A threaded connection comprising a pin connecting having dual tapered threads and a box connection having mating dual tapered threads. There is an internal torque shoulder in the box connection, the torque shoulder having a negative angled surface which mates with an angled surface on the nose of the pin connection. The pin connection has an external torque shoulder having a negative angled surface which is engaged and mates with a negative angled surface formed on the face of the box connection.

A boat slip step assembly () for being mounted proximate the corner of a boat slip (). The step assembly () includes at least one tread member () for being mounted in a corner of the boat slip () below the level of the upper surface of the boat dock () that defines the boat slip (). The tread member () has a first edge portion () for being secured to a first dock section (), and a second edge portion () for being secured to a second dock section ().

The preferred orientation, or planar oscillation plane, of a golf club shaft is located by measuring the oscillation of the shaft when an impulse is applied. A reaction mass is mounted on one end of the golf club shaft and is attracted with an electromagnet, and the electromagnet is deactivated in order to initiate vibratory motion. Preferably, the out-of-plane oscillation is measured at a large number of angular positions about the shaft axis, and the principal planar oscillation plane is identified by that pair of opposed angular positions in which the out-of-plane oscillation is smallest. The location of the preferred orientation may be marked on the shaft and used to assemble a golf club with the planar oscillation plane in a predetermined orientation. The straightness of the shaft can also be determined by deriving its spring constant from its oscillation frequency and then measuring the restoring force when the shaft is deflected by the same nominal amount at different angular positions; differences in restoring force can be attributed to differences in actual deflection distance resulting from lack of straightness.

A handling unit for axially transporting elongated objects from a first location to a second location such as from a feed table into a machining unit where machining operations are to be performed upon the object. A feed table, or corresponding depository, supports a plurality of the objects to be transported in parallel relationship, and provision is made to advance the objects so that a single object is placed in a pickup location. An axially movable push rod then engages the end of the object when desired to accomplish the axial transport. This push rod is operated by a rod-less cylinder such that the cylinder and the push rod are in parallel alignment thereby reducing the length of the device to the length of the cylinder. Various embodiments are described, together with that of an 'unloader' to receive the objects after machining and place them on a receiving table or the like.

Device for the axial transport of elongated objects

A safety system for use with boats to be stored in enclosed buildings to minimize potential problems of fires and explosions. This system has a transmitting unit for attachment to the boat itself which is energized when the electrical distribution system of the boat is energized. This transmnitting unit generates a signal indicating this energized state. A receiving unit associated with the building receives any output signal of the transmitting unit and sounds an alarm when this output signal is detected by the receiving unit. In the preferred form, the transmitting unit and the receiving unit utilize infra-red light as the generated and received signal. Also in the preferred embodiment, the detector unit has a plurality of detector elements arranged along the side and top edges of a doorway leading into the storage facility. As a result of this system it can be assured that no boat with an energized electrical distribution system is stored within the facility.

Safety system for boats in dry storage

A rotary drilling machine for forming holes of selected size and spacing in continuous strip material such as elastomeric gasket stock used for the manufacture of gaskets for door openings and the like. This machine has a rotary drum unit which carries the strip material along a portion of its peripheral edges. A plurality of drilling units are mounted on this drum unit so as to move with the strip material. The drilling units are oriented toward the peripheral edge, and these drilling units are moved radially in a proper sequence whereby drill bits thereof move toward the strip material to dril the holes and then retract. Tensioning elements produce friction between the strip material and the periphery of the drum unit to accomplish the movement thereof in unison. The tensioning elements, in a preferred form, have signal generating elements whereby the speed of rotation of the drum unit is controlled to prevent sag in the run of the strip material. The radial movement of the drilling units is preferably controlled with a cam and cam follower arrangement. Air for driving driling motors and water for cooling the drill bits is fed to the machine through passageways in the drive shaft for the drum unit. The construction of this machine provides for very accurate drilling of the holes, and a high rate of production with very little maintenance.
