Assignee

Pacific Scientific Company (Yorba Linda, CA)

International Classification

B60R 2200

U.S. Classification

280806

Abstract

A belt gripping mechanism distanced from a belt payout reel including a support housing, a clamping assembly and a locking assembly, which functions in response to a predetermined load to grip a restraint belt in an effectively permanent manner so as to not be immediately releasable upon the cessation of forces which initially triggered the gripping. During emergency crash situations, the locking of the belt payout reel causes the clamping assembly to move from a locked "non-gripping" position to a locked "gripping" position significantly reducing the forward movement of the vehicle passenger.

Abstract

A filtering system for a downdraft cooking appliance includes a filter assembly arranged directly below an air grill leading to a venting plenum. The filter assembly includes a liner which supports a filter element and is removably positioned inside the plenum. The filter element can be arranged inside the liner, attached thereto or insert molded into the liner material. The liner is preferably suspended from the air grill so as to be readily removable in unison with the grill for inspection, cleaning or replacement. In a preferred embodiment, the liner is formed with opposing, outwardly projecting flanges which slide into mating channels formed into the underside of the grill. With this arrangement, exposure of the wall surfaces of the plenum to the cooking byproducts is minimized, thereby greatly reducing any necessary cleaning of these surfaces.

Claim

We claim: 1. A downdraft cooking appliance comprising: a cooktop formed with an opening; a plurality of heating elements arranged about the cooktop; a plenum including a plurality of walls disposed, at least in part, below the cooktop, said plenum having an opening disposed adjacent the plurality of heating elements; a blower exposed to said plenum for developing a venting flow of air containing cooking byproducts through the opening and into the plenum from above the cooktop during a cooking operation; a grill covering the opening, said grill having upper and lower surfaces; and a filter element suspended from the lower surface of the grill and projecting into the plenum, wherein the flow of air is directed through the filter prior to reaching the walls of the plenum in order to isolate the walls of the plenum from exposure to the cooking byproducts. 2. The downdraft cooking appliance according to claim 1, wherein the filter element is removably attached to the grill. 3. The downdraft cooking appliance according to claim 2, wherein the filter element forms part of a filter assembly, said filter assembly further including a liner supporting the filter element. 4.

Barge Hull For Offshore Drilling Rigs

Assignee

Marathon Manufacturing Company (Houston, TX)

International Classification

E02B 1708, B63B 132

U.S. Classification

405203

Abstract

An improved barge hull for offshore drilling rigs is disclosed. The invention comprises a channel in the bottom of a barge hull extending from the bottom of said barge hull to the back of said barge hull for directing the flow of water under said barge hull to the back of said barge hull in order to disrupt the relative hydrodynamic stability of a body of water immediately behind said barge hull and thereby decrease the towing resistance of said barge hull.

Abstract

A cartridge is disclosed which comprises a volume of particulate packing material through which a fluid is to flow, a piece of solid porous material adjacent to the surface of the packing material though which the fluid is to enter the volume and a second piece of solid porous material adjacent to the surface of the packing material through which the fluid is to exit from the volume, and a heat-shrinkable tubing which triaxially compress the packing material into a tightly packed bed predominantly in the directions which are normal to and parallel to the direction of fluid flow through the packed bed and which extends beyond the pieces of solid porous material to form an inlet opening to and an outlet opening from the packed bed.

Assignee

Marathon Manufacturing Company (Houston, TX)

International Classification

E02B 1700, B63B 3500

U.S. Classification

Abstract

A combination offshore drilling rig which combines the desirable features of a slot-type drilling rig and a cantilever-type drilling rig while eliminating the limitations and undesirable features associated with either type of such rigs. The combination offshore drilling rig mounts the derrick and drilling equipment on a movable cantilever structure which may be positioned over a slot of sufficient area to permit the drilling operation to be carried out through the slot or may be moved outboard of the peripheral boundary of the rig hull to perform a drilling or workover operation outside the peripheral boundary of the rig hull.
