Abstract: A curtain wall system having a mullion mounting tongue screw-race configuration for improving the efficiency and reliability of curtain wall elements assembled thereto. The curtain wall system includes a face, a first leg, and a second leg. The first and second leg are integrally formed with and extend outwardly from the face and are interconnected via an intermediate web section. Each of the first leg and the second leg include an outer screw-race lip and an inner screw-race lip. The inner screw-race lips and the outer screw-race lips are disposed on opposite sides of the intermediate web section to form a screw race. The inner screw-race lips and the outer screw-race lips are spaced apart by a distance affording engagement by a threaded fastener against each of the inner screw-race lips and the outer screw-race lips. A thickness of the intermediate web section is less than a thickness of the first leg and of the second leg.

Abstract: The dual axis grinder includes a support frame with a plate and a mast. The mast is connected to the boom of an excavator and to a hydraulic stick control cylinder. An auger tube is journaled in a bore through the support frame plate for rotation about a vertical axis. Auger flighting may be attached to the auger tube. A central support housing is attached to the bottom of the auger tube. Two cylindrical drums with grinder teeth are journaled on the central support housing for rotation about a horizontal axis that intersects the vertical axis. The auger tube is rotated by a reversible hydraulic motor. The cylindrical drums are driven by one or two reversible hydraulic motors. Hydraulic fluid is provided to drive the two drums cylindrical through a rotary hydraulic manifold. Chemicals to treat environmental contaminates are supplied through a nozzle adjacent to the cylindrical drums.

Abstract: The grinder mixer assembly includes a drum assembly with end plates rotatably supported on stub shafts. These stub shafts are secured to arms of a yoke assembly. The spindle of a first hydraulic motor is secured to one of the stub shafts. The housing of the first motor is connected to a center portion of the drum by a key. The spindle of a second hydraulic motor is secured to the other stub shaft. The housing of the second motor is to a center portion of the drum by a key. The keys transmit torque from drive rings attached to each motor to driven rings attached to the drum mid way between the end plates of the drum.

Abstract: A temporary glazing panel retainer is disclosed for use in a glazed panel wall construction. The glazing panel retainer engages a glazing clip mounted onto the face of a frame member to maintain glazing panels within their respective glazing recesses on either side of the frame member during assembly of the wall construction. The retainer is configured to be concealed beneath a cover member such that the retainer does not have to be removed to install the cover member.

Abstract: The tree stump grinder assembly (12) includes a drum (176) with end flanges (178 and 180) and a central flange (182). A left hand stub shaft (102) is journaled in the drum (176) by spaced apart roller bearings (122 and 124), a bearing hub (126), and a circular plate (160) attached to an end flange (178). A right hand stub shaft (212) is journaled in the drum (176) by spaced apart bearings (218 and 222), a bearing hub (224) and a circular plate (258) attached to an end flange (180). The central spindle (114) of a hydraulic motor (116) is nonrotatably secured to the left hand stub shaft (102). The housing 144 of the hydraulic motor (116) is journaled on the central spindle (114) and is rotated relative to the spindle when hydraulic fluid is supplied through supply passage 306 and is returned to the sump ( 328) through a return passage (310). Rotation of the housing (144) drives the drum (176) through keys (202, ring member (194) and the central flange (182).

Abstract: The tree stump grinder is adapted to be attached to a backhoe or an excavator with a boom and a stick. The tree stump grinder includes a yoke which is pivotally secured to the stick. A hydraulic grinder swing cylinder is provided to pivot the yoke relative to the stick. Fixed stub shafts are secured to arms of the yoke. Circular end plates are attached to the respective hubs. One hub is rotatably journaled on one stub shaft and the other hub is rotatably journaled on the other stub shaft. A hydraulic motor is fixed to one stub shaft and drives the other hub. A grinder drum is attached to the circular end plates and encloses the hydraulic motor. Oil is supplied to the hydraulic motor through passages in one of the stub shafts.
