Abstract: A multi-channel transparent jacket for accommodating strips of microfilm to create a microfiche, the jacket having non-blocking characteristics, thereby minimizing the tendency of one jacket in a stack thereof to stick to an adjacent jacket. The jacket is constituted by front and rear panels formed of flexible polyethylene terephthalate film joined together by a parallel array of ribs to define the channels. The exposed surfaces of the panels have a friction-reducing layer thereon constituted by a multiplicity of discrete silicon dioxide nodules bonded to the film, the nodule shape approximating a surface segment of a sphere. The peaks of the segments form microscopic contact points which are bonded by molecular attraction to an abutting panel when the jacket is juxtaposed against a like jacket in frictional relationship thereto.

Abstract: A multi-channel transparent jacket having top and bottom panels joined by ribs to define parallel channels loadable with microfilm strips to create a reproducible microfiche master, the jacket having entry slots adjacent the front end of the channels to facilitate insertion of the strips. The lowermost channel is pre-loaded with a removable dummy strip to stiffen or somewhat thicken this channel and thereby prevent a partially-loaded jacket from buckling or sliding under when a stack of jackets is stored in a file drawer. The ends of the dummy strip are notched to facilitate the later loading of the lowermost channel through the channel entry slot with a film strip which displaces the dummy strip.

Abstract: New salts of 5'-methylthio-5'-deoxyadenosine (MTA) with long-alkyl chain sulphonic acids, which possess central and peripheral vaso-dilatory, platelet antiaggregation, antiinflammatory, analgesic and antipyretic activity.Said salts are produced by dissolving the sodium salt of the chosen sulphonic acid in distilled water, dissolving the MTA in distilled water to which H.sub.2 SO.sub.4 has been added, reacting together the two solutions to precipitate the MTA sulphonate, and recovering this latter salt with a high degree of purity.

Abstract: A random-access card file system formed by card-storing cartridges, each capable of accommodating at least one deck of cards, and an automatic card selector adapted to extract any desired card therefrom regardless of its location in the cartridge. Each card in the deck includes an upstanding tab whose longitudinal position is related to a particular point on an incremental linear scale extending the full length of the deck. The selector includes a carriage movable to a position in registration with any desired incremental point on the scale, the carriage supporting a crane having a card picker thereon, whereby when the carriage is set to a particular scale point and a switch is actuated, the crane completes an operating cycle in the course of which it bows down over the cartridge to enable the picker to engage and clamp onto the tab of the selected card and to then lift the card to withdraw it from the cartridge.

Abstract: A multi-channel transparent jacket to accommodate microfilm strips having a given thickness. The jacket is constituted by top and bottom rectangular panels of flexible synthetic plastic material and plastic ribs formed in situ along parallel lines between the panels and integrally bonded thereto to maintain the panels in spaced relation and to define open-ended channels whose width is substantially equal to the width of the strips. The thickness of the ribs is substantially equal to that of the strips whereby the strips are snugly held within the channels.

Abstract: A method for producing a multi-channel transparent jacket to accommodate microfilm strips having a given thickness, the jacket being constituted by top and bottom rectangular panels of flexible synthetic plastic material and plastic ribs formed in situ along parellel lines between the panels and integrally bonded thereto to maintain the panels in spaced relation and to define open-ended channels whose width is substantially equal to the width of the strips. In the method, extruded molten streams of polyester material compatible with the material of the panels are directed onto the surface of a first web of panel material in parallel paths thereon, the first web being advanced concurrently with a second web of panel material into combining rolls which act to compress and flatten the streams to produce the in situ ribs, the combined web then being sectioned into individual jackets.
