Title: Evacuation of liquid from sumps
Inventor: BYATT HERBERT ALFRED
IPC: F01M11/04
Filed: 1965-03-04
Abstract: 1,094,021. Cleaning engine sumps. H.M. POSTMASTER GENERAL. March 1, 1966 [March 4, 1965], No. 9267/65. Heading A4T. Apparatus for evacuating liquid, especially oil, from a sump 1 comprises a reservoir 10 with means 20-24 for making a fluid tight connection with the bottom 3 of the sump and means for creating a subatmospheric pressure in the reservoir 10 to draw the contents of the sump into the reservoir. As shown, the reservoir 10 is connected to the constricted portion of a venturi 25 through which air is passed from a compresser 28 and control valve 27 to atmosphere thereby to create a pressure reduction in the reservoir. A bottom outlet 12 in the reservoir 10 is normally closed by a spring biased valve 14, 15 and by the reduced pressure in the reservoir 10. When the oil transfer to the reservoir 10 is completed, the pressure returns to atmosphere and the valve 14 opens under the weight of oil in the reservoir 10 so that the oil is transferred to a secondary reservoir 11. In another embodiment (Fig. 2), a flow control valve (43) disposed in the outlet from the venturi 25 may be closed after transfer of oil "from .the sump to the primary reservoir (30) so that air from the compresser 28 is directed into the reservoir (30) to force the oil through a spring loaded primary reservoir outlet valve (34, 35) and into a remote secondary reservoir (31). The oil inlet to the primary reservoir (30) is fitted with a non-return valve (40) which closes when the reservoir (39) is pressurized.

Title: Improved electric disengaging devices for warping machines for yarns or threads
IPC: D02H13/00
Filed: 1929-03-22
Abstract: 308,799. Hochheimer, E. March 28, 1928, [Convention date]. Yarns, warping &c. - The yarns from the bobbins 2 on the spool frame 1 pass through the eyes of guard needles 6 suspended by means of metal sleeves 6a from insulated contact wires 5. When a yarn breaks, a guard needle falls into contact with a contact wire 4 thereby completing an electric circuit through an interrupter 10 and an electromagnet 11, whereby the driving mechanism of the machine is disengaged and simultaneously a brake is caused to be applied to the warping drum 3 to stop this quickly and so prevent the broken varn being wound thereon. The core of the electromagnet 11 may be connected to a chain wrapped around a shaft 29, which is rotated when the electromagnet is excited, a tappet 30 on the shaft engaging a spring-controlled locking-rod 26 connected to a pedal 24 mounted on levers on a shaft 22. The rod 26 is thereby moved away from a stop 28, so that it can rock the shaft 22. By means of lever mechanism 21, 20, a weight lever 17 is operated, having a bevelled hub 18 bearing against the machine frame and against the bevelled hub of a loosely-mounted brake cone 13, which is forced against the action of a spring into contact with a brake drum 12 fast on the shaft of the warping drum. By means of lever mechanism 43, 42, 41 the shaft 22 also turns a bevelled collar 40, which is loose on the driving shaft 34, and moves it away from the bevelled hub of a clutch drum 40, thus allowing a spring 39 to move this drum away from driven engagement with a coupling cone 37 fast on the driving shaft, so that the machine is stopped. A belt 45 passing round the clutch drum drives a pulley, which drives the warping drum through spur gearing. The electromagnet solenoid operates the current interrupter 10 by means of a switch 33. Separate electromagnets may be used for operating the brake mechanism and the disengaging devices of the driving mechanism respectively.
