Title: Improvements in or relating to weaving
IPC: D03D47/00
Filed: 1949-10-31
Abstract: 701,522. Weft pattern mechanism in circular looms. COOPER, H. J. Oct. 24, 1950 [Oct. 31, 1949], No. 25924/50. Divided out of 701,506. Class 142(2) Mechanism for selecting weft for winding into coils for transfer to the shuttles of a circular locm as described in Specifications 699,737 and 701,506 comprises feeders arranged in groups, together with pattern mechanism for projecting one feeder from every group in turn to a position where it delivers its weft to the coiling mechanism. Feeder mechanism, Fig. 3. Each group of feeders is carried by a block 38 which is continuously reciprocated vertically. The feeders 36 (two per group, as shown) are suspended on links 37a, 37b and are provided with weft guide eyes 43 and clamps 45. To select a feeder, the pattern mechanism described below projects a stop 20 into the path of a three-armed lever 39, the stop being locked by a latch 56 dropping into a notch 51. As the block 38 rises, the lever 39 is rocked to project the feeder 36, which is then located by a latch 62 engaging a notch in the top of the block 38; as the feeder reaches its fully projected position the link 37a pushes the clamp 45 open by means of a rod 50. Continued upward move- . ment of the block 38 lifts the latch 56 to allow the stop 20 to retract. As the block 38 reaches the end of its downward movement, the lever 39 strikes a fixed stop (not shown) whereby the feeder 36 is retracted. Pattern mechanism, Fig. 1. The stops 20 described above are actuated by slides 16 which can be lifted into the path of one of a series of lugs 26 disposed helically round a rotating drum 25; each lug is wide enough to actuate the slides pertaining to one group of feeders, the number of lugs being equal to the number of groups. Two pattern cards 9 each control half the slides 16 through lifting bars 10 having reading needles 11; the two cards are advanced alternately by pawls 7 operated bv cams 34 on the drum 25. Before a card is moved, the associated bars 10 are raised bv a cam 14 or 15; when allowed to fall, one bar in each group encounters a blank on the card and holds up its slide 16 so that, as the drum 25 rotates, the lugs 26 move these slides endwise in succession.

Title: Improvements in or relating to the extraction of sulphonic acids from acid sludge by-products of mineral oils
IPC: C10G17/10
Filed: 1949-10-12
Abstract: Sulphonic acids are extracted from acid-sludge obtained as a by-product in the refining of mineral oils with sulphuric acid or oleum by washing the sludge at a temperature of between 20 DEG  and 60 DEG  C. with 100 to 400 per cent by weight, relative to the sludge, of a mineral oil having a Redwood I viscosity at 100 DEG  F. of between 50 and 200 seconds, and separating the wash oil containing the sulphonic acids from the sludge.  If the wash oil has a viscosity-gravity constant not exceeding 0.875 and an aniline point not less than 60 DEG  C., the sodium salts of the extracted sulphonic acids will have a preponderance of sodium salts preferentially soluble in hydrocarbon oil; if the wash oil has a viscosity-gravity constant not less than 0.900 and an aniline point not exceeding 50 DEG  C., the sodium salts of the extracted sulphonic acids will have a preponderance of sodium salts preferentially soluble in water.  The sulphonic acids may be recovered from the wash-oil by means of an aqueous alcoholic solution of an alkali such as caustic soda and the resulting sodium sulphonates may be isolated and the free sulphonic acids obtained by treatment with, e.g. sulphuric acid.  The acid sludge may be prepared by reacting a naphthenic type lubricating oil distillate with 10 per cent fuming sulphuric acid at 40 DEG  C.  In examples: (1) sulphonic acids yielding sodium salts predominantly preferentially oil-soluble are recovered from an acid sludge using as wash oil a mineral oil distillate of viscosity-gravity constant 0.831 and aniline point 97 DEG  C.; (2) sulphonic acids yielding predominantly preferentially water-soluble salts are extracted from the same acid sludge by means of an Edeleanu aromatic petroleum extract from mineral oil and having a viscosity-gravity constant of 0.909 and an aniline-point of 26 DEG  C. U.S.A. Specification 1,087,888 is referred to.  According to the Provisional Specification, the wash oil may be any raw or refined oil, e.g. a naphthenic base oil of viscosity 70-150 seconds at 100 DEG  F.
