Patent CA-2144888-A1 (CA)
Inventor: ROTH ELDON
IPC: A23L3/015
Filed: 1995-03-17
Abstract: An apparatus for improving the quality of a foodstuff includes a container for containing the foodstuff to be processed and a working gas under an operating pressure. A compressing device places the working gas and the foodstuff under the desired operating pressure and this operating pressure is held for an operating period. The apparatus also includes an arrangement for releasing the operating pressure, preferably suddenly, allowing the foodstuff and any residual gas to go to a relatively lower pressure, which may be atmospheric pressure or a vacuum. This pressurization, hold, and pressure release cycle improves foodstuff quality by reducing undesirable microbe content. Also, the pressurization, hold, and release cycle improves color in meats.

Title: Glass bottle pulverizing method and apparatus
Inventor: LUKAS DONALD E
IPC: B02C19/00
Filed: 1993-12-08
Abstract: The present invention is a method and apparatus for pulverizing empty glass bottles into small fragments of a predetermined maximum size to reduce greatly the storage and handling problems associated in the past with empty bottles. The apparatus comprises a cabinet (11) having a vertical passageway (17) through which bottles are delivered to a pulverizing station (36) where the bottles are smashed into small fragments. The pulverizing station includes a spinning metal pulverizing blade (37) surrounded and partially enclosed by a tapered metal cowl (38). The spinning blade and cowl together ensure that bottles are pulverized completely and into fragments of at most a predetermined maximum size before being deposited into a receptacle (43) that underlies the pulverizing station. Split rubber diaphragms (17, 48 and 49) and a brush filter (67) are disposed along the length of the passageway and prevent the escape of glass fragments and glass dust through the passageway and into the atmosphere.

Abstract: A shielded needle assembly includes an elongate needle having a pointed distal end, a proximal end and a passageway therethrough. The assembly further includes a hub having an opening for receiving the needle so that said distal end of said needle projects outwardly, and has elements for releasably mounting the hub on a fluid handling device. The assembly has a shield having an open end, a closed end, a sidewall having a slot extending from the open end toward the closed end, and an arm extending radially outwardly at the open end opposite the slot. The shield has a first position at which the needle is exposed for use and a second position at which the shield substantially obstructs access to the needle. The slot provides clearance for the needle. A mounting rotatably holds the shield onto the hub. The mounting has a first pivot for pivotally attaching the shield to the mounting at the arm. The mounting further includes a second pivot having activating elements pivotally attached for interacting with the arm so that movement of the activating elements about the second pivot by the user causes movement of the shield from the first position toward the second position.

Patent CA-2162182-A1 (CA)
Inventor: CHLUS MAREK
IPC: E04C3/07
Filed: 1995-11-06
Abstract: To construct a section of wall, the studs are seated perpendicular to a track at either 16-inch or 24-inch so that an indentation in the side of the track fits precisely into the corresponding indentation in the side of the stud.  If the studs are placed at 16-inch intervals, every third stud will have a corresponding indentation from the track on each side, whereas the others will have only one side with an indentation from the track.  The studs cannot slide out of position because of the match-up of the indentations, and another track will extend across the tops of the studs with exactly the same match-up of indentations, so the only studs that need be screwed to the tracks are the end studs of the section.  Self-tapping screws would be used.    The two features of Easy Stud that make the construction easier, faster and more precise are the indentations requiring no preliminary measuring or marking and the fact that only the end studs need be fastened by screws.    It should be noted, however, that the basic form and function of this invention may be varied or modified so that the application and use of Easy Stud could be broader than originally envisioned.

Patent CA-2175886-A1 (CA)
Title: Optical Wavelength Division Multiplexer Device
Inventor: MUGINO AKIRA
IPC: G02B6/12
Filed: 1996-05-06
Abstract: The present invention proposes an optical wavelength division multiplexer device which has low through loss and low reflection loss, and also has high isolation. A filter member is made up from a filter base board upon which is formed a wavelength division filter 5, and is disposed so as to intersect an input and output optical waveguide 3 of rectilinear form part-way along it at an intersection angle .alpha.. When light which includes light of two different wavelengths .lambda.1 and .lambda.2 is incident through an incident light side of the input and output optical waveguide 3, the light of wavelength .lambda.2 passes through the wavelength division filter 5 and is emitted through an emitted light side, while the light of wavelength .lambda.1 is reflected by the wavelength division filter 5 in a direction separated from the input and output optical waveguide 3. A reflected light reception waveguide 1 is formed as rectilinear and is arranged in this reflection direction so as to receive the reflected light, with a gap being left between this reflected light reception waveguide 1 and the input and output optical waveguide 3, and the reflected light of wavelength .lambda.1 is received into a reflected light reception end thereof and is emitted from a received light after end portion thereof. By providing this gap between the input and output optical waveguide 3 and the reflected light reception waveguide 1, increase of loss due to mutual action between the incident light and the reflected light is restrained.

IPC: G06F3/01
Filed: 1996-06-20
Abstract: Words can be entered into a computer character by character using sign language by a pair of gloves having electrodes disposed on their surfaces.  When a sign is made, circuits are established between various combinations of electrodes which uniquely identify the sign being made.            Signs are read out using a hand tapper comprising a plate having a hand-shaped recess on its surface.  Solenoids having tapper pins are disposed beneath the bottom of the recess and at the sides of the recess to allow the hand to be stimulated on its front and sides, thereby producing the sensation of being signed on by another person.            The gloves and tapper can be used in a tactile telephone which allows communication between deaf and blind persons, for data entry and read-out, and for allowing deaf blind access to literature via electronic media, such as computer discs or e-mail.

Filed: 1996-09-27
Abstract: The invention relates to diagnostic methods for determining the genotoxic state or phenotype of a specimen by analyzing its nuclear DNA through spectral analysis. In combination with the discovery that there is a non-random progression of structural alterations of nuclear DNA from a healthy or non-genotoxic state to a carcinomicstate and further to a metastatic state (both genotoxic states), a comparison between a specimens' nuclear DNA obtained by spectral analysis to a reference spectra will yield a state genotoxic state determination based upon a specimen's nuclear DNA phenotype, irrespective of histological evidence of neoplasia or other aberrant cellular reproduction such as cancer or metastasis.
