Patent CA-2158984-A1 (CA)
Inventor: GUPTA PRAMOD K
IPC: C12N5/00
Filed: 1995-02-23
Abstract: The invention is a method for reproducing Douglas-fir by somatic embryogenesis using plant tissue culture techniques in a multistage culturing process. A suitable explant, typically the fertilized embryo excised from an immature seed, is first cultured on a medium that induces multiple early stage embryos. These are multiplied in a second culture having reduced growth hormones where the early stage embryos grow in size and vigor to advanced early stage embryos. The embryos may then be transferred direclty to a cotyledonary embryo development culture containing an adsorbent such as activated charcoal.  Preferably, they are first singulated by shaking in two or more liquid subcultures containing the adsorbent prior to placing them on the development medium. After several weeks somatic embryos having the appearance of zygotic embryos will have formed. These may be germinated before or after storage and transplanted to soil for further growth.

Title: A Method of Forming a Tissue Paper Web
Inventor: ERIKSON JAN A
IPC: D21F11/14
Filed: 1994-05-18
Abstract: A tissue web (W), which has improved formation and improved tensile properties but no appreciable deterioration of retention and layer purity, if applicable, in comparison with tissue webs produced in conventional twin wire tissue formers, may be formed in a roll type twin wire former by draining 90-99 %, preferably 98-99 %, of all drainable water from the slurry while on the forming roll (1), preferably a suction forming roll, the remaining 1-10 %, preferably 1-2 %, of the drainable water being sufficient to have a substantial amount of the papermaking fibers free in the slurry during an initial phase of a subsequent step, and downstream of said forming roll (1), draining said remaining 1-10 %, preferably 1-2 %, from the slurry while vibrating the slurry sufficiently to create a micro-turbulence causing a small scale agitation of the fibers to prevent them from forming any appreciable fibrous web (W) on the two forming fabrics (3; 4) until the water remaining in the slurry is insufficient for allowing the fibers to substantially change their position relative to one another.  The vibration frequency is at least 100 Hz, and the vibrations may be provided by a multiblade hydrofoil (7).

Title: Burst excited linear prediction
Inventor: GARDNER WILLIAM R
IPC: G10L19/00
Filed: 1995-02-01
Abstract: A novel and improved apparatus for encoding a signal which is bursty in nature. In a code excited linear prediction algorithm, short term redundancies are removed by formant synthesis filter (6) and long term redundancies are removed by pitch synthesis filter (4) from digitally sampled speech, and the residual signal which is bursty in nature must be encoded. The residual signal is encoded using three parameters a burst shape index corresponding to a burst shape provided by burst element (10), a burst gain which scales the burst shape through scalar multiplication in multiplier (14), and a burst location value which determines the temporal location of the scaled burst in variable delay element (16). Together the three parameters specify a waveform to match the residual signal. Further disclosed is a closed loop exhaustive search method by which to find the best match to the residual waveform and a partially open loop method wherein the burst location is determined by an open loop analysis of the residual waveform, and the burst shape and gain parameters are determined in a closed loop fashion. The matching operations are performed by minimizing the mean squared error (MSE) using summing element (18), energy computation element (20) and minimization element (22).

Title: Method of forming a metal-to-metal seal in high pressure applications with low contact stress
Inventor: SLACK MAURICE
IPC: F16L27/12
Filed: 1996-09-05
Abstract: A method of forming a metal-to-metal seal in high pressure applications with low contact stress. Firstly, providing a first elongate pressure containment member having a surface of revolution. Secondly, providing a second elongate pressure containment member having an exterior surface, an interior surface, a remote end, and a thin walled extension sleeve having a first end and a second end. The first end of the thin walled extension sleeve is conjoined with the second elongate pressure member at the remote end.      The second elongate pressure containment member is of a greater thickness than the sleeve. Thirdly, coupling the first elongate pressure containment member and the second elongate pressure containment member with the sleeve positioned in close relation to the surface of revolution.      Fourthly, placing the first elongate pressure containment member and the second elongate pressure containment member in an environment in which fluid pressure tends to cause a flow of fluids from the second end to the first end of the sleeve along an interfacial region between the sleeve and the surface of revolution. Fluid pressure tends to constrict and set up a pressure gradient which promotes sealing along the interfacial region.

Abstract: An apparatus for separating and supporting an article from a base surface includes at least one spacer having a first surface engageable with the base surface, a second surface spaced from the first surface and engageable with the article to be supported, and a third surface extending between the first and second surfaces. The third surface defines coupling members or portions for releasibly interlocking adjacent spacers with respect to one another.  The second surface can be defined by at least one elongated member having opposite ends formed to allow interconnection between identical spacers.  The interconnection between the spacers can be accomplished by one end of the elongated member including a coupling member and the opposite end having a mating receiving member.  An integral pedestal portion can be of sufficient length to separate the second surface and the article to be supported from any undesirable substance that is located on the base surface.  The effective size of the second surface defined by the interlocking spacers may be varied by adding or removing individual spacers allowing substantially abutting engagement of the interconnected spacers against any confining surfaces.
