Patent CA-2119048-A1 (CA)
Inventor: RESLOW LEIF F
IPC: B41F31/08
Filed: 1994-03-15
Abstract: To maintain required or desired ink transfer capability of an anilox roller (6) after wear and tear caused, for example, upon engagement of the surface of the roller against a doctor blade (7a, 7b) of a chambered inking unit (7), the ink receptor depressions or cells (14,514) in the surface of the roller are formed with a depth which is substantially greater than that necessary for the volumetric dimension for required or desired retention of ink suitable for transfer upon printing with a predetermined print density. Before application of printing ink thereto, the cells are filled with a removable filler material (20), for example copper, plastics such as polyethylene, epoxy, wax or the like. After the surface of the strips or ridges or cell walls becomes worn, a portion of the filler material is removed, for example by vaporization, by a laser, etching or the like, to reconstitute the original volume for ink retention. The change in print density upon printing, as the surface wears, is abrupt (Fig. 4: tB) and, when that change is determined, the volume-reconstituting step is carried out. If the surface of the roller itself is a layer which is readily machinable, for example made of copper, the initial depth of the cells (14,514) may be for the initial requirement of ink retention. The layer thickness is then originally made thick enough so that, upon sensing of the abrupt change in print density, for example based on time or on printing results, the depth of the cells still present in the roller can be increased, e.g. by a laser, to obtain and reconstitute the volumetric dimension for desired ink retention.

Title: Ophthalmic pachymeter and method of making ophthalmic determinations
Inventor: SNOOK RICHARD K
IPC: A61B3/107
Filed: 1994-07-05
Abstract: An ophthalmic pachymeter which is highly effective in aiding in the determination of thickness and the optical density of the cornea of an eye an a real-time basis. The pachymeter therefore lends itself to effective employment in aiding in radial keratotomy and other surgical procedures With respect to the eye. The ophthalmic pachymeter of the invention has three major subsystems which include a television camera, a multiple slit projector and an associated processing and display system. In a broad form, the invention comprises illuminating a selected portion of the cornea, moving a slit across the cornea and generating Tyndall image ray paths for enabling, analysis of the optical density of the cornea and the thickness of the cornea. This is accomplished through a series of digitally-encoded television images of the optical section of the cornea produced by a multiple slit projector and which images are then subjected to digital analysis. A locus of each of the significant elements of the reflected image of the anterior portion of the eye is defined. In this way, the optical character of the cornea/air interface is compared with the corrected reflectance of the stroma and the endothelium, in order to determine relative transparency. A density map may be constructed in parallel slices far display as a three-dimensional plot of the frontal surface shape of the cornea and for defining and displaying the local thickness, the posterior surface contour, and the optical density of the cornea.

Title: Permanent Wave Composition and Method
Inventor: NEILL PAUL
IPC: A61K8/40
Filed: 1995-02-08
Abstract: A mild permanent wave reducing agent-containing composition and method of permanently waving or straightening human hair that provides a strong, long lasting curl, or long lasting straight hair formation, while minimizing hair damage. The composition includes two ionic compounds, one cationic and the other anionic, that complex in solution over a molar ratio of cationic compound to anionic compound in the range of about 1:1.2 to about 1.2:1, preferably in the range of about 1:1.1 to about 1.1:1, to provide synergy in waving efficiency, thereby providing a strongly reconfigured hair configuration (curled or straightened). At least one of the ionic compounds functions as a reducing agent for hair, capable of breaking the disulfide bonds in the hair so that the bonds later can be reformed via oxidation, when the hair is in the desired configuration. Examples of cationic compounds include thiocholine, choline, cysteineamide, cysteamine, and combinations thereof.      Examples of anionic compounds include cysteine, N-acetylcysteine, thioglycolic acid or its salts, and combinations thereof. The preferred ionic compounds are thiocholine and N-acetylcysteine. The composition is effective over a wide pH range of about 4 to about 12, especially about 5.0 to about 9.4, preferably in the range of about 5.5 to about 8.5, and more preferably at a neutral pH of about 7.0 ~ 1Ø
Patent CA-2142384-A1 (CA)
Inventor: SIMONAR DAVID M
IPC: E04F19/04
Filed: 1995-02-13
Abstract: A fastener comprised of six main components: 1) molding; 2) a molding clip; 3) a ring receptacle; 4) a retainer ring; 5) a circular shaped male snap; 6) a nail or screw to attach the male snap component to a flat mounting surface. The combination of which securely fastens molding to flat surfaces. The molding, which has a flat bottomed dovetail groove that runs the entire length on the back face of the molding, accepts the molding clip, ring receptacle and retainer ring. The molding clip assembly is held firmly in the molding groove by inserting the ring receptacle into the molding clip and thereby forcing the outward facing arms at the bottom of the clip into the inside walls of the molding groove. The molding clip, ring receptacle and retainer ring when used in combination with the molding groove, can then be forced over the male snap which in turn is fastened securely to a flat mounting surface. The resultant is molding being fastened securely to a flat mounting surface and which makes the molding completely removable and replaceable.

Inventor: GEE THOMAS A
IPC: F16H57/04
Filed: 1995-02-14
Abstract: A gear device is disclosed, such as a change gear transmission of the countershaft (21) type in which, mounted for rotation about the countershaft is a larger gear (17) and a smaller gear (29). The transmission housing (11) defines a first lubricant reservoir (R1), having a nominal fill level (L1), which is able to lubricate the smaller gear as it rotates. A partition member (51) is disposed around the larger gear and defines a second lubricant reservoir (R2) through which the larger gear passes as it rotates. The partition member defines fluid passages (71,73) providing restricted communication from the first reservoir to the second reservoir. The fluid passages (71,73) are sized such that as the larger gear rotates, carrying lubricant out of the second reservoir (R2), there is maintained in the second reservoir a second fill level (L2), below the first fill level (L1) such that at least a portion of the teeth of the larger gear (17) pass just below the second fill level as the larger gear rotates. The result is substantially reduced churning losses, without decreasing the ability to lubricate the smaller gears.
