Abstract: 1,250,674. Automatic mixing apparatus. IMPERIAL CHEMICAL INDUSTRIES Ltd. 29 May, 1970 [23 June, 1969], No. 31607/69. Heading B1C. [Also in Division G1] In a method of and apparatus for preparing samples for automatic on-line analysis of a product, e.g. granular fertiliser, at regular intervals a sample of the product exceeding a predetermined weight is automatically drawn from a process, an accurately weighed sample of said predetermined weight is separated from the sample, the remainder being dumped, the weighed sample is mixed with an accurately measured preselected quantity of a liquid in a mixing vessel 14 with a stirrer 15, and the resulting homogeneous solution, suspension, dispersion, or emulsion is passed to a collecting vessel for analysis, the steps being effected in sequence for preselected periods by one or more programmed controllers. The initial sample, which may comprise a mixture of fractions of several samples taken from various points along the process line, is supplied at A to a hopper 1 feeding a vibrated feed trough 2 supplying the pan 3 of an automatic balance. The trough is vibratable at two speeds for coarse and dribble feed rates respectively. The balance arm 4, having coarse and trim weight adjustments 6, 7 has at the end remote from the pan 3 a vane 10 between a lamp and a photocell 11. Initially the vane is below the lamp and photocell, and the feed trough 2 supplies at the coarse rate. As, say, 90% of the predetermined weight, the vane 10 interrupts the light beam, causing the feed trough 2 to be switched to dribble feed. At the full weight, the vane 10 clears the beam again, causing a motor 13 to be energised to pivot the feed trough 2 to a second position where it discharges the remainder of the initial sample, and causing a motor 12 to invert the pan 3 to tip the weighed sample into the mixing vessel 14. Subsequently the trough 2 and pan are returned to their initial positions. Meanwhile, a valve 17 is actuated to fill a pipette 16 with liquid from a tank 18, and to discharge the pipette to the mixing vessel 14. The stirrer 15 is run for a predetermined time, prior to opening the valve 19 to empty. the mixing vessel. The steps may all be in sequence, or some may occur simultaneously. The controller has manual override provision, and includes warning lights which indicate when the full weight has been reached; when this weight has been reached too rapidly for accuracy; and when it has been reached too slowly. If the full weight has not been reached in the time allowed for the weighing step, that step is continued until the full weight is reached, or until a predetermined time has elapsed, the apparatus then being stopped if the weight is still low.

Abstract: 1,264,980. Calculating check digits. RICOH K.K. 14 March, 1969 [29 March, 1968], No. 13503/69. Heading G4A. Digital checking system has a multiplier having a first input receiving a plurality of successive code digits and a second input receiving a plurality of successive weighting digits corresponding in number to the code digits and fed to the second input in a predetermined order, the multiplier being arranged to multiply each code digit by its corresponding weighting digit, an adder connected in cascade with the multiplier to sum the successive products from the multiplier and a store holding at least the last digit which is a check digit. Binary coded decimal digits n 1 -n 4  are fed to a register R N  and via a diode matrix enable one of lines N 0 -N 9 . Weight digits are fed to register R w  and enable one of lines W 0 -W 9 . The two enabled lines enable one of lines M 11 - M 99  which in turn enables a line M 0 -M 9  which causes a binary coded decimal signal of the least significant digit of the product to appear on lines Á 1 -Á 4 . These lines feed Register R M  to enable one of lines A 0 -A 9  and the sum of the previous least significant digits of the products stored in register RA enables one of lines S o -S 9 . The two lines enable one of lines A 00 -A 99  to enable one of lines S o -S 9  so that a sum digit appears on lines α 1 -α 4  which is fed via gates G to register R A . The least significant digits of the products of the code digits and weight digits are thus added and stored as a check digit in register R A . The diode matrices may be modified to consecutively add all digits of the product i.e. for code digits and weight digits equal to 9, 9 x 9=81 is added as 8 + 1.
