Title: Improvements in or relating to calculating or indicating apparatus
IPC: G06G1/14
Filed: 1931-11-18
Abstract: 380,646. Calculating-apparatus; indicating apparatus ; speedometers. ENGBLOM, J. F. T., Villa Tomoana, Elm Avenue, and WILMAN, C. W., 7, Grange Avenue, both in Beeston, Nottingham. Nov. 18, 1931, No. 31947. [Classes 106 (i), 106 (iii), and 106 (iv).] The resultant of two quantities is indicated by the juxtaposition of two flexible bands bearing graphs of the respective quantities and moved proportionately to their values. The invention is described as applied to the determination of average speeds, one band being displaced proportionately to distance and the other to time. As shown in Fig. 1, the band B2 wound from roller R3 to roller R4 at a rate proportional to distance bears a number of curves formed by joining logarithmic scale graduations on lines transverse to the length of the band. The other band B1 has a single similarly plotted curve and is driven by a clock. The bands pass through a common slot formed by spaced guides G1, G2 and the single time curve indicates at the line of contact the particular speed curve to be read. In modifications the bands may be superposed one being transparent, or one may be translucent and the lower opaque except for a transparent time curve trace, a lamp below causing a line of light to traverse the upper band and to indicate the speed at a transverse slot. The bands may be driven at variable rates to allow for increasing diameter of the rolls or to enable the curves to be used for a second range of readings. Thus, referring to Fig. 6, the endless bands B5, B6 are driven by sprocket wheels SW1, SW2 the drive of which can be reduced to one-tenth after the first hundred units of distance or time, this being accomplished by electric contacts EC1 or EC2 and cam M1 or M2 rotated from the respective sprocket wheels. In a further construction, Fig. 7, the bands B5, B6 are driven by ratchet mechanism such as RW1, DP1 from corresponding electromagnets EM1 energized intermittently by the vehicle and by the clock. The bands may be reset by external buttons rotatable by hand so as to disengage the ratchet pawls to permit the bands to return under spring action.

Title: Explosion gas turbine plant and method for operating the same
IPC: F02C5/12
Filed: 1952-12-19
Abstract: 759,840. Gas turbine plant. SCHILLING ESTATE CO. Dec. 19, 1952 [Dec. 24, 1951], No. 32269/52. Class 110(3) A gas turbine plant comprising a plurality of explosive chambers feeding a turbine comprising a number of stages has the counter pressure at the rear of a stage lowered during the period of expansion of the gases in the stage so that the heat drop across the stage during expansion of the gases is uniform. In the arrangement shown, a number of explosive chambers, of which two 27, 28 are shown in section, supply combustion gases to a turbine having two stages 25, 26. The explosive chambers are connected to the turbine by conduits 29, 30, 41, 42 and 45, 46 controlled by valves 31, 32, 37, 38 and 43, 44. The operation of these valves in the various explosion chambers are time-displaced with respect to each other so that when the gases from one chamber are being expanded in the nozzles I, gases at a lower pressure from another chamber are being, fed to the chambers 39, 40 and gases from a third chamber are being fed to the discharge housing 47. The gases from the third chamber may be the residual gases forced out of the explosion chamber by the charging air. The turbine nozzles, the explosion chambers, the chambers 39, 40 and the housing 47 are so designed that the expansion lines on the Q-V diaphragm are automatically parallel. Q is the enthalpy of the gases in kcal/nm<SP>3</SP> and V the pecentage volume of the combustion gases discharged in relation to the total volume of combustion gases generated in each explosion chamber. The gases leaving the turbine may be used either in a useful power turbine or used for chemical or physical purposes. The power of the turbine shown may be used to drive a compressor supplying air to the explosion chambers and to drive auxiliaries. In a modification, the gases from the chamber 47 are passed through an additional turbine stage before leaving the plant. In one arrangement of this modification, the' additional turbine stage only utilizes the gases from the explosion chamber and has an exhaust chamber common with the stage 26. In a second arrangement, both the exhaust gases from the stage 26 and the gases from the explosion chamber pass through the additional stage to the exhaust. In a further modification the counter pressure is lowered by a piston mechanism connected to the counter pressure spaces. Specifications 288,321, 288,322 [both in Class 110(iii)], 315,366 [Class 51(i)], 410,049 759,841, 759,842, 759,844, 759,845 and 759,846 are referred to.

Abstract: 918,756. Bearings. AMERICAN METAL PRODUCTS CO. Sept. 25, 1959 [Oct. 3, 1958], No. 32630/59. Drawings to Specification. Class 12 (1). [Also in Groups XXV and XXVI] Low friction bearing material in the form of liquid, particles, or particles dispersed in liquid is deposited on the surface of a bearing member and is solidified to form a layer, and a layer of backing material is applied over the low friction layer in firm and immovable relation therewith to retain the low friction layer in intimate engagement with the surface of the bearing member. The bearing member may be of spherical, cylindrical, arched, flat or other surface configuration and the invention may be applied to bearings and seals. The low-friction material, which can be applied by brushing, spraying or dipping, may be an aqueous dispersion containing 59-61% by weight of polytetrafluoroethylene (P.T.F.E.) and 5.5-6.5% of a non-ionic wetting-agent from which the water can be driven off by gentle heating, after which temperatures of approximately 680- 750 F. may be employed to sinter the particles of P.T.F.E. to form a solid coating. Alternatively, the P.T.F.E. layer can be toughened at about 450‹ F. Nylon may also be used in the form of a water-isopropyl alcohol dispersion containing 20% by weight of nylon, 60% of water and 20% of isopropyl alcohol from which the solvents can be driven off by gentle heating and the nylon then sintered at between 325 ‹ and 400‹ F. A solution of polyethylene obtained by heating 15 parts by weight of " Dylan 6600 " and 35 parts of tetra- or deca-hydronaphthalene at about 350‹ F. for five minutes may also be employed, this solution being applied to the bearing member and allowed to cool until it gels, after which it is heated gently at about 270‹ F. to drive off the solvent. Various polyhalocarbon solutions or dispersions may also be used. The backing material may be injection or compression moulded around the low friction layer or may be applied as a preformed rubber member, any suitable hardenable thermosetting or thermoplastic material or phenolic impregnated glass fibrous material being used If thermosetting material is employed it can be preformed and partially cured to the " B " stage before being applied to the low friction layer. If injection moulding techniques are used the low friction layer may be thickened in the region of the point at which the backing material strikes the layer. A thin coating of varnish may be applied to the low friction layer to help prevent the penetration of the backing material.
