Title: Improvements in and relating to centrifugal pumps, fans and the like
IPC: F04D7/04
Filed: 1931-04-02
Abstract: 372,059. Centrifugal pumps &c. ALLEN & CO., Ltd., E., Imperial Steel Works, and BROADLEY, J. B., 91, Psalter Lane, both in Sheffield. April 2, 1931, No. 10074. [Class 110 (i).] In centrifugal pumps &c. of the kind in which the impeller blades a are formed with or held between two discs b, c, one or both of which have a central suction eye, centrifugal leakage is prevented by forming on the outer face of one or both discs b, c a packing ring e at or near the periphery and rotating on a ring f formed on the casing or on a fixed liner f<1>. A second. ring g runs on the inner face of the ring f. The disc c and/or the packing drum f may be provided with vanes h, i radiating from the suction eye to create centrifugal force between them. An auxiliary pump m fed with liquid by a pipe p prevents leakage into the stuffing-box k. In another form, the suction eye is formed in the disc remote from the stuffing-box, a second packing ring on the impeller disc coacts with a second ring on the sealing drum, and the latter is adjustable by means of a nut engaging a threaded boss on the drum. Specification 159,656, [Class 110 (i), Centrifugal and screw fans &c.], is referred to.

Title: Apparatus for assembling groups of articles
IPC: A24C5/47
Filed: 1962-03-16
Abstract: 1,002,582. Cigarette making machines. K. KÍRBER. March 16, 1962 [March 16, 1961], No. 10125/62. Heading A2C. In a cigarette making machine in which filter plugs are abutted with cigarette lengths and joined thereto by wrapping strips the absence of one of the components is detected and used to control the feed of one or both of the other two components. In the example shown, sextuple length filter plugs are fed from a magazine 1 to a take-off drum 4, are cut by cutters 5, re-aligned on wheels 6a, 6b, 6c so that three double length filter plugs are transferred to form a row in line ahead on a drum 8. From the drum 8 the filter plugs are transferred to a clutch-controlled grooved wheel 10, and thence to a conveyer 12 where they are joined by cigarettes on a cigarette magazine drum 14. Prior to the assembling of the cigarettes and filters, the presence of a cigarette is detected by a feeler device 22, which in the absence of a cigarette on the drum 14 causes an electromagnet 28 to de-clutch the wheel 10 and so stop the feed of filter plugs. The feeler may also cause a solenoid operated brake to be operated through a circuit 68 to stop the feed of the wrapper strip (Figs. 5 and 6, not shown). The clutch comprises a driving wheel 21 rotatable on a spindle 32 and mounted between walls 18 and 19. A flange 33 of the wheel 21 has two lugs 34 which engage an axially slidable clutch disc spaced by compression springs 36 from the flange 33. A hollow driving shaft 20 carries the grooved wheel 10, is rotatable on the spindle 32, and has a gear wheel 38 fastened to its tapered portion 37. The gear 38 has dogs 39 which engage between dogs of the clutch disc which is engaged by a thrust bearing 41. Transmission levers 42 are fastened to the end of the control shaft 30. When the electromagnet 28 is energized the control shaft is moved axially so that the levers 42 are pressed against the thrust bearing 41 which engages the clutch disc so that the dogs thereon are separated from the dogs 39 on the gear 38 and the feed of filter plugs is stopped. Braking is effected by a bell-crank lever 92, one arm of which carries a roller 93 which engages the flat part of the face of the clutch disc and the other arm of which carries a braking shoe 94 which engages a flange of the tapered portion 37 of the shaft 20.

Title: Improvements in mechanisms on lathes for the automatic insertion and withdrawal of chasers in thread cutting operations
IPC: B23Q1/68
Filed: 1969-02-26
Abstract: 1,223,381. Screw cutting lathes. SCHAUBLIN S.A. 26 Feb., 1969 [19 April, 1968], No. 10152/69. Heading B3T. Apparatus on a lathe for automatic feed and withdrawal of a chaser in thread-cutting operations comprises a transverse slide 5 guided on a member 4 on the lathe carriage, a chasing tool 25, 23, a tool support member 14 mounted on the slide 5 for displacement parallel to the direction of traverse of the lathe carriage, and means operable by the feed and return traverse of the carriage to withdraw the chaser and effect subsequent incremental feed thereof, respectively. In operation, a stop-rod 29 connected to the tool support 14 effects a restraining action on the tool support immediately before the end of a feed traverse by engagement between a stop 30 on the rod and a stop 50 on a member 49 fixed to the machine, displacement of the support occurs relative to the slide 5 and a plunger 32 engages in a recess 36 in the support side 14a thereby effecting retraction of the slide 5 by springs 8 to an extent equal to the depth of the recess 36. This retraction of the slide 5 effects movement of a disc member 39 by co-operation between stop portion 40 and stops 41, 42. The movement of the disc member 39 effects incremental displacement of a cam 35 through a oneway coupling, the movement of the cam controlling the position of the plunger 32 relative to the slide 5 which is consequently displaced incrementally towards the workpiece ready for the next traverse of the saddle. Immediately prior to the end of the return traverse of the carriage stops 47, 51 on a rod 46 and the fixed member 49, respectively, co-operate effecting pivoting of a bell-crank lever 44 on the member 4 which by engagement with pin 45 in-feeds the slide 5 with the chaser 25. Dial means is secured to the cam member 35 whereby rotation of the cam is indicated denoting the incremental feed of the slide and chaser. Increments of feed may also be effected manually by rotation of the dial.

Abstract: 1305003 Track apparatus TELEFONAKTIEBOLAGET L M ERICSSON 20 April 1971 [22 April 1970] 10299/71 Heading B7N [Also in Division G1] To detect a flat 18 (Fig. 1) on the rim of a wheel 13 of a rail vehicle, the two wheels 12, 13 on one axle 14 are used to close a test circuit which includes part of the rails 10, 11, which circuit is broken by the flat section 18 as the wheels rotate, for a period indicative of the length of the flat section. The connecting points 21, 22 to the rails 10, 11 are longitudinally offset by not more than the distance between consecutive axles. The voltage source 19 may be D.C., when the rail sections containing connecting points 21, 22 are insulated from the rest of the rails, or A.C., when the test circuit is made resonant at the test frequency to limit the effects of parallel paths through other wheel pairs. In one A.C. embodiment (Fig. 2A), the test circuit including wheels and axle b, c fed via transformer 33 is normally in series resonance at the supply frequency, whereby the voltage picked up at impedance 34 is sufficient to trigger unit 37 except when a wheel flat is present. The duration of the break in the output of unit 37 is compared with the time interval between  the operation of fixed switches SK1, SK2, to determine the length of the flat and to operate  an alarm 39 if it exceeds a preset value. In  an alternative arrangement the current in the test circuit is sensed by coils linked to the rails  10, 11 or to the wheel axle b, c, which automatically eliminate the effects of rail currents produced by other wheel pairs. In another embodiment (Fig. 5A), short auxiliary rails 40, 41 are mounted adjacent the main rails 10, 11 and each wheel of a pair 43, 44 completes a separate test circuit in which a flat section produces an open circuit.
