Abstract: Compositions for use in the production of air foams for fire extinguishing purposes comprise water soluble salts of aliphatic amines having an aliphatic side chain of more than ten carbon atoms connected with the nitrogen atom.  Amine salts suitable for the purpose are dodecyl - dimethyl amine formate, benzyldimethyl-dodecyl-ammonium chloride, betaines having an aliphatic radical with more than 10 C. atoms attached to nitrogen, e.g. dodecyldimethyl-betaine, or corresponding phenolbetaines from N-methyl-dodecyl-amino-phenols, salts of compounds with two or more aliphatic amino groups of high molecular weights, salts of the substituted di- and poly-amines, e.g. of N - N<1>-dodecyl - methyl - ethylene - diamine, and of mixtures of amines from commercial fatty acids, e.g. amines obtained by the reduction of nitriles from fatty acids of palm nut oil, cocos oil, or train oil.  Examples of compositions for admixture with water are: (1) a mixture of dodecyl dimethyl amine, acetic acid, alcohol and water; (2) a primary amine obtained from palm oil fatty acid is treated with methylchloride till neutral and the product is mixed with a solid albumen hydrolysate with the addition of water, alcohol and glycol.

Abstract: 552,569. Coating ferrous metals. PYRENE CO., Ltd. (Parker Rust-Proof Co.). Oct. 6, 1941, No. 12907. [Class 82 (ii)] In a method of coating ferrous metal surfaces by means of a solution of a phosphate that is non-oxidizable by permanganate, e.g. zinc dihydrogen phosphate, and in which permanganate is used as an oxidizing agent, the MnO 4  content of the solution is maintained between 0.0005 and 0.005 per cent. and the pH value of the solution is maintained above equilibrium by an amount from 0.12-0.38. When zinc phosphate is used, the zinc content is 0.1- 0.5 per cent. of the solution, which may be sprayed on the surface. The phosphates of cadmium and the alkaline earth metals may be used instead of zinc and the coated surface is rinsed with a dilute solution of chromic acid or a dichromate. A replenishing solution contains an acid zinc phosphate and permanganate in such proportions that the zinc content is from 3.5-15; preferably 3.5-7 times as much as the MnO 4  by weight. In an example a solution contains zinc, phosphoric acid and permanganate, the acid being in such an amount as to provide ¥ i pound H,PO, per 6.7-7 pounds of Zn (H 2 PO 4 ) 2  2H 2 O, and there being 3.5-7 times as much Zn as MnO 4  in the solution by weight.

Receiving audible signals; subaqueous audible signals.-An electromagnetic vibrator for transmitting or receiving sound signals comprises two rigid members 1, 2, Fig. 5, connected by elastic members 8 which are connected at their extremities by rigid strengthening members, the masses 8 carrying magnetic pole pieces 10 associated with an exciting coil 12. The magnetic circuit may be polarized permanently or, as shown, electromagnetically through the exciting coil 12 by means of a direct-current source 15. Excitation may be by means of an oscillating valve, the oscillatory circuit of which is coupled through a transformer to the coil 12. The masses 1, 2 may be solid, or hollow with strengthening ribs. Figs. 7, 8 show a construction, adapted to be suspended vertically, in which rigidity is obtained by a number of ribs 2, and the coil 12 is mounted in association with the pole-pieces 24 by flexible rods 25. In another construction, one only of the rigid members vibrates, the other being mounted on a large supporting block. In further constructions, the vibrator is coupled to another vibrator of similar type but of larger dimensions or to a diaphragm. When the vibrator is used in a medium such as water it is enclosed in a casing having one side thin and deformable, the casing being filled with an insulating fluid.

Title: Improvements in or relating to calorimeters for measuring the amount of heat given out or absorbed by a flowing medium
IPC: G01K17/14
Filed: 1953-05-13
Abstract: 732,872. Calorimeters. KOOIMON, P. L. [trading as HANDELMAATSCHAPPIJ AVEDKO C. V.]. May 13, 1953 [May 20, 1952], No. 13392/53. Class 97 (3). In a calorimeter for measuring the amount of heat given out or absorbed by a flowing medium, comprising a flow meter which drives a counting mechanism and two Bourdon tube thermometers, the latter are mounted side by side about a differential gear, and the movement of each spiral is transmitted to the corresponding crown wheel of the differential gear by a coupling rod, the third gear of the differential being rotatable on a pin keyed to the differential shaft, the movements of the latter being transmitted 'to the counting mechanism by a lever arm. As shown, the movements of the spirals 7, 8 of the Bourdon tube thermometers are transmitted to the crown wheels 21, 22 by connecting rods 13, 14 which are adjustable on the tubes and radially slidable in the hubs of the crown wheels. The axis of the pinion 23 is secured at right angles onto the shaft 6 about which the crown wheels are freely rotatable. The movements of the spirals cause rotation of the pinion about the axis 6, and this rotation is imparted to the lever arm 27, secured to the axis 6. The movement of the lever arm 27 causes the disc 33, keyed to shaft 34 to slide along this shaft. The speed of rotation of the disc 33 is varied by virtue of the position of its point of contact on the surface of the cone 38, driven by the flow meter 50. The speed of the wheel 44 of the counting mechanism thus depends on the position of the lever 27 and the speed of revolution of the cone 38, the speed of the latter being controlled by the flow meter and imparted to the counting mechanism by gear 45.

The polyethylene forms 0À25 to 5À0% by wt. of the solution. If a propylene copolymer is used it comprises 90 to 98% propylene and 10 to 2% ethylene.

Abstract: 348,367. Metallic-vapour rectifiers. LAMM, U. and ALL MANNA SVENSKA ELEKTRISKA AKTIEBOLAGET, Vasteras, Sweden. May 6, 1930, No. 13902. [Class 39 (i).] In the cooling of an anode of a metallic-vapour rectifier by means of a liquid such as mercury, which is vaporized inside the anode and is condensed in a chamber situated outside the rectifier, the vapour passage between the anode and the chamber is surrounded with heat insulation to protect the vacuum-tight joint and also the anode insulator and its packing. An anode 2, of pure iron, has a tubular extension 3 which is housed within an insulator 11, and is sealed by means of packing 13 within a packing box 12. A vapour passage 5 is surrounded by heat insulation 4. An inert gas or hydrogen may be enclosed within the anode to maintain constant the boiling-point of the mercury. A nozzle 7 on the tube 5 acts, in conjunction with a tube 8, as a jet which ensures that a mixture of vapour and gas flows through the tube 8 and through the annular condensing chamber formed by the tube 8 and the extension 3. Cooling fins 9 are provided. Condensed mercury returns to the anode through a pipe 6, the lower end of which is bent to form a liquid seal. In a modification, Fig. 2 (not shown), the anode extension 3 is extended past the cooling fins to form a reservoir for the gas, which is thus prevented from impeding the flow of vapour to the walls of the condensing chamber.
