IPC: G11B15/34
Abstract: 1,053,723. Feeding magnetic tapes stepwise. SCM CORPORATION. March 18, 1963 [April 3, 1962], No. 29953/65. Divided out of 1,053,721. Heading G5R. The description of the magnetic tape recorder forming the matter of the present invention is included in the parent Specification 1,053,721, and relates to a recorder and playback apparatus including means for moving the tape in steps past the recorder-reader head, and comprising means to provide a direct driven tape feed movement on the infeed side of the head and means operable subsequent to said tape feed movement for accomplishing a constant rate stepping movement of said tape past the head under power derived from the preceding tape feed movement. Tape feed.-The tape 540 is passed stepwise over the record/read head 542, and over sprocket feed wheel 543 and stepping sprocket 549 to spool 566 which is driven by a slipping clutch. Spring-biased stabilizer roller 544 takes up any feed slack. When the circuitry energizes feed solenoid 246 a ratchet and pawl mechanism moves feed wheel 543 one increment and is followed by a tape-stepping action by wheel 549 which is driven by an escapement controlled lost motion mechanism, see Figs. 38, 43, 44 (all not shown). Tape position indicator.-Wheel 631 is driven via gearing by the feed ratchet and pawl assembly and has four annular metal contacts affixed to it. One of these is connected to earth and the others via indicator lamps to a potential by plunger contacts 648. The annular contacts have lengths such that the lamps glow at the start of the tape, at the end of the tape and when 96% of the tape has been used. Rewind.-Stepping of the tape takes place against the action of spring 626. When rewind solenoid 254 is actuated the feed ratchet and pawl is released and pressure from the stabilizer roller 544 is eased. Spring 626 now drives, through gearing, sprockets 543, 549 to rewind the tape on to frictionally driven supply spool 541. Rewind is stopped by a mechanical stop. General details of recording.-The tape carries two tracks, one for telegraph code signals derived from a local keyboard and the other for timing pulses used for clocking the signals and for controlling functions of the station. The control circuitry causes the tape to step a few times before rewinding and before recording to ensure that there is a blank section on the tape between any two messages. When reading the record one complete message is read, the recorder then automatically stopping. The blank section indicates the end of message.

Abstract: 1,227,023. Treating bauxite. PECHINEY COMPAGNIE DE PRODUITS CHIMIQUES ET ELECTROMETALLURGIQUES, and SOC. APPAREILS ET EVAPORATEURS KESTNER. 19 March, 1968 [20 March, 1967], No. 13181/68. Heading C1A. Bauxite is treated (to achieve a dissolution of the alumina content of the bauxite) with an aqueous solution of caustic soda and sodium aluminate in suspension in a series of pressure stages of increasing temperature, the final pressure stage being heated by live steam. The suspension is then passed through a series of expansion stages in which the suspension is cooled by partial vaporization. The first and each intermediate pressure stage comprises a mixing exchanger 44 and reservoir 45, suspension passing from the preceding stage into mixing exchanger 44 where it is heated to near its boiling point by direct injection of steam from a corresponding expansion stage 41. The reheated suspension remains in reservoir 45 until the solubility equilibria are reached, when an amount of suspension equal to that received from the preceding stage is passed via 46 to the next pressure stage, the excess being pumped via 47 to evaporator 42 wherein it is partially vaporized by the steam from 41, the remaining unvaporized suspension returning to the reservoir by gravity. In a modification of the process only the aqueous solution of NaOH and NaAlO 2  is passed through the initial pressure stage or stages and the bauxite is added in a later stage.
