Title: Metal coating process
Inventor: JACKSON ALBERT EDWARD
IPC: B22F7/04
Filed: 1963-06-17
Abstract: In a process of coating and elongated metal substrate e.g sheet, strip, wire or rod, a first coating of a colloidal solution of a suitable metal hydroxide is applied followed by a coating of a powdered material such as a metal or metal oxide, the coating is dried and then rolled and heated to form a sintered coating.  The suitable hydroxides are Al(OH)3; Zn(OH)2; Ni(OH)2; FeOH)3; Cr(OH)3; Mg(OH)2 and Mn(OH)2 and the powdered coating material may be Al, Sn, Ni, Zn, Fe, steel or brass or Al2O3.  The hydroxide coating may be applied by dipping, spraying or rolling the substrate into an aqueous colloidal solution containing 2-5 g/l of the hydroxide and the metal or metal oxide powder may be applied by the rotating metering roll described in Specification 1,035,256.  After drying at 100 DEG -300 DEG C. and rolling to effect 1/2 -5% elongation the powder layer is sintered at 250 DEG -650 DEG C. for aluminium or 700 DEG -1000 DEG C. for nickel.  The colloidal aqueous solution of the hydroxide is formed by electrolysis of an aqueous solution of a soluble salt of the metal.ALSO:In a process of coating an elongated metal substrate e.g sheet, strip, wire or rod, a first coating of a colloidal solution of a suitable metal hydroxide is applied followed by a coating of a powdered material such as a metal or metal oxide, the coating is dried and then rolled and heated to form a sintered coating.

Title: Improvements in or relating to processes of modifying starch and the improved starchresulting therefrom
IPC: C08B30/12
Filed: 1946-08-15
Abstract: Starch is modified by treating it with 0.05 to 0.5 per cent, based on the dry weight of the starch, of aluminium chloride hexahydrate at a starch temperature between 20 DEG  and 105 DEG  C., the starch containing from 1 per cent to 30 per cent, preferably 1 - 20 per cent, of moisture based on the total weight of starch and moisture, the pH value of the mixture of starch and aluminium chloride being between 2.8 and 3.4, preferably between 3.0 and 3.4, this pH value being determined by slurrying the mixture of starch and aluminium chloride in distilled water to a density of 10 DEG  B<\>ae at 60 DEG F., shaking the slurry for 30 minutes and then centrifuging, the pH value of the separated liquor being measured in the usual way. Starch containing more than 30 per cent of moisture may be treated either by reducing its moisture content before bringing it into contact with the aluminium chloride or by mixing it with the aluminium chloride and reducing its moisture content under such conditions that reaction does not take place. Thin boiling starch may be prepared by treating starch containing 9 - 12 per cent of moisture at 75 - 95 DEG  C., and pyrodextrin by treating starch containing 5 - 7 per cent of moisture at 90 - 105 DEG  C., the time of treatment in both cases being 30 - 45 minutes. The modification of the starch may be arrested by treating the product with an alkaline reagent, preferably gaseous ammonia to adjust the pH to 5.0 to 6.0.

Abstract: 1330568 Servo control WARNER & SWASEY CO 19 April 1971 [9 April 1970] 25065/71 Heading G4H A system for supplying electrical power to a load includes a means for supplying power, said means having a plurality of conditions in each of which it has a maximum power capability, means for controlling the supply of power to the load up to the maximum in each of said conditions in response to an input signal, and means for changing the condition of the means for supplying power as a function of the magnitude of the input signal. As described a machine tool 12 is driven in accordance with a digital command signal modified by a digital signal generated in response to actual movement of the tool. The modified (error) signal is converted into an analogue signal and fed to the driving motor via an amplifier. The signal is also fed to a threshold detector 24 which, in conjunction with a switching circuit 26, connects one of a number of different supply voltages to the amplifier. The Specification describes the various circuit components in some detail. Briefly the threshold detector comprises an A/D converter consisting of several circuit elements connected in parallel, each element including a diode poled to conduct either negative or positive signals, an input resistor and an amplifier having a feedback resistor. A variable bias source is connected to the inverting input of each amplifier which thus generates a saturated output when its input exceeds the bias voltage. The bias voltages of the various elements are set at increasing values so that the device acts as a number of threshold triggers. Two embodiments of the switching circuit 26 are described involving silicon controlled rectifiers and power transistors respectively. In the former a comparator determines whether the voltage supplied is the same as that required, an operative rectifier being shut down when a change in supply is required.
