Title: Open steel cord structure
Inventor: VAN GIEL FRANS
IPC: D07B1/06
Filed: 1994-12-09
Abstract: A steel cord (114) for the reinforcement of rubber products comprises strength elements (100, 132) and has length, a longitudinal central axis (112) and a cord pitch. Each of the elements (100) has a portion on a plane YZ perpendicular to the longitudinal central axis (112). At least one of these projections takes the form of a curve with a radius of curvature which alternates between a maximum and minimum. The curve further has a center of curvature. The radius of curvature and the center of curvature lie inside the curve so that a convex curve is obtained. The cord (114) is further characterized by one or both of the following features: (i) the distance between two minimum radii of curvature of said curve measured along the longitudinal central axis (112) is different from half the cord pitch; or (ii) if all of said elements (100) provide a convex curve, at least one of said convex curves substantially differs from another convex curve. The steel cord (114) allows full rubber penetration despite low values of cord diameter and part load elongation (PLE).

Title: Cemented carbide articles and master alloy composition
Inventor: MCCANDLISH LARRY E
IPC: B22F9/02
Filed: 1996-08-23
Abstract: A low melting point alloy is used to sinter metal carbide particles. The alloy is a eutectic-like alloy formed from a binding metal such as iron, cobalt or nickel, in combination with vanadium and chromium. The alloy is preferably formed by forming two separate alloys and blending these together. The first alloy is formed by spray drying together a solution of a binding metal salt such as a cobalt salt with a solution of a chromium salt. The formed particles are then carburized to form a cobalt-chromium-carbon alloy. A separate vanadium alloy is formed in the same manner. The two are combined to establish the amount of chromium and vanadium desired, and this, in turn, is used to sinter metal carbide parts. This permits sintering of the metal carbide parts at temperatures less than 1250° C and in turn significantly inhibits grain grown without a significant decrease in toughness. It is particularly adapted to form carbide products wherein the carbide grain size is as low as 120 nanometers.

Patent CA-2186833-A1 (CA)
Inventor: GIJZEN MARK
IPC: C12N15/82
Filed: 1996-09-30
Abstract: A novel seed coat specific peroxidase genomic sequence is characterized and presented. Adjacent DNA regulatory regions have also been characterized. The seed coat peroxidase is translated as a 352 amino acid precursor protein of 38 kDa comprising a 26 amino acid signal sequence which when cleaved results in a 35 kDa protein. Plants containing a dominant Ep allele accumulate large amounts of peroxidase in the hourglass cells of the subepidermis. Homozygous recessive epepgenotypes do not accumulate peroxidase in the hourglass cells and are much reduced in total seed coat peroxidase activity. Probes derived from the cDNA, or genomicDNA can be used to detect polymorphisms that distinguished EpEp and epep genotypes. Cosegregation of the polymorphisms in an F2 population from a cross of EpEp and epep plants shows that the Ep locus encodes the seed coat peroxidase protein. Comparison of Ep and ep alleles indicates that the recessive gene lacks 87 bp of sequence encompassing the translation start codon. The heterologous expression, as well as vectors and hosts to be used for the expression of the seed coat peroxidase, are also disclosed. The seed-specific DNA regulatory region maybe used to control expression of genes of interest such as i) genes encoding herbicide resistance, or ii) biological control of insects or pathogens (e,g, B.thuringiensis), or iii) viral coat proteins to protect against viral infections, or iv) proteins of commercial interest (e.g. pharmaceutical), and v) proteins that alter the nutritive value, taste, or processing of seeds.

Filed: 1997-01-03
Abstract: In a foam or board insulated building panel with a structural frame, perimeter and interior frame members are composed of two separate structural shapes thermally separated by the insulation so that neither shape penetrates the full panel width, to reduce the conduction of heat or cold through the panel. Varying panel thicknesses can be achieved using the same dimensioned shapes by varying the separation dimension between them.

Abstract: An ultrasonic continuous wave doppler blood flow-meter deflects an ultrasonic continuous wave to an arbitrary angle and transmits it into an organism, thereby measuring a blood flow speed of the organism.          Two continuous sine wave signals of different phases and a plurality of sets of pairs of coefficients are generated.  One of each of the pairs of coefficients is multiplied to one of the two sine wave signals.  The other one of each of the pairs of coefficients is multiplied to the other one of the two sine wave coefficients. After that, two sine wave signals after the multiplication are added, so that a plurality of synthesis sine wave signals are generated.  When a plurality of micro vibrators are driven by the plurality of synthesis sine wave signals, the ultrasonic continuous wave is deflected to an arbitrary angle and is transmitted into the organism.

Title: Process and device for measuring an alternating electric current with temperature compensation
Inventor: BOSSELMANN THOMAS
IPC: G01R15/24
Filed: 1995-08-25
Abstract: After passing through a Faraday sensor device (3), linearly polarised measuring light (L) is broken down in an analyser (7) into two diffently polarised partial light signals (L1, L2). The intensity of the corresponding electric signals (I1, I2) is normal by dividing their alternating signal component by their direct signal component. A measuring signal S =  (2*S1*S2)/((S2-S1)+K*(S1+S2)) is derived from the two normalised intensity signals, in which cos(2.theta.+2)=-2/(3K) and sin(2.theta.-2)=1 stand for a correction factor K, an injection angle  between the polarisation plane of the injected measurement light (L) and a proper axis of the linear double-fraction in the sensor device (3) and a decoupling angle .theta. between this proper axis and a natural axis of the analyser (7).

Title: Fuel-fired modulating furnace calibration apparatus and methods
Inventor: MAIELLO DENNIS R
IPC: F23N5/02
Filed: 1997-04-09
Abstract: A gas-fired air heating furnace has a modulatable supply air blower and a modulatable gas valve operatively connected to the combustion air heat exchanger burner.  A calibration sequence of a microprocessor-based control system is utilized to automatically determine the precise relationship between the gas valve setting and the actual heat transferred by the heat exchanger to air flowing through the furnace by measuring the actual air temperature rise across the heat exchanger obtained using initial calibration settings of the blower and gas valve.  The microprocessor uses the results of its calibration sequence to establish an adjustment correlation between the blower and gas valve settings which the microprocessor subsequently utilizes to adjust the flow rates of the blower and the gas valve in a manner maintaining a predetermined, generally constant air temperature rise across the heat exchanger while the furnace alters its overall air heating output rate in response to changing heating demands from the conditioned space served by the furnace.
