摘要： A multi-story building is constructed by first erecting at least one modular stairwell tower on a concrete base pad. The tower includes a number of horizontally alternating precast concrete modular stairwell units arranged in a stack and corresponding to twice the number of floors in the building. Each stairwell unit includes a precast reinforced concrete tower section having opposite side walls and opposite end walls defining an open top and an open bottom and a height generally equal to one half the vertical distance between two adjacent floors. An inclined stairway and a horizontal landing platform are formed within each tower section and are rigidly connected to the walls. Anchor members are embedded in the base pad and in upper and lower portions of the walls of each tower section, and adjacent anchor members are connected by weld plates. Each stairwell unit has a handrail supported by the corresponding stairway.

摘要： A clutch for a cooling fan for a motor vehicle and method of making the same are provided, the clutch comprising a shaft having a knurled portion that press-fittingly receives an inner race member of a bearing, the shaft having a solid ring shaped portion disposed adjacent the knurled portion and being provided with an outer diameter about equal to that of the outer diameter of the knurled portion and having part of the inner race member of the bearing press-fitted thereon whereby the solid ring shaped portion is adapted to block the flow of viscous fluid out of an enclosed chamber of a housing of the clutch by way of the slots which define protuberances of the knurled portion.
