Patent CA-2191145-C (CA)
Inventor: JOHANNESSON NEALE
IPC: F16L1/06
Filed: 1996-11-25
Granted: 2001-02-13
Abstract: A pipeline anchor apparatus  is disclosed.   The pipeline anchor apparatus provides left and right anchor units connected by a tie-down strap made of heavy-duty polyester or nylon webbing.   The strap prevents the pipeline from floating in wet conditions.  By flexibly conforming to the surface of the pipeline, the tie-down strap prevents denting of the pipeline which weakens the pipeline, contributing to pipeline bending.  Each anchor unit provides an helix anchor attached to an anchor rod that is buried deep in the soil.   The anchor rod is connected  to  an extension rod by means  of  a  lower coupling.  A tie-down bracket having a tubular body and a sleeve is carried by the extension rod.  Each end of the  tie-down  strap  is  attached to the  sleeve  of  a tie-down  bracket  of  an  anchor unit.    The  tie-down brackets may pivot about the extension rod to lessen stress as water forces the pipeline upwardly, against the tie-down strap.  The sleeve of the tie-down bracket is radially outwardly from the axis of the tubular body.  As a result, an upward force on the sleeve may force the tie-down  bracket  and  extension  rod  away  from  the pipeline, thereby protecting the pipeline from denting and bending.

Abstract: A laser ultrasonics technique (18) is used to characterize a composite dispersive response signal from a sample under analysis, such as a semiconductor wafer (16). Rather than measuring individual accoustic wa ve velocities at specific frequencies, an entire dispersive response signal (fig. 8) is analyzed. In a presently preferred embodiment of  this invention the entire dispersive response signal is analyzed using a wavelet-based technique (figs. 4a, 4b), such as dispersive wavelet transform analysis technique.

Title: Switched reluctance electric machine system
Inventor: BARNES MIKE
IPC: H02P25/08
Filed: 1996-07-04
Granted: 2006-09-05
Abstract: A switched reluctance electric machine system has an electric machine, a rechargeable DC energy store (7), principal voltage terminals (5, 6) and a controller. Where the machine is an electric motor, it is advantageous to be able to drive the motor from the DC energy store (7) as well as from an AC supply, and to recharge the energy store (7) from the AC supply. The charger which is needed for recharging is formed by a pair of closely-coupled coils (2, 3) forming windings for the machine, and a power converter (4) having a first circuit (9) containing a coil (2) and the principal voltage terminals (5, 6) and a second circuit (14) having a coil (3) and the DC energy store (7), each circuit (9, 14) including an electronic switching arrangement of a switch (12, 12') and a diode (13, 13') arranged in anti-parallel and connected in series with the coil (2, 3) to enable current to flow through each coil in either direction. The controller operates the switches (12, 12') of the converter (4) to provide a required operational mode, without needing manual re-configuration of the system. The charger is therefore formed from existing components, and the system as a whole has a flexibility, enabling the machine to act as a generator as well.

Abstract: An improved process for the purification of antibodies from human plasma or other sources is disclosed. The process involves suspension of the antibodies at pH 3.8 to 4.5 followed by addition of caprylic acid and a pH shift to pH 5.0 to 5.2. A precipitate of contaminating proteins, lipids and caprylate forms and is removed, while the majority of the antibodies remain in solution. Sodium caprylate is again added to a final concentration of not less than about 15 mM. This solution is incubated for 1 hour at 25°C to effect viral inactivation. A precipitate (mainly caprylate) is removed and the clear solution is diluted with purified water to reduce ionic strength. Anion exchange chromatography using two different resins is utilized to obtain an exceptionally pure IgG with subclass distribution similar to the starting distribution. The method maximizes yield and produces a gamma globulin with greater than 99% purity.

Abstract: Apparatus and method for the prevention of echo signals in terminals connected to a network carrying telephony traffic. The echo prevention occurs prior to the introduction of signal delay by a network. It provides a method of controlling echo contained in audio signals transmitted between the nodes of a network, wherein the audio signals experience delay in transit from node to node and wherein the echo controlling method is distributed across the nodes, the method comprising: a) feeding a signal from a local source of audio information to the node; b) canceling echo present in the local source signal to produce an echo canceled signal; c) suppressing any residual echo present in the echo canceled signal to produce an echo suppressed signal; and d) delivering the echo suppressed signal to the network.

Abstract: A limitation of a three-dimensional world in which objects in the distance may be represented in only two dimensions as a video on a screen occurs when a computer graphic object represented by computer graphics, e.g., in front of, to the side, above, or below the video screen, undergoes a trajectory that takes it to a location in the world that is not represented as computer graphics, but instead is within the field represented by the video, because such an object would disappear from view by the viewer. This limitation is overcome by having by determining when a computer graphic object undergoes a trajectory that takes it to a location in the world that is not represented as computer graphics, but instead is within the field represented by the video, and representing such an object as computer graphics in front of the screen to which at least one perspective transformation is applied, the perspective transformation being at least a function of the position at which the object is actually located.

Filed: 1998-05-04
Granted: 2007-04-17
Abstract: Novel starch-silicate adhesive compositions are disclosed which are of particular advantage in the manufacture of corrugated board. By the controlled combination of starch, alkali silicate and, optionally, caustic soda and borax it has been found possible to produce useable adhesives having much higher levels of solids content than conventional starch-based adhesives, thereby allowing for lowered energy costs in use of the adhesive formulation to manufacture boxboard, as well as improved product quality. The formulation of starch-silicate adhesives according to the invention allows viscosity, rheological characteristics - in particular gelation temperature - and the speed of "green-bond" formation to be controlled and adapted to the requirements of modern high-speed corrugating equipment.
