Hydraulic flange connectors connect two flange components together, and hydraulic pressure applied to ports in connector holes of one of the flanges tension the flange studs and crush the gasket between the flange components. Each connector has a piston that disposes in the connector hole and can move therein when hydraulic pressure is applied through the port by a pump. A first stud connected to the piston extends beyond one open end of the hole for connection to a first nut, while a second stud connected to the piston extending beyond another open end of the to the second flange component for connection to a second nut. A retainer having seals threads in this other open end of the hole and seals between the hole and the second stud.

An installation tool fastener is particularly adapted for fastening a top plate to a roof support member and other structural connections and is particularly adapted for use with an installation tool. The installation tool fastener has a head with a maximum head diameter and a recess for coupling with a drive coupler. The shank of the head has an unthreaded portion and a uniform thread which has a major diameter approximately equal to the maximum diameter of the head. The head preferably has a slight taper. The thread preferably has a 7.5 thread per inch pitch and a thread angle from approximately 25° to 45°. In one embodiment for a 6 inch fastener, the thread length is approximately 5 inches and extends along the tapered distal tip.

A housing accommodates a motor and a deceleration mechanism. The deceleration mechanism includes a support axis extending perpendicularly to an output shaft of the motor. The housing includes a case and a cover. The case is in a bottomed tubular shape to have an accommodation chamber and a holder portion. The holder portion surrounds a bottom of the accommodation chamber and is in contact with the motor. The cover is mounted to the case to surround an opening of the case and to form a hollow portion with the holder portion to accommodate at least the motor. The motor and the deceleration mechanism are mountable into the accommodation chamber through the opening in one direction from a side of a mounting surface of the case, on which the housing is to be affixed to a support portion of an affixing member.

A reel seat for attaching a reel foot of a reel to a bow includes a shaft, a rear bushing, a cap, a first threaded fastener, and a second threaded fastener. The shaft has a first end and a second end, an outer surface, a first bore formed into the first end of the shaft, and a second bore formed into the second end of the shaft. The rear bushing includes a limiter portion and a receiver portion, the limiter portion being secured to the shaft and defining an increased diameter relative to the shaft to form a stop surface the receiver portion having a bore and being coaxially received over the shaft such that the receiver portion is abutted against the stop surface and rotatable about the shaft.
摘要:
A mechanical coupling for joining pipe elements has segments joined end to end, each segment having projections with surface portions oriented angularly with respect to other surface portions to serve as a guide for the insertion of pipe elements between the segments when arranged in spaced apart relation around a ring gasket. A method of assembling a pipe joint includes engaging the surfaces with ends of the pipe elements and rotating the segments relative to one another to permit insertion.
