Title: Multiplication apparatus
IPC: G06F7/52
Filed: 1962-10-23
Abstract: 987,899. Electric digital calculators. NORTH AMERICAN AVIATION Inc. Oct. 23, 1962 [Oct. 23, 1961], No. 40149/62. Heading G4A. Binary multiplication is effected by adding or subtracting the multiplicand in the various partial products, according to the values of the multiplier digits. The method employed is based on the identity the product N times 2A being calculated by subtracting the products of the multiplicand N with the number A and its "inverse" A<SP>1</SP> (the number obtained from A by replacing each 0 by 1 and each 1 by 0) and then subtracting the multiplicand N in the appropriate order. The process is effected by either adding or subtracting the multiplicand in each partial product position according as the corresponding multiplier digit is 1 or 0, the final step involving a subtraction of the multiplicand N. This method of multiplication enables apparatus adapted for the "non-restoring" method of division to be employed for multiplication also. In the arrangement described, numbers are represented in fractional form with seven significant digits to the right of the binary point, the digit to the left of the point being 0 or 1 according as the number is positive or negative, the significant part of a negative number being the 2's complement of the corresponding positive number. Multiplication is performed two bits at a time, a total of six word times being required to complete the operation. The apparatus includes three recirculatory registers an "N register" 13, Fig. 6, an "A register" 12, and an "L register" 11, the registers being recirculatory registers including bit positions on a magnetic disc (Figs. 1, 2, not shown). During the first word time the multiplier A is shifted from the A register to the L register and during the subsequent operations, the multiplier A is shifted out of the L register 11 and replaced by the high end of the partial product, the low end of the partial product being built up in the register 12. Multiplier digits control the multiplication steps in successive pairs, effective in successive word times. An adder-subtractor 78 adds or subtracts according to the indication in a flip-flop 02 controlled by the first of a pair of multiplier digits, a second addersubtractor (not shown) adding or subtracting according to the value of the second digit in the pair of multiplier digits. During the last bit of each word time the overflow bits are entered into the L register 11. During the final word time, the contents of the A register 12 and the L register 11 are interchanged so that the most significant part of the product is in the A register. The logic required to control the various operations is described in Specification 987,900. Specification 929,878 also is referred to.

Inventor: MCINTOSH BRUCE MURRAY
IPC: D02G1/02
Filed: 1967-09-04
Abstract: 1,207,811. Crimping yarns. IMPERIAL CHEMICAL INDUSTRIES Ltd. 29 Aug., 1968 [4 Sept., 1967], No. 40241/67. Headings D1F and D1W. In a "dammed twist" process for making twist-crimped, filament yarn, filamentary strands which are not intertwisted and each of which comprises at least one filament are led at equal and controlled speeds through feeding and forwarding devices between which the strands have been pre-intertwisted by relative rotation between coaxially aligned guide assemblies, each strand passing through one guide of each such assembly which is symmetrically spaced round a circle in a plane normal to the twisted length of strand, and the strands are deflected through equal angles by the guides. The twist is set, with the strands running and the guide assemblies secured against rotation, by heating and cooling between the assemblies. Melt spun filaments may be drawn between the devices and at least partly before the twister zone. Oppositely twisted strands may be combined to form balanced torque yarns.

Abstract: 1,065,842. Valves. FMC CORPORATION, Oct. 15, 1963 [Oct, 23, 1962], No, 40532/63. Heading F2V. The fluid pressure across the head of a resiliently seated piston 28 is controlled by a pilot valve 90, actuated, via diaphragm 114, from a fluid pressure source. In the Fig. 2 position, the valve 90 is spring urged on to a sealing element 96 so that inlet pressure acts via passages 60, 62 and 66, to equalize the interior and exterior fluid pressures upon piston 28, which is seated by spring 48. Application of fluid pressure to inlet 118 unseats valve 90 to the Fig. 3 position (not shown), whereby fluid flow to the interior of piston 28 is blocked and the pressure therein discharges, via passages 66 and 71 and past check valve 74, to the downstream outlet 14; the piston 28 is thereby unseated when exterior pressure upon the head thereof overcomes the force of spring 48.

Title: Method of electrodialyzing aqueous solutions
Inventor: JUDA WALTER
IPC: C02F1/46
Filed: 1958-12-17
Abstract: 854,095. Electro-dialysis of aqueous liquids. IONICS Inc. Dec. 17, 1958, No. 40642/58. Class 41 In the electro-dialysis of liquids the liquid is passed through a series of diluting chambers alternating with concentrating chambers provided with cationic and anionic permselective membranes, the end chambers of each series only being provided with electrodes, the current is periodically reversed, and the flow of diluting and concentrating liquids interchanged, whereby the membranes are prevented from fouling and clogging particularly the anionic membrane. Brackish waters, sea water, and sugar solutions and similar liquids containing relatively minor amounts of electrolytes, are treated. A suitable apparatus comprises a dimineratiser unit 20 Fig. 2 comprising a stack of chambers bounded by anion permeable membranes A and cation membranes C, with electrode chambers E  1  E 2  at each end. The anode and cathode feeds (which may be tap water or a suitable electrolyte) concentrating and feed liquids and the effluents, are fed through valves Va...Vh to pumps P1...P4, tanks T1...T4, through switch valves V 1 ...V 16  connected to the stack of chambers. Each tank has two pairs of valves. As shown, chambers 1 are diluting, 2 are concentrating, chambers 3 and 4 contain anolyte and catholyte. On reversing the switches S1...S4, the concentrating and diluting chambers are interchanged, by reversing the flow of liquids, and similarly the anode chamber becomes the cathode. In examples using 150 diluting and concentrating chambers, the salinity of sea water was reduced from 35,000 ppm. to 500 ppm with an output of 1000 gals. per day. After 3 weeks the current had fallen from 30 amps to 15 amps; and output fell to 500 gals. per day when current and liquid flows were reversed the original rates were restored. In the treatment of sugar or molasses solution a little acid is added to adjust pH value to 3À5, and dilute salt solution is used as concentrating liquid. Reversal of current and liquid flow is effected at periods of 12 to 24 hours. Specifications 720,002, 772,862, 821,229 and U.S.A. Specification 2,848,403 are referred to.

Filed: 1960-12-05
Abstract: 1,001,261. Automatic feed weighers. M. C. BIGNELL Ltd., and H. E. G. WATTS. March 5, 1962 [Dec. 5, 1960; Sept. 8, 1961], Nos. 41853/60 and 32420/61. Heading G1W. Apparatus for weighing material in solid or fluid form comprises a turntable 1 driven at a controlled speed, a holder 4 for the material arranged eccentrically with respect to the axis of the turntable and a gate 8 responsive to the centrifugal force exerted by the material when this force exceeds a predetermined value. As shown, the turntable 1 carries the holder 4 extending radially outwards, with an axial inlet 6 surrounding the drive shaft 3 and a periphical outlet 9. The wall 21 of the outlet is shaped to enclose a rotatable gate member 8 which comprises three vanes 10,11 and 12. The vanes are so arranged that alternative paths are presented to the material as it moves radially outwards through the holder due to centrifugal force, one of the blades blocking whichever passage is presented. Pins 13, fixed to the turntable 1, are held by springs 14 in engagement with seatings 15 on upright members 16 carried by the gate member 8. When the speed of rotation is such that the centrifugal force has reached a certain value the pressure of the material overcomes the resistors to rotation applied to the member 8 by the springs 14 and the member 8 rotates and allows a batch of material of the required mass or weight to be ejected. The member 8 is then in the position to present the alternative path to the next batch of material. The weight of a batch may be preset by the speed of rotation of the turntable and/or by the radial distance from the axis of the turntable of the axis about which the member 8 rotates and/or by the strength of the springs 14. Various modifications are disclosed. Instead of vanes, a holder may be pivoted on the turntable in such a manner that it swings to discharge its contents at a certain centrifugal force. There may be two or more separate holders, especially for mixing batches: also separate carriers on turntables. For fluids, a valve may be used instead of a gate member, suitable means being provided whereby it is responsive to centrifugal force. The rotatable carrier may be enclosed in a casing, whereby weighed batches of material may be stored until required. The centrifugal force may be used to cut off the supply of material, which makes possible the control of the number of batches. Control can be remote, and may be linked with the operation of other apparatus. Where vanes are used, their rotation may be assisted by air pressure, by which means also the flow of material may be assisted. Centrifugal force may cause electric, hydraulic or pneumatic means to bring the holder to its discharge position. A desired length of strip may be wound by carrying a reel on the turntable so that it has limited radial movement against a spring and operates an electrical contact when enough has been wound on the reel for the radial force theron to have a certain value.

The pipe insert 2 has openings 24, 20 for the passage of warm fluid and openings 25, 21 for cold fluids, mixing taking place in the valve outlet 31. The element 5 has a cylindrical housing having openings 16, 18 for warm fluid, openings 17, 19 for cold fluid and contains a piston 6, or membrane, movable to compensate for pressure differences. Sealing ribs 23 extend around the ends of element 5, circumferentially between openings 16 and 18 and between openings 17 and 19, Fig. 4 (not shown), and sealing ribs 22 bound openings 18 and 19. Element 5 is connected to the operating means by a planetary gear-type system such that rotating handle 7 causes element 5 to move axially to vary the relative amounts of hot and cold fluid passing through to adjust the temperature and rotating handle 8 rotates the element 5 so that the sealing ribs 22 gradually cover openings 20 an 21 to restrict flow through the valve and thereby adjust the quantity. Preferably the sealing ribs 22 and 23 are formed as soft rubber mouldings and since all the movable sealing faces are on element 5, only the element 5 need be replaced when worn.
