Abstract: An apparatus and a method are for separating a plastic-based insulation material from a concrete-based constructional element, to which the insulation material is attached. The apparatus has at least one fluid-jetting device which is in fluid communication with a pressure-generating device to produce a fluid jet with a pressure sufficient to release the insulation material from the constructional element. The apparatus is configured to allow relative motion between the fluid-jetting device and the constructional element.

Abstract: The present invention relates to a method for protecting the lower regions of and structure of a building from damage or degradation by termites. The method comprising for the steps of creating a region in the ground below the building having properties hostile to termites whereby to discourage them from approaching the vicinity of the building. In one embodiment means for creating a hostile region in the ground below the building are provided by a pump which creates a superatmospheric pressure field in this region. In another embodiment, treatment agents such as ozone may be delivered to the ground region in order to provide a hostile effect to the termites by affecting their pheromone chemistry and/or their reproductive or communicative behavior. A secondary function of the present invention relates to the creation of a forced ventilation of the habitable region within which the apparatus of the present invention resides.

Abstract: A fly repeller includes a housing; a motor contained within the housing; a rod having one end connected to the motor and rotatably driven by the motor, the rod extending from the one end through the housing to a distal end portion exterior to the housing; and plural arms fixed to and extending laterally from the distal end portion of the rod, wherein the arms are adjustable relative to the horizontal. The arm may be freely shaped by hand (manually) into a configuration which is held by the arms when rotated in use.

Abstract: Apparatus and methods for removing fleas and other debris from a domestic animal's skin while grooming the animal's hair is disclosed. A pair of spaced wedge-shaped frame members contain a motor and a speed reducer there between which together serve to rotate an endless belt around front and rear members of the frame of the device. The endless belt is constructed of the hook material of a hook and hook fastener material arranged in alternate rows of convexly curved, semi-flexible but resilient raised portions. A cleaning brush removes the fleas and debris from the endless belt and deposits the same in a removable receptacle. The endless belt arrangement results in undulating motion of the belt along the hair and skin of an animal in performing the flea-rid cleaning and grooming functions.

Abstract: A rotary insect trap is provided comprising a receptacle having an opening which is closed by an elongated rotor having a number of wings. Some of the wings are always in contact with the opening boundaries closing the interior of the trap receptacle against the surrounding. The rotor wings extend substantially across the whole length of the rotor and are shaped or made with a plurality of slots being in parallel with one another and extending rectangularly onto the rotor axis so that they separate gill-shaped radial portions of the wings from one another. A comb-shaped member comprising a plurality of teeth, pins or gills is arranged in the opening so that the teeth or the like engage each individual slot in the rotor for cleaning the surfaces of the wings when the rotor is rotated. The rotor can comprise a plurality of radial gills mounted spacingly onto a rotor shaft or can be moulded as an integral piece.
