Title: Apparatus and method for producing aerated confectionery masses
Inventor: SIMBUERGER STEPHAN
IPC: A23G1/10
Filed: 2005-12-19
Granted: 2013-07-09
Abstract: For producing an aerated confectionery mass, a raw confectionery mass is fed at a feed rate from a supply (10, 12) to an aeration unit (18) for introducing gas into the confectionery mass and wherein the aerated confectionery mass is fed to a production line (32) for the production of confectionery or tablets. The feed rate of the raw confectionery mass is controlled such that it corresponds to the demand of the production line (32), the amount of introduced gas is controlled in response to the feed rate of the confectionery mass so that the aeration level of the confectionery mass remains substantially constant and the temperature of the aeration mass within the aeration unit (18) is controlled such that it remains substantially constant and independent from the feed rate. The aeration unit (18) may include a rotor for stirring and kneading the confectionery mass containing the introduced gas, the rotational speed of the rotor being controlled such that it is enhanced for higher feed rates and reduced for lower feed rates in order to produce gas bubbles of approximately the same size independent from the feed rate. In order to keep the bubble size small during the depositing step, the depositing is realized via a pressurized manifold containing multiple nozzles.

Abstract: A self-teaching lower limb prosthesis, for an above-knee amputee, including a dynamically adjustable joint movement control unit arranged to control operation of the joint automatically. A control unit electrically stores a target relationship between a kinetic or kinematic parameter of locomotion and walking speed. The relationship defines a number of values of the parameter associated with different walking speeds. The control unit generates monitoring signals representative of walking speed values and values of the parameter occurring at different walking speeds. An adjustment system adjusts the control unit automatically when the monitoring signals indicate deviation from the target relationship so as to bring the parameters close to that defined by the target relationship.

Abstract: La présente invention concerne des huiles aromatiques comprenant des arômes de type arômes de menthe, de fruit et d'épice, lesquelles sont spécialement traitées pour éliminer sensiblement les composés du soufre de faible poids moléculaire, en particulier le diméthylsulfoxyde (DMSO), dont on a trouvé qu'il était le principal précurseur de substances malodorantes telles que le sulfure de diméthyle et le méthylmercaptan. Ces substances malodorantes sont produites via des réactions d'oxydoréduction impliquant de tels composés contenant du soufre présents dans les huiles aromatiques. Un procédé de lavage aqueux est un procédé de traitement préféré, lequel présente les avantages d'être simple, bon marché et facile à mettre en AEuvre tout en évitant en grande partie les problèmes de procédés typiques tels que l'élimination non sélective de composants désirables et le fait de soumettre les huiles aromatiques à des conditions extrêmes qui peuvent détruire d'autres composants et entraîner des changements indésirables en termes de caractère de l'odeur et de l'arôme. D'autres procédés de traitement pour enlever sélectivement les composants indésirés comprennent (1) la distillation pour enlever les composants polaires de faible point d'ébullition, (2) la filtration sur des adsorbants sélectifs vis-à-vis des composés du soufre, (3) l'extraction à contre-courant et (4) la chromatographie sur colonne. Les procédés de traitement peuvent éventuellement être suivis d'une reformulation pour rajouter des composants désirés qui peuvent avoir été enlevés ou altérés au cours du traitement. Les huiles aromatiques spécialement traitées sont particulièrement utiles dans des compositions d'hygiène bucco-dentaire comprenant des composants ayant une aptitude chimique réductrice tels que les ions stanneux, lesquels réagissent avec les composés contenant du soufre pour produire des produits malodorants.

Abstract: A positive displacement pump apparatus (10) is disclosed for displacing a pumping fluid. The apparatus comprises one or more pump chambers (22) arranged in a pipe system for receiving the pumping fluid, the pipe system having at least one inlet (21') which can be shut off by means of a valve (24'), and at least one outlet (21") which can be shut off by means of a valve (24"). The one or more pump chambers 22 are connected via at least one intermediate fluid chamber (13") with at least one displacement element in the form of a piston head (14) and a piston rod (15), which is arranged to alternately carry out a suction stroke and a displacement stroke during its movement so as to displace fluid in the intermediate fluid chamber (13"), which thereby increases and reduces, respectively, the volume of the pump chamber (22). At least one flexible separating element in the form of a diaphragm (23) is provided at the pump chamber (22) to separate the fluid in the intermediate fluid chamber (13") from the pumping fluid. Furthermore, a force means is provided for applying force or energy to a side of said at least one piston head (14) at least during the displacement stroke, in such a manner that said force or energy counteracts the force exerted on the piston head (14) by the fluid in the intermediate fluid chamber (13"), which can thereby reduce the overall force needed to carry out the displacement stroke movement of the piston head (14) and a piston rod (15).
