Title: Method for achieving the same milk component yield in ruminants fed a low crude protein diet
Inventor: LANTER KENT J
IPC: A23K1/18
Filed: 1997-07-17
Abstract: A method is disclosed providing a more efficient and economical method of feeding ruminants a lower crude protein diet while still achieving the same level of milk and milk component yield as ruminants fed a normal crude protein diet. Specifically, the method involves feeding ruminants an animal feed supplement comprising at least one rumen protected protein in combination with a lower crude protein diet. This method provides a unique approach to feed formulation in that it allows for up to a 50 % reduction in crude protein intake while maintaining the intestinal protein supply and milk component yield. This in turn results in a reduction of animal urinary nitrogen losses as well as a reduction in feed costs.

Title: A gain control arrangement and method
Inventor: BRIERLEY PAUL ANDREW
IPC: H04B10/572
Filed: 1999-02-16
Abstract: A gain control arrangement is suitable for controlling the gain of a variable gain amplifier in dependence on the difference between the actual magnitude and the desired magnitude of a read signal provided over an optical data carrier read channel. The amplitude of the read signal is sampled at periodic sampling points to determine an envelope value based on the sample value at a sampling point and an envelope value at a preceding sampling point, and a gain error value is derived from the difference between that envelope value and a desired envelope value.

The annual interior wall has a cylindrical inner surface defining a cylindrical opening aligned with the first opening, a cylindrical outer surface and a substantially uniform wall thickness. The annular interior wall has a reduced annular waist portion formed in the outer surface at the junction with the annular base portion. An annular exterior wall extends outwardly from the base in spaced apart relation to the annular interior wall. The annular exterior wall has a convex outer surface and a concave inner surface and is dimensioned such that the convex outer surface and the concave inner surface converge to form a vertex spaced from the annular interior wall. The grommet is symmetrical about an axis through the first opening, and the cylindrical opening and is integrally molded from an elastomeric material.

Patent CA-2273461-A1 (CA)
Title: Quick release and storage system based on an eccentric rotating element
Inventor: BUTTERFIELD ROBERT
IPC: A01B63/26
Filed: 1999-06-02
Abstract: Disk coulters are used on numerous soil engaging farm implements to cut furrows into which seed or fertilizer can be deposited. Disk coulters may also be used to cover furrows or simply cut trenches in the land. Typically, an implement or tool bar frame may have several disk coulter assemblies attached to the frame. Some are dedicated to inserting seed into the soil and other fertilizer. In an alternate configuration, the implement or tool bar may have a combination of shanks and coulters. In any given application it may not be necessary to use some of the coulter disks assemblies. Because of the wear on coulters as they move through the soil and encounter rock and other debris, it is advantageous to be able to quickly lift some of the coulter disks out of the soil while operating with other disks. The present invention provides an eccentric rotating element attached to a spring which generally in operation exerts force upwardly on the coulter arm and therefore maintains the coulter in a downward position. By rotating this eccentric rotating element the spring may be released and the coulter disk raised, by hand, off the ground and thereafter locked in place with a spacer element. With the present invention the operator can easily lift or lower coulters in the midst of a seeding operation.
Patent CA-2276510-A1 (CA)
Title: Improved thermionic electric converters
Inventor: DAVIS EDWIN D
IPC: H01J19/08
Filed: 1997-11-14
Abstract: An improved thermionic electric converter (200) uses a wire grid cathode (220) to provide a larger surface area for electrons to boil off. Alternately or additionally, the larger electron emission surface area can be achieved by using a curved electron emission surface. A laser (242) provides quantum inteference to electrons just before they reach the anode, thereby lowering their energy levels such that they more readily are captured by the anode (206). The arrangement provides improved conversion efficiency and reduced electron scatter.

Abstract: A polarization independent tunable optical filter comprises an inherently polarization sensitive angle-tuned filter element and polarization-maintaining multi-pass optics for directing a light beam to and fro through the tunable filter element while maintaining its linear state of polarization. An optical spectrum analyzer apparatus comprises such a tunable optical filter in combination with a polarization control unit for decomposing a light beam for analysis into first and second beams having mutually orthogonal states of polarization states that are parallel to each other and with one of the principal axes of an inherently polarization sensitive angle-tuned filter which selects different wavelengths of the first and second light beams. The light beams are passed through the filter repeatedly by multi-pass polarization-maintaining optics. The filtered first and second light beams are detected and summed to distinguish the energy at the selected wavelength.  Multi-pass optics capable of correcting for inaccuracies in right-angle reflectors are diclosed and may be used in equipment other than such tunable optical filters or optical spectrum analyzers.
