Title: Improvements in or relating to stockings and a method of and means for dyeing the same
IPC: D06B5/00
Filed: 1934-11-29
Abstract: <PICT:0442616/IV/1> <PICT:0442616/IV/2> <PICT:0442616/IV/3> Stockings are dyed, by repeated dipping to different depths, with the calf portion from the heel to the top of lighter or darker colour than the shin portion from the ankle to the top, with the colour shades merging into one another, as shown in Fig. 4, to give an appearance of slimness or fullness, as desired.  The stockings may be mounted, as shown in Figs. 1, 3, on separate wire frames 6, secured by clips 5 in holes 4 in a frame 3, and these holes, as well as slots 9 and adjusting nuts 10, provide means for controlling the depth of immersion of the stocking.  Teeth 7 on a transverse support 2 of the frame 3 mesh with gear wheels rotating in alternate directions to move the stockings to-and-fro in the bath 11.  The undyed knitted stocking may be sewn with a thread of the colour to be produced at the darkest part of the stocking to ensure uniformity of appearance in the stocking.  The Specification, as open to inspection under Sect. 91 comprises also the application of the invention to toning or shading off the colour of garments covering arms, legs, hips, and the like, and describes an apparatus wherein the depth of immersion of the garment is controlled by varying the volume of the dye bath, or by varying the amount of the dipping movement, whilst at the same time the concentration of the bath may also be altered.  If desired, also, the colour may be sprayed on to the garment.  An apparatus is described wherein the stockings are supported on forms on a rail which can be pivoted, to reverse the stockings, and which can be raised and lowered by eccentric gearing.  This subject-matter does not appear in the Specification as accepted.

Patent GB-627873-A (GB)
Title: Improved process of treating wool scour water
IPC: C02F1/76
Filed: 1946-11-22
Abstract: <PICT:0627873/III/1> Calcium hypochlorite or bleaching-powder is added to wool scour water containing albuminous matter, grease, dirt or sand, manure, urea compounds, burrs, straw, soap and alkali, in an amount sufficient to obtain a curd of the foreign matter.  Wool scour water at approximately 110 DEG  F. flows into a treatment tank 11 where calcium hypochlorite or bleaching powder is added from a supply tank 12 at a rate of 1 part of a solution containing approximately 8 per cent chlorine to 35 parts scour water, the pH of the mass being thereby reduced to between 7 and 8.  Air is bubbled in at the bottom. After curdling occurs, the liquid and heavier solids overflow into one or more settling tanks 13, while the lighter solids pass to a washing tank 15 where steam is admitted at 16, which washes and heats the contents to 190 DEG  F. Agitation is provided by paddles 17, 18. The mixture then passes to the bowl 25 of a centrifuge 24, the water passing through a conduit 261 to a drain 46, and the grease still containing much water, passing to a further steam tank 30 and centrifuge 38, the grease being finally collected at 45.  The liquid and heavier solids in tank 13, after standing for at least six and preferably eight or more hours, separate into a clean liquor 47, which passes to drain 46, and a sludge 48, which is pumped to another settling tank 52, where it is treated with concentrated mineral acid, e.g. sulphuric acid, in a quantity sufficient to lower the pH to between 4 and 6, at which the soap present is least soluble.  The whole then settles for a further six to eight hours or more, after which the sludge passes to a heater 57, the clear liquor 54 being drained away.  The sludge is steam-heated to substantially 200 DEG F. and filtered in a press 59 to yield a filtrate of water and wool-grease, which separates in the vessel 61, the grease being recovered through the conduit 62 and the water discharging to drain. The dirt, soap and protein remain in the filter.  The calcium hypochlorite or bleaching-powder may be added as a 70 per cent solution, proportionately smaller quantities being required.

Title: Machine tool control devices
IPC: G06G7/18
Filed: 1972-07-25
Abstract: 1402893 Automatic control of size M POSSATI [trading as APPARECCHI ELETTRONICI MARPOSS] 25 July 1972 [30 July 1971 (2)] 34656/72 Heading G3R To produce workpieces with dimensions with pre-set limits, a machine tool is adjusted according to the mean value of the measured dimensions, the mean value being updated for each machined workpiece. As shown, circuit 19 receives signals from measuring head 12 dependent upon the maximum size of bearing rings 11 from a grinding machine, circuit 19 calculating the mean value. Using this value, the derivative of the mean and the number of workpieces between the machine tool and the measuring head, the actual size of the ring being machined is calculated and kept within pre-set limits. Circuit 24 compares the measured and mean values, and provides an indication if the tool has to be changed or dressed. After such a tool change or dressing, counter 34 blocks the signals from head 12 to circuits 19, 24 until a pre-set number of rings have been measured i.e. to allow for the distance between the machining and measuring points. The system response may be increased by adjusting circuit components. In circuits 19, 24 (also Fig. 3 not shown) which include operational amplifier, the mean value is obtained by charging a capacitor (49) through a FET (52) made conductive for each measurement by a monostable circuit (53).

Title: Process and apparatus for producing multi-coloured particulate products
IPC: C11D3/40
Filed: 1965-08-16
Abstract: Multi-coloured particulate detergent products are prepared by continuously spraying uncoloured detergent fluid through a plurality of spaced nozzles into a spray-drying tower while concurrently spraying coloured detergent <PICT:1080098/C4-C5/1> fluid into the tower through at least one other nozzle.  In Fig. 1, hot uncoloured detergent liquid from crutcher 19 is drawn through pipes 21 and 23 by a pump 22 into an annular manifold 12 mounted outside a spray-drying tower wall 11.  From the manifold equally spaced radially projecting nozzles 13-16, fitted with spray-heads 18, extend into the tower and serve to spray the uncoloured liquid entering manifold 12 into the tower.  The fifth nozzle 17 is separately supplied with hot coloured liquid from crutcher 24, in which uncoloured liquid fed by gravity from crutcher 19 is coloured by colour solution entering from reservoir 29. The ratio of coloured to uncoloured liquid fed into the tower is controlled by a valve 33 which is periodically opened and closed by a timer 34. In Fig. 2 (not shown), there is illustrated an arrangement in which all five nozzles are connected to the manifold and thus receive uncoloured liquid, but one of them also receives colouring material at a point between the sprayhead and the manifold.

Title: Process of producing cellulose esters
IPC: C08B7/00
Filed: 1927-12-28
Abstract: 282,793. Ruth-Aldo Co., Inc., (Assignees of Barthelemy, H. L.). Dec. 28, 1926, [Convention date]. Cellulose acetates and other carboxylates.- For the esterification of cellulose and of nitrocelluloses of low nitrogen content, there is employed an acetylation mixture containing acid anhydride, particularly acetic anhydride, and a catalyst such as sulphuric acid, together with a reagent capable of effecting a mild oxidation of the cellulose &c. The process is particularly applicable to the acetylation of cotton, having the effect of giving uniform products from cottons which would otherwise produce acetates of varying properties particularly as regards their viscosity characteristies. The reagent must be added in such an amount that the amount of active oxygen employed is not in excess of 0.3 per cent of the weight of the cotton. Suitable reagents are manganic sulphates, manganic acetate, chromic acid, mono-persulphuric acid, manganic and permanganic acid, and peracetic acid. In examples, cotton is first treated with acetic acid, and then with acetylation mixture containing a limited proportion of acetic anhydride, sodium bichromate or permanganate, sulphuric acid and acetic acid, if necessary with cooling; later the remainder of the anhydride is added, and the reaction allowed to proceed until solution is complete. The cellulose carboxylate is then partially saponified by known methods and after flocculation is thoroughly washed to remove the salts.

Title: Improvements in or relating to tractor change speed gear control
IPC: F16H61/34
Filed: 1945-12-31
Abstract: 604,409. Variable-speed gear selector mechanism. FORD MOTOR CO., Ltd. Dec. 31, 1945, No. 35225. Convention date, Jan. 18, [Class 80 (ii)] [Also in Group XXXI] The steering column 62 of a tractor has a gear-shift rod 70 mounted thereon for rotary and reciprocating motions, which are transmitted to a link 88 arranged to be rotated about a fulcrum 89 to select a gear when the rod 70 is reciprocated, and to a second link 84 which is reciprocated to engage the gear when the rod 70 is rotated. The engine 11 of the tractor 10 transmits a drive to a power take-off drive shaft 18 and by a tube 19 to a variable speed-gear 13 through a conventional clutch 20. The driving shaft 22 of the variable-speed gear is tubular and carries integral pinions 34, 35, 37, 36 which are meshable with the sliding pinions 38, 39, and 41, and the fixed pinion 40 on the driven shaft 23 which drives the independent axles 32 through the bevel gears 25, 26 and gears 28, 30. The frame 12 has rigidly secured thereto a steering column 62 housing a gear-shift rod 70 extending along it, the rod has a lever 69 at its upper end by means of which it may be rotated and reciprocated, the springs 75, 76, normally retaining the rod in the neutral position. The links 84, 88 connected to the lower end of the rod 70 are arranged to operate a lever 106 universally pivoted at 107 and engageable at its lower end 109 with the selector forks 100, 101, 102, of the variable-speed gear. The movement of the gear-shift rod 70 is limited by an H-plate 79 in which a finger 78, on a lever 80 connecting the rod 70 with the link 84 travels. Reciprocation of the lever 69, and correspondingly the rod 70, against the springs 75 or 76 pivots the links 85, 87, 88 about the fulcrum 89 to cause the forked end 112 on the pin 110 in the ball 107 to swing the lever 106 transversely to select one of the three selector forks 100, 101, 102. Rotation of the rod 70 causes reciprocation of the link 84 through the lever 80, and pin and slot 82, 83 to move the lever 106 longitudinally to engage the selected gear. The mechanism is arranged within sheet metal covers 93, 94 to be readily accessible.
