Title: Visual display system for producing a continuous virtual image
Inventor: AMERY JOHN G
IPC: G02B27/18
Filed: 1999-10-27
Granted: 2008-01-08
Abstract: A visual display system for producing a continuous far-focused virtual image according to the present invention includes a number of adjacent video image generation and display modules. Each module includes an image generator that generates a video image representative of a portion of a composite display image displayed on a video display. The visual display system also includes a number of optical viewing lenses associated with each video image generation and display modules and positioned between the operator and the video display. The lenses restrict the operator's field of view such that the operator views only a portion of the active display area of the video displays. The lenses of adjacent modules are joined together along their edges to form an enclosure partially surrounding the operator so that the operator views the composite display image displayed on the video displays through the lenses and perceives the composite display image as a continuous far- focused virtual image.

Title: Process and apparatus for a mixture resolution
Inventor: CHARZAT CLAUDE
IPC: B01D11/02
Filed: 1997-04-07
Granted: 2006-10-10
Abstract: Disclosed is a process for the resolution of a mixture into at least one first fraction and one second fraction, the respective compositions of said fractions differing by at least one element. The process further comprises at least one elementary stage of fractionation, in which at least two inflows are placed in contact, these two flows being a first inflow (10) with low first fraction content, notably in counter-current, and a second inflow (11) with low second fraction content. Two outflows are obtained, said flows being a first outflow (12) enriched in first fraction with respect to the first inflow (10), and a second outflow (13) enriched in second fraction with respect to the second inflow (11). According to the invention, the elementary fractionation stage, which is non-static, is implemented in an elementary fractionation run, at which point at least one mass exchange buffer supply (15) is accumulated, and the elementary stage of fractionation is periodically initiated and repeated.

Patent CA-2292366-C (CA)
Inventor: TUKAMOTO KO
IPC: F04C18/02
Filed: 1999-12-13
Granted: 2002-10-01
Abstract: A scroll-type compressor includes a housing having a suction chamber with a suction port provided on a wall of the housing that opens into the suction chamber. The compressor also includes first and second scroll members at an angular and radial offset for forming fluid pockets, each scroll member having a spiral element. A groove is formed on an inner surface of the housing and an outer peripheral surface of one of the spiral elements. The groove extends in a circumferential direction of the housing at a position to include the suction port and forms an oil path for introducing oil into the interior of the housing when the compressor is assembled.      Because the oil path is formed regardless of the position of the scroll member, oil may be introduced into the interior of the housing through the suction port without generating an overflow of oil to the outside of the housing.

Inventor: NEIL IAIN A
IPC: G03B13/06
Filed: 2000-08-24
Granted: 2009-11-24
Abstract: An adjustable viewfinder optical system for a shoulder-supported movie or video camera having interchangeable objective lenses. The system includes first and second lens groups aligned on an optical axis for receiving and relaying an image received from the objective lens of the camera to the viewer's eye. The first lens group is in a forwardly extending portion of the viewfinder that is pivotally joined to a rearwardly extending portion of the viewfinder containing the second lens group. The forwardly extending portion has a telescoping portion for varying the eye position of the viewer relative to the camera in the fore-and aft direction. The light is collimated between the first and second lens groups at the telescoping portion, whereby the image viewed in the viewfinder remains in focus and the same magnification throughout the telescoping adjustment movement.

Title: Downhole apparatus
Inventor: ANDERSON CHARLES ABERNETHY
IPC: E21B7/24
Filed: 1998-04-22
Granted: 2006-09-19
Abstract: A downhole drilling assembly (10) comprises a body (11) for mounting on a drillstring, the body defining a fluid conduit. A drilling fluid driven motor (12) is mounted in the body (11) and is coupled to a flow restricting device (14) axially movably mounted to the body (11). The device is coupled to a drill bit (16). In use, the flow restricting device (14) is driven by the motor (12) to vary the flow of drilling fluid through the body and produce a varying fluid pressure force to induce axial movement of the device (14) relative to the body (11), and thus provide a percussive or hammer drilling effect. The flow restricting device (14) may be coupled to the drill bit (16) by a mandrel (46) splined or otherwise coupled to the body. Alternatively, the flow restricting device (68) may be coupled to the drill bit (72) by a rotatable shaft (70), such that the motor (64) may also rotate the drill bit (72).

Abstract: A lockable pill container is disclosed including a main body with a pluralit y of individual compartments for receiving pills. Each compartment has a lid member connected to the main body by a hinge permittin g it to be moved between open and closed positions. Each lid member has a downwardly projecting hook member that projects through an opening in the main body when the lid is closed. An elongated locking member is laterally inserted into the main body and transversely moveable relative to the hook members between first and second positions. In the first position, the elongated locking member engages the hook members of those lid members that are closed to lock them in the closed position. In the second position, the elongated locking member does not engage the hook members which may be opened and closed without the locking function. The elongated locking member is normally biased into the locking position by a transverse member that includes a downwardly projecting, externally accessible transver se member. The transverse member is formed from resilient material, which normally biases the elongated locking member to its first or locking position. The user may press the transverse member and thus move the elongated locking member against the bias to the second or nonlocking position. The elongated locking member may be selectively removed from the pill container to render the locking feature inoperative if the pill container is used in an environment where locking is not necessary.
