Abstract: 1489092 Opposed piston IC engines;  reciprocating compressors ENERGIAGAZDALKODASI INTEZET 2 Dec 1974 52092/74 Headings F1B and F1N [Also in Division F2]  A reciprocating free-piston internal combustion engine comprises two pairs of opposed cylinders 48, 50, the pistons 40, 42 in each pair being yieldingly connected by means 60, 62 to a common piston rod 58 drivingly connected to a power output shaft 32 normal to the cylinder axis 36 via a transmission for converting the reciprocating motion into uni-directional rotation of shaft 32. In the arrangement shown, the transmission comprises a piston rod rack 58a engaging a toothed annulus 56 having a cammed inner surface 56a between which and shaft 32 are disposed rollers 106 to form a freewheel. Thus rightwards movement of pistonrod 58 causes the transmission to lock to apply a clockwise driving torque to shaft 32 whereas a freewheeling action occurs on the leftwards return stroke of the rod. The engine shown is of twostroke internal combustion type and includes opposed charging air pistons 84, 86 yieldingly connected to a common piston-rod 92 by diaphragms 94, 96. Piston-rod 92 engages toothed annulus 56 so that its reciprocating movement is maintained in opposite phase to that of piston-rod 58. Fuel is injected into the cylinders 48, 50 by pumps 64, 66 operated by levers 68, 70 having rollers 72, 74 engaging a piston-rod cam surface 58b. The second pair of opposed power pistons Fig. 2 (not shown) is disposed in further cylinders alongside the first pair, the respective piston rod 58, (108) engaging a common pinion 110 so as to maintain the desired opposite phase relationship. The additional pistonrod (108) also engages output shaft 32 via a free wheel transmission. In a modification Fig. 5 (not shown) the compression ratio of the engine can be manually or automatically varied by a screw and nut device (236, 238, 240) which can displace both the charging and power cylinders inwards or outwards relative to output shaft 32. In a modified four-stroke engine Figs. 3,4 (not shown) the rack and pinion part of the power transmission from each piston-rod is replaced by a pair of steel bands (130, 132) each fixed at one end to an extremity of the piston rod and at the other end to the outer annulus (56) of the free-wheel. A similar arrangement of bands (146, 148) is employed for the synchronizing connection between the two power piston-rods (58, 108).

Title: Surface Area Measurement of Standard Length Sample of Finely Divided Solids.
IPC: G01N15/08
Filed: 1967-11-22
Abstract: 1,164,359. Measuring total surface area of particulate materials; measuring porosity by gamma-rays. FULLER CO. Nov. 22, 1967 [Nov.29, 1966], No.53211/67. Headings G1A and G1N. In the determination of the total surface area or particle size of a finely divided material, e.g. concrete, by measuring the resistance to gas flow of a sample of fixed shape, volume and porosity or density, which is indicative of the particle size or total surfaces area of the sample particles, the required sample is prepared by compacting a portion of the material while measuring its density the compacting being stopped when the portion reaches the required density. A preset volume of this portion is then used as the sample. The density of the compacted portion of the material may be measured capacitatively, the dielectric constant of the material being indicative of its density. Alternatively it may be measured by transmitting gamma radiation through the mass and measuring the amount of radiation transmitted e.g. by an ionization chamber. As shown, a portion of the material is fed into a tube 18, Fig.1, of dielectric material, provided at its lower end with a perforate plate, through which the material cannot flow but gas can, the tube being connected at this end to a gas inlet 32. The tube is vibrated by a pneumatic vibrator 42 to compact the material. Alternatively mechanical compression or pulses of compressed air may be used for this purpose. Capacitor plates 44, mounted round the tube, whose capacitance is indicative of the density of the material, are connected to the output of an oscillator (122, Fig.3 not shown), and via an amplifier (126) to a comparator, where the signal from the capacitor is compared with a reference signal. When the two signals are equal, indicating that the required density has been reached, a relay (128) is energized, and the vibrator is de-energized. A member 48 is then moved across the upper end of the tube to separate off a fixed volume of the compacted material and provide a connection at the upper end of the sample via vent 60 to the at atmosphere, a perforate plate 58 containing the sample within the tube during the subsequent test. A constant pressure of gas is then applied to the lower end of the column of compacted sample and its rate of flow, indicative of the surface area of the sample, is measured, e.g. by a heat transfer transducer (114, Fig.2 not shown), and indicated and/or recorded on meter (120). The recorded signal may also be used for controlling the process producing the material, e.g. the grinding of cement, to keep the surface area constant.

Abstract: 1451224 Extractive distillation METALLGESELLSCHAFT AG 21 Nov 1973 [9 Dec 1972] 54116/73 Heading C5E In extractive distillation processes in which a hydrocarbon mixture to be separated is introduced at an intermediate level into a distillation column having heating means at the bottom, the necessity to reflux distillate is reduced or eliminated by introducing the selective solvent into the column in two or more streams at different locations above the level at which the hydrocarbon mixture is introduced, with the temperature of the stream of the solvent entering at the upper or uppermost location being lower than that of the remaining stream or streams of the solvent. In the example a stream 17, consisting of a benzene boiling range fraction which has been distilled from a hydrogenated coke oven or pyrolysis benzene, is introduced into the column 1 at 60‹ C. and extractively distilled with hot and cold streams 8 and 9 of recycled N-methyl pyrollidone at 120‹ and 60‹ C. respectively and a portion of the overhead is returned as reflux 10 between the points of introduction of the streams 8 and 9; the relative rates of flow of the hot and cold streams 8 and 9 and the amount of the reflux 10 are controlled by reference to the composition of the distillate. Fig. 1 (not shown) illustrates an extractive distillation in which the reflux enters the column above the points of introduction of the hot and cold streams of solvent. Fig. 3 (not shown) illustrates a process in which the solvent enters the column as three streams and no overhead is refluxed.
