Patent
Hilti Ag | Date: 2017-02-08

The invention relates to a screw, in particular a concrete screw, having a shaft (110, 410) that has a front end for introduction into a borehole in a substrate and a rear end, and at least one thread coil (111, 411) that is provided on the shaft. According to the invention, the screw has an extrusion plunger (130, 230, 330, 430) which is provided in front of the front end of the shaft, a compound reservoir (160, 460) being provided between the extrusion plunger and the shaft.

The invention relates to a method and a system for controlling injection processes in liquid fuel-operated setting devices (1) which comprise a fuel tank (8) from which fuel is supplied to a combustion chamber (12) by means of a time-controlled metering device (10). In order to further improve the controlling of injection processes in liquid fuel-operated setting devices (1), a metering time of the time-controlled metering device (10) is adapted to the age of the fuel tank (8).

The invention relates to a hand-held or semi-stationary setting device (1) for driving fastening elements into a substrate (3) with the aid of a working piston (8), said device comprising a housing with an attachment device (14) at one discharge end (5). In order to simplify the operation of a hand-held or semi-stationary setting device, the working piston (8) is coupled to the attachment device (14) such that when driving a fastening element into the substrate (3), energy of the working piston (8) is absorbed and is transferred to the attachment device (14), in order to press the attachment device (14) against the substrate (3).

The invention relates to a composition which contains a binder based on thiol-ene. Said claimed composition makes it possible to apply, in a simple and rapid manner, coatings that have the layer thickness required for the respective fire resistance grading, the layer thickness being reduced to a minimum while achieving a good fireproofing effect. Said claimed composition is particularly suitable for fire protection, especially as a coating for cables and cable routes for increasing the fire resistance grading.


The invention relates to an anchor device for fixing an insulating board to a building structure. Such a device is provided with a screw (20) having a self-tapping thread (22) for tapping concrete and/or masonry, and a retaining washer (10), connected to the screw (20), for securing the insulating board to the screw (20). According to the invention, the screw (20) is made of stainless steel.


Patent
Hilti Ag | Date: 2017-01-11

The invention relates to a method for controlling a machine tool, in particular a core drilling machine, comprising a motor for driving the machine tool, a control device, a power display, a gear mechanism having at least one first gear and one second gear, a first sensor for detecting the rotational speed of at least one component of the gear mechanism, and a second sensor for detecting the rotational speed of the motor. The method comprises the method steps: detecting a first rotational speed of the at least one component of the gear mechanism when the gear mechanism is engaged in a gear; detecting a first rotational speed of the motor when the gear mechanism is engaged in a gear; detecting the engagement of the gear based on a first predetermined ratio of the first rotational speed of the at least one component of the gear mechanism and the first rotational speed of the motor according to a lookup table; and setting the threshold value of the power display based on the lookup table corresponding to the engaged gear. The invention further relates to a machine tool for applying the method.

The hand-held power tool (1) according to the invention has a tool holder (2) for holding a tool (4) on a work axis (11) and a percussion mechanism (6) which comprises a striker (14) which is moved periodically back and forth on the work axis (11). The percussion mechanism (6) is fastened in a machine housing (20). A handle (9) is fastened to the machine housing (20) by means of a damper (21). The damper (21) has a machine-side surface (25) connected to the machine housing (20) and a handle-side surface (24) connected to the handle (9). A block (27) of a porous elastomer is arranged so as to bear on the machine-side surface (25) and on the handle-side surface (24). An air-filled cavity (30) is provided within the block (27) between the machine-side surface (25) and the handle-side surface (24).

The invention relates to a driving-in device, comprising a handheld housing (1), a piston element received in a piston guide (2) for transmitting energy from a propelling charge (3) to a securing element (4) to be driven, and a front part (6) which is removably connected to the piston guide (2). The front part (6) and the piston guide (2) can be moved relative to each other parallel to a central axis (A) of the piston element, and the front part (6) is released from the piston guide (2) by rotating the front part (6) relative to the piston guide (2) by a release angle, wherein a torque barrier of a securing element (7) is overcome upon rotating by the release angle.

The scanning detector (1) is designed to detect and to identify first structures (2) only made of iron-based objects (7) and second structures (6) comprising iron-based objects (7) and non-magnetic and highly conductive metallic objects (8). The structures are below a surface, for instance embedded in masonry. A movement sensor (13) determines a movement of the scanning detector (1) along a measuring-direction (9). A field-sensor (13) comprises a pair of primary pickup-coils (24, 25) along the measuring-direction (9) and an excitation-coil arrangement (22, 23) arranged between the primary pickup-coils (24, 25). A current source (31) injects an alternating excitation-current (33) in the excitation-coil arrangement (22, 23). Thus, the excitation-coils are emitting a corresponding alternating magnetic field. A phase-analyser (38) determines a phase (phi) between the alternating excitation-current (33) and a difference (36) of induced voltage-signal (34 in the primary pickup-coils (24, 25). An interpretation unit (17) determines a slope of the phase (phi). The interpretation unit (17) identifies a structure by discriminating among the first structures (2) and the second structures (6) based on whether the slope is increasing or decreasing. A display (18) or a transceiver (20) is used to inform the user about the identified structure.
