Abstract: 150,668. Ribis, G., and Beaufort, H. Aug. 30, 1919, [Convention date]. Spray carburettors.-A choke tube c, Fig. 1, for a spray carburettor comprises a lower cylindrical portion closed at its base by a plate f, and an upper taperng enlargement, the cylindrical portion surrounding a co-axial fuel nozzle e and being provided with air inlets d at the level of the nozzle orifice. In a modification. the annular passage between the bottom of the choke tube and the body of the carburettor is closed by a partition, and air inlets are provided in the side of the carburettor body. In a further modification, the choke tube contains a sliding piston valve f<2>, Fig. 3, having a central tube h surrounding the nozzle. The tube h is provided with apertures i, and the bottom f of the choke tube with apertures j. The valve f<2> is operated by a lever l which may be coupled with the throttle valve k. When the throttle is closed, the valve f<2> is raised until it abuts against shoulders g on the choke tube and closes the air inlets d, but is lowered as the throttle is opened. At slight throttle openings air enters through the apertures j, i and tube h only, but as the valve is lowered the air inlets d are gradually uncovered, and finally, the apertures j are closed.

Title: Improvements in and relating to the reduction of aromatic nitro compounds
Filed: 1926-04-21
Abstract: 274,562. Carpmael, W., (I. G. Farbenindustrie Akt.-Ges.). April 21, 1926. Amino compounds; aniline; alpha-naphthylamine aminosulphonic acids.-The reduction of aromatic nitro-compounds to the corresponding aminocompounds is carried out with iron and an acidreacting concentrated aqueous solution of an easily soluble salt of a metal more electropositive than iron, whereby the iron is converted into a finely divided oxide suitable for use as a pigment. The acid-reacting salt solution is obtained by acidifying an aqueous solution of the salt with a mineral acid which is not in itself a reducing agent, or by dissolving the salt in such acid; alternatively, it is obtained by hydrolyzin, the salt of a metal more electropositive than iron and of an acid not in itself a reducing agent. Suitable salts are the chlorides of the alkali and alkaline earth metals, magnesium, and zinc, and ferrous chloride also may be employed, but the use of aluminium salts, as described in Specification 263,376, is excluded. According to the examples, (1) nitrobenzene is reduced with iron and a solution of common salt or calcium chloride acidified with hydrochloric acid; (2) nitrobenzene is reduced with iron and a solution of ferrous chloride: (3) alpha-nitronaphthalene is reduced with iron and a solution of magnesium chloride acidified with hydrochloric acid. Reference is made also to the reduction of chlor-, oxy-, amino-, and polynitro compounds and nitrosulphonic acids. Specifications 12680/02 and 155,319 also are referred to.

Abstract: 1,123,022. Control of D.C. motors. RANSOMES SIMS & JEFFERIES Ltd. 10 March, 1966 [12 March, 1965], No. 10608/65. Heading H2J. [Also in Division H3] In a system for controlling the speed of a D.C. motor 1, e.g. in a battery-electric vehicle, by varying the on/off ratio of a continuously pulsed thyristor 9, the thyristor is turned off by the discharge of a capacitor 27 through a second thyristor 29, the charge on the capacitor being reversed during the conduction of the first thyristor by the operation of a third thyristor 35. The sequence is as follows: (i) 29 is triggered to conduct until capacitor 27 reaches battery potential V; (ii) 9 is triggered, energizing motor 1 and connecting batteryve to capacitor +ve plate causing the other plate to go -V; (iii) 35 is triggered, discharging capacitor forwardly through 9 and an inductor 37, which recharges the capacitor in the reverse direction to about + 3V; (iv) 29 is again triggered and the capacitor discharges, cutting off 9, and then is recharged by the battery to repeat the sequence. Triggering is effected by a multivibrator 47 of adjustable frequency, but thyristor 35 may be triggered according to the charge on capacitor 27. In alternative circuits (Figs. 2, 3, not shown) the voltage on the capacitor is limited by battery tapping or a resistor in series with the inductor and in Fig. 4 (not shown) the inductor is replaced by a resistor, the inductance of the battery being utilized.

[Also in Division H2] A percussive arc welding system wherein two workpieces E1 E2 are to be welded together, the piece E2 being held in a fixed member and the piece E1 in a movable member S has the movement of the member S controlled by the solenoid windings W1, W2, the winding W1 being energized to initiate movement of the member S; and hence the electrode E1 towards the electrode E2 until a position is reached at which the potential between the pieces E1, E2 causes an arc to be struck therebetween, the arc current then flowing through the winding W2 so causing the member S to move rapidly to impact the piece E1 on the piece E2. Capacitors C1, C2 are maintained charged from an A.C. supply and operation of a push-button PB1 energizes relay RLY from the same supply to change the positions of contacts 1, 2; the movement of contact 2 taking place before that of contact 1.

[Class 38 (v)] A cross-blast, gas-blast switch is adapted for high voltages by minimizing the electrostatic stress in the arc-gap after arc-rupture, and hence the risk of reignition, by spacing the insulating walls of the arc-chamber from the movable contact rod or blade a distance in inches varying from KV/P to 1.5 KV/P, where KV is the circuit kilovoltage and P the blast-pressure in lbs./in.<SP>2</SP>. As applied to the switch disclosed in Specification 544,017, in which the blast entering at 6 forces the arc against the edges of transverse insulating barriers in a diverging arc-chute 7, when the moving blade 2 is withdrawn from the fixed contact, the clearance of the blade 2 from walls 17 of horn fibre is preferably 1.14 KV/P, the expression not being valid for kilovoltages below 22 and pressures below 50.
