Filed:

Jun 1, 2004

Appl. No.:

10/858122

Inventors:

William J. Swanson - St. Paul MN, US

Patrick W. Turley - Eden Prairie MN, US
Paul E. Hopkins - Savage MN, US

Assignee:

Stratasys, Inc. - Eden Prairie MN

International Classification:

B29C 41/02

US Classification:

264 39, 264 401, 264308

Abstract:

A filament cassette and a filament loading assembly supply modeling filament to a liquifier in a three-dimensional deposition modeling machine. Two or more cassettes containing spooled filament are inserted into the machine. A strand of filament from a first one of the cassettes is fed to the liquifier for extrusion. Without operator intervention, the filament strand from the first cassette is withdrawn from the liquifier, and a filament strand from a second one of the cassettes is fed to the liquifier. The switching of filament feed sources is triggered by an event, such as an identification that the filament from the first cassette has reached a predetermined minimum length. In this manner, a used primary filament cassette is automatically replaced with a standby filament cassette, so that the machine need not experience downtime waiting for an operator to change the cassettes.

International Classification:

B67D 1/08

US Classification:

222148, 2223213

Abstract:

A product dispensing system is provided. The product dispensing system includes a dispensing device and a sealing assembly. The dispensing device is configured and arranged to pass product out of a dispensing orifice in the product dispensing system. The sealing assembly is configured and arranged to wipe and seal the dispensing orifice to prevent exposure of unused product with ambient air when the product dispensing system is not dispensing product.

International Classification:

B65B 1/30
B65B 3/28

US Classification:

141 83, 141102

Abstract:

A solid chemical product is dispensed to prepare a requested amount of a use solution having a requested concentration of the chemical product. In some examples, a target amount of a diluent and a target amount of the chemical product required to prepare the requested use solution are determined. The target amount of the diluent is dispensed into a container. At least some of the diluent in the container is applied to the solid chemical product to create a resultant use solution, which is directed back into the container. The diluent from the container is applied to the chemical product until the amount of the use solution in the container satisfies the requested amount. In some examples, the target amount of the diluent and the target amount of the chemical product are measured by weight.

International Classification:

B29C041/02

US Classification:

425/073000, 425/375000

Abstract:

An apparatus which extrudes flowable material from a liquifier includes a system for loading filament supplied in a cassette. The cassette is loaded into a loading bay of the apparatus. A strand of filament from the cassette is engaged and advanced along a path to the liquifier using a drive wheel or roller pair. A conduit having an entrance in the loading bay guides the filament as it is advanced. The filament loading system of the present invention provides a convenient manner of loading and unloading filament in a three-dimensional modeling machine, and can be implemented in a manner that protects the filament from environmental moisture.

International Classification:

F26B 3/00

US Classification:

34446, 34491

Abstract:

A dryer monitor detects when textiles in a dryer are dry, detects when textiles in a dryer are overdry, and/or may count dryer cycles. The dryer monitor includes a humidity sensor, a temperature sensor, a controller and various status indicators. The humidity and temperature sensors may be located outside the drying compartment of the dryer. In the case of a clothes dryer, the humidity and temperature sensors may be located outside the drum of the dryer and may be located, for example, in the exhaust compartment of the dryer. The dryer monitor determines dryness of items in the dryer, and may also determine whether the items are overdry, based on humidity information received from the humidity sensor. The dryer monitor counts dryer cycles based on temperature information received from the temperature sensor.

International Classification:

F26B 19/00

US Classification:

34572

Abstract:

A dryer monitoring system receives dryer information from one or more sensors concerning operation of one or more dryers, such as clothes dryers. For example, the dryer monitoring system may receive temperature, humidity, and/or dryer on/off information concerning the dryers. The dryer monitoring system may analyze the dryer information and generate reports communicating the dryer information, identify possible maintenance issues with the dryers, identify ambient environmental conditions that may lead to inefficient drying, identify possible operator errors, and/or diagnose other dryer conditions that may be determined based on the dryer information.
