Title: Automatic compensation of baseline drift
IPC: G01N30/86
Filed: 1969-12-12
Abstract: 1298685 Base line drift correction BODENSEEWERK PERKIN-ELMER & CO GmbH 12 Dec 1969 [14 Dec 1968] 60795/69 Heading G4H A circuit for correcting base line drift (used with a gas chromatograph or ionization detector) measures the drift between observed peaks and corrects it by applying a signal of opposite polarity to the input. The input Ue is fed into a Miller integrator 24, the output from which passes through two threshold devices K 1  and K 2 , set to operate if the signal is more positive or more negative than a certain value. From the threshold devices the signal passes to AND gates 34, 36, the other input 38 to the AND gates is controlled by the presence or absence of a peak at the input, so that the AND gates are switched off when a peak signal appears at the input. The AND gates 42, 40 have inputs from clock pulse generator 44 and AND gates 36, 34, the outputs leading to a bidirectional counter 50. If the input between peaks is not zero, clock pulses are counted in the forward or reverse direction by the counter. The output of the counter controls a D to A converter comprising voltage input Vk, transistor switches 52, 54, 56, 58, 60, and precision weighted resistors 62, 64, 66, 68, 70. The output of the D to A converter is fed to the input of the Miller integrator so as to oppose a non-zero signal. Thus a feedback loop is established which in equilibrium maintains the base line, i.e. the input signal between peaks at zero. When a peak appears at the input, the correction signal is determined by the value stored in counter 50 just prior to AND gates 36, 34 switching off. Voltage Vv is used to obtain a reading on the counter and hence operation of the feed back loop when there is zero base line drift. In another embodiment a binary decimal counter is employed and the polarity of the reference signal fed to the D to A converter is switched by a pair of relays according to the input polarity of the base line drift. In a third embodiment the D to A converter is of the potentiometer type.

Patent GB-740798-A (GB)
Abstract: 740,798. Periodic-counter speed indicators. LANDIS & GYR AKT.-GES. Dec. 18, 1953 [Dec. 19, 1952], No. 35367/53. Class 106 (3). A maximum demand meter has a synchronous motor serving as a timing element and a device for the temporary disconnection of the maximum demand indicator, such disconnection occurring only at the end of the registration period during which a control switch outside the meter is opened. The meter (not shown) drives a'pinion 6, Fig. 1, which normally drives a gear 7 against a spring 8. The gear 7 drives the maximum demand indicator. The spindle of the pinion 6 is carried by one end of a pivoted lever 11 the other end of which has a follower 12 which rides the surface of a cam disc 2 driven by a synchronous motor 1. When, at the end of a registering period the follower 12 enters the groove 3 the pinion 6 is withdrawn from the gear 7 which is returned by the spring 8. At the same time an insulated member 15 carried by the lever 11 opens a switch 14 parallel with a main switch 16 in the circuit to the synchronous motor 1. If the main switch 16 is opened the synchronous motor will therefore continue until the gears 6, 7 are separated and the member 15 opens the switch 14. In another arrangement the switch 14 is replaced by a change-over switch.

Apparatus for printing and simultaneously indicating clock time comprises a second type wheel 1 driven in steps by a chronometer 19 through a feeding magnet 21 and driving in its turn minute and hour type wheels 2, 3, an indicator 6, 7, 8 for seconds, minutes and hours coupled to the time type wheels, hand re-adjusting mechanism 15, 16, 17 for the time type wheels and indicators, at least one number type wheel 4 advanced one step after actuation of a key 31, a recording strip 37 which moves entirely inside'the apparatus and on which the data registered on all the type wheels 1, 2, 3, 4 is printed on actuation of the key 31 and which is then advanced one step and a second record 39 which is printed simultaneously with the recording strip 37 and can be removed from the apparatus. When the key 31 is ,depressed, levers 42, 43 raise a pressure plate - 41 to press an inserted card 39 and transparent paper strip 37, with ink ribbon 40 inked both sides therebetween, against time type wheels 1, 2, 3 and number type wheels 4, 5 to print the time and number registered thereon. Upon release of the key 31 its return movement causes three sets of pawl and ratchet means 45, 46 to advance the paper 37, say 12 mm., 51, 52 to advance the ink ribbon and 30, 29 to advance the type wheel 4 so that together with wheel 5 it registers the number of recordings. Wheels 4, 5 each carry the series of cyphers 00 to 99, wheel 4 driving wheel 5 through transfer mechanism. Wheel 3 carries the cypher 01 to 12 five times and wheels 1, 2 each carry the cyphers 00 to 59. The apparatus may be designed so that when a card 39 ruled in columns and rows, Fig. 3, is inserted with its broad edge leading the columns will register with appropriate type wheels, while the row in which they print will be determined by the setting of a mask 54 slidable over the slot 38 and secured by screw and slot 59, 58. In place of the card mechanism, the duplicate record may be made on another strip which can be drawn out of the apparatus and torn off for use as a receipt. The same source of second pulses may be used to supply further similar recording-apparatus and also electric clocks. The arrangements for hand setting the type wheels may be inside.the casing so that adjustment can only be made by, authorized persons when the cover is removed. The key 31 may be actuated manually or electrically through a relay controlled through a photo-electric cell.
