Title: Improvements in or relating to the preparation of cyano-cobalamine
IPC: C07H23/00
Filed: 1956-12-14
Abstract: Cyano-cobalamine is prepared from a liquid suspension or solution containing at least one substance of the cobalamine group, in a process wherein the starting material is first treated with sulphite ions, followed by increasing the content of the vitamins of the B12 group to at least 200 times that in the starting material, in volumetric terms, by means of extraction, adsorption and elution processes followed by evaporation under reduced pressure, and the concentrated solution treated with cyanide ions, the cyano-cobalamine produced being finally isolated in crystalline form.  The suspension or solution containing a substance of the cobalamine group may be a fermentation liquor prepared for the purpose of producing Vitamin B12, a sludge or residue from methane fermentation, an activated sludge or a liquid fish preparation.  The fermentation sludge is heated in aqueous suspension in the presence of sulphite ions and the B12 active substances adsorbed in montmorillonite. Subsequent adsorption on charcoal, extraction and evaporation are also effected in the presence of sulphito ions.  When the sulphito-cobalamine content reaches 1 g/Kg in relation to dry substance conversion of cyano-cobalamine may be effected.  All subsequent steps are then carried out in the presence of cyanide ions.  This may take place in cellulose columns, butanol being used for the separation in the presence of cyanide ions.  Examples describe the preparation of Vitamin B12 extracts from fermentation sludges and from bacterial cultures.  Specifications 681,503, 693,125, 727,146, 745,504, 748,043, 765,537 and 767,630 are referred to.

Title: A device for deriving an electrical signal representing the shaft position of the mill screw of a metal rolling mill
IPC: B21B38/10
Filed: 1964-09-21
Abstract: 1,078,865. Electrical control systems. CANADIAN GENERAL ELECTRIC CO. Ltd. Sept. 21, 1964 [Sept.21, 1963], No. 38476/64. Heading G1N. In an automatic control system, Fig. 5, for the rolls of a metal rolling mill, each roll-driving screw positions the sliders of three rotary potentiometers 25, 28, 29, the sliders of which are fixed 120‹ apart relative to their end sectors (the arcs containing the terminals of the potentiometer), and that potentiometer whose wiper is furthest from its end sector at the beginning of each pass is switched into the control circuit for the duration of the pass by operation of a micro-switch 30, 31 or 32 which actuates a corresponding relay 43... 45. The desired roll position is set in via a reference potentiometer 70 which, like potentiometers 25, 28, 29, is connected, in series with a trimmer rheostat, across an A. C. supply. The outputs of the measuring potentiometer 25, 28 or 29 and reference potentiometer 70 are compared In a transformer 46, the error signal therefrom being amplified and fed to a servomotor to rotate the driving screw, and the sliders of potentiometers 25, 28, 29, to the null position. Circuitry 76 between micro-switches 30... 32 and relays 43... 45 includes a "hold" circuit for the operated relay, and an interlock circuit to prevent energization of other relays. Two, or more than three, measuring potentiometers may be employed, their sliders being successively displaced by 360‹/n. Transducer construction. Fig. 2. A shaft 8, journalled in bearings 10, 11, is coupled to the drive-screw of the mill for angular movement therewith. A gear 15, mounted towards the base of shaft 8, meshes with three equally-spaced gears - two only, 22, 23 are shown - to drive the three measuring potentiometers such as 25, 29 via three stub shafts such as 17, 18. At the upper end of shaft 8 a cam 16 operates in succession three equally-spaced micro-switches such as 31, 32. The actuating surface of the cam extends over more than 120‹, so that overlap occurs in the operation of the micro-switches.

Title: Device for indicating the free water content in hydrous crystalline substances
IPC: G01N33/02
Filed: 1977-09-15
Abstract: A sensor (13) having two electrodes forms a galvanic cell whose electrolyte is produced as a result of the granulated sugar to be monitored being dissolved by the atmospheric humidity. After passing through the interference suppression device (14, 15), the output voltage of the sensor (13) is fed to the buffer amplifier (5). The Schmitt trigger (7) converts the analog signal arriving from the buffer amplifier output into a digital signal which is necessary to actuate the switch (16) and zero the counter (9). If there is a signal exceeding the fixed threshold value at the input of the Schmitt trigger (7), the switch (16) is in the switched-on position with the result that the pulses from the timing generator (8) reach the input of the counter (9). The comparator (11) serves to compare the output signal of the counter (9) with the preselected time-segment signal stored in the programming unit (10). If the two items of data at the inputs of the comparator agree, the signalling device (12) is actuated. <IMAGE>

As shown, Fig. 1, a scanning unit 4 comprises a TV camera viewing an area of the preparation through a microscope and operates under control of a unit 5. The scanning unit 4 incorporates a signal shaper and a level slicer capable of providing an output signal when the video signal lies in a band between selected pairs of sixteen density levels. Six of these bands are selected in turn by signals from the control unit 5. The output of the scanning unit is applied to an AND gate together with clockpulses so that the number of pulses produced is proportional to the area of a cell within the selected density band. This area is weighted according to the density level selected  this being achieved by means of a variable divider unit 6 the division ratio of which is controlled by a counter (25) which is incremented by a pulse from from the control unit at each change of density band. The weighted output count is accumulated in a reversible counter 7, the counting direction being reversed at each change in density band, this producing in effect weighting coefficients of alternate signs. Before the measurement begins the reversible counter is set to a given value which corresponds to the subtraction of a constant from the total. The weighting factors are selected so that when all six density bands have been analyzed the counter holds a value which is positive for normal cells and negative for atypical cells. Two counters 26, 27 accumulate the number of atypical cells and the total numbers of cells examined respectively and when a total of 100 cells have been analyzed to output of counter 26 is decoded by logic circuit 3 to provide an output on line B, C or D depending on whether the preparation is normal, doubtful or pathological as represented by the number of atypical cells being below, between or above two threshold values. If the number of atypical cells exceeds the upper threshold value before 100 cells have been analyzed the preparation is classified as pathological and the measurement terminated.
