Abstract: 1. A trap for rodents, including in particular rats, said trap comprising: a housing; and a trapping chamber in which a passage extends from the side(s) of the housing. The trap further comprises two electric poles, of which the one electric pole is disposed outside the trapping chamber and a reservoir. The trap is moreover configured with a transport mechanism for the transport of the trapping chamber with rodent between a lower position in which the rodent is able to run into the trapping chamber and an upper position in which the trapping chamber is able to discharge a destroyed rodent into the reservoir. The trapping chamber and the electric poles comprise means to the effect that the electric poles can be caused to be situated close to each other within the trapping chamber.

Abstract: A rat trap (1) comprising a power supply (80) and means (3) for killing a rat and a first sensor adapted to detect the presence of a rat in the space within the reach of the killing means and where control means are arranged capable of receiving a signal from the first sensor, and being adapted for activating the killing means (3) to kill the rat when the presence of the rat is detected by the sensor according to the invention the trap further comprise a second sensor (85) for detecting light, and the control means is capable of receiving a signal from the second sensor (85) and being adapted for deactivating the killing means (3) or the first sensor for a period of time after the detection of light by the second sensor. Hereby it is possible to prevent accidents due to e.g. erroneous activation of the trap in case of ordinary localised work illumination, including e.g. also in daylight at ground level or in artificial work illumination at the bottom of a shaft.

Abstract: A method and a console for the installation of powered equipment (1) in front of a sewer pipe opening (41) in a sewer shaft (50), the method comprising the steps of, selecting resilient tubular member (40) comprising a console adapted for mounting the powered equipment, the resilient tubular member having, in its unstressed state, an outer radius which slightly exceeds the inner radius of the sewer pipe opening, mounting. the powered equipment on the console positioning the resilient tubular member in front of the sewer pipe opening and compressing the resilient tubular member to obtain an outer radius being smaller than the inner radius of the sewer pipe opening, Inserting into the sewer pipe at least a part of the resilient tubular member, so that the console with the powered equipment extends inside the sewer shaft, releasing the compression of the resilient tubular member (40), so that it expands to engage with the inside of the sewer pipe opening (41).

Abstract: A rat trap which comprises: a plate with a first side and a second side and with a number of through-going openings from the first to the second side. The trap has a number of spikes secured to an anchoring plate which is arranged on the top face of said plate and wherein each spike is adapted to the individual openings in the plate to the effect that a spike is able to slide through the plate from the first side of the plate to the second side of the plate. Moreover, the plate has an infrared sensor which is adapted to detect the presence of a rat within the reach of the spikes. The trap is able to eject one or more of these spikes through the openings when the presence of a rat is detected by the infrared sensor. The rat trap further comprises a withdrawal mechanism which, following a given period of time, withdraws the spikes through the openings in the plate whereby the rat spiked by one or more spikes is released.
