The invention relates to an absorber designed to absorb radiation and to transfer the energy of the radiation to a heat transport medium. To provide an absorber with high efficiency, the absorber according to the invention comprises a plurality of absorber components (32) attached to each other and having passages (42) formed therein for absorption of radiation and for suctional intake of a heat transport medium. Each absorber component (32) is provided with a dedicated mixing chamber (44) havin...

An absorber having a shell, wet tubes and cooling fluid supply and collection portions. Partition walls divide the shell into at least three zones. The wet tubes are disposed parallelly in the shell, passing through the partition walls. The opposite open ends of the wet tube locate in the uppermost and lowermost zones of the shell, respectively. The cooling fluid supply portion communicates with the open end of the wet tube to supply a cooling fluid thereto. The cooling fluid collection portion ...

For damping undesired high frequency electromagnetic oscillations on HF technology components, such as coaxial lines, waveguides and resonators, as well as for the use in resonant circuits of VHF amplifiers with high HF power electron tubes, an absorber is proposed, which can be stablely coupled in mode-selective manner, while having a negligible influence on undesired low frequency and/or other electromagnetic oscillations, while having a predetermined high-pass characteristic. Absorber element...

According to the present invention, a water absorbent material and materials to be sucked included in a water permeable bag type member form a water absorber. Thus, the water absorber is small both in weight and volume upon its transportation, and accordingly, the water absorber can be rapidly conveyed in large quantities without depending on a human power. The water absorber absorbs water upon its use to adequately satisfy a function of a form traceability for weight, volume and outline.

An energy absorber comprises a helically coiled stores of at least partially yielding material that is drawn over a roller, or two rollers on perpendicular rotational axes, and securely fixed to a base that is attached to fragile structure such as a roof so that when an external force of sufficient size is applied to the roller or rollers through a connecting attachment eye the coil together with roller or rollers moves away from the attachment to the base whilst the coiled material is deployed ...

A shock absorber with a shock absorber body having a cylinder. A piston is moveably guided in a receiving space of the cylinder. When the piston is moved, an air pressure generated in the receiving space exerts a braking force that acts on the piston. For air pressure reduction, the receiving space has at least one opening that produces an air-carrying connection between the receiving space and the environment. The shock absorber body has a simple design if the piston or the cylinder contains a ...

A shock absorber comprises first and second axially aligned cylinders (11, 21) each having a liquid filled prison chamber (12, 22), an axially displaceable piston (13, 23), received in the piston chamber (12, 22), and dampeners (14, 24) for dampening axial displacement of the piston (13, 23) through the liquid in the piston chamber (12, 22). A piston rod (1) axially extends between and into the first and second cylinder piston chambers (12, 22). The first and second axial ends (1a, 1b) of the pi...

An oxygen absorber includes an iron powder, and a first layer coated on a surface of the iron powder and formed of iron chloride through a chemical reaction. Further, the oxygen absorber includes a matrix material filled with the iron powder covered with the first layer of iron chloride. It is possible to coat the first layer on the surface of the iron powder with a second layer to obtain more uniform coating.

A case for a noise absorber including a first case member and a second case member. The first case member includes a first cable guide and a second cable guide at opposite sides and a first core housing provided therebetween. The second case member includes a third cable guide and a fourth cable guide at opposite sides and a second core housing provided therebetween. The first case member and the second case member are interlocked and a hinge arrangement movably connects one of the sides of the ...

A shock absorber (1), in particular for bicycles, has a first cylinder (2a) with a fluid chamber (3a) filled with a transmission or damping medium. An outwardly leading piston rod (6) with piston (5a) for receiving the shocks to be dampened is borne axially displaceable in the first cylinder (2a). A second cylinder (2b) that has a fluid chamber (3b) filled with the transmission or damping medium and an air- or gas-filled gas pressure chamber (4b). The fluid chambers (3a, 3b) of the first and sec...
