The volume of a destructive agent is such as to enable the collecting vessel (50) to accommodate the destructive agent (61) in the absence of overflow. The destructive agent container (60,63) is placed above the collecting vessel (50) so that the destructive agent (61) will run or fall down into the collecting vessel when an alarm is triggered.
Abstract: A vacuum grooming tool is disclosed that includes a vacuum nozzle attachable to a vacuum source and has a hollow body with a mouth opening. A grooming device selected from a variety of standard animal grooming hand tools, such as a shedding blade, rake or de-matting tool, may span the mouth opening. The grooming device is positioned such that the airflow created by the vacuum source flows over at least one side of the grooming device. A vacuum cleaning tool for removing any animal hair from a grooming tool is also disclosed. A vacuum plenum of the cleaning tool is attachable to a vacuum source and has an opening for cleaning the grooming tool in one pass. The cleaning tool can be mounted on a stationary support may also include a pivot-action mechanism that connects the vacuum grooming tool or the cleaning tool to the vacuum source.

Abstract: An impact guard beam for vehicles comprises a beam (11) with a hat profile, i.e., with a crown (13-15) and side flanges (16-17), and the hat profile has its crown facing outwards. The beam has a cover (20) giving at least a central part of the beam a closed cross section. The cover has a profile allowing it to lengthen by straightening out when the hat beam's profile opens under impact loads, but stops the hat beam profile's opening when the cover is straightened out. The cover may carry a sensor (24) for an airbag, which is then placed inside the beam profile.
Abstract: A pulse drilling machine (1;1?) for the generating of shock wave pulses in a tool direction (R) has an impulse piston (4;4?) with a housing (2), and a device (8) for abruptly changing fluid pressure influencing the impulse piston to achieve a force resultant on the impulse piston in the tool direction to generate a shock wave pulse in a drill string (13; 13?) which is connected to the machine, a first fluid chamber (14;3?) inside the housing which in operation is arranged to exert a pressure in the tool direction on the impulse piston. The machine has a fluid flow channel (11; 18; 19), which includes a device for damping fluid flow flowing from the first fluid chamber through the fluid flow channel obtained when influencing the impulse piston (4; 4?) in a direction opposite to the tool direction (R) by rock reflexes in the drill string during drilling.

Abstract: A beam with a hat-shaped profile with a cross-section that varies along its length is successively formed from a plane sheet metal strip using a roll-forming machine with a number of forming stations. The forming stations (11, 12) have a pair of clamping rollers (21, 22 and 23, 24) for each side flange (16, 17) and support rollers (25, 26) for the central flange. The pairs of clamping rollers in the forming stations can be displaced both horizontally and vertically during a forming operation, and the support rollers (25, 26) can be displaced vertically and they can be displaced individually in a sideways direction. All four corners (27-30) of the hat-shaped beam are formed at the same time, whereby the corners are folded on the peripheral edges of the clamping rollers and support rollers. Not only the axes of the pairs of clamping rollers but also of the support rollers can be turned in order to adapt to the corners that are being formed.
Abstract: A method in core drilling, wherein a tubular drill bit (8) being arranged at the end of a tubular drill string (6) is driven under rotation against a material intended for drilling, and wherein for the purpose of core retrieving, a tool (17, 20) is brought inside the drill string to an operative position in the area of the drill bit. Acoustic vibrations (24, 25) from the drill string are sensed when the tool is brought to its operative position, sensed acoustic vibrations are analysed for detecting the occurrence of acoustic vibrations characteristic for when the tool has reached its operative position, and an output signal is emitted when the occurrence of vibrations characteristic of when the tool has reached its operative position has been detected. The invention also concerns a device and a drill rig.
