Title: Manufacture of shaped foamed articles t
IPC: B29C44/20
Filed: 1971-04-19
Abstract: 1345338 Moulding plastics foam BADISCHE ANILIN- & SODA FABRIK AG 19 April 1971 [21 Feb 1970] 22236/71 Heading B5A [Also in Division C3] A foamed product is obtained from a partially foamed particulate polystyrene homo. or copolymer by completing the expansion by heating with steam in a gas-permeable channel (for continuous production) or mould (for batch production). The channel, which is illustrated in the Figure, and the mould have at least two sides bounded by perforated walls. In the channel these are formed by movable belts 2. A gas, preferably air, is applied to the outside of the belts 2 during the falling expansion of the foam. The initial pressure of the gas is preferably about the same as the expansion pressure of the foam and is reduced to match the declining expansion pressure, always remaining within 50% of the expansion pressure. In the illustrated embodiment, the granules of polystyrene are introduced into the channel and pass chamber 7, wherd steam is applied and chamber 8 which is connected to a relief valve 10 and is sealed from succeeding chambers 9 and 5 to prevent gas escaping from them towards chamber 8. Chambers 9 are connected and supplied with gas at the required pressure. The gas escapes in the direction of chambers 5, thus setting up a pressure gradient as the foam exerts some counter pressure by reason of being in contact with the belts 2 when the last chamber 5 is passed. The belts 2 pass the chambers 5 without any sealing means. If the foam pressure exceeds the gas pressure the foam will force the belts against the chambers and build up the air pressure, and when the gas pressure exceeds the foam pressure, the belts are forced away from the chambers thus allowing excess gas to escape. Consequently the gas pressure adjusts itself to that required.

IPC: F02B9/04
Filed: 1921-08-25
Abstract: 189,225. MacDonald, J. D. Aug. 25, 1921. Two-stroke cycle engines; pumps; cylinders, ports of.-A double-acting air pump B supplies a reservoir G; the pump and power cylinders are connected at their centres by a port D, to allow a part of the combustion products to flow into the pump chamber at the end of the pump suction stroke and raise the initial pressure of the air in the pump. On the return or compression stroke of the power piston, the exhaust valve is closed to trap a part of the products; the air charge admitted from the reservoir is largely in excess of the amount required for combustion, so that the products contain a high proportion of air. The trapped products are compressed and fuel is injected into them and ignited by the heat of compression. At about oneseventh of the power stroke, air is admitted to the power cylinder from the reservoir, and a second injection of fuel is burnt with this air. The port D, Fig. 8, may be tangential in both the power and pump cylinders, and the passage between the two is cooled. The pump cylinder is water cooled, the cover being grooved to form water channels 5, Fig. 7, a plate 6 of highly conductive material covering these grooves. The cylinder has a channelled liner 4, water being circulated through these grooves, channels, and the passages for the exhaust cooler. The inlet ports to the pump are arranged tangentially. The air is admitted to the power cylinder through holes 7, Fig. 2, in a ring at the cylinder end, the holes being arranged to give the air a circular movement in the cylinder. The power cylinder shown is double acting, but one end of each cylinder may be a power chamber and the other a pump chamber. The cylinders may be coaxial or be disposed angularly.
