Title: Apparatus for determining the calorific value of flowing fuels
IPC: G01N25/42
Filed: 1938-06-01
Abstract: 503,164. Calorimeters. JUNKERS KALORIMETERBAU GES. June 1, 1938, No. 16358. Convention date, June 25, 1937. [Class 97 (iii)] Automatically adjusted nozzles modify the supply of fuel and cooling medium to a calorimeter so that the calorific value of the fuel indicated corresponds to a normal state. As shown cooling water from the storage tank 1, having a recooling member 34, is passed by a conveyer belt 3 to a tank 57 with an overflow 58. From the tank 57 the water flows through pipe 54, inlet thermometer 44, calorimeter, and outlet thermometer 45 to a discharge box 46 and by way of a two-way diverting member 43 either to a pipe 41 and a measuring vessel for checking purposes or to a pipe 36, safety device 14, and the tank 1. The amount of water passing to the calorimeter is modified by providing a bye-pass 32 leading to a nozzle 28, which is automatically adjusted by a needle 30 on an arm 33 pivoted at 33a and connected by a link 13 to a resilient diaphragm 12. The latter responds to changes in volume of a body of gas 11 which is surrounded by, and subject to the temperature of, the fuel. The fuel is led to the burner 37 through a pressure regulator 5, a moistening apparatus 7, the chamber 27 containing the temperature responsive device 11, 12, and the density regulator 24, comprising a needle valve 23 controlled by a spring loaded diaphragm. A gas meter 6 or flow meter 35 may be included for checking purposes. Air for combustion is saturated in the shaft 10 before passing through the pipe 4 to the burner 37. The weighted lever 21 of a fuel valve 22 is held in the open position by the stem 15 of a float in the safety device 14. A spring urged pin 17 is held in the retracted position by the diaphragm 19 when gas in a chamber 38 is heated by the flame. Insufficiency of fuel causes the diaphragm to release the pin 17 which moves to push a resilient catch 16 on the lever 21 clear of the stem 15 so that the lever 21 falls and the valve 22 closes. The thermometers 44, 45, comprise resilient bellows surrounded by a sealed body of gas and connected respectively to the main wheels of a differential gear, of which the planet wheel frame carries the pointer 50 moving over the scale 53. The pointer 50 may also carry a recording pen 51 and a contact moving over a potentiometer 49.
Patent GB-984522-A (GB)
Title: Superpolyesters
IPC: H01B3/42
Filed: 1961-05-05
Abstract: A soluble, fusible, linear polyester with intrinsic viscosity of at least 0.5 is formed of four structural units-(1) 25-45% of p-phenylene, (2) 5-25% of o- or m-phenylene, or o,o1-biphenylene, (3) 20-45% of isophthalate, and (4) 5-30% of terephthalate, the sum of (1) and (2) being 1-1.05 times that of (3) and (4), and the sum of (1) and (4) being no greater than 70% of the total.  The polymers may be prepared from the appropriate dihydric phenols and aromatic dicarbonyl halides in certain solvents (Specification 984,523) or by the ester-interchange one or two-stage process in the same solvents. The solvents are benzophenone, m-terphenyl, chlorinated or brominated biphenyls, chlorinated or brominated diphenyl oxides, chlorinated or brominated naphthalenes.  All four reactants may be reacted at once or one or more acid materials may be reacted with one or more dihydric phenols and the other reactants added later, or two separate polyesters may be prepared and then co-condensed. Minor amounts of monohydric phenols or monoboric acid halides may be added as chain-stoppers. Suitable chain-stoppers are phenol, cresols, xylenols, ethylphenol, p-hydroxy-phenylbenzoate, benzoyl chloride, bromide, or iodide, toluoyl chloride, naphthoyl chloride, biphenylcarbonyl chloride, or when free hydroxyl groups are desired in the polymer, hydroquinone, or resorcinol.  Example (1) describes preparation of random copolymers by simultaneous reaction, in mixed monochlorobiphenyls, of mixtures of hydroquinone, o,o1-dihydroxybiphenyl, iso-phthalyl chloride and terephthalyl chloride; (2) is similar, the two phenols and isophthalyl chloride being first reacted together, and the intermediate reacted with terephthalyl chloride; (3) is similar to (1), using hydroquinone and resorcinol as the two phenols, and mixed trichlorobiphenyls as reaction medium; (4) prepares intermediates from resorcinol and terephthalyl chloride in mixed trichlorobiphenyls, and continues the reactions after addition of hydroquinone and isophthalyl chloride; (5) prepares poly - p - phenylene - m - phenylene isophthalate terephthalate copolymers using different combinations of three of the appropriate reactants in the first stage and the fourth reactant in the second stage.  The products may be shaped, e.g. to fibres or films which may be transparent, by pressing or casting.  They are useful for coating or impregnating compositions, e.g. as wire enamels, for electrical insulation, or as adhesives, e.g. for laminates.  Specification 984,521 also is referred to.
