Title: Improvements in, or relating to, liquid-fuel injection pumps for use in connection with diesel-type internal combustion engines
IPC: F02M59/46
Filed: 1933-06-14
Abstract: 421,285. Fuel -injection pumps for internal-combustion engines. PILGRIMS WAY MOTOR CO., Ltd., GRAVENOR, J., and ARMITAGE, E. L., Weydon Hill, Farnham, Surrey. June 14, 1933, Nos. 16927/33, 31915/33, and 6272/34. [Class 102 (i)] Fuel-injection pumps for Diesel and like engines are provided between the working chamber and the pipe line with a non-displacement two-way valve which on each relief of the injection pressure permits the return transfer of fuel from the pipe line for reducing the pressure therein and preventing drip at the injection nozzle and then closes. A valve f is disposed in a casing c and when seated on the plate d shuts off the working chamber a of the pump from the pipe line. Flats f<1> on the valve provide fuel passages f<3> through which, and holes e<1> in a spring pressed plate e, fuel is delivered to the pipe line. When the spill port of the pump opens and the working pressure drops, fuel returns from the pipe line through the passages f<8> to the pump a until the valve reseats itself. A spring g keeps the valve closed when the pump is not working and prevents drainage from the pipe line. A head may be formed on the valve body and to seat on top of the block d. In a modification, the main delivery valve i contains with its body portion i<1> a separate anti-dribble valve i f having a seating f<10> therein.

Title: Improvements in or relating to the production of ceramic dielectrics
IPC: C04B33/02
Filed: 1938-06-08
Abstract: 515,633. Electric condensers ; dielectrics. STEATITE & PORCELAIN PRODUCTS, Ltd., and CLARK, N. O. June 8, 1938, No. 17029. [Class 37] [Also in Group V] For obtaining ceramic dielectrics for electric condensers which will have zero firing coefficients (i.e., the temperature coefficient of dielectric constant is independent of the temperature of firing), mixtures of refractory substances with titanium oxide as base, containing substances of positive and negative firing coefficients are made. Steatite is an example of the former class and clay of the latter. By firing mixtures of zero firing coefficient and positive and negative temperature coefficient of dielectric constant, ceramics having both coefficients equal to zero may be obtained. An example of a mix is in titanium dioxide 28.0 per cent., witherite 5.0 per cent., steatite 27.5 per cent and clay 39-5 per cent. Magnesia and alkaline earth metal may also be added.

Abstract: 403,391. Raising oil &c. BROWN, N. F., Covandale, Woodside Walk, Hamilton, Lanarkshire. June 18, 1932, No. 17291. [Class 102 (ii).] In apparatus for raising oil &c. from wells the oil enters a chamber B past a valve B<6>, the seating of which is elevated in order to protect the valve from sand. The valve is enclosed in a perforated casing B' and is protected by a deflector A<4>. Compressed gas, intermittently supplied to the chamber B through a tube C, forces the oil through a pipe E to a gas separator F. The tube C is connected by a pipe C<1> to a valve casing D, for alternately connecting the tube to a high-pressure pipe D<1> through an inlet valve I<1> and to a low-pressure pipe D<2> through an exhaust valve I<4>. The latter is normally held open and in contact with the valve I<1> by a spring I<3> and the valve I<1> is normally held closed by the gas pressure on a piston I<2>. When pressure gas is admitted above a piston I, the valve I<1> is opened and the valve I<4> is closed. After the valve I<1> is closed the gas is used expansively until the pressure falls sufficiently to permit the spring I<3> to open the valve I<4>. The pressure gas is distributed to the piston I by a pilot valve operated by an intermittently energized electro-magnet H.

IPC: C03B18/18
Filed: 1965-04-23
Abstract: <PICT:1109392/C1/1> In the manufacture of flat glass, a layer of molten material is maintained on the surface of the molten metal between the edges of the glass and the side walls of the container, the density and surface tension of the material being such that it contacts only the edges of the glass and wets the walls of the container.  The molten glass emerging from the furnace discharges on to a bath of molten metal 15 and passes between divergent walls 20a, 20b into the tank 16.  Beyond the ends of the walls 20a, 20b conduits 32a, 32b discharge a molten material on to the surface of the metal. Graphite nose blocks 34a and 34b and 35a and 35b prevent sticking of the glass to the walls 20a and 20b and 22a and 22b respectively. The material is preferably an alkali metal salt, e.g. sodium molybdate. It is stated that the thickness of the layer of molten material determines the thickness of the glass sheet.

Title: Improvements in or relating to cyclic process for producing and recovering ammonia and hydrogen chloride from ammonium chloride
IPC: C01B7/05
Filed: 1954-06-16
Abstract: In a cyclic process for producing ammonia and hydrochloric acid from ammonium chloride by adding ammonium chloride to a melt of a bisulphate in a mixing zone, successively circulating the melt through hydrochloric acid and ammonia stripping zones, recovering hydrochloric acid and ammonia respectively from the vapour stream from the hydrochloric acid and ammonia stripping zones, and returning the stripped melt to the mixing zone, a small amount of phosphoric acid or a soluble inorganic phosphate is added to the circulating melt to precipitate metal impurities, e.g. iron, as phosphate.  The concentration of phosphate ion in the melt should be maintained at 0.1 - 10 per cent. and the phosphate or acid may be added intermittently or continuously at any point in the cycle.  The preciptated phosphates may be separated by filtering or settling from a sidestream of melt, which is then returned to the cycle.  The process and apparatus described are those of Specification 716,754, wherein ammonium chloride is mixed with an alkali metal or ammonium bisulphate melt in amount 0.15-0.75 moles per mole, and the melt is circulated through a hydrogen chloride stripper at 220-270 DEG C., and then through an ammonia stripper at 330-380 DEG C.  Suitable phosphates are ammonium dihydrogen phosphate, diammonium hydrogen phosphate, disodium hydogen phosphate, and sodium pyrophosphate. Reference is also made to the addition of thermally stable fluid organic media, e.g. trichlorobenzene, for heat transfer, to the melt and to the addition of the ammonium chloride to the melt by slurrying the salt in such a medium.
