Abstract: A portable frame is supported for vertical movement on a pair of posts adjacent the surface of a table for receiving an object to be marked. A traveling plate is supported for movement on the frame in the horizontal plane above the surface of the object on the table. A ball screw drive connects the traveling plate to the frame for imparting longitudinal movement of the traveling plate in the horizontal plane. A marking head assembly is pivotally mounted on the plate and carries a plurality of impact pins which are reciprocated into and out of contact with the object by operation of programmable solenoid valves. An indexing wheel adjusts the angular position of the marking head assembly to control the size of characters formed by the pins impacting the object. The pins are activated as the traveling table is moved in the horizontal plane to inscribe a desired mark of a preselected character size on the plate.

Abstract: A watch assembly consisting of a case, a removable bezel element and a replaceable band element is provided. The case of the assembly is provided with a pair of brackets depending from its rear face for receiving the band element in the composite assembly. The bezel element is constructed with a pair of retaining platforms for supporting the case when it is placed within the bezel. In assembly, the case and bezel are coupled together, with the platforms holding the case in one direction, and then the band is inserted through the depending brackets of the case, lapping against the bezel and the rear face of the case, thereby preventing movement of the case in an opposite direction.

Abstract: An organic solvent based, thermosetting coating composition of a hydroxy functional epoxy-polyester graft copolymer and blocked polyisocyanate crosslinking agent. The coating composition may be formulated as a hot sprayable, high solids coating composition suitable for use as a chip resistant automotive vehicle primer adapted for use on body panel areas subject to chipping by stones, gravel and other road debris. Alternatively, the composition may be formulated as a high solids composition sprayable with conventional spraying equipment. Hydroxy functional epoxy-polyester graft copolymer is prepared by polymerization of lactone monomers in the presence of hydroxy functional epoxy ester resin precursor. Such precursor resin is formed by reaction of diepoxide chain extended substantially simultaneously with diphenol and dicarboxylic acid and chain terminated with acid component comprising primary hydroxy functional acid.

Abstract: A hermetically sealed low pressure, low temperature cooling system for internal combustion engines which include a thermostat that operates at a predetermined temperature, typically 195.degree. F. Thermostatic control of engine operation temperature is maintained at or in relatively close proximity to this predetermined temperature thereby eliminating overheating and corrosive deterioration of the cooling system. Free coolant flow between the radiator and a small expansion reservoir is maintained at all times with the expansion reservoir positioned at the elevation of an outlet near the top of the radiator or slightly above this elevation. The system is provided with a transparent viewing cap for the radiator so that the level of liquid coolant can be observed at all times.
