摘要： Rotational control apparatus in the preferred forms of fan clutches (A) are shown including an eddy current drive (224). Specifically, the eddy current drive (224) includes a plurality of permanent magnets (226) mounted circumferentially spaced and with alternating polarity by a holder (228) to a radially extending surface (232) of a housing (62) rotatably mounted by a bearing (58) to the hub portion (24) of a friction disc (28). A magnetically conductive ring (242) is mounted on the opposite axial side of the friction disc (28) than the surface (34) engaged by a friction ring (86, 252) which is rotatably fixed but axially displaceable relative to the housing (62). In the embodiments shown, the friction ring (86, 252) is biased in a disengaged condition from the friction disc (28) by springs (138, 256) and is moved to an engaged condition by a fluid actuated piston (80). In one of the preferred forms, the friction ring (252) includes peripheral gear teeth (256) in slideable gearing relation with gear teeth (250) formed in the housing (62) and is formed of fiber brake material to act as a dampener between the friction disc (28) and the housing (62) to absorb torsional vibration. Thus, the housing (62) and the fan blades mounted thereto are driven with the friction disc (28) in its engaged condition and are driven at a rotational speed less than the speed of the friction disc (28) in its disengaged condition by the eddy current drive (224) and without separate controls for the eddy current drive (224).

摘要： Rotational control apparatus in the preferred forms of fan clutches (A, A') are shown including an eddy current drive (224). Specifically, the eddy current drive (224) includes a plurality of permanent magnets (226) mounted circumferentially spaced and with alternating polarity by a holder (228) to the input of the clutch (A, A') and a magnetically conductive ring (242) mounted to the output of the clutch (A, A'). Thus, the output portion and the fan blades mounted thereto are driven at engine speeds when the clutch (A, A') is air actuated and are driven at a rotational speed less than engine speed by the eddy current drive (224) when the clutch (A, A') is not air actuated and without separate controls for the eddy current drive (224). In preferred forms, a housing (62) comprises the output portion of the clutch (A) which is rotatably mounted by a bearing (58) to the hub portion (24) of a friction disc (28) which comprises the input portion of the clutch (A). In another preferred form, the output portion of the clutch (A') is in the form of a hub (20') rotatably mounted on a stationary shaft (24') and the input portion is in the form of a sheave (50') rotatable relative to the hub (20') and the shaft (24'). Additionally, the hub (20') can be braked by rotatably relating the hub (20') to the shaft (24'). In one of the preferred forms, the friction ring (252) includes peripheral gear teeth (256) in slideable gearing relation with gear teeth (250) formed in the housing (62) and is formed of fiber brake material to act as a dampener between the friction disc (28) and the housing (62) to absorb torsional vibration.

摘要： A fan clutch (A') includes an eddy current drive (224) having a first, magnetic field producing drive component rotatable with the output and a second, coupling drive component rotatable with the input in the form of a sheave (50'). The first drive component includes permanent magnets (226). The second drive component is of a one-piece construction including a steel ring (238) embedded in a body portion (241) formed of aluminum. The steel ring (238) includes locating ears (310) for properly locating and retaining the ring (238) in a mold half (324). Positioning tabs (312, 314) extend from the faces (302, 304) of the ring (238) and prevent the ring (238) from floating in the volume between the mold halves (318, 324) which forms the body portion (241) during the introduction of the molten aluminum. The body portion (241) is integrally formed with circumferentially spaced air moving vanes (264) and an annular disc portion (260) for mounting to the sheave (50').

摘要： The invention relates to a method of constructing a free standing structure in a body of water, comprising the steps of attaching an impervious membrane to a floating formwork, filling the membrane with water thereby expanding it, partially filling the expanded membrane with non-hardenable particulate material which settles to form a body within the expanded membrane resting on the bed of the body of water, removing water from the particulate body so that the body of water exerting a confining pressure on the particulate body renders it coherent, and filling a remaining upper portion of the expanded membrane with a material which hardens.

In particular, the present invention provides a low zinc, low phosphate, acrylic-based, integrated floor care maintenance system that includes a low zinc acrylic floor finish having a zinc content of less than 100 ppm and a phosphate content measured as percent phosphorus of less than 0.4% by weight and a floor finish stripper having no added zinc, no added phosphate and containing from about 0.01 to 5% by weight of an ammonium perfluoroalkylsulfonate wetting and emulsifying agent, such as CAS number 67906-42-7, CAS number 17202-41-4 or a mixture of these. Additionally, this invention provides for a low zinc acrylate floor sealer having a zinc content of less than 100 ppm and a phosphate content measured as percent phosphorus of less than 0.4% by weight, a buffing composition having a zinc content of less than 100 ppm and no added phosphate, and a floor cleaner having no added zinc or phosphate.
