Abstract: Wire or cable pulling apparatus, comprising in combination a stand including an upright pedestal and a base supporting the pedestal; a frame mounted on the pedestal; a rotary axle supported by the frame, and a wire or cable pulling capstan carried by the axle, there also being a coupler associated with the axle for coupling an electrically powered driving tool in rotary driving relation with the axle and capstan; a boom having one end carried by the frame, and an idler carried proximate the opposite end of the boom, for entrainment by the cable or wire being pulled in response to capstan rotation when the boom is in operating position, extending at a first angle relative to the frame, the boom having a stored position in which the boom extends at a second angle relative to the frame.

Abstract: A freezing apparatus for liquid-filled pipelines (3, 5) uses a vaporizable refrigerant conducted in a circuit through a hose (13) with an internal capillary line (14). The apparatus has a contact body (1) with a contact surface (2) for the pipeline (3, 5) or for an adapter (4) and expansion chambers (6, 7) for the evaporation of the refrigerant. To improve the ease of handling and the thermal efficiency by making it possible for the temperature to be measured very close to the apparatus, the hose (13) is attached to the contact body (1) in the direction normal to a surface line of the contact surface (13). The contact body (1), furthermore, has a projection (16) at the side of the contact surface (2), this projection carrying a thermally insulated clamping spindle (17) for attaching the contact body (1) to the pipeline (3, 5). The spindle in turn contains a temperature sensor (20, 20a).
