The cutting mechanism for the document shredder is driven via a two-part clutch. In forward motion, the two clutch shells are connected to each other by means of elastic elements which are pressed together to a greater or lesser extent as a function of the load. In both clutch shells are arranged openings which, in non-overloaded forward motion, open the ray path of a light barrier attached on bot...

For preparation for bonding with plastic, a layer is applied to a substrate surface by sand blasting with an agent which consists of (A) 0.01 to 90% by weight of optionally silanised material having a particle size of < 5 mu m and a greater hardness than that of the substrate surface and/or (B) 20 to 100% by weight of silanised, silicon-containing material having a mean particle size of 2 to 200 ...

A depth measurement system produces independent signals, each presumably corresponding to the same movement of a wireline if produced under ideal wireline measurement conditions. The system utilizes the signals to provide an accurate and repeatable signal under varying wireline measurement conditions and is particularly suitable for driving a recorder for depth recording and merging measurements f...

Monoclonal antibodies to IFN- beta 2/IL-6 and hybridomas producing them and production and purification of glycosylated and unglycosylated IFN- beta 2/ IL-6 are disclosed. The protein is useful in the treatment of breast cancer, leukemia, infectious diseases and bone marrow progenitor cell disorders.

This invention deals with viscosity improvers which are obtained through the use of a mixed catalyst system comprising a tertiary organo halide and a Lewis acid catalyst.

A flex-resistant oriented polyester film comprises a blend of a linear polyester, an incompatible resin and an ionomer resin.

PURPOSE:To produce hydrogen stably for a long time and economically by carrying out reforming of kerosene in the presence of a steam reforming catalyst after removing S from the feed kerosene and adding water thereto. CONSTITUTION:Kerosene contg. <=0.2ppm by wt. S is obtd. from a kerosene fraction A having <=150ppm. by wt. S content mixed with gaseous H2 after pressurizing to a reaction pressure w...

When pyrolysis gas obtained in the pyrolytic decomposition of starting material is cooled, process water is formed which, because of its content of chemical compounds, can only be disposed of or eliminated at high cost. The process water is therefore recycled to the pyrolysis reactor (10) operating with a fluidised bed (16). In this way, the process water arising is diminished in a simple manner a...

PURPOSE:To selectively and effectively remove extremely small quantities of mercury in oil and facilitate separation of catalytic substance after the reaction, by bringing a hydrocarbon base oil containing mercury into contact with an adsorbent having copper on a carrier such as activated clay. CONSTITUTION:An adsorbent consisting of (A) one or more carrier selected from activated clay, silica gel...
