F23D 14/54

US Classification:

2395811, 431345, 239526, 431254

Abstract:

A torch assembly having features enabling single handed operation. The torch assembly includes a flame control device that can be operated with a user's fingers while the user is holding the torch with the same hand. A controller apparatus of the torch assembly includes a trigger for actuating an on/off valve adapted to permit or stop flow through a fuel line, a regulator adapted to at least partially restrict flow in the fuel line and including a regulator valve, and a controller operatively connected to the regulator to adjust the position of the valve to vary the flow of fuel through the fuel line. The controller is interposed between the trigger and the regulator, and can include a rotatably mounted knob.

US Classification:

2395812, 239526, 431254

Abstract:

A torch assembly adapted to be attached to an associated fuel supply, the torch assembly has a housing, a fuel line at least partially contained within the housing, a burn tube extending from the housing and adapted to receive fuel from the fuel line, an attachment member operatively connected to the housing for connecting the torch assembly to the associated fuel supply, the attachment member in fluid communication with the fuel line for delivering fuel from the associated fuel supply to the fuel line; a control apparatus having a trigger for actuating an on/off valve adapted to permit or stop flow through the fuel line, a regulator adapted to at least partially restrict flow in the fuel line, and a controller operatively connected to the regulator to adjust the position of the regulator to vary the flow of fuel through the fuel line.

B62B 3/02

US Classification:

280 4734, 24828811, 24828911

Abstract:

A support comprises a device mount adapted to be connected to a user device such as a monitor. The device mount is supported on a first pivot for rotational motion about a first axis of rotation. A slide assembly comprises a carriage where the carriage is mounted for translational movement and supports the first pivot such that the first axis of rotation may be moved transversely. The support may be mounted on a technology cart comprising an upright supported on wheels where the upright supports a movable work platform. The support may be located in front of and closely adjacent to the upright where the movement of the pivot allows the user device to be rotated without interference from the upright.
