Title: Binary square root mechanization
Inventor: HERTZ THEODORE M
IPC: G06F7/552
Filed: 1961-03-27
Abstract: 923,446. Digital electric calculating-apparatus. NORTH AMERICAN AVIATION Inc. March 27, 1961, No. 11154/61. Class 106 (1). Electrical apparatus for calculating square roots utilizes the binary equivalent of the normal pencil-and-paper method, each root digit being assumed to be " 1," but if the corresponding subtraction results in a negative quantity, the " 1 " is replaced by an " 0 " and the subtrahend added back, this addition being combined with the next trial subtraction in one operation. The Specification describes the mathematical justification for the method The apparatus described comprises three circulatory registers A, B, C, each composed of a seven bi-stable transistor flip-flop stages combined with 22 storage bit positions on a rotating magnetic disc which serves also to induce timing pulses for the apparatus. As described, each circulatory register stores seven significant bits, and a word time is equal to five bit times. The square rooting operation is controlled by bit and word timing counters, each comprising three binary stages (Fig. 7, not shown). Fig. 8 shows schematically the progress of data in the registers A, B and C during the square rooting operation. The operand is entered into the A register and during the first word time W, shifted to the B register. During the last bit of each word time and the first bit of the next word time the two most significant digits of the operand are transferred from the B register to the A register, as indicated by arrows 54, 50. The trial root digit, which is always " 1 is now inserted in C 1  and subtracted from the contents of A 1 , the difference being inserted into A 7  at bit time T 2  of word time W 2 , the subtraction being repeated during each bit time of word time W 2 , the final subtraction during the last bit time T L  indicating the sign of the difference. During subsequent word times, C 1  is subtracted from A 1  if the previous subtraction resulted in an " 0," and added if a " 1 " resulted. During word time W 3  and all subsequent word times, information is inserted in C 1  during bit times T 1 , T 2  thereof, which information is received from the logical circuitry (Fig. 10, not shown), as determined by the mathematical equations of the operation. The root required is built up in the register C and at the completion of the operation may be transferred to the register A for output purposes.

Title: Improvements in or relating to antenna structures, particularly for radio direction finding systems
IPC: H04L27/04
Filed: 1938-04-12
Abstract: 498,985. Directive wireless signalling. LORENZ AKT.-GES., C. April 12, 1938, No. 11220. Convention date, April 12, 1937. [Class 40 (v)] In a navigational system of the overlapping - beam type, as described in Specification 405,727, the relays A, R of the reflecting dipoles are controlled, through an auxiliary relay H (the windings of all three relays being in a common circuit) and associated "timing" resistances, so as to ensure clear-cut keying and a "smooth" continuous note along the equi-signal zone. Specification 431,929 also is referred to in this connection. The main key T, Fig. 1, energizes the auxiliary relay H which operates contacts h1, h2 through resistances a, b controlling the attraction, and resistances c, d controlling the retraction of the main relays A, R. The resistances are graded so that relay A attracts its armature slowly and drops it quickly, whilst relay R does the reverse. In this way a short interval occurs during which both the reflecting dipoles are out of action. The adjustment and timing of the relays A, R can be checked by the test circuit shown in Fig. 2, The arm 6, 7 of the bridge is only opencircuited during the interval when neither of the reflecting dipoles is operative. During this time, one or other of the condensers C1, C2 is charged up from the battery B1 through the resistances R1, R2, according to the position of the switch S2, and the lamp G glows. A switch S1 allows either of the relays to be tested independently of the other.

Abstract: 1,218,398. Rail brake control. E. GARBERS, T. KLOTZEK, and E. SPINGIES. 8 March, 1968 [9 March, 1967], No. 11398/68. Heading B7N. In a braking arrangement for free rolling rail vehicles a rail brake 2 is switched on or off if a vehicle speed is above or below a set value as determined by a device 3 in advance of the brake and, when switched on, is released when the vehicle speed drops to the required release speed. Two spaced wheel detectors in unit 3 determine a time period which is a function of vehicle speed and this is compared with a fixed time setting stored in unit 5. When the measured time is less than the fixed time setting a signal is applied to the brake control unit 6 to apply the brake. When the vehicle enters the brake a succession of wheel monitors 7 spaced apart by the minimum axle spacing ensure that the monitoring control 8 is influenced only by a passing wheel and also switch on a timing element 9 set to a time which is a function of the required leaving speed. Between the monitors 7 wheel-operated time pulse generators 10 are disposed and when the time between two generated pulses exceeds the time set in the element 9 a signal is supplied to release the brake. Unit 11 acts to switch off the brake when vehicles pass in the opposite direction. In a second arrangement, Figs. 2A, 2B, 2C (not shown), two rail brakes are provided and the speed determining means in approach to the brake includes two time setting devices whereby if the vehicle speed exceeds a first high value then the first brake is switched on and this switches on the second brake if the vehicle's speed has not been reduced to the required leaving speed before leaving the first brake, if the speed exceeds a second lower value then only the second brake is switched on and if the speed is below the second lower value then both brakes are switched off.
