Filed:

Apr 11, 1980

Appl. No.:

6/139506

Inventors:

Thomas R. O'Connor - Webster NY

Assignee:

Eastman Kodak Company - Rochester NY

International Classification:

B05C 302
B05C 1100
B05D 340

US Classification:

427402

Abstract:

Coating apparatus for carrying out a process of coating in which one or more layers of coating composition are applied to the surface of an object, such as a continuous web or discrete sections of sheet material, by advancing the object through a coating zone in which a flow of coating composition is applied thereto, for example, bead coating or curtain coating apparatus, is provided with a shield to protect the flow of coating composition against disturbance by ambient air currents. The shield is formed of a foraminous material, such as screening or perforated plate material, which functions to diffuse air currents impinging thereon so that their velocity is decreased, with a resulting decrease in their ability to disturb the flow of coating composition. Particular advantage is achieved in using the shield in processes for coating photographic materials, especially in high speed curtain coating operations involving a substantial height of free fall, and in bead coating operations employing a slide hopper where ambient air currents give rise to a problem of differential evaporation of coating composition on the slide surface.

International Classification:

US Classification:

Abstract:

A coarse particle separator for separating and collecting coarse toner particles having a size greater than substantially 500 microns comprises a tank having an inlet and an outlet, the separation being performed within the tank. The inlet to the tank is located at a lower portion of the tank and is connected to an eductor station by an eductor line. Particles are introduced to the inlet by the eductor line at a velocity of approximately 4500 ft/min. The separation of coarse and light toner particles can be performed by reducing the flow velocity so the coarse particles settle out by their own weight. A flow baffle made of a 75 micron screen hinders the passage of coarse particles. The outlet outputs light toner particles to at least one toner storage bin. Alternatively, the tank can have a conical-shaped upper portion which induces a cyclone effect in the flow of toner particles, the cyclone effect resulting in the collection of coarse particles in the lower portion of the tank.

International Classification:

B29C 4700

US Classification:

425 67

Abstract:

An apparatus in which toner fines are recovered from a recirculating liquid transporting toner pellets cut from extruded toner. The recirculating liquid cleans the pellet cutter and forms a mixture of liquid and toner fines. The recovery unit is positioned between the pellet cutter and a station discharging the pellets. In this way, clean liquid flows into the pellet cutter during each cycle. The recovery unit has a housing defining a chamber having two sections. A sloping screen is located in the chamber covering one of the chamber sections. The mixture of toner fines and liquid is dispensed onto the screen. The liquid passes through the screen and is recirculated. Toner fines collect on the screen. A backwash system washes the toner fines from the screen into the other section of the chamber. The mixture of toner fines and liquid is pumped from the other chamber section into a separator.

International Classification:

G06F 3/01
A61B 5/00

Abstract:

A breath-operated interface device having a disposable module and a base. The disposable module having a breath tube with an inlet. A first pressure differential switch is in pneumatic communication with the breath tube and configured to be actuated by a change in pressure in the breath tube. A first signal coupler of the disposable module is in electrical communication with the first pressure differential switch to receive a signal according to an actuation state of the first pressure differential switch. The device may also include a base with a second signal coupler, where the second signal coupler is configured to detachably electrically connect with the first signal coupler of the disposable module. The base also includes a station interconnect configured to interface with an external system, such as, for example, a nurse call system.
