Appl. No.:

12/261657

Inventors:

John P. Breault - New Britain CT, US
Steven J. Hemsen - Southington CT, US

Assignee:

Henkel Corporation - Rocky Hill CT

International Classification:

B65D 35/28

US Classification:

222 95, 222391

Abstract:

A dispensing apparatus provides for the dispensing of product from a collapsible tube. The apparatus includes a body for supporting the tube. The body has a forward end for accommodating a dispensing end of the tube and rearward end for accommodating a closed end of the tube. An elongate actuatable plunger is supported by the body. The plunger includes an elongate rod and a base attached to the rod. Actuating means is provided for effecting movement of the plunger in a first direction along the body for engagement with the collapsible tube wall thereby deforming the tube wall and dispensing the contents of the tube from the dispensing end. The actuating means also provides for retractable movement of the plunger in the second direction opposite the first direction. The base is positioned on the rod for dispensing engagement with the tube upon movement of the plunger in the first direction and movable out of dispensing engagement with the tube upon in a second direction.

International Classification:

B05B 11/00

US Classification:

222214, 2223832, 417474

Abstract:

A fluid dispensing apparatus includes an operable peristaltic pump. The pump supports a rigid container which includes an aggressive fluid which is to be dispensed from the container. A vent tube and a dispensing tube extends from the container through the pump. Operation of the pump causes fluid to be pumped out from the container through the dispensing tube while air is pumped into the container through the vent tube. This equalizes pressure in the container and allows fluid to be dispensed from a rigid container.

International Classification:

B65D 88/54

US Classification:

222389, 222334

Abstract:

The subject invention is a system for dispensing a controlled amount of fluid product from a dispensing container which includes a pneumatically driven dispensing actuator. This actuator includes a dispensing cylinder and a movable dispensing piston. The dispensing piston is movable under pneumatic pressure within the cylinder, the cylinder including a volume of hydraulic fluid under the pneumatic pressure acting against the dispensing piston to selectively prevent movement of the dispensing piston. The invention further includes a means for selectively reducing the volume of the hydraulic fluid in the dispensing cylinder to allow the controlled movement of the dispensing piston. The controlled movement of the dispensing piston causes controlled displacement of the fluid product from the dispensing container. Advantageously, with the subject invention, a force may be generated and applied to a plunger, which can be accurately controlled. As will be recognized by those skilled in the art, the force results in movement of the plunger, which, in turn, translates into an accurate amount of fluid product being dispensed from the dispensing container.

Appl. No.:

8/378207

Inventors:

Steven J. Hemsen - Southington CT

Assignee:

Honeywell Inc. - Minneapolis MN

International Classification:

F16K 3102

US Classification:

25112921

Abstract:

A noise dampening feature is provided to a valve by incorporating an annular resilient member in association with the plunger of a solenoid valve. The annular resilient member comprises an annular portion and a series of protrusions extending axially away from the annular portion. A plunger of a solenoid valve is adapted to have an annular groove into which the annular portion of the resilient member is received. By preventing the direct physical contact of the upper surface of the plunger with the lower surface of a stop member, the resilient member prevents the clicking noise that is undesirable in certain circumstances. In order to avoid restricting the normal flow of fluid through the valve, the resilient member is provided with a plurality of protrusions and recesses, or interstitial spaces, that allows fluid to flow radially inward from the region of the fluted sides of the plunger toward the central location of a secondary port formed through a stop member.

C09J 5/00

Abstract:

An apparatus and method for dispensing a multi-component adhesive using a pair of non-contact jetting valves. The multi-component adhesive is a combination of two or more individual reactive adhesive components, which are not adhesive by nature on their own, but which can be mixed to chemically react and form an adhesive. The individual reactive adhesive components are held and dispensed separately by the apparatus, such that the individual reactive adhesive components do not mix before they are deposited onto the target substrate.

International Classification:

F04B 53/06
F16K 15/04
B05B 9/04
F04B 53/10

Abstract:

A positive displacement pump for dispensing fluid includes a fluid body sub-assembly including a fluid body and a negating check valve. The negating check valve includes a negating body defining a dispensing opening. The fluid body and the negating body form a flow path for the fluid. The fluid is dispensed through the dispensing opening. The positive displacement pump is primed by allowing trapped air within the flow path to flow out of the dispensing opening. The negating check valve may be fully or partially attached to the fluid body. The trapped air within the flow path flows out of the dispensing opening when the negating check valve is partially attached to the fluid body.
