  • Patent number: 11047567
    Abstract: A steam generator and a method for generating steam, the generator comprising a steam chamber fed with water from a water from a water reservoir for heating by a heating source to generate steam, steam being delivered out through a steam outlet, and waste water being evacuated through a drain, the steam generator comprising a control chamber, in fluid communication with the steam chamber so as that a water level in the control chamber is indicative of a water level in said steam chamber; at least one water level-sensor configured for detecting the water level in the control chamber; and a control unit receiving a signal from the water level-sensor. There is further provided a method of generating steam in a steam chamber receiving Water is fed from the water reservoir simultaneously to the steam chamber and to the control chamber, through a single feeding valve, the feed water being mixed with hot waste water drained from the steam chamber, upstream of a drain pump.

  • Publication number: 20150136272
    Abstract: This dosing device (1) comprises a container (2) and a plug (4) comprising, in addition to a part (15) for connection to the container, two mobile outer parts (16 and 17). One of the mobile parts (16) is held in place during dosing, while the container (2) rotates continually to assist the flow of the content of same; the other outer part (17) can be rotated as necessary to adjust the opening of the plug. The movements can be carried out by a machine on which the dosing device is positioned upside down, with the plug facing downwards.

  • Patent number: 4961890
    Abstract: A process for preparing a controlled release medicine containing fenofibrate in an intermediate layer in the form of cyrstalline microparticles included within pores of an inert matrix prepared by a process involving the sequential steps of dampening said inert core with a solution based on said biner, then projecting said fenofibrate microparticles in a single layer onto said dampened core, and thereafter drying before said solution based on said binder dissolves said fenofibrate microparticles and repeating said three steps in sequence until said intermediate layer is formed.

  • Patent number: 4960596
    Abstract: The slow release preparation obtained by the method of the invention reduces the number of times the medicine needs to be taken per day, and also provides lower peaks of concentration in the blood after the medicine has been taken while simultaneously ensuring that the lowest concentration in the blood remains higher over a period of time.
