Title: Stable pourable oleaginous suspensions
IPC: A23D9/02
Filed: 1956-10-26
Abstract: A pourable oleaginous shortening of normally solid gly prides able to exist in a stable beta phase and comprising 1-20 per cent. by weight, of the shortening in a normally liquid glyceride vehicle is obtained by mixing the solid and liquid glycerides at a temperature high enough to melt all of the solids, cooling, in not more than three minutes, to below the alpha melting temperature of the solids, and tempering the mixture to convert non-beta crystals to a beta phase so that at least 60 per cent. of the solids are in the beta phase.  The liquid vehicle can be derived from one or more of the oils from cottonseed, soybean, peanut, rapeseed, sesame seed, sunflower seed, or an oil fraction obtained from palm oil, lard or tallow, or a low molecular weight synthetic fat (defined).  The solids of iodine value not above 12 are fats made by hydrogenating the oils from cottonseed, sunflower seed, linseed, hazelnut, soybean, peanut, olive, corn, or palm, or lard or tallow or their mixtures or they can be mixtures of mono-, di-, and tri-glycerides formed by reacting saturated triglycerides with excess glycerine, or they can consist primarily of triglycerides, tristearin, tripalmitin or palmito distearin.  Prior to crystallization, the liquid mixture can be seeded with beta phase crystals at a temperature lower than their melting point. Preferred tempering temperature is 90 DEG -120 DEG F., and the mixture may be added during or after such tempering.  Specifications 574,807, 660,610 and 810,277 are referred to.

Abstract: 963,214. Semi-conductor testing. TELEFUNKEN A. G. Sept. 26, 1960 Sept. 24, 1959], No. 32927/60. Drawings to Specification. Heading G1U. A high frequency electric current is fed by electrodes to spaced areas on the surface of a semi-conductor, the frequency being raised until the conductance and/or susceptance of the semiconductor, measured between the electrodes in known manner, is independent of frequency. In this way errors that may occur in interpreting measurements at lower frequencies due to the effects of the surface inversion layer are avoided. The life duration of the charge carriers, is measured by disturbing the balance of the bridge, used for the conductance &c. measurements, by illuminating the semi-conductor with a flash of light, and measuring by an oscilloscope the time taken for bridge balance to be restored.

Title: Preparation of leavened bread
IPC: A21D8/04
Filed: 1961-09-14
Abstract: A process for preparing leavened bread in which a micro-organism preparation containing substantially exclusively the micro-organism Lactobacillus cereale is used as leaven is characterized in that the micro-organism preparation has been obtained by culture at a temperature of from 52-54  DEG C. on a medium consisting of dextrinized flour, glucose or maltose, a source of growth substances and nitrogen and if necessary an agent (A) for starting, and/or an agent (B) for accelerating, the fermentation.  (A) may be malt; (B) may be ammonium sulphate.  A preferred medium consists of dextrinized flour, malt, ammonium sulphate, dried wheat germ and water.  After sterilization, the medium is inoculated with the culture of bakers leaven containing Lactobacillus cereale and agitated at 52  DEG C. until the culture reaches its maximum acidity.  Surviving bacteria were re-planted five times in the same sterile medium to produce the desired strain of Lactobacillus cereale having improved acidogenic capacity, resistance to acidity and producing almost entirely lactic acid.  To make the bread, 4 litres of leaven of which 10 c.c. have an acidity corresponding to that of 12-15 c.c. decinormal acid, are used for 80-100 kg. of flour.

Filed: 1927-12-08
Abstract: 290,923. Wischin, R. Nov. 3, 1927, [Convention date]. Oils, purifying.-Used lubricating oil from internal combustion engines is refined by mixing it cold with 5-7 per cent concentrated sulphuric acid, gradually heating in the course of several hours to 50‹-60‹ C., passing the mixture through a sludge separator and a filtering agent, e.g. Fuller's earth, and injecting steam into the mixture. A mixing vessel 1 has a water jacket 3, stirrer 5 and wave breaker 6. A tube 8 extends therefrom into a container 9 with an outlet 11 forming a sludge separator, and the oil passes by a tube 13 near the top to a filter 14, which maybe heated by a water jacket 30, and comprises a cylindrical container 16 partly filled with Fuller's earth and having removable caps 15. A sheet metal, felt covered inverted filtering cup 17 with a perforated top 18 separates the earth from the oil chamber. A tube 19 projects from the cup 17 above the level of the oil supply pipe 13. The oil then passes by a pipe 20 to an electrically heated distilling drum 21, into which passes by a pipe 35 steam at 300‹ C. from a steam generator 33 and super-heater 34. Dry oil is finally withdrawn by a pipe 24, steam and fuel oils having passed to a condenser 23. The water supply passes by a pipe 27 to the water condenser and to a pipe 29 through an electric heater 25 to the water jackets of the mixing vessel and filter.
