IPC: C06F1/12
Abstract: 454,879. Match-making machines. BADISCHE MASCHINENFABRIK & EISENGIESSEREI VORM. G. SEBOLD UND SEBOLD & NEFF, 3, Seboldstrasse, Durlach, Baden, Germany. April 27, 1935, No. 12639. Convention date, May 31, 1934. [Class 50] Matches ejected from a match - making machine are collected on a separate loose bottom 12<1> for each collecting box 12, the bottoms being supported on a common cross-beam 60 and progressively lowered by two rack-bars 59, and after the required pile has collected a third rack-bar 71 is caused to lower the piles at an accelerated rate into the boxes which are then automatically rocked over for removal. Meanwhile fresh bottoms have been automatically pushed under the ejection device. A pawl 37<1> is initially lifted causing a counterweight suspended from a lever 33 to displace a slide 34 carrying one row of bottoms from a magazine 54 towards the match bars 4. The operator then disengages a locking pawl 69 from a ratchet wheel 66 and by means of a hand wheel rotates a shaft 57 and toothed wheels 58 in mesh with rack-bars 59 to raise the cross-beam 60 underneath the slide 34, which is then retracted by movement of lever 33. In the uppermost position of a third rack 71 which is also raised by movement of shaft 57, a stop 7111 rocks a lever 73 to free a feed pawl 67 thereby causing the feed ratchet 66 to rotate through the agency of a lever 65 and eccentric 64 keyed to the main shaft 2. As the cross-beam 60 slowly descends, the operator suspends the collecting boxes from a frame 8 which he rocks inwards before the bottom-supporting brackets have reached an intermediate position 60<11>. The cross-beam continues to descend until position 60<111> is reached whereupon a tongue 74<11> of a cam member 74 pivoted to the rack 71 engages the bevelled lug of a slide 78 and draws it to the left, Fig. 2, to allow a toothed wheel 82 carried by a sliding block 79 to engage with the rack. The wheel 82 is in mesh with a continuously rotating wheel 83 which effects thereby an accelerated lowering of the cross-beam. As this occurs the cam 74<1> strikes a roller 39 thus disengaging the pawl 37<1> and allowing'fresh bottoms to be pushed below the ejection device. At the bottom position of the cross-beam an upper stop 71<1> on the rack strikes lever 73 so as to free the ratchet 66 from the feed pawl 67 and the beam rocks a lever 91, a rack 88 thereby being brought into engagement with a toothed wheel 86 on the same shaft as wheel 83. A lever 87 attached to the rack accordingly rocks the box frame 8 backwards to a position determined by the end of the toothed portion of the rack. Meanwhile pawls 23 on the frame have struck stops 26 and released tappets 13<1> on two members 13 disposed on a hollow shaft 14 so as to allow a weight 17 to return a rear wall 16 back against a stop 95.

Abstract: 1431478 Titration system CORNING GLASS WORKS 4 Oct 1973 [4 Oct 1972] 46415/73 Heading G1B A titration system comprises a delivery apparatus for delivering precise volumes of titrant to a mixture, a sensor for sensing an effect or reaction in the mixture on the addition of titrant, an end-point detector, and an indicator for displaying the volume of titrant required to reach said given effect; a clockpulse generator for producing a series of clockpulses; a pulse gate responsive to control signals from said end-point detectors for gating said clockpulses; automatic calibration apparatus including a pulse counter for dividing the gated clockpulses by a number related to an expected nominal number of aliquots required to titrate a standard mixture, and for producing a number of titration pulses; a pulse ratio circuit responsive to the gated clockpulses and the titration pulses for producing output pulses related by a specified calibrating ratio (being the expected nominal number of aliquots of titrant required to calibrate the standard mixture divided by the actual number of aliquots of titrant required to calibrate the standard mixture) to the number of pulses received; and a digital display device responsive to said output pulses for indicating the precise volume of titrant added to said mixture multiplied by said calibrating ratio. The titration system is shown in Fig. 1. Mixture to be titrated is contained in vessel 11 which is provided with a sensor 12 to detect the appropriate physical parameter, e.g. pH. The electrical signal generated in sensor 12 is passed to amplifier 13 and compared with an end-point level in detector 14 which controls the opening and closing of gate 15. This gate allows pulses from oscillator 16 to pass to the automatic calibration system until the end-point is detected. The gate is then closed. The calibration system 17 produces two pulse trains of frequencies f 1  and f 2 . The train of frequency f 1  is applied to the titrant delivery system which includes a stepping motor 18 which is driven a very specific angular rotation for each pulse applied thereto. This angular rotation ultimately results in the syringe 20 dispensing a specific volume of titrant for each pulse. The pulse train of frequency f 2  indicates on digital display 21 the amount of titrant added. In operation, a standard solution is placed in vessel 11 and the system accordingly. calibrated. An unknown sample is then placed in vessel 11 and titrated.

Filed: 1971-10-15
Abstract: 1369432 Digital differential analysers NATIONAL RESEARCH DEVELOPMENT CORP 15 Oct 1971 [15 Oct 1970] 49079/70 Heading G4A An apparatus provides digital output signals representing increments of the product of a variable (integral scaling) ratio and the integral of a dependent' variable and includes means adapted to process signals representing increments of a dependent variable to provide integrand signals representing increments of the integral of the dependent variable, a first register adapted to accumulate, the integrand signals, a second register adapted to store a number related to the desired variable ratio, and means providing a digital output signal each time the change in the contents of the first register bears a predetermined relationship (e.g. equal) to the contents of the second register. Each cycle of operation is initiated on receipt of an increment dx of an independent variable x which may be time, the dx signals being clock pulses. In operation register 16 is loaded with the integral scaling ratio and half this ratio is entered in register 13 where it is modified by adding or subtracting respectively the contents of register 16 if the initial value of the contents of register 11 (i.e. the integrand y) are negative or positive. Between successive (clock) pulses dx several dy increments may be accumulated in register 10. When a clock pulse occurs adder 12 updates the contents of register 11 by adding the contents of registers 10 and 11 and storing the result in register 11. Register 13 is then updated by adding the contents of registers 11 and 13 and storing the result in register 13. If the contents of register 13 pass through zero a dz output is generated by circuit 18, the dz output, which also indicates the direction of passage through zero, causing the contents of registers 13 and 16 to be added and stored in register 13 together with an appropriate sign bit to ensure that the signs of the contents of registers 11 and 13 are opposite. If the sign of y changes during integration select circuits 14 and 15 modify the contents of register 13 by adding a number of a magnitude equal to the number in register 16 but of a sign opposite that of the new integrand y. The first time register 13 passes through zero is ignored due to the initial conditions. The circuit 18 may include a comparator for comparing the contents of register 13 and 16. In this case register 13 initially contains zero, each output from the comparator causing the contents of register 16 to be subtracted from those of register 13. It is stated that at each dx pulse half the contents of register 10 may be used in addition to the updated contents of register 11 to update register 13 to provide for trapezoidal integration.
