Patent GB-173219-A (GB)
Abstract: 173,219. Krupp Akt.-Ges., F. Dec. 20, 1920, [Convention date]. Adding and subtracting apparatus; cash registers; printing totals and sub-totals.-In machines having a number of totalizers which mav be selectively engaged with the actuating-means for receiving an item or imparting a total to be printed, a toothed disc or other member common to all the totalizers is provided for each denomination and carries zero-defining pins or pawls. When the totals key a<1> is pushed in, the selected totalizer controls the setting of the differential actuators and consequently the type sectors, and when stopped in the zero position slightly moves the toothed discs and so locks the actuators. As shown in connection with a cash register, the item keys a<2> wnen depressed, raise, and are locked by the detent sector a' pivoted at a<3> and adapted to operate, through a bail b<2>, a machine-release lever B normally held by a spring-controlled pawl b<5> and blocking an arm b<8> on the main operating-shaft b<9>. The rocking of the bail through a bar K also prevents movement of the totals key. Each differential actuator D carries a bolt d<2> suspended by links d<3> and connected by a pin d<1> with a pawl d<6>. In the operation of the machine, a notched disc E rotates and by engaging the inner end of the bolt drives it together with its disc D until the pawl d<6> strikes the stem of the depressed key and forces the bolt forward to disengage the disc D from the driving disc E and to lock it with the fixed rack a'. When the totals key a' is pressed, an arm i<1> rocks a hollow shaft J surrounding an error-cancelling shaft and so, through arms i<2>, shifts discs G each provided with zero-determining pins g<2> one of which is thereby placed in the path of a pin h<12> on the corresponding numeral wheel of the selected totalizing counter H<9> of the series H<1> - - H". A pin g<3> on the disc G simultaneously raises the key detent sector a' to lock the amount bank and release a sliding-bar C which then slides to the rear to maintain the sector raised and liberates through the pin d', the bolt d<2>. The latter is thus freed from its zero position, and the disc D may then be turned. The rise of the sector a<4> and the movement of a link L connecting the arm i with the lever B have meanwhile released the machine for operation, and when this takes place the driving disc E turns the actuating disc D until the pin h<12> returns to zero and engages its pin g<2>. The disc G now shifts sufficiently to cam forward through a projection f<3>, Fig. 6, a slide F and so project the bolt d<2> into engagement with the rack a'. Instead of fixed jaws g<2>, the disc G may be provided with one-way pawls which always stand in the path of the pins h<12> and may be passed by them in the forward movements of the wheels.

Title: Process for the recovery of sulphur values from anhydrite
Inventor: WINWARD ANTHONY
IPC: C01B17/50
Filed: 1951-07-24
Abstract: In a process for the recovery of sulphur as sulphur dioxide from anhydrite by heating the anhydrite in the presence of carbon in an oxidizing atmosphere, at least a major proportion of the carbon is employed in the form of petroleum coke having a sulphur content of not less than 5 per cent by weight.  The heat for the reaction may be provided by the combustion of a carbonaceous fuel of petroleum origin which has a high sulphur content and the combustion gases mixed with the sulphur dioxide produced in the process.  The carbonaceous fuel may comprise petroleum coke, fuel oil or acid sludge.  Cement may be produced as a by-product in the process if clay is mixed with the anhydrite and petroleum coke.

Title: Improvements in and relating to packing machines
IPC: B65B57/06
Filed: 1959-05-22
Abstract: 879,440. Weighing apparatus. ARENCO A. B. May 22, 1959 [June 30, 1958], No. 17571/59. Class 143 [Also in Group XVII] In a machine for filling bags, a weighed hatch falls successively into a package from a conveyer thereby avoiding jamming in a hopper from which the hatch is usually fed. The package, which may be a bag, passes successively through stations I, II, III, and IV where it is opened; squared-up, sensed, and filled. A Geneva wheel 2 causes the package to move intermittently and is driven by an arm 3 and shafts 5, 7, the shaft 7 being driven from a continuously rotating shaft 9 by an electrically controlled clutch 8. Cam discs 21, 23 on the shaft 5 indicate the angular position of the arm 3 and control operation of the electric control means 15. The hatch to be weighed is fed to a pan 17 and when the pan contains the exact amount for one package contacts 19 close, a solenoid 20 dumps the hatch from the pan to a conveyer 18 on which it is delivered to station IV. The time taken for the conveyer 18 to deliver the hatch from the pan to the station IV is arranged to equal the time taken for a package to move from station III to station IV. The circuits are controlled manually by a switch 27. If the weighing is not completed when a package is at station III the drive to the Geneva wheel is interrupted. To ensure that a package is completely filled, the connection between shafts 5 and 9 is delayed by means of a condenser and, variable resistance controlling the relay of a switch in the circuit of the clutch solenoid 10. The variable resistance can be adjusted to alter the delay. Two weighing machines can be connected to one control mechanism 15. In an alternative construction photo-electric means may replace the discs 21, 23 and co-operating sensing members. Specification 563,968 is referred to.

Title: Process of and apparatus for the use of heavy oil in the manufacture of carburetted water gas
IPC: C10J1/213
Filed: 1930-06-06
Abstract: 345,577. Carburetted water gas. HUMPHREYS & GLASGOW, Ltd., Humglas House, Carlisle Place, London.-(Assignees of Perry, J. A.; Swarthmore, Pennsylvania, U.S.A.) June 6, 1930, No. 17583. Convention date, July 27, 1929. [Classes 55 (i) and 55 (ii).] The usual carburetted water gas set is modified by using as a carburetter, a chamber containing a shallow fuel bed which is blasted up at the same time as the generator fuel bed, heavy oil being supplied to the top of the carburetter during the run, and coke being deposited from the oil on the fuel bed which is subsequently heated by an air blast. The gas outlet is above the fuel bed so that reversal of flow takes place in the carburetter. During the blow with air from a pipe 6, the blast gases with secondary air from a pipe 11 pass through the carburetter 2 which has a shallow fuel bed 15, and by a conduit 18 to the superheater 3 and stack 22. During an up-run with steam from a pipe 7, the water gas is sprayed with heavy oil from a pipe 14, the oil being vaporized, and depositing coke on the fuel bed, the flow of the gases being suddenly changed before they pass by the conduit 18 to the superheater 3 and wash-box 4. This may be followed by a down-run with steam from pipe 8 or 9, the water gas passing through an outlet pipe 12 to storage, or to the carburetter. The coke deposited on the fuel bed 15 is burned in the subsequent blasting. A small amount of steam may be supplied through pipe 17 to the carburetter during the run. In a modification, the carburetter may be provided with a partition which divides the space above the fuel bed into two parts, this partition extending downwards to above the fuel bed and causing a sudden reversal of flow of the gases in the carburetter.

[Class 41] A cell 1 with rubber or similarly lined walls is provided with spaced electrodes 2 connected to a source of direct current, a plurality of spaced diaphragms 5 impervious to colloids, means to feed dilute aqueous suspension to the cell, means to collect concentrated suspension from the cell, and means to recycle a portion of moderately-concentrated suspension to the cell for further concentration. As shown, the dilute suspension is contained in a reservoir 6, from which it is fed to the cell by a pipe 7 and a manifold 10. The diaphragms 5 are spaced from the sides, top and bottom of the cell, except for the two rod diaphragms 5A, which extend to the sides and bottom. The diaphragms may be formed from a single sheet of material interlaced around vertical supports. When current is passed through the suspension, the colloid particles on their way to the anode are stopped by the diaphragms and fall to the bottom of the cell. The current is reversed periodically and prevents the colloids from coagulating on the diaphragms. The concentrate is led by a pipe 14 to a reservoir 11 from which a pipe 13 leads back to an injector 12 in the pipe 7 conveying suspension to the cell 1. Clear liquid is drawn from the cell through pipes 15 and foam caused by gases formed is withdrawn through suction pipes 16. The suspension may be polytetrafluoroethylene stabilized with-the sodium salt of the sulphuric acid ester of a mixture of long-chain alcohols, predominantly lauryl alcohol.
