    Abstract: An arrangement for detecting metallic particles carried by a fluid includes an elongated single turn coil (12) which surrounds an elongated passage (11) through which the fluid flows and has a length as considered in the longitudinal direction of the passage (11) that is at least equal to the diameter of the coil (12). Two longitudinally extending portions (13, 14) of the coil (12) delimit a gap (15) which extends along the passage (11) and completely physically separates the portions (13, 14). At least one capacitor (16) is arranged directly at the gap (15) and is electrically connected between the portions (13, 14) to form an electronic resonator circuit with the coil (12). The resonator circuit (12, 16) is driven at all times at its resonant frequency as influenced by the presence of metallic particles in the passage (11) and the operating temperature. The inductance to capacitance ratio of the resonator circuit (15, 16) has the value of at most one to four.

    Abstract: The present invention is related to a sight glass (10) that utilizes both reflected light at a glass to air interface (40) as well as the light transmitted through a glass to fluid to glass interface (44) to form a light pattern that is indicative of the true fluid level. By requiring that light always appear in either an ''air'' or ''fluid'' channel (42, 46), any absence of light is assumed due to film coated surfaces or to other abnormal conditions. An absence of light is a signal that maintenance is required.

    Abstract: An array of optical fibers (28) is precisely positioned in spaced apart channels (29) in a head (22) when a metal, such as tin-lead solder, is used to fix the fibers in the channel. A glass fiber (38, 40) is first ion plated with about 1 x 10-6 m of a metal (52) such as nickel which is wetted by the solder. The fiber (70) is then placed loosely in a channel (80) in a metal holder (82) and solder (84) is infiltrated to surround and adhere to the fiber. Strain on the glass fiber where it exits its holder channel (50) is alleviated when the polymer jacket (74) is also ion plated with metal (72) and is bonded to the holder by solder (84).

    Abstract: A short-circuited loop of conductor comprises an electromagnetic short-circuit hoop probe (10, 32, 44, 54) which is electrically insulated from a gas stream (25) passing therethrough either by spatial isolation (Figure 2) or by a coating of electrical insulation (Figures 3-5), whereby to reduce noise and DC current levels which could otherwise pollute signals of interest therein. A large hoop version of the noncontact probe (10) permits electrostatic diagnostics of gas streams downstream of flame (Figure 2).

    Abstract: A process for adhering small metal fibers (24), to a surface (23) by plasma spraying the fibers on a workpiece (20), and articles made using the process. The process is especially useful for improving the strength of plasma arc coatings, as well as for improving the bonding of plasma arc coatings to substrates. To make an improved ceramic faced metal article, fibers (24) are sprayed onto the workpiece (20, 34) by injecting fibers (44) into the plasma stream (36) external to the plasma gun nozzle (38). Then, plasma sprayed ceramic particles are caused to surround the fibers as a matrix (26). The optional interposition of a removable polymer material (3) on the workpiece surface (23), after the fibers (24) are sprayed but before the ceramic matrix (26') is sprayed, provides an effective way of providing a low stiffness connector (30') between a low thermal expansion coefficient ceramic material (26') and a high expansion coefficient metal substrate (20'). The connector alleviates strains from thermal expansion differences.

    Abstract: Réglage automatique de la distance de recul dans une machine EDM (d'usinage par décharge électrique) pour maintenir une distance de recul ou retrait de contact entre la pièce à usiner et l'électrode d'usinage indépendamment de l'usure de l'électrode et de la profondeur percée. Un commutateur de fin de course (20) arrête le mouvement de retrait vers le haut du bélier (10) lorsque le dispositif d'actionnement (22) du bélier entre en contact avec le commutateur de fin de course (20). Des électrodes (14) sont portées par le bélier (10) et lorsqu'un mauvais fonctionnement de la machine se produit, le bélier (10) est rétracté vers une position limite déterminée par la position du dispositif d'actionnement (22) par rapport au commutateur de fin de course (20). Le dispositif d'actionnement (22) est maintenu magnétiquement sur le bélier (10) et se déplace vers le haut vers le commutateur de fin de course (20) lorsque le mouvement descendant du bélier (10), pendant l'usinage, provoque le déplacement du dispositif d'actionnement (22) et le fait entrer en contact avec des écrous (32) qui sont stationnaires par rapport au bélier (10). De ce fait, la position du dispositif d'actionnement (22) varie selon la profondeur d'usinage et se traduit par une distance de recul constante.

    Abstract: A bypass valve (12, 14, 214) for use with a componet of an air cycle machine (10) is disclosed, wherein the component includes a conditioning member, an inlet and an outlet. The air cycle machine (10) includes a component housing portion (22). The component housing portion defines a first volume and includes a port for receiving the valve. The valve comprises a housing for mating with the port, an air entrance opening adapted to be positioned adjacent the inlet, an air exit opening adapted to be positioned adjacent the outlet, and a valve portion for controlling at least one of temperature and pressure of the air at the outlet. Control is accomplished by permitting air flow from the entrance opening to the exit opening and bypassing the conditioning member and by prohibiting air flow from the entrance opening to the exit opening for directing substantially all of the air into the conditioning member. The valve portion is substantially entirely positioned inside of the first volume in the port. An air cycle system using the bypass valve is also disclosed.

    Abstract: A gas feed system for detonation gun apparatus (2) having a labyrinth shaped gas path. The labyrinth (30) is positioned between the fuel and oxygen supply and the combustion chamber (12) of a detonation gun. The labyrinth (30) allows the fuel and oxygen supply to flow into the combustion and precludes the migration of the detonation wave front into the fuel supply by destroying that portion of the detonation wave front that enters the labyrinth (30). The labyrinth gas feed system increases safety, reliability and productivity of the detonation coating process.
