Granted: 2004-07-20
Abstract: La présente invention concerne un procédé de fabrication de beurre d'arachide à teneur réduite en matière grasse et donc hypocalorique. Dans un mode de réalisation, le procédé consiste à préparer un mélange de farine d'arachide contenant entre environ 5 % et 35 % d'huile d'arachide et un polyester d'acide gras de polyol ayant au moins quatre groupes hydroxyle estérifiés. Le polyester de polyol est présent dans le mélange à raison d'environ 10 % à 25 % en poids, ce pourcentage étant calculé sur le poids de farine d'arachide. Le mélange est broyé pour produire une pâte d'arachide, laquelle est mélangée avec un complément de polyester d'acide gras de polyol ayant au moins quatre groupes hydroxyle estérifiés. On obtient ainsi un beurre d'arachide ayant une teneur totale en matière grasse d'environ 45 % à 55 % en poids, mais avec une teneur réduite en graisse digestible.

Patent CA-2197187-C (CA)
Inventor: BEST BERND
IPC: C11C3/10
Filed: 1995-08-12
Granted: 2007-03-27
Abstract: The extraction of native products is rendered difficult by the fact that attraction forces act between the liquid native products which are not water-soluble and the tissue incorporating them, and that other constituents are dissolved or present in the form of particles in suspension in the products during the extraction process. The initial substance mixture is, therefore, processed together with a water-soluble, organic solvent and optionally water to form a paste. The addition of the water-soluble, organic solvent enables the substance mixture to be separated cleanly into an aqueous phase and an organic phase in the centrifugal field, no further cleaning being necessary for the organic phase. The process according to the invention has a wide area of application.  In principle, it can be applied to all substance mixtures containing liquid, organic substances, in particular to vegetable and animal tissue. It is suitable for extracting oils from oleaginous fruit or waxes from wax-containing plants, as well as for extracting fish oils.

Granted: 2004-02-10
Abstract: A consumer digital video cassette recorder (210) may record an advanced television signal (09) having an MPEG-like signal format. The predictive nature of the MPEG-like signal format requires that additional I frame data (51, 61, 71) be generated and recorded together with a normal play speed data stream (10) to facilitate non-standard speed, or trick play reproduction. Additional I frame data streams (51, 61, 71) are generated specifically for each replay speed and are written within recorded tracks to facilitate reproduction at the predetermined speeds. Various inventive methods for the derivation of full resolution and reduced resolution trick play data streams are disclosed. Inventive trick play data stream generation is disclosed for real time recording by consumer apparatus and non-real time normal and trick play data stream generation for use with pre-recorded digital media.

Abstract: A method and system for evaluating health care provider performance, forecasting health care resource consumption on a macroeconomic scale, and optimizing the allocation of health care resource. The method includes the steps of: a) providing patient discharge data which includes an address field indicating one of a plurality of micro-geographical areas (MGAs) wherein a patient resides, b) establishing a referral population for a subject health care provider based upon the market share it has for each cohort in each MGA, c) calculating occurrence rates of medical service demand for the referral population, d) providing an applying population growth factors to the referral population thereby projecting it to a future time, e) applying the occurrence rates to the projected referral population thereby forecasting the consumption of health resources, and f) allocating health care resources including changing space, hiring and transforming staff and purchasing equipment and other resources, in accordance with the forecast. The invention can also factor into the forecast the expected caseload demand from undeveloped or proposed communities. In addition, the invention optionally computes repatriatable caseload volume, i.e. medical service demand which has gone to another health care provider but could be handled by the subject health care provider, and adds this volume to the forecast. Finally, the invention provides for a method for efficiently allocating health resources amongst neighbouring health care providers, based on either current or forecasted medical service demand data.
