Title: Method for making foam filled doors and apparatus therefor
Inventor: MARTINI JOHN
IPC: E06B3/70
Filed: 1999-07-09
Abstract: A method for the assembly of doors having a pair of skins and a core of synthetic resin forms a first door element including forming a first skin and a peripheral wall to provide an upwardly opening cavity into which a foamable synthetic resin formulation is introduced. A second skin is then assembled over the cavity, and the resultant door assembly is passed through an elongated heating zone while controlling the thickness dimension of the door assembly to expand and cure the resin formulation in the cavity into a cellular resin insulating core and to bond the skins and core. The several steps are conducted seriatim at stations along a conveyor assembly.

Title: Folding leg mechanism
Inventor: HAYWARD JAMES
IPC: A47B21/00
Filed: 1999-07-26
Abstract: A folding table leg mechanism for mounting to a tabletop, having a leg support with an extension portion and a base portion fixedly mounted to the extension portion, and a mounting mechanism for pivotally connecting the leg support to the tabletop. The mounting mechanism has a hinge joint for pivoting the leg support in a pivot plane substantially perpendicular to the tabletop plane from a collapsed position in which the leg support is substantially parallel to the tabletop to an erect position in which the leg support is substantially perpendicular to the tabletop, and also has a rotation joint for rotating the leg support about a rotation axis substantially perpendicular to the tabletop when the leg support is in the erect position, from a first rotational position to a second rotational position. The leg support may be locked in place when it is in the second rotational position. The mechanism may also include a cord tray pivotally coupled to the leg support wherein the cord tray pivots with the leg support when the leg support is pivoted between the collapsed position and the erect position, but wherein the cord tray remains fixed in position relative to the tabletop when the leg support is rotated between the first rotational position and the second rotational position.

Title: Method for determining sedimentary rock pore pressure caused by effective stress unloading
Inventor: HOLBROOK PHILIP W
IPC: E21B49/00
Filed: 1998-04-27
Abstract: An improved technique to more accurately calculate pore pressure of sedimentary rock due to subsurface fluid expansion. The technique is built upon a combinations of known force balanced in situ loading limb mineralogical stress/strain relationships with locally variable unloading stress/strain relationships (S, P). In stress/strain space, the material properties governed loading limb is and upper limit for the many possible unloading limbs. A method for relating these different natural stress/strain paths and applying the correct path to calculate pore fluid pressure from in situ force balance is preferably calibrated with in situ stress/strain data which allows for a lithologic sealing caprock, shale (16) to be identified and the locally prevailing in situ unloading limb stress/strain relationship to be estimated. The forced balanced loading and unloading calibrations are applied to more accurately determine well casing depths while drilling petrophysical data. Loading and unloading power law linear stress/strain relationships are determined between effective stress and solidity for common sedimentary rocks.

Such modifiers can be selected from the group consisting of atactic polypropylene, syndiotactic polypropylene, ethylene-propylene copolymer, propylene-butene-1 copolymer, ethylene-propylene-butene-1 terpolymer, and linear low density polyethylene. The skin layer can be high density polyethylene or ethylene-propylene-butene-1 terpolymer. A metallized layer, such as aluminum, is deposited on the corona treated skin layer.

Title: Entropy pump for medical purposes and a modified syringe
Inventor: MAYHEW KENT W
IPC: A61M1/36
Filed: 2000-01-27
Abstract: The present invention is an apparatus designed to remove of dissolved gases from liquids. More specically the present invention has a medical application for removing unwanted dissolved gases from a patient's blood. The present invention removes the dissolved gases by isolating the patient's blood in a chamber and then forcing the chamber to expand. The process of forced expansion of the chamber allows the gas molecules dissolved in the blood to attain enough entropy to change to a gaseous state.     One application is the present invention can be used by doctors to removed dissolved nitrogen from the blood of a patient afflicted with the bends. This maybe used with a hyperbaric chamber or on the present invention maybe used on it's own.    The bends tend to accumulate in the spine, exterior fat and joints of scuba divers afflicted with the bends. The present invention has the advantage over a hyperbaric chamber, in that unlike the hyperbaric chamber, the present invention can be site specific.

Title: Process for the preparation of oxazaphosphorine-2-amines
Inventor: KUTSCHER BERNHARD
IPC: C07F9/6584
Filed: 1998-08-14
Abstract: The present invention relates to a method for preparing oxazaphosphorin-2-amines of the general formula (1), wherein R1 may represent H, 2-bromethyl, 2-chlorethyl, 2-hydroxyethyl, 2-mesyloxyethyl or 1-phenylethyl, R2 may represent H or 2-chlorethyl, R3 may represent H, 2-bromethyl, 2-chlorethyl or 1-phenylethyl and R4 may represent H. R1 and R2 as well as R3 and R4 may also form together with the linked N-atom a cyclic aziridin compound with the proviso that R1, R2 and R3 cannot represent simultaneously H and that R1 and R3 cannot represent simultaneously 1-phenylethyl. Y represent hydrogen hydrochloride or bromide or nothing. The compounds obtained using this new method are known drugs such as cyclophosphamide and ifosfamide which are used as cytostatic or immuno-suppressing agents. The amines (2) and (3) used as starting compounds are reacted during a single-vessel reaction with phosphoryl chloride and with an additional base used as an acid-fixation agent such as pyridine, triethylamine or alkaline or earth-alkaline carbonates. The reaction is carried out in the presence of inert solvents while reducing to a minimum the influence of water and without isolating an intermediate compound.
Patent CA-2301380-A1 (CA)
Title: Device and method for advertising and carrying bags with handles
Inventor: BOZLEE MARTIN
IPC: A45F5/10
Filed: 2000-03-20
Abstract: The handle of the present invention is formed from a sheet of pliable material having a periphery with two opposed convex edges separated by two opposed concave edges. Two parallel fold-lines join the concave edges. When the sheet is folded, the body forms symmetrical walls that are fastened together using a tab, located on the edge of one symmetrical walls of the handle, and groove formed on the edge of the second symmetrical wall of the handle, for receiving the tab. In its folded state, the handle resembles a taco shell with a bite taken from each end. The bite resemblance is formed by the two opposing concave edges and help to limit the length of the flat base formed by the space between the parallel fold lines. A correct base length allows the bag handles to naturally droop from the weight of the contents, so that the taut bag handles do not cut through the pliable body material or weaken the base. The design of the present invention allows for unobstructed advertisement on both outside surfaces of the handle as well as on both inside surfaces of the handle. Additionally, two separate entities can advertise on a single handle device. The present invention also solves the market penetration problem experienced with low margin grocers and other stores. Because advertising revenue is generated by the seller of the handles, the seller can penetrate the market by giving the handles away freely to grocers or other stores that use plastic bags.
