Title: Sample analysis apparatus and method
IPC: G01N33/483
Filed: 1965-11-04
Abstract: 1,117,705. Automatic identification; analysis and documentation of substances. TECHNICON INSTRUMENTS CORP. 4 Nov., 1965 [27 Nov., 1964], No. 46708/65. Heading B1X. The automatic identification, analysis and documentation of a substance, e.g. blood, is effected by providing a supply container and a sample container both containing the same substance and having indicia identifying one to the other, placing the sample container in a conveyor sampler 10, at a first station 20 taking off a sample through an off take tube 22, analysing the substance in apparatus 24 and after converting the resulting signal into digital form at 36 a card punch 38 printing the analysis result on a card, the sample container having meanwhile passed to a second station where a read out wire mechanism 42 feeds a signal dependent on the indicia of the container to a digital code converter, the card punch 38 then printing the identification number on the card onto which the analysis results of that particular sample have been printed. A computer 54 determines the blood type from the card fed to it and punches this by pinch 56 on this or a new card, which is then fed to a sorter 58. The sorter is controlled by a read out mechanism 60 similar to mechanism 42 and a code converter 62. Each blood carrier is brought to the mechanism 60 and the sorter 58 then sorts the cards until the one bearing the correct identification number is sensed. The blood type shown on that card is then printed by printer 68 onto the identification card of the correct supply container. The indicia common to both a sample and a supply container comprises a notched edged card (Fig. 2, not shown). Figures 2 and 3 combined represent a second system in which the sample container is centrifuged to separate the blood into an upper plasma portion and a lower red cell portion, each portion being then divided into form sub-portions for analysis. The sub-portions are treated with anti-A serum &c. and tested thereafter for optical density which is established by respective potentiometers. As in Fig. 1 the results of the analyses are finally printed together with the identification number on a card, a device allowing for an error reading.

Title: Radio navigation instrument
Inventor: THOMASON ROY
IPC: G01S1/02
Filed: 1967-10-18
Abstract: 1,246,963. Radio navigation. R. THOMASON. 25 Oct., 1968 [18 Oct., 1967], No. 47528/67. Heading H4D. [Also in Division G1] A radio navigation instrument comprises a meter M whose movement drives a pointer 2 across the meter face 1, on which a mask 9 obscures at least most of the pointer when the input to the meter is zero, and a clamping circuit 16 from which the meter derives its input and which is fed with the radio navigation signal to be displayed, the circuit being effective to limit the minimum input to a level sufficient to allow the pointer to be displayed at the edge of the mask 9. As shown, the clamping circuit 16 limits the input between predetermined minimum and maximum values allowing the pointer to move between lower and upper positions 2c, 2d. The radio signals are monitored by means of rectifiers, level detectors 17 and AND gates 18 to provide the necessary D.C. supply to the clamping circuit 16 so that the absence of any signal removes the D.C. supply, the meter movement is de-energized and the pointer 2 disappears behind the mask, except for the small portion showing in a cut-out 9a. A similar "fail-safe" operation occurs if a reference voltage circuit fails. A second pointer 3 arranged at rightangles to the pointer 2 is driven by another meter with similar input and "fail-safe" arrangements. The meters provide a "fly to pointer" type of indication to a pilot in an aircraft. When used for VOR display only, the pointer 3 is not visible. A bearing indicator 5 is coupled to a course selector knob 4 and to a resolver which off-sets the meter display by the appropriate angle. An indication of the sense ("TO" or "FROM" the beacon) in which the aircraft is flying on the radio beam is provided in accordance with information from a radio compass. The two meters may drive the pointers 2, 3 in accordance with ILS localizer and glide path information respectively. The clamping circuit may be a linear integrated circuit or take the form of a potentiometer, Fig. 5, with a wiper arm W on a rotor 20 which (in response to phase difference in VOR signals) sweeps resistances R2, R3 joining arcuate conductors C1, C2 forming another rotor 19, preset according to a desired course by the knob 4. Higher accuracy can be obtained by replacing rotor 19 by two rotors (21, 22) Fig. 6 (not shown) of which one is geared to rotate five times faster than the other.

Title: Pulse code modulation encoder
IPC: H03M1/00
Filed: 1971-10-13
Abstract: 1373395 Analogue to digital converters PHILIPS ELECTRONIC & ASSOCIATED INDUSTRIES Ltd 13 Oct 1971 [15 Oct 1970] 47646/71 Heading G4H In a dual ramp analogue to digital converter the input analogue signal is integrated whilst binary weighted clock pulses are counted, the integration being stopped that the next clock pulse after the integrator voltage exceeds a threshold level, the integrator then being discharged to zero whilst equi-weighted clock pulses are counted. The first and second counts provide fine and coarse digital components of the analogue signal. Alternatively a non-linear integrator may be used in conjunction with equal spaced, instead of binary weighted, clock pulses. In Fig. 7 an analogue signal from a microphone 700 is sampled by brief closure of switch 702 and the sample is integrated in a Miller integrator 705-708, whilst binary weighted clock pulses are fed to counter 722 by a switch 723. After the integrator voltage reaches a threshold voltage plus Eh, of unit 709 or minus Eh of unit 711, signal C or C3 from the units by AND gate 726 at the next binary weighted clock pulse causes the integrator to integrate down to zero by opening switch 703 and closing switch 712 or 713 to supply positive or negative reference voltage to the integrator. During discharge of the integrator equi-spaced clock pulses tn are fed via switch 733 to a binary counter 732. The coarse and fine digital components are combined in a logic unit (not shown). The binary counter 732 may have an extra position LO so that if the threshold unit only responded some way past its proper threshold value causing the integrator to proceed to a timing instance one later than it should have, a longer period can be accommodated in counter 732 and a carry is added into the least significant position of the coarse digital component in counter 722.

Abstract: 1377111 Delta-modulation INTERNATIONAL BUSINESS MACHINES CORP 24 Oct 1972 [19 Nov 1971] 49069/72 Heading G4H A delta-modulation encoder is provided with a 4-bit shift register in the feed back loop thereof whereby the bits Nk, N k-1 , N k-2 , N k-3  are stored, Nk being the bit currently transmitted, the storage register thereby holding a 4-bit word which word is used to select firstly a value indicative of the delta step represented by bit Nk which is supplied to the integrator of the feed back loop, and secondly a value of a threshold with which an input is compared to determine the value of the output bit, these values -being worked out empirically but generally being of small magnitude when the word indicates the system is in an "idling state", i.e. the input signal is of near constant amplitude and of larger magnitude when the word consists of, e.g. mostly "1's", indicating that the value of the input is changing rapidly, the system being further provided with a shift register for storing binary coded values V k+3 , V k+2 , V k+1 , V k  of samples of the input signal from which a word indicative of the value is derived and used as input to the decoder. As shown, the means 22 is provided for deriving the values F(V) from where they are taken to a subtractor 24 where the difference is derived, the value A k-1  being derived from feed-back loop 20 using the bit stream of the previous  k-1  bits and is the total sum of all the incremented steps represented by the transinitted bits. This difference is taken to a comparator 32 where a bit Nk is derived which is "0" or "1" depending upon whether the difference is smaller or greater than a threshold value T. The transmitted bit is also applied to the shift register 28 and the 4-bit word contained therein is applied to a 4-bit-to-1 of 16 converter, not shown, where the 16 output lines form input lines to 2 diode matrices 30, 38 which supply the binary words indicative of the value D, the amount to be added to the integrated value in the summing circuit 26 and equal to the step size represented by N k , and the threshold value T. A receiver, not shown, comprises the same components as feed-back loop 20. The use of the register 28 and the variable step and threshold value devices ensures an absence of overshoot or hunting and provides variable increment encoding with only 1-bit per increment. The use of the device 22 ensures the encoder reacts promptly to changes in V to prevent phase lags in the decoded signal.
