Abstract: An apparatus is disclosed for use in a drill string 10 to prevent separation of a lower tubular member 16 from an upper tubular member 15 by a rotational force applied from a down-hole motor 22. The down-hole motor 22 is rotated by drilling fluid pumped from the surface, through a passage formed within the drill string 10, and into the down-hole motor 22. A valve 36 is positioned in the passage in the drill string 10 and has a first operating position adapted for passing the drilling fluid to the down-hole motor 22, and a second operating position adapted for substantially blocking the drilling fluid from being delivered through the down-hole motor 22. The valve is of a two piece construction, having a first body 44 connected to an upper tubular section 14 and a second body 46 connected to the down-hole motor 22. Thus, longitudinal movement between the upper tubular section 14 and the down-hole motor 22, which is a result of rotation of the lower tubular section 16 by the motor 22, causes corresponding longitudinal movement of the first and second bodies 44, 46 between the first and second operating positions. <IMAGE>

Abstract: A fiber optic measuring device can be used, for example, as a rate gyro. Variation in a measured parameters engenders a phase difference between two waves. The measuring device includes a light source 1, a SAGNAC ring interferometer 2, a detector 3, a phase modulator 4, and a electronic unit 7. The electronic unit 7 includes a processing system 9 which furnishes a signal that is a function of the measured parameter and an electronic sub-unit 12 for controlling the phase modulator 4. The control signal for the modulator is a superposition of a first, periodic gating, bias signal  PHI b(t) with period 2 tau and amplitude  PHI bm, and of a second, staircase, negative-feedback signal  PHI m(t) synchronized with  PHI b(t), each step of which has a duration equal to  tau  or to one of its sub-multiples, and an amplitude  PHI s, which is a function of the value of the measured parameter and which falls back to zero when its amplitude exceeds a predetermined value  PHI mm .  PHI bm and  PHI mm are slaved to 2 PHI bm+ PHI mm=2n pi  (where n is an integer). The response to the singular phase shift introduced during the fall-back of the negative-feedback signal is for this slaving and hence is used to keep the gain of the modulation chain constant.

Abstract: The centrifugal fertiliser spreader has several counter rotating bladed impeller discs on vertical axes. It deflects the fertiliser particles, projected in a forward direction (125) beyond the front (119) of the storage hopper (101) into one (126), which does not extend in front of it. Thus the distance (W), for which particles are projected at right angles to the travel direction (111), remains nearly constant. constant. The deflection pref. takes place to either side.

Abstract: A shared-buffer-memory-based ATM switching module (1) used with ATM cells having a multiplicity of priorities has a plurality of queues for each output port (O-N), one for each cell priority, and handles buffer overflow in a manner fair to all output ports. It initially allows output-port queues to completely consume the buffer memory (12). Thereafter, when an additional incoming cell (on 7) is received for which there is no room in the buffer memory, the lengths of all of the queues of each output port are individually summed and compared to determine which port has the greatest number of buffered cells. A buffered ATM cell is discarded from the lowest-priority non-empty queue of that port. The incoming cell is then stored in the memory space vacated by the discarded cell. <IMAGE>

Abstract: A dental model and articulation system are disclosed. The dental model comprises cast mold material formed around an elongate pin or rod. A longitudinal, tapered pin or rod is embedded in the model during pouring of the casting material. The pin or rod extends longitudinally through the base of the model beneath the teeth impressions of the model. The longitudinal axis of the pin or rod lies in general parallel alignment with the line of teeth in the model. The pin or rod can be removed from the model, and the model can be cut into several sections or dies. These sections or dies can then be reassembled back on the pin or rod in the precise, true relationship that existed in the model prior to the model being cut into sections. The extending ends of the pins or rods can be removably attached to a flexible member such that models of the upper teeth and lower teeth of a person's jaws can be moved in lateral or protrusive movement and back to centric occlusion.

Abstract: On peut augmenter considérablement le taux de production de fibres creuses microporeuses symétriques de haute qualité en procédant à une sélection des matières premières, de l'équipement et des conditions de traitement. La sélection de concentrés polymères, de solutions précipitantes et des dimensions des buses à filer les fibres est particulièrement importante pour permettre d'obtenir des vitesses de production supérieures à 30 mètres par minute. Dans le procédé décrit, une solution à filer polymère (12) est filtrée à travers un filtre-presse (16) et acheminée dans un appareil à filière de filage au mouillé à jet sec (20) conjointement avec une solution précipitante (22). Ces deux solutions (12, 22) sont filées depuis l'appareil à filière (20) pour former une fibre creuse, laquelle est alors rapidement refroidie et enroulée sur une bobine enrouleuse (40). Le produit obtenu grâce audit procédé est une fibre de haute qualité qui peut être utilisée dans toute une gamme d'usages médicaux telles que dialyse rénale, filtrage sanguin, etc.

Abstract: A process for forming a protective barrier on metallic or wood surfaces to provide protection against abrasion, corrosion, heat, and fire. The process is begun by first forming a fixed surface on the metallic or wood article. On metallic articles, the fixed surface is formed by cleaning the surface and then exposing the surface to concentrated phosphoric acid. On wood, the fixed surface is formed by thoroughly cleaning the surface with hot water and detergent only. After the fixed surface is prepared, it is then exposed to a 10-16% silicate salt for at least one minute and then allowed to dry completely at 305 degrees Fahrenheit to form a first layer of silicate salt over the fixed surface. During the drying process, a portion of the sodium silicate is converted into silicon dioxide. A plurality of sodium silicate layers are then formed over the first layer of sodium silicate. After the last layer of sodium silicate is formed, it is then exposed to concentrated phosphoric acid to form a bi-layer thereon comprised of an inner layer of sodium silicate and an outer layer of silicon dioxide. In an alternative method, each sodium silicate layer is exposed to concentrated phosphoric acid to create a plurality of bi-layers over the fixed surface.

Abstract: In motors or the like, for example, the arc, especially commutator sparking, and/or a replacement criterion is detected at the connecting terminals and evaluated with reference to predetermined characteristics. According to the invention, either the motor current is measured and the high-frequency component generated by commutator sparking is evaluated from that or the high-frequency components are decoupled at the connection terminals of the electric motor and capacitatively short-circuited. Alternatively, high-frequency stray currents flowing from the connection terminals to the casing can be detected and capacitatively short-circuited. The individual measuring arrangements therefore essentially comprise an h.f. current transformer (10), the signal from which is taken to an evaluating instrument (12, 22, 32).
