Abstract: 1,166,698. Discharge lamp arrangements. GENERAL ELECTRIC CO. 6 Oct., 1967 [9 Jan., 1967], No. 45640/67. Heading H2H. [Also in Division H1] A starting and operating circuit for a sodium lamp 40 comprises a laminated magnetic assembly 41 having a first choke section N1 and a saturated auto-transformer section N4 which with capacitors C1, C2 forms a voltage stabilizer and resonates to a frequency preferably slightly higher than that of the A.C. input on terminals 16, 18. The lamp is fed through L1, part of N4, and a second choke section N2. The high open circuit lamp voltage before the lamp strikes is also across a potentiometer R4-R8 which ignites a neon lamp S1 discharging a capacitor C5 thus firing a thyristor SCR1 at about each positive half-cycle mid-point, which discharges a capacitor C4, fed through another capacitor C3, through a winding N3 thus inducing an additive voltage in winding N2 sufficient to ignite the lamp. On ignition the potentiometer voltage falls, hence SCR1 is no longer fired. Diodes D1, D2 limit the voltage across capacitors C4, C5, respectively on negative half-cycles. Resistor R1 limits the current in SCR1 and D1 due to voltage induced in N3 by the heavy current surge in N2 immediately after the lamp ignites.

Title: Production of fats by interesterification of natural triglycerides
IPC: C11B7/00
Filed: 1961-12-28
Abstract: Fats having melting characteristics different to those of the starting fats are obtained by randomly and/or directly interesterifying such natural fats as tallow, lard, palm, palm kernel, sperm or coconut oils which preferably contain less than 0.2% free fatty acid and less than 0.01% water in the presence of an alkaline interesterification catalyst, such as 0.05-0.5% of an alloy of sodium and potassium or an alkali or alkaline earth metal C1- 8-alkoxide, and afterwards neutralizing the catalyst by the addition of water, whereby soap is formed in such quantity as to form an oil-in-water dispersion of fat particles in the soap solution and at a temperature at which both solid and liquid fat particles are present in the dispersion, thereafter adding further water, if necessary, to bring the total amount of water added to at least 0.5 parts per part by weight of fat and then separating the lighter liquid fat phase from the heavier phase of solid fat suspended in aqueous soap solution.  By a directed interesterification process wherein the interesterification rate is greater or lesser than the rate of crystallization of the reaction mixture, higher or lower melting triglyceride fractions respectively may be obtaned as desired; in addition, the interesterification may be carried out on the fraction remaining after the highest melting triglycerides have been removed.  Again, the starting fat may first be randomly interesterified to reduce the high melting triglycerides, and then directedly interesterified.  The water added to neutralize the catalyst is preferably either soft, or contains hardness sequestrants such as polyphosphates or aminopolycarboxylates; it may also contain other salts, e.g. sodium chloride or sulphate, wetting agents, e.g. tetrapropylenebenzene sulphonate, and emulsion stabilizers, such as methyl- or carboxymethyl-cellulose, cellulose oxyalkyl sulphonate and sulphate, alginates, and poly-acrylates and -methacrylates, and is preferably added in two portions, so that the first, amounting to about 0.1-1% by weight of the fat, forms a concentrated alkaline solution which is able to form a flowable suspension of fat particles in the solution. The phases may suitably be separated by centrifuging and the unrequired fractions obtained may, if suitable, be returned to the process.  The process may be applied to the production of a cocoa butter substitute from coconut and soyabean oils, a summer margarine from coconut and palm oils, a mayonnaise oil from palm oil, a winterized cottonseed oil from cottonseed oil, a solid fat suitable for suppositories from palm kernal oil, and hard fats from coconut and palm kernal fats.
