Abstract: A slidable room assembly (20) comprises a vehicle body (22) having an opening formed in an exterior wall, and a reciprocable slideout unit (24) or compartment (26) in the opening and slidable between a retracted position and an extended position. Sliding movement of the slideout unit is controlled by means of a drive mechanism which includes either one or two endless cables (62, 64). A plurality of sheaves (100), rotatably mounted on the slideout unit, define a path for the endless cable or cables. This path includes a pair of parallel longitudinally extending courses disposed on opposite sides of the slideout unit. Anchors (8) attached to respective longitudinally extending courses of the cable(s) and to adjacent portions of the vehicle body, effect relative reciprocation between the slideout unit and the vehicle body.

Title: Method for transforming cariogenic food sugars into acariogenic or cariostatic neutral products and composition therefor
Inventor: DANA JEAN-DOMINIQUE
IPC: A61K8/66
Filed: 2000-12-19
Granted: 2011-10-11
Abstract: The invention concerns a method for transforming food sugars, which acts in two ways: directly and indirectly. Said method is characterised in that the main direct action consists in inhibiting glycolysis by transforming the cariogenic polyoses into non-cariogenic polyols (for example, sorbitol); the indirect action consists in the use of products derived from the polyose degradation as substrates by the inventive enzymatic system so as to reinforce prevention of plaque formation, through five mechanisms: stimulating saliva flux with the polyols; reinforcing the saliva antibacterial power by activating the physiological lactoperoxidase/hypothiocyanate system with hydrogen peroxide; decreasing the number and pathogenicity of the bacterial environment stabilising .delta.-lactones, which are not bacterial substrates for plaque formation; remineralizing the enamel by stabilising the calcium phosphate solution with sorbitol. The invention is applicable to bucco-dental hygiene.

Abstract: A cooking appliance includes a gas burner element, at least one electric heating element and a convection airflow system having a convection fan about which is disposed the at least one electric heating element. A control unit selectively activates the gas burner, the electric heating element and the convection fan to establish a desired temperature within the oven cavity. Once established, the control unit then cycles operation of the gas burner and electric heating element to maintain the desired temperature. With this arrangement, in a start-up period during which products of combustion are highest, operation of the electric heating element aides in the combustion process to reduce emissions from the appliance, as well as causing a reduction in overall cook time.

Title: Improved method of hydraulic fracturing to reduce unwanted water production
Inventor: WOOD WILLIAM DALE
IPC: E21B43/26
Filed: 2004-06-18
Granted: 2008-05-13
Abstract: A method of hydraulically fracturing a hydrocarbon-bearing subterranean formation ensures that the conductivity of water inflow below the productive zone of the subterranean formation is reduced. The method consists of two principal steps. In the first step, a fracture in and below the productive zone of the formation is initiated by introducing into the subterranean formation a fluid, free of a proppant, such as salt water, fresh water, brine, liquid hydrocarbon, and/or nitrogen or other gases. The proppant-free fluid may further be weighted. In the second step, a proppant laden slurry is introduced into the subterranean formation which contains a relatively lightweight density proppant. Either the fluid density of the proppant-free fluid is greater than the fluid density of the proppant laden slurry or the viscosity of the proppant-free fluid is greater than the viscosity of the proppant laden slurry. The method limits undesirable fracture height growth in the hydrocarbon-bearing subterranean formation during the fracturing.
