Title: Process for recovering naphthalene with a solidification point above 78íµ. from tar oil fractions
IPC: C07C7/14
Filed: 1959-12-11
Abstract: Naphthalene having a solidification point above 78 DEG C. is obtained by cooling, e.g. to 15-25 DEG C., a naphthalene-containing tar oil having an acid oil content of at least 7%, separating the crystals and covering with 20-120% of the crystals of a caustic alkali or caustic phenolate solution at a temperature above the solidification point of the product.  The acid oil may be carbolated oil obtained from the tar and need not be recovered separately or some of the oil obtained by centrifuging the crystals may be recycled to dilute the feed.  The naphthalene oil should contain less than 10% of methyl naphthalene oil.  The oil is cooled at a speed slower than 2.5 DEG C. per hour to 5-35 DEG C. below the solidification point of the mixture and the washing solution may be 0.5-23 DEG C. hotter than this solidification point.  The caustic solution can be reused until saturated with acid oils which can be recovered by treatment with carbon dioxide.

Title: Apparatus and process for the rapid processing of segmented data

Filed: 1973-09-18
Abstract: 1436601 Processing data COMPAGNIE HONEYWELL BULL 18 Sept 1973 [26 Sept 1972] 43815/73 Heading G4A In apparatus for processing segmented data held in m addressable segments in a memory unit, each segment having a descriptor represent - ing for example its address and length, the descriptors of the first n segments requested are entered in order in the storage elements D 1 -D n  (Fig. 48) in an auxiliary descriptor table UTA, these descriptors being replaced if the descriptor of a subsequent sement requested is not in the table UTA in the storage elements D n -D 1 . As described, initially two orders ROP, ROR are supplied by the command unit (UCM, Fig. 1, not shown) of the processor (UEX). This results in the resetting of presence indicators P 1 -P n  (Fig. 4A) and reference indicators R 1 - R n  in a control unit UCT for the table UTA. The next order (TMR, Fig. 3A, not shown) results in the identification number N of the first segment requested by the programme being entered in a first register (RM). A comparison order (CNS) is then issued for comparing this number with numbers stored in segment identification registers S 1 -S n  (Fig. 4B) associated with storage elements D 1 -D n . Since initially no comparison occurs a commond signal (v 1 ) is issued which results in a general descriptor table being searched to obtain the descriptor of the desired segment and stored in a second register (EX, Fig. 3A). With all the presence indicators reset the next-order (TEP) results in a command signal (v 2 ) which causes the processor to generate an order which results in a signal a 1  being generated to permit the contents of the first and second registers to be entered into the segment identification register S1 and the descriptor storage element D 1 . The signal a 1  also resets the presence and reference indicators P 1 , R 1 . This process is repeated for subsequent segments called. When subsequently a segment is called its identification number is compared with the contents of all the registers S 1 -S n  and if comparison occurs, the associated comparator C 1  delivers a signal C IV  to enable read-out of the associated storage element D l . If comparison does not occur and if any of the reference indicators is in its "0" state the data relating to the segment is entered into the highest numbered store D j  associated with a reset indicator R j , its number being simultaneously entered into the segment identification register S j . If all the reference indicators are set, they are all reset and the data is entered into the store D n . Subsequent use of any of the stored descriptors results in its reference indicator being set so that it is not replaced until storage associated with unused descriptors has been used.

A machine for welding the longitudinal edges of a pipe blank comprises a welding apparatus having a welding member past which the blank is moved and a device for feeding and guiding the blank, the device having a feeler sensitive to turning of the blank about its axis and being adapted to feed the blank and also to steer the blank in response to the feeler to keep the edges in a correct position relative to the welding member. A pipe blank is taken from a stock of parallel blanks and lifted on to a roller conveyer 12, Fig. 3, and it is moved with its seam downwards along a roller carrying bar 16 through a station 20 where its seam is welded from the inside. A strip 23 having a slot aligned with the gap in the blank may be welded to each end of the blank by a device on a carriage 26 to promote satisfactory end welds. A strip may extend between blanks to allow continuous welding. After welding at station 20 the pipe is moved transversely and turned through 180 degrees and then welded on the outside by a similar apparatus. The station 20 comprises a frame having an opening for the pipe and a roll 30, beneath the pipe keyed to a shaft 32 and mounted in a carrier 34 pivoted at 36 in the frame. The carrier has a plate 40 carrying a motor 42 which drives the roll 30 through a chain 44 to move th e pipe longitudinally. Rotation of the roll about the pivot to effect guiding of the pipe is effected by a reversible motor 46 on a pivoted plate 52 driving a threaded sleeve 48 co-operating with a screw 54 pivoted to the plate 40. An arm 106 pivoted at 108 to a bracket 74 on the end of the hollow bar 16 carries a sharp edged wheel 110 projecting into the gap between the blank edges and the arm extends between contacts connected to the motor 46. A castor wheel 64 provided on the bracket opposes the roll 30 and a pair of swivelled rolls 78 on the bracket oppose a pair of swivelled rolls 80 in the frame 25 which are acted on by pneumatic cylinders. Lateral rolls (not shown) acted on by pneumatic cylinders are also provided on the frame to act on the outside of the pipe. In operation the pipe is advanced by the roll 30, electrode wire 102 is fed from a pit adjacent the conveyer 12 through the bar 16 to an electric arc torch 104 secured to the arm 106. Flux may also be supplied to the torch. If the rotates the arm 104 is caused to pivot to close one or other of the contacts to start the motor 46 in one direction to rotate the roll 30 to cause the pipe to be rotated back to its original position.
