Patent CA-2218695-A1 (CA)
Title: Fuel injection device for internal combustion engines
Inventor: HEIMBERG WOLFGANG
IPC: F02M51/04
Filed: 1996-04-24
Abstract: A fuel injection device works based on the principle of storage of energy in a solid body and is designed as a reciprocating piston pump with a feeding piston (35, 24) that stores kinetic energy during an almost resistance-free acceleration phase.      The stored kinetic energy is abruptly transmitted to the fuel contained in a compression chamber (66), generating a pressure wave for injecting fuel through an injection nozzle. The means that interrupt the resistance-free acceleration phase are designed as a valve with a valve body (50a) and a valve seat (57) shaped on the feeding piston (35, 24).      To generate the pressure wave, the valve closes the compression chamber (66) so that the kinetic energy of the feeding piston (35, 24) is transmitted to the fuel enclosed in the compression chamber (66). The valve seat (57) and the valve body (50a) lie at the front end of the feeding piston (35, 24), seen in the direction of injection, and separate the compression chamber (66) from the feeding piston (35, 24).

Title: High fidelity vibratory source seismic method using a plurality of vibrator sources
Inventor: ALLEN KENNETH PAUL
IPC: G01V1/28
Filed: 1996-09-27
Abstract: A method for recording and pre-processing high fidelity vibratory seismic data includes the steps of measuring the motion of the vibrator which is related to the vibrator applied force times a transfer function of minimum phase, causal, linear system relating the actual vibrator output with the measured vibrator motion (50), separation of signals according to generating source (52), determining a ratio by dividing the vibratory seismic data by the measured motion of the vibrator to remove the unknown applied force leaving the earth reflectivity times a time derivative divided by a minimum phase function (54), minimum phase band pass filtering the resulting ratio (54) and performing minimum phase deconvolution (54) to remove the time derivative divided by the transfer function of minimum phase. The method also includes shot ensemble deconvolution (58), receiver ensemble deconvolution (64), statics correction (60), F-K filtering for noise (62), zero phase spiking deconvolution (66), and model dephasing (68). A signal directly proportional to the actual signal that the vibrator is sending into the ground is used in pre-processing. The vibrator motion is measured to provide a signal that is used to process the data. The data is divided by the relative of the actual transmitted signal in frequency domain.

Title: A cascade nucleic acid amplification reaction
Inventor: KOCH JORN ERLAND
IPC: C12Q1/6804
Filed: 1996-12-05
Abstract: A DNA template consisting of multiple tandem repetitions of an oligonucleotide unit is produced by stepwise copying of an oligonucleotide comprising at least one and a half units of a nucleotide sequence showing dyad symmetry by means of a template--and primer-dependent DNA polymerase in the presence of the necessary nucleoside triphosphates during repeated cycles of denaturation and annealing, or by endless copying of a circular oligonucleotide comprising at least one copy of said oligonucleotide unit by means of a nucleic acid polymerase, which is capable of strand displacement and is substantially without 5'-3' exonuclease activity, in the presence of the necessary nucleoside triphosphates and, if necessary, a primer capable of binding to some portion of the oligonucleotide, or by known reactions. Thereafter, in a cascade nucleic acid amplification reaction, a great number of partial and complete DNA or RNA copies of said DNA template is produced by means of a nucleic acid polymerase, which is capable of strand displacement and is substantially without 5'-3' exonuclease activity, by contacting the template with said nucleic acid polymerase in the presence of the necessary nucleoside triphosphates and, if necessary, a primer capable of binding to the oligonucleotide unit, the polymerase thus synthesizing DNA or RNA originating from, ideally, each repeating oligonucleotide unit in the DNA template. These reactions can be used in methods for detecting a target molecule or group and in processes for the amplification of a particular DNA sequence.

Title: Method of making an optical fiber ribbon with improved planarity and an optical fiber ribbon with improved planarity
Inventor: SHEN STEVEN X
IPC: G02B6/44
Filed: 1998-11-23
Abstract: A method of making an optical fiber ribbon with improved planarity and an optical fiber ribbon having improved planarity are described. The method includes the steps of providing a plurality of optical fibers and arranging the plurality of optical fibers to form a planar optical fiber arrangement. The planar optical fiber arrangement defines a first common tangent plane and a second common tangent plane. Matrix material is applied to the planar optical fiber arrangement to form a first uncured layer of matrix material such that the first layer does not extend beyond the first or the second common tangent plane by more than twenty micrometers. The first uncured layer of matrix material is then cured to achieve a degree of cure between 70% and 95% to provide a cured first layer of matrix material on the planar arrangement. Next, matrix material is applied over the first cured layer to form a second uncured layer of matrix material. Finally, the second uncured layer is cured until a degree of cure in the second layer is at least 85% to form an optical fiber ribbon with improved planarity. The optical fiber ribbon of the present invention can be made according to the method described.

Abstract: L'invention porte sur un procédé de conservation de spécimens à activité biologique par vitrification consistant à les déshydrater de manière à obtenir un véritable état vitreux à la température de stockage par un refroidissement subséquent. Le procédé se base sur la constations que pour stocker les échantillons à l'état vitreux véritable, la température de déshydratation doit dépasser la température de stockage envisagée. Comme la température de vitrification décroît rapidement avec la teneur en eau (par exemple l'eau pure se vitrifie à T¿g? = -145 ·C, alors qu'une solution à 80 % en poids de sucrose se vitrifie à Tg = -40 ·C, et que la sucrose anhydre se vitrifie à T¿g? = 60 ·C), l'échantillon doit être fortement déshydraté pour porter la (T¿g?) au-dessus de la température de stockage (T¿s?). Comme l'a constaté l'inventeur, la température de déshydratation doit être supérieure à la température de stockage envisagée, l'état vitreux étant ensuite atteint par refroidissement après déshydratation.
