They may be obtained by (a) coupling an aromatic diazo, tetrazo- or diazoazo compound with a coupling component, at least one of the components containing at least one group of the above formula, and treating the azo dyestuffs thus obtained with metal yielding agents provided the dyestuffs contain substituents capable of forming complex metal compounds or convertible into such a substituent in the o-position to the azo group; or (b) reacting azo dyestuffs or their complex metal compounds which contain at least one group of the formula <FORM:1112394/C4-C5/2> with salts of thiosulphuric acid at pH values from 3 to 8 approximately.  Specified metal complexes are Cu, Co, Ni or Cr complexes. Examples are given for the production of the dyes. They may be used for dyeing or printing natural and synthetic fibre materials.  The dye of the formula <FORM:1112394/C4-C5/3> is obtained by condensing 2-amino-5-hydroxy-naphthalene - 7 - sulphonic acid with 4 - (N-methyl -vinylsulphonylamino) - benzene - 1 - carboxylic acid chloride and coupling with diazotized 1 - methoxy - 4 - aminobenzene - 3 - sulphonic acid.

Title: Control device for a headlight system
IPC: B60Q1/14
Filed: 1960-10-05
Abstract: 901,728. Photo-electric headlamps; dimming. INTERNATIONAL POLAROID CORPORATION. Oct. 5, 1960 [Oct. 30, 1959], No. 34162/60. Class 40 (3). [Also in Group XL (c)] Vehicle headlamps are dipped by apparatus responsive to dipping or raising of oncoming headlamp beams. Sudden variations in the output of a photo-cell 12 are differentiated by a capacitor 22 and resistor 28 and applied to a triode 26. The resulting positive pulse appearing on the anode 30 or the cathode 34 triggers a thyratron 46. If the illumination on cell 12 is sufficient, the bias it supplies to the grid 90 is sufficient for the thyratron cathode pulse to cause triode 82 to conduct, thus energizing the relay 60. Relay 60 dips the headlamps, closes contacts 68, 70 and opens contacts 66, 68 to maintain triode 82 conducting and to cut off thyratron 46. When the oncoming vehicle has passed, the cell illumination falls and triode 82 cuts off. Relay 60 drops out to restore the headlamps to high beam. Capacitor 92 delays this slightly to prevent response to short interruptions of the cell illumination. If the system is used with headlamps and a driver's protective visor-like polarized at 45 degrees to the vertical, a filter in front of cell 12 may be similarly polarized to ignore the lights of a similarly equipped car. The thermionic tubes may be replaced by semi-conductors.

The catalyst components are preferably supplied to the polymerization batch separately and dissolved in inert diluents. Alternatively mixtures of the above ethylene copolymers can be obtained by (a) separating copolymers of conventional molecular weight distribution into fractions of different molecular weight by fractional solution and/or precipitation and then mixing the fractions so that the desired molecular weight distribution is achieved, (b) dissolving out from copolymers of conventional molecular weight distribution certain fractions so that after removal of these fractions the required molecular weight distribution is obtained or (c) mixing suitable polymers in the solid state on rubber-processing machines or by common precipitation of partial solutions or partial dispersions which have been prepared separately.  In making the copolymers of the invention 1 to 30% of 1,5-hexadiene, butadiene, isoprene, dicyclopentadiene and other polymerizable polyenes can be copolymerized with the olefine comonomers.  Lists of fillers and plasticizers which may be added are given.  In the example an ethylene/propylene copolymer is prepared using as catalyst aluminium ethyl sesquichloride and VOCl3 and the copolymer is then vulcanized by heating with HAF carbon black, dieumyl peroxide and sulphur.

Abstract: 360,682. Counting-apparatus. LANDIS ET GYR, SOC. ANON., 1, Hofstrasse, Zug, Switzerland. Nov. 18, 1930, No. 34666. Convention date, Nov. 30, 1929. [Class 106 (i).] The indications of a number of meters are summed at a distance by means of a series of differential gears tending to rotate but only permitted to do so by arrival of impulses from the meters. As shown, a shaft 1 is adapted to be driven by a motor 27, 28 but is normally held by the arrangement of differential gears comprising planet wheels 9, 10 .. and sun wheels 2, 3 .. of which the first, 2, is fixed to the shaft 1 and the last 8 is secured to the bracket 17. The planet wheel carriers are loosely mounted on the shaft, are weighted at 20, and have lugs 21 normally held by a projection 36 carried by the spring-controlled armature 37 of a relay 31. An impulse due to the completion of a measurement at the meter is sent by the momentary closure of contacts 49, 50 and this rocks the corresponding armature to release its planet wheel carrier. Due to the weight the latter thereupon descends below the projection 31 and the drive from the motor causes a complete rotation of the carrier and therefore also of the shaft 1, this movement being counted by the train 25 and counter 26. If it is desired to count the impulses received from any individual meter, the associated planet-wheel may be mounted in a gear wheel such as 22 in train with a counter 24. Instead of arranging the shaft 1 horizontally it may be vertical and spring catches provided at the points 21, 36 to effect immediate release of the planet-wheel carriers by the impulses received and to prevent backward separation of the catches.

Abstract: 1476629 Fuel injection pumps CAV Ltd 10 July 1974 [20 July 1973] 34694/73 Heading F1A In a rotary distributer type fuel injection pump, the quantity of fuel delivered to a respective outlet port 17 during the inward pumping strokes of plungers 12 is controlled by a spill valve 23 mounted in the distributer member 11, the spill valve 23 being operated by a cam ring 27 adjustably mounted in the pump body 10. Fuel displaced by the plungers 12 flows to the outlet ports 17 through passages 15, 16, the pressure in the passage 15 acting on a plunger 25 to seat the valve's head 24 until the plunger 25 is moved radially inwardly by the cam ring 27. Angular adjustment of the ring 27 is caused by axial displacement of a member 30, the latter having an inclined slot (29), Fig. 2 (not shown) which receives a peg 28 on the ring 27. The member 30 is slidable in a bore in a timing control ring 14 having lobes for reciprocating the plungers 12 and a fluid operated piston 21 for adjusting its angular position. Thus angular adjustment of the timing ring 14 also adjusts the quantity control cam ring 27. A spring 31 urges the member 30 towards the maximum delivery position, a lever 35 pivoted at 36 being acted upon by the sleeve 34 of a speed responsive device 32 to adjust the member 30. A further spring (not shown) acts on the lever 35 with a force dependent on the position of an operator controlled member, the operator thereby controlling the amount of fuel delivered.
