Abstract: Apparatus for the delivery of material to a pipe is disclosed. The apparatus comprises an inlet configured, in use, to receive a fluid flow, an outlet configured, in use, to deliver the fluid flow to a pipe and an instrument receiving location for, in use, receiving at least part of an instrument. The apparatus further comprises an access arrangement for, in use, selectively providing or preventing access to the instrument receiving location, wherein the inlet and/or the instrument receiving location is configured, in use, to be connected to at least one elongate flexible conduit.

Abstract: Apparatus (100) for the delivery of material to a pipe is disclosed. The apparatus comprises an inlet (104) configured, in use, to receive a fluid flow, an outlet (112) configured, in use, to deliver the fluid flow to a pipe and an instrument receiving location (124) for, in use, receiving at least part of an instrument (128). The apparatus further comprises an access arrangement (110, 122, 133) for, in use, selectively providing or preventing access to the instrument receiving location (124), wherein the inlet and/or the instrument receiving location is configured, in use, to be connected to at least one elongate flexible conduit.

Abstract: An apparatus is disclosed for locating an instrument within a pipe. The apparatus may include body portion defining a cavity therein, a pipe engagement region for slideable engagement with a pipe, and an instrument retention portion for receiving at least a portion of an instrument therein and retaining the instrument in position relative to the body. A method is also disclosed including the use of the apparatus to locate an instrument within a pipe.

Abstract: Apparatus for dispensing abrasive particulate material into a stream of gas, the apparatus comprising: a. a pressurized hopper for receiving particulate abrasive material; and b. a pressurized conveyor coupled to the hopper comprising a housing having an inlet for receiving particulate material from the hopper, an outlet for delivery of particulate material from the housing, and a screw located within the housing for transporting particulate material from the inlet to the outlet. Also provided is a method of dispensing particulate abrasive using said apparatus and a pipe cleaning system including said apparatus.
