Abstract: 1,053,309. Recording time-dependent variables by electrolysis. NATIONAL RESEARCH DEVELOPMENT CORPORATION. Oct. 8, 1965 [July 9, 1964], No. 28408/64. Heading C7B. [Also in Division G1] Variations in a time-dependent variable are recorded by electro-deposition of two distinguishable materials in a composite layer under constant plating current, the two materials being deposited in accordance with the variable, thus representing the variations. A suitable apparatus is provided with two anodes one of which has a temperature sensitive device, whereby a variation in temperature switches part of the plating current from one anode to the other. More than 2 anodes may be used. The deposited composite layer is then treated with a flowing electrolyte which dissolves off succeeding layers in inverse time to the deposition, and the successive electrolytes are analyzed for the two components. One anode may be Ni and the other an isotope thereof, when the analyzer consists of a radioactivity detector; or cadmium and copper using a polarograph. A glass or ceramic cylinder 11 has mounted on the inner surface the two anodes in the form of regularly spaced interleaved fingers, and a cylindrical metal cathode 21 centrally disposed and spaced 0À05 cm. from the inner wall 11. The cell space is filled with nickel plating bath, and current is applied at low C. D. to electrodes 31, 32. A low voltage imposed A. C. forms a smoother deposit. When deposition is completed, an electrolyte passes in at 29 and current is reversed, the cathode then forming the anode. The electrolyte charged with deposited metal passed out at 30 to an analyzer. Preferably the D. C. applied to the anodes is switched every 10 secs., the conducting period at each anode depending on the time-dependent variable. The apparatus may be used to determine changes in skin temperature and heart beat.

Abstract: 1,227,248. Door closing device. OY WARTSILLA AB. 20 Aug., 1968 [21 Aug., 1967], No. 39682/68. Heading E2M. [Also in Division F2]  A fluid-braked door closing device has a piston 2 screw-threadedly engaged by a cylinder 1, the piston having a fluid chamber 4 which communicates with the cylinder via a non-return valve 8 and a return duct provided with an adjustable throttling means 13 which may be operated from outside the device. There is also a constant throttling means provided by an annular gap 10 between the piston and cylinder and an opening 11 in the piston wall. Movement of a door attached to the arm 7 causes rotation and thus axial displacement of the piston so that fluid flows from the chamber 4 to chamber 5 via valve 8. When the door is released, a spring 9 urges the cylinder I back to its initial position relative to the piston 2, fluid returning to the chamber 4 via ducts 12 and 11. The screw 13 may be made of a material having a greater coefficient of expansion than that of the piston so that the throttling effect and thus the closing speed of the door remains substantially unchanged with changes in temperature.

Abstract: 1,228,350. Frequency measurement. BECKMAN INSTRUMENTS Inc. 29 May, 1969 [31 May, 1968], No. 27313/69. Heading H3A. A frequency discriminator of the type in which constant width pulses are produced and fed to an averaging circuit includes a highfrequency oscillator 27 whose output is fed to a bi-stable 33 and a counter 34 in response to the input signal at 30, the counter 30 initiating a reset pulse at a predetermined count which resets bi-stable 33 to initiate an output pulse. In a system for measuring the speed of a centrifuge rotor, the output from a transducer coupled to the rotor is fed, via a frequency divider if required, to the input 30 of the frequency/ voltage converter. The first pulse to arrive sets bistable 24 to open NOR gate 26, and feed pulses from oscillator 27 to bi-stable 33. The first pulse from oscillator 27 sets bi-stable 33 which initiates an output pulse on line 31, and also opens NOR gates 28. Subsequent pulses from oscillator 27 are then fed to counter 34 and, at a predetermined count, an output pulse from the counter resets bi-stable 24 which in turn resets bi-stable 33 to terminate the output pulse. The cycle repeats at the next input pulse at 30. The constant width pulses on line 34 are fed to integrator 23 via a pulse amplifier Q 1 , Q 2 , Q 3 .

Abstract: 1,258,601. Telephone exchanges. WESTERN ELECTRIC CO. Inc. 2 Jan., 1969 [3 Jan., 1968], No. 280/69. Heading H4K. [Also in Division G4] The invention relates to a stored programme data processor for use in controlling telephone exchanges and capable of performing nested subroutines. Instructions are obtained from a programme store under the control of a counter normally incremented by 1 to perform the base programme series of instructions (Fig. 5). If a jump occurs the next address is gated into an address register PA from a register IP. If a subroutine is reguested a Transfer and Save Address (TSA-Y) is obtained which causes the PA address to be written into a call store CS having 16 blocks each capable of storing 8 words. The block is determined by the contents of a counter HG which holds 0001 when the base programme is being executed and is decremented by 1 upon the execution of each TSA command so that the PA address is written in a fixed location in block 0000 of the call store. The subroutine to be followed will then contain appropriate Hold X Register address HX instructions causing the contents of certain registers specified by the instruction to be stored in selected locations in the selected block. At the end of the subroutine the addresses are returned and counter HG incremented by 1. If a subroutine requires a further subroutine the HG counter is decremented to select a further block in the Call Store and the contents of the required registers are again stored. A maximum of 16 subroutines may be nested in this way. Figs. 7 to 11 (not shown) illustrate the circuit causing transfer of the address and, Fig. 4 (not shown), illustrates the clock and command timing pulses required during the operations. The switching network of the telephone offices is controlled by a call processor to establish communication connections between lines and trunks to service circuits that may include digit receivers, dial tone supplies and other service circuits utilized for serving calls. Outgoing and tandem call connections may be established.

It is shown that superelevation # 0  and time of flight t f  for a gun and projectile may be represented by # O  =  #n f#(R/Rn) and <SP>t</SP>f =  tn f t (R/R n ) where R is the range, and where   # n , t n  and the normalizing factor R n , are dependent upon, and the functions f# and f t  are independent of, the particular ammunition and atmospheric conditions, whereby a computer may be employed in which allowance for change in ammunition or atmospheric conditions is effected wholly by adjustment in simple multiplying circuits for generating R/R n , # n , and t n , the function generators for fe and f t  remaining unchanged. The range R is fed to a multiplying circuit 20 (and Fig. 2, not shown) which includes an operational amplifier having a plurality of n parallel, selectable input resistance branches, each of which corresponds to one type of ammunition and includes one of a plurality of n-FET transistors. The transistor in that branch corresponding to the given ammunition is turned on to switch in that branch and thereby multiply the range signal R by the normalizing factor 1/R n , determined by the ratio of the feedback resistance of the amplifier to the resistance of the selected branch. Each of the function generators 22, 24 (and Fig. 3, not shown) consists of an operational amplifier to the input of which is applied both the normalized range signal R/R n  via a first resistance network, and a bias voltage via a second resistance network, successive branches of each network being switched into circuit by a break-point selector as the signal R/R n  passes through a sequence of increasing voltage values. The first network  determines, by the ratio of its effective resistance to the feedback resistance of the amplifier, the slope of the amplifier output versus R/R n  graph, while the second network determines the (produced) intercept on the abscissa: the resistances of the network branches are chosen such that the resulting graph formed by successive linear segments of increasing slope and intercept approximate the function f# (R/R n ) or f t  (R/R n ) for generators 22 and 24 respectively. The outputs of these generators are then multiplied by # n  and t n  respectively, by circuits similar to circuit 20, to give # 0  and t f , and these values may themselves be multiplied, in further similar circuits-27 and 29, by ammunition and atmospheric dependent terms to give the ballistic drift # o  and crosswind coefficient <SP>K</SP>ow.
