Title: Improved particle treatment in a toroidal bed reactor
Inventor: DODSON CHRISTOPHER E
IPC: B01J8/24
Filed: 1998-09-18
Abstract: In a process for processing particulate material with a stream of fluid in an annular processing zone, which includes the steps of supplying the particulate material for processing in the zone, discharging processed material from the zone and generating in the zone a circumferentially directed flow of fluid to develop a circulating turbulent band of particles, an improvement to the processing zone which provides a predictable particle flow path both circumferentially and helically of the zone.

Title: Variable attenuation type optical power attenuator with latching ratchet
Inventor: TAKAHASHI MITSUO
IPC: G02B6/26
Filed: 1999-03-10
Abstract: A variable attenuation type optical power attenuator permits easier adjustment of the amount of optical attenuation and it is able to securely maintained an adjusted or set amount of attenuation. The variable attenuation type optical power attenuator employs a fixed ferrule and a rotating ferrule that have their end surfaces polished, together with the central optical fibers thereof, to be formed into inclined end surfaces.      An alignment sleeve supports the fixed and rotating ferrules with optical fibers so that the distal ends thereof are opposed and that the ferrules may be relatively rotated, thus making up an assembly composed of a pair of ferrules. The assembly of the paired ferrules is supported in a rotating housing by a fixed housing.      The variable attenuation type optical power attenuator adjusts the distance between the optical fiber end of the fixed ferrule and that of the rotating ferrule by rotating the rotating housing to change the relative rotational angle in relation to the fixed housing. The new rotational angle thus obtained is maintained by the engagement between the face ratchet of a ratchet ring provided on the fixed housing and the face ratchet of the rotating housing.

IPC: H02P27/02
Filed: 1997-10-07
Abstract: This invention concerns a three-phase current regulator with interrupt-performed phase control characterized by a simple, cost-effective design, particularly by the use of a simple microcontroller (1) with only one or two interrupt inputs. This is made possible by forming zero crossover signals (U0A, U0B, U0C) the edges of which can be used for interrupt control. Interrupt routines in the program of the microcontroller (1) control the times for output of firing signals (ZA, ZB, ZC) starting exclusively from the zero crossovers as data about the three-phase network.

Filed: 1997-10-17
Abstract: First heat-transfer plates S1 and second heat-transfer plates S2 are radially arranged between a larger diameter cylindrical-shaped outer casing 6 and a smaller diameter cylindrical-shaped inner casing 7 to form combustion gas passages 4 and air passages 5 alternately in a circumferential direction, and a multiplicity of projections 22, 23 formed on both surfaces of the first heat-transfer plates S1 and second heat-transfer plates S2 are jointed to one another at tip ends thereof. Pitches P between adjacent projections 22, 23 are changed in a radial direction to make the number of heat transfer units substantially constant in a radial direction to uniformize temperature distributions on the first heat-transfer plates S1 and second heat-transfer plates S2 in the radial direction, thereby avoiding a decrease in heat exchanging efficiency and generation of unwanted thermal stress.

Abstract: A contact guide member extends transversely to the contact fingers on the contact carrier of electrical switching apparatus and has spaced openings through which the contact fingers extend and are held in spaced relation.   The contact finger guide member is positioned to isolate the arc toes adjacent the free ends of the contact fingers from the main contacts and the contact springs in order to protect the latter items from the arc gases and debris generated during arcing. The openings in the contact finger guide member are elongated to permit differentially pivoting of the contact fingers, but not axial movement. The contact finger guide member slides in a pocket molded in the end face of the contact carrier and is captured by and moves with the contact fingers.

Abstract: L'invention concerne des résonateurs au silicium, thermiquement insensibles, obtenus par micro-usinage, et dotés d'une précision équivalente ou supérieure à celle des résonateurs à quartz, ces résonateurs étant fabriqués par un procédé micromécanique de silicium sur verre. Dans un mode de réalisation, ce résonateur est réalisé à l'aide d'un gyroscope à diapason (4). L'utilisation des résonateurs au silicium permet d'obtenir des références de tension de précision (PVR), résistantes aux radiations. La sensibilité thermique est réduite par rapport à celle d'un oscillateur formé par un procédé de silicium sur silicium, et elle est comparable à celle d'un oscillateur à quartz. En utilisant un dispositif micromécanique basé sur un gyroscope à dispason (4), on obtient des résonateurs à partir d'un axe ou des deux axes de direction et d'entraînement du gyroscope. Un résonateur formé comme une boucle de résonateur (8) dont la fréquence de résonance est comparée à un étalon de fréquence produit une tension de polarisation comme tension de référence (Vref).
