Title: A low-density and low-porosity cementing slurry for oil wells
Inventor: DROCHON BRUNO
IPC: C04B28/08
Filed: 2000-07-06
Abstract: The invention relates to a cement slurry for cementing an oil well or the like, the slurry having a density lying in the range 0.9 g/cm3 to 1.3 g/cm3, and being constituted by a solid fraction and a liquid fraction, having porosity (ratio of liquid fraction volume over total volume) lying in the range 38% to 50%. The solid fraction is constituted by a mixture of lightweight particles, microcement and optionally Portland cement and gypsum. Such cements have remarkable mechanical properties due to their very low porosity in spite of having very low density.

Title: Self-cooling can
Inventor: SPOTTISWOODE MICHAEL STEPHANE
IPC: F25D3/10
Filed: 2000-08-02
Abstract: A self-cooling can (10) comprising an evaporator unit (30) within the can (10) and an absorber unit (20) provided outside the container body (10). A beverage within the can (10) is cooled by means of vapour which passes from the evaporator (30) to the absorber (20) when these are connected so as to provide a vapour path between the two.  The path for water vapour, for example, to pass from the evaporator (30) to the absorber (20) is formed by rupturing a panel (40) between evaporator (30) and the absorber (20) when the can (10) and part or all of the absorber (20) are rotated relative to each other.

Title: A method for generating gray scale transfer functions for use in displaying a digital radiogram
Inventor: BELL JEFFREY H
IPC: H04N1/407
Filed: 2000-11-10
Abstract: A method for generating on demand a gray scale transfer curve for use in displaying an image comprised of plurality of digital values representing pixel gray scale levels with a desired contrast and brightness (Fig. 3). This is achieved by using a single sigmoid shaped function Y=f(X,a,b,c) representing an H & D curve of a photographic film. The Y axis represents digital output values to be used in displaying an image (Fig.2), while the X  axis represents input digital values representing captured image information (Fig. 2). "a" is a number representing boundary conditions for X and Y, "b" is a first parameter controlling the location of the curve along the X axis and "c" is a second parameter controlling the slope of the curve slope. This function is used to derive a Look-Up-Table (LUT) representing a continuous GST  curve having the desired contrast and brightness.

Title: Method for diagnosing immunologic food sensitivity
Inventor: FINE KENNETH D
IPC: G01N33/564
Filed: 2001-03-13
Abstract: The invention includes novel methodology for diagnosing immunologic food or drug sensitivities. The method for diagnosing food sensitivities includes using diagnoses of other related disorders, such as microscopic colitis or other chronic immunologic/autoimmune syndromes, chronic diarrhea, irritable bowel syndrome, and hepatitis C and other hepatic diseases, Crohn's disease, alcoholism, and other idiopathic neuropsychiatric and neurologic disorders, as indicators in the diagnosis of the food sensitivity.  Additionally, failure to respond to or a relapse after treatment for microscopic colitis with bismuth subsalicylate is disclosed by the present invention as being a further indicator in the diagnosis of immunologic food sensitivity. Finally, the presence of certain HLA-DQ alleles, particularly HLA-DQ1,3; -DQ1,7; -DQ1,8; and -DQ1,9, HLA-DQ1,1, and at least two subtypes of the HLA-DQ1 allele identified by molecular analysis as HLA-DQB1*0501 and HLA-DQB1*0602, as indicators in diagnosing immunologic food sensitivity, particularly gluten sensitivity or celiac sprue, and in diagnosing the related disease of microscopic colitis and other autoimmune disorders is also disclosed by the invention. A method for food sensitivity panel testing (for sensitivities other than gluten sensitivity) by detecting IgA antibodies in serum is also disclosed. A method for testing stool samples for the presence of particular antibodies, which is more sensitive and less invasive than prior art testing methods, is also disclosed for diagnosing immunologic food sensitivities. These methods of diagnosis may be used alone or in combination to further enhance the accuracy of diagnosis.
Patent CA-2401930-A1 (CA)
Title: Frame straightening apparatus
Inventor: LINQUIST SCOTT ALLAN
IPC: B21D1/12
Filed: 2002-09-09
Abstract: A frame straightening apparatus is disclosed, using vertical posts positioned under the vehicle to push outward to straighten deformities in the frame. The apparatus is lightweight, strong and easily configurable from beside the vehicle under repair, without requiring increased ground clearance. The apparatus comprises a pair of floor rails bolted to, embedded within or forming part of the floor of the repair facility. The top of each floor rail has a partially closed channel into which a series of bolts can be inserted and slid longitudinally along the rail. The bolts can be used to quickly fasten and adjust a transverse U-shaped pushing rail and one or more transverse holding rails. The pushing rail has a series of bores along each leg, to which a U-shaped pivot base may be attached using pins. The pivot base is short enough to clear the undercarriage of a vehicle under repair positioned over the floor rails. A pushing post may then be positioned into place and quickly fastened into place at the top of the pivot base using pins. The pushing post pivots about the pivot base and, under the force of a ram assembly attached at the other end to the pushing rail, can apply pushing pressure on the frame of the vehicle under repair. Each holding rail permits a sliding post to slide along its length. One of the sliding posts may conveniently be short enough to clear the undercarriage of the vehicle under repair. A holding post may be positioned into place and quickly fastened into place at the top of the sliding post using pins. The holding post grips the exterior of the vehicle frame and is held in position by a chain attached at its other end to the holding rail. Diamond repairs may be effected using a set of diamond rails comparable to and abutting the floor rails in a transverse direction. Minor downward frame pulling repairs may be effected by the use of a pulley assembly attached to the pushing rail and a chain assembly. The apparatus may be conveniently mounted onto the bed of a towed platform to permit remote repairs.

Inventor: GO CARLOS
IPC: H04R7/02
Filed: 2002-09-27
Abstract: A flat panel sound radiator having improved audio performance is provided. The sound radiator has a panel to which is coupled a traditional electro-mechanical exciter for imparting audio frequency vibrational energy to the panel.      The panel has a honeycomb core made of Kraft paper, which is flexible, has a low self noise, and high noise damping characteristics. The core is sandwiched between facing skins made of a material with a high Young's modulus, a high tan delta, a high tensile strength, and low self noise.      Preferably, this material is an aramid polyamide such as Kevlar®, Nomex®, Conex®, or Technora®, all of which exhibit these properties. The facing skins are fixed to the core with an adhesive that is flexible and has high acoustic damping qualities and high shock resistance, such as rubber cements, silicone adhesives, and water-based acrylic adhesives. The result of the combination of these materials with their respective properties is a flat panel sound radiator that exhibits signal-to-noise greater than 40dB for an 85dB input signal within key audio frequency ranges, which is 20 dB or more greater than prior art flat panel sound radiators. Base response and sound level capacity are also dramatically enhanced.

Abstract: A mass spectrometer is disclosed wherein a z-lens 4 upstream of an orthogonal acceleration Time of Flight mass analyser 9 is repeatedly switched between a first mode wherein ions are transmitted to the mass analyser 9 for subsequent mass analysis with a relatively high transmission and a second mode wherein ions are transmitted with a relatively low transmission. If it is determined that mass spectral data obtained when the mass analyser 9 is in the first mode is suffering from saturation, then suitably scaled mass spectral data obtained when the mass analyser 9 is in the second mode is used instead. If the saturation is severe then the mass spectral data obtained in the first mode may be replaced in its entirety with mass spectral data obtained in the second mode.
