Patent CA-2250313-A1 (CA)
Title: Crop material processor
Inventor: HRUSKA KEVIN
IPC: A01K5/00
Filed: 1998-10-13
Abstract: A crop material processor for disintegrating baled crop material for controlling the crop material for disintegration while preventing crop material from wrapping around the rollers and causing the crop material processor to jam. The crop material processor comprises a container, a disintegrator, a discharge opening and means for manipulating the crop material for disintegration by the disintegrator. The container, receives and contains the crop material. The disintegrator comprises a flail roller and at least one flail. The flail roller is rotatable around its own longitudinal axis. Each of the flails radially extend from the flail roller. The discharge opening is at the bottom of one of the side walls. The manipulation means comprises curved and angled paddles that rotate the crop material without substantially breaking the crop material apart. The corner of the curved paddle grasps the crop material and rotates it. If the paddle were to remain grasping the crop material, the paddle would tend to pull the crop material apart. The curved surface, however, tends to pull the paddle out of the crop material as the roller is rotated. Further, the angled paddles tend to guide the crop material longitudinally toward the centre of the crop processor, that is away from the front and back walls. Moreover, at least one of the sidewalls of the container is adapted for close proximity to the paddles.

Patent CA-2253462-A1 (CA)
Inventor: TUPPER HYDE T
IPC: F16F15/02
Filed: 1998-03-02
Abstract: A vibration damping and isolation apparatus (10) including a passive damping mechanism (28) and an active enhancement mechanism (66). The passive damping mechanism operates to dissipate vibratory and shock forces applied to the vibration damping and isolation apparatus. The passive damping mechanism includes first and second spaced damping elements (30, 32). A first resilient structure (42) connects the first damping element to the second damping element to define a primary fluid chamber (37) between the first and second damping elements. The passive damping mechanism further includes a second resilient structure (50) that defines a secondary fluid chamber (56) which is in fluid communication with the primary fluid chamber via a fluid flow orifice (58). A fluid fills the primary fluid chamber, the secondary fluid chamber and the fluid flow orifice. The active enhancement mechanism includes a system for sensing changes in fluid pressure, loads or other parameters of the passive damping mechanism as a result of the forces applied to the vibration damping and isolation apparatus. An actuator system (67) of the active enhancement mechanism (66) is coupled to the sensing system and acts on the passive damping mechanism, to change the fluid pressure within the passive damping mechanism in response to the sensing system commands. By actively changing the fluid pressure within the passive damping mechanism in response to forces, the active enhancement mechanism enhances the vibratory and shock dissipation of the passive damping mechanism and can actively change the stroke of the apparatus or force exerted by the apparatus.
Patent CA-2258865-A1 (CA)
Title: Apparatus and methods for the disinfection of fluids
Inventor: LEBLANC EDWARD L
IPC: A61L2/10
Filed: 1997-06-20
Abstract: This invention relates to apparatus and methods for the disinfection of fluids and, in particular, to the disinfection of industrial fluids with ultraviolet radiation. These fluids are typically used in manufacturing as coolants in both long and short assembly lines. They commonly accumulate contaminants from multiple and diverse sources including oil and microorganisms. Fluids can be disinfected by establishing a fluid flow rate sufficient to prevent occlusion of the walls of the ultraviolet transmissible portion by contaminants. Fluids may be so heavily contaminated so as to require removal of at least a minimum percentage of contaminants (MPC) prior to irradiation. Such fluids may be processed to remove the minimum percentage of contaminants according to the equation: MPC = 102 - (23.45 x ln V). Subject to removal of the MPC, a flow rate can be established to prevent occlusion of ultraviolet-transmissible portions of the flow path and thereby successfully treat the fluid with a disinfecting amount of ultraviolet radiation. Using these methods, microorganism levels can be greatly reduced with a reduced need for biocides or other anti-bacterial or anti-fungal agents. The methods and apparatus of the invention also comprise a flattened-tube mechanism for increased exposure to UV radiation and a turbulence-generating system to increase effectiveness of radiation treatments. Turbulence-generating systems include means for creating pressure differentials or aeration in the fluid stream as well as various types of structures such as ribbons, paddles, cones, beads or vanes that can be placed within the lumen of the tubing system. These methods are highly effective at extending the useful life of fluids such as coolants and reducing or eliminating the risks posed to workers by heavily contaminated or biocide-treated coolants.
