Abstract: 1,057,197. Measuring and controlling temperature electrically. O BRAUN and B. BRAUN, [trading as B. BRAUN]. May 20, 1964 [July 18, 1963], No. 20783/64. Heading G1N. [Also in Division G3] A mercury thermometer 1 Fig. 1 (not shown), contains a slidable contact element 2 mounted on a nut 4 which travels on a threaded spindle 3, rotated by means of a motor 7; and the two conditions of a relay 8 cause the motor to drive the element respectively up or down, to follow movements of the mercury column 10 so that a pen 14 makes a record of the movement of the element on a chart 15. The relay 8 may be operated by the element 2 touching the mercury column 10, so that the element 2 and therefore the pen 14 follows the variations in length of the mercury. The drive is transmitted via a magnet 5 and disc 6 mounted at the end of the spindle 3. The device may be used to regulate the heating of a liquid 20, by replacing the record chart 15 with a programme chart Fig. 2 (not shown) in which one portion 18 is conductive, and the other portion 17 is insulating. A departure of the pickup 16 from the boundary line causes a second relay 21 to operate a heater 19 and so to raise the mercury column 10 and the element 2, and to drive the pickup carrier 12 further up its threaded spindle 11, until the pickup is again on the line. In an alternative arrangement Fig. 3, (not shown) the relay 8 is operated by the programme chart and the pickup 16 to maintain the pickup on the boundary line, at the same time causing the contact 2 to move correspondingly; and the relay 21, controlling the heating, is operated by the contact 2 and the mercury column 10, so that the liquid is heated (or allowed to cool) until the top of the mercury column reaches the height of the element 2.

Title: Gas chromatography method
IPC: G01N30/50
Filed: 1959-06-18
Abstract: In the separation of gases by gas chromatography employing a solid adsorbent, said adsorbent is contacted prior to or during chromatographic separation with a suitably selected loading gas whereby "tailing" of the time-concentration curve of one or more of the effluent components is minimised.  The loading gas has an affinity for the adsorbent greater than that of the desired component or components of the sample gas: it may comprise a single gas or a gas mixture comprising an effective component. The loading gas may have a boiling point-critical temperature range similar to that of the desired component or components.  The adsorbent may be contacted with the loading gas prior to or after being placed in the column; where the loading is performed during chromatographic separation the loading gas may be added to the carrier gas continuously or intermittently.  Specified combinations of sample gas, adsorbent and loading gas are respectively (a) C2-C5 hydrocarbons, silica gel and dichlorodifluoromethane, (b) a "liquid petroleum gas" (ethane, propane, propylene and/or butane) alumina and a mixture of nitrogen and water vapour (the former being the carrier gas), (c) a mixture of aromatic hydrocarbons, activated charcoal and steam and (d) butane-containing sample, alumina and dichlorodifluoromethane or methyl chloride.  It is considered that the loading gas is sorbed as such or as a pseudo gas or pseudo liquid in the pores of the adsorbent or in the interstices between the particles thereof and that these sites are thereby made unavailable to the "lagging" molecules of desired components which otherwise produce "tailing" effects.
