Title: Arrangement for displacing the ignition point of grid-controlled electric discharge vessels
IPC: H02H7/127
Filed: 1943-06-01
Abstract: 573,345. Converting. AKT.-GES. BROWN, BOVERI, & CIE. June 1, 1943, No. 8784. Convention date, May 23, 1942. [Class 38 (ii)] In a converter comprising a grid-controlled discharge device, the moment of ignition is varied under fault conditions by a D.C. voltage derived from a bridge circuit, one arm of which includes a magnetically controlled high vacuum electron tube 6, the control winding 9 of which is excited in accordance with the value (voltage or, as shown, current) to be controlled, The other arms of the bridge 1, 2, 3, 4 include resistances so proportioned that under normal conditions when current from a battery across points 1, 3 is flowing through the tube 6 no effective voltage appears across points 2, 4. Under fault conditions, and when the associated converter (not shown) is operating as an inverter, excess current in coil 9 stops the discharge in tube 6 causing a voltage to appear across points 2, 4 of such magnitude and polarity as to bias the grid of a valve 12 in such sense as to advance the phase of impulses produced in transformer 14, which impulses control the grid of the main discharge device (not shown). When the latter is operating as a rectifier, the connections to points 2, 4 on the bridge are interchanged so that under fault conditions the phase of the grid-control impulses for the main discharge device is retarded. Provision is made for maintaining the tube 6 in a blocked condition for a short time after coil 9 has functioned, such provision comprising a condenser 22 charged by an impulse transformer 20 through a rectifier 21, a leak resistance 23 being connected across the condenser.

The drum is driven by a gear wheel 5 and the quantity of feed is determined by the speed of the drum. Air enters through the spigot 7 and flows out through screens 25, casing 27 and outlet 28. With moist material hot air may be caused to flow in the reverse direction, the spigot 6 being provided with a screen. The mill may be modified to blend or grade material, the material being fed in at one or both ends and discharged by reversing the direction of rotation of the drum so that material enters pockets 23 and is discharged through openings 24 into a receptacle.
Patent GB-773423-A (GB)
Title: Improvements in or relating to method of producing alkaryl sulfonates
IPC: C07C309/31
Filed: 1955-03-25
Abstract: Alkyl aryl sulphonates substantially free from inorganic salts are prepared by reacting an alkaryl hydrocarbon with an amount of concentrated sulphuric acid or oleum under sulphonating conditions that the reaction product contains sulphuric acid of strength greater than 80 per cent by weight, diluting the resulting alkaryl sulphonic acid with such an amount of an inert hydrocarbon solvent that no phase separation occurs and the ratio of the hydrocarbon solvent to the original alkaryl hydrocarbon is at least 1.5 to 1 parts by weight, adding water thereto thus forming two layers, an upper organic layer comprising the alkaryl sulphonic acid, unsulphonated oil and the hydrocarbon solvent and a lower inorganic layer comprising sulphuric acid and water, the amount of added water being sufficient to reduce the concentration of the sulphuric acid in the lower inorganic layer to less than 80 per cent but not less than 75 per cent by weight, separating the organic layer, recovering the alkaryl sulphonic acid therefrom, neutralizing the sulphonic acid and then recovering the alkaryl sulphonate.  The separation of the sulphonic acid from the organic layer may be effected by distilling-off unchanged hydrocarbon and the solvent but preferably by extraction with an aqueous sotiluon of an aliphatic alcohol.  The resulting extract solution of the acid is neutralized with aqueous caustic solution or other base, e.g. an amine and the mixture evaporated to dryness.  In examples, dodecyl benzene is sulphonated with oleum and benzene and then water are added with stirring; the mixture is settled and the organic layer is separated from the lower layer of 77 per cent sulphuric acid, extracted with aqueous methanol, and the extract is neutralized with aqueous NaOH and dried. Specification 687,714 is referred to.

A paper feed roller 55 has projections 69 engaging central apertures in a paper receipt strip and a duplicate strip to draw them from feed rollers 66, 67, the duplicate strip passing to a take-up spool 56. The two strips pass over a roller 68 and under the type wheels 38 .. 44, ink ribbon passing between the receipt strip and the type wheels and between the two strips. The drawer is now closed and during the initial stage of closing the printing cam 48 engages the printing arm 50 and its tip 59 moves a printing roller 65, Fig. 7, into the dotted line position so that the roller passes successively under the paper strips beneath the type wheels 44 ... 38 and prints the number and date. During the final closing movement, a fixed ejector 57 forces the token 19 downwardly, the pivoted compartment 16 falls off the edge 13 and rotates by gravity about the pivot 17 to allow the bag with its token to fall into the vault. The downward movement of the token 19 rotates a feed arm 24 to turn the shaft 25 and cause a gear sector 53 to turn a pinion 54 clutched to the paper feed roll 55 to cause the printed receipt to be issued through a slot 75 in the front of the drawer, and the duplicate strip to be taken up on the spool 56. The receipt strip is perforated for easy detachment. Means are provided for restricting each rotation or the paper feed roll to that necessary to deliver one receipt. Racks and pawls are provided so that the drawer cannot be closed until it is fully open and cannot be opened until it has been fully closed.
