Title: New optical bleaching agents and processes for the preparation thereof
Inventor: RENE MAURICE HENRI VANIER DE S
Filed: 1956-06-21
Abstract: The invention comprises optical bleaching agents of the formula <FORM:0830613/IV (b)/1> where M is a monovalent cation, Z is halogen hydroxy or amino and Y is a group <FORM:0830613/IV (b)/2> in which Z and Z1 are halogen, hydroxy, amino or substituted amino.  The symmetrical compounds can be made by condensing cyanuric chloride or bromide in either order with 4 : 41-diaminostilbene - 2 : 21 - disulphonic acid and with an amine HO-alkylene-HN-CH2COOM and, if desired, replacing one halogen on each nucleus by hydroxyl or amino. Another method, which can also be used to obtain unsymmetrical compounds, is to condense 4-amino - 41 - nitrostilbene - 2 : 21 - disulphonic acid with cyanuric halide, replace one halogen atom by reaction with HO-alkylene-HN-CH2COOM (and, if desired, the other by hydroxyl or amino), reduce the nitro group to amino, condense with a further molecule of cyanuric halide, and introduce the groups Z and Z1 if desired.  In examples, 4 : 41-diaminostilbene - 2 : 21 - disulphonic acid is condensed with 2 mols. of cyanuric chloride and then with 2 mols. of N-hydroxyethyl-glycine, the product being obtained as the trisodium salt; further reaction with sodium carbonate, ammonia or ethanolamine replaces two chlorine atoms by hydroxyl, amino or ethanolamino respectively.ALSO:Optical bleaching agents of the formula <FORM:0830613/IV(c)/1> where M is a monovalent cation (especially an alkali metal), Z is halogen, hydroxy or amino and Y is a group <FORM:0830613/IV(c)/2> in which Z and Z1 are halogen, hydroxy, amino or substituted amino, are applied in aqueous solution to textile fibres, e.g. of cotton, regenerated cellulose or nylon or to paper, straw, hides or plastic films.  Various compounds are mentioned.

Abstract: 391,150. Clocks. SCHNEIDER, F., 12, Brauhausstrasse, Fulda, Germany. Oct. 17, 1931, No. 19277/32. Divided on 380,628. [Class 139.] The circuit of an electric motor for driving the striking gear is closed at two separate rubbing contacts, one between the usual gathering pin and the rack teeth, and the other between the disc carrying this pin and an angle lever. At each hour a pin 3 on the minute wheel 2 engages a lever 6 pivoted at 8 to a drop lever 5 which thereby rotates about its pivot 7. A pin 60 on an arm 62 of lever 5 rocks a rack catch 55, 56 about a pivot 55<1>, a pawl 54 on arm 56 thereof releasing the rack 51, 89 pivoted at 88, which falls until its arm 61 engages the usual hour snail (not shown). As the pin 3 passes the end of lever 6, the drop lever 5 falls and depresses the arm 10 of a bell crank 10, 21 against a stop 12. A pin 17 on an arm 80 is thereby released from notch 21, and the angle lever 80, 84 pivoted at 19, is rocked by a spring 81, the arm 84 engaging the edge of an insulated disc 63 to close the motor circuit by way of 84, 63, insulated brush 71, 72, motor 79, 76, 77, 78, plate 1, 19, 84. The disc 63 is rotated by the motor, the gathering pin 68 thereon closing a further circuit to the motor as it engages the teeth of rack 89 which it lifts step by step in the usual way. A further pin 67 on the rear of disc 63 engages the arm 56 of the rack catch to lift the pawl 54 from the rack teeth 51 as the pin 68 is lifting a rack tooth 89 to prevent undue rubbing of the pawl. As the pin 68 engages the last rack tooth, a roller 91 on arm 90 engages a nose 83 on arm 84, thereby breaking the contact between the latter and disc 63, and returns the lever 80, 84 against the action of spring 81 until the pin 17 thereon is held by the notch 21, the second circuit of the motor being broken as the pin 68 leaves the last rack tooth. A pin 4 on the disc 2 is provided to strike the half hours, the catch 55, 56 being lifted by the arm 62 only sufficiently to release one tooth of the rack to give one strike.

Gas discharge apparatus for producing thermonuclear reactions comprises a toroidal vessel for containing a gas, electromagnetic means for causing a magnetic wave to travel unidirectionally around the vessel in the gas to induce transverse rings of current in it, the rings being dragged along by the wave to constitute direct current, the magnetic field of which tends to contain the gas independlenty of the vessel, and means for stabilising the path of the current. In Fig. 2, the quartz torus 1 is surrounded by eight coils 2 suitably connected to ring mains 16, 17, 18 carrying a 20 Mcs/sec. supply so that a travelling wave system flows round the torus ; the ring mains are hollow and also serve to feed cooling water to the coils 2 which are also hollow. The torus is mounted in an aluminium trough 6 through which cooling water is circulated via inlet and outlet pipes 7, 8. Four multi-turn field coils 24 are provided within the trough 6 to stabilise the discharge ; the coils are designed to carry 50,000 ampere turns flowing in the opposite direction to the ring discharge so that the net current flow over a cross-section is substantially zero, and the number of turns on the inner coils is different from those on the outer coils so that a curved field similar to a betation guide field is obtained. The torus is provided with a gas inlet 11 and outlet 12 and may be mounted beneath a thick aluminium shield 10, and the whole may be arranged inside a concrete biological shield, Fig. 3 (not shown). In operation the torus is filled with deuterium at a pressure of about 10-<SP>2</SP> mm. of mercury and the A.C. supply switched on at low power to initiate a low power discharge; the power is then increased and the pressure reduced to 10-<SP>5</SP> mm., the D.C. stabilising current being increased in step with the ring discharge current which reaches about 50,000 amps. Specification 839,247 is referred to.
