Abstract: The multilayered film has a base layer (A) and at least one surface layer (B).The film-forming component of base layer (A) is at least one copolymer of A1) ethylene and A2) acrylic or methacrylic acid or an ionomer thereof in the absence of substantial amounts of other polymers. The film-forming component of base layer (B) is at least one copolymer of ethylene and up to about 25 weight percent of at least one alpha-olefin having from 3 to 12 carbon atoms, the copolymer having a density of about 0.880 to about 0.935 g/cm.sup.3, in the absence of substantial amounts of other polymers. The weight of the base layer (A) is from 25 to 75 percent by the total weight of (A) and (B). The overall thickness of the multilayered film is from about 5 to about 40 micrometers.The multilayered film is useful for wrapping food.

Abstract: A method is provided for the preparation of ibuprofen by carbonylating 1-(4'-isobutylphenyl)ethanol (IBPE) with carbon monoxide in an acidic aqueous medium, e.g. containing at least 10% of water based on the weight of IBPE initially added, at a temperature of at least about 10.degree. C. and a carbon monoxide pressure of at least about 500 psig, and in the presence of (1) a catalyst complex consisting essentially of a palladium compound in which the palladium has a valence of zero to 2 and is complexed with at least one monodentate phosphine ligand miscible with the organic phase of the reaction medium, the phosphorus/palladium mole ratio in said palladium compound and ligand being at least about 2:1 when the palladium/IBPE mole ratio is such that palladium=1 and IBPE=10,000 or more; (2) dissociated hydrogen ions from an acid which is substantially completely ionizable in dilute aqueous solution such that the mole ratio of hydrogen ions to IBPE added to the reaction zone is at least about 0.

Abstract: The housing for an electrical device or control has a plurality of electric terminals, each having a base into which a screw is threaded with the screw head overlying the base to clamp a wire therebetween. Each base is recessed into the housing in a cavity having one side closed by a tab bent up from the base. The housing cavity and tab prevent lateral access to the space between the screw head and base except where permitted by a hole in the tab. The hole has an inverted teardrop shape and has its longitudinal axis tilted about 20.degree. so the larger end of the hole is further from the screw. The hole is positioned to the left of the screw (when viewed from outside the tab). As the screw is tightened the wire is forced down the tilted axis of the hole closer to the screw while friction between the screw head and the wire urges the wire further into the cavity. The base is provided with raised bumps or a recess. When the screw is tightened the wire is deformed against the bumps or into the recess.

Abstract: The sealed enclosure for an electrical power generation solar concentrator holds and protects the photovoltaic cell from ambient conditions and thermal shock, while multiple fingers of front and rear electrical contact terminals accommodate thermal expansion and contraction of the cell and minimize mechanical stresses on the cell. This sealed enclosure also holds the secondary lens and protects the internally reflective truncated conical rear surface of the lens. A base member has a socket for receiving the cell and its associated front and rear terminal members together with an insulator alignment disc having an opening receiving the cell and for aligning the cell with the axis of the concentrator. A front housing removably screws onto the base member with an inturned front lip gripping a peripheral flange on the secondary lens, thereby aligning it with the cell and firmly pressing it against the cell front for causing thermal mass and inertial of the lens to moderate temperature changes in the cell.

Abstract: This invention is directed to a method of working the free end of heat exchanger tubes, and particularly the formation of braze cups, with the heat exchanger tubes in situ relative to the heat exchanger core with the method including the step of utilizing centering tooling positioned about a tube expansion rod to assure that the braze cup is centered relative to its respective tube axis.

Abstract: A thermostat control for an electric water heater is held in firm contact with the heater storage tank by a mounting assembly comprising a tank bracket including a body having an opening adapted to lockingly fit over the heater tank stud and a pair of laterally-spaced legs extending from the body and having a bent upper end portion adapted to apply spring pressure toward the tank outer wall. The mounting assembly also includes a thermostat bracket carrying the thermostat control and having a pair of laterally-spaced, upstanding ears adapted to fit beneath the upper end portion of the legs on the tank bracket. Each of the ears includes a nib which is received in a slot in the legs on the tank bracket to interlock the two brackets. The tank bracket has a retaining lip located between the laterally-spaced legs which is positioned to tightly bear against the end wall of the thermostat control when the parts are in assembled position and an outward horizontal load is applied.

Abstract: The coupling of driving shaft with a driven shaft is accomplished at high torques and high speeds of rotation using a piezoelectric shack, a passive clutch system, and a hydraulic clutch activation system. The piezoelectric stack is housed in the rotating driving shaft, and extends along the axis of the shaft when it receives an engagement signal. This extension of the piezoelectric stack depresses a disk spring into the hydraulic cavity of the housing of the hydraulic clutch activation system. The pressure thereby generated in the hydraulic fluid compresses a compression ring onto a control disk and translates any rotation of the compression ring into the control disk. A torsion rod in the center axis of the control disk is rotated and, in turn, rotates a plug connected to a sprag clutch. This rotation serves to rotate the sprags into a locking position so that the sprag clutch engages the driving shaft with the driven shaft.
