Title: Method of repairing buried sewage pipes
Inventor: MUELLER HANS
IPC: F16L55/18
Filed: 1992-07-28
Abstract: METHOD OF REPAIRING BURIED SEWAGE PIPES              ABSTRACT OF THE DISCLOSURE   .       A damaged (e.g., cracked) portion of a buried sewage pipe is repaired by permeating one or more layers of fibrous material with a hardenable plastic compound (such as epoxy resin), convoluting the thus obtained mat around a radially expandible length of hose, introducing the hose into a selected defective portion of the pipe, expanding the hose and the convoluted mat so that the mat engages the internal surface of the pipe, deflating the hose, and with-drawing the hose from the pipe, preferably after the plastic compound has set.  A film of polyethylene is inserted between the external surface of the hose and the internal surface of the convoluted mat to enhance friction and to thus compel the hose to turn in the course of the expanding step.  Expansion of the hose results in expulsion of some plastic compound beyond the peripheral surface of the convoluted mat; such compound bonds the expanded convoluted mat to the pipe and at least partially fills the crack to cracks in the adjacent portion of the pipe.  Some plastic compound is also expelled at the axial ends of the convoluted mat to form a smooth transition between the internal surface of the pipe and the internal surface of the expanded convoluted mat.

Title: Solid state ion sensor with polyurethane membrane
Inventor: BROWN RICHARD B
IPC: G01N27/414
Filed: 1991-05-02
Abstract: A polyurethane matrix is employed to form a substance-sensitive membrane which is particularly suited for installation on a solid state sensor. The ionophore may be a potassium ionophore, an ammonium ionophore, or any other ionophore may be coupled to the molecule of interest through a bioactive agent, such as an enzyme, an immuno-chemical, bacteria, antibody, virus, or antigen. The resulting substance-sensitive membrane has electrochemical properties which compare favorably to those of conventional PVC membranes, and exhibit significantly greater adhesion to glasses and semiconductor substrate materials. The improved adhesion will prolong the life of the sensors and prevent the formation of electrolyte shunts which have been known to render solid state sensors inoperative.

Patent CA-2086472-A1 (CA)
Inventor: KAJITA KOJI
IPC: H04N1/32
Filed: 1992-12-30
Abstract: An image processing apparatus for preventing counterfeiting by adding information to read image signals and arranging a mark indicative of a position where the information is added so that the additional information can be easily extracted.  An image processor processes full-colour image signals from a line sensor and a binarization circuit binarizes the signals using a pseudo half-tone processing.  A density judgment circuit judges the density of the image signals and controls a modulator which adds additional information.  The modulator refers to the contents of a ROM and changes dot positions in the binarized image signals based on the referred information and adds the additional information to the image signals.  A FIFO compensates image signals delayed by the density judgment circuit.

Title: Analogs of botanic seed
Inventor: CARLSON WILLIAM C
IPC: A01C1/06
Filed: 1991-10-24
Abstract: Analogs of botanic seed are disclosed.  According to one embodiment, a seed analog comprises a unit of totipotent plant tissue disposed relative to a unit of non-phytotoxic hydrated gel that is "oxygenated,"  i.e., has a concentration of molecular oxygen that is higher than a concentration of molecular oxygen that would otherwise be absorbed from the atmosphere by the hydrated gel at standard temperature and pressure. Gel oxygenation can be by exposure to a gas having an enriched concentration of molecular oxygen relative to the earth's atmosphere or by including in the hydrated gel an oxygen-carrying or oxygen-absorbing compound such as a perfluorocarbon and/or silicone oil. An outer shell can be included that, with the hydrated gel, forms a capsule enclosing the unit of totipotent plant tissue. According to another embodiment, the seed analog includes a shoot restraint that is resistant to penetration by a growing shoot and/or cotyledons. In such seed analogs, the unit of totipotent plant tissue has a shoot end, and the restraint is disposed relative to the shoot so as to prevent, during germination of the totipotent plant tissue, entrapment of the shoot end in the seed analog.  Also disclosed are corresponding methods for germinating totipotent plant tissue and for manufacturing seed analogs, all of which especially are useful for producing large numbers of genetically identical plants.

The spark gap device thus installed is especially suitable for use in miniature filter connectors of the type in which the filters are capacitor chips positioned in recesses of the connector housing between an electrical contact and a ground clip, the spark gap device replacing a capacitor chip in one of the recesses.
Patent CA-2096228-A1 (CA)
Inventor: OXMAN JOEL D
IPC: A61K6/90
Filed: 1991-11-12
Abstract: Numerous patents teach the use of various complexes of cobalt, rhodium, nickel, palladium, or platinum as catalysts for accelerating the thermally-activated addition reaction (hydrosilation) between a compound containing silicon-bonded hydrogen and a compound containing aliphatic unsaturation. Although platinum complexes and many others are useful as catalysts in processes for accelerating the thermally-activated addition reaction between the compounds containing silicon-bonded hydrogen and compounds containing aliphatic unsaturation, processes for promoting the ultraviolet or visible radiation-activated addition reaction between these compounds are much less common. This invention provides a process for the addition reaction of compounds containing silicon-bonded hydrogen to compounds containing aliphatic unsaturation and compositions suitable for said process. The process is activated by actinic radiation and is conducted in the presence of a platinum complex having one cyclopentadienyl group that is eta-bonded to the platinum atom and three aliphatic groups that are sigma-bonded to the platinum atom and a free-radical photoinitiator that is capable of absorbing actinic radiation such that the hydrosilation reaction is initiated upon exposure to actinic radiation. The invention also provides compositions for use in the aforementioned process.

Title: Load sensing hydraulic control system
Inventor: BIANCHETTA DONALD L
IPC: F15B11/00
Filed: 1991-04-22
Abstract: The use of a pair of small variable displacement hydraulic pumps in a hydraulic system offers some advantages. The output of the two pumps of the known systems is normally not combined, but is selectively combined under a majority of the operating conditions.  The subject load sensing hydraulic control system (10) has first and second hydraulic circuits (13, 14) with each circuit having a plurality of pilot operated control valves (21, 22/49, 50, 51) operatively connected to a variable displacement pump (16, 46).  The output flow of both pumps (16, 46) is normally made available to both hydraulic circuits through a combiner valve (106) so that the output capability of both pumps can be used to satisfy the demand for fluid by a single control valve or by one or more of the control valves from each circuit. A valve arrangement (111) connects the highest load pressure of the control system to both pumps when the output flow thereof is being combined. Under certain operating conditions of some of the control valves, the combiner valve (106) and the valve arrangement (11) are selectively moved to a position to isolate the first and second hydraulic circuits from each other and to direct the highest load pressure of each circuit only to the displacement controller (27, 57) of the pump (16, 46) connected to that circuit.
