Abstract: The present invention is directed to a scroll type compressor having an injection mechanism in which a part of the refrigerant flowing from the condenser is combined with the refrigerant in the intermediately located fluid pockets of the scroll elements in order to increase the amount of heat radiation from the refrigerant in the condenser without increasing the capacity of the compressor and in order to prevent operation of the compressor at a thermally severe condition. The injection mechanism includes a horseshoe-shaped groove formed between a circular end plate of a fixed scroll and an end portion of a casing adjacent to the circular end plate, a pair of axial conduits formed through the end plate of the fixed scroll and an axial hole formed through the end portion of the casing. The refrigerant is conducted to the intermediately located fluid pockets of the scroll elements via the axial hole, the groove and the axial conduits which are connected in series for fluid communication. In accordance with the present invention, the injection mechanism is easily assembled, and the thermal influence of the high temperature discharged refrigerant gas in the discharge chamber of the injection mechanism is negligible so that the operation of the compressor at a thermally severe condition is effectively prevented.

Abstract: A method for insolubilizing detrimental heavy metals contained in a fly ash collected from an exhaust gas discharged from an incinerator. For the purpose of making insoluble the heavy metals, a chelating agent comprising a high-molecular compound is added, together with water, to the fly ash, or a chelating agent, a high-molecular compound and water are added to the fly ash, and these substances are kneaded to form a kneaded mass. Reactions are caused in the kneaded mass between these heavy metals and the chelating agent to convert the heavy metals into water-insoluble chelate compounds, and the chelate compounds are coarsened.

Abstract: A scroll type fluid displacement apparatus including a housing and a pair of scrolls having interfitting spiral wraps which undergo relative orbital motion to make moving line contacts and define sealed off moving fluid pockets of changing volume. The center portion of at least one of the wraps is higher than the remaining portion thereof. The center portion extends substantially from the inner end of the spiral wrap outwardly at least to the location of the line contact between the curved surfaces of the wraps when the innermost pair of fluid pockets are merged into a single fluid pocket to form the high pressure space near the center of the scrolls. This construction prevents abnormal wear of the spiral wrap and the opposite end plate which might otherwise occur during axial slant of the orbiting scroll, or which might be caused by non-parallelism of the scroll end plates, without compromising the important sealing of the central high pressure space.
