Title: Analytical technique and process control for determining the  concentration of cations in a solution
IPC: G01N21/31
Filed: 1974-10-14
Abstract: 1474466 Determining the concentration of cations in solution IMPERIAL CHEMICAL INDUSTRIES Ltd 8 Sept 1975 [14 Oct 1974] 44407/74 Heading G1A In an apparatus for determining the concentration of a plurality of types of cations, positively charged ions, in a solution 11, the unknown liquid is directed via a manifold 12 and a rebulizer 9 into a flame 8. Radiation from four lamps I each coated with one of the metals whose concentration in the solution is to be determined, and emitting a characteristic wavelength, is combined into a single beam 2 by mirrors 3 and lenses 4. The resulting beam is directed via the flame 8 and is received by a mono-chromator 23. The monochromator contains a photo-multiplier 24 and is set to one of the appropriate analyzing wavelengths. The flame is produced by a burner 7 equipped with ignitors 6 and fed by streams of nitrous oxide and acetylene. To enable calibration the manifold 12 is also supplied with four streams 10 of standard solutions of four mixtures of salts of the metals whose concentration in the process stream are to be determined. The whole apparatus may be computer controlled to analyze the process stream for four metals at pre-selected intervals.

A physical quantity C, e.g. the amount of fuel supplied to an I.C. engine, is regulated as a function of two physical variables A, B, e.g. rotational speed and angular position, the variables A, B causing movement of an electrically conducting member 8, having a portion presenting electrical or electromagnetic properties which vary from point to point on its surface, in two respective directions relative to an electrically conducting tracer member 17 resting on the surface of member 8. As shown, variations in the rotational speed of a shaft 6 cause the member 8 to take up different axial positions on the shaft 6 due to the centripetal force on balls 4, and movement of a lever 11 causes the member 8 to rotate relative to the shaft 6. The member 8 has a portion of constant thickness which is composed of two layers of material having different electrical characteristics, the surface of separation of the two layers varying in distance from the surface from point to point.

Abstract: 993,022. Clock systems. ELEKTROCAS NARODNI PODNIK. Dec. 20,1961 [Dec. 21,1960; Feb. 16,1961], No. 45709/61. Drawings to Specification. Heading G3T. A system of master and subsidiary clocks is periodically corrected by a wireless time signal composed of a combination of impulses. The correction means is associated with signal analysing means which responds to a time correction signal and detector means determines the character and extent of the master clock deviation so that the master clock temporarily drives the subsidiary clocks slower or faster until they are corrected. In one example the master clock is driven by a synchronous motor and correction is effected by changing the rate of impulses from the master clock to the subsidiary clocks, the master clock itself being corrected by a heart shaped cam mechanism. The signal analyser includes a pawl and ratchet mechanism driven by the impulses. In another example an auxiliary synchronous motor regulates the speed of the main synchronous motor driving the master clock and a generator picks up the speed of the main synchronous motor and drives the synchronous motors of the subsidiary clocks.

Abstract: 1,015,223. Electrostatic recording. OMNITRONICS Inc. Nov. 20, 1963 [Dec. 3, 1962] No. 45892/63. Heading G5R. An electrostatic printer includes a printing head 33, Fig. 1, which is an improvement of the head described in Specification 981,760, comprising a number of groups of electrodes 212, 213, Fig. 8, extending across the width of a record tape 20, each group having two pairs of electrodes, to produce a single charged area. The charged areas form a latent image representing a code, are inked at 23, Fig. 1, and fixed at a pressure station 24 before being wound on to a take-up reel 25. Head construction.-The electrodes 212, 213 are supported in blocks of insulating material 203, 204, Fig. 6, separated by a quartz insulator 205 and extend to the bottom of the printing head 23 where a mask 209 with apertures 207 may be secured by clips 188. Inside the head 23 the electrodes are connected to resistors which may be changed to give differing electostatic images. The other side of the resistors terminate in plugs 200, Fig. 10, connected to an incoming data source or pulse control 35. If the mask 209 is fitted it may be electrically unconnected or connected to a D.C. bias. The tape is held against the head by a displaceable pressure finger 195, Fig. 7. Tape feed, Fig. 1. The tape 20 is continuously or incrementally fed from the printing station 22 by a drive capstan 32 when a pinch-roller 31 is electromagnetically pivoted towards or away from it (circuit, Fig. 2, not shown). At this stage a further pair of drive rollers 52, 53 in the pressure fixing station 24 are not operating, so that a loop of the tape which is guided round a roller 36 on a compliance arm 37 grows in length. After the loop has grown a predetermined amount, electrical contacts associated with the position of the compliance arm 37 close to operate pinch-roller 52, and release a brake 59 associated with capstan 53. The speed of feed by rollers 52, 53 is 10% higher than that of rollers 31, 32 so that the length of the loop diminishes and the compliance arm 37 swings to the right. The contacts associated with the drive to rollers 52, 53 and the brake 59 are changed back to their original positions to stop the feed. To halt movement of the tap through the system a stop switch is operated and a brake unit 27 is electrically operated and drive roller 31 is displaced away from the tape. The compliance arm 37, due to movement of the tape, moves to the right and the contacts operating rollers 52, 53 and associated brake 59 also stop. If the drive rollers 31, 32 are operating and drive rollers 52, 53 are quiescent a beater 45 in the inking station 23 is moved out of range of the tape.
