Patent CA-2099505-A1 (CA)
Inventor: NELSON TERENCE J
IPC: H04N7/15
Filed: 1992-01-13
Abstract: Apparatus (500) establishes eye contact between communicating parties during video conferencing and comprises mirrors, polarizers and a camera which are positioned such that the apparatus protrudes a minimal distance from the terminal screen (125). A first polarizer (511) located in front of the terminal screen passes a polarization of the image of the distant party radiated from the terminal screen. A first mirror (521), which is partially silvered, reflects the image of the local party and transmits the image of the distant party. The reflected image of the local party is directed toward a second mirror (522) located below the first mirror. The second mirror is positioned to capture the image of the local party from the first mirror and to reflect this image into a miniature camera (530). A second polarizer (512) is located between the second mirror and the camera is cross-polarized with the first polarizer.

Title: Sealing element for inflatable packer
Inventor: ESLINGER DAVID M
IPC: E21B33/127
Filed: 1993-11-15
Abstract: ABSTRACT The  outer,  sealing  cover  of  an  inflatable  packer comprises an alternating series of thick and thin annular portions which act to effect greater sealing stresses and to inhibit the propagation of cracks or tears in the elastomeric cover.   Bonding with only portions of the underlying slats as well as a tapered contour and spacing from an end fitting act to help to retain the cover in its proper position during running and retrieval as well as decreasing the likelihood of the development of cracks and/or tears.

Title: Clarifying suspended solids from liquid process streams
Inventor: CHAMBLEE J WAYNE
IPC: B03D1/02
Filed: 1993-09-09
Abstract: ABSTRACT OF THE DISCLOSURE      Liquid process streams -- such as white water, pressate, or washer filtrate from a pulp and paper mill --are clarified in an efficient manner using a gas sparged hydrocyclone, which takes up a minimum of floor space.  A liquid stream having a consistency of less than about 0.5% solids is introduced into a first end of a vortex.  Gas is sparged into the liquid in the vortex to cause particles to attach to gas bubbles and move through a rejects outlet at the first end of the vortex, while clarified liquid is removed from a second end of the vortex.  A pedestal is typically provided at the accepts outlet, having a radial clearance with the inside of a porous tube through which the gas is sparged that is about 8-12% the radius of the porous tube.

Abstract: EXCAVATION MACHINE                    ABSTRACT An excavating machine having a cutter head which is provided with both reciprocating impact hammers and a static pick.  The impact hammers are mounted on either side of the static pick so as to flank this, and the tip of this can be extended or retracted relative to the tips of the hammers. The ripper pick can thus scarf out a mound of earth left between the two impact hammers, or can be extended to cut a channel into which the impact hammers then drive the adjacent material.  The impact hammers can be tilted relative to the axis of the ripper pick so that their tips either precede or follow that of the pick as they are moved across the working face.  The cutter assembly may be mounted to a tracked vehicle so as to extend forwardly from this for continuous mining, or laterally from this for long wall mining.
Patent CA-2108639-A1 (CA)
Inventor: TAKEUCHI HITOSHI
IPC: G11B5/00
Filed: 1993-10-18
Abstract: In a multi-track magnetic signal reproducing apparatus, a plurality of MR heads including MR (Magneto-Resistance Effect) elements are provided, corresponding to tracks on a magnetic tape. At the time of reproduction, constant current from a constant-current power supply is sequentially supplied, as a pulse-shaped current for detecting a signal, to each MR element by switching a switch in response to a prescribed clock signal. An output voltage from each MR element, related to reproduction of a magnetic signal on a corresponding track, is sequentially provided to one input side of a differential amplifier. In the differential amplifier, the offset voltage of each MR element provided to the other input side and the above-described output voltage are differentially amplified, and only voltage due to the reproducing magnetic signal of each track is accurately extracted. Accordingly, the supply of pulse-shaped current effectively suppresses an increase in the amount of consumption current regardless of the number of tracks on the tape (or the number of heads), and since the amplifier is shared between the tracks, the number of necessary terminals for such a multi-track MR head is reduced.

More specifically,  it has been discovered that the incorporation of at least 1 to 15 atomic percent of gallium and/or at least 1 to 15 atomic percent gold into stoichiometric copper germanide (Cu3Ge) compound results in a room temperature resistivity comparable to elemental copper, but with superior chemical and electronic stability upon exposure  to  air or  oxygen  at high temperatures. Furthermore,  the compounds of the present invention have none of the problems associated with the diffusion of copper into elemental and compound semiconductors which oftentimes lead to the degradation of the semiconductor device  characteristics.     Additionally,   the  present invention relates  to  a method  of preparing the novel compounds mentioned previously hereinabove.

IPC: E04F19/04
Filed: 1994-10-27
Abstract: The cove base is made from a relatively thin extruded  vinyl  and  has  a  height  dimension which  is substantially greater than the thickness. Although the cove base is used as a top set base and covers imperfections in the outer edges of floor tiles or the like, it has the appearance of a straight base in that it does not include a rounded toe.

A flexible projection which is a continuation of the front surface extends slightly downwardly and conforms to any high or low spots that may be in the flooring.  This projection also defines a space behind the projection and beneath the remaining parts of the cove base which may be used to contain a foam strip or caulking material. The cove base,  the foam strip and/or the caulking material may include an antimicrobial agent therein.

Abstract: Isolated 2-5A-dependent RNases, an interferon-induced enzyme which is activated by 5'-phosphorylated, 2',5'-linked oligoadenylates (2-5A) and implicated in both the molecular mechanisms of interferon action and in the fundamental control of RNA stability in mammalian cells (see Figs. 1 and 11), and encoding sequences therefor (see Figs. 3, 4, 9 and 10) are disclosed. The expression cloning and analysis of murine and human 2-5A-dependent RNases are also disclosed. Recombinant human 2-5A-dependent RNase produced in vitro and bound an activating affinity matrix, 2-5A-cellulose, have ribonuclease activity. The 2-5A binding properties of the recombinant and naturally occuring forms of 2-5A-dependent RNase are basically identical. Interferon induction of 2-5A-dependent RNase expression is demonstrated by measuring the mRNA levels in cells treated with interferon and cycloheximide. Analysis of aligned murine and human 2-5A-dependent RNase sequences revealed several features, including similarity to RNase E which is implicated in the control of mRNA stability in E. coli.
