Title: Fabric softening composition
IPC: D06M13/405
Filed: 1975-05-12
Abstract: 1483984 Fabric softener compositions AZOTE ET PRODUITS CHIMIQUES SA 12 May 1975 [6 June 1974] 19931/75 Heading D1P A fabric softening composition comprises the mixture of an imidazolinium salt I wherein R and R' which may be the same or different, are aliphatic hydrocarbon radicals of 12 to 20 carbon atoms the radicals being saturated or unsaturated, and linear or branched, and R 1  is an aliphatic hydrocarbon radical of 1 to 4 carbon atoms, and a diamidoamine salt II of formula: where R, R' and R 1  are as defined above and B is an acid. R and R' are exemplified as stearyl, oleyl and lauryl, R 1  as methyl and ethyl, A and B as chloride, sulphate, methylsulphate and ethyl sulphate. Preferably the composition contains 10 to 40% II and 60 to 90% I. I may be formed by condensation of fatty acids with diethylene triamine followed by cylisation and quaternisation and the diamidoamine salt II can be obtained from I by alkaline hydrolysis. Preferably however the mixture of I and II is prepared directly from diethylene triamine and a fatty acid or mixture of fatty acids (e.g. hydrogenated tallow acids) and heating at a time and temperature low enough to give incomplete cyclisation. The composition may be used as 1 % aqueous solution. The diamidoamine salt counteracts the hydrophobic character of the imidazolinium salt thereby decreasing yellowing and soiling of the softened fabrics. Fabrics of cotton, other natural fibres or synthetic fibres, or mixtures thereof may be treated.

Title: Improvements in submarine sound transmitting and receiving apparatus
IPC: G01S1/72
Filed: 1920-07-09
Abstract: 147,939. Signal Ges. March 10, 1917, [Convention date]. Subaqueous audible signals.-The diaphragm 1 in contact with the water is separated from the sound producing or detecting device by a flat gasfilled chamber 4 of very small volume. The invention is illustrated in connexion with receiving- apparatus of electro-magnetic type. In the arrangement shown in Fig. 1, the gas chamber 4 is contained between the large outer diaphragm 1 and the small inner diaphragm 3, and communicates through a controllable throttle passage 8 with a large chamber 10. The diaphragm 3 carries the armature 5 of the detecting magnet 6. The coupling between the diaphragms 1 and 3 is closer the smaller the volume of gas, and, if the throttle passage were blocked, would be closer for low frequencies than for high. The throttle passage, however, tends to release the pressure-pulsations in the chamber 4, and this tendency is greater the lower the frequency, so that the total result is to favour the transmission of a particular range of frequencies, and to discriminate against frequencies higher or lower. The throttle passage also has the advantage of equalizing the static pressure on the two sides of the diaphragm 3. The closeness of coupling may be varied by changing the size of the gas chamber, or the pressure of the gas, and means may be provided for controlling these adjustments, as well as that of the throttle passage, from a distance. The diaphragms 1 and 3 and the detector itself may have the same or different natural frequencies, or may be aperiodic, so that the receiver as a whole may have either one or two or more predominant frequencies. If the diaphragms 1 and 3 have different natural frequencies, their effective frequencies when coupled will depend on the closeness of the coupling, and can be varied by varying the coupling. The coupling may also be varied for the purpose of adjusting the damping relations, for example to balance the radiation damping effect of the diaphragm 1 and the detection damping effect of the diaphragm 3. The amplitude of vibration of the diaphragm 3 may be made greater or less than that of the diaphragm 1 by suitably proportioning their sizes. There may be two gas-chambers 4, 11, Fig. 2, contained between three diaphragms of progressively diminishing size. To diminish the loss of energy by gas-friction in the shallow peripheral portion a of the chamber 4, a gas of small internal friction, such as hydrogen or ammonia, may be employed; or the gas-chamber 17, Fig. 4, may be surrounded or backed by liquid 15, so that the radial movements due to the difference in size of the diaphragms 1 and 3 take place in the liquid and not in the gas. The invention is applicable to receivers of the microphone type and to transmitters.

Abstract: 1486034 Power plants with sulphur and steam cycles; turbines ELECTRICITE DE FRANCE (SERVICE NATIONAL) 15 May 1975 [18 June 1974] 20655/75 Headings F1Q and FIT [Also in Division G6] Liquid sulphur is vaporized by heat exchange with a primary heat source fluid whilst maintaining the fluid and sulphur vapour pressures in a heat exchanger 14 equal. The vaporized sulphur is expanded through a turbine 16 to produce mechanical work and condensed in a heat exchanger 17, wherein water is boiled and the resulting steam super-heated; the super-heated steam being expanded and condensed in a heat engine, preferably a steam turbine 18 and condenser 19. The sulphur and steam turbines 16, 18 may drive a common alternator 21. In Fig. 1 the primary heat source fluid is the secondary liquid sodium coolant of a nuclear reactor 10. The secondary coolant is pressurized to the same extent as the sulphur vapour in the heat exchanger 17 and receives heat from unpressurized liquid sodium primary reactor coolant in a heat exchanger 11. In Fig. 2, the primary heat source fluid is combustion gas from a fossil fuel generated in a furnace/sulphur boiler 22. A compressor 24 forces combustion air through a pre-heater 25 into the furnace/sulphur boiler 22 at a pressure equal to the pressure of the sulphur vapour generated. The combustion gases expand through a gas turbine 23 driving the compressor 24 and an alternator 26. The sulphur and steam cycles of Fig. 2 (not shown) are analogous to those in Fig. 1 in which an alternator 21 is driven. The gas turbine 23 may also drive the alternator 21, the alternator 26 being omitted. In addition, the plant may include (not shown) high and medium pressure steam turbines (on a common shaft with the sulphur vapour turbine), steam super-heaters and resuperheaters, sulphur pre-heaters, feedwater pre-heaters and further air pre-heaters, all these extra heaters being warmed by drains from the steam and sulphur turbines. To increase the peak load of the plant these drain-heated heaters may be shut down and extra air and fuel supplied to the furnace/boiler (22). The resulting extra combustion gas is directed to an ancillary or reserve turbine driving an alternator, without increasing the heat-transfer to the sulphur cycle.

A belt pulley 43 is loose on the. main shaft 11 of the machine, and a drum 27 is fixed to the shaft 11 and carries clutch shoes 42 adapted, on the depression of a treadle 64, to engage the pully 43 to start the drive. When the clutch is disconnected, a brake shoe 57 is simultaneously applied to the drum 27 to stop the machine. The clutch shoes 42 are carried by levers 42' pivoted at 45 to the drum 27 and having weighted ends 46 to which are connected springs 47 to hold the shoes normally out of contact with the pulley 43. The levers 42<1> are also connected to arms 36 pivoted at 37 to the drum 27 and adapted to be operated by rods 32, the ends of which engage recesses 25 in a collar 23 slidable on the shaft 11. The rods 32 actuate the arms 36 through springs 33 and loose washers 34. The sliding movement of the collar 23 is effected by turning a collar 20 having cam surfaces 21 engaging corresponding surfaces on a fixed member 16, and' the collar 20 is turned by a cable 65 connected to a disk 60 on the treadle actuated shaft 58. The disk 60 is held in adjusted position by friction against a standard 59. The brake shoe 57 is carried by a lever 49 pivoted at 52 to the press frame 10 and carrying a roller 54 held in engagement with a cam projection 55 on the collar 20 by means of a spring 56. On depressing the treadle 64, the collar 20 is turned and the cam 55 allows the spring 56 to release the brake 57. Simultaneously, the arms 36 are turned to move the clutch shoes 42 into engagement with the pulley 44. As the speed of the shaft 11 increases, the weighted ends 46 of the levers 42<1> tend to swing outwardly against the pressure of the springs 33 so as to disengage the shoes 42, and by this means the speed of the shaft 11 may be controlled.
