Title: Improvements in and relating to voltage stabilising circuits
IPC: G05F1/607
Filed: 1945-06-14
Abstract: 595,804. Automatic control systems. BROWN, W. F. June 14, 1945, No. 15187. [Class 38 (iv)] Electromotive force.-A stable voltage E2 is derived from a voltage E1 by means of the potential drop across a resistor R2, the current through which is varied by biassing a valve V in accordance with variations in the condition of non-linear resistors due to change in input voltage and output current. This is effected by connecting its cathode to a potential divider R, D1, the lower end of which comprises a non-linear resistor Dl, and its grid to a potentiometer D3, D2, R4, R5, the upper end of which comprises two non-linear resistors. Since the value of the resistor decreases with current, the negative grid-cathode voltage decreases with supply voltage and vice versa, producing the desired effect. Temperature control may be employed to prevent variation in the values of the resistors for a given electrical condition.

Title: Improvements in or relating to the recovery of valuable constituents from fatty oils
IPC: A61K31/16
Filed: 1941-12-09
Abstract: 554,014. Vitamins; fatty oils ; antioxidants. NATIONAL OIL PRODUCTS CO. Dec. 9, 1941, No. 15851. Convention date, Dec. 11, 1940. [Class 2 (iii)] Fatty oils are distilled under high vacuum after being subjected to an extraction treatment comprising extracting the oil at an elevated temperature with an aliphatic or alicyclic solvent miscible with the oil at temperatures above mean atmospheric temperature but partly immiscible at temperatures below mean room temperature, cooling the mixture and removing the solvent layers (c.f. Specifications 547,486 and 549,447). This extraction removes the free fatty acids, highly unsaturated glycerides, nitrogenous compounds, the odiferous and bad tasting ingredients, sterols, anti-oxidants and fat soluble vitamins present in the alcoholic form. Any fatty oil may be treated, namely those containing fat 'soluble vitamins A, D, E and K such as the fish liver oils, palm oil, wheat germ oil, rice germ oil, alfalfa seed oil and tomato seed oil and also fatty oils such as soyabean oil, wheat bran oil, corn oil, olive oil, sesame oil, cotton seed oil, coconut oil, rice oil, linseed oil, oiticia oil, teaseed oil, perilla oil, ground nut oil, poppy seed oil, egg oil, peanut oil and whale oil. By distilling at 140-250‹C. at a pressure below 0.1 mm. the residue obtained by extracting, as above described, an oil containing vitamins A and/or D, a fraction is obtained having most of the vitamin esters. When the oil contains only a small quantity of glycerides having the same boiling points as the vitamin esters, it is desirable to add some of the former to facilitate recovery of the vitamin esters. Separation of the vitamin A and D esters may be effected by collecting two separate fractions. Antioxidants, such as those prepared according to the process of Specification 550,983, and indicators may be added to the fatty residues before distillation. Anti-oxidants and sterols may be recovered from the fractions of the oils extracted.

Title: Measurement of losses in radio-frequency circuits and components thereof
IPC: G01R27/26
Filed: 1943-09-29
Abstract: 568,116. Inductance, capacity, and power factor measurements. MARCONI'S WIRELESS TELEGRAPH CO., Ltd. Sept. 29, 1943, No. 16006. Convention date, Sept. 30, 1942. [Class 37] Apparatus for comparing the electrical losses in two or more electrical circuits includes means for impressing equal radio-frequency voltages upon said circuits, means for rectifying the voltage developed across said circuits, means for comparing the rectified voltages, and a connection from the source of radio-frequency voltages for biassing the rectifier so that it will not rectify voltages below a predetermined minimum. Fig. 3 shows an arrangement for comparing the factor of merit or Q of the two coils 34, 35. The output from a radio frequency oscillator 10 is applied through small coupling condensers 51, 52 and a variable shunt condenser 54 to a switch 31 which can apply the voltage alternatively to coil 34 or coil 35 tuned to resonance by condensers 26, 36 respectively. The voltage developed across the coils, which is taken as a measure of the Q value, is fed to the grid of a valve 40 arranged as an infinite impedance detector and having a variable resistance 42 and micro-ammeter M in the cathode lead. A negative bias for the grid of valve 40 is taken from the grid leak 17 of the oscillator and fed through a large resistance 46. With this arrangement, only the voltage above a certain predetermined minimum is measured, thus permitting the use of a very sensitive meter M. Also, if the bias is removed by failure of the oscillator, the meter is safeguarded by resistance 42. The comparison is made by switching 31 from 34 to 35 and comparing the readings of M. Another method is to replace one of the coils by a coil of known Q value and vary the coupling at 54 to give an arbitrary reading of the meter M, the scale of condenser 54 being suitably marked. Other coils of known Q are then substituted and the scale of 54 is again marked when the meter reading has been brought to the same value. In this way the scale of 54 is calibrated to read directly in Q values for a given reading of meter M. In a modification, Fig. 2 (not shown), the switch 31 is arranged to switch two condensers alternately in parallel with a fixed inductance to which the output of the oscillator is inductively coupled. The condensers are identical when air is the dielectric. Hence, by filling one or both of the condensers with samples of dielectric material to be tested, and comparing the resonant voltages attained, the dielectric properties may be compared.
