Patent number: 6539853Abstract: A press that includes a push rod (12) that can be pushed downward to cut and mold miniature components, has a small size and a minimum number of components, and can be easily and precisely controlled. The push rod has a largely upwardly-facing shoulder (140) that lies in a chamber that can receive pressured hydraulic fluid to push down the push rod. A piezoelectric actuator, or piezoactor (18), moves a piston (20) that lies in a pressure cylinder. One end of the pressure cylinder holds hydraulic fluid (130), and when the piezoactor pushes the piston it pressurizes the hydraulic fluid therein. Pressured hydraulic fluid in the pressure cylinder flows through a passage (23) to the rod chamber to press down the push rod. The cross-sectional area of the pressure cylinder is many times greater than the cross-sectional area of the push rod shoulder so slight movement of the piezoactor is magnified many times by the hydraulic fluid to move the push rod with a long stroke.Type: GrantFiled: November 3, 2000Date of Patent: April 1, 2003Assignee: ITT Manufacturing Enterprises, Inc.Inventors: Achim Hess, Martin Gollhofer, Klaus Siegert

Patent number: 6539877Abstract: An elevated transit vehicle (12) is mounted on vertical wheel supports (16) which operate in curbways (40) along public streets (24). The height of the passenger cab (12) is great enough to permit conventional passenger cars (32) to move beneath the transit vehicle. The curbways block movement of passenger vehicles (32) into the space (46) between the curbways except at traffic intersections where the curbways terminate. The elevated transit vehicle operates across traffic intersections without the aid of the curbways, and other smaller passenger vehicles (32) can enter or exit from between the curbways (40) at these gaps between segments of the curbways. An inter-modal version of the transit vehicle utilizes both the wheel assemblies and a suspended railway (74) which carries the transit vehicle on rail wheels.Type: GrantFiled: September 9, 1999Date of Patent: April 1, 2003Inventor: Stanley S. Saunders

Patent number: 6539878Abstract: A rail road car has a deck for carrying wheeled vehicles. The vehicles can be circus loaded over sets of movable bridge plates extending between the rail road car and adjacently coupled rail road cars. A transition plate system is provided to span the space between the end of the deck and the bridge plate. The transition plate system includes a crank assembly that is operable to lift transition plates, permitting the bridge plates to be moved to a cross-wise position, or to an extended position. Raising the transition plates also facilitates coupling of cars by raising the transition plate out of the way of an incoming bridge plate toe of an adjacent car. The incoming toe is able to cause the opposite transition plate to be lowered.Type: GrantFiled: August 29, 2000Date of Patent: April 1, 2003Assignee: National Steel Car LimitedInventors: Ilario A. Coslovi, James W. Forbes

Patent number: 6539879Abstract: A shelf system comprising a shelf plate having a length defined by a longitudinal axis and a width defined by a latitudinal axis. A series of ribs are molded into the plate on its bottom face. These ribs are offset from the longitudinal axis and the latitudinal axis so that they intersect these axes at non-right angles, preferably forming diamond shaped patterns on the underside of the shelf plate. These diamond shaped patterns are designed to increase the strength of these shelves with a minimal amount of support material.Type: GrantFiled: September 10, 1999Date of Patent: April 1, 2003Assignee: Garagetek, Inc.Inventors: Wayne A. Current, Hal Martin

Patent number: 6539880Abstract: A sheet of corrugated paperboard formed into eleven panels, with a central panel, two end panels, and eight intermediate panels, that are interconnected at fold lines so that the sheet can be folded to form a rail for withstanding a load. The sheet can be folded to form a rail with only six vertical support panels and two diagonal support panels, only two folds against the prevailing fold direction, and only three glue areas. Also, the sheet has openings that, when the sheet is folded into the rail, align to form channels for receiving forklift arms.Type: GrantFiled: June 27, 2001Date of Patent: April 1, 2003Inventor: Walter Brian Simms

Patent number: 6539881Abstract: A pallet and an associated method are provided for supporting an item mounted upon casters. The pallet includes a pallet deck having a fixed portion and a movable portion. The movable portion moves between a first position in which the movable portion is displaced, such as by being rotated downwardly, from the fixed portion and a second position in which the movable and fixed portions cooperate to define a support surface. The movable portion is in the second position while the item is loaded, but is moved to the first position during shipment. The pallet also includes a support for supporting the item once the movable portion is in the first position. Prior thereto, however, the item is typically spaced from the support. Each support can include a stationary portion and a movable portion that moves between a retracted position to facilitate loading and an extended position during shipment.Type: GrantFiled: February 14, 2001Date of Patent: April 1, 2003Assignee: The Boeing CompanyInventors: Steven Leo Underbrink, James Robert Underbrink

Patent number: 6539884Abstract: Upon loading of oil cargo the ullage space of a tank of an oil tanker is sealed substantially gas tight with the gaseous contents of the ullage space both (i) initially inerted so as to be incapable of supporting combustion of any oil within the tank, and (ii) at an initial pressure less than atmosphere. The tank is preferably continued closed, preferably optionally with closed loop recirculation for purposes of gas mixing, for the entire voyage of the tanker save that (1) ullage space gas pressure uncommonly exceeds limits because of any of (i) leakage of atmospheric gases into the tank, and/or (ii) outgassing of gases within the oil contents of the tank, (iii) evaporation of the oil or portions thereof, and/or (iv) expansion of the ullage space gases upon thermal heating, and/or (2) free oxygen within the ullage space gases exceeds limits because of any leakage of atmospheric gases into the tank, at which time the tank is re-inerted, preferably with flue gases, or again de-pressurized, as and when required.Type: GrantFiled: May 25, 2001Date of Patent: April 1, 2003Assignee: MH Systems CorporationInventors: Mo Husain, Henry Hunter

Patent number: 6539885Abstract: An improved shackle apparatus and a locking mechanism for the same. The shackle is of a thimble type design and includes a locking mechanism for locking the shackle open and closed. The shackle apparatus allows for secure locking, easier operation, higher strength and less susceptible to problems of wear. The locking mechanism includes a plunger pin connected to a knob that mates with the shackle body to prevent the plunger pin from rotating and/or retracting, and the shackle from opening. This design prevents the plunger from both rotational as well as translational movement during extreme flogging, dragging and impact to prevent accidental opening. The shackle can be operated with one hand for the inside surface of the hook is “proud” above the surface of the clevis. This arrangement transforms any force applied to the latching side of the shackle into a moment which helps the hook close and allows the plunger pin to be snapped closed with the use of one hand.Type: GrantFiled: May 25, 2001Date of Patent: April 1, 2003Inventor: Timothy Tylaska
