Title: Concentrating nitric acid

Filed: 1960-12-21
Abstract: 975,324. Concentrating nitric acid. AMERICAN METAL CLIMAX Inc. Dec. 21, 1960 [Dec. 24, 1959], No. 43898/60. Drawings to Specification. Heading C1A. A method of concentrating nitric acid in a nitric acid-water solution comprises dissolving potassium nitrate in the solution and removing vapours therefrom until strong nitric acid remains. The effect of the KNO 3  is that the water vapours produced from the solution contain less nitric acid vapour than azeotropic vapours formed from nitric acid in water alone, so that the nitric acid solution remaining has a concentration greater than azeotropic. The vapours may be removed by fractionation in a column containing a series of trays. Weak solution is introduced at a point below the trays and is fractionally distilled so that water vapours are removed overhead and strong nitric acid solution of KNO 3  recovered below the trays. The solution recovered may be further distilled to give vapours which on fractional distillation yield 85-100% nitric acid overhead. The invention is illustrated in detail as part of the process for producing chlorine from the reaction of nitric acid with a chloride of potassium, sodium, hydrogen, or a mixture thereof which is the subject of Specification 975,325.

Title: A binary adder for an electronic computer

Filed: 1962-11-23
Abstract: 1,022,143. Binary adders. TELEFUNKEN PATENTVERWERTUNGSGESELLSCHAFT. Nov. 23, 1962 [Nov. 25, 1961], No. 44398/62. Heading G4A. In a parallel binary adder in which a modulo 2 sum of more than three operands is formed in a first step and carries are reduced in subsequent steps, the carries are supplied to higher order stages as operands in the subsequent steps of the addition, together with any further operands to be added. The carry reduction time is thus reduced. First embodiment, Fig. 1 (not shown).-Four summands are applied during the first step to bistable circuits 1-4, each of whose outputs is applied to each of four threshold devices 5-8, which produce an output when 1, 2, 3 or 4 respectively of their inputs are "1," to provide, for the i'th stage, a sum bit U<SP>0</SP>i, applied to the bistable circuit 1, which is thus effective as an accumulator; a carry U<SP>1</SP>i applied to the bistable circuit 4 of the (i + 1 )th stage; and a double carry U<SP>2</SP>i applied to the bi-stable circuit 3 of the (i + 2)th stage. All the bi-stable devices are centrally synchronized by a clock pulse source (not shown) and during subsequent steps an additional summand can be applied to the bi-stable circuits 2. Second embodiment, Fig. 2 (not shown).- Seven summands are applied during the first step to bi-stable circuits 17-23 each of whose outputs is applied to each of seven threshold devices 24-30 which may be as described in Specification 1,002,575. The threshold devices 24-27 produce an output when precisely 1, 3, 5, 7 respectively of their inputs are " 1 " to produce a sum bit U<SP>0</SP>i. The devices 28, 29 produce an output when 2 or 3 and 6 or 7 respectively of their inputs are " 1 " to produce a carry bit U<SP>1</SP>i. The device 30 produces an output when from 4 to 7 of its inputs are " 1 " to provide a double carry bit U<SP>2</SP>i. In subsequent steps, four further summands can be applied to the bi-stable circuits 18-21. Third embodiment, Fig. 4 (not shown).-This circuit can add seven operands, as in Fig. 2 (not shown), but instead of threshold devices, a three-stage binary counter 66-68 is employed. Fig. 4 (not shown) shows the i'th stage of the adder, input operands being gated from terminals 44-50 by a synchronizing pulse train of frequency f/8 (where f is the machine clock pulse rate) to bi-stable circuits 58-64 which are arranged as a shift register stepped by pulses of frequency f. The output 65 of the shift register is connected to the counter 66-68 which counts the number of " 1 "s in the input operands and provides appropriate sum and carry signals U<SP>0</SP>i, U<SP>1</SP>i, U<SP>2</SP>i.

Abstract: 1393758 Actuators BOEING CO 3 Oct 1972 [29 Dec 1971] 45487/72 Heading B8J An actuator 32 having redundant critical components is connected between aircraft wing 34 and rotor 36 to tilt the rotor 36 about point 38 between vertical, hovering position and horizontal, conventional flying position. Identical first and second drive mechanisms 40, 42 are mounted on a common, non-rotating screw 44 and are shown respectively connected by bolts 56 to the wing 34 and the rotor 36. Mechanism 40 includes a ball nut 46 threaded on the screw 44, a no-back locking device 48, a differential 50, an electric motor 52 and a housing 54. During normal operation the motor 52 drives input gear 62 of the differential 50 through shaft 58 and gear 60 and the differential has two outputs: one driving transmission shaft 70 and the other driving the gear 72 and thus the nut 46 through gear 76, shaft 74, no-back device 48 and gear 75. The shaft 70 interconnects the mechanisms 40, 42 and is splined to allow free, longitudinal passage through teeth of gears 51 of the differentials 50, stops 71 preventing complete passage. If the ball nut 46 of mechanism 42 seizes, then the rotary output of the motor 52 of the mechanism 42 passes to the mechanism 40 through its associated differential 50 and the transmission shaft 70. The shaft 44 must, in this case, be at least twice the length of the desired travel to ensure the maximum design distance can be traversed. A power loss to the motor 52 of the mechanism 40 results in the motor 52 of the mechanism 42 driving the mechanism 40 through the shaft 70. If, in addition, shaft 70 fails then the actuator 32 continues operation, by means of the mechanism 42, though at half-speed. If the ball nut 46 of mechanism 42 seizes and the motor 52 of the mechanism 40 fails then the actuator 32 continues to operate, but at halfspeed.
