Abstract: 1443904 Shearing; crimping MATTISON MACHINES Inc 18 Nov 1974 49823/74 Headings B3W and B3Q A hydraulically-actuated tool, Fig. 1, for working on a cable, comprises an anvil, not shown in Fig. 1, mounted in a hooked portion 46 of a tool head 26 integral with a cylinder 20, a hollow piston 28 of which supports a cooperating tool, also not shown. The piston is biased against the action of fluid admitted through a screw 35 by a spring 37 engaging a flange 31 on the piston and a flange 34 on a rod 32 extending through the piston and secured to the screw 35. For shearing, a blade 60, Fig. 3, in a holder 54 is mounted on a boss 29 on the piston and an anvil 76 (Figs. 4 and 5, not shown), with a rib (74) engaged in a slot (72) in the forked portion, is retained by engagement of a spring loaded ball with a necked portion of a stud (82) on the anvil located in a bore 83 in the hooked portion 46. Two convex faces (78) on the anvil are aligned with complementary concave edges 68 on the blade 60. For crimping a sleeve to a cable a crimping tool 96 with locating flanges 100, 102, is mounted on the piston and co-operates with a U section anvil retained by a stud 116 the neck of the stud being long enough to allow the anvil to move axially during crimping, the limbs then conforming more closely to the surface of the hooked portion. The anvil may leave portions of reduced thickness at the base of each limb to facilitate this bending action.

The stitches may bridge entire helix turns as shown in Fig. 1 or may bridge only the lower limb thereof as shown in Fig. 15. A two thread chain stitch seam may be used. The monofilament is laid by a curved guide 11, 12 which oscillates back and forth, fingers 4 and 5 holding down the laid filament at the interlocking head and rearward bend sides respectively. The guide 11 and fingers 4, 5 are driven by the sewing machine (see Division D1) in synchronism with the needle and looper, as are upper and lower combs 1, 2 which engage the completed coil and feed the fastener in direction B. The guide 11, 12 may accommodate a textile core (15, Figs. 11, 12 not shown) which will extend within the helical turns. Two elements may be made simultaneously to provide a complete fastener. The fastener elements are 'fixed' thermally by, for example, ultrasonic means, and may be flattened as at 24 to weld the arms of the elements to the stitches.

Title: Method of treating raw-wool wash-and/or rinse water and apparatus therefor

Abstract: 1505860 Treating raw wool wash and rinse water ALFA LAVAL and INSTITUT TEXTILE DE FRANCE 23 Dec 1975 [26 Dec 1974] 52662/75 Heading B1D A method of treating wash and/or rinse water from a raw wool scouring process, said water containing wool-fat (wax), insoluble solids and soluble matter, in which the water is passed through a decanting step, a filtering step, and at least one centrifugal step to produce pure wax, is characterised in that all solid products from the decanting, filtering and centrifugal steps are gathered and carried along by at least one fraction of the water containing wax obtained in said centrifugal step(s) and centrifuged to dry said solids, which are then discharged, whilst the conveying water still containing wax and soluble matter is concentrated by evaporation, the resultant concentrate being centrifuged to produce an aqueous stream containing a high wax content which is returned to a preceding operation. In the figure water from a washing machine 18 is passed through a decanter 3, a brushing sieve 6 and a heat exchanger 8 to the first of a series of centrifugal separators 9, each of which has three outlets. A concentrated emulsion fraction is passed to a second centrifugal separator 14, from which pure wax 17 is separately discharged and a further fraction containing fine solids is passed to a centrifugal drier 19 through line 15, whilst nearly pure water is returned to the washing vessel. Residual water and solids from an evaporator step (evaporator 23) are further centrifuged in centrifuge 26, the solids are returned to drier 19, and a liquid fraction containing soluble matter is discharged. A further liquid fraction from centrifuge 26 containing much wax is returned to an earlier centrifugal step (e.g. centrifuge 14). Soluble matter is thereby discharged from the apparatus concentrated in a small volume of water. Dry solids and pure wax are separately discharged. The greater part of the wash water is reused.

[Class 91] [Also in Group IV] Hydroxylated vegetable oils, e.g. castor oil, or the carboxylic acids obtainable therefrom by hydrolysis, are dehydrated by heating them in solution in a volatile hydrocarbon solvent at atmospheric pressure, removing the water formed by distillation, with separation of the distillate into aqueous and non-aqueous fractions, and return of the non-aqueous fraction to the heated solution. The acid so dehydrated may be re-esterified with glycerol. The heating may be effected with the use, as dehydration catalyst, of a normal sulphate of a divalent or polyvalent metal together with a compound consisting of or containing phosphorus pentoxide. In examples, (1) and (2), solutions of different strengths of raw castor oil in petroleum naphtha of b. pt. 95-135‹C., and containing, as catalyst, anhydrous magnesium sulphate and a solution of phosphorus pentoxide in isobutanol, are distilled at (1) 185-220‹ C. for 12 hours, (2) 197-240‹C. for 5 hours, with provision for separating the hydrocarbon from the water in the distillate and returning it to the solution ; the residue is filtered to remove the catalyst and distilled under reduced pressure to remove the solvent; (3) and (4) solutions of different strengths of raw castor oil in petroleum naphtha, and containing, as catalyst, anhydrous alumin- .ium sulphate and anhydrous disodium phosphate, are similarly distilled at (3) 250-240‹C. for 6¢ hours, (4) 215-240‹C. for 5¢ hours, and the residue is similarly freed from catalyst and solvent.
