Title: Improvements in or relating to indicator tubes
IPC: G01N31/22
Filed: 1968-06-20
Abstract: 1,210,295. Gas analysis. AUERGESELLSCHAFT G.m.b.H. June 20, 1968 [June 29, 1967], No.29541/68. Heading G1B. An indicator tube for indicating the presence of a particular gas in the air by means of an indicator substance which changes colour on reaction with the gas, is provided with a zone arranged in front of the indicator substance in the direction of flow of air through the tube, the zone containing a material which also reacts with the gas preferably without appreciable colour change, but which material differs in colour from the indicator substance after reaction, this arrangement preventing the indicator substance from changing colour until sufficient of the gas has passed through to react with the material in the zone. In this way the tube may, act as a dosimeter for the particular gas. A further substance e.g. carbon may be disposed in front of the other substances to absorb any disturbing foreign substances. Thus in a tube for indicating the presence of carbon monoxide, the material in the zone may be silica gel impregnated with iodine pentoxide and forming sulphuric acid together with chromic acid or cobalt sulphate. This material will remain a brown colour during reaction with carbon monoxide. The indicator substance may be silica gel impregnated with iodine pentoxide and forming sulphuric acid which will change from colourless to green. In a tube for indicating the presence of hydrogen sulphide the material in the zone may be silica gel impregnated with an aqueous solution of zinc acetate, and this will remain white in colour. The indicator substance may be silica gel impregnated with a salt of a heavy metal which forms a coloured sulphide.

Title: Process for the separation of the component parts of alloys or mixtures of metals
IPC: C22B7/00
Filed: 1938-10-12
Abstract: 508,925. Extracting metals from mixtures and alloys. KEMP, P. Oct. 12, 1938, No. 29593. Convention date, Oct. 25, 1937. [Class 82 (i)] In a process of separating the constituents of metallic mixtures and alloys by liquation, the liquid portion is separated from the solid residue by forcing the mass under a pressure of at least 500 atmospheres against a member pervious to the liquid portion. The pressure may be obtained by means of a compressed gas or a mechanical press. In the press shown, the melted. alloy is placed in the receiver 1, which may be heated by a burner 6, and after cooling to liquation temperature is forced by the piston 4 through a perforated member 2 into a container 5. Alternatively, the alloy may be introduced in the solid state, or allowed to solidify in the receiver, in which it is subsequently heated to liquation temperature. In some cases, especially when the alloy contains only a small proportion of the component which is solid during liquation, a preliminary separation by known liquation methods may be employed, the residue being then further separated by the present method under high pressure. Fractional separation of an alloy of several metals may be carried out by subjecting the liquid component of a first separation to a further separation at a lower temperature, or the solid component to one at a higher temperature. The separation may be facilitated by the addition of a metal or alloy which combines with certain of the alloy constituents to form a liquation component. For example, silver may be extracted from lead by adding zinc, and antimony from lead or tin alloys by adding aluminium. The process may be applied to the production of white or speculum metal from tin alloys containing lead and copper ; the extraction of tin and lead from zinc alloys ; the separation of lead alloys into type metal and a residue of high antimony content; and the extraction of tin and antimony from scrap lead. Examples are given of the treatment of alloys containing tin, antimony, copper and lead, and of tin, antimony and lead.

Title: Improvements in or relating to the braking of relative movements between two adjacent bodies
IPC: F16F7/02
Filed: 1927-11-07
Abstract: 281,627. Compagnie d'Applications MÚcaniques. Dec. 2, 1926, [Convention date]. Clutches, friction.- In apparatus for braking frictionally the movements in one or both directions occurring between two rela. tively movable bodies, two frictional devices having different coefficients of friction act on the moving bodies in order to obtain different braking actions for the same value of the pressure exerted between the rubbing surfaces. The invention may be applied to clutches. Fig. 1 shows diagrammatically two bodies 1, 2 movable relatively in the directions of the arrows f1, f2 or oppositely thereto. The bodies 1, 2 may be of material having different coefficients of friction with respect to the interposed material 3 which is gripped between the bodies 1, 2 by the force P. A projection 4 on the body having the lower coefficient, of friction works in a larger groove 5 in the material 3. The first part of the relative movement of the bodies 1, 2 is thus opposed by the smaller resistance due to the friction between 2 and 3, while further movement is opposed by the greater resistance due to the friction between 1 and 2. the projection 4 then engaging one of the ends of the groove 5. Spring buffers may be arranged at the ends of the slot to cushion the blow of the projection 4. The interposed member may be composed of two layers having different coefficients of friction and united to one another directly or by means of a metal plate which is also adapted to contact with the projection 4.

Title: Improvements in high frequency signalling systems
IPC: H03H2/00
Filed: 1924-12-11
Abstract: 248,838. Western Electric Co., Ltd., (Western Electric Co., Inc.). Dec. 11, 1924. Thermionic generators; modulating systems and harmonics, absorbing.-In a high frequency transmission system, more particularly for use as a radio transmitting circuit, a tuned circuit TC is interposed between the power amplifier circuit PA and the antenna or load circuit A in order to suppress the transfer of harmonics to the antenna or load circuit. The circuit TC and antenna circuit A are both tuned to the fundamental frequency. The circuit TC is made up of two parallel branches, one of which includes a variable condenser 4 in series with an adjustable inductance 3 and the other of which includes a capacity 5 having a lower impedance than the first mentioned branch to the higher frequencies. The condenser 4 is also included in the antenna circuit, which comprises, in addition, the tuning coil 6 and aerial 7, so that the condenser 4 serves as a common coupling element for transferring energy from the power amplifier output circuit to the antenna. In order to secure ordinarily loose coupling, the capacity of the coupling condenser 4 is made large relatively to the other capacity 5. The modulating system, comprising the transmitter 1, voice frequency amplifier VA, and amplifier OA, is similar to that described in Specifications 133,366 and 152,811, whilst the source 2 and its circuit for supplying high frequency carrier waves to the amplifier OA is preferably of the kind disclosed in Specification 141,046. Space current is supplied from the source 8 to the amplifiers VA, OA in common through the choke coil. The amplified speech waves from the amplifier VA act to modulate the waves supplied from the source 2 in the amplifier circuit OA and the resulting modulated waves are impressed on the grids of the power amplifier system P.A., which is of the type in which the tubes are worked beyond the straight portion of their characteristics during at least one half cycle of the waves impressed in the inputs thereof.

Inventor: SIER CHARLES
IPC: G01N33/20
Filed: 1960-08-31
Abstract: <PICT:0931605/III/1> The content of a gas in a metal is determined by introducing an inert gas into an enclosed atmosphere, introducing the metal specimen thereinto, heating the specimen to evolve the gas and determining the composition of the resultant gas mixture.  As shown in the Figure a preferred apparatus comprises a vertical refractory tube 1 surrounded by furnace 8, a Katharometer 2, a chamber 5 sealed by a removable plug 6 and having retractable pin 7 for introduction of the specimen into the tube 1 and an inlet 9 and outlet 11 for the inert gas.  In operation, the apparatus is flushed with an inert gas, e.g. argon or nitrogen supplied through a drying chamber 13 and valve 10.  When the Katharometer 2 gives a steady reading, plug 6 is removed and a metal specimen e.g. steel is inserted into chamber 5 thus resting on pin 7.  After a few moments valve 12 is closed and inert gas flushes out any air from chamber 5 which has been introduced.  Plug 6 is reinserted, valve 10 closed and pin 7 withdrawn causing the specimen to fall into the heated zone.  Gas, e.g. hydrogen is evolved and a thermal convection current produces a uniform concentration of hydrogen in the gas system, which may be estimated by Katharometer 2. Applications specified are control of manufacture of steel and measurement of the rate of evolution of gas from a metal.
