Abstract: A rotating drum adsorber process and system includes a rotating drum of adsorbent medium in a shell including partitions which define an adsorption sector, a regeneration sector and a cooling sector, and which continuously rotates through the sectors. The process and system includes an arrangement for sensing the temperature difference between the temperature of the discharge exiting the leading edge of the regeneration sector and the regeneration sector average discharge temperature for automatically controlling various operating conditions of the rotating drum adsorber system. A computerized method for accurately predicting the contamination level of the gas stream exiting the adsorption sector and optimizing the performance and fractionation efficiency of the rotating drum adsorber system is also included.

Abstract: A cassette which includes top, bottom and side panels. The top, bottom, and side panels are made of a bendable material such as paperboard. Such cassettes may be produced at low cost and are especially useful in the mass mailing of promotional advertising.

Abstract: A semiconductor device subassembly of an elongated conductive lead member, a refractory metal slug and a brazing disk is constructed by mechanically securing the slug to the lead member, assembling the brazing disc to contact both the slug and the lead member and thereafter brazing the slug and the lead member together.

Abstract: A signal defect compensator is provided which develops a replacement video signal for use during a signal dropout. The compensator includes a dropout pulse detector for the generation of a stretched dropout control pulse interval proportional to the duration of the signal dropout.
