Abstract: An inflatable stent for use in the repair and maintenance of pipes such as water or gas supply pipes, or for use as a medical device comprises an inflatable portion having an inner and outer membrane. When inflated, the inner and outer membranes are radially spaced apart to define an annular space there between. The inner membrane defines a passage between a first and second end and the outer membrane defines a first diameter (D1) of the stent. The inner and outer membranes are connected by a plurality of connecting members in the annular space. End caps are disposed on the first and second ends of the stent which connect the inner and outer membranes. The inflatable portion further comprises an inflatable pipe or lumen engaging portion that defines a second, larger diameter (D2) of the stent, when inflated.

Abstract: A device 1 for use with a continuous track 3 of a tracked vehicle to enhance the traction of the vehicle. The device 1 has an elongate body 5 having a ground contacting surface 6 and a releasable bracket 7 for releasably securing the elongate body 5 to the continuous track 3. The releasable bracket 7 has a bracket body 11, a first clamping member 13, a second clamping member 15 extending at an angle relative to the first clamping member, and a fastener 17. The bracket is arranged such that fastening the fastener 17 causes the second clamping member 15 to draw the first clamping member 13 towards the elongate body 5 to releasably secure the elongate body 5 to the continuous track 3. The device has one or more ground engaging features 39. A kit of parts is also described.

Abstract: An insulated core stud for use in the core structure of at least one of a stator and a rotor of a dynamoelectric machine is adapted to pass through holes contained in laminations of the core structure. The insulated core stud has a central portion and a first layer of heat shrinkable tubular insulation shrunk fit onto and covering at least the central portion of the core stud that passes through the laminations. One or more additional layers of heat shrinkable tubular insulation are shrunk fit onto at least a portion of the first layer of insulation that passes through the laminations. These second layers provide mechanically protection to the underlying layers of insulation against breaks occurring in the electrical insulation when the laminations and core studs are assembled into the core structure.

Abstract: A conduit housing for enclosing the juncture between a roof and an elongated conduit such as flexible cable or a pipe extending upwardly through the roof is disclosed. The housing may be installed while the conduit remains in situ and without disconnecting the conduit from an external utility to which it is connected. The housing includes first and second base sections, a hood, and a conduit opening extending through a side wall of the housing. The base sections are slidably engageable with each other around the conduit on the roof to form a base assembly. The base assembly has an open top and extends peripherally around an interior region containing a lower portion of the conduit. The hood is engageable with the base assembly to cover at least the open top of the base assembly. The conduit opening is sized to provide a passage for the conduit from within the interior region to an external region outside the housing, and it may extend through a side wall of the base assembly or a side wall of the hood.

Abstract: Apparatus and a method for extending the length of a vent pipe for a predetermined distance above the elevation of a building roof includes an elongated extension pipe connectable with the vent pipe, a flashing attachable to the roof while fitted as a sleeve over the extension pipe, and a vent cap fittable over the flashing and the extension pipe. The vent cap includes an opening for venting to external atmosphere gases received by the extension pipe from the vent pipe. The extension pipe and the vent cap are sized so as to maintain a venting pressure in the extension pipe not greater than the venting pressure in the extension pipe.

Abstract: Sorting apparatus has a delivery system for creating a stream of product pieces to be sorted in free flight at a sorting station where selected pieces are rejected from the stream. The system comprise a delivery conveyor inclined to the horizontal for receiving product and directing it towards the sorting station. The length of the delivery conveyor, its inclination and speed are selected to effectively create a low friction chute and establish a uniform, stable and constant velocity product stream for delivery to the sorting station.

Abstract: A method for wet cleaning of the nozzle rings of exhaust-gas turbocharger turbines is based on thermal shock of the contaminants, and includes the steps of injecting water in repeated, relatively small amounts, into the exhaust duct immediately upstream of the nozzle ring. A delay between injections allows the nozzle ring to reheat to operating temperature so that each water injection causes a thermal shock. An apparatus to perform the method includes water injection nozzles installed in the exhaust gas casing and a control system. The method and apparatus provide improved cleaning using less water than in known methods.

Abstract: A sorting apparatus for sorting material into desired and undesired pieces or portions includes a moving reflective surface such as a rotating cylindrical drum which is interposed between an illuminated background and a viewing system so that the background is indirectly viewed via the reflective surface. Any liquid or other debris from the product spills onto the reflective surface, rather than the background and is then moved away to be cleaned off. Thus, the viewed optical characteristics of the background remain constant and periodic cleaning of the background is not required.
