Filed:

Mar 21, 2006

Appl. No.:

11/385971

Inventors:

Hendrik W. Grobler - Clyde Park MT, US

International Classification:

B62D 55/04

US Classification:

180 921, 180 928, 180 93, 180 934, 180 936, 180 938

Abstract:

A motor vehicle with an additional crawler undercarriage includes assemblies to reduce the load pressure transferred to the ground and to improve off-road performance. The assemblies include components used in conventional mass-produced vehicles, with a chassis (), a body with optional cargo area (), undercarriage, such as axles () with steered () and/or unsteered wheels (), tires (), wheel suspension, spring support, steering and brakes, and an engine-transmission unit () with drive components. An additional crawler undercarriage () can be mounted and/or retrofitted on the chassis () between the axles () and used for traction in any terrain. The additional crawler undercarriage () includes an undercarriage () with drive wheels () and carrying wheels () and revolving crawler chains/crawlers () and associated elements, first means () for providing an optionally extendable and retractable connection of the undercarriage () with the chassis (), and second means () for selectively transmitting or coupling a second drive from the motor vehicle to the additional crawler undercarriage (), as well as third means () for controlling the operation of the additional crawler undercarriage (), such as steering, braking, acceleration and speed of the crawler chains/crawlers ().

International Classification:

F27D 19/00

US Classification:

219392

Abstract:

A heating element arrangement for a vacuum heat treating furnace is disclosed wherein the heating elements that make up the heating element arrays have different electrical resistances or watt densities at different locations in the heating element arrays. This arrangement allows for placement of heating elements having electrical resistance selected to provide more or less heat as needed in the furnace hot zone to provide better temperature uniformity in the workload. The electrical resistances and watt densities of the heating element arrays are varied by using a first heating element having a geometry in one segment of a heating element array and a second heating element having a different geometry from that of the first heating element in another section of the heating element array.

F27D 3/00

US Classification:

266 44, 414160, 266114, 266259

Abstract:

A load transport mechanism for moving a heat treating load in a multi-station heat treating system is disclosed. The transport mechanism has a compact construction that allows it to fit in a centrally located stationary transport chamber. The transport chamber is adapted to provide ready access to multiple treating chambers arrayed around the chamber. The transport mechanism includes a load translation mechanism for moving the load linearly and a load rotation mechanism for rotating the load within the transport chamber. A multi-station heat treating system having a centrally located quenching chamber that includes the load transport mechanism is also disclosed.

International Classification:

F27D 9/00

US Classification:

432 85, 432 77

Abstract:

A quenching apparatus is disclosed which has a generally cylindrical base and upper housing. A removable cover is affixed to the top of the upper housing. The quenching apparatus includes means for supporting the removable cover above the upper housing such that a passageway is defined between the upper housing and the removable cover. A generally cylindrical door is dimensioned and positioned within the quenching apparatus to be coaxial within the upper housing and the base. An actuator is coupled to the cylindrical door for moving the door between an open position and a closed position. In this manner, the door is adapted for closing the opening between the base and the upper housing and thereby provides a closed quenching chamber. Redundant retractable seals are provided in the base and the upper housing to seal the door to the upper housing and the base when the door is closed.
