Abstract: A thin film polarizing device has a functional core consisting of at least two alternating thin film layers of metal and dielectric sandwiched between a pair of optical media providing input and output ports. The thicknesses of said layers and the optical constants of said layers and said optical media are selected such that the equivalent admittance of said functional core substantially matches the admittance of said optical media for one plane of polarization, thus allow light with said polarization to be transmitted, and has substantially only an imaginary part for the other plane of polarization, thus allows light with the other polarization to be reflected, at predetermined wavelengths and angles of incidence.
Patent CA-2294429-A1 (CA)
Inventor: OU CHIA-CHIH
IPC: C04B28/02
Filed: 1998-06-19
Abstract: In the preparation of aqueous cement compositions containing a plasticizer, such as an EO/PO polymer-containing plasticizer, or EO/PO comb polymer-containing plasticizer, and further containing clay, such as a smectite clay, which expands when in contact with water, the step of providing an agent operative to modify the clay whereby the plasticizer absorbing capability of the clay is reduced. In exemplary methods of the invention, the plasticizer is an EO/PO (e.g., oxyalkylene) plasticizer and preferably an EO/PO comb polymer, and the clay-activity-modifiying agent may comprise an inorganic cation, an organic cation, a polar organic molecule capable of being absorbed by the clay, a clay dispersant (such as a polyphosphate), or a mixture thereof. For clay-activity-modifying agents which comprise a cation or a polar organic molecule, the agent is preferably added to the clay before water is introduced to the clay. For clay dispersant agents and some organic cations such as quaternary amines (which have a strong affinity for cationic exchange with the clay), the agent may be added before, during, or after water is introduced to the clay.

Filed: 1998-08-26
Abstract: An improved operator's station (70) includes an improved three position seat assembly (90) which allows the operator (200) to stand, perch or sit while maintaining the operator's eyes at essentially the same vertical level (204, 206). The seat assembly includes a back rest (95), a seat (100) that may be raised and lowered, and a movable shelf (105) or perch positioned between the back rest and the seat. In a stand mode of operation, the seat is lowered and the shelf is raised; in a perch mode of operation, the shelf is lowered to provide a partial support for the weight of the operator, and, in a sit mode of operation, the seat is raised for substantially full support of the weight of the operator and the shelf is raised to be flush with the back rest. Two sets of foot pedals (120, 125; 130, 135) are provided in the improved operator's station (70). A first set of pedals (120, 125) is on the floor and includes a brake pedal (120) and a power pedal (125). These pedals are operated when the operator is either standing or perching.      A second set of pedals (130, 135) is raised above the first set of pedals (120, 125) and positioned to be operated when the operator is in the seated position, although the operator may optionally also use one or the other of the raised pedals in either the stand or perch modes of operation, thus providing additional flexibility in operating positions.

Patent CA-2300340-A1 (CA)
Title: Granular material spreader
Inventor: WHITELL DAVID
IPC: A01C15/18
Filed: 2000-03-09
Abstract: A granular material spreader is adapted for towing behind a yard tractor. A  frame supports an inverted cone which is sized to contain a supply of granular material for distribution. The bin sweep rod is carried adjacent to the inside surface of the cone, and turns a drive spring. The drive spring drives a helix, which rotates about the bin sweep rod, driving the granular material toward the narrow base of the cone. Should the helix become jammed, the drive spring snaps past the helix, rather than risk damage by forcing its movement. A bin sweep drive wheel is also driven by the revolution of the bin sweep. Movement of the wheel against the an upper portion of the outside surface of the cone moves the bin sweep rod and helix in a circular path about the inside surface of the cone. A  valve at the base of the cone allows granular material to drop into a housing which defines slots about portions of its perimeter. The blade support plate, rotating at the base of the housing, carries a plurality of blades, which drive the granular material through the slots and from the housing. The vane support plate, rotates just below the blade support plate carrying a plurality of vanes. Movement of the vanes throws the granular material ejected from the housing by the blades in a wide-spread and evenly distributed manner.
