Patent CA-2117956-A1 (CA)
Inventor: SEIGNEUR ROBERT LOUIS
IPC: B65G69/28
Filed: 1994-10-12
Abstract: A portable ramp for providing a bridge between a ground level surface and a raised surface. The ramp includes a support plate having a substantially horizontal first portion adapted to rest along an edge of the raised surface. A second portion of the plate extends vertically downward from the first portion and a third portion extends generally outwardly from the second portion in a direction generally toward the ground level surface. The third portion of the plate member supports one end of an angled beam which extends at a generally predetermined angle from the plate to the ground level surface. The opposite end of the beam is supported with respect to the ground level surface by a resilient foot member which provides stability. A traction plate having upwardly projecting portions is attached to a top surface of the beam intermediate the support plate and foot member in order to increase friction and provide traction along the inclined beam.

Patent CA-2121383-A1 (CA)
Inventor: GEUS HANS G
IPC: D01D5/098
Filed: 1994-04-15
Abstract: ABSTRACT OF THE DISCLOSURE         A spun-filament nonwoven web is deposited on a sieve belt from a spinning head producing a curtain of thermoplastic filaments which traverse a cooling chamber by drawing the filaments in a drawing nozzle separate from the cooling chamber and passing the filaments through a delivery unit and the form of a jet pump, air flow through which is controlled at least in part by a suction blower below that sieve belt. Significantly higher web speeds and, thus, increased output is achievable without detriment to the quality of the nonwoven web.

Patent CA-2125053-A1 (CA)
Title: Simultaneous analog and digital communication
Inventor: BREMER GORDON
IPC: H04J7/00
Filed: 1994-06-03
Abstract: CONTROLLLED SIMULTANEOUS ANALOG AND DIGITAL COMMUNICATION Abstract A method and apparatus for control of concurrent communication of analog information and digital information. In general terms, when the communication channel is viewed as a multi-dimensional space, the digital information signal is divided into symbols, and the symbols are mapped onto the signal space with a preset distance between them. The analog signal, generally limited in magnitude to less than the distance separating the symbols, is converted to component signals and added (i.e., vector addition) to the symbols. The sum signal is then transmitted to the receiver where the symbols are detected and subtracted from the received signal to yield the analog signal components. The transmitted analog signal is recreated from those components. Both half-duplex and full-duplex operation is available in accordance with this invention. The illustrative embodiment includes control means that is sensitive to input signals applied to the modem disclosed herein. To wit, the control is sensitive to signals from the analog port, signals from the digital port, and signals from the port that carries the combined digital and analog signals. Operation of the near-end modem is controlled as well as operation of the far-end modem.

Abstract: ABSTRACT OF THE DISCLOSURE          Disclosed is a compressor having a plate rotatable about an axis of a rotary shaft and a piston connected to the plate.          The plate causes the piston to reciprocate between a top dead center and a bottom dead center in accordance with the rotation movement of the plate.  Cam surfaces are provided with the plate for actuating the piston.  The cam surfaces have first portions for driving the piston toward the top dead center, and second portions for driving the piston toward the bottom dead center.  Transmission members are interposed between the piston and the plate for transmitting the rotation movement of the plate to the piston.  The first and second portions cause the transmission members to displace on the cam surfaces.  At least one of the first and second portions are arranged to have a normal line extending obliquely to the axis of the rotary shaft for a constant contact between the transmission members and the one of the portions.

Patent CA-2136416-A1 (CA)
Title: System for measuring proteolytic activity of periodontopathogenic bacteria
Inventor: LOESCHE WALTER J
IPC: C12Q1/02
Filed: 1992-05-22
Abstract: 2136416 9324651 PCTABScor01 A colorimetric assay detects the presence of proteolytic activity in a specimen of subgingival plaque, for example, with a chromogenic test substance which is hydrolyzed by trypsin-like enzymes produced by periodontopathogenic bacteria in the specimen to release a chromophore. Release of the chromophore is associated with a visible color change and is indicative of the presence of periodontal disease. The results of this chromogenic assay for proteolytic activity are reliable provided at least a minimum number of microorganisms, on the order of 1,000,000 to 10,000,000, are present in the specimen. The colorimetric assay of the present invention indicates whether the specimen includes the requisite number of microorganisms so that false negative results are not occasioned as a result of inadequate specimen size. A nonspecific marker of enzymatic activity of microorganisms in the specimen, illustratively phosphatase or peptidase enzymes, indicates specimen size sufficiency by the release of a chromophore from a nonspecific chromogenic test substance, in response to the nonspecific enzymatic activity.

Abstract: The present invention provides an apparatus and method for forming a composite web having selected discrete pocket regions which are distributed on a carrier layer and contain high-absorbency material. The invention includes a pattern chamber having opposed side walls, an entrance end wall and an exit end wall. A particulate supplying mechanism provides particles of high-absorbency material into the pattern chamber, and a web supplying mechanism provides a gas permeable carrier layer. A foraminous forming mechanism moves the carrier layer through the pattern chamber, and the forming mechanism includes a pattern of openings which are formed therethrough and are arranged to provide for a selected pattern of the discrete pocket regions. A vacuum supplying mechanism provides a selected level of relatively low gas pressure at an underside region of the forming mechanism to produce a selected gas-flow through the carrier layer and the foraminous forming mechanism to form the pocket regions. A covering mechanism provides a layer of liquid-permeable covering material to sandwich said pocket regions of high-absorbency material between said carrier layer and said covering layer.

Patent CA-2153985-A1 (CA)
Title: Water stream and laser beam fracturing apparatus
Inventor: SELLAR JOHN G
IPC: B28D1/22
Filed: 1994-01-12
Abstract: The present invention is a novel apparatus (15) for excavating a mass (19) such as a rock (21). The present invention directs a high velocity fluid stream (14) onto a mass and simultaneously directs a pulsing laser beam (17) onto the same mass. The laser beam (referred to as the "fracturing laser beam") vaporizes material and the fluid confines the vaporized material causing shock waves to enter the rock. The confined shock waves impart greater force than non-confined shock waves and this greater force fractures the mass. The fluid stream also washes loose particles from the mass to provide a new excavation surface.
