US Patent:

43184316, Mar 9, 1982

Filed:

Dec 8, 1980

Appl. No.:

6/214388

Inventors:

Susan D. Evans - Stamford CT

Assignee:

RJR Foods, Inc. - San Francisco CA

International Classification:

B65B 304

US Classification:

141 90

Abstract:

An electronic control system is described to control the operation of a positive displacement piston filler used for dispensing sauce or a suitable liquid into a flexible pouch which is controlled in movement by means of a Bartelt packaging machine. The electronic control system exerts control over the opening and closing of a dispensing plunger, a rotor valve and a product delivery piston associated with the sauce filler apparatus. A blow-off timing sequence is further controlled to assure that a blast of pressurized air enters the dispensing head of the sauce filler at the most optimum time to assure reliable cleaning of the top portion of the pouch prior to sealing. The control system employs separate timers which serve to enable control of each of the above described operations in one hundredths of a second to enable precise regulation of each phase of the fill cycle.

Abstract:

A method for immunoassay for a ligand suspected to be present in a fluid includes use of an enzyme, a metal ion catalyst for an indicator reaction and a blocked modulator for the catalyst. Ligand present in the fluid binds to an antiligand. The resulting bound fraction activates the enzyme to unblock the modulator. The free modulator activates or inhibits the catalyst thereby modulating the rate of an indicator reaction between a substrate and a redox reagent. The presence of absence of the ligand in the fluid is indicated by a signal, such as a color change or a rate of color change, consequent to the indicator reaction. The invention includes a kit of materials useful for performing the method of the invention.
