Title: Improved process for refining light oils and distillates thereof obtained from the distillation or hydrogenation of coal or coal tars and products produced thereby
IPC: C10G29/00
Filed: 1934-03-16
Abstract: <PICT:0435194/III/1> Light oils obtained by distillation or hydrogenation of coal or coal-tars are purified by short hot or cold treatment with about 0,3 per cent of a sulphur chloride alone or with a catalyst and about 0,15 per cent of sulphur chloride.  The sulphurous resinous, asphaltic, and unstable constituents are converted into high boiling and less soluble substances which are separated by distilling off the oil.  Suitable catalysts are fuller's earth, finely divided clay, copper, lead, zinc, anhydrous sulphides of the metals copper, lead, tin, arsenic and antimony.  The precise amount of sulphur chloride is determined by preliminary test, e.g. by adding small amounts to the oil, refluxing and distilling until the distillate is of the required quality.  In the apparatus shown, light oils are fed by a pipe 11 to a fractionating column 10 heated by a steam coil 13 in a residue-receiving position 12 provided with draw-off means.  Sulphur mono-chloride is fed in by a pipe 19 and hydrogen chloride passes off by a pipe 14 to an absorber or to a chamber 16 for conversion to chlorine which is passed to a chamber 18 to be united with recovered sulphur to form sulphur chloride.  The Specification as open to inspection under Sect. 91 describes the use of small amounts of a sulphur chloride, preferably less than 1 per cent.  This subject-matter does not appear in the Specification as accepted.

Title: Improvements in or relating to gramophone record changers for mixed-size records
Inventor: COSTA HARRY DA
IPC: G11B17/16
Filed: 1954-03-23
Abstract: 792,961. Gramophone record changers. PLESSEY CO., Ltd. May 20, 1955 [March 23, 1954], No. 8453/54. Class 40 (2). In a gramophone record changer the starting position at which the pick-up arm 3 is lowered for the beginning of play on to any of three different diameters of records dropped on to the turntable 5 is automatically selected by two independently movable feeler members 21, 27 which are respectively engaged and operated by records of the intermediate and largest diameters during their fall to the turntable. Although 10 inch and 12 inch records may be mixed, 7 inch records must be at the bottom of the stack to be played first and following release of a 7 inch record, which record clears both feeler members 21, 27, a cycling cam (not shown) moves downwards (Fig. 1) a link 15 and pivots a quadrant 15b about a pin 8. Against a pin 16 on the quadrant is biased by a spring 18 (Fig. 1A) a lever 6 also pivoted about pin 8, and lever 6 follows this movement during which its roller 7 contacts a lever 1 fixed to the pick-up arm support shaft 2 and thereby carries with it the pick-up arm, until the lever 6 is arrested by engagement of its 7 inch position step 10 with a tooth 19 of a slidable latch plate 20. Movement of the quadrant 15b continues and the pick-up shaft 2 drops into a depressed cam groove 15e whereby the pick-up not shown is lowered to the record. Following resetting of the mechanism, if the next record is of 10 inch diameter it will depress feeler member 21 to move downwardly (Fig. 5) about its pivot pin 24 a trip lever 23 of which it is a part. In so doing it disengages a stop pin 25 (Fig. 1A) fixed to the trip lever 23 from a prong 20a of the latch plate 20 which under the tension of a spring 26 slides until its tooth 19 strikes the toe 27b of the feeler arm 27 in which location the tooth arrests the lever 6 by engaging its 10 inch position step 11. Alternatively had the next record been of 12 inch diameter its edge would have struck the feeler surface 27e of arm 27 which pivots about a fulcrum edge 27d (Fig. 5) and urged by a spring 28 moves its toe 27b from a step 29 (Fig. 1A) in the changer base plate 9 to a step 30 to which location the tooth 19 of the latch plate 20 moves when the latter is released by the record also tripping feeler member 21; in this location tooth 19 is engaged by the 12 inch step 12 of lever 6. Once feeler member 21 has been tripped by one of a stack of records it remains tripped and the 12 inch or 10 inch location is determined by actuation or not of feeler arm 27 which is reset to step 29 before each record is played by an edge 6b of lever 6. When the last record started upon the turntable spindle (not shown) has been fed to the turntable the record steady arm falls and moves a locking lever 17 (Fig. 5) about a horizontal fulcrum of a pivot 17a so that it engages a projection 6a of lever 6 when the last record has been played to prevent further inward movement of the pick-up arm.
