Abstract: Abstract of the Disclosure A method for preswelling and drying, hydrophilic regenarated cellulose membranes involving solvent exchange with a hydrogen bond breaking hygroscopic polar solvent followed by drying.  The resulting, membrane can be directly used without further treatment for polar organic liquid permeation such as polar dewaxing solvents from dewaxed oil.  Preferred hygroscopic polar solvents are sulpholane, dimethyl-sulphoxide (DMSO), dimethylformamide (DMF), n-methyl pyrrolidone (NMP), other disubstituted sulphoxides, disubstituted sulphones, other disubstituted formamides and dimethylamine (DMA) and morpholine.  Most preferred solvent is DMSO.          The method of the present invention is useful not only for pretreating fresh membrane material but also for recovering the permeability of damaged membranes (i.e. dried, water damaged or pressure damaged membranes).

Abstract: ABSTRACT      This invention discloses an amorphous silicon semi-conductor film comprising at least hydrogen, nitrogen and oxygen as impurities and the method to produce it.  The film is characterized in that the total quantity of nitrogen and oxygen in said film is at least  1  atom %.  Since the film has small light absorption coefficient and its optical refractive index is controllable, an excellent window material for solar ceil can be provided.  As an adherence of the film with metal electrode as well as with transparent electrode is sufficient, the good reproducibility in making solar cell using the film of this invention as window material was realized.

Abstract: Sphingosine Derivatives, Their Preparation and Pharmaceutical Formulation Abstract of the Disclosure New compounds of the formula (I)-D and (I)-L as shown in the sheet of formulae are described, for example D- and L-erythro-1-(.delta.-D-glucopyranosyloxy)-3-hydroxy-2-palmitoylamino-4-trans-octadecene, which exert actions promoting wound healing and cell and tissue regeneration, and can be used therapeutically for the treatment of wounds of any cause.  They are prepared in good yield and in a stereochemically homogeneous form from ceramides of the formula (II)-D and/or (II)-L.  The process comprises the protection of the 1-hydroxyl group, esterification of the 3-hydroxyl group, elimination of the 1-hydroxyl pro-tective group, reaction with the trifluoroacetimidate or trichloroacetimidate of a 2,3,4,6-tetraacylated D-glucose and elimination of the O-acyl groups.  When a D,L-ceramide (II) is used, the esterification of the 3-hydroxyl group is carried out by an optically active acid followed by separation into the diastereomers, or separ-ation into the diastereomers is carried out after the reaction with the D-glucose derivative.

Abstract: ABSTRACT     A double pump adapted for use as an artificial heart includes two ventricle-simulating chambers that are provided with respective inlets and outlets having valves incorporated therein and that are separated by a common par-titioning wall structure. The wall structure has sections that are driven away from each other to reduce the volumes of respective ventricle chambers and expel liquid from the chambers through the outlets. The wall structure can also move laterally in response to differences in pressure between the chambers and hence change the volumetric ratio between them. This ensures a balanced action between the two halves of the heart-simulating pump during a systole phase and a diastole phase. The link mechanism is actuated by a cord through a motor, although only in one direction in the pres-sure phase, and hence the aforementioned changed volumes are readjusted primarily through the pressure exerted by the inflowing fluid. The pump may also include a variable volume atrium-simulating chamber communicating with the inlet to each ventricle-simulating chamber and having volume that is controlled in part by an externally acting gas pressure that varies in accordance with changes in the volumes of the ven-tricle chambers.

Abstract: ABSTRACT OF THE DISCLOSURE Tobacco trimmed from a filler rod is recycled and used in the control of the rod-forming operation.   A reservoir  vessel  is  divided  into  physically-separate chambers, a narrow one of which receives the recycled trimmed tobacco and a wider one of which receives cut tobacco.   Tobacco  is  simultaneously  fed  from  both chambers by a common feeding device to form a metered flow from which the filler rod is ultimately formed. The level of tobacco in the narrow chamber is sensed and the operation of the common feeding device is controlled in response to sensed  levels outside a predetermined range.   If  the  sensed  level  is  too  high,  then  the tobacco is being fed too fast to the rod formation and the common feeding device then is slowed down, thereby slowing the  tobacco feed rate,  while,  if the  sensed level is too low,  then the tobacco is being fed too slowly  to  the  rod  formation  and  the  common  feeding device  then  is  speeded  up,  thereby  speeding up  the tobacco feed rate.

Abstract: ABSTRACT              Selective Permeation Gas-Separation Process and Apparatus A permeant gas is selectively transferred from a fluid-gas mixture which comprises the permeant gas and at least one other component to an output fluid by the process of the invention.  The process involves introducing a selective-permeation liquid into a permeation-transfer chamber.  A gas-depletion channel and a gas-enrichment channel pass through the permeation chamber and are separated from the chamber respectively by porous walls.  The selective-permeation liquid contacts the porous walls but does not flow into the gas-depletion or gas-enrichment channels.  The feed-gas mixture is introduced into the gas-depletion channel so that permeant gas in the mixture can pass through the pores of the walls of the channel into the selective-permeation liquid and from the selective-permeation liquid through the pores of the walls of the gas-enrichment channel in the gas-enrichment channel.  Permeant gas is withdrawn from the gas-enrichment channel and a stream of gas depleted in the permeant gas is withdrawn from the gas-depletion channel.  A gas-transfer unit permits the process of the invention to be carried out effectively.
