IPC: A23L29/10
Filed: 1998-10-07
Abstract: A novel calcium complex for the fortification of beverages and foods, especially milk, is disclosed. Fortifying complexes are comprised of a calcium source and a negatively-charged emulsifier with or without an organic or inorganic acid or a salt thereof. These complexes have been found to be particularly effective in fortifying milk and milk-protein containing beverages without coagulation of the proteins or without significantly changing the texture of the product.

Title: Degradable poly(ethylene glycol) hydrogels with controlled half-life and precursors therefor
Inventor: HARRIS J MILTON
IPC: A61K47/34
Filed: 1998-01-23
Abstract: This invention relates to hydrolytically degradable gels of crosslinked poly(ethylene) glycol (PEG) structures. Addition of water causes these crosslinked structures to swell and become hydrogels. The hydrogels can be prepared by reacting two different PEG derivatives containing functional moieties at the chain ends that react with each other to form new covalent linkages between polymer chains. The PEG derivatives are chosen to provide covalent linkages within the crosslinked structure that are hydrolytically degradable. Hydrolytic degradation can provide for dissolution of the gel components and for controlled release of trapped molecules, including drugs. Reagents other than PEG can be avoided. The hydrolysis rates can be controlled by varying atoms adjacent to the hydrolytically degradable functional groups to provide substantially precise control for drug delivery in vivo.

Abstract: La présente invention concerne une résine de polyéthylène basse densité pour stratifié, produite par polymérisation des radicaux sous haute pression. Cette résine se caractérise par une densité comprise entre 0,910 et 0,935 g/cm?3¿, un indice de fluage de 0,1 à 300 g/10 mn, et la présence d'au moins 0,4 groupes de vinyle terminaux pour 1.000 atomes de carbone. Cette résine permet de produire par moulage basse température à grande vitesse un contrecollage présentant une résistance de liaison intralaminaire élevée, ce qui évite le dégagement de fumées et de mauvaises odeurs. Cette résine, qui se prête également bien à la production, permet des économies dans la mesure où elle permet facilement de réduire les épaisseurs. Cette résine convient notamment comme matériaux pour les emballages alimentaires et les récipients.

Inventor: BEBERNES THOMAS DARYL
IPC: B62D11/04
Filed: 2000-05-09
Abstract: A vehicle has a pair of opposite drive wheels driven by a dual path hydrostatic transmission. Steering and speed/direction controls are effected by changing the displacement and/or direction of fluid flow through the pair of reversible, variable displacement pumps that are respectively coupled to fixed displacement ground wheel drive motors. The control mechanism for accomplishing steering and/or speed/direction control includes a steering rack that is caused to pivot about a fixed post in response to steering wheel movement. A first crank arm is coupled for pivoting in concert with the rack and a second crank arm is coupled for pivoting in concert with a pivot plate about a second axis, the pivot plate having a pair of connection points respectively coupled to control arms of the pair of pumps by a pair of pump control rods. The pivotal motion of the steering rack is transmitted to the pivot plate by a tie-rod coupled between the first and second crank arms. This tie-rod is parallel to a pivot support bar that swings about the fixed post in response to fore-and-aft movement of a speed/direction control lever, the pivot plate being pivotally mounted to the free end of the pivot support bar. Thus, the pivot support bar, first and second crank arms and the tie-rod cooperate to define a four-bar linkage that causes the pivot plate to retain its pivoted position about the second axis during speed/direction control so that such control is made independently of steering, and vice-versa.

Abstract: A system and method to determine in-situ stress field based on bore hole acoustic monopole and cross dipole measurements (120). A radially polarized monopole shear wave (130) is generated in a borehole. It is then determined whether the shearwave has split into shear waves. The difference in velocities between the two split shear waves is used to determine the stress induced anisotropy (110) around and near the bore hole. The difference in velocities of cross dipole shear waves and the direction of the fast shear wave are measured and used to determine the magnitude of the maximum shear stress and the maximum stress orientation of the geologic formation. A method of determining the stress velocity coupling coefficients from laborator measurements and field measurement calibration is disclosed. The effect of bore hole pressure on the field measurement calibration of determing the stress velocity coupling coefficients is taken into account. Additionally disclosed is a method for defining a stress indicator that is related to stress caused (110) rock deformation. The stress indicator can be used to determine if rock failure is impending and is usefull in sand control and bore hole stability applications.

Abstract: The symptoms of congenital heart failure are addressed in this surgical procedure for mounting a patch in the ventricle of the heart to reduce ventricular volume. Placement of the patch (81) is facilitated by palpating a beating heart to identify akinetic, although normal appearing, tissue. The patch (81) has an oval configuration facilitating return of the heart to a normal apical shape which enhances muscle fiber efficiency and a normal writhing pumping action. The patch (81) includes a semi-rigid ring (87), and a circumferential rim (93) to address bleeding. Patch placement is further enhanced by creating a Fontan neck (78), and use of pledged sutures (110). Intraoperative vascularization, and valve replacement is easily accommodated. Increased injection fraction, reduced muscle stress, improved myocardial protection, and ease of accurate patch placement are all achieved with this procedure.

Title: Method and apparatus for data compression of network packets
Inventor: QUINLAN SEAN
IPC: H03M7/40
Filed: 2001-02-07
Abstract: A method and apparatus for compressing packets that enables inter-packet compression thereby achieving greater robustness and increased compression ratios without the deleterious effects, e.g., the effect of packet loss multiplying, of prior compression schemes. More particularly, a so-called acknowledgment scheme is employed in conjunction with the specific compression algorithm such that the transmitter, i.e., sender, can limit the history used by the compression algorithm to those packets that are correctly received. In particular, a vector identifying the packets used as the history is included in the compressed packet thereby enabling the receiver to reconstruct the packet history state necessary to decompress the packet.  Advantageously, increased robustness and greater compression ratios are achieved independent of any particular one compression scheme.

Abstract: PCD and PCBN composite constructions have an ordered structure of two or more material phases that are combined together in a packed or interwoven configuration. One of the material phases is formed from materials selected from the group consisting of: polycrystalline diamond, polycrystalline cubic boron nitride; carbides, borides, nitrides, and carbonitrides from groups IVA, VA, and VIA of the Periodic Table; and mixtures thereof. Another material phase is preferably formed from a material having a degree of ductility that is higher than that of the first material phase. Example second material phase materials include those selected from the group consisting of cermets, Co, Ni, Fe, W, Mo, Cu, Al, Nb, Ti, Ta, and mixtures thereof. Example composite constructions include those having: (1) a first material phase formed from WC-Co, and a second material phase formed from Co; (2) a first material phase is selected from the group consisting of polycrystalline diamond, polycrystalline cubic boron nitride, and mixtures thereof, and a second material phase being a cermet material; and (3) a first material phase formed from polycrystalline diamond and a second material phase formed from WC-Co. Alternatively, the material phases can be formed from the same materials, only in different proportions. Woven or packed composite constructions have surface structures formed from a number of the order material phases (made from the same, similar, or different materials) that are specifically engineered (in terms of geometry, arrangement, and materials) to provide optimized, rather than compromised, performance properties.
