Abstract: 124,461. Chance & Hunt, Holly, A. E., and Mott, O. E. Jan. 7, 1916. Nitro compounds.-In a continuous nitration process, a current of the organic compound to be nitrated and a current of acid are caused to flow in opposite directions through the plant, continuous of the reacting materials and subsequent separation being effected throughout. In the apparatus shown in Fig. 2, a series of say sixteen nitrating pots is employed; each pot is divided by a partition d into an agitating space containing stirrers c and a separating space f, the two portions communicating by a hole in the partition; pipes g near the top and pipes h near the bottom connect each separating space to the next agitating space in the series. For producing trinitrotoluene. mononitrotoluene is supplied to one end pot of the series by the pipe k, sulphuric acid is supplied at the other end by the pipe j, and nitric acid or a mixture of nitric and sulphuric acid is supplied to one or more intermediate pots by the pipe l; the stirred mixture passes to the compartments f, where it separates into two layers, the lower layer of acid passing to the bottom of the next agitator, while, the upper layer of partly nitrated body passes to the upper part of the next agitator on the other side, and so on; spent acid finally leaves by the end pipe h and nitro body by the end pipe g. The pots may be on a level as shown, or may be arranged in cascade, the flow of one liquid taking place by gravity, while the other is raised by a pump. Or the mixture of parent nitro body and acid may be pumped to a separator from which the two bodies flow in opposite directions through the plant. Fig. 3 shows a modification in which the pot a contains two separators, one n for the nitrated body, the other o for acid. The process may also be effected in a vessel containing a rotating vertical shaft carrying etirrers, spaces being provided at the top and bottom for separation, and acid and parent organic body being supplied at the top and bottom respectively.

Title: Improvement in electrical musical instruments
IPC: B65D45/20
Filed: 1935-01-05
Abstract: 454,502. Shaft couplings. HAMMOND, L., 2915, North Western Avenue, Chicago, U.S.A. Jan. 5; 1935, No. 432. Convention date, Jan. 19, 1934. [Class 80 (ii)] [See also Groups XXXVIII, XXXV, and XXXVII] Relates to an electrical musical instrument having a number of generators corresponding respectively with the notes of the equally tempered scale, the alternating currents therefrom being combinable in the requisite proportions to give a large number of different timbres. The generators comprise phonic wheels driven by a synchronous motor through flexible couplings and gearing. Bus-bars, each carrying one order of partials, may be connected by the operation of corresponding selector devices to any number of turns of the primary of a transformer whose secondary is connected to the amplifier and loud-speaker. The constant-speed synchronous motor, Fig. 6, is driven either by alternating current at 744, Fig. 27, or by direct current at 746 interrupted by a tuning fork interrupter 748. A fly-wheel 294 fixed to a shaft 312 has movement relative to shaft 264 positively limited by pins 302, 300 and is connected to shaft 264 through springs 306 and a friction washer 298. The drive is transmitted from shaft 312 to the first shaft 370 of a number of generator shaft sections, through a helical torsion spring 396, friction both between the end of the shaft 312 and a sleeve 394, and between the coils of the spring, assisting in damping hunting. The generator wheels G are arranged in sets of four (or three and a dummy) with their magnets in compartments formed by a series of vertical plates 314. The generator shaft sections, as 370, which are arranged in line with shaft 312, are supported in bearings at the bottom of slots in the partition plates 314, and are universally connected together by rigid plates 384, Fig. 27, having spaced axial projections loosely engaging apertures in gearwheels on the ends of the shaft sections. The shaft sections carry gear-wheels as 119, one in each compartment and each meshing with two driven gears as 149. Each driven gear, as 149, drives two generator wheels G on the same shaft 402, Fig. 8, through a further resilient coupling, comprising a spring wire 414 with a positive limiting pin 410 working in an arcuate slot in the gear 149. The resiliency of the spring 414 is such that any hunting is at a frequency below audibility, producing at most only a tremolo. Adjacent rotor shafts 402 are staggered vertically as shown, in bearings 400 in the plates 314. The bushes 404 are preferably bored after attachment of the generator wheels G, for accuracy.

Title: Improvements in internal combustion engines
IPC: F02B75/22
Filed: 1921-01-07
Abstract: 156,705. Baltimore Oil Engine Co., (Assignees of Wygodsky, L.). Aug. 22, 1917, [Convention date]. Valves.-A heavy-oil engine working with a compression pressure of approximately 300 lb per sq. in. and igniting its charges by the heat of compression is charged with air by doubleacting pumps 32. Admission and delivery to and from the pumps are controlled by inlet valves 33 and discharge valves 34. An inlet valve comprises a series of split spring-rings 50 held in position and spaced apart by projections 61. The operative faces of the rings seat upon the outer face of the depending member 48. The exhaust valves are constructed similarly to the inlet valves, the pumps delivering into the interior of the valve sewings 57. During the normal operation of the pumps, the disc valves 54, which remain out of action, are retained upon their seatings 53<c> by springs 56. Each disc valve carries a spindle which slides in an extension 51 of a fixed valve seat 48 and compressed air for starting is admitted to the pumps through the pipes 46 and the hollow stems 53 of the disc valves. The admission of compressed air forces the valves 54 into contact with the exhaust valve seatings 57, the opening of one valve 54 forcing the other valve 54 into its closed position upon its seat 53<c>. A rod 58 communicates motion from one valve disc to the other and thus prevents a valve disc from remaining upon its seating 57 during a discharge period.

Title: Ultrasonic thickness measurement system
IPC: G01S15/10
Filed: 1968-01-05
Abstract: 1,216,511. Ultrasonic thickness measurement system. MAGNAFLUX CORP. 5 Jan., 1968 [20 June, 1967], No. 862/68. Heading H4D. The thickness of a workpiece having generally parallel front and back surfaces is determined from the duration of an output signal from a digital counter, the signal persisting for the interval between two selected echo pulses of a series produced by multiple reflection of an ultrasonic pulse between the surfaces and applied to the counter. In the embodiment shown, transducer 14 launches a pulse through water couplant 12 towards workpiece 11 and applies the resulting series of echo pulses to gate 21. Logic circuitry including delay multivibrators 30, 34 ensures that gate 21 opens just after the first (i.e. front surface) echo. Subsequent echoes pass through gate 21 to digital counter 22 comprising cascaded bi-stables 23- 26 whose outputs are combined by selectively operable OR gates (network 37-62) to give a counter output signal on line 63. This signal is applied to the logic circuitry to close gate 21 and reset counter 22 when a selected number (sixteen, eight, or four, depending on which of the OR gates are operable) of echoes have been passed to counter 22. The counter output signal persists during counting of this number and its duration (proportional to workpiece thickness) is determined by circuit 65 supplying a printer 65a. The logic circuitry is reset when printer 65a is actuated.
