  • Patent number: 9560881
    Abstract: Disclosed is a smokeless cigarette system comprising a reusable cigarette tube and a nicotine stick which can be discarded after use. The nicotine stick comprises a depot filter charged with a nanobead solution and nicotine and flavor substances attached thereto or incorporated therein, and a mouthpiece filter, which are joined together and produced at the factory stage. The disclosed smokeless cigarette is particularly suited for use in non-smoking areas to prevent stress caused by nicotine withdrawal and as a cigarette substitute, but can also be used in different types of cigarettes with varied dosage strengths to ensure gentle nicotine withdrawal and smoke disintoxication. Neither the environment nor other persons are harmed of put at risk by this system by either passive smoking or the generation of odour. The system can be handled in a simple and unproblematic manner since no heat source or heating systems are required.

  • Publication number: 20110214518
    Abstract: The invention relates to a functional part of an electronic piston stroke pipette with an operating environment adapted to manual piston stroke pipettes. The piston stroke pipette according to the invention comprises a pipette cone, in which there is a movable piston, rigidly connected with a transmission for its upwards and downwards movements via a piston rod, in which context the transmission is propelled by a drive motor and wherein the control board comprises an upper part as the operating part for turning and pressing and a bar as a cylindrical connection to the electronics, with the control board and display integrated in the display housing in the upper part and drive motor and battery (rechargeable battery) in the lower part of the pipette housing. Fields of application of the invention are analytical chemistry and medicinal diagnostics.

  • Publication number: 20100059073
    Abstract: The invention relates to a novel smokeless cigarette system comprising two parts: a reusable cigarette tube (1) and a nicotine stick (5) which can be discarded after use. The nicotine stick (5), comprising a deposit filter (2) that is charged with a nanobead solution (4) and nicotine and flavour substances attached thereto or incorporated therein, and the mouthpiece filter (3) are joined together and produced at the factory stage. All parts closely reproduce a cigarette as detailed as possible in terms of their outer appearance, design, dimensions, draw resistance during use, taste and nicotine absorption. According to the invention, the smokeless cigarette is particularly suited for use by smokers in non-smoking areas in order to prevent stress caused by nicotine withdrawal and as a cigarette substitute, but can also be used in different types of cigarettes with varied dosage strengths to ensure a gentle (slow) nicotine withdrawal and smoker disintoxication.

  • Patent number: 4845721
    Abstract: A solid state laser comprises a laser element formed from crystalline, ceramic, glass ceramic, glass, or plastic material in the configuration of a rod or slab. The cooling capabilities of the rods or slabs are improved by the provision of internal bores or slots through which a coolant can flow, and/or by the provision of a modified cross-sectional profile whereby the cooling surface is increased and the distance between the interior regions of the rod or slab and the cooling surface is reduced. Alternatively, the cooling capacity of the laser system is improved by providing a rotating arrangement of laser material wherein only specific portions of the laser materials are subjected to pumping while other portions are cooling.
