and define a known relationship. The offset relationship between the center axis of the drill bit and drilling head defines an eccentric position in which the drill bit overcuts relative to the outside diameter of the drilling head in an eccentric position. As long as the drilling bit and drilling head rotate simultaneously, movement of the drill string is controlled generally in a straight line. If rotation of the drilling head is stopped, the drill string is steered in the direction of the eccentric position of the drill bit since there is no clearance on the opposing side of the drilling head. With the drill bit and drill string continuously rotating, a slight overcut of approximately one-half inch occurs in the bore. A guidance system for measuring the position of the drilling head is provided by a single axis angular rate sensor which rotates with the drilling head to generate horizontal and vertical angular rates which are integrated to provide the horizontal and vertical position angles of the drilling head as it rotates through the predetermined quadrants over which the angular rates are integrated. An encoded gravity referenced disk is utilized to measure the quadrant positions of the rotating sensor and the eccentric position of the drill bit. An accelerometer is utilized to measure the distance travelled from the drilling platform. By multiplying the distance travelled by the horizontal and vertical position angles, the position of the drilling head is known and deviations from the desired drill direction can be determined. The drilling head can be steered in a desired direction to eliminate the deviation by stopping rotation of the drilling head. Upon eliminating the deviations, simultaneous rotation of the drilling head and drill bit again commence to drill in a straight line.
