Patent CA-2179566-C (CA)
Inventor: STAUB RENE
IPC: G03H1/08
Filed: 1996-06-20
Granted: 2006-03-21
Abstract: An information carrier has at least one diffraction pattern which is formed from microscopically fine relief structures and which upon being illuminated with coherent light produces in two spatially separate directions a first and a second image of an object. The images can be rendered visible on a screen or analysed by means of photodetectors. The two images have strong-light and/or comparatively weak-light picture elements and include a symmetry insofar as a weak-light picture element of the second image can be associated with a strong-light picture element of the first image and vice-versa. Such information carriers are suitable as security elements for documents of all kinds such as for example banknotes, passes, identity cards, credit cards etc., wherein at least a part of the security information is not visible under incoherent illumination conditions.

Title: Method of linking a strand of uncased coextruded meat emulsion product
Inventor: KOBUSSEN JAAP
IPC: A22C11/00
Filed: 1996-06-21
Granted: 2000-02-29
Abstract: The method for linking a strand of an elongated coextruded meat emulsion product (10) having an outer surface (14) exposed to the atmosphere without the benefit of an enclosed casing comprises subjecting the strand (10) to a constrictive force at spaced intervals along its length to create a plurality of link points (16) of reduced diameter along the length of the strand (10).  The link points (16) are surrounded by an edible linking material (20, 22) capable of holding the link points (16) in a condition of reduced diameter during a cooking cycle at a temperature in excess of 60° C.  After cooking, the link strand (10) is then subjected to a water based rinse at a temperature of less than 60° C. wherein the linked material will dissolve and will be removed from the strand (10).  The preferred linking material (20, 22) is one from a group of hydroxypropylcellulose and methylhydroxyproplycellulose.

Abstract: A foaming system 10 includes a dual aspirator 13.      The dual aspirator 13 has first and second aspirators 80 and 81 to pick up a first and second chemical concentrate. The diluent first chemical mixture is drawn in through the first aspirator 80 and goes through a first diffuser 46 where the first chemical/diluent mixture is further mixed. Similarly, diluent/chemical mixture is drawn by the second aspirator 81 and flows through a second diffuser 47 where it also is mixed. The two diluent/chemical mixtures then combine after exiting the diffusers and the compatible chemicals are then mixed by the flow of the diluent/chemical mixtures. Flushing lines 68 and 71 provide for cleaning of the dual aspirator 13. Further, the diffusers have a ratio of their diameter to length to aid in the prevention of contamination along with the use of two check valves 48 and 49.

Abstract: A novel DNA regulatory element that confers microspore-specific gene expression has been discovered, isolated, and characterized. The microspore-specific regulatory element can be used to control the expression of a foreign gene that disrupts the function of microspores. Thus, the control of pollen production can be achieved by using the microspore-specific regulatory element to produce male-sterile plants. Various methods can be used to restore male fertility in the F1 generation of such male-sterile plants. In addition, the microspore-specific regulatory element can be used to confer resistance to viral and insect pests.

Abstract: A window glass of a vehicle, to which a hot melt adhesive agent is applied, is pushed while the window glass is held by a jig which is mounted on a robot. An allowable range of temperature of the adhesive agent is set between an upper limit and a lower limit. The upper limit is one at which the adhesive agent comes to have such a holding force above a predetermined value as to prevent deviation of the window glass. The lower limit is one at which a compression reaction force when a bead of the adhesive agent applied to the window glass is crushed to a predetermined thickness becomes smaller than a predetermined value. The adhesive agent is applied to the window glass at such a temperature that the temperature thereof at the time of completion of pushing of the window glass falls within the allowable range.

Abstract: In a multifocal ophthalmic lens comprising an aspherical surface having at every point thereon a mean sphere and a cylinder, a far vision region, a near vision region, and an intermediate vision region, the length of progression i.e. the length over which lens power varies by a set amount in different regions of the lens, is short. To avoid distortion at the periphery of the lens which this would otherwise occasion, the isosphere and isocylinder lines are distributed over the surface of the lens so as to ensure variations in sphere are not too sudden along a 20 mm radius circle centered on the geometric center of the lens and variations in cylinder on the surface of the lens inside this circle are also very small. The lens has an enlarged near vision region and progression is less perceptible to the wearer.

Abstract: The NEG output of the Booth encoding circuit and the multiplicand input are gated so as to minimize switching activity in the multiplier without adding any delay to the critical path thereof. Advantageously, power consumption in the multiplier is significantly reduced, e.g., on the order of 90%, when multiplication is in fact not being performed. Additionally, by changing the structure of the last XOR gate of the partial product generation circuit, the need to gate the multiplicand input can be eliminated. Advantageously, this eliminates the extra circuitry which would otherwise be required to gate the multiplicand input, thus reducing cost. Furthermore, additional power savings may be achieved by efficiently resynchronizing the multiplicand input with the Booth encoded input to the partial product circuit.

Abstract: The present invention provides highly oriented multilayer films. They are produced by coextruding or laminating films having at least one layer of a fluoropolymer, at least one layer of a polyolefin homopolymer or copolymer and an intermediate adhesive layer of a polyolefin having at least one functional moiety of an unsaturated carboxylic acid or anhydride thereof. With this structure the polyolefin layer allows the fluoropolymer layer to be stretched up to ten times its original length. Such a high orientation ratio for the fluoropolymer film increases t he mechanical strength, toughness, and water vapor barrier properties of the fi lm while using a thinner gauge fluoropolymer film. Coextrusion processing can b e done at higher temperatures, i.e. in the range of from at about 280 .degree. C to about 400 .degree.C. These temperatures allow films to be produced in the absence of polymer degradation and film melt fracture.
