Abstract: The invention provides food products, including confectioneries and chocolates, having conserved concentrations of polyphenols, and in particular cocoa polyphenols. The method of this invention avoids the significant and detrimental polyphenol losses that occur during conventional manufacture by controlling the handling of ingredients in the batching process to provide a product containing a significant amount of the cocoa polyphenols present in the raw materials used to formulate the finished product. Additionally, the milling/refining and conching steps may also be controlled and modified to provide confectioneries having conserved concentrations of cocoa polyphenois relative to the cocoa polyphenol-concentration of the starting ingredients. The cocoa polyphenol containing ingredient may be a cocoa extract, chocolate liquor, partially defatted cocoa solids, and/or synthetic polyphenol.

Title: Dry foodstuff dispenser
Inventor: WALDMAN HAROLD
IPC: B65D83/06
Filed: 2002-01-08
Granted: 2010-05-25
Abstract: A dispenser for storing and dispensing dry foodstuffs includes a hopper and a free flow ball-type dispensing mechanism. The hopper chamber is configured for store shelf use having planar front and side panels. An exit orifice is formed in a lower portion of the hopper and most preferably at a lower front portion. The dispensing mechanism is positioned over the exit orifice and is selectively operable to regulate the dispensation of foodstuffs to the consumer. The dispensing mechanism is characterized by a covering housing and an internal gate mechanism. The covering housing includes a generally semi-spherical portion with an opening therethrough and an anchoring flange. The covering housing is secured over the hopper exit orifice such that foodstuffs move downwardly from the hopper chamber under gravity, through the exit orifice and into the interior of the semi-spherical portion of the covering housing. The gate member is selectively movable relative to the semi- spherical portion between a position where it substantially overlies and blocks an outlet opening in the semi-spherical portion to prevent movement of foodstuffs therethrough, and an open position wherein the gate member is moved at least in part therefrom, permitting the free flow of foodstuffs from the interior of the covering housing outwardly through the opening. A handle secured to the gate member projects outwardly through a slot formed through the covering housing where it may be grasped by a user, and wherein the slot extends in a plane which is generally perpendicular to the lateral width of the hopper to which the ball dispenser is mounted.

Abstract: Dominant-negative alleles of human mismatch repair genes can be used to generate hypermutable cells and organisms. By introducing these genes into mammalian cells new cell lines with novel and useful properties can be prepared more efficiently than by relying on the natural rate of mutation or introduction of mutations by chemical mutagens. These methods are useful for generating novel and highly active antimicrobial molecules as well as superior antimicrobial agents from pre-existing chemicals. These methods are also useful for generating cell lines expressing novel antimicrobials that are useful for pharmaceutical manufacturing.

Abstract: Cet extrait concerne un système de mise à niveau de véhicule comprenant au moins un capteur de niveau, un contrôleur et une sortie. Le capteur mesure le degré de niveau du véhicule par rapport à l'horizontale. En option, il le fait dynamiquement, alors que le véhicule se déplace sur une aire de stationnement potentielle. Le contrôleur analyse les mesures du capteur, et informe l'opérateur via la sortie si le véhicule est de niveau dans une direction donnée, si la mise à niveau du véhicule progresse, si le véhicule peut être mis à niveau à un endroit donné, et/ou la « meilleure » mise à niveau dont le système est capable à un emplacement donné. Le système peut également effectuer automatiquement la mise à niveau du véhicule par rapport au sol pour l'opérateur. Dans un mode de réalisation, le système de nivellement communique avec un système de commande de hauteur de véhicule électronique existant. Le système de nivellement remplace ou contrôle le fonctionnement normal de ce système, et l'utilise pour effectuer la mise à niveau du véhicule, par exemple, en ajustant la suspension du véhicule.
