Title: Improvements in or relating to Gas Analysis Apparatus
IPC: G01N21/37
Filed: 1968-07-10
Abstract: 1,188,626. Gas analysis. BERGWERKSVERBAND G.m.b.H. July 10, 1968 [July 27, 1967], No.32984/68. Heading G1B. Apparatus for the analysis of gas mixtures by measuring pressure variations in a gas mixture subject to periodically intermittent electro-magnetic radiation comprises a measuring chamber 7, and a comparison chamber 10 a porous wall area 8 in end-chamber through which the gas mixture to be analyzed can pass into the chambers from a duct 9, and a pressure metering device in the form of a membrane capacitor located so as to measure pressure changes between the two chambers 7, 10. The apparatus is described with reference to the determination of carbon monoxide in gas mixtures also containing carbon dioxide and methane, which mixture is fed into the duct 9, and leaves via a buffer space 17 and capillary 18. Radiation from an emitter 1 is passed alternately through the halves 4, 5 of a cell by the position of a rotating shutter disc 3 driven by a motor 2. The two radiation paths unite in a diffuser 6 and pass to the measuring vessel 7. The porous wall areas 8 are preferably of sintered metal and no radiation passes through the comparison cell 10. The half-cell 4 is filled with carbon monoxide and the half-cell 5 with nitrogen so that radiation lying within the absorption band of carbon monoxide will be absorbed in the cell 4, whereas the radiation passes unhindered through the cell 5. The diffuser 6 contains a mixture of methane and carbon dioxide but no carbon monoxide and this acts as a filter removing radiation lying within the bands of these constituents preventing interference with the carbon monoxide measurement in the cell 7. Pressure variations are produced in the cell 7 by the intermittent passage of radiation from the half cells 4, 5 and passages 11, 12 connecting with opposite of the membrane capacitor 13 which is formed as a differential capacitor with a membrane located between two electrodes and is connected to an amplifier and measuring instrument. Adjustable volumes 14, 15 serve to balance the time constants of the pneumatic systems on either side of the membrane.

Patent GB-942415-A (GB)
Title: Preparation of adipic and alkyladipic acids
IPC: C07C51/31
Filed: 1961-09-19
Abstract: Adipic or alkyladipic acids are made by oxidising with a molecular oxygen containing gas hexahydrobenzoic acid or an alkyl substituted hexayhdrobenzoic acid at 50-150 DEG C. in the liquid phase in the presence of a catalyst soluble in the reaction mixture which provides as the catalytically active constituent a simple cation of chromium, manganese, iron, cobalt, nickel or copper.  The catalyst may be added to the reaction mixture in the form of finely divided metal, as the metal oxide, hydroxide, carbonate or carboxylate. The preferred catalyst is cobalt, at 80 to 120 DEG C.  The oxidation mixture may contain as solvent an aliphatic or aromatic carboxylic acid, or their methyl or ethyl esters, especially acetic acid. Cyclohexanol and/or cyclohexanone are formed as by-products and can be recovered as such or re-circulated with the starting materials. Cyclohexyl acetate and the lower dicarboxylic acids may also be obtained as by-products. The reaction may be effected at atmospheric or supertmospheric pressure. Toluene or xylene may be used as the primary starting material for conversion to hexahydrobenzoic acids by side chain oxidation followed by catalytic ring reduction. Examples describe batchwise and continuous operation of the process and give details of the separation of the reaction products and methods of assay.

Title: Thermally responsive temperature regulating device
IPC: G05D23/275
Filed: 1938-11-18
Abstract: 521,599. Thermal switches. WILCOLATOR CO. Nov. 18, 1938, No. 33630. [Class 38 (v)] [Also in Group XXIX] A thermally operated electric switch or valve has setting means comprising a pointer and dial, behind one of which a lamp is placed to be visible therethrough, which lamp is operated upon operation of the switch or valve. In the two pole switch for controlling an oven as shown in Figs. 2 and 8, a rise in the temperature of a bulb 10 causes fluid pressure to compress a bellows 18 against a spring 26 and thereby to move to the right a stem 24 inside which is screwed one end of a rod 25 which has freedom of longitudinal but not of rotary movement relative to a rod 65 upon which a handle 83 is rigidly fixed. A spring 34 is in compression between the lower end of a lever 28 pivoted at its upper end, and the upper end of a spring 36 rigidly fixed at its lower end. Also carried at the upper end of spring 36 is an H-shaped member 44 of insulating material on which two contacts 47 are mounted pivotally for self alignment, which bridge pairs of contacts such as 52, 53. When a pointer 88 on the handle 83 points to the off position, a cam 93 on the handle pushes a rod 94 against a spring 97 which holds the member 44 in the open circuit position. Upon rotation of the handle 83 in a clockwise direction so that the pointer indicates the required temperature, the contacts are released and the rod 25 is screwed to the left against the spring 34 and whose lower end is moved across the line joining the two ends of the spring 36 and the switch closes with a snap action. As shown .in Fig. 9, this closes the circuit to a lamp 100, preferably a neon tube, in series with a high resistance 103, and a heating element 106. The temperature rises, the bellows 18 is compressed and the rod 25 and the lever 28 move back until the required temperature is reached when the switch opens with a snap action, and the heating circuit and the lamp are switched off. The lamp 100 which shines through a transparent or translucent dial 73 or a hole 75 therein thus indicates whether the switch is on or off. In a modification described, a fixed pointer co-operates with a dial which rotates with the handle. Specification 521,556 is referred to.
