Abstract: The present invention includes a portable battery with a shaped positive terminal that may be used as a tool for engaging a battery door fastener. The terminal protrudes from the positive end of the battery similar to a traditional cap and base battery terminal. The shape allows the positive terminal to engage with a battery door fastener and, when the battery is rotated, drive the fastener into either an open or closed position. This allows the battery door to be locked or unlocked without the hassle of locating a separate tool such as a screwdriver. To replace a battery, a person uses the replacement battery to disengage the battery door fastener, opens the battery door, replaces the used battery, then closes the door and reengages the fastener with the used battery. The shaped terminal may also serve as a three dimensional identifier for which end of the battery is the positive terminal.

Abstract: Disclosed is a cover for a conventional post, e.g., a T-post commonly used in landscaping, farming, and other fields. The cover has a partially hollow tubular body that is able to slidingly receive a post. A ratchet strip is included on the inside of the cover. Catches on the ratchet strip engage barbs on the post preventing removal. A release strap is provided which is receivable into the hollow cover. The strap comes between the catches and barbs allowing cover removal.

Abstract: A system and method for installing a decorative exterior on a standard signpost is disclosed. A first exterior shell is mounted on one side of the post, and a second exterior shell is mounted on the other. Discs halves are also provided which, when installed between the post and the shells, cause the shells to be securely fastened to the post. In another alternative system, a midsection of the post cover is installed as a tube that slides over two solid discs that are slid onto the post and supported by grommets.

Abstract: A method of imaging a lithographic plate having a printing surface comprising mounting a plate to the plate cylinders of a lithographic press having at least two plate cylinders, a corresponding number of blanket cylinders and an impression cylinder, exposing the printing surface to spark discharges between each plate and an electrode spaced close to the printing surface produced in response to picture signals, the spark discharges producing sufficient heat to change the affinity of each printing surface for printing liquid at the points thereof exposed to the spark discharges thereby producing image spots on each plate corresponding to the picture signals, moving the electrode relative to the plate to effect a scan of the printing surface, and controlling the spark discharges to the plate in accordance with picture signals so that they occur at selected points in the scan so as to form an image of the original document on the printing surface. Imaging apparatus is also disclosed.

Abstract: A printing member for a press without dampening made by forming on a metal substrate an organic plastic layer having an exposed surface which is highly oleophobic and thermally decomposing the layer surface at selected image points thereon without contacting the surface and without penetrating through the layer so that there is a transformation of the surface structure which renders said surface oleophilic at said image points.

Abstract: A printing member for a press with dampening made by forming on a substrate a chromium layer having an exposed surface with pores or capillaries which render that surface hydrophilic and melting the layer surface at selected image points thereon without contacting the surface so that molten chromium is free to flow to and fill the pores or capillaries at the image points thereby rendering the image points hydrophobic.

Abstract: A printing member for a press with dampening is made by forming in a metal body an exposed surface which is cleaned and polished sufficiently to render it oleophilic due to surface tension. Then the surface is heated at selected image points thereon without contacting the surface and without penetrating through the body to create tiny surface fissures or capillaries at the image points which render the surface hydrophilic at the image points.

Abstract: A printing member for a press with dampening made by forming on a metal body, e.g. of aluminum, an exposed oxidized surface with a grained surface structure which renders that surface hydrophilic and heating the body surface at selected image points thereon without contacting the surface so that there is a transformation of the surface structure which renders it hydrophobic at the image points.

Abstract: A lithographic plate for printing without dampening comprising a strong stable substrate, an oleophobic surface layer on the substrate and an oleophilic surface underlying the surface layer, the surface layer being decomposable by spark discharges originating from a non-contacting electrode scanned across the plate surface. A preferred plate embodiment includes a multiplicity of tiny electrically conductive peaks in the plate which point away from the substrate and are in a relatively uniform distribution across the plate surface area.
