Title: Optical frequency translator
Inventor: KAMINOW IVAN P
IPC: H04B10/2581
Filed: 1995-02-28
Granted: 2000-04-25
Abstract: An optical frequency translator includes a frequency routing device formed on a semiconductive wafer between two reflective facets forming a laser cavity. Waveguides associated with the device each contain an integrated optical amplifier selectively acting as a gate preventing the flow of optical energy through a respective waveguide or as a gain-providing element which amplifies optical energy flowing through a respective waveguide. When a selective one of the optical amplifiers is activated with bias current the optical energy produced by this current operates in conjunction with the optical energy of the input signal so that lasing action occurs between the reflective facets. The lasing action occurs along a predetermined path determined by the optical amplifier or amplifiers that are activated. The lasing action in this particular path is supported at a particular selected frequency. This particularfrequency is the frequency to which the input signal is to be translated. An input waveguide is provided for injecting the input signal into the laser cavity. A separate output waveguide may be provided. Alternatively, the input and output signals may be transmitted on the same waveguide. A gain member such as a saturable absorber, for example, may be disposed in the laser cavity which optically couples the input waveguide to the frequency routing device.

Title: In-line application of solid lubricant to steel strip
Inventor: SPEARIN ELLIOTT Y
IPC: C10M101/02
Filed: 1995-04-26
Granted: 1999-07-06
Abstract: A solid lubricant application procedure is combined in-line with a steel strip processing method which comprises processing steps upstream and downstream of the lubricant application procedure.          The latter comprises applying the lubricant material in molten form or as a solution and may include temperature adjusting steps both upstream and downstream of the lubricant material-applying step.          The space for incorporating the lubricant application procedure into the steel strip processing line is limited.  The strip speed in the lubricant application procedure is synchronized with the strip speed normally attained in the steel strip processing method in the absence of an in-line lubricant application procedure.  The steps of the lubricant application procedure are constrained to accommodate the space limits and strip speed synchronization requirement imposed on the lubricant application procedure when it is combined in-line with the steel strip processing method.

Title: Use of liposome encapsulated ciprofloxacin as an immunotherapeutic drug
Inventor: WONG JONATHAN P
IPC: A61K31/495
Filed: 1996-04-23
Granted: 2000-07-11
Abstract: Liposome-encapsulated quinolones and specifically liposome-encapsulated ciprofloxacin dramatically enhances macrophage functions, induces NO production and augments the production of cytokines, rendering the composition an immunoprophylactic and immunotherapeutic agent with unique clinical potential.  Liposome-encapsulated ciprofloxacin and other quinolones could be extremely useful in antimicrobial, anticancer and AIDS therapies.  In such cases, the immunological status of the patient is often compromised or suppressed, making them susceptible to microbial infections and to the development of tumor growth.  Selective augmentation of cellular immunity by activation of the microbicidal and tumoricidal activities of macrophages, induction of NO and cytokine production could be of primary importance to such patients in terms of protecting them against microbial infections and inducing their cellular host defence to tumor cells.

Title: Method of printing a multiple color image using heat sensitive inks and applying a polymer surface preparation material to a substrate
Inventor: HALE NATHAN S
IPC: B41M3/00
Filed: 1995-01-26
Granted: 2009-04-07
Abstract: An image is permanently transferred to a substrate having a cotton component, or an absorbent component, from a medium printed with the image. When using a thermal printer and heat activated ink, a polymer surface preparation material and the ink are transferred by the thermal printer to the medium fr om a ribbon, without activating the ink or the surface preparation material durin g this first transfer. When using a computer driven printer, a polymer surface preparatio n material is printed by the computer onto the medium and over the image witho ut printing the material beyond the margins of the image. When using color thermal ink jet printers, heat sensitive inks containing a polymeric surface preparation may be used as an ink formulation. The image is then transferred from the medium to the substrate by applying sufficient heat and pressure to the medium to activate and transfer the ink and the surface preparation material, with the surface preparation material bonding the ink to the substrate.

Abstract: A vacuum cleaner head, for attachment directly to a vacuum cleaner body having a central longitudinal axis, has exposed bristles with remote ends on a plane off-set by about 70° to the central axis. The bristles 14 and 15 extend along opposing sides of a lower surface of the head in strips at either side of a channel 18 through which dust and debris gathered up by the bristles passes into the vacuum body. The off-set plane means that when the body is held directly or by a handle, a natural comfortable sweeping action, with the handle axis at about 20° to the vertical, keeps both strips of bristle in contact with the swept surface.

Abstract: The present invention relates to a manure distributor for substantially equally distributing the manure pumped from a holding tank into a number of hoses that spread the manure over farm fields. The manure distributor comprises a cylindrical casing defining an inner chamber divided into a lower and an upper portion by an annular transverse partition wall fixedly attached to the casing. A cylindrical baffle downwardly extends from the inner edge of the annular partition wall into the lower chamber portion, in which the manure is fed. The upper end of the distributor is equipped with a rotor having several arcuate blades radially extending therefrom. In use, the manure fills the inner chamber until it overflows into its upper end, where the rotating rotor blades outwardly propel the manure through outlet openings made in the peripheral wall of the distributor casing, at its upper end. The manure is then directed into rigid distribution pipes to which are connected the flexible spreading hoses. Knives are provided on the outlet openings to help prevent clogging of same by shearing action against incoming manure. Air valves are provided on the distribution pipes to prevent the pressure from dropping therein.

Filed: 1995-12-06
Granted: 2008-01-22
Abstract: The present invention utilizes the smooth con-tinuous motion of a masking belt to concentrate air--entrained absorbent materials on the surface of a moving fibrous substrate. Air flowing through the open areas of the masking belt carries the entrained material into the fibrous web. The fibrous web acts as a filter to separate the entrained material from the air stream. Substantially all dispensed material is captured by the fibrous web, and expensive and complex absorbent material recycle systems can be eliminated.

Abstract: A tool for controlling azimuth and/or inclination in a wellbore and methods for utilizing the same is disclosed.      The tool generally comprises a freely rotating mandrel, for transmitting drilling forces, contained within two eccentric sleeves. The outer sleeve has an eccentric longitudinal bore that forms a pregnant or weighted side that seeks the lowside of the wellbore.

The inner sleeve has a further eccentric longitudinal bore that contains the freely rotating mandrel. The mandrel is attached to the drill string at one end and to the drilling bit at the other. The position of the inner sleeve may be controlled, at will from the surface, so that the eccentric is kept to one side of the outer housing, thus transmitting a fulcrum force to the bit and controlling the azimuth and/or inclination of the wellbore.      The pregnant housing contains drive means and assorted logic for controlling the position with respect to the pregnant housing of the eccentric bore of the inner sleeve.
