Title: Pharmaceutical compositions and their use for treating zinc deficient disorders
Inventor: PICKERING ROBERT J
IPC: A61K31/30
Filed: 1993-02-17
Abstract: A zinc depot for animals may be established through the introduction of a zinc substance exhibiting slow-release characteristics for the physiology of the animal, preferably via a non-digestive route. A fluid or paste-like composition, or a bolus, may be introduced through preferred routes such as into the bloodstream, intramuscularly, or subcutaneously. Preferred zinc substances include zinc organic salts and a specified range of preferred zinc inorganic compounds. Most exhibit a low aqueous solubility, less than or equal to 0.01 g/ml of H2O at 35 ·C. Other agents may enhance the effectiveness of the zinc substance, preferred agents including calcium, magnesium or selenium containing compounds or minerals, fatty acids, vegetable oils, and/or sulphur or sulphide compounds. The provision of a lasting zinc depot in an animal is useful for addressing zinc responsive disorders, both in a preventative and remedial sense. Examples of zinc-responsive disorders include facial eczema, fading elk's disease, mycotoxin poisoning, poisoning from alkaloid substances, disorders relating to phyto-oestrogen levels, and zinc deficiencies.

Patent CA-2134494-A1 (CA)
Inventor: HECHT DAVID L
IPC: G06K1/12
Filed: 1994-10-27
Abstract: A self-clocking glyph code is composed of data glyphs which encode logically ordered data values, together with one or more multi-glyph synchronization code patterns. Each of the synchronization code patterns is distinguishable from the data glyphs, but the synchronization code pattern or patterns provide an explicit spatial reference for the data glyphs. To this end, the glyphs of the synchronization code pattern or patterns are written on the recording medium in accordance with the same spatial formatting rule as the data glyphs, plus at least one additional formatting rule that establishes a predetermined geometric relationship between the glyphs of the synchronization code pattern or patterns and corresponding ones of the spatially formatted data glyphs, such that the logical order of at least a significant number ( ~ 1) of the data glyphs is inferable from the synchronization code pattern or patterns. Preferably, each of the synchronization code patterns is composed of glyphs that are selected from the same finite symbol set as the data glyphs, so the synchronization code pattern or patterns typically are defined by glyph patterns that have a suitablyhigh statistical probability of being unique with respect to any pattern of dataglyphs.

Title: Fiberoptic illuminator for infant care
Inventor: NICHOLAS HOWARD B
IPC: G02B6/00
Filed: 1995-01-09
Abstract: An illuminator for use with a variety of end use light emitting devices for administering light for therapy and/or observation of an infant. One of the end use emitting devices is a device to provide phototherapy to the infant and is prevented by the illuminator from emitting light that has not been filtered to select the desire spectrum of wavelengths for phototherapy. The illuminator prevents the introduction of a connector to the phototherapy device from being inserted to an operative, secured position unless the proper filter is in position to filter out all of the undesired wavelengths before the light radiation can reach the phototherapy end use emitting device. Other end use light emitting devices may, however, be used with the same illuminator and their connectors are readily inserted into the illuminator to receive light radiating from the illuminator to the end use light emitting device.

Patent CA-2146272-A1 (CA)
Title: Multiple-completion packer and locking element therefor
Inventor: ARIZMENDI NAPOLEON
IPC: E21B33/1295
Filed: 1995-04-04
Abstract: The invention relates to a multi-bore packer that has an annularly shaped sealing element. The assembly has a series of strings that run continuously so that they can be supported from the surface. At least one hub segment straddles the strings and is sealed in between. The entire assembly features one of the hubs with a sealing element. The outer sealing element, when compressed, seals against a casing or wellbore as well as against one of the hubs through which the strings extend. A greater effective piston area allows setting with surface pressures below 2500 psig. A provision is made in the assembly of hubs to provide for an operating mechanism to compress the outer seal between the casing and the hub, by increasing the applied sealing forces on the outer seal, should well conditions apply greater differential pressures, in either direction, to the outer seal than the original setting pressure used. A longitudinal lock is provided between a movable piston segment and one of the hubs to avoid actuation of the outer seal against the casing until a predetermined force is applied. During make-up, a secondary lock can be applied to the locking mechanism for pressure-testing purposes of the strings which run through the hubs. Finally, the lock mechanism features a design which retains a movable piston stationary after its actuation for release of thelock. Back-and-forth movement is prevented which may have a detrimental effect on the seals surrounding the movable piston in the lock assembly. Therefore, after the tool is set when the lock is unlocked, the piston componentof the lock remains in a substantially fixed position, despite pressure fluctua-tions in the wellbore which would have otherwise urged the piston to move in opposed directions.
