A property assessment system is provided to assess a property for various purposes. The system includes a property assessment apparatus configured to be inserted into any space of a property and retrieved therefrom once necessary information is collected from the space. The property assessment apparatus operates to monitor various conditions in the space, which is used to assess the property.

In a mobile system for pipe rehabilitation, a tractor moves a motorized electrical cutter inside a pipe. The cutter is used to remove a blockage from a branch conduit connected to the main pipe. A power management system powers the mobile system, including the cutter, from a direct current power source with an input current having a voltage less than 60V. The power management system powers the electrical cutter by discharging current from the supercapacitor module to the cutter. Power to other components is provided without discharge from the supercapacitor module and is not interrupted by supercapacitor discharge to the cutter. The power management system can include a housing for the supercapacitor module with a first connector at one end for connecting to an umbilical cord and a second connector an opposite end for connecting to the tractor.

The invention relates to a curing apparatus having at least one UV module (3), wherein the UV module (3) has at least one UV light source (6) for irradiating the inner wall of a pipe (1), wherein the UV module (3) that has been introduced into the pipe (1) is connected, by means of a cable (7), to a control device (9) that is situated outside of the pipe (1). It is an object of the invention to provide a curing apparatus in which the cable (7) for connecting the UV modules (3) to the control device (9) has a cross section that is reduced in comparison with the prior art. As a result, longer pipeline portions should be able to be renovated in one piece. Moreover, the electrical power losses in the cable (7) should be reduced. To this end, the invention suggests that at least one operating appliance (10) that is connected to the cable (7) and the UV light source (6) is arranged at each UV module (3), wherein the control device (9) actuates the operating appliance (10) by way of the cable (7) for the purposes of operating the UV light source (6).

Methods and systems are provided for treating the tail gas stream of a sulfur recovery plant. The methods including generating a tail gas stream from a sulfur recovery plant, treating the tail gas stream with a hydrogen sulfide absorption unit and a hydrogen selective membrane unit, generating a stream low in hydrogen sulfide and a stream rich in hydrogen. The hydrogen sulfide rich stream is recycled to the sulfur recovery unit. The hydrogen selective membrane unit includes a glassy polymer membrane selective for hydrogen over hydrogen sulfide and carbon dioxide.

A device for curing resin in a pipe liner using electromagnetic radiation includes a heat sink and LEDs for generating the radiation mounted on the heat sink. The device conducts heat away from the LEDs through the heat sink. The heat sink is positioned in the flow path of cooling fluid that draws heat away by convection. The heat sink can include elements at the ends of the LEDs that are exposed to the cooling fluid. The device can guide the cooling fluid along a flow path that includes a segment that extends over the LEDs. The device can limit fluid flow through a central cavity of the heat sink.
