Title: Foldable utility cart with lift mechanism
Inventor: HALEY VINCENT
IPC: B62B3/10
Filed: 2001-06-05
Abstract: A foldable utility cart (10) includes a pair of spaced, parallel frame members (22). A collar (50) is disposed about each of the frame members (22) and is slidable therealong. A pair of front legs (40) and a pair of rear legs (46) are pivotally connected to the collars (50). The front and rear legs (40, 46) each support a wheel (44, 48). The collars (50) can be moved from a raised position where the legs (40, 46) and wheels (44, 48) are folded adjacent each other, to a lowered position where the legs (40, 46) and wheels (44, 48) are extended to support the cart (10) for movement on the ground. The cart (10) includes a collapsible basket (16) that is supported by a movable basket carrier assembly (18). The basket carrier assembly (18) includes toothed racks (110) that are connected to channel members (24) for movement therealong. The racks (110) are driven by pinions (132) which in turn are driven by a pulley (134) and drive belt (146) arrangement. A ratchet clutch (136) is used to permit up or down movement of the racks (110) and to maintain the racks (110), and hence the basket (16), at any desired vertical position. The cart (10) includes a handle (166) to permit the cart to be maneuvered, a brake for one or both of the rear wheels (48), a shelf (61) that extends rearwardly between the front legs (40), and a bumper (66) that extends forwardly of the front legs (40). The bumper (66) serves as a stand to prevent the cart (10) from tipping over when the legs (40, 46) are in the folded position.

Title: Method and arrangement for artillery missiles
Inventor: HELLMAN ULF
IPC: F42B10/18
Filed: 2001-06-13
Abstract: The present invention relates to a method and an arrangement for shells (1a, 1b) fired from launch weaponry, using some of the barrel pressure built up in the barrel during the launch phase for an additional active function over and above that of giving the shell (1a, 1b) in question its trajectory velocity.  According to the invention, during the launch phase, some of the propellant powder gas accelerating the shell is therefore introduced into a chamber (12, 38, 60) which is arranged in the same and which is delimited in at least one direction by an element (8, 31, 58, 52, 53) which is movable relative to the rest of the shell and on which the barrel pressure acting on the shell simultaneously acts to maintain the original direction as long as the shell is located inside the barrel during the launch phase. This technique can thus be used to remove protective casings covering the fins, in order to push out fin units and to deploy initially retracted fins.

Title: Improved method for refining vegetable oil
Inventor: BELCHER MAURICE W
IPC: C11B3/00
Filed: 1999-07-09
Abstract: The present invention relates to improved methods for refining vegetable oils and byproducts thereof. This invention also relates to an improved process for deodorizing lecithin. The invention additionally relates to deodorized lecithin and deodorized vegetable oil obtained by improved processes of the invention. In an organic acid refining process, vegetable oil is combined with a dilute aqueous organic acid solution stud subjected to high shear to finely disperse the acid solution in the oil. The resulting acid-and-oil mixture is mixed at low shear for a time sufficient to sequester contaminants into a hydrated impurities phase, producing a purified vegetable oil phase. In a lecithin deodorizing process, a phosphatide concentrate is contacted with steam in a dryer operating at a pressure below 50 mm Hg and at a temperature of less than about 150° F to form lecithin containing no more than about 0.5 percent by weight water. In a vegetable oil deodorizing process, vegetable oil is passed through a deodorizer having at least two trays and operating at a pressure of less than about 10 mm Hg. A first tray of the deodorizer operates at a temperature of about 510° F and a second tray of deodorizer operates at a temperature of about 450° F.
