Abstract: An expansion sleeve for attaching objects to a relatively thin panel comprises a hollow headed bolt threaded externally for its full length and threaded internally at an end portion remote from the head. The unthreaded internal portion of the bolt has an inwardly projecting apertured annular shoulder into which a drift pin may be driven to expand the sleeve on the interior side of a panel to which the sleeve is to be attached. A jamb nut pulls the expanded sleeve portion firmly against the inside of the panel member and thereafter a threaded rod is threaded into the interior threads of the sleeve so that a nut on the threaded rod may be tightened against the sleeve head. This draws the inner end of the sleeve toward the panel member to increase the pressure of the expanded sleeve portion against the panel. An object to be attached to the panel is then connected to the protruding end of the threaded rod.

Abstract: This invention provides an installation tool for a fastener that includes a nut and a tubular portion having an external knurl, the tool including an internally and externally threaded sleeve, a screw extending through the sleeve and engageable with the nut of the fastener, and an internally threaded element engaging the external threads of the sleeve and having an abutment surface at one end. Advancement of the internally threaded element causes the screw to move the fastener axially, forcing its tubular portion into an opening in a workpiece. The sleeve has a die surface at one end and is then advanced to engage the end of the tubular portion of the fastener for bending it outwardly to form a flange.

Abstract: A water well developer is connected between the end of a hollow drill string and an air-actuated well casing perforator to allow air under pressure to be transmitted through the developer to the perforator. After completion of the perforation, and without removing the perforating tool, a ball is dropped down the hollow drill string to block a passage through a piston that is slidably mounted in the developer, causing the piston to be driven downwardly and to unblock ports through which jets of air are driven into the interior of the casing. As the developer piston is driven down it also completes a relief passage connection that dumps air or water from the perforator.

Abstract: An apparatus and method whereby after a reverse-osmosis water purifier system has been shut down, the first quantity of water, which emanates from the reverse-osmosis filter, does not flow through the pure water storage tank but instead to the drain. Therefore, the water in the reverse-osmosis filter, and which has become contaminated as the result of standing in the filter so that a substantial amount of osmosis can occur, does not contaminate the pure water in the storage tank or system but instead is discarded.

Abstract: A bag handle is formed of two complementary parts, each including a bail fixed to a pair of spaced legs. One bail has a hook and is shorter than the distance between the legs of the other handle part to allow the first bail to be passed through the other handle part. The two parts are arranged with interengaging, supporting shoulders and ledges to enable the second handle part to be supported from the hook on the first handle part, throughout the length of the handle.

Abstract: A drive means is described which includes an electric motor which is pivoted in a substantially balanced position by a biasing means above a wheel of a vehicle. When the motor is actuated, the reactive torque generated causes the output drive shaft from the motor to engage the wheel of the vehicle. When the motor is deactivated, the biasing means forces the drive shaft out of engagement with the wheel.

Abstract: To augment the spin and lift imparted to a bowling ball as it leaves the hand of the bowler, there are mounted in the finger holes inserts having inwardly protuberant ridges at the rims thereof. The tips of the fingers are hooked around these ridges when the ball is gripped, and continue to be at least partially hooked therearound during release of the ball, so that there is sufficient force imparted to the ball during release to create improved spin and lift. There is provided on the inner ends of the inserts walls having central holes therethrough, for purposes of aiding insertion of the inserts, relieving air pressure, and permitting inspection at any time.
