Xerox Corporation - Norwalk CT

International Classification:

B41J 2/175

US Classification:

347 88, 347 22, 347 25, 347 17

Abstract:

A method of operating a drop generating printhead including heating the printhead, providing melted phase change ink to the printhead, allowing the printhead to cool, and while the printhead is cooling, pressurizing the phase change ink in the printhead with a pressure that is sufficient to substantially maintain meniscuses at the outlets of the nozzles of the printhead as the phase change ink in the printhead solidifies. Also disclosed is a method of operating a drop generating printhead including heating the printhead, and pressurizing solidified phase change ink in the printhead with a pressure that is sufficient to substantially maintain meniscuses at the outlets of the nozzles of the printhead as the phase change ink in the printhead melts.

Appl. No.:

13/966159

Inventors:

David Walter Reeves - Orinda CA, US

International Classification:

F16L 19/025

US Classification:

277314

Abstract:

A method is provided for forming a gasket for sealing opposing flange surfaces of a pipe having corrosive fluid flowing therethrough. The method comprises defining a gasket profile incorporating a serrated profile core having a flange extending radially inward therefrom. A deformable pillow extends radially inward from the serrated profile core, to define a gasket intermediate portion about the flange, and a gasket inner portion radially inward from the flange. The deformable pillow material and thickness are selected such that upon compression to a thickness no less than the core thickness, the gasket inner portion exhibits a stress level sufficient to preclude corrosive liquid flowing through the pipe from passing radially outward beyond the gasket inner portion, and the gasket intermediate portion exhibits a stress level sufficient to preclude gas and liquid flowing through the pipe from passing radially outward beyond the gasket intermediate portion.

Assignee:

Thrustmaster, Inc. - Tigard OR

International Classification:

F16B 3700
F16B 708
B25G 300

US Classification:

411104

Abstract:

A connector having a horizontal channel member and a vertical channel member connected to the horizontal channel member. The vertical member has a lengthwise hole formed therein for receiving a screw. The vertical channel member is connected at a midpoint of the horizontal channel member such that the vertical channel member and the horizontal channel member form a T-shape protrusion. The vertical and the horizontal channel member are attached to a backplate which circumscribes the members. The connector is inserting into a T-shaped channel in a perimeter edge of a second sheet of composite material. A hole formed in a first sheet is positioned over the hole in the connector and a screw is driven into both holes firmly attaching the first sheet to the second sheet.

International Classification:

G09G 302

US Classification:

345161

Abstract:

A joystick controller for a video simulation system having a geared potentiometer actuation mechanism. The joystick controller comprises a base, a handle mounted on an actuation shaft, and first and second gimbals pivotally mounted on the base by pivot members for rotational movement about respective axes. The joystick shaft is coupled to the first and second gimbals so that the gimbals rotate about their corresponding axes responsive to movement of the joystick handle. Each gimbal has a corresponding potentiometer for sensing the rotational movement thereof. The first gimbal has a first gear connected thereto for rotational movement therewith. The corresponding potentiometer is mounted on the base opposite the first gear and a second gear is connected to the stem of the potentiometer such that the second gear is in tooth engagement with the first gear. A similar gearing configuration is used to couple the second gimbal to the corresponding potentiometer. A cable is connected to the to the two potentiometers to allow their settings read by the video simulation system when the cable is connected thereto.
