A ratchet nut runner is energized either manually or by a non-manual power source such as a battery, on-line electrical power or a pneumatic supply. A tubular body or housing, which contains speed-reducing and power-amplifying structures, serves also as the handle or hand grip for the device. A driven drive shaft which extends coaxially from the housing is connected to a head of the device through a pivot joint assembly. An important feature of the drive device is that the housing-enclosed drive shaft is pivotable from a non-manual power drive mode in which the drive shaft is coaxial with a tool-engaging stud or coupler, to a configuration in which the drive shaft extends normally of the coupler for rotation of the drive head manually. A switch which connects non-manual power to the drive shaft operates to cut off power when the device is disposed in a manual mode of operation.

A leveling device is disclosed herein for automatically maintaining an absorption refrigerator and freezing unit in a level orientation which includes a ball and socket joint for pivotally mounting the unit to a fixed wall for movement about a horizontal axis. Ducts passing through the ball and socket joint interconnect freezer unit with absorption unit. A solenoid operated leveling device automatically positions the unit to a level position in response to solenoid push rods. A mercury liquid cell carried on the refrigerator unit having quadrant segments operably connects with the solenoids for selectively actuating the push rods when the liquid level changes. The ball and socket joint permits the freezer and absorption unit to automatically level itself by the gravitational pull of the earth assisted by a solenoid operated leveling device that helps position the freezer and absorption unit to a level position. A unit hold down and movable support assembly may be employed when the unit is not cantilevered from its ball and socket joint so that adjustment can be manually achieved.

A photoconductive assembly comprising a conductive substrate, a photoconductive layer and a topcoat comprised of a cured film-forming silicone polymer. The topcoat has a thickness of between 5 and 300 nm and a melting point above 100.degree. C.

Silicone release coatings for efficient toner transfer

A cover and carrier for an assembled fishing rod and reel is disclosed herein having an elongated, rigid tube enclosing the length of rod and a cushioned pouch attached to one end of the tube for housing the reel. A closure is provided for closing an opening or entrance into the pouch while a cap seals the opposite end of the tube. A compression ring or clamp secures the pouch with the tube so that the interiors of the pouch and tube are coextensive.

A silicone coating of a silicone release liner which has a polyester film base is better adhered to the film base and better resists removal when rubbed if the film base is first subjected to electron-beam irradiation while passing through an inert atmosphere such as nitrogen.

Silicone-coated release liner which, even after exposure to light in the presence of moisture, heat or both, displays release properties of less than 20 g/cm width with respect to pressure-sensitive adhesive tape. The coating contains noble metal, and the silicone polymer has substantially no residual ethylenic unsaturation. The silicone polymer is prepared by pre-reacting polydimethyl siloxane with a noble metal catalyst before adding polymethylhydrosiloxane crosslinker.

Vehicle wind deflectors are disclosed herein which are carried on the cab or tractor of a semi-trailer combination and carried on the rear end of the trailer. The cab or tractor deflector includes a base mounting for supporting a panel at an angle so as to deflect ram air immediately ahead of the trailer. The trailer rear end deflectors include a pair of elongated deflectors carried at the opposite corners of the trailer wherein each deflector is arcuate in cross section so as to wrap around the corner in fixed spaced relationship to the structure of the trailer to define an air passageway therebetween. Associated with rear deflector, there is a plurality of air spreaders or pipes which accept a portion of the deflected ram air and conduct the air to given areas at the rear of the trailer to break the creation of any vacuum. Angled flanges are disposed at the entrance to each of said spreaders or pipes to catch and direct ram air into the spreaders or pipes.

A stratum having accurately predictable and controllable release properties toward normally tacky and pressure-sensitive adhesive sheet materials is prepared by reacting two moieties, one terminated with a plurality of isocyanate groups and the other a liquid hydroxyl- or amine-containing organosilicone. The hydroxyl or amine groups are at least three carbon atoms distant from the nearest silicone atom and constitute no more than about 4% by weight of the organosilicone. Depending upon the release characteristics achieved, the reaction product can function as a shaped article, all or part of a release liner, or as a low-adhesion backsize for pressure-sensitive adhesive tape.
