Title: Frequency-dividing-transponder tag
Inventor: FERGUSON LUCIAN G
IPC: G06K7/10
Filed: 1993-10-01
Abstract: FREQUENCY-DIVIDING-TRANSPONDER TAG            ABSTRACT OF THE DISCLOSURE   A frequency-dividing transponder tag includes an active strip of magnetic material that, when in the presence of a magnetic bias field within a predeter-mined magnetic field intensity range, responds to excitation by electromagnetic radiation of a first predetermined frequency by radiating electromagnetic radiation of a second predetermined frequency that is a frequency-divided quotient of the first predetermined frequency; and a pair of bias strips of magnetic material dis-posed in relation to the active strip in a common housing with the active strip for magnetically biasing the active strip with a magnetic bias field within the predeter-mined magnetic field intensity range. The bias strips are formed from extruded magnetic material having a high coercivity of at least approximately 1530 oersteds and a high retentivity (remanence) of at least approximately 1970 gauss. The bias strips are cut from an extruded magnetic material ribbon having a width less than the given length of the active strip and a magnetic moment parallel to the lateral dimension of the ribbon, with the bias strips being cut at an oblique angle to the lateral dimension of the ribbon so that each bias strip has an oblique magnetic moment having longitudinal and lateral components; wherein the bias strips are disposed in the housing such that their respective longitudinal components aid each other and their respective lateral components oppose each other. The hous-ing includes a cavity in which the active strip is disposed for vibration, with the cavity having walls that are coated with a permanent anti-static material to prevent the active strip from being attracted to the walls. Another embodiment of the tag includes a first set of said active strip and said pair of bias strips and a second set of said active strip and said pair of bias strips, wherein the first set is disposed in the same housing as the second set, with the active strip and the bias strips of the first set being perpendicular to the active strip and the bias strips of the second set.

Patent CA-2133799-A1 (CA)
Title: Log chipper for lowering peak power requirements and raising chip quality
Inventor: JORGENSEN RAY B
IPC: B27L11/00
Filed: 1994-10-06
Abstract: A log chipper is provided for allowing a lower horsepower rated motor to drive the chipper.      Peak power demand is reduced by cutting shorter chips from large diameter logs, while the length of chips cut from logs of small and medium diameter continues to be of standard specified length, the length of chips cut from large diameter logs only being shortened. The feed rate for large diameter logs is reduced and will therefore result in a reduction of peak power demand achieved by the use of large diameter log positioning means. A first version of the large diameter log positioning means involves the placement of a raised platform on the wear plate where the outer perimeter of the large diameter log would otherwise contact the wear plate. A second version of the positioning means involves raising the heel of the knife clamp at a point where a portion of the outer perimeter of a large diameter log contacts the heel of the clamp. A third version of the positioning means involves grinding an outer face of the knife assembly where a portion of the outer perimeter of a large diameter log contacts the knife assembly. The special grind provides a unique relief angle to cause a shorter chip to be cut from the large diameter log. A final version of the large diameter log positioning means involves the inward adjustment of one of a series of sectional knife assemblies at the point where a portion of the outer perimeter of a large diameter log contacts the knife assembly.
