US Patent:

48877700, Dec 19, 1989

Filed:

Jan 19, 1989

Appl. No.:

7/300114

Inventors:

Robert L. Wacker - Wellington OH
Donald E. Shuster - Elyria OH
John Sharpless - Oberlin OH
Alan J. Knobbe - Lorain OH
James C. Murphy - Broadview Heights OH

Assignee:

Nordson Corporation - Westlake OH

International Classification:

B05B 504

US Classification:

239703

Abstract:

Electrostatic liquid spray coating apparatus including a rotary atomizing cup of insulative material driven by an air turbine, is provided with a semi-conductive charging device extending through the cup, the inner portion of which is proximate the inner surface of the cup for contact charging liquid coating material supplied to the rear of the cup as it flows forwardly and outwardly over the rotating cup interior and contacts the charging device prior to atomization at the forward edge of the cup. A generally cylindrical insulative support body, housing a turbine and its associated air bearing and cup drive shaft, has a reduced diameter intermediate section which provides an annular cavity in which are located liquid coating and solvent valves for controlling the flow of liquid coating and solvent to the cup. The charging means in the cup is energized via a stationary conductor which terminates in closely spaced proximity to the outer portion of the charging device on the cup exterior which is electrically connected to the inner portion of the charging device on the cup interior via a series of semi-conductive posts which form the portion of the charging device extending through the wall of the cup between its inner and outer surfaces.

Filed:

Jan 14, 1980

Appl. No.:

6/111995

Inventors:

Robert L. Wacker - Wellington OH

Assignee:

Quest Corporation - Macedonia OH

International Classification:

B66C 140
G01G 2122

US Classification:

177147

Abstract:

A weigh block assembly is disclosed which utilizes compression load-measuring means interposed between a lower plate attached to and supported by a supporting housing and an upper plate attached to the load to be carried and weighed. The upper plate is freely supported on top of the load-measuring means without lateral restraint so that horizontal forces are not absorbed and the pure vertical force is sensed by the load-measuring means and the weighing inaccuracies and other undesirable and unpredictable effects caused by horizontal restraints on the upper plate are eliminated.

Appl. No.:

7/503310

Inventors:

Robert L. Wacker - Wellington OH
Donald E. Shuster - Elyria OH
Ronald J. Hartle - Amherst OH

Assignee:

Nordson Corporation - Westlake OH

International Classification:

B05B 310

US Classification:

239223

Abstract:

A rotary atomizer for spray coating objects includes an onboard color changer valve manifold as well as an optional onboard fluid pressure regulator. The manifold facilitates rapid and efficient color changing while reducing coating material wastage and solvent usage. The invention also contemplates mounting the color changer repositionally along an axis which preferably coincides with the rotary axis of the atomizer. This facilitates installation and removal of the regulator and permits the coating material flow path between the discharge port of the color changer and the atomizing head to be kept short and straight which improves flow control and facilitates thorough flushing of the flow path with solvent. Other improvements including a particular color changer manifold and atomizer head structure are also disclosed.

Gerald Peters - Elyria OH
Dan Reep - Amherst OH

Assignee:

Nordson Corporation - Westlake OH

International Classification:

B67D 537

US Classification:

222108

Abstract:

A mixing and dispensing head is designed for use in a two component foam system. The head includes a body having a mixing chamber formed therein along a longitudinal axis and having a dispensing channel downstream of the mixing chamber. At least two supply portions are connected to the body, with each of the supply portions for supplying one of the components to the mixing chamber at a component entry location. Each of the component entry locations is longitudinally offset from each other. A rotating mixing member within the mixing chamber for mixing the components together to form the foam product. The mixing member includes a cylindrical core having indentations in the core and having angled vanes extending from the core. A shutoff portion is provided for stopping the flow of product from the dispensing channel.

US Classification:

417 63

Abstract:

A diaphragm assembly includes a pair of superposed flexible diaphragms adhesively secured to an annular spacer ring. The space between the diaphragms and the interior of the rings is filled preferably with de-ionized water. The resistivity of the water is monitored to detect conductivity changes upon leakage or diaphragm rupture when pumped materials or pump lubricant mix with the water. Diaphragm assembly and rupture detection methods are disclosed.
