Patent number: 6123302Abstract: A uniaxial mounting for dispensing apparatus includes one or more uniaxial connecting portions on a dispenser and at least one support member having at least one complementary uniaxial mounting portion. The uniaxial mounting portions may include projections and generally complementary channels allowing rapid installation, removal and replacement of the dispenser. The support member may include a locking pivot for further adjustment capability. When dispensing heated liquids, a thermal insulator is incorporated to reduce heat conduction between the dispenser and the support member. The uniaxial mounting may have an alignment guide to ensure proper positioning of the dispenser along the axis of engagement between the uniaxial connecting portions.Type: GrantFiled: October 30, 1998Date of Patent: September 26, 2000Assignee: Nordson CorporationInventor: Edward C.

Patent number: 5873528Abstract: A nozzle assembly (11) of an adhesive dispensing valve (10) includes a first valve (32) adjacent a discharge orifice (34). The first valve (32) opens to permit the flow of adhesive therethrough and closes to terminate the flow of adhesive in response to respective first and second states of the valve operating module (14). The adhesive dispensing valve (10) has a separable nozzle plate (102) that includes the first valve seat (100) and the discharge orifice (34) and is coupled to a nozzle body (72) with a mounting cap (104). A secondary valve (146) is located upstream of the first valve (32) and permits adhesive to flow therethrough in response to both of the first and second states of the valve operating module. However, as the mounting cap (104) and nozzle plate (102) are removed, the secondary valve (146) automatically engages its valve seat (94), thereby terminating the flow of adhesive while the nozzle plate (102) is removed from the valve body (16).Type: GrantFiled: August 15, 1996Date of Patent: February 23, 1999Assignee: Nordson CorporationInventors: William A. Lewis, Edward C. Taylor

Patent number: 5667933Abstract: There are described heat-developable photosensitive image-recording elements which have an alkali-generating system incorporated therein. In the alkali-generating system, a slightly water-soluble metal compound is reacted with a salt of 2-hydroxy-pyridine-N-oxide, or its derivatives, in the presence of a fluid such as water, to form an insoluble precipitate and the alkali required for silver image development during processing. The image-recording materials are useful as image-forming materials in thermographic and photothermographic processes.Type: GrantFiled: November 20, 1996Date of Patent: September 16, 1997Assignee: Polaroid CorporationInventors: Gary E. Cargill, Edward C. Taylor, Peter Viski, Christopher E. R. Orvig
