Title: Improvements in imitation solid fuel fires
IPC: F24C7/00
Filed: 1939-01-18
Abstract: 523,938. Imitation solid-fuel fires. SMITH, F. H. Jan. 18, 1939, No. 1794. [Class 126] An imitation solidfuel fire comprises a plurality of imitation fuel elements made wholly or partially of heat-resisting glass such as is sold under the Registered Trade Marks " Pyrex " or "Phoenix " having heating means associated therewith and so spaced or apertured as to permit light to issue from the interior of one or more elements on to the exterior of other elements. The heating means may be electric resistance elements or gas or oil burners, and separate gas, oil, or electric illuminating means may. be provided to enhance the appearance of glowing fuel. The Figure shows an imitation fire comprising a base 1 carrying electric resistance heating elements 9 and tubular illuminating lamps 12 arranged below an imitation fire-bed 6 of heat-resisting glass. A number of irregularly surfaced fuel elements 7 of heat-resisting glass are secured overlapping one another above the fire-bed by wires 8 attached to the base 1. A reflector 15 and spinner 16 at the back of the fire produce a flickering effect. The elements 9 are also fitted with reflectors 11. The fuel elements may be coloured or treated to simulate fuel or logs in a burnt, unburnt, or partially burnt condition, and may be made in two or more pieces or formed integrally with the fire-bed. The fire-bed 6 may alternatively be made of fire-clay and be formed with apertures having heat-resisting glass insets through which the heating elements and lamps project. Colour filters or coloured lamps may be used to obtain desirable effects.

Title: Improvements in or relating to the purification of organic sulphonated compounds
Filed: 1940-01-30
Abstract: 538,375. Purifying salts of sulphonated organic compounds. COLGATE-PALMOLIVEPEET CO. Jan. 30. 1940, No. 1832. Convention date, Jan. 31, 1939. [Class 2 (iii)] In order to free aqueous solutions of salts of organic sulphonic acids and organic sulphuric acid esters from salts of inorganic acids, two layers are formed by the addition of a suitable quantity of dioxane, ethylene glycolmonoethylether, diethyleneglycolmonoethylether, monoglycerides, mono fatty acid esters of glycols, water soluble aliphatic ketones, isobutyric acid or ethyleneglycolmonoethyletheracetate. The upper layer, which is substantially free from salts of inorganic acids is removed. Products obtained by sulphonating fatty oils, mineral oils, glycerides, partial esters of polyglycerols, glycols and polyglycols, aromatic compounds, higher alcohols, olefines and coal tar distillates are mentioned as starting materials. In examples, acetone and dioxane are used as the solvents for effecting separation into two layers of the neutralized sulphonated compounds. The lower aqueous layer containing the inorganic sulphate may be again separated into two layers by the addition of more solvent, when further small quantities of organic sulphonated compound may be recovered. In some cases it is desirable to increase the quantity of inorganic salt present before effecting the purification. Salts of sulphonated compounds with organic bases such as mono- and triethanolamine may be purified by the above process. Specification 537,255 is referred to.

Title: Improvements in or relating to stabilised d.c. voltage supply networks
Inventor: WRIGHT PETER MAURICE
IPC: G05F1/52
Filed: 1954-01-21
Abstract: 761,087. Automatic voltage control systems. MARCONI'S WIRELESS TELEGRAPH CO., Ltd., and BUCKINGHAM, J. Jan. 11, 1955 [Jan. 21, 1954], No. 1843/54. Class 38 (4). In a D.C. voltage stabilizing network, of the type in which deviations of output voltage from a reference value control an amplifier valve whose output varies the resistance of a pentode in series with the network load, the pentode has its screen grid connected to the amplifier valve anode through a high dynamic impedance, its control grid directly connected to the amplifier anode, and its screen grid-cathode space connected to the cathode resistor of a third valve, whose control grid voltage is related to the network output. The pentode 2<SP>1</SP> has its screen and control grids connected to the anode of the amplifying pentode 5, in the former case through a pentode 12 and a resistor 13 forming a high dynamic impedance load for valve 5. The latter is in series with a neon 6 providing a reference voltage and has its control grid connected to a tapping on the output resistor 4. A steady screen voltage is provided across a neon 11. A triode 14, connected as a cathode follower with the screen grid-cathode space of pentode 21 as its cathode resistor, has its grid voltage derived from the potential-dividing network comprising resistors 15, 18 and neons 16, 17, resistor 18 being the cathode resistor of a second triode 19. This valve is connected as a cathode follower with its grid voltage derived from the positive output terminal. The pentode 12 has a steady screen voltage derived from neons 16, 17, and has its control grid connected to the anode of valve 5. The circuit allows adequate anode voltage for valve 5 without the necessity of a low impedance shunt path across valve 2<SP>1</SP>. The input impedance of the network is therefore high, and the output impedance low.
