Title: Improvements in or relating to the treatment of liquids with lime
IPC: C02F1/68
Filed: 1963-03-27
Abstract: <PICT:0993334/C1/1> <PICT:0993334/C1/2> In an arrangement for treating water with lime to obtain water of a predetermined quality, the conductances of the treated and untreated water is continuously measured and the lime feed is controlled in such a manner that any deviation of the measurements from a predetermined ratio is corrected.  The conductivity cells 81, 82, Fig. 3, switch pump 63 to feed lime from hopper 60 to the upper compartment 26 of tank 10, Fig. 1, in accordance with the ratio of the measurements applied to the controller 80, the lime supply is terminated when the ratio exceeds 1, the minimum ratio prevailing at the point at which calcium bicarbonate and any magnesium salts present have been precipitated and increasing towards 1 as more lime is added.  The lime is fed as a paste 50 lb. to 7 1/2 gallons, of water, which is mixed by depositing the lime on the surface of the water.  Excess lime in the treated water can be removed by recarbonation with flue gas or liquid carbon dioxide to a selected pH value, or by adding a further known quantity of water. Rain water and lime paste are fed into the top compartment 26 through inlet 49 together with a slurry of previously precipitated calcium carbonate from outlet 54 in the lower compartment 27 and rain water is also injected through inlet 47 near a rotor 42 which is coupled to a shaft 40 driven by a motor 36.  The effluent from the upper compartment flows through a conduit 30 wherein further rain water is added by pipe 51 to reduce the excess of lime, and passes through holes 22 in a partition 20, a stirrer 44 maintaining previously precipitated calcium carbonate in suspension, and a rotor 43 stirring a coagulant admitted through a pipe 68.  The coagulated water is passed through apertures 22 to a clarification chamber 12, clarification being enhanced by the downward deflection of the water by a baffle 70.  The treated water is taken off by a conduit 73 in a launder 71. Reference is made to differences of pH in various zones. An alternative arrangement in which the reactor is centrally arranged in the clarifier is described with reference to Fig. 4, not shown. Quantitative examples of water impurities and added lime together with conductance readings are given.  A sparger ring 100 is provided beneath rotor 43 for the injection of flue gas or liquid carbon dioxide.

Abstract: 514,002. Sterilizing liquids. AHLBORN, AKT.-GES., E., and SCHULZ, M. April 25, 1938, No. 12320. [Class 49] Apparatus for heating liquids for sterilizing &c., wherein the liquid passes through an inflow vessel into a heater in which it is stirred and through which it rises continuously, is characterized by the outflow branch of the heater being provided with a throttling device for controlling the rate of flow of the liquid through the heater, so that the interior of the heater is maintained entirely full of liquid, and air is prevented from passing therethrough. The cover of the heater is provided with an opening through which a portion of the rising liquid may overflow and be returned to the inflow vessel, where it is mixed with liquid still to be treated. As shown, milk passes through a pipe 9 to the bottom 8 of a steamheated vessel 1 within which is a rotating drum 3. The milk passes up through the narrow space 5 between the vessel and the drum, stirring vanes 6, 11 being attached to the drum 3 above and below this space. The milk is discharged by centrifugal action through a valve 12 and a pipe 7. The operation of valve 12 is controlled by the variations in level of the milk in a vessel 15 connected to pipe 9, a float 14 in the vessel operating through a rod 13 a bell-crank lever 30, 31 pivoted on a support 29 attached to the valve casing, and valve spindle 20, a valve cone 19, Fig. 2, which co-operates with a seating 17 in the valve 12. The cone 19 is pressed on to its seating 17 by a spring 24 the tension of which can be varied by displacing a screwed bush 25 by means of an adjustable ring 26 or by sliding a weight 38 on lever-arm 31. The rod 13 is adjustable in length. The cover 2 of the vessel 1 has a chimney 32 through which the gases liberated from the milk escape and up which also a portion of the milk overflows into a trough 34 from which it passes through a pipe 33, or a flat shoot, to a vessel 10 connected to pipe 9. The height of liquid in vessel 15 and consequently the operation of the valve 12 is controlled by the height of liquid in vessel 10. An additional overflow branch may be included in cover 2 outside chimney 32.

Title: A mechanism for the automatic variation of the width of knitted fabric in flat knitting machines
IPC: D04B15/36
Filed: 1956-04-24
Abstract: 792,887. Knitting-machines. STOLL, R., STOLL, E., STOLL, H., STOLL, E., and STOLL, G. [trading as STOLL & CO., H.]. April 24, 1956 [April 27, 1955], No. 12497/56. Class 74 (2). At each stroke of the cam carriage of a flat machine, during widening, the nose of the trailing one of a pair of pivoted up-pickers 13, 14, carried by the cam plate, engages the first one (22<SP>11</SP>, say) of jack butts 22<SP>1</SP> corresponding to those needles which are in the lowered inoperative position; and the picker is thereby swung about its pivot 15, against the action of a spring 19, the engaged picker nose being thereby caused to traverse an inclined slot 11 or 12 in the cam plate, so landing the jack butt on the flank of a cam 8 which further advances it to a level 22 and hence the corresponding needle butt to a level 23 which will ensure its passage through the stitch-forming cam system on the next stroke of the cam carriage. By virtue of its rotation about the pivot 15, the picker nose, as it traverses the slot, recedes into it, to release the jack butt at the proper moment. The last part of this rotation, immediately before such release of the butt, is effected by engagement of a sliding latch 20 with a notch 18 in the picker which is thereby held inoperative until released. The leading picker is, at each stroke, moved temporarily to inoperative position by suitable means. When widening is not required the pickers are held inoperative by the latches 20.

Title: Data processing system with checking means
IPC: G06F9/22
Filed: 1966-03-23
Abstract: 1,108,808. Checking arrangements. INTERNATIONAL BUSINESS MACHINES CORPORATION. 23 March, 1966 [7 April, 1965]. No.12712/66. Heading G4A. Test means are provided in a processor for testing checking means therein. In a micro-programme-controlled computer, an arithmetic and logic unit comprises unified circuitry (Figs. 3b, 3e, 3g, not shown) for selectively forming the sum of two 8-bit binary operands or the AND, OR or EXCL-OR function of corresponding bits thereof. Preceding circuitry (Figs. 3a, 3d, not shown) permits addition of 6 if the operands and result are each to be interpreted as two binary-coded-decimal digits and complementing to achieve subtraction. Correction circuitry (Figs. 3c, 3f, 3h, not shown) following said unified circuitry permits selective subtraction of 6 from the result in the decimal case. The chosen operation is done with the operand bits in true form and also in complement form and corresponding bits in the two results are compared in EXCL-OR gates (160, 161, &c., Figs. 3c, 3f, 3h, not shown), an error bit being set in a machine register (MC) if at least one such gate does not produce an output. To test this checking circuitry, a microprogramme routine is initiated by suitably addressing the micro-programme read-only store using console switches. The routine, described in detail and including a loop, successively applies selected constants as operands to the arithmetic and logic unit, the operations AND, OR and add being used, and sets and resets two latches (201, 220) which when set disable AND gates in said correction circuitry and unified circuitry respectively, forcing both the true and complement forms of successive bits (including carry) to both be " one." EXCL-OR- ing of the contents of said machine register (MC) with a constant after each test in the routine determines if the checking circuitry detected the forced error and if not causes a machine stop which is coupled with a routine for indicating the nature of the failure (no details).
