Title: Member with holes and process of making same
Inventor: GRENDAHL DENNIS T
IPC: B29C65/00
Filed: 1993-05-25
Abstract: Member (118) of polymethylmethacrylate, polysulfone or a like material with a plurality of holes (120) arranged in a predetermined, geometrical configuration. The holes are derived through a procedure of repetitive drawing. Prior to the first drawing operation, a workpiece of base material is provided which has a plurality of holes therein. Each of the holes is filled with a material which is soluble in certain particular solvents, yet drawable along with the base material. The workpiece can be drawn to a reduced cross-sectional area such as a square, the reduced cross-sectional workpiece positioned with respect to each other and drawn again in further operations to a completed, fenestrated member. The member can be utilized as either a contact lens, an intracorneal inlay, an intraocular lens, a medical filter, or other applications requiring fenestrated structures.

Patent CA-2165485-A1 (CA)
Inventor: SAYAG MICHEL
IPC: H04N5/32
Filed: 1995-12-18
Abstract: A solid state image sensor CCD array (10a) has a two block, full-frame, parallel-register structure. The two blocks of the array, each comprised of photosensitive radiation sensors or pixels (20), feed into a single centrally disposed serial read-out register (10b) so as to form one unified photosensitive domain. The read-out register is photosensitive except for two associated narrow clock buses (H1, H2) that are spaced apart so as to only block a minimum of input radiation in any one pixel (22) of the read-out register. Each stage of the read-out register can act as a pixel that is approximately square and that is approximately the same size as the pixels of the two full- frame blocks. In operation, the centrally disposed read-out register can be stationary for a significant first portion of a total frame time (integration period), and then in a latter part of the frame time it can be read out one or more times to provide exposure update information for all of the pixels of the array. Typical examples of applications include advanced histogram-based, or other types of, X-ray exposure optimization. The array avoids the use of an "amplifier corner" that is characteristic of most if not all area image sensors. As such, all four corners of the array can be shaped to suit a particular application. One application of particular interest is for intra-oral dental X-ray imager and system.

Title: Method and apparatus for providing a stream of inert gases in underbalanced drilling of a well bore
Inventor: MOODY EUGENE I
IPC: E21B10/18
Filed: 1995-12-21
Abstract: A method and apparatus is provided for use in underbalanced drilling of a well bore.  A stream of substantially inert gases is provided by cooling, treating and compressing a stream of exhaust gases.  The exhaust gases are cooled to a temperature less than 100°F in a quench tower and a heat exchanger.  The cooled gases are treated to reduce their acid content and then compressed to a pressure suitable for underbalanced drilling.  The compressed exhaust gases can then be used as the drilling fluids.  They may or may not be mixed with atmospheric air or drilling mud.

Title: Analytical method for evaluating flavor stability of fermented alcoholic beverages using electron spin resonance
Inventor: ONO MIYOKO
IPC: C12C7/28
Filed: 1995-12-27
Abstract: Quantitative determination and evaluation of the flavor stability of fermented alcoholic beverages are performed by measuring the changes of the amounts of spin adduct from the formation behavior of active oxygen with passage of time using an ESR apparatus and either determining the value on the time axis of the inflection point of changes of the amounts of spin adduct (defined as the active oxygen formation lag time) or determining the amount of spin adduct after a predetermined time has elapsed after the start of measurement (defined as the active oxygen formation activity). The longer the active oxygen formation lag time or the lower the active oxygen formation activity, the greater the oxygen resistance of the fermented alcoholic beverage, thus making it possible to evaluate that fermented alcoholic beverage as having good flavor stability. In addition, if the formation behavior of active oxygen of semi-finished products in the production process is measured in the same manner, the quality of flavor stability when that semi-finished product has become a finished product can be predicted and evaluated.

Title: Overhead pusher lug assembly for packaging machines
Inventor: DISRUD JEFF A
IPC: B65G19/26

Title: Basket-style carrier with non-collapsing end panels
Inventor: HARRELSON GLEN RAY
IPC: B65D71/28
Filed: 1995-09-12
Abstract: A basket-style carrier (10) constructed so as to maintain the carrier open during loading. End panels (16, 16) of the carrier are formed from overlapping end panel flaps (26, 28). Each end panel flap is connected to an individual handle panel support (34) by a fold line. Each overlapping end panel flap includes a wide portion that extends transversely beyond a fold line connecting it to the handle panel support. This causes the two sections to function as a unit, preventing the end panels from collapsing about their fold lines during loading. In addition, a bottom panel forming flap (67, 67) is individually connected to each end panel flap at each end of the carrier. Each bottom panel forming flap is adhered to a bottom panel flap (64).

Patent CA-2184035-A1 (CA)
Inventor: MATTEAU ROBERT
IPC: A24D1/00
Filed: 1996-08-23
Abstract: A non-smokable tobacco product comprises a rod or stick-shaped element of cigarette tobacco with a filter element at one end and both enclosed by a tubular wrapper.          The product is rendered unsmokable by a series of apertures extending through the wrapper adjacent the filter so that when air is drawn through the filter substantially all of the air enters through those apertures, there being insufficient air flow through the tip end to propagate normal cigarette combustion of the tobacco at that location and to permit any appreciable amount of smoke from reaching the smoker's mouth.          The product is rendered smokable by covering the apertured region of the wrapper by means of a strip a sliding band or ring which blocks air flow through the apertures and thus converts the product into a self-made cigarette that can be smoked in the manner of a regular cigarette.

Abstract: A device (10) and method for monitoring particulate (22) flowing through a conduit (20) has a transmitter (16) and a receiver (18) positioned in optical alignment on opposite sides of the conduit (20). A light beam (50) is transmitted across conduit (20) from the transmitter (16) to the receiver (18). Particulate (22) flowing through conduit (20) interrupts light beam (50) causing a signal to be generated from which particulate concentration is determined. A calibrator assembly (40) has a motor (64) adapted to move a filter (100) having a selected percentage opacity within the path of light beam (50). Movement of the filter (100) modulates light beam (50) and a signal corresponding to the concentration associated with the percentage opacity is generated.
