A self-fixing table and chair system is provided that embodies a method of strategically placing magnets and in the chair components and table component, respectively, of a chair and table set. Each chair magnet and each table magnet and may be magnetically attracted to each other for suspending the chair components above a supporting surface by removably securing them to the table component.

The purpose of the invention is to prevent serious injuries and cuts that occur from used razorblades that are used with many types of blade holding devices such as razor knifes, scrapers and alike. The blade disposal apparatus was invented to dispose razor blades when no longer needed. The invention has a tamper proof body structure and can be mounted by screws or its magnetized backing. Once the blade disposal apparatus is full of blades the entire device must be discarded. This device can remind people who use them that there is a safe way to discard a still dangerous blade.

A method of venting a rotational mold at a predetermined condition by actuating an actuating venting assembly pierces the shell of the molded article and introduces a passageway to relieve pressure during the molding cycle. The actuating venting assembly enables a tactical methodology for venting such molds.

Cleaning apparatus for lithographic printing plates includes a rotating elastomeric roller that contacts imaged plates, which are typically (although not necessarily) carried on a rotary cylinder, at a velocity different from the velocity (if any) of the plate. The roller may spin in the direction of, or opposite to, that of the cylinder and at substantially different speed. Typically, the apparatus is mounted proximate to the cylinder, circumferentially adjacent to the imaging system, and is retractable so as to be selectively engaged when imaging is complete. The apparatus may include, in addition to or in lieu of the elastomeric roller, a second retractable cleaning member for rubbing the imaged plate with a cleaning fluid. The second cleaning member may be an elongated cartridge having an absorbent towel exposed along one face thereof. A cleaning fluid is dispensed onto the towel by, for example, a spraying device. The cartridge is then extended to urge the towel against the printing plate as it rotates.
