Abstract: A plate evaporator or condenser has a plurality of plates forming a plate stack and defining alternating chambers for a first fluid to be evaporated and a second fluid to be condensed. Each plate has embossed thereon a plurality of parallel spaced beads projecting into the chambers for the first fluid and are oriented parallel to the plate length. Mutually aligned beads of adjoining plates are in contact with one another. Each plate also has, embossed thereon, a plurality of spaced knubs situated between the beads and projecting into the chambers for the second fluid. Mutually aligned knubs of adjoining plates are in contact with one another. The plates further have first and second apertures provided in opposite end zones and extend substantially throughout the plate width. Mutually aligned respective first and second apertures of adjoining plates form first and second flow channels for the first fluid. The first and second flow channels are in communication with the chambers for the first fluid. Each plate has, in the end zones between the first and second apertures, first and second lateral enlargements projecting beyond the rectangular plate outline. Third and fourth apertures are provided, respectively, in the first and second lateral enlargements. Mutually aligned respective third and fourth apertures of adjoining plates form third and fourth flow channels for the second fluid.

Abstract: O-acetylated glycals react with ceric ammonium nitrate in the presence of sodium azide to provide, in good yield, O-acetylated 2-azido-2-deoxy glycosyl nitrates. These nitrates can be used to prepare 2-amino-2-deoxy sugars, such as D-galactosamine and lactosamine. The O-acetylated 2-azido-2-deoxy glycosyl nitrates can alternately be converted to O-acetylated 2-azido-2-deoxy glycosyl halides which are useful in the preparation of O-acetylated 2-azido-2-deoxy glycosides, which in turn can be reduced to 2-amino-2-deoxy glycosides. Of particular interest are the syntheses of 2-amino-2-deoxy glycosides which correspond to the terminal units of the antigenic determinant for the human A blood group. Attachment of these glycosides to a solid support provides immunoabsorbents which efficiently and preferentially absorb anti-A antibodies from blood plasma.

Abstract: A process for the formation of high purity alumina from Bayer Process alumina trihydrate (gibbsite). The solid hydrated alumina is reacted with concentrated HCl to cause partial or complete conversion to aluminum chloride hexahydrate (ACH). The ACH or mixture of ACH and unreacted hydrated alumina is recovered as a solid and calcined in a single or multistage calcination to high purity alumina. Soda contents in the product anhydrous alumina can be reduced by 98% or greater. Contents of other impurities, such as silica, iron, magnesium, etc., are also markedly reduced. Different degrees of impurity reduction can be obtained by controlling the degree of conversion of the hydrated alumina to ACH and by recycling and treating the acid after solid/liquid separation. The purified products find use in the speciality ceramics field, as catalyst supports, as adsorbents, in electronic components, in prosthetic devices or other applications in which alumina of controlled degrees of purity offers an advantage.

Abstract: The fibrous material (20) is transported in fluid by a choke type rotary sluice (3) with fluid-filled through pockets (27,28). The sluice has an upper inlet chamber (2) with a transport fluid level (24) maintained by fluid circulating through the pockets, and simultaneously transporting the fed-in fibrous material. The material comes up against a sieve (35) at the bottom of the pockets and fills the pocket volume, so that part of the pocket fluid content is displaced corresp. to the volume of the fibre material. The displaced fluid volume is calculated and used to determine and regulate the volume of material which per time unit is transported to the treatment stage. In the calculation of the fluid volume, adjustment is made for possible additional or reduced fluid amounts, likewise for possible fluid leakage in the sluice, absorption of fluid by the material, and for condensed vapour.
