Abstract: 549,487. Treating solids with liquids. DAVISON CHEMICAL CORPORATION. March 13, 1941, No. 3446. Convention date, Jan. 15 [Class 82 (i)] [Also in Group III] Phosphoric acid is obtained by treating a bed of calcium superphosphate (by addition of sulphuric acid) and passing water through the bed. The process is carried out in a series of bleaching tanks, containing superphosphate, which may suitably be in the form of hard porous nodules, and should not pack when in deep layers, the solution from the first tank containing sulphuric and phosphoric acids being passed into the second and so on. Sulphuric acid may also be introduced into an intermediate tank of a series in addition to the solution from the preceding tank. The tanks which may suitably be eight in number are constructed as shown in Fig. 4 and comprise a steel casing 10 having an acid resistant brick lining 11 and an interlining 12 of plastic material including bitumen or rubber. A perforated wooden false bottom 13 is spaced from the base of the tank and carries a coconut matting 17. A shallow box 21 at the top of the tank serves as a mixing means for liquid to be supplied from inlets 57, 67, 73. The inlet 57 is supplied with water from a conduit 51; the inlet 57 supplies acid from a measuring box 63 connected with an acid conduit 52; the inlet 73 is supplied with liquid from preceding tanks flowing from a swinging elbow 70 and a pipe up which it is forced from an outlet 25 at the base of a tank by an air lift 27 supplied with air from a conduit 54. The air lift is controlled by a float 28. Receivers 78, 79 are connected as shown to a conduit 53 and to the pipes 25, 27 and are selectively accessible to the liquid from the outlet 73 so that liquid from a given tank may be passed alternatively to a mixing box 21, to a receiver 79 for passage to the bottom of the next tank or to the conduit 53 for transmission to a collecting tank or even to bypass a particular tank. A manhole 22 is provided for removal of spent superphosphate. Tanks for sulphuric acid and water to be supplied to the conduits 52, 51 are provided with known control devices for regulating head and rate of flow. A feed hopper and associated travelling belt are provided for the supply of superphosphate to the several tanks. The several conduits are provided with means for controlling the rate of flow of liquid. The arrangement permits the selection of any of the tanks as the first and last of an operative series.

Abstract: 588,344. Photo electric control of statistical apparatus. BRITISH TABULATING MACHINE CO., Ltd. (International Business Machines Corporation). Feb. 12, 1945, No. 3509. [Class 40 (iii)] [Also in Group XIX] A machine for handling cheques, record cards, &c. comprises means for aligning a cheque before feeding it through a sensing or recording device. In its initial passage through the machine, after proper alignment by mechanical means, a short black line is printed on the cheque parallel with its shorter edge. During subsequent feeding operations, the lateral alignment of cheques bearing these locating lines may be controlled by a circuit including a photo-electric cell which receives light reflected from the surface of the cheque. The rotation of an edge cam 43 allows a spring- urged follower 44, together with a sleeve 45, collar 48, and feed rollers 22L, 22R, with the card 10 gripped between them, to move gradually to the left. When the control line on the cheque passes under the photo-cell, the change in current, suitably amplified, energizes a relay 55 which, by rocking a pawl 56 into engagement with a rack 57, stops the lateral movement.

Abstract: 646,569. Pulse discriminating circuits. STANDARD TELEPHONES & CABLES, Ltd. Feb. 7, 1947, No. 3704. Convention date, Nov. 30, 1945. [Class 40 (vi)] Secondary pulse trains are derived from an input-wave by slicing at different amplitude levels, the derived pulses being delayed so that those corresponding to the desired pulses in the input wave are superimposed and exceed the bias level of a clipping amplifier. Pulse width selector, Figs. 1 and 2. The input pulse train 1, with desired pulses 6, 7 and unwanted pulses 8 ... 12 is fed to a double clipper 3 utilizing a biassed diode 15 to pass a segment A giving pulse train 19. This train is fed to a pulse width selector 21 of the type described in Specification 592,789, the output train 27 being fed through a variable delay line 29 to the mixer clipper stage 30. In a similar manner, the double clipper 4 selects segment B to give pulse train -32, the width selector 34 producing train 35. The biasses of the valves 38, 39 are adjusted so that only pulses 46, 47 exceeding the bias levels cause the valves to conduct, the common lead adding the pulses to give the train 44. The delay is adjusted until pulses 46 and 47 are superimposed to give pulses 48. The unwanted pulses are removed by the clipper 49 operating with a bias level 51. Leading edge slope selector, Figs. 3 and 4. The input wave 54 with desired pulses 93, 94 having the same slope leading edges and unwanted pulses 95, 96, 135, is fed to double clipper 56 to select segment A to produce a train 60. After differentiation by capaciter 63 and resistor 64, train 65, the wave is clipped at level 69 by valve 67 and passed to the width selector 71, wave 72. In a similar manner, the double clipper 57 selects segment B, wave 75 which is differentiated, wave 78, clipped at level 79 and then fed to the width selector 80 to produce the wave train 81. After passing through the delay device 82 the wave is fed to a mixer clipper 74 similar to that shown in Fig. 1. By adjusting the delay, the peaks 86, 87 exceeding the bias levels 84, 85 of the mixer valves are arranged to add to give the pulses 91 corresponding to the desired pulses. The unwanted pulses are removed by clipper 90 biassed to the level 92. By the addition of a phase inverting value, Figs. 5 and 6 (not shown), the discriminator will operate on the slope of the trailing edges. Combined system. In a modification, Figs. 7 and 8 (not shown), each segment is fed to a leading edge slope selector, a trailing edge slope selector and width selector. The outputs from the selectors, delayed where necessary are fed to a mixer clipper from which is derived the desired pulses.
