Abstract: Enzymes are immobilized, stabilized and evenly dispersed without destroying their activity by sequestering them within micropores of a solid carrier structure and filling the pores with a water-immiscible organic liquid, in which the enzyme remains active. The preferred solid carrier is a microporous membrane. The system is manufactured by providing a solid carrier having a microporous surface whose pores contain an aqueous solution, allowing an aqueous solution of enzyme to equilibrate with the solution in the pores, causing a controlled partial collpase of the pores to effectively trap the enzymes, and replacing the liquid in the pores with a water-immiscible organic liquid. The system can be used to assay for or produce an organic compound. It also can be used for slow release of an enzyme.

Abstract: A holographic optical correlator includes a matched optical filter and control means therefor including a memory. In use searching for occurrences of an item to be found is carried out by the control means controlling the input and Fourier transform planes of the filter and a coherent light source for parallel optical processing of the memory content and the output plane of the filter provides information to the control means as to the location in the memory of occurrences of said item. The complexity of the detector means in the output plane can be reduced in comparison with previous proposals by moving the item to be sought step-wise across the input plane. The detector means then may comprise a single column of detectors which are required to detect a peak correlation signal within a predetermined range.

Abstract: A stream of compressed air has water and carbon dioxide removed therefrom in a purification apparatus 4 and is then cooled in heat exchanger 6 to a temperature suitable for its separation by rectification. 
     The rectification is performed in a dephlegmator 8 that takes the form of a plate fin heat exchanger having four distinct sets of passages 10a, 10b, 10c and 10d. The rectification of the air takes place in passages 10a, and oxygen-enriched liquid passes from the bottom thereof upwardly through the passages 10b in which it is sub-cooled. The sub-cooled liquid oxygen is passed through expansion valve 30 and then flows downwardly through the passages 10c providing the necessary cooling to condense gas in the passages 10a and thus provide a reflux flow for the rectification of the air. The oxygen-rich fluid passing out of the passages 10c flows back through the heat exchanger 6 and is taken as product. Nitrogen is taken from the top of the passages 10a and is passed downwardly through the passages 10d and is thereby superheated. The superheated nitrogen is warmed in the heat exchanger 6, withdrawn at intermediate temperature therefrom, expanded in turbine 44 to meet the refrigeration requirements of the process and then passed through the heat exchanger 6 from its cold to its warm end.
