Title: Improvements in Continuous Stills for Coal Tar, Mineral Oils and similar Products.
Inventor: MOORE HAROLD
IPC: C10C1/04
Filed: 1916-08-29
Abstract: 104,636. Moore, H., and Day, C. Aug. 29, 1916. Mineral oils and tars, distilling.-In plant for the continuous distillation of coal-tar, mineral oils, &c., wherein a number of stills are arranged at different levels so as to be heated by furnace gases passing in the opposite direction to that of the tar &c. through the stills, the distillate vapour from each still is separately condensed after passing through a coil in the preceding still to assist in heating the tar &c. therein. The tar &c. is fed by a pipe K to the still 1 and flows thence to the stills 2, 3 in succession by pipes A, B, and the pitch or residue leaves by a pipe C, after which it may serve to preheat tar passing to the still 1. Distillates from the stills 2, 3 pass by pipes R, Q through coils N, L in the stills of next lower temperature before passing to their separate condensers. Baffles F, G are arranged in the path of the tar in each still. To allow for extra frothing in the stills of lower tmperature, the surface of the tar therein compared with their volume is greater than in the stills of higher temperature.

Filed: 1932-04-30
Abstract: 393,067. Controllers with auxiliary switches. AMBERTON, R. and ELECTRICAL APPARATUS CO., Ltd., Vauxhall Works, South. Lambeth Road, London. April 30, 1932, No. 12493. [Class 38 (iii).] Auxiliary switches 11, 12 and 13, 14 are closed when a drum controller is moved in a forward or reverse direction respectively, by means of a member 4 carrying a co-operating contact 10 and frictionally driven by a member 3 rotated with the controller shaft 2. The auxiliary switches are in the circuit of a selfmaintaining main contactor and are opened by any reverse movement of the controller towards the " off " position, so that the circuit is never broken at the drum contacts. The closing circuit of the main contactor may be completed at the first forward or reverse position of the controller, by closing the appropriate auxiliary switch, and the maintaining circuit passes through the closed auxiliary switch and is independent of the position of the controller, so that when the main contactor opens, either as the result of a backward movement of the controller or the operation of an overload relay, it can be reclosed only by first returning the controller to the first forward or reverse position and closing the appropriate auxiliary switch. The controller is described as applied for running a series motor up to speed, and reversing its direction of rotation, a brake solenoid and a blow-out coil being provided.

Abstract: 1410416 Measuring phase; decoding NOKIA AB OY 15 March 1973 [17 March 1972 12550/73 Heading H3H A decoder for a non-return-to-zero phase coded signal where each bit is represented by an A.C. signal having a particular phase occurring for a predetermined time, the value of each bit being represented by the difference in phase of the bit length and the immediately preceding phase of the signal, comprises means for measuring digitally the phase of the signal driving each bit length and means for subtracting each measured value from the immediately preceding measured value. The coded signal is received at a and is shaped to rectangular form at 3 and applied to EX-OR gates 5, 6 together with a reference signal of the same frequency as the input, the reference generator producing two outputs d, f differing by a constant 90 degree phase. The received signal is also passed to a block 1 containing an envelope detector, electrical resonance circuits and shaping circuits where signals b coincident with each bit length are produced, which signals are passed to a device 2 where 255 counting pulses are produced during a half cycle of input signal a during each bit length. These pulses are applied to AND gates i and j where the number of pulses passed by the gate i during a bit length is equal to the phase difference of the reference signal d and the input a. The number passed by gate j gives the sign of the phase difference according to whether the number produced at 12 is greater or less than 128. Change-over switches 10, 11, 20 apply the output from gate i to one of counters 13, 14, and the output from counter 12 to one of storage devices 15, 16. Under the control of the signal b the switches are operated so that each nth measured value may be subtracted at 17 from the (n-1)th value. The nine-bit word resulting is code converted at 18 to a 4-bit word and read out in serial form at 19.
