Foam sheets of high compressive strength are produced by extrusion of a mixture of a styrene polymer and 5 to 16% by weight of a blowing agent mixture which contains a) from 3 to 70% by weight of an alcohol or ketone having a boiling point of between 56 and 100 DEG C b) from 0 to 50% by weight of carbon dioxide, c) from 0 to 88% by weight of a saturated C3- to C5-hydrocarbon, and d) from 2 t...

A method for analyzing in real time the performance of an electrically controlled mechanical device 10 is provided. Control parameters which are important to know on a microprocessor clock-cycle-by-clock-cycle basis are monitored so that the various components 14 of the system can be synchronized with each other if needed, and their performance analyzed. Control parameters are also monitored over ...

A high frequency surge tester includes a high frequency detection circuit which is used to detect microfracture defects in the insulation of wire on wound coils. The high frequency detection circuit includes a high-pass filter which isolates an errant voltage response so that it can be integrated and compared to threshold limits to determine tine magnitude of defects. The surge tester also detects...

A continuous stirred-tank reactor suitable for the liquid-phase oxidation of an aromatic alkyl to an aromatic carboxylic acid is provided with vertically disposed, relatively narrow baffles on the reactor wall and with oxidizing gas inlet means below the agitator in the reactor. The baffle width is about 0.02 to about 0.04 times the diameter of the reactor.

The specification describes and claims a moisture curable composition comprising hydroxypolysiloxane, silane curing agent finely divided filler (preferably calcium carbonate), catalyst, and as rheological additive, a polymer having on its polymer chain at least one carboxylic acid anhydride group. Preferred rheological additives are polybutadiene polymers treated with e.g. maleic acid anhydride. T...
