Abstract: A dispersive electrode has been devised for electromedical equipment consisting of a thin sheet or layer of electrically conductive material covered on one or both sides by a flexible laminate. To facilitate attachment to the skin of a patient during electrosurgery, the laminated sheet may be secured to a resilient backing member preferably having bifurcated ends to which an adhesive is applied in order to effect a secure connection to various parts of the body and to more readily conform to the contour of different parts of the body. The pad includes a tab projecting from one end of the conductive layer which tab is preferably of rounded or somewhat circular configuration and adapted to be inserted into a snap-type connector.

Abstract: In night vision apparatus, a wide-angle view, and a narrow-angle but higher-resolution view, are observed simultaneously in superposed relationship to provide a composite view which is wide-angle, but has a higher-resolution part. Night vision goggles or binoculars have two optical channels, each with its objective lens system, image intensifier and eyepiece. One of the channels presents a wide-angle view of a scene to one eye and the other channel presents a higher-resolution view of a central portion of the scene to the other eye, both views having the same magnification. A degree of stereoscopy can be obtained in the central portion of the scene even though one eye is only receiving a low resolution view.

Abstract: A counterweight system for use with an earthmoving apparatus adapted for selectively counterbalancing the front end of the drive machine thereof or the rear end of the drive machine thereof depending on whether or not an earthmoving structure is attached to the rear end. The rear end earthmoving structure may comprise a backhoe which is removably connected to the drive machine permitting the apparatus at times to function solely as a bulldozer or front loader apparatus. The counterweight system permits the counterweight to be installed on the front end earthmoving structure when the backhoe is in use thereon to counterbalance the backhoe. The counterweight system permits the counterweight to be installed on the rear end of the drive machine when the backhoe is removed therefrom so as to reversely counterbalance the apparatus when utilizing the same as a conventional front loader or bulldozer apparatus.

Abstract: This is concerned with a fabricated connector, and method of making it, for joining flexible conduit to a terminus, such as a box or enclosure or the like. The connector has a sheet metal fabricated housing that free-wheels on the flanged end of a body member and is provided with a threaded pilot that is adapted to project into the inside of the end of the flexible conduit.

Abstract: A method of applying a stable, aqueous, low viscosity resin composition to porous or absorbent materials and controlling the migration thereon which comprises: treating the porous or absorbent materials with an alkaline material to raise its pH above about 7 and give it an alkaline reserve potential; and applying to the porous or absorbent materials a stable, aqueous, acidic low viscosity resin composition having a viscosity of less than about 1,000 centipoises and an acidic pH less than about 7 and comprising from about 10% to about 60% by weight on a solids basis of a synthetic resin and from about 0.
