Abstract: A mounting assembly for a davit to support a platform by supporting lines, is secured by a receptacle flush mounted on an elevated floor of a building. The mounting assembly is secured and moved into engagement with the mounting assembly by a socket of a mounting assembly receiving the davit engaging the assembly with the mounting assembly by engagement blocks which engage a locking member in the receptacle upon tilting of the davit mounting assembly toward a vertical position.

Abstract: An engine cleaning system has a cleaning solution container having a filter element therein and is adapted to establish a predetermined quantity of solution for a particular engine. Solution is pumped from the solution container to the engine interior by the engine oil pump, and a solution drain line connects the engine interior and the solution container. Oil and cleaning solution are pumped by the engine oil pump continuously during the cleaning process. The solution container has a removable closure for filter replacement and a drain valve for solution and oil.

Abstract: Elongated flood control bags are filled with pillows filled with liquid or inflated with air, the pillows being arrayed in each bag, typically end to end and stacked. The bags are deployed at ground level for control of liquid flow to protect property and terrain against flow of water and rain.

Abstract: A sump containment apparatus for a fuel storage tank has a manhole skirt communicating with a sump interior, a bladder seal with a first portion secured in sealing engagement about an opening in the sump, and a second portion disposed about an inner surface of the manhole skirt and urged into sealing engagement with the inner surface by mechanical compression, preferably by an expansion ring. An observation port in a manhole cove is openable for viewing into the sump.

Abstract: Filling station equipment eliminates or reduces fumes emission by the provision of a drop tube which extends below the surface level of fuel in an underground tank, and by provision of a seal between the drop tube and a riser pipe, thus to prevent passage and emission of fumes between the drop tube and the riser pipe.

Abstract: An engine oil system cleaning apparatus has a cleaning solution delivery line connected by an adapter to a running engine, and an exit line and a return line from the engine connected at an adapter at the engine oil pan. A fail-safe loop flow circuit, including the exit line and solution delivery line, is provided upon sensing of a pressure drop in the delivery line to operate valves to effect flow through the fail-safe circuit.

Abstract: A visor for a head of a person has a closed spring-like loop, a flexible web mounted thereon to define a visor portion, and a head opening. The loop is twistable to form a pair of smaller loops for transport or storage.

Abstract: A portable erectable tower has a body, typically a tank, a base frame, and forward and rearward pairs of legs, the legs of each pair disposed on opposite sides, and a brace with two sections hinged for one-way articulation to extend coaxially to prevent downward movement of the body and to articulate upwardly to enable lowering of the tower body with actuators to act on the pairs of legs and the brace sections for raising and lowering the tower.

Abstract: Conduit coupling apparatus has a first conduit with an annular gasket in an outlet portion to receive a second conduit member sealingly and rotatably to retain the lugs on one member engaging flange portions on the other. Lateral conduits are securable about the outlet of the first member by flange portions secured by threaded fasteners, and quick-connect fittings are utilized.

Abstract: An accommodating intraocular lens to be implanted within the natural capsular bag of a human eye from which the natural lens matrix has been removed through an anterior capsule opening in the bag circumferentially surrounded by an anterior capsular remnant. During a postoperative healing period following surgery, the anterior capsular remnant fuses to the posterior capsule of the bag by fibrosis about haptics on the implanted lens while the ciliary muscle is maintained in its relaxed state by a cycloplegic to prevent dislocation of the lens, and the lens is deflected rearwardly by the fibrosing anterior capsular remnant to a distant vision position against the elastic posterior capsule of the bag in which the posterior capsule is stretched rearwardly.

Abstract: Collars are disposed on loops of intraocular lenses for improved fixation of loops in rims of capsular bags of eyes. A collar may preferably be positioned on an outer portion of a loop and retained on the loop by an enlarged end portion of the loop.

Abstract: A prosthetic apparatus is electrically operable by a user for lifting the user into standing position and lowering the user into a sitting position by power means operated by the user, the apparatus being a motorized wheelchair.

Abstract: The several screen frames of a multistation screen printing machine, such as a carousel screen printer, having multiple work supports movable to the printer stations in succession to effect successive printing of screen images on work pieces fixed to the supports are precisely registered with the work supports by providing each frame with registration features precisely located relative to the screen image on the frame, providing a selected work support with registration features precisely located relative to the printing position of a work piece on the selected support, effecting movement of the selected work support to the print stations in succession, adjusting the corresponding screen frame to directly align its registration features with the registration features on the selected work support, and securing the frame in fixed position.

Abstract: A boltless two-piece rail fastening assembly for securing a railway rail, supported on a conventional tie plate, to a wooden cross tie is comprised of a chair and a rail clip latched thereon. The chair includes a body, having a jaw with a bight configured to receive the clip, and at least one downwardly projecting leg or shank for securing the chair adjacent the base flange of the rail. The rail clip is a torsional spring clip in the general form of an "S" having a rail-bearing leg for proximate engagement with the base flange of the rail and a tie bearing leg for proximate engagement with the tie plate.
