Thermoplastic polystyrene laminates are disclosed, one of the layers of which comprises a filled polystyrene composition containing from about 5 to about 50 of filler, such as calcium carbonate, clay, asbestos, etc. The filled polystyrene composition is prepared from a filled polystyrene masterbatch of impact polystyrene, filler, rubber and mineral oil, cut back by mixing with other polystyrene, e...

Porous cellulose beads are prepared by distributing droplets of a solvent mixture containing a cellulose derivative into a precipitating solution to form porous beads which are then washed and hydrolyzed to form porous cellulose beads. The porous cellulose beads, which may be cross-linked, if desired, by suitable treatment, are useful carriers to which enzymes can be immobilized. The beads may a...

A process for producing a binder (cement) to be used in slurry, mortar, or concrete having a low water-to-cement ratio. As raw-material for the binder is used at least 50% by weight of a hydraulic material, such as slag, technical pozzolanas and/or natural pozzolanas. The hydraulic material is ground to a specific surface of at least 400 m2/kg. To the raw-material is added 0.1 to 5% by weight of a...

The invention relates to a sound-damping element (1), in the outer layers (3, 5) of which U-profiles (6-11) are inserted. The U-profiles (6-11), preferably made of steel, increase the sound-damping value of the element from 39 dB to 44 dB. Gluing the U-profiles (6-11) into the outer layers (3, 5) of the element moreover ensures better rigidity of the element (1).

The radially outer wall (22) of the annular groove (10) extends like a truncated cone and is enlarged towards the open end (13). The annular groove (10) is confined by ...

A resiliently flexible strip device mounts the armature of an electrically released brake for movement toward and away from the pole faces of the field shell, the armature either moving with pivotal motion or with linear motion. The resiliently flexible strip device may take the form of one or more leaf springs or may be one or more tongues molded integrally with the flange of a bobbin which forms...

There is disclosed the use of solid blowing agents to generate polyimide foams which have low densities and identation load deflection (ILD) values and a relatively open cellular structure with larger cell sizes. The preferred method includes the steps of: preparing, foaming, and curing a precursor containing at least one alkyl ester of 3,3 min ,4,4 min -benzophenonetetracarboxylic acid; at l...

Inertial measurement of the angular rotation and translational motion of a structure can be provided by a pair of vibrating accelerometers 10, 12 aligned in a side-by-side arrangement with their force sensing axes A<1>z, A<2>z in the same plane and vibrated to and away from each other in that plane along an axis normal to their force sensing axes.

PURPOSE:To memorize digital data, by comparing the saw tooth wave voltage with the comparison voltage and setting the counter output at the time point when they are in agreement to the memory unit.

The housing parts (6; 12, 13), which contain the end (9) of the supply lead and the terminal parts of the jacks (8) in subdivided accommodating chambers (7), are configured in the manner of half-shells (12, 13). The latter are mutually anchored by means of a hook-in connection (22, 24; 23, 25) which is active in the region of the entry fitting. A front part (1) of the connector containing the cont...
