Abstract: 1426783 Polyurethane foams RHONEPOULENC SA 20 July 1973 [20 July 1972] 34632/73 Headings C3R and C3S In a process for the preparation of "coldcured" flexible polyurethane foams by pouring a foamable composition into a mould, closing the mould, forming the foam and releasing it from the mould, the foamable composition contains 0À1 to 5% of its weight of an organosilicon compound of the general formula in which R<SP>1</SP> represents a hydrogen atom, a monovalent C 1 -C 8  hydrocarbon or C 1 -C 3  halohydrocarbon radical, T represents a hydrogen atom, a monovalent C 1 -C 15  hydrocarbon or C 1 -C 6  halohydrocarbon group, and a = 0, 1 or 2. The organosilicon compounds can be prepared by the cohydrolysis of organochlorosilanes optionally in the presence of an organic solvent. Preferably they are prepared by reacting the organochlorosilanes with C 4 -C 8  tertiary aliphatic alcohols alone or in admixture with C 1 -C 4  primary or secondary alcohols. In the examples numerous organosilicon compounds are prepared by reacting a mixture of chlorosilanes with tertiary amyl alcohol and isopropyl alcohol in the presence of toluene, and the resultant compounds are added to polyurethane foamable compositions comprising p,p<SP>1</SP>-diisocyanato-diphenylmethane, toluene diisocyanate, a polyether triol of M. wt. 4800, a polyether diol of M. wt. 800, dimethylcyclohexylamine, triethylenediamine, water and fluorotrichloromethane.

Abstract: 1,006,162. Measuring torque. UNITED AIRCRAFT CORPORATION. Sept. 3, 1963 [Sept. 7,1962], No. 34733/63. Heading G1W. [Also in Divisions B7 and F1 A gas turbine engine support and torque indicator arrangement comprises a rear mounting permitting rotation of the engine casing and a forward mounting supporting the engine, a lever on each side of the engine being pivotally attached at its inner end to the casing and at its outer end to an interconnected linkage system including a load measuring device measuring the movement of the outer end of the levers to determine the engine torque. The forward support of the right-hand engine of a pair of gas turbine engines mounted on a helicopter fuselage, comprises, Fig. 3, brackets 22, 24 attached to the engine casing. Levers 26, 27 are pivotally connected at their inner ends to brackets 22, 24, respectively, and are pivotally supported by links 28, 30 from brackets 32, 34, respectively, attached to the fuselage. Bell-cranks 40, 50 are pivoted to the brackets 32, 34 and connected by a link 60. The horizontal arms 42, 52 of the bell-cranks are connected by links 46, 56 to the radially outer ends of levers 26, 27, respectively. Bracket 34 carries a track 79, Fig. 4, for a load measuring device 80 incorporating a damper of alternate rubber and metal plates 86, 88. The device 80 is pivoted to crank 52 by an adjustable link 90. The forward support structure is located in the vertical fore and aft plane by a link 62 and ball joints are incorporated in appropriate pivots to permit axial movement of the engine casing. The rear mounting of the right-hand engine, Fig. 7 (not shown), comprises an extension of the exhaust gas deflector containing a spherical seating cooperating with a ball fixed to the fuselage. The rear mounting locates the engine axially and radially but permits rotation of the casing thereof. Rotation of the engine casing as the result of an output torque T, Fig. 3, causes the forward mounting linkage to transmit a force to the measuring device 80 which transmits an electrical signal proportional to the torque to an indicator in the pilot's cabin. The forward and rear mountings of the left-hand engine are substantially identical with those described.

Title: Improved process for evaporating liquids
IPC: C01D1/42
Filed: 1920-12-10
Abstract: 181,406. Bohrmann, L. H. A. Dec 10. 1920. Spray evaporators.-Liquid is evaporated from a liquid mixture of two or more constituents by spraying the mixture on to or beneath the surface of another liquid maintained at a temperature considerably above the temperature of the mixture, and above the boiling-point of the constituent to be evaporated. The liquid on to or into which the mixture is sprayed must be one with which the mixture is miscible to form a solution or suspension. In an apparatus suitable for concentrating dilute caustic soda solution, the dilute liquor flows from a tank A up a wide pipe C to a device D, by which it is sprayed on to the surface of hot concentrated caustic soda solution b in a tank E. The solution b is heated by a steam coil G and is kept in motion by a stirrer H. Steam passes away by a pipe J, thus preheating the dilute solution flowing up the pipe C. Concentrated caustic soda solution passes away continuously by a pipe O, also arranged to preheat the incoming dilute solution. Saline solutions may be sprayed on to hot oil, and the crystallized salt collected from the bottom of the tank E. Dilute sulphuric acid may be con centrated by spraying it on to hot concentrated sulphuric acid.

The carrier has also a pair of wheels E, E<1> which gear respectively with one of a pair of change-speed wheels G, G<1> loose on the spindle B and carried by the hub of a disc H which controls the gas supply valve. By axial movement of the disc H, the wheels E<1>, G<1> or E, G may be brought into mesh according to the coin to be used. The disc H is locked in either position by an arm 5 operated by a lever 7 which prevents the cover from being fitted in position unless the arm 5 is depressed.
