Filed: 1959-11-16
Abstract: 896,366. Centrifugal pumps. KLEIN, SCHANZLIN & BECKER A.G. Nov. 16, 1959, No. 38713/59. Class 110 (1). Cavitation bubbles formed at the inlet to a centrifugal pump impeller pass through auxiliary blades 6 instead of the main blades 5. A restriction 9 at the outlet of the blades 6 keeps the pressure at the blades 6 high enough to prevent the cavitation bubbles from collapsing (and thereby causing cavitation erosion) until they have passed into the delivery 8. In the embodiment shown, the blades 6 are united with the blades 5 radially inwardly of a partition 4, but beyond this common portion the blades 6 may be curved in the opposite direction to the blades 5 to assist in producing the required higher pressure. In a modification, the partition 4 extends radially inwardly to separate the blades 6 wholly from the blades 5. In addition to being of opposite curvature to the blades 5, the blades 6 are then preferably more numerous.

Abstract: 977,404. Digital electric calculating. INTERNATIONAL BUSINESS MACHINES CORPORATION. Nov. 2,1961 [Nov.29, 1960], No. 39211/ 61. Heading G4A. A decimal adder includes and gates each comprising a neon 26 and a photoconductive strip 30. If the neon 26 is lit by a voltage on the O terminal of the Y input, the impedance of strip 30 decreases and a high voltage at the O terminal of the X input will result in a high voltage on line 38. Fig. 2 shows the principle of construction of the decimal adder:one terminal from each of the X and Y inputs is marked with the result that one out of the three lines 38 to 42 is marked. The decimal embodiment is described with reference to Figs. 3 to 7 (not shown) and 8, and has 11 X-inputs and 10 Y-inputs; marking one from each set of inputs marks one out of twenty output lines. A trigger 110 (Fig. 8) operated by a timer 82 controls gates 102,104, 106,108: when the trigger is set, gates 104 and 106 are open, when unset, gates 102,108 are open. A signal on any of the adder output lines representing digits 0-9 marks line 74, on any of the lines representing numbers 10-19 marks line 72. Flipflop 98,100 are switched at alternate time intervals and in the intervening interval the setting of a flip-flop is gated to mark one of the in-carry or borrow lines 62,64 &c. Which line is marked depends on which of the true or complement neons 110,112 is lit, and this in turn depends the type of operation as indicated by the setting of switches 120,122, the signs of the operands entered on lines 116,118 and the relative magnitude of the numbers entered on switch 126. The sign of the result is indicated on lines 124-switch 127 must be appropriately set. An inverse operation can be called for by operating the modify switch 126. This switch must be closed before an add or subtract switch otherwise an error lamp 148 is lit.

A fuel filler stub 18 is sealed at 21 to the enlarged top 16 of the fuel pipe 13, and seals 17 between the inner most tube 13 and the enlarged head of sheathing tube 14 provide an insulating space. The head of sheathing tube 14 is sealed at 23 to the inside of a head 29 which is removably connected by flanges 30, 36 to the oxygen tube 24. A flange 38 intermediate the ends of the tube 24 serves to removably secure a sleeve 39 carrying a cooling water inlet connection, and an inter mediate flanged sleeve 43 sealed to an enlarged head 47 connected to an oxygen extrusion tube 24<SP>1</SP>. The head 47 is sealed to the oxygen tube 24, and a space 46 between the flange 38, the sleeve 43 and the oxygen tube 24 is vented by bores 46<SP>1</SP> in the flange of sleeve 43 to allow the escape of oxygen passing the seals 49, 50. A lower flange 53 on the water supply sleeve allows a cooling water outlet sleeve 57 carrying the outermost tube 57<SP>1</SP> of the lance and a tube 39<SP>1</SP> dividing the coolant flow and return passages to be removably connected to the lance supply head. The space 32 within the upper end of the head 29 is closed by cap 27, and is vented through screw-in plugs (Fig. 4) which can be removed to allow pressure testing. The insulating space surrounding the fuel pipe may be connected to the space 32 by bores by-passing the seals 17 so that leakage of oil into the insulating space is readily observed.
