Abstract: A turf aerator includes a wheel-supported frame and drive means for propelling the frame across the ground at a predetermined rate. A pair of substantially vertical tine arms each having a plurality of downwardly directed turf coring tines attached to the lower end thereof are mounted on the frame for alternate penetrating engagement with the ground. A tine arm actuating mechanism produces an essentially elliptical movement of the upper end of each tine arm, the major axis of the elliptical movement being substantially vertical. A rocker mechanism indirectly connects the lower end of one tine arm with the lower end of the other tine arm such that the horizontal movement of one tine arm with respect to the frame upon engagement of that tine arm with the turf produces an equal and opposite horizontal movement of the other tine arm and vice versa. The aerator produces a substantially vertical insertion and withdrawal movement of the tines and a resultant minimal disturbance of the surrounding turf area.

Abstract: A support for patient monitoring equipment is provided by a vertical column suspended from a ceiling by a carriage assembly mounted for transverse movement on roller assemblies along a pair of parallel ceiling-mounted tracks. The column is stabilized by the roller assemblies which include rollers bearing on the track flanges as well as rollers disposed beneath the tracks effectively preventing rocking movement of the column. In the preferred embodiment, a rotatable sleeve is disposed on the vertical column for mounting of an infusion pump and permits rotation of the pump to any desired facing position. A telescoping tube within the column is selectively positionable between upper and lower positions and carries IV bottle mounting arms on its upper end. The arms may be lowered for attachment and removal of the bottles and raised and locked at an elevated operating position.

Abstract: A grass/lawn debris handling system for a lawn mower having a side grass discharge duct includes a rigid hopper mounted on the side of the mower proximate tha grass discharge duct. A substantially vertical chute mounted on the discharge duct communicates at its lower end with the duct and at its upper end with the front end of the hopper. Relative movement of the chute and the hopper as well as the selective disconnection and reconnection thereof is made possible by an oversized opening in the hopper for receiving the chute upper end and flexible seal means in the opening for sealing the space between the hopper and chute end. The hopper is supported on a lift arm pivoted at the rear of the mower. A cylinder provides selective pivotal movement of the lift arm to rotate the hopper into an elevated dumping position. A hinged hopper door of air-permeable material opens automatically when the hopper is elevated to its dumping position to permit discharge of the hopper contents.
