Title: Device for correcting automatically for the temperature and the pressure of the gas, the indications of a recording calorimeter
IPC: G01N25/42
Filed: 1932-12-12
Abstract: 390,467. Gas calorimeters. COMPAGNIE POUR LA FABRICATION DES COMPTEURS ET MATERIEL D'USINES A GAZ, 12, Place des Etats-Unis, Montrouge, Seine, France. Dec. 12, 1932, No. 35182. Convention date, April 12. [Class 97 (iii).] Relates to apparatus for automatically correcting the indications of recording gas calorimeters for variations in temperature and pressure, so that the calorific value indicated is that of gas under the same temperature and pressure conditions as the gas the heating value of which is to be ascertained, viz. the gas passing through a gas works meter. A galvanometer G is provided with two windings. One winding E1 measures the calorific value of the gas, for example by means of thermo-electric couples D1, D2 in the inlet and outlet to the calorimeter K of the cooling fluid which may be supplied from a water meter J coupled to the meter I supplying gas to the burner B. The second winding E2 measures the difference between the temperature of gas passing at the gas works meter and the gas passing at the meter I by means of thermo-electric couples C1, C2 respectively and applies a temperature correction to the galvanometer indication. The pressure correction is applied by two liquid pressure gauges M1, M2, measuring the pressure at the gas works meter, for example by communicating with the inlet or outlet pipe A of the gas works meter (not shown). Each gauge has a branch forming a reservoir for liquid in which dips a counterweight balancing the bell of a pressure regulator. One regulator R1 is placed in the inlet and the other regulator R2 in the outlet of the meter I so that variations in pressure at the gas works meter may be transmitted to the meter I in the required ratio to correct the calorific value. The indications of the galvanometer G may be used with an integrating device to give the product of the volume measured at the gas works meter and the calorific value of the gas. Adjustable counterweights P1, P2 may be secured to the beams supporting the bells of the regulators.

Abstract: 1356423 Fuel injection systems SOC DES PROCEDES MODERNES D'INJECTION SOPROMI 28 July 1971 [24 Aug 1970] 35566/71 Heading G1N In an I. C. engine fuel injection control system, the duration of injection pulses provided by a circuit TC is regulated in dependence upon a voltage representing at least one operating parameter, the voltage function having a plurality of distinct sections of different slope. As shown, a circuit Vd transforms the inlet pressure sensed by gauge 21 into a linear voltage function which is transformed by a circuit P1 into a sectioned voltage function, and a circuit P2 transforms the linear voltage function of temperature (gauge 22 and circuit VT) into a sectioned voltage function which is modified by a linear voltage function of engine speed (pick-up I and circuits Vv and Ev), the outputs of circuits P1 and P2 being superposed to provide the injection regulating voltage. The circuits P1, P2, Fig. 2 (not shown), each include a number of transistors each having a different threshold of response to the linear input voltages of pressure and temperature respectively to thereby provide the sectioned voltage functions. The circuit TC includes a programme-controllable uni-junction transistor, which, when an injection starting pulse is applied to TC from the pick-up I, becomes blocked and remains blocked until a capacitor charges to a predetermined value of the regulating voltage from circuits P1, P2 applied to the gate of the uni-junction transistor, at which time the injection pulse provided by TC terminates. The modification provided by the engine speed may be effective only between two threshold values, and a circuit EC, responsive to the linear pressure voltage, may be effective to reduce the charging current to the capacitor in circuit TC, to thereby increase the duration of the injection pulses at full load conditions. In an alternative embodiment, Fig. 5 (not shown), the circuits P1, P2 are arranged to provided a voltage function having non-linear sections.

Title: Improvements in or relating to carbon elimination in jet engines
IPC: F02C7/30
Filed: 1953-12-22
Abstract: A hydrocarbon fuel for jet engines contains a compound of barium, cadmium or antimony.  During the combustion of the fuel in a jet engine, the presence of the metal compound inhibits the formation of carbon deposits in the engine and also results in the elimination of carbon deposits already present in the engine. Hydrocarbon - insoluble compounds of barium, cadmium or antimony, particulary oxides of these metals and barium carbonate, may be dispersed in the jet fuel.  Alternatively, hydrocarbon-soluble compounds of these metals, particularly such compounds as form oxides of the metals or barium carbonate in the combustion zone, may be dissolved in the jet fuel.  Suitable hydrocarbon-soluble compounds are the salts of naphthenic and aliphatic acids. Organometallic compounds of cadmium and antimony, barium salts of aliphatic monocarboxylic acids, aromatic acids and dialkyl phosphoric acids, and barium phenylates, are also mentioned.  The hydrocarbon jet fuel may boil in the range of about 100-600 DEG F. and may be a petroleum fraction.  The fuel composition may contain additional ingredients such as dispersing agents, ignition promoters ((e.g. amyl nitrate), oxidation inhibitors and corrosion inhibitors.  In an example, a hydrocarbon jet fuel contain cadmium or barium naphthenate.

Abstract: 970,532. Gyratory crushers. NORDBERG MANUFACTURING CO. Sept. 13, 1963, No. 36197/63. Heading B2A. A seal 48, located between spaced apart eccentric cylindrical surfaces 38, 36 provided on the crushing bowl 26 and the adjustment ring 14 or bowl support of a gyratory crusher, is arranged to work with the bowl during part of its up-and-down adjusting movement and remain attached to the bowl support during another part of the bowl adjusting movement. The flexible rubber or like sealing lips or rings 48 are held in position by upper and lower clamping rings 50, 52 bolted together, and levers 56 are mounted on top of the assembly 48, 50, 52 and circumferentially spaced around it. Each lever has locking portions 62, 64 on opposite front edges, which can fit in grooves 40, 42 just above the sealing surfaces 36, 38, so as to connect the assembly to the ring 14 or the bowl 26. The rear of each lever 56 includes an upstanding cam 66 whose surface can mate with and contact slanted surfaces 44, 46 on the ring and bowl, so as to rotate the levers 56 about their pivotal mountings 54 and move the locking portions 62, 64 on the levers out of contact with the grooves 40, 42. In operation, when the bowl 26 is in its upper position the seal is connected to the ring 14 by the locking portions 62 which are positioned in the groove 40. As the bowl moves downwards to compensate for wear to the bowl liner, the seal remains fixed to the adjustment ring 14, until, about midway of the bowl's travel, the surface 46 on the bowl strikes the cams 66 on the levers to release them, so that the locking portions 62 move out of the groove 40 and the locking portions 64 move into the groove 42, and the sealing assembly becomes connected to the bowl. When the bowl is in its lowest position, i.e. when the liner requires renewal, it is raised, so that at the midway position the levers rotate and the seal ring is again locked with the adjustment ring.
