[Also in Division G1] On emerging from a liquid chromatograph column, the separated components of a liquid sample, in a stream of carrier liquid, pass through a streaming potential detector (Fig. 4), whose output (Fig. 10, not shown) identifies the components and the quantities present. The detector comprises a tube 9 of glass, P.T.F.E. or polyester resin with gold or platinum electrodes 10, 11 and possibly a packing 14 of granular or preferably fibrous glass, P.T.F.E. or polypropylene, the fibres being orientated as shown. Due to relative movement of charges in the moving liquid and opposite charges stationary on the tube wall, a potential appears between electrodes 10, 11 which is amplified and recorded (12, 13). The carrier liquid (water or ethyl alcohol) is supplied to the chromatography column (Fig. 3, not shown) at constant pressure (by a pump, a high level reservoir or by applying a constant gas pressure to the liquid in a closed vessel), and the sample is injected into the top of the column. A constant streaming potential is developed, depending on the flow rate of the carrier liquid through the detector, and as the separated components arrive they are indicated as sudden variations in potential (Fig. 10). KCl, NaCl, KI, Na 2 CO 3  KMnO 4 , RbCl, and sodium acetate aqueous solutions may be detected with water as a carrier, while in detecting benzene, toluene, benzaldehyde, acetone or acetic acid solutions in ethyl alcohol, ethyl alcohol is used as a carrier.

Abstract: 1,083,395. Photoconductive scanning devices. INTERNATIONAL BUSINESS MACHINES CORPORATION. Aug. 24, 1965 [Sept. 2, 1964], No. 36218/65. Heading H1K. A device for detecting the position of a beam of radiation consists of a pair of strip-shaped semi-conductor zones forming a PN junction with a third zone overlying and forming a PN junction with the upper of the zones and extending laterally on one or both sides of it. Alternatively the middle zone is replaced by a plurality of separate zones distributed along the length of the first zone. The embodiment shown in Fig. 3, which is of this type, has strip electrode 24 on one edge of the third zone and contacts 70, 72 at the ends of the first zone. Series of square voltage pulses of decreasing amplitude but constant duration are supplied to contacts 24, 26 by generator 28, and ramp voltage pulses interlaced with these pulses are superimposed on a fixed bias voltage applied along the first zone. Each square pulse drives minority carriers generated by light incident at a given point a distance in the Y direction proportional to the pulse amplitude. Consequently after a given pulse minority carrier will lie adjacent one of the P zones 12 if light is incident at a distance therefrom corresponding to the distance travelled in the Y direction by such carriers. The ramp voltage then applied between contacts 70, 72 progressively reverse biases the junctions between zone 14 and zone 12 and the accumulated minority carriers give an output pulse across load 34 at the instant when the junction they lie adjacent becomes back-biased. Thus the instant during the ramp pulse when the output pulse occurs indicates the X co-ordinate of the light beam and the square pulse after which it occurs the Y co-ordinate.
