Abstract: 1336907 Treating I.C. engine exhaust: valve gear FORD MOTOR CO Ltd 29 April 1971 [2 June 1970] 12036/71 Heading FIB Internal combustion engine has means for injecting air under pressure into the combustion chamber and exhaust port at the end of the expansion stroke to oxidized carbon monoxide and CH compounds in the exhaust gases. The cylinder head 18 includes an exhaust valve 26 actuated by a push rod and rocker arm 28, and an additional valve 58 which is actuated in synchronism with the exhaust valve by a stud 66 in the rocker arm. A compressor supplies air to a gallery 46 in the head, which opens into a chamber 48 having a large diameter portion 50 and a smaller diameter portion 52 leading to a chamber 56 closed by the valve 58. In the large diameter portion 50 is a dual purpose check valve comprising a sleeve 82 having slots 104 and which can move into alignment with a groove 102 communicating with a passage 70 leading to the exhaust passage 24. A spring 86 biases the sleeve to the position shown in Fig. 2. Within the sleeve is a spring- loaded valve member 92 which seats on an apertured bridge 88. Operation The exhaust valve 26 and the additional valve 58 are opened as the piston approaches B.D. C. on the expansion stroke. Since the pressure in the combustion chamber will at this time be greater than the pressure of the air in the gallery 46, the sleeve 82 is forced upwards against the spring 86 and air flows through the slots 104 into the exhaust passage. As the pressure falls, the sleeve moves downwardly and shuts of the flow to the exhaust passage, the valve 92 moves off its seat and air flows into the combustion chamber past valve 58. In a modification the sleeve 82 is fixed in the large diameter portion 50 so that air passes continuously to the exhaust port. The valve 58 may have a deflector on the head and/or on the stem to direct the flow of air into the combustion chamber.

A fabric is compacted to produce a stretch fabric by a plurality of longitudinally curved in contact with at least one other roll 4. Prerolls 4 in parallel alignment, each roll 4 being ferably, the rolls 4 each comprise a curved shaft clamped at its ends, a series of metal roll sections rotatably mounted by bearings on the shaft and a rubber-like sheath forming the working surface. The rolls have an outside diameter of 1-6.5 inches and a bow sufficient to produce a campaction of 1-10% of the fabric as it passes over each roll. The fabric is fed from a roll 1 over a guide roll 2, through a steamer 3 and over the rolls 4, the fabric being presented at the convex side of each roll 4 and leaving at the concave side thereof. The roll 4 at the point of fabric ingress has the least amount of curvature while that at the point of fabric egress has the greatest amount. The fabric may be simultaneously set in the compacted configuration by a bank of infra-red members 5 and may be maintained in moistened condition by water vapour from a heated water bath 6. The fabric may be immersed in a water bath 7 by passing under a compactor roll 8 mid-way along the series of rolls 4. The compacted fabric is passed over a curved spreader roll 9 of larger diameter than the rolls 4 to remove wrinkles, under a squeeze roll 10, between squeeze rolls 10, 11 and is wound on a take-up roll 12 driven by a roll 13. In one Example, a wool fabric is passed into a reducing agent bath comprising sodium borohydride, between squeeze rolls and through a fourteen roll compactor apparatus of the type of Fig. 1. The fabric is then decatized, dried and semi-decatized. In another Example, a cotton fabric is compacted in a nineteen roll apparatus of the type of Fig. 1 and set in its compacted form by a dihydroxydimethylol ethylene urea cross-linking agent. Other Examples specify heat setting simultaneously with the compacting fabrics containing polyester continuous filaments and mixtures of polyester fibres with wool, cotton or rayon fibres.
