Abstract: A compact, economical and easily operated hand tool facilitates reclosing and resealing of paint cans or similar containers that have a frictionally engaged lid and which contain materials that may not be completely used immediately after the initial opening of the can. A pair of handle members are grasped by one hand of the operator and positioned adjacent the rim of the can during use. A drive wheel on one handle member is manually rotated with the other hand and rides around the underside of the rim of the can while a cooperating broader rotatable drum on the other handle member applies seating pressure to successive portions of the lid of the can. Substantially uniform pressure may be applied to all portions of the edge of the lid to effect a complete and reliable sealing of the can.

Abstract: The method of providing an improved soldered electrical connection includes the step of providing a ring over an electrical wire and a terminal which are to be soldered together, and then compressing the ring to form a mechanical connection between the wire and the terminal prior to soldering.

Abstract: A guard ring for long distance transmission cables for preventing wet snow from accumulating on the cables. The guard ring consists of two half collars of a hard elastic plastic material integrally joined by a hinge strap at one end and having interlocking hooks at their free ends to form a closed ring that tightly encloses the cable. Beaks or the like are integral with the inner ends of the half collars and face each other in the area of the hinge. The beaks cover a part of the hinge strap from both sides, so that when the half collars are open, they form, together with the hinge strap, a T-shaped groove for conveniently holding the rings in a row, prior to assembly, on a corresponding T-shaped rail. When the half-collars are closed and the ring secured to the cable, the beaks are bent apart a sufficient distance so that the rings can easily be removed from the rail. An assembly tool is also provided for clamping the rings about the cable.

Abstract: A device is described for facilitating the application of an identifying label to a specific location on the surface of an integrated circuit package. In performing its function, the device permits an operator to lift a self-adhering label containing the desired indicia from its backing card while visually aligning it in the device. The operator then places one end of the integrated circuit package into the device, thereby effectively aligning the label with a desired location on the package surface so that it may be transferred thereto. The device finds particular application in an actual operative high density packaging system wherein the adjacent surfaces of a pair of integrated circuit packages are visible only through a narrow slot in a package hold-down member. Labels, such as those placed on generic PROM packages by operators immediately after programming, are thus precisely located so that their type designation can be seen through the aforementioned slot.
