Title: Improvements in or relating to gas analysing apparatus
IPC: G01N7/08
Filed: 1921-04-19
Abstract: 162,249. Svenska Aktiebolaget Mono.. April 23, 1920, [Convention date]. Gas analysis.-Apparatus for carrying out two or more series of analyses in which the several records are represented on a common chart by lines spaced close together and extending from the same zero line as described in Specification 157,895, is arranged so that in both series at least one constituent of the gas is always included. For example, in one series the percentageof carbon dioxide is determined, and in the other series the total percentage of carbon dioxide, carbonic oxide, hydrocarbon, and hydrogen; and by arranging the records in this manner a third record is readily given, namely, the differences be tween these two records, that is, the percentage of carbonic oxide, hydrocarbon, and hydrogen. As shown, the first measuring-vessel h is connected to an oscillating vessel g containing liquid and which according to the position of the vessel seals one or other of the pipes h, i, in the manner described in Specification 138,355; the sample therefore passes alternately to the absorber k when the percentage of carbon dioxide is to be determined, and to the oxidizing-furnace l and then to the absorber k for recording the percentage of carbon dioxide, carbonic oxide, hydrocarbon, and hydrogen. Specification 103,812 is referred to.

Title: Improvements in or relating to instruments for dividing or measuring lengths
IPC: G01B3/02
Filed: 1948-04-26
Abstract: 635,521. Graduated spirals. STUTCHBURY, C. P. April 26, 1948, No. 11401. [Class 106 (ii)] [Also in Group XX] An instrument for measuring lengths comprises a body or frame having a plurality of spiral slots or edges therein or thereon which radiate from the centre or axis of the body or frame and are equally spaced apart along a line passing through that centre or axis, and is provided with marking means which, in association with the slots or edges, enable selected points defined by the slots or edges to be marked positively on a surface on which the instrument is being used. As applied to the instrument described in Specification 628,490, wherein a disc is provided with a plurality of spiral slots the marking means are formed by upturning the edges of the spiral slots so that they have a sharp edge for marking the surface used. The diametral pointer used in conjunction with the disc to select the required spacing on the spirals may have a tapered cross-section to facilitate bringing a greater pressure over the desired parts of the sharp upturned slot edges for marking purposes. Alternatively the disc may have a plurality of spiral grooves in its under-surface the edges of these grooves being relatively sharp to provide the marking means. As shown in the Figure, the invention is applied to a body 21 of conical shape having a plurality of spiral slots 24 extending around its surface, the slots being equally spaced apart along any straight line joining the apex 25 and the base 26. The marking means are constituted by the pointed ends 30 of rods 29 mounted in a straight slot 28 in an inner cone 22. The rods are maintained in a rigid position at right-angles to a straight line from the apex 25 to the base 25 by means of a bar 23 rigidly secured at one end to the base of the inner cone 22 and pivotally secured at its other end to the apex 25 of the outer cone so that as cones 21, 22 are rotated with respect to each other the bar slides round the surface of the outer cone 21 and the rods move round the spiral slots. In another embodiment a conical shaped body is provided with a plurality of spiral ribs around its surface, the edges of the ribs being relatively sharp to serve as marking means, a pointer mounted on the apex of the cone co-operating with a further pointer movably mounted on its base defining the straight line to be divided. The disc or cones may be provided with scales showing the spacing apart of the spirals and the disc may be provided with an angular scale of degrees.

Abstract: 850,574. Programme distribution systems. COMPAGNIE GENERALE DE TELEGRAPHIE SANS FILS. April 6, 1959 [April 24, 1958], No. 11567/59. Class 40 (4). [Also in Group XL (c)] In a transistor amplifier comprising preliminary stages 1, 2, 3 and a push-pull output stage 4, 5, variation in the output caused by variation in the load due to changing the number of loudspeakers connected is compensated by means of a negative feed-back path of variable attenuation. This negative feed-back path comprises D.C. blocking condenser 10, a current-limiting resistor 9 and thermistors 6, 7 and 8 of which thermistor 8 is little affected by changes in the output voltage, its purpose being to compensate for variations in the ambient temperature. A change in the number of speakers beyond that with which the variable feed-back can deal is compensated by additional feed-back in the stage 3, a de-coupling condenser 14 shunting the emitter circuit resistor 15 being disconnected by relay 13. Each loud-speaker speech coil 17 has connected in series with it a resistor 16 through which direct current passes to the energizing coil of the relay 13, so that the relay is energized when more than a certain number of speakers are in circuit. A resistor 18 provides a limiting value for the loading across the output transformer. The base biasing circuit of the output transistors 4, 5 comprises a potentiometer 19, 20 of which 19 is a thermistor.

Abstract: 1,203,581. Chromium tripolyphosphate; ion exchange separation of alkali metals. D. BETTERIDGE and G. N. STRADLING. 29 Aug., 1967 [31 Aug., 1966; 14 March, 1967], Nos. 38960/66 and 11987/67. Heading C1A. A chromium tripolyphosphate glass particularly one having a P : Cr mole ratio of approximately 2.5 : 1 has an infra-red spectrum which exhibits no well defined peaks, is free when in the acid form from stoichiometric proportions of metal ions other than chromium, is highly resistant to HCl, HNO 3  and H 2 SO 4  at ambient temperatures, is slowly soluble at ambient temperature in 0À1 M NaOH and exhibits selective ion-exchange activity for alkali metal ions in the presence of di- or polyvalent cations, e.g. Ni (II), Co (II), Mn (II), Cd (II), Zn (II), Ca (II), Sr (II), Mg (II), Fe (III), Cr (III), Cr (VI), Pb (II), In (III), Bi (III), Th (IV), Sn (IV), Ti (IV) and V (III). Ion-exchange material of the above composition can be prepared by reacting sodium tripolyphosphate and chromic chloride in aqueous solution at room temperature, separating the reaction product and allowing it to stand to form a green glass, preferably at 25‹ to 30‹ C. If relatively concentrated aqueous solutions of reactants are used the product is granular and can be used to pack columns after grinding, but dilute solutions yield less granular products which are suitable for thin layer or paper chromatography. The ion-exchange material is preferably used in the acid form. It can also be used with some of the protons replaced by Na<SP>+</SP>, K<SP>+</SP>, NH4+ and other cations. The ions Cs<SP>+</SP>, Rb<SP>+</SP>, K+ and Na<SP>+</SP> can be mutually separated by carefully eluting with HCI, NH 4 Cl, HNO 3 , H 2 SO 4 , or mixtures of the first two with suitable organic solvents. In this way the isotopes Cs 137, Rb 86, K 42 and Na 24 can be separated using 1 M HCl as eluant.
