    • A liquified gas cryostat having an inner wall (3) to contain the liquified gas (4) and an other wall (2) spaced therefrom is provided, in the space between the two walls, with multilayered insulation (5), formed by coating a woven fabric with a thin layer of gold or aluminium to create small, self-defined areas of metallization, and the space is evacuated. Also in the space is located at least one radiation shield (6) of material which exbibits high thermal conductivity and negligible electrical conductivity. The shield (6) extends beneath and is continuous around the inner wall (3) over the volume intended to be occupied by the liquified gas and may be vapour-cooled or cryo-cooled. Where more than one shield is used, both or all of them may be vapour-cooled or cryo-cooled. Alternatively, one or more of the shields may be vapour-cooled and the remainder cryo-cooled.

    • A moling apparatus (2) comprises a housing (4) having a head (8) for penetrating ground, an anvil (16) disposed in the housing connected to the head, a hammer (18) disposed in the housing and spaced therefrom by resilient restraint means (20). A vibrator unit (42) is spaced from the hammer and arranged to transfer vibration to the housing and the hammer. In a first mode of the apparatus, vibration transmitted to the housing causes fluidization of the surrounding ground to allow progressive penetration of the apparatus. In a second mode, the braking effect of the ground on the head causes the hammer to move against the resilient means and impact the anvil thereby driving the head through the ground, said apparatus being operable at or between said modes.
    • 磨牙装置(2)包括具有用于穿透地面的头部(8)的壳体(4),设置在连接到头部的壳体中的砧座(16),设置在壳体中的锤子(18) 约束装置(20)。 振动器单元(42)与锤子间隔开并布置成将振动传递到壳体和锤子。 在设备的第一模式中,传递到壳体的振动导致周围地面的流化,以允许装置的渐进穿透。 在第二模式中,地面在头部上的制动效果使锤子抵靠弹性装置移动并冲击砧座,从而将头部驱动通过地面,所述装置可在所述模式之间或之间操作。
