Title: Analogue computers
IPC: G06G7/36
Filed: 1974-02-19
Abstract: 1467484 Solving polynomials ROSEMOUNT ENG CO Ltd 31 Jan 1975 [19 Feb 1974] 7519/74 Heading G4G An analogue computer for solving polynomials comprises a high-gain amplifier 32 in which the added outputs of several multiplication modules 1, 2 &c. representing values of the terms of the polynomial are compared to a reference signal, the multiplication modules being responsive to a common multiplier signal generated by the amplifier, the gain of the amplifier being such as to minimize the difference between its inputs, whereby the common multiplier signal is caused to represent the unknown variable. Typically, the computer may solve for d (density) in the gas equation: where P and T represent absolute pressure and temperature. The modules 1, 2, 3, 4, 5, 6 are identical and each comprises an (electronic) switch 22, a smoothing circuit 20, 21, a buffer amplifier 23 of unity gain and a potentiometer 26. The modules 1 and 4 are fed respectively with signals R REF  and T<SP>1</SP>=T.V REF , each of the further modules 2, 3 ar 5, 6 being connected to the output of the preceding one. If f is the pulse repetition frequency of the pulsed control signal fed on line 37 in common to all the switches the outputs of modules 1, 2, 3 (at Z, Y, X) are proportional to Af, Bf<SP>2</SP>, Cf<SP>3</SP> and of modules 4, 5, 6 (at W, T, S) to DTf, ETf<SP>2</SP>, FTf<SP>3</SP> with the same constant of proportionality. The coefficients A, B, C, D, E, F are set by adjusting the potentiometer 26 of each module. Signals representing negative terms are applied to terminals 38, added to a signal P representing pressure and applied to the inverting input of a unity-gain amplifier 30. Signals representing positive terms are applied to the inverting input of high-gain amplifier 32. The resistances 31, 39 are made equal to the resistances 24 whereby the input to the amplifier is a signal which represents the expression: where the summations represent respectively the negative and positive terms of the polynomial. This signal is applied as negative feedback and is constrained to a condition of equality with the signal on the non-inverting terminal which is nominally zero. Under these conditions, the output from terminal Z is proportional to d. The gain of the amplifier 32 is such that a small change in input causes a swing between logic 0 and 1, and this output is fed to the input of a D-type flip-flop 35 clocked at a constant frequency by a clock 15. The latter may be replaced by a mass flow meter having a pulsed output. A signal proportional to both flow rate and density and thus representing mass flow rate may be produced by gating the switching output signal of the flip-flop with the clock signal in an AND gate. The switches 22 may each consist of a pair of FET's controlled by the switch driver 36 (see Fig. 5, not shown).

Abstract: 733,825. Treating sewage; separating mixtures of liquids and solids by gravity. HARTLEY, C. J. March 19, 1954 [March 19, 1953], No. 7553/53. Classes 46 and 111. Travelling scraper apparatus for sedimentation tanks comprises a scraper blade which is automatically lifted and lowered at opposite ends of the tank by means of actuating mechanism from side tracks arranged along the side walls of the tank. Gantries 11 which support the scraper blades 29, run on side rails 43 and carry on depending brackets 15, 33 hinged arms 18 which support rollers 20 running on upper and lower tracks 27, 25. During the inoperative period they run on the upper track 27 and at the end of their passage run down a sloping end member 28 on to the lower rail 25. The sloping members 28 are hinged at 37 and counterweighted at 29 to return to the horizontal when freed from the weight of the rollers 20 which now return beneath them along the lower track 25 having lowered the scraper blade 29 to its operative position through a connecting link 35, the blade-supporting arm 18 being pivoted at 31 to the bracket member 15. At the opposite end of the tank, above a sludge-collecting trough, a hinged slope 26 is displaced by the roller 20 which on reversal of direction rides up the slope to the upper rail 27, lifting the scraper blade 29 clear of the floor of the tank. The rail 25 is parallel to the flow of the tank and both rails are arranged in recesses in the side walls of the tank. Stops may limit the drop of the scraper blades. In a modification, a division wall between two tanks supports a set of guide rails 27, 25 on each side and the running rails 43 support the gantries in cantilever fashion over the respective tanks. Specifications 482,379 and 483,582 are referred to.

Filed: 1969-02-12
Abstract: 1,263,523. Speech synthesis. RCA CORPORATION. 12 Feb., 1969 [26 Feb., 1968 (2)], No. 7608/69. Heading H4R. A speech synthesizer has a library of phonemes stored at selected locations of a data store to be read out in any desired sequence to synthesize desired audible information. Each phoneme is truncated at the beginning and/or the end to provide continuity of formants across the junctions between the phonemes in the desired sequence. The phonemes are read out in sequence as determined manually, by punched card, paper, or magnetic tape, or computer output. Each phoneme to be reproduced is represented by three numbers, one defining the position of the phoneme in the library and the other two the beginning and end respectively of the desired portion of the phoneme. Preferably the phonemes are stored in digital, i.e. pcm, form on a magnetic drum with core memories used as an intermediate store during reading in and reading out of the stores. Fig. 9 shows a system used for recording phonemes the analogue waveforms of which are fed as 7 bit pcm signals into a core memory A. The core memory can store 4096 seven bit signals which represent one phoneme. The signals are fed into the core memory in defined locations commencing when a record command pulse 707 is received. When the core memory is full, flip-flop 709 is tripped and further storage ceases. After an index pulse is received from the drum 21 the core memory is read out in predetermined sequence to store on the drum 21, in locations defined by the sector pulses permanently recorded on the drum, the digital signals defining the phoneme. Further phonemes are recorded in further tracks of the drum. Fig. 10 shows apparatus for reading phonemes from the drum 821 under manual, 831, or paper tape, 833, control. The phenomes requested by the manual or paper tape control are read alternately into the core memories 17 and 827 and while one phoneme is being read into one core memory the desired portion of the previous phoneme, as defined by the second and third numbers read out of the manual or paper tape control, is read out from the other core memory, functions of the core memories being interchanged as soon as the phoneme has been read out of the core store for reproduction. Reading in from the drum to the core store takes place faster than reading out providing allowance for the truncation of the reproduced phoneme. It is suggested that the phoneme might be recorded in analogue fashion on the drum.
