Abstract: A method and apparatus for pre-fracturing soil before the soil is cut by coulter wheels to achieve an improved cultivation apparatus wherein a penetrator bar is rotatably mounted on the front of a tillage implement and supports a plurality of adjustable S-tines for penetration of the soil prior to cultivation and resulting interaction of the fractured soil with the coulter blades.

Abstract: A laryngoscope blade is detachably connectable to a hook-on-type laryngoscope handle in conformity with International Standard ISO-7376-1 or ISO 7376-3. The blade comprises a rigid housing having a lower, tongue-engaging flange section extending along the length thereof, a proximal base end provided with hooks or fittings for engaging complementary handle hooks or fittings in compliance with ISO-7376-1 and ISO-7376-3, the proximal base being provided with a hook or flange of such length that the hook or flange comes into contact with the top of the handle such that the blade is prevented from rotating downwardly to such a degree that the distal end of the blade comes into contact with the side of the handle and enabling the blade to be elevated into an operating position to maintain conductivity for powering a light source for the blade.

Abstract: An apparatus for mounting a bird perch to a bird cage wherein first and second sides of a mounting means clamps to the cage and holds a perch holding means onto which a perch is attached and which enables the user to compression clamp a ball joint component at a predetermined angle to position the bird perch.

Abstract: A laryngoscopes blade of the disposable variety for use with a Fiber Optic Green System Handle having a blade portion made from stainless steel and a heel portion made from thermoplastic resin.

Abstract: An apparatus for removing used transmission fluid from an automatic transmission of a motor vehicle wherein a cylindrical reservoir having a rotating wand therein for dividing the reservoir into two chambers, said first chamber being connected to the transmission fluid outlet of the transmission and said second chamber being connected to the fluid input of a transmission fluid cooler wherein the second chamber is initially filled with fresh fluid forcing the wand toward the first chamber and wherein the fluid exiting the transmission due to the pump in the transmission fills the first chamber and forces the wand to rotate to expel fresh fluid form the second chamber into the cooler and the transmission.

Abstract: A leg stretching apparatus comprises an L-shaped, leg and foot support assembly for receiving the leg in straight and bent positions, and the foot in varying positions, including positions of inversion and eversion, to stretch the muscles of the lower leg. The extended portion of the foot support member is pivotally connected to the leg support member, and is adjustably connected by second-class levers to the leg support member to enable a debilitated person to easily exert sufficient force to stretch the various muscles of the lower leg by causing the foot support member to rotate the foot of a patient about the axis of the patient's ankle and to quickly release the exerted force which is exerted by the second-class lever.
