    摘要: A roller for moving equipment such as furniture has a wheel whose wheel disk is provided with a rim having a pair of outwardly extending flanges. The tire mounted on this rim has an inner portion wholely received between the flanges and an outwardly portion lying wholely outwardly of the flanges. The inner portion is provided with such bores in angularly equi-spaced relationship and wholely within the circumference of the flanges so as to be closed therebetween. The outer portion is flush with the outer surfaces of the flanges.

    摘要: To permit light-weight construction of a rotor of a centrifuge holding sample carriers adapted to retain probes, the rotor is formed at its outer circumference with a sleeve of at least partly fiber-reinforced plastic. The holders are secured to the rotor and movable in guide means so that when swinging outwardly under centrifugal force, they can abut against the outer sleeve, preferably with interposition of a segmental element to provide for large area contact, the fiber-reinforced plastic sleeve, being continuous and circular, absorbing centrifugal forces.

    摘要: A latch is known for a laboratory apparatus, for locking a cover or door on its housing, having a hook 12 in one of the parts to be locked and a lock 1 in the other. The lock has a pivotable locking element 3 with a claw-shaped opening 9 which engages the hook 12 against the pressure of a spring and is releasable from engagement with the hook by an actuating element 7. In order to provide a latch of this kind with means to meet strict safety requirements and ensure secure locking during operation of the apparatus, an additional closing element 4, opening element 5, and securing element 6, which engage one another, are disposed between the locking element 3 and the actuating element 7.

    摘要: The method relates to the co-culturing of two cell cultures in two cell culture chambers such that the cellular products produced by the co-cultured cells are exchanged between the two cell culture chambers. The apparatus for culturing the cells contains two cell culture chambers separated by a microfiltration membrane which is permeable to medium, gases, and cellular products, and is impermeable to cells. A culture medium supply chamber is adjacent to and separated from the first cell culture chamber by a dialysis membrane which is permeable to medium and gases. The exterior portion of the second cell culture contains a gas-exchange membrane which allows gas exchange between the apparatus and the environment. The apparatus can be in a modular form where the first and second cell culture chambers form one module which is detachable from the culture medium supply chamber which forms the second module. The method and apparatus allows the exchange of media, gases, and cellular products between the two cell cultures while preventing direct contact of the two cell cultures.

    摘要: The purpose of the present invention is to attain optimal gas exchange, nutrient supply and disposal of metabolic waste products without contamination during high-density cell cultivation of adherent cells. The culture vessel of the present invention provides methods and apparatus for the cultivation of cells on a three-dimensional carrier in a closed cell culture chamber, the supply with oxygen taking place across a gas-permeable gas exchange membrane bordering the cell culture chamber and the supply with nutrients taking place across a dialysis membrane bordering the cell culture chamber, across which nutrients are transported and across which metabolic products are removed, without the danger of contaminating the cells during contact with the tools necessary for manually separating the cells being cultivated from the nutrient medium. The cell culture chamber of the present invention features a vessel that is impermeable to fluids on all sides except for the boundary formed by the dialysis membrane. This makes it possible to move the cell culture intensively within a fluid nutrient supply medium. It is neither necessary to open the cell culture chamber during cultivation to introduce new nutrients, nor is it necessary for the design to include components which reach into the cell culture chamber, and form an additional source of contamination. The gas exchange membrane is detachable to allow removal of the cultivated cells in a uniform layer on the carrier, and the carrier is bio-degradable to eliminate the need to remove the cells from the carrier prior to use, such as in the transplantation of skin for example.
