Title: Manufacture of aluminium fluoride
IPC: C01F7/50
Filed: 1969-03-25
Abstract: 1307993 Aluminium fluoride ALBRIGHT & WILSON Ltd 20 March 1970 [25 March 1969] 15616/69 Heading C1A Aluminium fluoride is produced by scrubbing gases, which contain volatile fluorine compounds, with an aqueous solution containing aluminium fluoride or aluminium fluosilicate, precipitating silica therefrom by the addition of Al(OH) 3  at elevated temperature, cooling to precipitate hydrated AlF 3  and filtering or centrifuging to remove mother liquors. The hydrated AlF 3  may be calcined to obtain anhydrous aluminium fluoride. The gases which contain volatile fluorine compounds may be evolved as by-products in the-concentration of wet process phosphoric acid. The scrubbing of gases is preferably carried out at temps. in the range 23-95‹ C. while precipitation of silica is achieved at a temperature of not less than 100‹ C. and the precipitation of aluminium fluoride at not more than 92‹ C. by seeding with hydrated AlF 3  crystals. Part of the scrubber liquor may be recycled, without prior treatment, after dilution with part of the mother liquor from the crystallization of AlF 3 .

Title: Positive yarn feed systems
IPC: D04B15/48
Filed: 1969-06-20
Abstract: 1320502 Knitting machines TRIPLITE Ltdl8 June 1970 [20 June 1969] 31214/69 Heading D1C A positive yarn feed has a band, tape or the like 15 to apply feed to the yarns which is driven by a variable diameter wheel 20 adjusted by a stepping motor 29 activated as and when required. As shown in a circular knitting machine, positive yarn feeding rollers 13, 14 are driven from the tape or band 15. Pulley 20, see Specification 1320501, comprises blocks 21 engaged by belt 19 and slidable under the control of a cam disc 24 on pairs of parallel radial spokes 22 carried on a holder 23 secured to shaft 12. Cam disc 24 is rotated on shaft 12 by the engagement of its toothed edge with pinion 26 driven by an A.C./D.C. stepping motor 29 carried on a disc 27 on shaft 12 to vary the diameter of pulley 20. Slots 35 in a disc 34 rotatable with shaft 12 pass through a photo-electric scanning head 36 producing impulses to energize the stepping motor for forward or reverse movement. A shaft 41 on top of motor 29 aligned with shaft 12 through a pulley and belt drive, drives a pulley 44 with rods 48 carrying a disc 49 with a single slot 50 which co-operates with a further scanning head 51 similar to head 36. When, during knitting, a change in the yarn feed is required, head 36 will be switched on, e.g. by a patterning chain, for the required direction of movement of motor 29, the amount of adjustment being controlled by covering slots 35. For finer adjustment, disc 50 is used, adjustment being by substituting different sizes of pulley 42. Resetting of pulley 20 is achieved by running motor 29 continuously in the appropriate direction to restore it to its initial state. Thus the necessary progressive variation in loop size to produce shaping of a stocking or leg blank for a panti-hose can be produced.

Drum 2 comprises an open structure of spaced rollers 8 mounted on a framework rotated by a variable speed motor (11) or indirectly by the belts, and the belts are urged against the drum by adjustably spring-loaded outer rollers 12 mounted on the fixed machine frame. Belts 1, 4 are driven by separate motors driving spring-loaded rollers 3, 5, and the belts and drum 2 may be driven at different speeds to break up the sludge and improve dewatering. Scraper 25 and sprinklers 26 remove dried sludge and clean the belts. Filtrate is removed via vessels 19, 20, 21. Rollers 8, 12 may have surface grooves (23) and be double tapered, and belts 1, 4 may have edge beads to seal the pressing space therebetween (Figs. 8, 9, not shown). Rollers 12 may increase the pressing force applied towards the discharge end of the press. Sludge may be mixed with coagulant upstream of the press (Fig. 1, not shown).

Title: Digital calculating apparatus for performing the cordic algo- rithm
IPC: G06F7/544
Filed: 1971-08-09
Abstract: 1331410 Digital calculators SOLARTRON ELECTRONIC GROUP Ltd 9 Aug 1971 8365/73 Divided out of 1321067 Heading G4A A digital calculator for performing the cordic algorithm includes two registers loaded with initial values. In successive cycles the value in one register is added to, or subtracted from, a multiple of the value in the other register, the result being placed in the one register for use in the next cycle. Means are provided for correcting the result to a required degree of accuracy after each two cycles. The multiples for successive pairs of cycles are respectively R<SP>-1</SP>, R<SP>-2</SP>, R<SP>-3</SP>, &c., R being the radix used in the calculation. The calculator may be used to calculate Sin (# + 2α) and Cos (# + 2α) or to convert Cartesian co-ordinates x, y to polar coordinates r, #. In the former case the initial valves are Sin # and Cos #, and in the latter case x and y. As described R = 10 and α is restricted to increments whose tangents are 0À1, 0À01, 0À001, &c. In the calculation of Sin (6 + 2α) and Cos (# + 2α), after two cycles the content of one register is Sec<SP>2</SP>α. Sin (# + 2α) and of the other is Sec<SP>2</SP>α. Cos (# + 2α). Since Sec<SP>2</SP>α = 1 + Tan<SP>2</SP>α the approximate value of, for example, Sin (# + 2α) can be obtained by multiplying the value in the register by 1-Tan<SP>2</SP>α. The register content will now be (1-Tan<SP>4</SP>α) Sin(# + 2α). As Tan α = 0À1 for the first two cycles, Tan<SP>4</SP>α = 0À0001 and the discrepancy between the value in the register and the true value of Sin (# + 2α) may be considered negligible. The multiplication by 1-Tan<SP>2</SP>α is performed by subtracting from the contents of the register the contents multiplied by Tan<SP>2</SP>α i.e. by 0À01. To obtain a higher accuracy the value in the register may be multiplied by Tan<SP>4</SP>α and added to itself, giving the result (1-Tan<SP>8</SP>α) Sin (# + 2α). Here Tan<SP>8</SP>α (i.e. 10<SP>-8</SP>) is negligible. A further two cycles of the algorithm may now be performed, using Tan α = 0À01. The result is corrected in a manner similar to that described above.

As shown H 2  produced escapes to the atmosphere via annular spacing 44 between the outer wall 26 and the cap flange 38. When O 2  is consumed by the microorganisms in the sample, CO 2  is evolved into space 16 to be absorbed via aperture 23 in container 19 of the adaptor 17 be KOH solution 20 with glass wool wick 21 in the container 19, thus generating a slight vacuum in chamber 47 which lowers the electrolyte level in space 29a, breaking contact with electrode 50 and starting electrolysis. The DC source may be rectified AC. A transistor regulator circuit ensures a constant current flow through preset resistors when the DC source is energized through a relay. An elapsed time meter turned on when the voltage is applied is representative of the amount of BOD.

Title: Method for treating water in heat exchange systems
IPC: C02F1/50
Filed: 1992-12-11
Abstract: The present invention comprises an improved method and apparatus for treating water in heat exchange systems. The present invention automatically and inexpensively provides an effective chemical to process water systems at times and in proportion to the need for water treatment in such systems. When used in evaporative cooling systems (10), the present invention adds the treatment chemical to the system via the make-up water (44). The make-up water acquires a substantially constant concentration of treatment chemical as it is passed through a device (42) containing a treatment chemical. The constant concentration of chemical is achieved by dividing the make-up flow into two streams within the device, saturating the smaller of the two streams with chemical, and re-mixing the two streams. The biocide agent used in the preferred embodiment of the invention is prilled elemental iodine. <IMAGE>
