Abstract: 1,229,460. Purification of sulphuric acid. PULLMAN Inc. 11 April, 1968 [14 Nov., 1967], No. 17723/68. Heading C1A. A process for decontaminating and concentrating sulphuric acid from 65% by wt. or less to at least 85% by wt. acid, the dilute acid containing organic contaminants from a hydrocarbon alkylation process, comprises digesting and settling the dilute acid for at least ¢ hr. at 175-500 F., separating most of the lighter liquid organic contaminant layer from the heavier liquid sulphuric acid phase to remove at least 70% of the contaminants leaving a contaminant concentration of not more than 1%, passing this acid into a vacuum evaporating zone containing a pool of 85-91% sulphuric acid so that the volume of dilute acid: volume of the pool is between 1: 100 and 1: 10,000, evaporating the water at a temperature of 300- 450 F., and a pressure of 25-150 mm. Hg, and withdrawing 85-91% sulphuric acid from the pool at a rate equal to the rate of addition of dilute acid to the pool. The acid to be purified may be of 90% concentration, when dilution to 65% is necessary. The settling and digestion stage may produce particles of carbon in the acid. These may either be removed by filtration, or allowed to remain in the acid, and the reconcentrated acid again used in the alkylation, when the carbon may be removed with the lighter liquid contaminant phase in the next digestion step. The recovered acid may be passed to a second evaporation zone, having a sulphuric acid condenser, where water is evaporated at 300-450 F. and 0À2-50 mm. Hg, to give a 92-98% acid. This second zone may be a tray evaporator. The combined vapours from the top of the evaporator may be fed to the condenser, and the condensed vapours used to dilute acid at the start of the process. This diluted acid may be used as the condenser coolant. The digestion may be carried out in one or more stages, each having its own settling zone, or all the digestion zones feeding a common settling zone. A plurality of acid pool evaporation zones may be used, with progressively higher acid concentrations.

Abstract: 1,232,294. Cleaning torque converters. OWATONNA TOOL CO. 13 Sept., 1968 [15 Sept., 1967], No. 43685/68. Heading A4T. A torque converter is cleaned by continuously circulating cleaning fluid therethrough and simulteaneously rotating the converter about a central axis. The converter 25 is releasably mounted by bolts and nuts 30, 31 on a plate 28, a hub 29 of which is locked to a drive shaft 32 of a motor 17. Cleaning fluid is continuously supplied to the converter by a stand pipe 53 mounted in a collar 52 of a splash guard 50 provided with a bearing 51 and supported by an adjustable bracket 60. A hollow cap 55 threaded on to the pipe end is biased into abutment with the converter runner hub 43 by a compression spring 54. Cleaning fluid is supplied to pipe 53 through a fitting 70 connected to a line 71 that is connected to a motor driven pump (73). The fluid flows as shown through pipe 53, cap 55 and hub 43, through the converter, and out in the space between pipe 53 and converter drive coupling 40. It then falls through a filter 11 into a reservoir 12, from where it flows to the pump inlet via a line (75), filter (76), and a line (77). The rotation of the converter causes its curved elements 45, 46 to lift cleaning fluid above the central axis and allow it to drain downwardly towards said axis. Air pulses are introduced into the fluid by a line 90 with a timed solenoid-controlled valve (91). A drain hole may be drilled in the converter. Cap 55 may be replaced by a larger diameter cap (100, Fig. 4) that abuts the converter stator hub 41. To clean an oil cooler (C, Fig. 1), line 71 is disconnected from fitting 70 and connected to a hose (110) connected to the cooler. A second hose (111) connected to the cooler overlies filter 11.

Abstract: 1,257,631. Selective signalling. ENGLISH ELECTRIC CO. Ltd. 2 April, 1969 [9 April, 1968], No. 17066/68. Heading G4H. [Also in Division G1] As a workpiece 1 is rotated in a lathe, its inside or outside diameter is measured by urging a wheel 2 against it and counting by means of a unit 14 the number of pulses produced by a generator 4, the total number of pulses recorded on a display 13 giving a direct indication of the diameter. Each revolution of 1 is signalled to the counter 6 by a pulse produced each time a magnetic or light reflecting marker 9 passes a magnetic or photo-cell transducer 8. The wheel 2 is pivoted at 43 on an arm 37 which normally rests against a stop 46 integral with arms 42, 45 of a member 36 feed to a tube 25. At its other end the tube 25 which is journalled in bearings 21, 23, is fixed to a member 27 which may be reciprocated in a housing 15 by a screw shaft 29, a threaded block 28 and a coupling 33 connected to a motor 34. Should the arm 37 be pivoted in an anticlockwise direction away from the stop 46 due to a -fault in the apparatus or misalignment of the wheel 2 then rods 38 and 39 are slid against compression springs to 'operate micro switches 57, 61 and 66 in an electric control circuit, Fig. 5. -In operation the machinist first correctly sets up the unit -3 on the machine so that the wheel 2 may correctly engage the piece 1, if necessary rotating the arm 37 and the pin 43 through 180 degrees about the bolt 52, and then starts machining the piece 1. When the operator is ready to check the diameter of the piece he energizes the circuit controlling the motor 34 to rotate the block 28 and move the tube 25 and cradle member 36 so as to bring the wheel 2 against the workpiece 1. The motor 34 continues however to move the arm 37 and tube 25 until the stop pin 46 leaves the arm which then pushes the rod 38 to the left to operate the micro switch 57 and switch off the motor. The pulses then produced by the generator 4 are counted after one or ten revolutions and the indication of diameter read off from the display unit 13. The operator may retract the wheel 2 after measurement by switching the motor circuit to retract.

In an arrangement for automatically maintaining the belt tension in an expanding-pulley gear in which both pairs of conical flanges 2, 2a move relatively axially in opposite directions for a ratio change by turning a spindle 7, via a hand wheel 6, to pivot levers 5 on tension blocks 8 screwed on opposite pitch threads on a spindle 9, the spindle 9 is rotatable and subjected to a continuously applied torque tending to tighten the blocks 8 to decrease the distance therebetween to automatically maintain belt tension. As shown, a continuous torque is applied to the spindle 9 by a spiral spring 12 acting through a pawl 26 and ratchet wheel 14, the pawl 26 being carried by a disc 20 fast with a sleeve 19 to which the inner end of the spiral spring 12 is secured at a notch 21, and the ratchet wheel 14 being fast with the spindle 9, the spring pre-load being adjusted by turning (i.e. setting) the disc 20 in the direction of arrow 28 by, for example, a screwdriver engaging slots 29 in the disc periphery. The outer end of the spiral spring 12 is retained on a pin of a second plate 22 locked by a pin 24 of a releasable catch 23, the second plate 22 and sleeve 19 being separately freely journalled on the cylindrical hubs 18 of the ratchet wheel 14 and a second oppositely arranged ratchet wheel 13 which are pinned together at 15 to the spindle 9. During normal automatic belt tensioning via the spring 12 and ratchet pawl and wheel 26, 14, a second ratchet pawl 30, 32 is held clear of the second ratchet wheel 13 by a peg 31 on the releasable catch 23 (Fig. 3) such that the second ratchet wheel 13 freely turns with the ratchet wheel 14 and spindle 9 under the influence of the belt tensioning spring 12. Removal of the belt for maintenance purposes is readily effected without disturbing the automatic belt tensioning arrangement simply by raising the catch 23 to release the pin 14 from the slot 25 of the second plate 22 and simultaneously engage the second pawl 30, 32 with the ratchet wheel 13 whereby the two oppositely acting ratchets 13, 14 nullify the torsional loading of the spring 12 on the shaft 9.
