Title: Manufacture of condensed phosphates
Inventor: KOEBNER ADOLF
IPC: C01B25/39
Filed: 1961-04-25
Abstract: <PICT:0970727/C1/1> Alkali metal condensed phosphates are prepared by calcining an alkali metal orthophosphate, or mixture thereof, in a fluidized bed in which there is initially present already condensed phosphates in an amount of at least 50% based on the total weight of the material constituting the fluidized bed which amount is also maintained in and as part of the bed throughout the process. Calcination, which may be effected at between 440 DEG  and 450 DEG C., may be carried out continuously, fresh orthophosphate being introduced into the fluidized bed at the same rate as condensed phosphates are removed therefrom.  A number of reactors connected in series may be used, wherein a proportion of the condensed phosphates produced is recycled from the last reactor to the first. The alkali metal orthophosphate, or mixture thereof, may be supplied to the bed in the form of a solution or solid or a mixture of solution and solid.  As shown in the diagram, a typical reactor 10 comprises beds 14, 15, 16 fluidized by air and combustion products which enter from pipes 17, 18 via furnaces 23, 24, and by air entering from pipes 19, 20.  Entrained dust is trapped in cyclone 28 and returned via pipe 30 to bed 15. Orthophosphate is charged through pipe 31 and is preheated in bed 14 before discharge to bed 15, which has baffle plates 33, 34, to secure adequate retention time for conversion to condensed phosphates. The product passes to bed 16, where heat exchange is effected with the air entry, before discharge through pipe 37. In a typical example, equal amounts of sodium orthophosphate flake and sodium triphosphate were mixed and sieved to a particle size between No. 30 B.S.S. and No. 10 B.S.S. sieves.  Conversion to condensed phosphates was effected at 445 DEG  C. by fluidization with hot air for 2 1/2 hours.

Abstract: 333,575. Clark, G. M., (Krueger, T. H.). May 13, 1929. Coating webs. - Apparatus for moistening and delivering adhesive tape is provided with means for causing the tape to assume or retain a channelled crosssection with the adhesive inwards so that there may be presented to the operator a length of moistened tape having flanges at its sides whereby it may be gripped by the fingers without touching the moistened gum. A roll 14 of tape 15 with its adhesive side outwards is centered in a cradle 13 by guides 16 provided with a right and lefthand screw 17. Serrated discs 27, Fig. 5, cooperate with bevelled flanges on rollers 28 to draw the tape over the flat end of a guide plate 32 which becomes channelled in section to correspond with the folding of the tape by the roller 28 and discs 27. The discs 27 are mounted on a shaft 26 adapted to be rotated by a pinion 22 driven through ratchet and pawl mechanism by a spring-pressed handle 20 disposed outside the side plates 11 of the machine. A saddle 33 holds the strip on the plate 32 prior to its passage past a cutting device comprising a blade 38 guided between fixed plates 39 and formed with cutting edges disposed at an angle to the parts of strip they are intended to cut, the cutting being thus effected by a drawing motion. The blade 38 depends from an arm pivoted at one end and provided at its other end with a link which connects it to a slotted latch adapted to be rocked idly on the downward movement of the operating handle but to draw down the blade and server the strip on the return movement thereof. The projecting portion of the strip is retained by a saddle 53 while it is engaged by a brush 54 in a moistening bath 55. The transformation of the strip to channel formation may be effected between the cutting and the moistening device or at or after the moistening device. The tape produced is creased longitudinally along two parallel lines separated by a distance of at least one eighth of the width of the strip or by not less than a quarter of an inch, if this is greater, and not more than seven eighths of the strip or three and a half inches, whichever is less.

Title: Automatic cuing and control system for optical printers and the like
IPC: G03B27/73
Filed: 1969-03-24
Abstract: 1,224,304. Programmed printing control. METRO GOLDWYN MAYER Inc. March 24, 1969 [April 12, 1968], No. 15262/69. Heading G3N. In an automatic cuing and control system for printing from a master film a unique address is assigned to each film frame which is monitored and compared with a stored cuing address and control information for an optical printer released accordingly. As shown, a bi-directional tapereader 50, has a drive roller 51, advancing a tape 53, which is driven by a tape drive 55 through a clutch 56 operated by a reader drive logic 58. The tape bears six rows of perforations with at least eight binary bits in each row and is read a row at a time. The reader 50 passes the binary data to selector gates 66 which, controlled by gate drive logic 64, selectively route the data into a cuing frame address register 68, fade memory 72 or colour memory 70. The routing sequence is determined by a forward/reverse selector 60 for the tape drive 55 and a master film drive 62. The frames of the master film are monitored by a transducer and counted up or down, with reference to a zero sync frame, by a binary counter 74. The contents of the counter 74 are compared in a digital comparator 76 with the count set into the cuing frame address register. At co-incidence a pulse is generated from the comparator which, through a buffer amplifier 78, triggers printer control operations represented by the last row sequence read from the tape. The fader 86 of an optical printer, not shown, is actuated from the memory 72 through an operational amplifier 84 and a light change system 82 is operated from the memory 70 through an operational amplifier 80. The pulse is also fed to the reader drive logic 58 to initiate movement of the tape and the sequential read-out of the data relating to the next printing sequence.
