Title: Method of and apparatus for laser treatment of body lumens
Inventor: FOX KENNETH R
IPC: A61B17/00
Filed: 1986-09-05
Granted: 1991-02-19
Abstract: ABSTRACT OF THE DISCLOSURE A laser microsurgical method and apparatus are disclosed for safely treating occluded body lumens with laser energy.  The disclosed method involves the use of pulsed laser energy from an argon-ion laser to destroy the tissue of luminal occlusions, such as atheromatous plaque and the like, with substantially no thermal necrosis of the surrounding tissue.  A flexible catheter and associated laser microsurgical system is also disclosed which provides for aiming of the fibers to transmit the laser beam at the distal end of the catheter and rotational positioning of the catheter to permit coverage of virtually the entire cross-sectional area of the lumen.  A lens system at the distal end of each laser fiber minimizes beam divergence and directs the beam toward the central axis of the catheter.  A further embodiment of the catheter of the invention provides an array of laser fibers which are optically scanned with laser energy to cover the cross-sectional area of the lumen.  The system is designed to minimize the possibility of damage to or perforation of the surrounding tissue of the lumen.

Abstract: ABSTRACT OF THE DISCLOSURE         An ice-making machine includes a plurality of heat exchangers disposed inside a housing and each having an inlet and an outlet to permit circulation of coolant therethrough.  Each of the heat exchangers includes a pair of oppositely directed, corrugated heat exchange surfaces to transfer heat from the fluid within the housing to the coolant.  Ice-making regions are disposed between the heat exchangers.  These regions each have an inlet and an outlet to enable fluid to circulate therethrough. Blade assemblies are provided in each of the ice-making regions to co-operate with the heat exchangers to inhibit deposition of ice on the heat exchangers.  These blade assemblies each include at least one blade of complementary shape to the corrugated heat exchange surfaces to contact respective ones of the surfaces. The blade assemblies are rotatable about an axis generally perpendicular to the plane containing the surfaces.  Drive means rotate the blade assemblies at a rate such that the interval between successive passes of the blades is insufficient to permit crystallization of ice on the surfaces.

Title: Support assembly attached to a large round baler for forming a bale discharge ramp
Inventor: VIAUD JEAN
IPC: A01F15/08
Filed: 1988-04-07
Granted: 1993-05-25
Abstract: SUPPORT ASSEMBLY ATTACHED TO A LARGE ROUND BALER      FOR FORMING A BALE DISCHARGE RAMP      Abstract of the Disclosure A baling machine for forming large cylindrical bales of hay has a gate which can be raised to enable a completed bale to pass under it for discharge.  The bale initially rests on a horizontal support which is biased by a compression spring to swing to a discharge position in which it forms a ramp down which the bale rolls onto the ground.  The support is maintained in the horizontal position by an abutment bar on the gate during the time that the gate is closed, but is released on the gate opening.  In this way energy from the bale is not used for swinging the ramp, so the bale tends to roll further so that it is properly clear of the gate so as not to interfere with the closing of the gate.
