Abstract: 840,590. Automatic voltage-control systems. RACAL ENGINEERING Ltd. Nov. 23, 1956 [Nov. 23, 1955], No. 31331/59. Divided out of 838,058. Class 38 (4). Fig. 2 shows a circuit for modulating the output voltage from a stabilized power supply of conventional type in which the constant output voltage is adjusted by potentiometer R. The modulation signal is applied to the primary winding of a transformer whose secondary L2 is connected in the feedback loop of the stabilizer. It is shown while the high-tension voltage may be varied between wide limits the percentage depth of modulation is maintained substantially constant. The circuit which is stated to be of particular use for the modulation of radio-frequency oscillators enables the power output to be varied between wide limits whilst maintaining substantially constant the percentage modulation. The circuit may be used for modulating a carrier signal by intelligence or for applying a sinusoidal modulation to an oscillator used in a test signal generator.

Title: Manufacture of polymethine aldehydes
IPC: C09B23/02
Filed: 1936-11-19
Abstract: Unsaturated polymethine aldehydes are made by treating with an alkaline agent in presence of a solvent a dyestuff of the general formula <FORM:0485624/IV/1> wherein R1 and R3=aryl, R2 and R4 = alkyl or R1, R2 and R3, R4 may together form a simple or substituted ring system, X=any desired acid residue, e.g. halogen or an alkyl or aryl sulphonic acid residue and n=1, 3 or 4.  The aldehydes have the formula <FORM:0485624/IV/2> Corresponding dyestuffs substituted in the polymethine chain e.g. by halogen, alkyl or oxacyl, may also be used as starting materials in which case such substituent will also appear in the aldehyde chain.  The aldehydes can be used for the synthesis of polymethine dyes, thus those with three methine groups react with cyclic ammonium salts of heterocyclic bases containing a reactive CH3 group to form pentacarbocyanines, those with seven methine groups form nonacarbocyanines and those with nine methine groups form undecacarbocyanines.  They also react with amino compounds and with compounds containing reactive methyl or methylene groups.  In examples: (1) the dyestuff from tetrahydroquinoline, propargyl acetal and hydrochloric acid is dissolved in methanol, water and magnesium oxide are then added and superheated steam passed in; methanol and tetrahydroquinoline (1 mol.) distil in the steam and the residual aldehyde is extracted with ether or benzene, (2) the dyestuff <FORM:0485624/IV/3> (cf. Specification 485,623) is treated as in (1), (3) the dyestuff from furfuracrolein and tetrahydroquinoline (see Specification 441,624) is boiled with methanol, water and borax, (4) the acetylated dyestuff from monomethyl aniline (2 mols.) hydrogen bromide (1 mol.) and furfuryl-pentadienal (1 mol.) is boiled with methanol, water and magnesium oxide, (5) the dyestuff from dihydro-a -methylindol, propargyl acetal, hydrochloric acid and potassium iodide is treated as in (1) with sodium carbonate instead of magnesium oxide.

Filed: 1922-11-21
Abstract: 194,260. Eureka Metallurgical Co., (Assignees of Nokes, C. M.). March 4, 1922, [Convention date]. Flotation processes.-A flotation process of concentrating ores, particularly oxidized or non-sulphide ores, consists in intimately mixing addition agents, which assist the subsequent flotation action, before introducing them into the pulp of the ore. A pulverized alkaline sulphide, such as sodium sulphide, is made into a paste with a melted hyodrocarbon such as paraffin. This mixture is then broken into fragments or pulverized and introduced into a tube mill together with the ore to be ground into a pulp, or it may be introduced into the pulp after the ore has been ground and passed into an emulsifier. Another method of mixing consists in grinding the two ingredients together, heating them very highly, and then spraying the mixture into the pulp. Oils such as pine oils are added to expedite and improve the formation of a froth in the flotation cell.
