Inventor: WEST KENTON L
IPC: B62D25/12
Filed: 1991-02-19
Abstract: TRUCK HOOD ASSEMBLY                 ABSTRACT OF THE DISCLOSURE           A truck hood assembly of the type which opens forwardly of the truck to expose the engine compartment is provided with four bar linkages interconnecting the hood with the chassis to cause the hood, when manually pulled from the front, to first move in a horizontal orientation forwardly away from the cab, thereby releasing connections between hood and cowl, and then to pivot to a vertical orientation to expose the engine compartment.  Hood alignment apparatus connect both sides of the rear end of the hood with the cab frame, while permitting relative vertical movement therebetween, and include a bracket disposed on the hood having a horizontally rearwardly opening slot which receives a T-shaped pin therein when the hood is closed, the clearance between the head of the pin and the hood bracket providing the relative motion.  A gap seal apparatus which visually and physically closes the gap between the hood and the cowl comprises a platform-like flange disposed on the rear side of the rear transverse hood reinforcement and extending rearwardly parallel to the hood surface beyond the hood-to-cowl gap to visually close the gap.  Once past the gap, the flange turns parallel to the cowl front wall to an elastomeric weatherstrip seal therebetween which is closed by the horizontal hood closing motion provided by the four bar linkage.

Title: Dosing system and method
Inventor: PLESTER GEORGE
IPC: B67D3/00
Filed: 1990-09-19
Abstract: The present invention relates to a dosing system for dispensing a measured quantity of fluid from a vessel. The majority of prior art dosing systems rely on a venting arrangement which exposes the fluid to possible contamination and also proves unsatis-factory in handling highly viscous fluids. The present invention overcomes these deficiencies by avoiding oxygen contact with fluids and also providing a dosing system that has very low fluid wastage. The dosing system (2) has a vessel (11) for holding a fluid and a dosing device (14) for dispensing a measured quantity of fluid from the vessel. The dosing device hermetically seals the vessel and has a valve (60) with a fluid passage (62, 64), a piston (38) surrounding the valve and a cylinder housing (22) sur-rounding the piston. A pliable funnel portion (18) is provided between the vessel and the dosing device.

Title: Method of preparing metal oxide films
Inventor: DELUCA JOHN A
IPC: C23C18/12
Filed: 1991-08-08
Abstract: RD-20,728 ABSTRACT OF THE INVENTION A method for depositing dense, continuous, and adherent metal oxide films having a uniform composition is disclosed.  An aqueous solution of soluble metal nitrate salts is formed, and nebulized into an aerosol of ultrafine droplets.  A substrate having a thermal coefficient of expansion compatible with the metal oxide film is heated to about 280° to 320°C.  The aerosol is sprayed on the heated substrate at a preselected velocity that overcomes the thermophoretic repulsion from the heated substrate.  The aerosol spray is at a density that flash evaporates on the substrate to form a dense, adherent film of a desired composition without inducing cracking in the substrate.  The substrate and metal nitrate film deposited thereon are post-heated to a temperature that partially oxidizes the film so that the film adheres to the substrate, about 450° to 550° C.

Title: Pallet container
Inventor: BURGDORF MAERTEN
IPC: B65D77/04
Filed: 1991-05-16
Abstract: ABSTRACT OF THE DISCLOSURE    The invention relates to a large volume pallet container with base pallet (100), inner plastic container (12) and outer supporting casing (30). These pallet containers are usually very solidly built with stable heavy frame structures.  An economical, lightweight construction with easily disposable individual components is desirable, particularly for non-returnable containers.  To obtain a lightweight pallet container which nevertheless possesses the stiffness and strength needed to counteract the tendency to bulge when filled, the invention proposes that the upper rim of the thin-walled plastic inner container (12) be interlocked with the pulp casing, which consists of rolled kraft paper, by means of an overlapping flanged ring (46). The bottom of the pulp casing (30) is inserted in a circular groove (74) in the surface of the plastic pallet (100) and is thereby mixed in the radial direction as well.
