Abstract: Vacuum spinning of yarn produces yarns having good properties, and which may have a wide variety of different effects and constructions. A core filament yarn may be fed into operative association with a nipped sliver or roving, and then fed to a perforated rotating hollow shaft operatively connected to the vacuum. The core filament yarn may be a full stretched textured yarn, which is placed under tension and while under tension is dragged over a sharp edge of nonconductive material, and after the tension is relieved develops crimp. This causes individual fibers to be repelled, and provides for intermixing of the nipped sliver or roving fibers and the core filament yarn fibers. Alternatively, the filament yarn may be acted upon by draft rollers before the entrance to, and after the exit from, the hollow rotating shaft, to apply a force that breaks up to about 20% of the fibers. The yarns produced utilizing the broken fibers has a spun-like appearance.

The sleeve is configured so as to duct spent impingement air towards the combustor, where it can be subsequently used for mixing with, and combustion of, the fuel, or for cooling of the combustor. The distance between the impingement sleeve and the transition duct surface is varied to control the velocity of air crossflow from spent impingement air in order to minimize the pressure loss due to crossflow. The cross-sectional areas of the apertures are varied to project impingement jets over the various distances and crossflow velocities. Generally, larger aperture areas are used with larger distances.

Abstract: An installation for the control of the fuel supply to the afterburner of a bypass jet propulsion unit which permits an individual modulation of the fuel flows to the different burner systems, namely, the ignition burner, the main burner in the inner flow and the burner in the bypass flow. For this purpose, separate fuel pumps are coordinated to the inner flow and the bypass flow. The two fuel systems of the inner flow are thereby so linked from a shifting and regulating point of view that they can be individually modulated without mutual reaction. The fuel system of the bypass flow is independent of the fuel system of the inner flow so that the modulation thereof also has no reaction on the fuel system of the inner flow.

Abstract: A particulate oxidizer system for a diesel engine comprises a diesel particulate oxidizer (DPO) in the exhaust line to collect and burn particulates in the exhaust. The DPO comprises ceramic foam with a catalyst. When the quantity of particulates in the DPO reaches a predetermined value, high temperature gas containing oxygen is fed to the DPO to burn off (regenerate) the collected particulates. This is achieved by retard control of the injection timing under control of an engine control unit (ECU). A regeneration timing detection means detects the regeneration timing in the DPO. When the quantity of particulates in the DPO falls below a predetermined value, the ECU provides a signal to increase the idling revolution of the engine.
