Title: Method and means for photometrically evaluating light-absorbing zones in a thin layer of light-scattering material
IPC: G01N30/95
Filed: 1971-09-20
Abstract: 1328734 Photo-electric evaluation of thinlayer media CARL ZEISS-STIFTUNG (trading as CARL ZEISS) 20 Sept 1971 [30 Sept 1970j 43700/71 Heading G1A In the photo-electric evaluation of thin-layer media e.g. as used in chromatography, both reflectivity and transmissivity measurements are carried out simultaneously in such a way as to obtain measurements of the absorption due to the separated sample free from errors due to variations in the light scattering characteristics of the material of the thin-layer medium (the separating layer) itself, which occur when reflectivity measurements alone are used. In apparatus for reading a chromatogram, Fig.4, the plate 6 is fed through the beam of light from monochromotor 4, which irradiates the plate at normal incidence. The outputs of detectors 7, 8 monitoring diffusely reflected light and transmitted light respectively, are amplified (9 and 10) and summed at 11. The recorder 12 is controlled in synchronism with respective movement of the plate 6 and the optical system. Particular optical arrangements are described. In one, Fig.5 (not shown), integrating spheres with associated detectors are mounted on either side of the plate 6. In another, Fig. 6 (not shown) one fibre optic bundle leads light to the plate surface and two more lead reflected and transmitted light respectively, to respective detectors. The fibre optic arrangement can be modified so that a single detector can be used to sum the transmitted and reflected intensities, the end of the bundle conducting the transmitted intensity being combined at a common location with that conducting the reflected intensity.

Abstract: 1,134,437. Feeding webs. W. H. BRADY CO. 11 Oct., 1966 [14 Oct., 1965, No. 45320/66. Heading B6B. [Also in Divisions G1, G2 and H4] An object is positioned relative to a probe sensing a marking on the object, the probe comprising at least one pair of fibre optic bundles having first ends spaced in the direction of relative movement of the object and second ends co-operating with photocells and the difference between the outputs of the photo-cells being used as error signal in a servo circuit controlling the relative position. Printed labels P, Fig. 1, on an aluminium strip W are positioned relative to punch dies Dm, Df by diamond shaped eyemarks 10. The probe 30 comprises five fibre optic bundles. Bundle 32 which is coupled to a light source 54 for illuminating the eyemark terminates as a circular area at the probe tip, and is there surrounded by the fibre optic bundles 34, 36, 38, 40 in the form of annular quadrants. At the probe tip the bundles are separated by and encased in epoxy resin. The bundles 34, 36 spaced along the strip W are coupled to photoresistors 56, 58 and the difference in output thereof is derived by potentiometer 64 and fed through a contrast adjusting potentiometer 66 and an operational amplifier 67 to a chopper 74 which produces a corresponding A.C. error signal to control the strip feed motor 16. The bundles 38, 40 spaced across the strip W similarly control a transverse adjusting motor 20. Feedback from the tachogenerators 70, 170 prevents hunting. When both error signals are zero the punch is operated and then the motor is connected to a counter to move the strip so that the next eyemark is in the vicinity of the probe. In a modification the optic fibres coupled to light source 54 may be mingled with the bundles 34, 36, 38, 40.

Abstract: 1,089,219. Automatic temperature control systems. K P. E. CONTROLS. Oct. 29, 1965 [Nov. 6, 1964], No.45381/64. Heading G3R. Also in Division H3] In a system for maintaining constant the temperature of an electrically heated body, the A. C. power supply to the heater is controlled by varying the on/off periods of solid state control means, e.g. silicon controlled rectifiers, power being supplied in complete half-cycles of the A. C. source. A signal representative of temperature is obtained from a bridge circuit including a temperature sensitive resistor (not shown) and is applied at terminals 13, 14 to the circuit of Fig. 2 in which transistors 15, 16, 27, 28 form a balanced, low-drift, high gain, D.C. coupled amplifier providing a balanced error signal output at terminals 31, 32, the temperature setting being adjustable by a potentiometer 20 forming part of a series circuit 19.. 22 in parallel with a Zener diode 18 which, with resistor 17 and stabilized smoothed D. C. supply 5, 8, provides a reference voltage at terminal 14. The error signal from terminals 31, 32 is applied to similar terminals of a switching oscillator shown in Fig. in which transistors 36, 37 form an emitter-coupled differential amplifier and control the mark/space ratio of a variable mark/space ratio oscillator constituted by transistors 40, 41, which oscillator frequency is determined by a capacitor 39 and is less than the frequency of the A. C. power supply to the heater. The output 46 of the oscillator is applied to a similar terminal of the circuit of Fig. 4 wherein a transistor 49 switches the primary winding of a transformer 51 whose secondary windings 52, 55 supply the trigger circuits of the silicon controlled rectifiers. Transistor 49 is controlled by a transistor 47 switched "on" and "off" with a mark/space ratio determined by the oscillator of Fig. 3, and is additionally coupled through a capacitor 58 to an unsmoothed terminal 9 of the stabilized D. C. supply, Fig. 1 (not shown), so that transistor 49 can only be switched on when the potential at 9 is rising in the positive direction, thereby ensuring that the controlled rectifiers are fired at the start of a half cycle of the A. C. supply. After each charging stroke from terminal 9, the capacitor 58 is discharged by a diode 50.

A signal E, Fig. 2, is obtained from the thermal conductivity cell 11, Fig. 1, of gas chromatography apparatus, and by means of a ball-and-disc device 17 and a chopper disc 16 the signal is converted to a train of pulses, the frequency of which depends on the amplitude of the signal E. The pulse train is recorded on a magnetic tape 28 which is played back after the complete sample has passed through cell 11. A start pulse recorded on tape 28 triggers a timing circuit 42 which produces regularly-spaced pulses defining successive intervals V1, V2 ... In each interval a number of pulses, depending on the amplitude of the signal, is registered in counter 41 and is transferred to a register 47 at the end of each interval before being finally supplied to a computer 49. The computer 49 is programmed to detect deviations of the signal E from the base amplitude B and to accumulate the numbers registered in the successive intervals during which the deviation occurred, at the same time allowing for drift of the base amplitude B so as to compute the true area enclosed by the lines B, E. Allowance is also made to obtain true areas in cases where two peaks E overlap. Provision may aso be made, Fig. 6 (not shown), for charging the range of measurement automatically by selecting one of two sets of holes in the chopper disc.

Abstract: 1368523 Reciprocating pumps L J CARLYLE 4 Oct 1972 [5 Oct 1971] 45784/72 Heading F1A [Also in Division B1] Apparatus for dosing a primary liquid flow with metered quantities of an additive comprises a transparent cylindrical housing 2 having a piston 13 with a coaxial passage 15 therethrough closed by a bottom closure member 20 carried on a stem 21 passing through the passage 15. A cage 22 is bolted to the bottom of the piston 13 and carries a plunger 24 which in the position of the piston shown in Fig. 1 is entered into a cylinder 34 formed in a plug 32. Primary liquid enters at 10 and carries the piston 13, closure member 20 and cage 22 together up the cylinder 2, forcing liquid ahead of them out of an outlet (11), Fig.2 (not shown) in the cap 3; additive is drawn through the valve 40 into the cylinder 34 as the plunger 24 rises. At the top of the cylinder 2 the spring 29 strikes the cap 3 causing the member 20 to separate from the bottom of the piston 13 and open the passage 15; the piston 13, member 20 and cage 22 then sink to the bottom where the plunger 24 re-enters the cylinder 34 forcing the contents thereof past the valve 39 Fig. 9 into the cylinder 2. The legs 30 strike the bottom cap 4 causing the closure member 20 to rise and again close the passage 15, and the cycle recommences. The quantity of additive pumped on each cycle may be altered by adjusting the plug 32 along the screw 33. With increase in the rate of flow of the main liquid, the proportion of additive will tend to deminish since while the movable parts are descending in the cylinder 2, there is unobstructed flow between the inlet 10 and outlet (11) through the passage 15. In modifications the member 20 may be a flap hinged to the piston 13; a spring may be used to cause the moving parts to descend instead of relying on gravity (see Fig. 10, not shown); the piston 13 may be replaced by a flexible diaphragm Fig.11 (not shown); the additive pumping plunger may be fixed and the cylinder form part of the cage 22 Fig. 12 (not shown); the valve 39 may be located in the plug 32 Fig. 13 (not shown); the piston may have a plurality of narrow passages to delay its descent Fig. 14 (not shown); the closure member may lie on top of the piston 13 Fig. 17 (not shown); or the passage 15 and closure member 20 may be replaced by a fixed tube (96), Fig. 18 (not shown) having a flap valve (93) actuated by a striker pin (110) on the piston. The apparatus may be used to introduce a bloat control agent into animal drinking water, in fertilizer and weed control systems, and for mixing oil and petrol.
