Patent GB-680546-A (GB)
Title: Improvements in or relating to electrical calculating machines
Inventor: HITCH FREDERICK ALEXANDER NIGE
IPC: G06F7/52
Filed: 1949-07-27
Abstract: 680,546. Digital electric calculating-apparatus. NATIONAL RESEARCH DEVELOPMENT CORPORATION. Sept. 7, 1950 [July 27, 1949], No. 19801/49. Class 106 (i). [Also in Group XXXVI] In an electric calculating-apparatus, digits are represented by the frequencies of alternating current pulses. In the adder shown, corresponding digit pulses (having frequencies proportional to 10-19 representing 0-9 respectively, as indicated) are fed simultaneously from number stores S1, S2. The output from S2 modulates a frequency (90) at Ml and the outputs of 81 and M1 are mixed at M2 and the upper side-band frequencies (110)-(128) are selected by band-pass filter F1 and sent to further filters F2, F3, which separate the frequencies representing 0-9 from those representing 10-18. The outputs of F2, F3 are demodulated, by the frequencies indicated, in circuits M3-M7, selected by a carry switch C such as a relay which is temporarily thrown over from the position shown by a pulse from F3 delayed one inter-digit period by D1, and for consequent carry, if the next digit pulse from F1 is a " 9," by a delayed pulse from circuit M3 and filter F5. The outputs of F5 and M4- M7 are passed through filter F4, and possibly a shaping circuit (not shown), to store S3 which registers the sum. Subtraction may be similarly performed. Multiplication may be effected by repeated addition.

Title: Improvements relating to weld inspection means
IPC: G07C3/14
Filed: 1959-06-12
Abstract: 850,729. Ultrasonic inspection devices. STEWARTS & LLOYDS Ltd. June 12, 1959 [Dec. 23 1958], No. 20136/59. Class 40(7). In a development of ultrasonic apparatus for inspecting a longitudinal seam weld as described in Specification 850,728 the inspection devices are supported on a carriage which is mounted on a yoke for oscillation in two planes and the yoke is mounted on a support for limited reciprocation toward and away from the seam weld. The upper surface of carriage 81 has recesses 89 into which tips e.g. 56 of shafts 55 extend, thus limiting carriage oscillation in a horizontal plane about the axis of a shaft 72. The carriage can also oscillate in a vertical plane about the axis of a shaft 60 and this oscillation is limited by spacing the tip ends from the bases of the recesses. Limited reciprocation of yoke 25 toward and away from the seam weld in tubing 11 is accommodated by bushings in columns 50 surrounding shafts 55. By these means carriage guide rollers 65, 66 astride the weld are enabled to follow surface distortions on the tubing and vertical and horizontal deflections thereof. Crystal transducers 15, 15<SP>1</SP> thus remain fixed relative to the tubing. The invention may be applied to the single transducer apparatus described in Specification 849,194.

Title: Improvements relating to exhaust steam injectors
IPC: F04F5/46
Filed: 1926-08-16
Abstract: 259,167. Metcalfe, R. D., and Metcalfe, J. C. Aug. 16, 1926. Fluid-actuated valves. - The exhaust-steam valve e of a Giffard injector has two seating faces adapted to contact automatically with seatings g, h respectively. The valve-stem i passes through the head k of a cylinder i into a cavity in a piston j. When working with exhaust, live steam is passed into the cylinder i to force the valve e to mid-position; when the injector action is to be stopped, the live steam is exhausted from the cylinder i and the exhaust forces the valve on to its seat g. When in operation, the piston j abuts against a seat on the head k to prevent leakage into the injector. Specification 223,983, [Class 71, Injectors &c.], is referred to.
