Patent CA-2249768-A1 (CA)
Inventor: WAIT MICHAEL R
IPC: B05D7/00
Filed: 1998-10-07
Abstract: A multiple layered waterproofing coating comprising a first, flexible layer having relatively high flexibility, adhesiveness and elongation properties, which is adapted to bridge cracks even in low temperatures, and a second, protective hard layer having high tensile strength and low adhesiveness properties. The layers are prepared from liquid formulations which are spray applied to the surface to be coated, primarily in below-grade foundations. The first, flexible layer is formed by spraying onto a surface a liquid formulation which provides a dried coating layer having high flexibility, adhesiveness and elongation properties. A second, protective layer is formed over the first, flexible layer by spraying over the first layer a liquid formulation which provides, when dried, a hard coating layer having high tensile strength and modulus, and low adhesiveness properties.

Abstract: The medicament comprises a carrier in the form of an active medicinal substance in a therapeutic dose onto which is transferred, using bioenergetic exchange, information from a potentiated medicament prepared according to homeopathic methods and having the same basic chemical formula or composition as the active medicinal substance. The proposed medicament preferably takes the form of a carrier containing the medicinal substance in a therapeutic dose to which is added (by embedding, dissolving or mixing) the potentiated medicament prepared according to homeopathic methods and having the same basic chemical formula (composition). The active medicinal substance and potentiated preparation can have identical or different medicinal forms. The invention is carried out by introducing the proposed medicament into the organism and by simultaneou action of the (separately prepared) medicinal preparation with the active medicinal substance in a therapeutic dose and the potentiated preparation of identical basic chemical formula (composition).

Title: Method and apparatus for preloading a skid plate for an early cutting concrete saw
Inventor: CHIUMINATTA ALAN R
IPC: B28D1/04
Filed: 1997-07-14
Abstract: A skid plate for a concrete saw has opposing ends connected by a truss, with mounting fixtures that connect opposing ends of a skid plate to the concrete saw. The mounting portions are connected to an apparatus that simulates the saw's mounting structure, and that simulates the load distribution the saw exerts on the skid plate in use.

Abstract: A four-piece table tennis table consisting of a first and second table top assembly. Each table top assembly including a first top section and a second opposing top section having a support assembly engageably disposed in relation thereto. In structural design, the support assembly has a first and second leg support pivotally mounted to the engagement surface of the table top assembly by means of one or more hinge members. In operation, the hinge members secure the first and second leg supports to the table top and further provide for the selective rotation of the first and second leg supports between an engagement position, disposed substantially perpendicular to the table top, and a retracted position, disposed contiguous the engagement surface of the table top. A first rigid leg and a second rigid leg, each having a general U-shaped configuration, positioned to selectively engage the opposing ends of the first and second pivotal leg supports, thereby providing a unitary support assembly for supporting the table top over a surface. The first and second rigid legs being selectively removable from engagement with the first and second pivoting leg supports and respectively disposed in relation to at least one retaining member secured to the engagement surface of the table top assembly. Correspondingly, the first and second pivotal leg supports may be selectively rotated into the retracted position for purposes of storage. Both table top assemblies of the present invention may then be stored in a side-by-side relationship, thus using a small amount of space for storage. Moreover, the present invention assists in the packaging of the component parts of the four-piece table tennis table for shipment in a relatively flat box having an outer dimensional periphery being only slightly larger than a single table top section of the four-piece table tennis table.

IPC: G01V1/104
Filed: 1999-04-23
Abstract: A system for creating seismic exploration shot-holes. A slender shaft is formed into the soil and the lower end of the shaft is underreamed to generate a cavity. An explosive material is positioned within the cavity and is detonated to generate seismic source energy. The slender shot-hole reduces the drilling material excavated and substantially reduces the seismic source energy dissipated upwardly through the shot-hole. The explosive filled cavity can be spherical, conical, hemispherical, or other shapes to maximize the transfer of seismic source energy from the explosive material to the subsurface geologic formations. The invention significantly expedites shot-hole drilling and provides an improved system for coupling the explosive material energy to the geologic formations.

Filed: 1999-06-03
Abstract: Longterm elevation of the intracellular Na /K+ ratio inhibits macromolecule synthesis and proliferation in the majority of cell types studied so far, including vascular smooth muscle cells (VSMC). We report here that inhibition of the Na+,K+ pump in VSMC by ouabain or 1 hr preincubation in K+-depleted medium attenuated apoptosis triggered by serum withdrawal, staurosporine or okadaic acid. In the absence of ouabain, both DNA degradation and caspase-3 activation in VSMC undergoing apoptosis were insensitive to modification of the extracellular Na+/K+ ratio as well as to hyperosmotic cell shrinkage. In contrast, protection of VSMC from apoptosis by ouabain was abolished under equimolar substitution of Na+o with K+o, showing that the antiapoptotic action of Na+,K+ pump inhibition was caused by inversion of the intracellular Na+/K+ ratio. Unlike VSMC, the same level of increment of the [Na+]i/[K+]i ratio caused by 2-hr preincubation of Jurkat cells with ouabain did not affect chromatin cleavage and caspase-3 activity triggered by treatment with Fas ligand, staurosporine or hyperosmotic shrinkage. Thus, our results show for the first time that similarly to cell proliferation, maintenance of a physiologically low intracellular Na+/K+ ratio is required for progression of VSMC apoptosis.

Title: Method and apparatus for providing background acoustic noise during a discontinued/reduced rate transmission mode of a voice transmission system
Inventor: KABAL PETER
IPC: G10L19/012
Filed: 1999-06-18
Abstract: In a voice communication system, a method and apparatus for generating natural-quality synthetic noise to replace background acoustic noise during speech gaps achieve a better representation of the excitation signal in a noise-synthesis model by classifying the type of acoustic environment noise into one or more of a plurality of predefined noise classes. The noise class information is used to synthesize background noise that sounds similar to the actual background noise during speech transmission. In some embodiments, the noise class information is derived by the transmitter and transmitted to the receiver which selects corresponding excitation vectors and filters them using a synthesis filter to construct the synthetic noise. In other embodiments, the receiver itself classifies the background noise present in hangover frames and uses the class information as before to generate the synthetic noise. The improvement in the quality of synthesized noise during speech gaps helps to preserve noise continuity between talk spurts and speech pauses, and enhances the perceived quality of a conversation.

Title: Time-versioned data storage mechanism
Inventor: GARDNER PAUL ANTON RICHARDSON
IPC: G06F17/30
Filed: 1999-07-26
Abstract: In a time-versioned storage mechanism, data is stored as a plurality of records, each including at least one attribute, a time span indicating the time span for which the attribute is valid, an insertion time indicating when the record was created, and a type field. The type field indicates whether the record is a concrete record, a delta record that possibly modifies the attribute value of a previous concrete or delta record, or an archive record replacing one or more records that have been archived. The data is accessed to find an attribute value from the point of view of a specified viewpoint time, by retrieving only records with insertion times not later than said viewpoint time, and constructing an attribute value from the retrieved records. The data is updated only by adding concrete records or delta records, without modifying attribute values in the concrete records or delta records.
