Patent CA-2219053-C (CA)
Title: Apparatus and method for separating solids from drilling fluids
Inventor: KING DAVID
IPC: B01D21/00
Filed: 1997-10-22
Granted: 1999-05-25
Abstract: A solids separation system may be used to separate solids, such as cuttings from drilling fluids used in well drilling operations. The system includes a settling tank having transverse baffles defining a fluid receiving chamber, a fluid output chamber and one or more intermediate chambers. Fluid introduced into the fluid receiving chamber can flow in a sinuous path through apertures in the baffles to the fluid output chamber. Solids settle to the bottom of the settling tank. A material conveyor, preferably an auger, extends along a bottom surface of the settling tank to an outlet port in the fluid receiving chamber. A centrifuge is connected to the output port to receive fluid in which solids have been concentrated. Fluid output from the centrifuge is reintroduced into the settling tank. The apparatus and method of the invention permit a single centrifuge to be used to handle a higher volume of fluid than is possible with conventional methods and apparatus. This provides significant cost savings.

Title: Actuator for accomplishing the swinging motion of a swinging arm
Inventor: PAAKKUNAINEN MARKO
IPC: F15B11/20
Filed: 1997-09-25
Granted: 2006-07-11
Abstract: An actuator particularly for accomplishing the swinging motion of a swinging arm comprises two cylinders (S, S') using a pressurized medium, the piston rods (8, 8') of the cylinders being connected to a structure rotatable in relation to the swinging arm for the purpose of rotating the swinging arm around a rotation axis (A) by the effect of movements of the pistons (7, 7') of the cylinders. The actuator comprises two control valves, of which one control valve (2) is arranged to guide the pressurized medium either to both cylinders (S, S') while they are coupled in parallel, or solely to one cylinder (S, S') where its piston rod chamber (10, 10') and piston chamber (9, 9') are coupled together. This results in a movement of the piston outwards, because the pressure is directed to the whole work area of the piston (7, 7') on the side of the piston chamber (9, 9') and on the side of the piston rod chamber only to the work area which is the difference between the cross-sectional areas of the piston (7, 7') and the piston rod (8, 8'). Further, the pressurized medium needs to be supplied only in an amount proportional to said difference for achieving the same speeds of motion as before.

Abstract: A method and system for inhibiting the counterfeiting of electronic cash smart cards (11) that use microchips for monetary stored value. Such cards have recently been counterfeited by the use of electronic techniques to break the security codes. Such counterfeiting can be inhibited by bonding (Fig. 3) an optical memory stripe (17; 41; 74) to the smart card with pre-recorded or post-recorded validation data (19) on the cards (Fig. 1). This optical validation data would be read (Fig. 2) with a photodetector array (65) and could be transmitted to the recipient during funds transfer and/or used locally to control dispensing of cash. Thus, successful counterfeiting of the modified electronic cash card would require meeting exacting electronic and optical requirements.

Abstract: In an Asymmetric Digital Subscriber Loop (ADSL) Discrete Multi-Tone (DMT) system, ADSL DMT equipment includes an encoder that operates on a DMT input signal representing f symbols/sec. to generate, for transmission, a DMT output signal representing Nf symbols/sec., where N > l, and where each symbol from the DMT  input signal is generated in a redundant form in the DMT output signal. In one example of a redundant form, each symbol from the DMT input signal is repeated in N  consecutive symbol intervals in the DMT output signal. In another example of a redundant form, every N DMT input symbol values are transmitted in 2N consecutive symbol intervals in the DMT output signal. These 2N consecutive symbols in the DMT output signal include 1) N symbols whose values equal the respective N DMT input symbol values and 2) N symbols whose values are a function of the respective N DMT input symbol values.

Patent CA-2280811-C (CA)
Inventor: KOMORIYA AKIRA
IPC: G01N33/573
Filed: 1998-02-20
Granted: 2015-11-03
Abstract: The present invention provides for novel reagents whose fluorescence increases in the presence of particular proteases. The reagents comprise a characteristically folded peptide backbone each end of which is conjugated to a fluorophore. When the folded peptide is cleaved, as by digestion with a protease, the fluorophores provide a high intensity fluorescent signal at a visible wavelength. Because of their high fluorescence signal in the visible wavelengths, these protease indicators are particularly well suited for detection of protease activity in biological samples, in particular in frozen tissue sections. Thus this invention also provides for methods of detecting protease activity in situ in frozen sections.

Abstract: Adsorption of carbon dioxide from gas streams at temperatures in the range of 300 to 500 °C is carried out with a solid adsorbent containing magnesium oxide, preferably promoted with an alkali metal carbonate or bicarbonate so that the atomic ratio of alkali metal to magnesium is in the range of 0.006 to 2.60. Preferred adsorbents are made from the precipitate formed on addition of alkali metal and carbonate ions to an aqueous solution of a magnesium salt. Atomic ratios of alkali metal to magnesium can be adjusted by washing the precipitate with water. Low surface area adsorbents can be made by dehydration and CO2 removal of magnesium hydroxycarbonate, with or without alkali metal promotion. The process is especially valuable in pressure swing adsorption operations.

Title: Spring rate balancing of the flow tube and a balance bar in a straight tube coriolis flowmeter
Inventor: VAN CLEVE CRAIG BRAINERD
IPC: G01F1/84
Filed: 1999-02-05
Granted: 2003-06-17
Abstract: A Coriolis flowmeter having a single straight flow tube, a balance bar parallel to said flow tube, a brace bar connecting ends of the balance bar t o the flow tube and to a surrounding case. Improved dynamic balance of the flowmeter is maintained in response to changes in density of the flowing material by reducing the spring function of the balance bar and/or the flow tube. This concentrates the spring function of the flowmeter in the brace ba r structure. A vibrational node in the brace bar structure separates the effective spring function of the balance bar from the effective spring function of the flow tube. The vibrational node moves within the brace bar i n response to materials of different densities in the flow tube at different times. This nodal movement changes the ratio of the effective balance bar spring function to that of the effective flow tube spring function to mainta in improved dynamic vibrational balance of the flowmeter without involving the case mass.

Abstract: L'invention concerne un procédé et un appareil de mise en valeur de texte servant à une présentation de textes qui facilite la lecture par un humain. Le procédé consiste à extraire d'un texte lisible par machine des attributs spécifiques au texte et à modifier la présentation du texte en fonction de ces attributs. Le mode de réalisation préféré de ce procédé consiste en ce qui suit: extraire à partir d'une phrase des parties du discours et la ponctuation; appliquer des règles de pliage utilisant les parties du discours pour déterminer les points de pliage et; présenter chacun des segments du texte à la ligne, avec un décalage horizontal déterminé qui est basé sur les attributs spécifiques au texte. Selon l'un des procédés, le texte affiché suit des courbes dont la forme dépend du contenu. Selon un autre procédé, les emplacements relatifs du texte sont affichés à l'intérieur d'une hiérarchie, au moyen de plans alternants inclinés horizontalement et verticalement. Un troisième procédé permet de lire des segments du texte à travers les pages opposées sans avoir à attendre que la pagination se fasse. Un quatrième procédé prévoit l'affichage du texte que l'on peut lire du bas vers le haut comme s'il était lu depuis la partie avant vers la partie arrière. Enfin, un des procédés permet d'afficher les mots en utilisant des couleurs qui reflètent les rapports entre, d'une part, les mots et, d'autre part, les segments du texte dont ils sont éloignés.
