Title: Decadic relay adding machine
IPC: G06F7/42
Filed: 1954-10-27
Abstract: 787,185. Digital electric calculating-apparatus. ARITMA, NARODNI PODNIK, and SVOBODA, A. Oct. 27, 1954 [Nov. 6, 1953], No. 31002/54. Class 106 (1). In a calculating machine in which the individual digits of a number are represented by the code 8, 4, - 2, - 1, each denomination includes two sets of electromagnetic input relays, each set having four relays corresponding to the values of the code, an adding network coinprising contacts of the input relays and forming energizing paths for five result-giving relays corresponding to coded values 16, 8, - 4, - 2, 1, and a decoding network comprising contacts of the result relays and having four output terminals for the result digit in the code 8, 4, - 2, 1. Fig. 1 shows one denomination of a decimal adder. Digits are represented by pulses in parallel on lines 19 or 19<SP>1</SP> and 17 which energize combinations of relays 1, 3, 5, 7 and 2, 4, 6, 8 representing values 8, 4, - 2, - 1 respectively. The combination code, Fig. 3, is such that the nines complement of a digit is represented by a switch reversal, e.g. " 6 " would be represented by energization of the " 8 " and " - 2 " relays and " 3 " by de-energization of these relays and energization of the other, " 4 " and " - 1 " relays. The input relays are energized in synchronism with timing pulse A, Fig. 9, and held through hold windings and contacts 1a-8a by a pulse a on line 9. These relays operate contacts to cause appropriate sum relays 11-15 representing values 16, 8, - 4, - 2, 1, to be energized when a timing pulse B, Fig. 9, appears on line 10. Each contact network is connected to that above and below through lines 25, 25<SP>1</SP> and 24, 24<SP>1</SP>, corresponding to a tens " carry " and " no carry " respectively, the lines connecting also the highest to the lowest denomination for endaround carry during subtraction by complementary addition. The networks are such that if a number plus its nines complement are entered, the pulse B cannot pass to lines such as 24, 25 or to any of the sum relays, thus registering zero. The sum relays are held by a pulse b on line 16 and operate decoding contacts whereby when the next pulse A appears on line 18 it will pass to the appropriate one of sum-digit lines (8), (4), (- 2), (- 1) which are connected to output 23 or back to input 19 according to whether switching relay 20 is energized or not. A " memory " relay circuit for storing a digit, and reading it out in direct or reversed (complementary) form under control of a (+) and (-) relay, is described (Fig. 2, not shown).

Patent GB-305733-A (GB)
Title: Improvements in or relating to aerial systems for wireless signalling
IPC: H01Q21/12
Filed: 1927-11-18
Abstract: 305,733. Eckersley, T. L. Nov. 18, 1927. Directive signalling.-Maximum receptive or transmission is effective by an arrangement of two or more aerials adapted to be energized in phase, and so spaced apart that the radiation resistance of the system as a whole is less than the radiation resistance of the separate aerials in parallel. The separation of adjacent aerials may vary from between 0.43 to 0.75 but is preferably 0.57 of the working wavelength. As shown in the Figure, the spaced aerials A, B are tapped to parallel feeders PQ coupled in turn through a transformer T3 to a main feeder F. The impedance of the tappings T, T1 and T, T2 is made equal to the surge impedance of the respective aerials. Maximum radiation or signal strength occurs in a direction at right-angles to the line A, B. The aerial arrangement is distinguished from the known " beam " systems, but is stated to give results comparable to those obtainable from the beam with greater simplicity and less cost.

Title: Improvements in or relating to meters for flowable materials
IPC: G01F15/00
Filed: 1954-10-28
Abstract: 782,837. Electrically-actuated valves. HYDRAULIC RECORDING INSTRUMENTS, Ltd., and HAMBLETT, L. S. J. Aug. 5, 1955 [Oct. 28, 1954], No. 31185/54. Class 135. Apparatus.-The delivery outlet 12, Fig. 1, of a rotary piston meter 11 is controlled by an electrically-operated valve 13 whilst the meter drives a two-way switch 19, Fig. 5, connected by leads 20-22 to a control unit 23, Fig. 1, comprising a dial and a shaft to which latter is connected a pointer 26 as well as a preset cam 27, Fig. 5, and a reset cam 28; the cam 27 is angularly adjustable relative to a datum, which is usually represented by the dial zero whereupon a cam dwell 29 is aligned with the latter. The quantity of material passed through the valve in one revolution of the cam 28 is dependent upon the amount a dwell 30 on cam 27 is moved counterclockwise from the datum. The cam and dial shaft is rotated clockwise by a ratchet wheel actuated by a uniselector 39 that is in circuit with a first relay 40; a second relay 43 is also provided which is in series with the switch 19 and a capacitor 44. Operation.-Upon closing a starting switch 41 the relay 40 is energized thus closing contacts A2 and A3 and opening contacts A1 whereupon contacts A3 complete a circuit to open valve 13 and cause operation of the meter. Contacts A2 maintain the supply across relay 40 after the switch has been released. The operation of the meter effects actuation of the switch 19 which thus connects the capacitor alternately across the D.C. supply and the coil of relay 43. Whilst the capacitor 44 is discharging during the operating pulse, it energizes the relay 43 and closes contacts B1 to bring about a one-tooth movement of the ratchet wheel. When a follower 45 enters the dwell 30 contacts 46 are opened so deenergizing the relay 40 and hence closing the valve 13; closure of contacts A1 completes a circuit to the uniselector so that rotation of the cams 27 and 28 continues until the swell 29 is restored to datum whereupon the follower 47 enters the dwell 29 and causes contacts 48 to open and break the circuit to the uniselector. The control circuit is open and will remain so until the switch 41 is again operated. The control unit may be remote from the meter and valve. Specifications 627,505 and 735,276, [Group XXVI], are referred to.
