Patent GB-717239-A (GB)
Title: Improvements in or relating to process for refining aluminium
Filed: 1951-08-01
Abstract: A process for separation of aluminium from material containing aluminium and one or more of the elements manganese, iron, silicon, titanium, copper, chromium and nickel comprises reacting the material with halide at an elevated temperature, e.g. with aluminium trichloride at a temperature of at least 1000 DEG C. to produce a gaseous mixture containing aluminium and the other elements in dissociating halide form, conducting the mixture through a condensing region while maintaining zones of successively lower temperature along the path of the mixture and condensing at the successive zones fractions containing metallic aluminium and respectively decreasing proportions of the said and other elements.  The process may involve reduction of the pressure of the gaseous mixture while conducting it into the condensing region, e.g. by providing an orifice in the path of travel of the gaseous mixture the reduced pressure being maintained throughout the condensing region.  The temperature in the condenser decreases along the path of movement of the gaseous mixture from one value to a substantially lower value, both of said values being within the temperature range for deposit of aluminium from the gaseous mixture.  Specification 582,579 is referred to.

Title: Improvements in the production of potassium nitrate
IPC: C01D9/08
Filed: 1929-06-13
Abstract: 332,359. H÷fer, P., and Kaliforschungs-Anstalt Ges. June 13, 1929. Potassium nitrate is produced by the action of potassium chloride on the nitrate of a readily hydrolysible metal, for example, aluminium or iron. The mixture, if hot, is cooled to separate potassium nitrate. The mother liquor is evaporated with the evolution of hydrochloric acid gas, either until nitrous gases begin to escape, or until most of the chlorine has been expelled from the solution. Water, potassium chloride, and nitric acid or nitrogen oxides are added to restore the original concentration. The solution is cooled, potassium nitrate separated, and the operations repeated.

Title: Improvements in generators of electrical oscillations of saw-toothed wave form
IPC: H03K4/34
Filed: 1938-06-21
Abstract: 516,357. Valve generating circuits. TELEFUNKEN GES. FœR DRAHTLOSE TELEGRAPHIE. June 21, 1938, No. 18376. Convention date June, 21, 1937. [Class 40(v)] In a back-coupled oscillator in which the rate of flow through a grid-controlled electron discharge valve is periodically changed by negatively charging a condenser in the grid circuit through a rectifier and an inductance reactively coupled with the valve anode, a current-limiting impedance 17 is arranged in series with the control grid for restricting the potential to which the grid can be raised. The condenser 11 is charged slowly from battery 16 through impedance 15, and anode current flows at a slowly-increasing rate. When a synchronising pulse is received on an additional grid of valve 10, or when the voltage across the condenser exceeds that across coil 12, the condenser 11 and the magnetic energy of coil 14 discharge rapidly through rectifier 13, so that condenser 11 is charged in the opposite sense and the cycle then repeats. Normally grid current flows when the grid potential exceeds the cathode potential, and this varies the rate of charge of condenser 11. To prevent this a current-limiting impedance 17 is provided which maintains the grid potential practically constant after grid current starts and the anode current remains steady. Saw-tooth potentials are produced across condenser 11, whilst saw-tooth current flows in coil 12.

Title: Improvements in or relating to apparatus for producing artificial threads
IPC: B65H51/22
Filed: 1930-06-21
Abstract: <PICT:0363692/IV/1> In applying stretch to artificial thread by methods involving the passage of the thread one or more times around a wheel, the thread is displaced laterally on the wheel by means of a guide comprising a smooth roller, preferably tapered.  The roller may be associated with a housing designed to catch coagulating liquid thrown off by the thread.  As shown, the thread 2 coming from the coagulating bath passes in turn behind a post guide 21, around a wheel 1, around a roller 4, again around the wheel 1, and finally into a funnel 31 leading to a spinning bucket.  The roller 4 has a smooth uniform surface and is mounted freely on an axle 5.  A housing 10 is associated with the roller 4, and is provided with ribs which direct the spray caught by the housing on to the axle 5, which is thus lubricated, the liquid being ultimately returned to the coagulating bath through a conduit 17.  The block 12 to which the housing 10 is secured may be provided with a recess 20 to receive drippings from the wheel 1 and guide 21.  A modified construction of the housing 10 is described, Fig. 4 (not shown), in which the post guide 21 is secured directly to the housing, and the drippings from the wheel 1 are used to lubricate the axle 5.  The post guide 21 may be dispensed with if the thread is first run horizontally on to the wheel 1.

Title: Improvements in or relating to digital process control apparatus
IPC: G06F7/556
Filed: 1964-05-07
Abstract: 1,039,596. Automatic control. HONEYWELL Inc. May 7, 1964 [May 21, 1963], No. 19009/64. Heading G3R. In a digital automatic control system the logarithms of signals representing errors in a number of process variables are derived and further signals corresponding to ranges of values in which the error logarithms fall are selected to control correction of the variables. Electrical signals from units 1, 2, 3, which may for example be thermocouples or differential pressure units, representing the errors in a number of process variables, are applied in succession by a stepping switch 7 through an analogue to digital converter 10 to a magnetic core type unit 11 which derives quantised logarithms of the error signals. The method of selecting quantised logarithms for various bases is described. The outputs from unit 11 are applied to a digital computer 12 which computes for each variable the necessary number of increments of correction which is then stored in a magnetostrictive delay line 25 associated with a register 15. A counter 20 associated with the output of an oscillator 21 times the operation of stepping switch 7 to select the variables at one frequency, and also times the operation of a core type matrix 37 at a higher frequency to cause a number of increments of adjustment of each corrector 45, 46, 47 to correct each process variable. A unit 43 compares the number of correction increments applied with the required number in register 15 and renders matrix 37 inoperative when the numbers are equal.
