Appl. No.:

10/397116

Inventors:

John Charles Larson - West Chester PA
Alan Arthur Burmester - Rice Lake WI
Anthony Christopher Weyek - Rice Lake WI
Travis Lynn Gibson - Cumberland WI

Assignee:

E. I. du Pont de Nemours and Company - Wilmington DE
Rice Lake Weighing Systems, Inc. - Rice Lake WI

International Classification:

B65B 130

US Classification:

141 83, 141129, 141130, 141134, 222318, 222 55

Abstract:

A dispensing apparatus includes recirculating systems though which the dispersants are recirculated to prevent settling of solid components, such as pigments that may be present in the dispersants. The apparatus includes dispensers located on a movable table positioned inside a frame assembly of the apparatus. The table is positioned to dispense a selected dispersant into a container placed atop a weighing scale through the dispenser selected in accordance with a recipe. The weight of the selected dispersant is monitored by the weighing scale and once a desired amount of the selected dispersant is dispensed, a signal is received by the apparatus from the weighing scale to switch off the dispensing of the dispersant. The table is then moved to deliver the next dispersant, required in the recipe. The process is continued until all the desired dispersants are dispensed in the container to form the composition, such as an automotive paint.

Appl. No.:

10/040571

Inventors:

Ira Spier - Bronxville NY, US

Assignee:

MACROPARK, INC.

International Classification:

G08G001/14

US Classification:

340/932200, 705/013000

Abstract:

A terminal of a parking meter system includes two-way audio and visual communications with a central administration station for assisting customers using the terminal. The terminal has coin and bill acceptors in communication with a computer for managing the terminal operation. A video display in the terminal can alternately display payment information or a camera view of a central station operator when communication is initiated. Two-way communication between the terminal and central station provides immediate trouble-shooting and resolution of customer complaints such as lost bills or coins and failure to credit payment. Monitoring of the terminal by a central station operator provides prompting for service for coin and bill collection and/or impounding illegally parked vehicles, among other attendant functions, so that an attendant is only present as needed.
