Combinational logic circuits are used with a temporary storage device holding data bytes to detect improper bits in both the lower and upper nibbles of the bytes. Combinations of bit patterns derived from both nibbles permit flagging the occurrences of a variety of bit errors existing in sequentially transmitted parallel data bytes.

The invention realtes to a process for producing foams based on polyisocyanates by reacting polyisocyanates, compounds having at least two hydrogen atoms reactive towards isocyanate groups, blowing agents and, if appropriate, further additives. In this process, a blowing agent is used which is composed to the extent of at least 10 mol % of one or more fluoroalkanes of the formula I CaHbFc where a=...

A brake booster includes at least two pairs of constant pressure chambers and variable pressure chambers defined within a shell. A clearance is defined between a stepped end face of a valve body which is disposed within the shell and a power piston which is mounted on the valve body at a location rearward of the stepped end face.

An integral polyether-sulfone membrane with a pore system open at the outer boundaries is in the form of flat films, tubular films or hollow fibers having a maximum pore diameter of 0.02 mu m to 2 mu m. The pore system is cellular throughout with cells having polyhedrally symmetrical boundaries. The cells are arranged asymmetrically from one surface of the membrane to the other, the asymmetry fa...

Mixtures of aromatic and non-aromatic hydrocarbons are separated into aromatic enriched and non-aromatic enriched streams, by passing them over a polyethylene terephtalate membrane.

An expanded polyolefin foam with uniform fine closed cells is produced by placing a pre-form of a heat-expandable polyolefin resin composition in a mold cavity of generally uniform depth and closed by a platen, heating the mold to a temperature above the blow activation temperature of the pre-form while constraining the pre-form against any expansion under heavy controlled pressure, and then after...
