IPC: C06B25/04
Filed: 1946-12-31
Abstract: <PICT:0631814/IV (b)/1> <PICT:0631814/IV (b)/2> Tetryl is prepared by continuously bringing the aromatic compound to be nitrated and the nitrating acid together, continuously flowing the resulting mixture through a confined extended successively descending and ascending path, concomitantly creating intra-stream circulations at a number of zones along said path, some of said intra-stream circulations being opposingly directed, and continuously discharging the spent acid and tetryl at the end of said path.  The aromatic compound to be nitrated and the nitrating acid may be brought together while violently agitating and cooling the resulting mixture.  Suitable aromatic compounds that may be nitrated to form tetryl are 2 : 4 - dinitromethylaniline, monomethyl- and dimethylaniline.  In an example, a mixture of 2 : 4-dinitromethylaniline, nitric acid, sulphuric acid and water is introduced through inlets 9 and 10 of a U-shaped nitration vessel 1 provided with external cooling or heating jackets and having an outlet 12 for discharging spent acid and product.  Agitators 14, 15, 16, 20, 21 and 22 maintain the mixture uniform, keep any precipitated tetryl uniformly suspended therein, and are so shaped and arranged that they form the mixture into at least two zones of opposing circulation and that no part of the mixture in arm 13 returns to arm 11.  The Specification as open to inspection under Sect. 91 refers to the above process being used for any nitration process, and in an additional example the preparation of nitroglycerine from glycerine is described.  This subject-matter does not appear in the Specification as accepted.

Abstract: 1405437 Digital transmission; synchronizing NIPPON TELEGRAPH & TELEPHONE PUBLIC CORP 18 Aug 1972 [28 Aug 1971] 38529/72 Heading H4P In a synchronizing arrangement for a multilevel system utilizing a FDM channel terminating in an automatic equalizer or equivalent device, the timing phase is adjusted so that signals spaced by time IT as represented by taps (A1, A2) immediately adjacent to an equalizer centre tap, sum to zero, and the carrier phase is also adjusted so that signals spaced by 2T represented by the next adjacent taps (A3, A4), also sum to zero. At the transmitter, Fig. 1 (not shown), binary input signals at (10) are converted to multi level at (14) controlled by a clock (11) and through a Nyquist shaping filter circuit (15) which is modulated at (17) by a carrier of fc and formed into a VSB signal at (18) to which is added a pilot carrier fc at one end of the band, and a clock signal at the other end which combined signal is then transmitted. Single side band may be substituted. At the receiver the carrier is extracted at 20 and through a pre-equalizer 21 signals are passed to a demodulator 22 after which clock signals are extracted at 23 connected in parallel with an auto equalizer 24. This may have 5 taps connected to analogue delay lines 241-4 with a pulse delay time T. The gain of the taps is adjusted by circuits 245-9 controlled by 250- 254 which integrate the outputs of mod-2 adders 255-9. Automatic carrier control unit 100 comprises carrier extraction circuit 20 the outputs from which is phase shifted at 102 voltage controlled by subtraction circuit 101 measuring the difference between outputs 250, 254 which varies the phase change through 102.

Title: Method for the regulation of measuring-out machines
IPC: G01G13/28
Filed: 1961-11-01
Abstract: 939,830. Automatic weight control. FR. HESSER MASCHINENFABRIK A.G. Nov. 1, 1961 [Nov. 4, 1960; Nov. 23, 1960], No. 39053/61. Class 38 (4). [Also in Groups XIX and XL (c)] The output of a measuring out machine for fluent materials is controlled by a batch weigher W so that, whereas large discrepancies cause correction to be applied immediately, smaller errors are summated and correction applied only when the sum reaches a given value. The correction is made by a reversible servomotor SM which may be driven either for a fixed time corresponding approximately to the magnitude of the error or it may make the appropriate number of revolutions required to reduce the error to zero. As shown, the weigher modulates the frequency of an oscillator GV in an analoguedigital converter A, whose output comprises a series of pulses, the number of which in a given time represents the measured weight. These are passed to an electronic counter Z (see Group XIX) connected to storage units +ZS 2  . . .  -ZS 2 . Each storage unit corresponds to a particular band of pulses, the units ZS 2  registering a wide deviation (i.e. a pulse count above a given maximum or below a minimum), the units ZS 1  registering smaller deviations, while ZS registers the pulses when they are correct or within a very small tolerance. Activation of either ZS 2  closes relay R 3  or R 4  causing another relay Sch to energize the motor in a correcting direction. Impulses corresponding to revolutions from a device IG are fed back to the counter Z to be added to or subtracted from the original count. When the result corresponds to a correct count R3 or R 4  is opened by ZS to stop the motor. The smaller errors registered by units ZS 1  are summated in a unit SS which comprises a stepping switch (Fig. 4, not shown). When a given total is reached (a particular step of the switch) relay R 1  or R 2  is closed for a time, determined by a relay ZR 3 , designed to cause the motor to apply the right amount of correction. The control apparatus is reset periodically by contacts 5, cam operated by the machine. In an alternative embodiment (Figs. 5 and 6, not shown) the weigher operates on the core of a differential transformer whose voltage output in magnitude and phase sense thus represents the deviation above or below a desired weight. This voltage operates voltage sensitive relay units (see Group XL (c)) which cause the servomotor to apply correction for an appropriate time, the smaller errors again being summated before initiating correction. It is stated that grossly inaccurate batches may be rejected, and that the controlled machine may be a make-up or afterflow regulator.
