Patent CA-2280390-A1 (CA)
Title: Mechanical hay distributor
Inventor: WHATLEY ROBERT TODD
IPC: A01D90/10
Filed: 1999-08-13
Abstract: A hay distributor is provided that distributes large rectangular hay bales or flakes of hay, operating on a conveyor principle wherein the bales are slowly advanced from the bed of the vehicle to its edge as the vehicle is driven, whereupon by mechanical action the bale is cleaved to flake. A base plate is provided, forming a pivoting point of retrofit attachment of the main frame of the invention to the vehicle bed. The base plate provides a mounting means for conversion of invention between side or rear-end distribution of hay from the bed of the vehicle.      Next, an operating main frame comprises a) rails, having a initial end and a terminal end, along which a hay bale is advanced, and b) incline-adjustable ramps disposed in the path of the rails at their terminal ends, over which the bale advances on its approach to the edge of the bed of the vehicle, which ramps cause natural cleavage of the bale into individual flakes by creating a line of stress. The flakes thus fall off the edge of the vehicle bed, without operator assistance. A skid assembly travels on the rails to drive the bales, and, a remotely-operated motor unit drives the skid assembly. The motor unit may employ a) a winch mounted to the vehicle bed remote from the operating frame and 2) a cable and pulley assembly to transfer drive forces to the skid assembly.

Title: Method of plasma incision of matter with a specifically tuned radiofrequency electromagnetic field generator
Inventor: COCCIO DAMIAN
IPC: A61B18/12
Filed: 1998-09-24
Abstract: A method of incising matter with a harmonious plasma cloud. An inexpensive radiofrequency generator and power amplifier generates an electromagnetic wave which is transmitted from an incising transmitter probe. This electromagnetic wave is impedance matched, frequency matched, and power matched to initiate and sustain a harmonious plasma cloud with low atomic particle turbulence and chaos. This harmonious plasma cloud forms a coating over the surface of the incising tip as well as acts to reduce the energy output needed from the power amplifier. The electromagnetic wave is also used to produce a Pinch Effect to compress, contour, shape and control the harmonious plasma cloud. The electromagnetic wave is furthermore used to trap and contain the plasma cloud without the need of a solid matter containment vessel according to the Magnetic Bottle Effect of physics. The Tunnelling effect of physical chemistry is utilized to amplify the energy delivered to the harmonious plasma cloud while shielding matter surrounding the intended path of incision from potential radiation exposure. The system provides an efficient, effective, safe, clean and inexpensive approach to producing an incision in matter.

Abstract: A fold flat vehicle seat comprises a movable track member slidably engaging a fixed track member. A seat assembly is mounted thereon for longitudinal sliding movement of the seat assembly relative to the fixed track member. A track lock is operatively interconnected between the movable and fixed track members and movable between a locked configuration whereat the movable track member is precluded from moving longitudinally relative to the fixed track member and a released configuration whereat the movable track member is permitted to move longitudinally relative to the fixed track member. The seat assembly includes a seat cushion member mounted on the movable track member and a seatback member mounted on the seat cushion member for forward folding about a seatback pivot axis between a substantially upright occupiable position and a substantially horizontal load supporting position. A seatback latch is operatively engaged between the seatback member and the seat cushion member to selectively control the forward folding of the seatback member. A spring biases the seatback member toward the substantially horizontal load supporting position. A link arm is provided for causing rearward longitudinal movement of the seatback member relative to the fixed track member to a predetermined longitudinal position as the seatback member is forwardly folded about the seatback pivot axis from the upright occupiable position to the substantially horizontal load supporting position when the track lock means is in the released configuration.

Title: Method and means for conveying and processing an extruded sausage strand
Inventor: HAMBLIN DAVID
IPC: A22C11/00
Filed: 1999-10-28
Abstract: A conveyor (52) for moving the strand from a sausage making machine (10) has J-hooks extending downwardly from a continuous chain conveyor (52). The conveyor (52) picks up the loops (28) of the strand at a loading station (16) immediately adjacent the discharge end (24) of the machine, and conveys the loops (28) to a processing station (14) for smoking or the like.      The conveyor (52) then moves the loops (28) to an unloading station (18) for removal of the strand from the conveyor, whereupon the conveyor(52) downstream of the unloading station (18) returns to the loading station (16) to pick up additional product. A conveyor take-up mechanism (20) is located immediately downstream from the loading station (16) to permit the conveyor to cease movement at the loading station (while the casing on the machine is being replenished) while the conveyor can continue movement in the processing area. Sensors and controls interconnect the machine and the conveyor (52) tocoordinate the operational functions of each. A method of producing and processing a strand of sausage of foodstuff involves producing a linked strand of material, depositing linked loops thereof on the hooks of a moving conveyor, controlling the coordinated activity of the production of the product with the movement of the conveyor; moving the product to and through a processing station, and thence to an unloading station, while periodically stopping the movement of the conveyor and the operation of the machine while continuing the movement of the conveyor through the processing area.
