IPC: C10B7/02
Filed: 1928-09-26
Abstract: 321,283. Marks, Sir G. C., (Chemische- Technische Ges.). Sept. 26, 1928. Retorts. - In the distillation of coal or lignite in chambers separated by hollow or solid heating partitions, the coal is continuously forced in a horizontal direction through the chambers which are subdivided by grids, and which are only a fraction of their height in length. As shown in Figs. 1 and 2, distillation chambers c alternate with heating chambers b traversed by hot gases, and the material is forced through the distilling chambers c which are subdivided by plates p, by a rotating drum c which is mounted eccentrically on an axis m. The coke is removed from the lower part of a surrounding chamber k and the distillates escape through holes i in the outer shell a. In Fig. 4, heating plates b<1> separate the charges in two sets of rotating chambers c which are so arranged that the charge falling between these sets is forced through the distillation chambers, the coke falling into the interior spaces k. A pusher e<1>, Fig. 5, may be used to force the coal through the distillation chambers c to the coke chamber k, grid plates p being used to divide the chambers c horizontally.

Title: Device for detecting damage to rotators
IPC: G01H1/00
Filed: 1975-07-10
Abstract: 1514792 Vibration measurement NIPPON SEIKO KK 10 July 1975 27659/77 Divided out of 1514791 Heading G1G For detecting damage in a rotator, e.g. a ballbearing, the cyclically-varying vibration produced as it is rotated is converted to an electrical signal which is applied to a peak detector the D.C. output level of which is periodically reset to zero. A bandpass filter extracts an A.C. component of the varying peak detector output level, which component is indicative of the degree of damage. In the described embodiment the amplified output 1 of a vibration pick-up (microphone) is filtered to remove low frequency components. The filtered signal 2, after AGC amplification, is passed to the peak detector, Fig. 3, (not shown) which is reset to zero at least once in each cycle of variation of the vibration. The peak detector output 4 is band-pass filtered to give A.C. signal 5 indicative of damage. Signal 5 drives a meter, or is rectified for application to a comparator for classifying the rotator as damaged or not.

Patent GB-277648-A (GB)
Abstract: 277,648. Levey, W. H. Sept. 14, 1926, [Convention date]. Two-stroke.cycle engines; driving-gear.-A scavenging and induction piston 1 in the cylinder is driven through mutilated tooth gear, so that it remains stationary near the cylinder head while the power piston 2 performs its out stroke but follows up the piston during the exhaust period at the same time drawing a charge of mixture into the cylinder through an inlet valve 4. The piston 1 returns to the cylinder head at a more rapid rate than the power piston; during the return movement the previously induced mixture is compressed and delivered to the combustion chamber through holes 28, 29 in the piston and past the spring- pressed valve 11 carried by the piston. The power piston compresses scavenging air in the crank case the air entering the cylinder through a transfer passage. The piston 1 is driven from a spur wheel 17 through a connecting rod 16 cross-head 15 and piston rod 13; a tension spring 27 surrounding the piston rod tends to move the piston down in the cylinder. The spur wheel 17 is rotated from the crank shaft by a mutilated wheel 18 the teeth on which are sufficient to turn the wheel 17 through the major part of a revolution. The wheel 17 carries pins 23, 24 projecting from one side two rollers 21, 22 adapted to wipe over two cam surfaces 25, 26; these surfaces project from the side of the wheel 18 to different amounts, are circular for the major part of the circumference of the wheel and extend over the one not formed with teeth. At normal speeds the momentum of the parts causes the return of the piston 1 to the cylinder head after the teeth 20 on the wheel 18 has driven the piston and associated parts through the wheel 17, and the teeth have become disengaged; to ensure return at all speeds against the action of the tension spring 27 the cam surface 26 engages the rollers 22 and completes the revolution of the wheel 17. The two surfaces 25, 26 engaging the rollers 21, 22 hold the wheel 17 and piston stationary during the power stroke. In an alternative form, the wheel 17 has a roller engaging a groove cam in the wheel 18. The piston rod 13 may be carried through the power cylinder the driving gear for the piston being housed in the crank chamber.

Abstract: 994,637. Friction clutches. FRANCAISE DU FERODO S.A. Aug. 1, 1961 [Aug. 2, 1960; Nov. 28, 1960; April 1, 1961], No. 27909/61. Heading F2C. In a plate clutch engaged by a diaphragm spring 17 fulcrumed at 18 on a driving housing 15, a presser plate 14 is drivingly connected to the housing by tangential flexible strips 25 which are secured at their leading ends to the housing by rivets 27 and are secured at their trailing ends to the presser plate by rivets 28. Each flexible strip 25 may have a spring strip 32 associated therewith, each spring 32 being secured at its leading end to the housing by a rivet 27 and being forked or apertured at its trailing end to pass freely around the rivet 28 and bear against the strip 25 so as to withdraw the presser plate on disengaging the clutch. Alternatively, springs may be attached to the presser plate and pass over the back of the diaphragm spring 17 to ensure withdrawal of the presser plate. The presser plate may be formed at 27<SP>1</SP> with rivet holes for securing the flexible strips to the housing for the reverse direction of rotation. If the clutch is liable to be used for either direction of rotation two sets of flexible strips are used, secured to the housing at 27 and 27<SP>1</SP> respectively, one set serving for forward and the other for reverse drive. Some play is permitted between at least one set of strips and the rivets 28 to allow axial movement of the presser plate. Ventilation passages may be provided in the presser plate.

Abstract: Trans-stilbene is prepared by the reduction of benzoin and recrystallization twice from ethanol and once from trichlorethylene. To reduce the benzoin content the ethanolic solution is treated with a mixture of hydroxylamine hydrochloride and sodium acetate to form benzoin oxime which remains in solution.  Further purification may be obtained by crystallizing from the melt or scrubbing with n-pentane and also by distillation at about 180 DEG  C. and 2 mm. of mercury pressure. The stilbene is subsequently crystallized from the melt to form single crystals (see Group III).ALSO:<PICT:0761050/III/1> <PICT:0761050/III/2> <PICT:0761050/III/3> <PICT:0761050/III/4> <PICT:0761050/III/5> <PICT:0761050/III/6> Single crystals of substances, e.g. stilbene, tolane, naphthalene and anthracene, suitable as phosphors for measuring nuclear radiation, are grown from the melt by passing vessels containing the substance and of the shape shown vertically downward through a furnace while initiating crystallization at the apex of the cone or the extremity of the capillary depending therefrom.  The baffles 3, 8, 9, 17, 23 and/or the capillaries 4, 14 or 24 prevent entry into the main body of the liquid in the vessel of more than one growing crystal.  The orifices in the baffles and the diameters of the capillary tubes are approximately 1 mm. in size. In the vessel of Fig. 2 the line joining the orifices in the baffles 8, 9 makes an angle with the wall of the cylindrical part of the vessel.  A change in orientation of the growing crystal in a bent capillary may be obtained by suitable choice of freezing rate.  In an example purified stilbene is crystallized in a vessel according to the invention by supporting the vessel in a brass cup carried by a screwed brass rod, the cup being insulated from the vessel and the tip of the vessel touching the rod, the rod being moved downwards by a threaded sprocket at 2.5 to 3 inches per day to cause the vessel to move through a furance.  A temperature gradient of 20 DEG C. per inch is maintained between the upper and lower parts of the furnace, the air temperature in the upper part being 140 DEG C. \sB 2 DEG C. and in the lower part 100 DEG C. \sB 2 DEG C.  The orientation of the crystal grown in a vessel having a baffle wth a bent capillary attached depends on the angle at which the capillary joins the baffle.

A continuous tobacco filler is formed by showering tobacco onto a moving surface to form thereon a stream comparable in cross-sectional size with a cigarette rod filler, and thereafter transferring the stream to a faster-moving conveyer by positively engaging and accelerating successive portions of the slower-moving stream of tobacco. As applied to the apparatus of Specification 646,746, in which tobacco showered from a hopper 1 is collected on a travelling surface as a stream and is passed thereon through a confining passage 3 and delivered to a paper web 4 which moves at a slower speed than the surface, the apparatus is modified in that, to form a more uniform initial stream, the portion of the surface which actually receives the tobacco shower is constructed as a separate conveyer 2 moving more slowly (e.g. at the same rate as the web 4) than the main surface 8, the tobacco stream being accelerated on passing from the member 2 to the member 8 by means such as a wheel 14 with rings of sprocket teeth 15, or optionally staggered rings of radially extending pins, which positively engage successive stream portions. As shown, the members 2, 8 are endless canvas or cotton bands. A bridge 7 is provided between them, and, to form a recess to co-act with the wheel 14, the band 8 initially slopes upward from a receiving position slightly below the delivery part of the band 2. Piano wire or other cantilever springs 16 acting on each side of each ring of teeth 15 press the tobacco stream onto the bands 2, 8 during transference therebetween. The wheel 14 rotates at such a speed that the ends of the teeth 15 move at about the same speed as the band 8. Side guides 13 for the tobacco stream are provided. These guides are continuations of the side walls of the passage 3 and may be of equal spacing therewith, in which case the wheel 14 may have three toothed or like rings; or, as shown, may have bevels 13c so that the portion of the guides upstream of the wheel 14 are of wider spacing than the side walls of the passage 3 and of the same spacing as the side walls of a trough 5 in which the band 2 runs.
