Abstract: A method for break separation of pieces that can be re-assembled or their starting materials achieves a break separation at a selected break surface. The method includes subjecting a piece to be subjected to break separation to a break force F3, F3? perpendicular to the selected break surface. Also, the method includes applying, before the time at which the piece is subjected to the break force F3, F3?, a compressive force F1-F6? to the piece in a manner such that a tensile stress is produced whose maximum occurs perpendicular to the plane of the break surface, the level of stress produced is below the elastic limit of the material of the piece, and the compressive force F1-F6? continues at least until the piece is first subjected to the break force F3, F3?.

Abstract: A photosensitizer that is excitable via infrared radiation and is adapted to be used to treat a selected biological target. The photosensitizer comprises a core nanoparticle adapted to convert infrared radiation into a visible light emission, and a coating disposed about the core nanoparticle. The coating contains a light excitable agent that is adapted to be excited by the visible light emission from the core nanoparticle. The photosensitizer can be surface modified with an antibody to make the photosensitizer specific to the biological target that is to be treated. Such surface modified photosensitizer is introduced to the target site and irradiated with infrared radiation.

Abstract: A manually guided implement having a tool driven by an internal combustion engine, which draws combustion air in via an air filter disposed on an air filter base. The air filter is secured to the implement via a releasable securement device that includes a first securement element, and a second securement element that cooperates with the first securement element. The securement elements can be released from one another, or connected to one another, by means of a rotational movement about an axis of rotation. To achieve easy handling of the air filter, the first securement element is fixedly connected to the air filter.

Abstract: An apparatus for heating and melting solid lubricants in a delivery drum, including a heating element composed of armored resistors shaped as concentric rings and junction spokes. A hoist lowers and raises the heating element into and out of the drum via vertical rods that are not heated. A first thermal sensor is connected with the heating element, and a second thermal sensor is mounted on the vertical rods. A transfer pump withdraws melted lubricant from the drum via a suction tube having a bottom valve at its foot. A lubricant delivery tube is connected to the output side of the pump.

Abstract: An apparatus for the gasification or aeration of liquids. Elongated aeration elements are connected to a distribution conduit and have an essentially rigid support tube having a lengthwise rounded groove about which is disposed a membrane of elastomeric material. Compressed gas introduced between the support tube and membrane escapes via slits in the membrane. An elastically deformable flange of a cylindrical portion of a fitting with a plastic semi-rigid saddle portion is disposed between the distribution conduit and one of the aeration elements, and is disposed in a bore in the conduit. The fitting has an essentially flat saddle portion, one side of which rests against the outer surface of the conduit, and the other side of which rests against an end of the aeration element. A hollow bolt is securely connected to the aeration element and is guided through a bore in the fitting into the interior of the conduit, where it is provided with apertures.

Air inlet openings of the cylinder head are connected to the first chamber in a gastight manner. The charged air conduit has at least one second chamber, which is separate from the first chamber and has a removable lid. The fuel reservoir is secured in the second chamber, which is provided with a first passage allowing the high pressure fuel line and the fuel reservoir to communicate with one another. The second chamber has at least one second passage, facing the cylinder head, allowing the fuel injection lines and fuel connections on the cylinder head to communicate with one another. With the lid in place, the second chamber encloses the fuel reservoir, the fuel injection lines and the fuel connections such that in the event of leakage at any of them, leaking fuel flows into the second chamber.
