Patent CA-2145264-C (CA)
Inventor: LANDPHAIR DONALD KEITH
IPC: A01B73/06

Abstract: The invention is directed to a foldable agricultural implement frame having a first pair of controlling/controlled lifting hydraulic cylinders for lifting and lowering the right wing section and the center section together in a level condition, and a second pair of controlling/controlled lifting hydraulic cylinders for lifting and lowering the left wing section and the center section together in a level condition. In the first pair of controlling/controlled hydraulic cylinders one of the hydraulic cylinders lifts the right wing section and the other lifts the center section.  In the second pair of controlling/controlled hydraulic cylinders one of the hydraulic cylinders lifts the left wing section and the other lifts the center section.  A rephasing valve assembly is used to rephase the controlling/controlled hydraulic cylinder pairs when the implement frame is folded and only the center section needs to be lifted and lowered.  In rephasing the controlling and controlled hydraulic cylinders, the rephasing valve assembly couples the controlling hydraulic cylinder of the center section to the controlled hydraulic cylinder of the center section.

Abstract: A light diffracting structure in an authenticating pattern especially for an authentication label is used for authenticating and protecting against forgery various valuable objects. The light diffracting structure has unique parameters generating a uniquely coloured pattern. The unique parameters are randomly defined by anisotropic process steps during the manufacturing of the diffractingstructure and are not under full control of the producer. This prevents copying or creating an exact replica thereof. The authenticating pattern comprises an integrated structure of a substrate layer and a transparent overcoat layer and the viewable interface therebetween includes the light diffracting structure. The uniquely coloured authenticating pattern can be verified by simple observation with the naked eye which is a prerequisite for ubiquitous verification.

Granted: 2003-05-06
Abstract: An improved device for dispensing and storing multiple rolls of rolled material dispensed on a spool, such as toilet paper, has a storage frame configured to hold the multiple rolls on a generally vertical shaft. The shaft extends upward from the bottom of the frame with the uppermost roll of material being freely accessible for use on the shaft. A lifting assembly is slidably secured to the shaft and positioned below the bottom roll of rolled material. During use, the lifting assembly is raised or lowered to position the uppermost roll of material for use. When the uppermost roll is depleted, any empty spool may be readily lifted from the top of the shaft are the lifting assembly raised again and secured in place to raise the next available roll of material for use. In a preferred embodiment, one face of the frame has an upwardly extending slot and a plurality of notches extending generally perpendicular from the slot at predetermined distances along the slot. An elongated lifting arm secured to the lifting assembly extends through the slot to permit the lifting assembly to be held in a desired position along the length ofthe shaft by engaging the lifting arm in the appropriate adjacent notch. The lifting arm assembly also serves as a visual and physical indicator of how many rolls of toilet paper remain on the shaft.

Granted: 2000-10-10
Abstract: An acoustic wave touch position sensor in which a transducer (14) coupled to a substrate (10) imparts a surface acoustic wave, into the substrate (10) for propagation along a first axis. A reflecive array (28, 34, 30, 36) having selective reflection characteristics for various wave propagation modes is disposed along the first axis to create a higher order horizontally polarized shear wave having an order greater than zero perpendicular to the axis, so that a touch surface (40) of the substrate (10) is imparted with shear wave energy. This energy may be partially absorbed, attenuated or perturbed by an object touching the substrate (10), to create a modified waveform having a characteristic indicative of the axial displacement and/or contact condition of the object with the substrate (10).
