Title: Improvements in centrifugal pumps
IPC: F04D29/14
Filed: 1956-06-05
Abstract: 800,549. Centrifugal pumps; stuffing-box substitutes. BUNGARTZ, P.. June 5, 1956 [Nov. 11, 1955], No. 17297/56. Class 110 (1) and 122 (5). In a centrifugal pump of the type in which the shaft clearance is sealed by an auxiliary impeller when the pump is running and by a mechanical seal when the pump is stationary, the mechanical seal being opened by an axial movement of the shaft when the pump is running, the mechanical seal can move axially relative to the shaft under the action of a spring force. Centrifugal weights 21, Fig. 1, move the shaft 8 against the action of a spring 7 when the pump is running to bring the impeller 6 out of engagement with the surface 1 of a seal 2, which then bears instead against a shoulder 4 of the pump casing. The spring 3 of the seal is of bellows form and is weaker than the spring 7. When the pump is running, leakage is prevented by an auxiliary impeller 5. In a modification, Fig. 2, the seal comprises a diaphragm 9 and a flexible sealing disc 10 which is pressed by a spring 11 against a sealing surface 13 on the casing when the pump is stationary and against a shoulder 12 on the shaft when the pump is running. The lower half of Fig. 2 shows a further modification, in which the seal comprises a springy diaphragm 14. The axial displacement of the shaft may be adjusted by means of a nut 20, Fig. 1, and the bearing housing 17 may be threaded externally to permit adjustment of the axial position of the impeller.

Title: Improvements in cigarette making machines
IPC: A24C5/52
Filed: 1931-06-17
Abstract: 389,499. Cigarette-making machines. LUBBOCK, 1., 14, Green Lane, Hendon, London. June 17, 1931, No. 17564. [Class 130.] Lengths of filter-tip material are deposited upon a travelling paper strip at spaced intervals, and tobacco is prevented from being deposited on the parts of the paper strip where the filter material is placed, or tobacco is removed from such parts of the strip before the filter tip is deposited on it. In the construction shown in Figs. 1 and 2 the filter-tip material 7 is fed forward intermittently by rollers 9, and a portion is severed by a knife 10 and, after being pasted along its underside, is pressed upon the paper 5 by an endless belt 15 and rollers 16, 20. A slotted tube guides the tip from the rollers 9 to the belt 15. An endless belt 21, formed with slots 26 through which tobacco falls on to the paper 5, and with parts 27 between the slots which prevent the deposition of the tobacco on the paper at the positions where the filter tips lie on the paper, is driven by a sprocket wheel 22 at the same speed as the paper, beneath the outlet of the feeding hopper 1. The paper is then passed under a compression wheel 2, and through a former 3 to a cutting mechanism 4. The tobacco intercepted by the parts 27 is removed from the belt 21 by an inclined blade 28 or a revolving brush 29, and is deposited in a receptacle 30. A movable blade 31 placed beneath the band 21 prevents any intercepted tobacco from falling through the slots 26 and shears any loose tobacco strands. In a modification, the lengths of filter tip are deposited in spaces left in the tobacco on the paper 5. In the construction shown in Figs. 5 and 6, tobacco is continuously deposited on the paper 5 from the hopper 1, and at spaced intervals tobacco is removed from the strip and a filter tip deposited in the space left. A carriage 32 is reciprocated on a stationary member 33 by a cam and moves parallel with the paper strip. A slide 38 mounted on the carriage 32 carries a pin 39 which engages in a slot 40 in the member 33, so that the slide during the reciprocating movement of the carriage is reciprocated laterally. An extension 41 on the slide carries a spindle 43 on which is a brush 44, which at spaced intervals sweeps the tobacco off the paper strip 5. Discs 45 on the spindle 43 carry crank pins 46 which, by engaging stops 48, turn the brush through 90‹, so that on the return movement of the slide, the brush will clear the tobacco on the paper strip. At the end of the return movement of the slide, stops 49 engage the crank pins 46 and return the brush to its former position. The extension 41 carries flanges 53 which form an open trough behind the brush 44. The bottom of the trough is closed by a sliding plate 55 which, at the end of the forward movement of the slide 38, is withdrawn by a pin to deposit a length of filter tip on the paper strip 5. A spring 59 facilitates the deposition of the filter tip 12.

Abstract: 750,878. Control of motors. WESTING- HOUSE ELECTRIC INTERNATIONAL CO. June 16, 1954 [June 19, 1953], No. 17641/54. Class 38(3) A variable frequency alternator A supplies a number of squirrel cage induction motors, and is driven by a direct-current motor M having its armature 2 and field winding 15 energized through respective rectifiers R1, R2, connected to a three phase transformer T. A switch 3 connects the rectifier Rl to low or high voltage tappings in the secondary winding of the transformer, whilst a, rheostat 11 adjusts the excitation of the alternator field winding 12. The basic motor speed is selected by means of a rheostat 16 in series with the fielding winding ' 15, a cyclically varying component of motor field excitation being derived from transformer CT and induction regulator IG which are connected to rectifier 14 in the field winding circuit. A tapping 23 on a potentiometer 18 may be so adjusted that the resultant voltage at terminals 25, 26, is zero when the outputs of windings 21, 24 are in phase opposition. The rotor of the induction regulator is driven by a motor CM having its armature connected across a potentiometer 30, the voltage at terminals 25, 26, increasing from zero to a maximum and then decreasing to zero during one revolution of the rotor. The frequency of cyclic voltage variation may be adjusted by shifting tap 29, and its amplitude by adjusting tap 23. The motor M may have two field windings, one supplied at a fixed voltage from rectifier R2, and the other with an additive or subtractive variable component from the rectifier 14. The characteristic of the output of the induction regulator may be altered by means of a specially distributed winding on the regulator or special gear transmission for driving its rotor. The system may be applied to spinning machine drives.
