Title: Rotary device with slidable vane supports
Inventor: SMITH JAMES E
IPC: F01C21/08
Filed: 1995-12-28
Granted: 2000-08-22
Abstract: An axial vane rotary device (14) includes a stator (16) with a cylindrical internal chamber (34) defined by an annular outer wall (40) and two side walls (36, 38) of the stator. Each side wall has an annular cam surface (42, 44). A rotor (54) is rotatably mounted within the chamber. The rotor has an annular outer wall (66) and a plurality of angularly spaced-apart, axially extending slots (64) extending therethrough. A vane (68) is slidably received in each slot. The vanes reciprocate axially and alternatively expand and compress spaces between adjacent vanes and the cam surfaces as the rotor rotates. The cam surfaces have alternating first portions (92) and second portions (90). The second portions are further from the rotor than the first portions. The first portions of one said cam surface are aligned with second portions of another said cam surface. The slots extend radially outwards on the rotor to the annular outer wall thereof. The outer edge of each vane slidably engages the annular outer wall of the stator. Each vane has an enlarged outer portion (75) slidably received in an enlarged outer portion (65) of one said slot (64).

Patent CA-2219773-C (CA)
Inventor: SNIDER REX RICHARD
IPC: F28D19/04
Filed: 1996-03-25
Granted: 2001-03-27
Abstract: In an air preheater with a large lower cold end center section and a smaller, upper hot end center section, the connecting plate duct assemblies on both the hot and cold end are made the same height rather than to have cold end connecting plate duct assemblies which are larger and equal in height to the cold end center section. This minimizes the design and manufacturing costs and provides cold end connecting plate duct assemblies which are smaller, lighter and easier to handle. This then requires that the housing panels around the outside of the rotor be longer to reach between these connecting plate duct assemblies. At the ends of the hot and cold center sections are main support pedestal panels which support the hot end center section above the cold end center section. These main support pedestal panels together with the housing panels complete the rotor housing. In order to compensate for the difference in the height of the cold end center section and the hot end center section and the resulting difference in the distance between the hot and cold center section and between the hot and cold connecting plate duct assemblies, the main support pedestal panels include offsets which extend downwardly along the sides of the cold end center section to meet with the cold end connecting plate duct assemblies.

Patent CA-2235901-C (CA)
Inventor: SPRITZER MICHAEL H
IPC: C02F1/72
Filed: 1998-05-26
Granted: 2004-04-27
Abstract: A system and method for treatment of a feed material includes a reactor chamber in a reactor vessel. The reactor vessel has a longitudinal axis which is vertically oriented so that gravitational forces act generally in a direction along the axis between a top and a bottom of the vessel. A feed material is introduced by a nozzle into the reactor chamber as a jet stream through the top end of the vessel. This jet stream causes back-mixing in the reactor chamber, contributing to rapid initiation of reaction and general down flow of material through the reactor chamber. The material in the reactor chamber can be quenched to dissolve sticky solids in the effluent before the effluent is discharged from the lower end of the vessel. Further, the reactor vessel can include a plug flow section to carry out additional reaction of the feed material.

Granted: 2003-07-08
Abstract: A particulate receiving and dispensing container having a vessel and a cooperating closure is provided. The vessel has a generally circular mouth with a segmental discontinuity therein.  The vessel mouth is slidably engagable with a grater.  Specifically, with the cylindrical housing end portions of a grater drum when so engaged, the segmental discontinuity is preferably located alongside portions of a hopper housing that are integral with end adjacent to the grater drum housing. After being charged with particulates from the grater, the vessel is separated from the grater and the vessel mouth is associated with a valve equipped closure which cooperates with the segmental discontinuity.  Thus, an operating tab for opening and closing the closure valve moves in a depression in the closure.  The depression in the closure fits into and over the segmented discontinuity.

Abstract: The present invention relates to light guides (1) capable of encoding the transverse and longitudinal coordinates of light emission induced by the interaction of photons in an array of a plurality of the light guides. Each light guide has at least two discrete crystal segments (4) adjacently dispos ed along a common longitudinal axis of the light guide (1). Between adjacent segments is a boundary layer (7) having less light transmission than the light transmission of the crystal segments (4). A light absorbing mask (8) increases light adsorption in a segment (4). Photons enter the light guide ( 1) and cause the emission of scintillation light which is delivered in differen t and resolvable quantities to light sensing devices. The differences in quantity of delivered light is caused by successive decreases in light transmission t o light transmitting end (5) caused at least in part by the boundary layers (7 ). The differences in quantity of light establish the segment from which the light emission took place.

Granted: 2006-02-21
Abstract: A method of measuring a body region of a human body includes recording at least two images of the body region from different camera positions, from which the contour lines are ascertained, for example, as a contrast. Used for scaling the images is a reference object with a reference zone, to which the camera is set in a perpendicular or near perpendicular viewing direction by means of an angle-determining device. The reference zone can be defined, for example, by perpendicularly protruding fins. From the projected images of the contour line and the reference zone, an individual model of the outside surface of the body region is subsequently ascertained by means of the reference model.      From this individual model a prosthesis or orthesis can be fabricated.
