A ball 10 of slightly larger diameter than the bore of the spout 5 may be engaged in the neck of the spout. The flexible tube 11 is fitted with a flow control clip 13, and terminates in a rectal tip 12. The bag may be filled with, say, a liquid X-ray contrast medium via the port 7, which is then sealed with cap 8, the tip 12 is inserted through the anus of a patient, and, after displacing the ball 10 into the bag by manipulation of the spout, and release of the clamp 13 the liquid may be forced into the gut by squeezing the bag. After discharge of the liquid the gut may be evacuated by releasing the sides of the bag, or, the tube 11 may be removed from the spout 5 and connected to other apparatus.

Class 110(3) [Also in Group XXXIV] In a gas turbine engine provided with means for injecting a liquid into the cooling air flow, the injection is initiated when the temperature of the cooling air rises above the vaporizing temperature of the liquid. In the jet engine of Fig. 2 air from an intermediate stage of the compressor 10 is supplied to the interior of the hollow shaft 19 via ports in the latter and in the compressor rotor. This air flows through ports 30 in the shaft to a chamber 40 whence it is directed over the bearing housing 26 and passes to the atmosphere through the hollow inlet varies 33 of turbine 13. Air from the combustion chamber jacket 36 is fed through conduits 34 to a chamber 39 and after flowing over the bearing housing 27 flows over one side of the turbine disc 23 and enters the working fluid stream. Temperature-sensitive devices 50 are adapted to operate the control switches 49 of motors 46 driving water pumps 43 adapted to feed atomizing nozzles 41. The devices 50 are also adapted to close the valves 54 in the by-pass connections 59 to increase the water supply to the nozzles. In Fig. 3 the lubrication system for the bearings comprises a storage tank 63, supply and scavenge pumps 65, 73 and a coil 67 located in a cooling air duct. Operation of the motor 46 driving the water pump 58 is controlled by the heat-sensitive device 50. The pump feeds the atomizing nozzle 76.

Abstract: 980,036. Spinnerets. MONSANTO CO. June 24, 1963 [June 25, 1962], No. 24999/63. Heading B6B. A laminated spinneret 10 useful in making conjugate filaments comprises a double-feed end block 12, a single feed end block 14 and a stack of plates comprising alternate orifice plates 36 (Fig. 3) and spacer plates 48 (Fig. 4). Orifice plates 36 each have a distribution aperture 45 and a Y-shaped void 38 terminating in a slot 40. Spacer plates 48 each have three distribution apertures 46. In stacking, alternate orifice plates are reversed so as to offset the slots 40 which form extrusion orifices. A spinning composition supplied to the single feed end block 14 is conveyed to the middle distribution channel 51 formed of the central apertures 46 of the spacer plates and the branches 44 of the Y- shaped voids of the orifice plates. A second spinning composition supplied to the double-feed end block 12 which may be the same as the first spinning composition, or different if conjugate filaments are desired, is conveyed by the branched portions 28 and 30 of the distribution passage 26 to the two outermost distribution channels 50 and 52. Each of these channels is formed of the branches 42 of the Y-shaped voids of alternate orifice plates, and the outermost channels 46 of the spacer plates 48. Hence the two compositions merge and exit from the orifices 40 as conjugate filaments. Using sufficiently thick orifice plates, the spacer plates may be omitted. A given orifice slot 40 may be supplied by more than two feeder passages, a third spinning composition thus being supplied to slot 40. In a modification (Figs. 6 to 8), spacer plates 48 (Fig. 8) are interposed between orifice plates 36, alternate orifice plates being reversed (Figs. 6 and 7) so as to offset the slots 40, and on either, or both, sides of each orifice plate a continuous wave-like recess is formed, embracing each pair of feeder passages 42, 44, the crest of the recess registering with the distribution apertures 46 in spacer plate 48 feeding passages 42 and 44 when the orifice and spacer plates are stacked in alignment, and the bottom of the recess communicating with the edge of the orifice plate by way of slot 40 which defines a spinning orifice.
