    摘要: A shield excavator (4) is mounted in a seal body (9) which is rotatably mounted in a cylindrical skin plate (5) supported by a shield frame (8). A shaft (1) is excavated by propelling the shield frame (8) downwards and the seal body (9) is then pivoted in the skin plate (5) to orient the shield excavator (4) substantially horizontally and the shield excavator (4)is then propelled through an opening (26) in the side of the skin plate to excavate a tunnel (2).

    摘要: A parison head for use in a multi-layer blow moulding machine comprises a head body (1), a core (2) within the head body, a mandrel (4) at one end of the core which, together with the head body, defines an annular extrusion slit (6), a plurality of annular accumulator spaces (7-11) concentric with the core and a plurality of annular passages (12-16), each connecting one end of respective accumulator space with the extrusion slit. At least one of the passages (12-16) includes an annular valve (47) which normally closes the passage but is arranged to be opened when the pressure of the feed material in the associated passage exceeds a predetermined value.

    摘要: A flotation machine for de-inking waste paper stock comprises a horizontally extending flotation cell (5) defining a reservoir for a stock liquid which forms a free liquid surface in the cell. A froth receptacle (4) extends along the entire length of the cell and receives froth floating up to the liquid surface. At opposite ends of the cell are a stock inlet (1) and a stock outlet (2). Situated within the lower portion of the cell is a rotary air bubble generator (3) which extends between the two ends of the cell with its axis of rotation extending generally horizontally whereby stock liquid introduced through the inlet (1) flows along the length of the cell towards the outlet (2) in at least one spiral flow pattern (11) with a generally horizontal axis.
