Title: Process for producing diisopropyl ether
Inventor: MARKER TERRY L
IPC: C07C43/04
Filed: 1995-03-20
Abstract: In process for the production of diisopropyl ether, a propylene-containing stream is contacted with isopropyl alcohol in a first stage in the presence of a catalyst under conditions to produce an effluent stream comprising diisopropyl ether. At least a portion of this effluent stream is recycled to a second stage where the diisopropyl ether is reacted with water to produce isopropyl alcohol. The isopropyl alcohol is then recycled to the first stage. The benefit of producing isopropyl alcohol by the hydration of diisopropyl ether is that it is an easier reaction than, for example, the hydration of propylene. As a result, the process of the present invention can operate under less severe conditions, i.e., less cost.

Title: Tunable add/drop optical filtering method and apparatus
Inventor: GLANCE BERNARD
IPC: H04J14/00
Filed: 1995-07-17
Abstract: The present invention includes a tunable add/drop filter that utilizes the unique operational characteristics of a wavelength grating router.  The filter comprises a 1 x N switch, a wavelength grating router (WGR) having a plurality of inputs and outputs, and a multiplexer.  The WGR demultiplexes an incoming wavelength division multiplexed (WDM) signal, providing the frequency components of the WDM signal at different outputs.  The WGR outputs include a set of retain outputs that are coupled directly to the multiplexer and a drop output that is connected to a drop line.  The particular WDM signal frequency component that is provided to the drop output depends directly on the WGR input at which the WDM signal is received.  The 1 x N switch controllably provides the WDM signal to the proper WGR input so that a select frequency is provided at the drop output, which in turn drops the select frequency from the WDM signal.  The undropped signals, as well as any added signals are multiplexed into a new WDM signal by the multiplexer.

Title: Adjustable Injection Molding Apparatus for Creating of Products Within a Mold from Fluid Plastic Material
Inventor: DONNELL EMERSON BRADFORD JR
IPC: B29C45/23
Filed: 1996-03-21
Abstract: An improved design for an injection molding apparatus for creating of products from fluid plastic material wherein a hydraulic flow divider can be used for simultaneously actuating of multiple hydraulic injectors which need not be linearly positioned.  This molding apparatus is usable with a hydraulic flow divider since a unique configuration of a fixed frame with a cage mounted movably therein and a hydraulic cylinder assembly mounted movably within the cage allows the injection molding apparatus to use the same amount of hydraulic fluid during each and every stroke regardless of the length of the stroke of the rod relative to the nozzle.  This unique capability is achievable by allowing the hydraulic cylinder assembly in its entirety to move within a predefined cage configuration even after the entire stroke is completed in order to allow the cylinder to accept the amount of powering hydraulic fluid associated with a single complete stroke.  Further included in this design is a unique position indicating device located externally on the apparatus to indicate the relative positioning internally between the nozzle rod and the nozzle rod tip opening and to indicate the positioning of adjustment thereof.

Title: Three-dimensional processing system
Inventor: KAWAMOTO MEITETSU
IPC: G05B19/42
Filed: 1996-04-01
Abstract: A three-dimensional  processing device  can measure three-dimensionally  the  contour  of  a  person's  face including hair by laser beams without the necessity of the person to be measured to move or to fit into a specific line for measuring.   In order to move a person to the required position,  a positioning device,  for example a backboard,  is fixed adjacent to this required position. Positioning is performed by leaning against the backboard or by providing a concave part on the backboard and fitting one's shoulder into the concave part.  A laser scanner is installed on a scanner stand so that it is possible to move it forward, backward, up, down,  left and right.   It is possible to distinguish the backboard from hair, from which laser beams are not reflected by making the backboard black or almost black. It is then possible to measure a shape of a person  by  reflection  of  the  laser  beams  off  the backboard.

Title: Drug delivery ptca catheter and method
Inventor: GOODIN RICHARD L
IPC: A61F2/958
Filed: 1994-10-14
Abstract: An intravascular material delivery dilation catheter ( 10) having a pair of longitudinally spaced inflatable balloons (20, 22) with a drug delivery region (26) defined therebetween. The catheter is ideally suited for use after a PTCA procedure, wherein the proximate balloon (20) seals the blood vessel while the distal balloon (22) is uniquely contoured when inflated to define fluid communication paths (60) therepast and proximate a blood vessel (54) to be treated. The distal balloon (22), when inflated, has four lobes but could also be textured. Each lobe is separated from the next by a groove, which groove in combination with the blood vessel inner wall forms a fluid communication path therebetween. Upon inflation of both balloons (20, 22) in a blood vessel (54), a medicament such as heparin can be injected, via the drug delivery region (26) between the inflated balloons (20, 22), wherein the medicament flows past the distal balloon (22) at a selected rate. Accordingly, a medicament can be injected directly to a treatment site rather than injected as a bolus dose, thus, a smaller dosage may be employed to minimize side effects. Alternatively, perfusion can be accomplished by only partially inflating the proximate balloon (20) to constrict flow therepast, or eliminating the proximate balloon (20) entirely, where the drug delivery region is disposed upstream of the contoured distal balloon (22).

Abstract: In a speech decoder which experiences frame erasure, the pitch delay associated with the first of consecutive erased frames is incremented. The incremented value is used as the pitch delay for the second of consecutive erased frames. Pitch delay associated with the first of consecutive erased frames may correspond to the last correctly received pitch delay information from a speech encoder (associated with a non-erased frame), or it may itself be the result of an increment added to a still previous value of pitch delay (associated with a still previous erased frame).
Patent CA-2177436-A1 (CA)
Inventor: MAKAL JOHN MITCHELL
IPC: H01R13/53
Filed: 1996-05-27
Abstract: Apparatus and methods for reducing the risk of flashover during loadbreak operations of insulated separable connectors. In one aspect, the flashover distance for an electrical connector assembly is increased by supplementing exposed conductive portions of the male connector with insulated portions such that energized points on the energized connector are placed a greater distance away from the nearest ground plane on the complimentary connector. The additional insulation compensates for reductions in dielectric strength of the air occurring during separation of the male connector from the female connector. Also, the semi-conductive ground shield of the bushing is supplemented by an insulating sleeve. The insulative sleeve effectively removes a common ground plane to which an arc might tend during a flashover. In another aspect, a substantial airtight seal is prevented between elastomeric seals of the female connector and the probe of the male connector. The connection being thus vented, the available volume of air surrounding the energized components of the connector assembly is increased. In described embodiments, the probe portion of the elbow is configured to prevent substantial sealing between the connector components. An annular reduced diameter recess is located between the probe's metal rod and its arc follower and is elongated to prevent substantially airtight sealing between the elbow and bushing during the initial stages of the loadbreak operation itself. In alternative embodiments, the probe may be hollow and vented or include a groove disposed along its length.
