Abstract: The present invention relates to a wall or floor chain sawing device (1), comprising a chain bar assembly (37) which in turn comprises a chain bar (2) having a longitudinal extension (17) and guiding a chain (3) at least partly around its perimeter. The chain bar assembly (37) further comprises a chain bar housing (6) that is attached to, and partially covers, the chain bar (2) and the chain (3). The chain sawing device (1) comprises a motor (9), a track interface (7) that is arranged to co-operate with a guiding track (8), and a power transmission arrangement (10) that is adapted to transfer a motion from said motor (9) to the chain (3). The sawing device (1) comprises a first pivotable support rod (12) and a second pivotable support rod (13), where each pivotable support rod (12, 13) has a corresponding first end (12a, 13a) and a second end (12b, 13b).

Abstract: Electric saw being powered by an external power supply through a multicore cable. The multicore cable includes electrical wires for supplying power to the motors of the electric saw and communication wires for data communication between the electric saw and the power supply. Two motors of the electric saw are three phase permanent magnet motors, with an outer rotor and an inner stator. Each of the two motors has three Hall Effect sensors located around the outer rotor.

Abstract: A spacer (1) for spacing a tool such as a drill motor from a tool stand such as a drill stand, the spacer (1) comprising a spacer body (2) and a locking member (3), the spacer body (2) having first (4) and second (5) opposing faces, the locking member (3) extending from a first end (6) thereof adjacent to the first face (4) to a second end (7) thereof adjacent to the second face (5), the locking member (3) being able to slide relative to the spacer body(2) along a direction from the first end (6) to the second end (7), the first end (6) and the second end (7) each being provided with at least one locking surface(10, 11), wherein the spacer (1) is arranged such that at application of a locking force each locking surface (10, 11) of one of the first and second ends (6, 7) transmits the locking force to each locking surface (10,11) of the other of the first and second ends (6, 7).

Abstract: A saw (1) being portable and/or wheeled, such as a wall saw, floor saw or masonry saw, comprising a rotatable circular saw blade (3), a drive motor (5) with an motor output shaft (9) for rotating the saw blade (3), and a transmission (20) for interconnecting the motor output shaft (9) to the rotatable saw blade (3) in order to change an unsuitable high speed and low torque combination of the motor output shaft (9) into a more useable lower speed and higher torque combination at the rotatable tool (3), wherein the transmission (20) comprises two adjustable friction saw protective clutches in parallel, which can be set at a desired predetermined value, so as to limit the maximum size of the forces that the teeth and gears of the transmission (20) are exposed to. No over dimensioning is necessary, and the transmission (20) will make out fine in rough environments. The transmission may be of single-speed or two-speed type.

Abstract: A method and a system for establishing communication among a plurality of network connected devices which are unaware of network and service addresses. The direct communication is facilitated by a network connected server device providing a common platform for a plurality of requesting devices to request a plurality of target devices by any means of initiation for a plurality of service attributes. The network connected server device has an intermediary function to make the system compatible with all means of initiation and wherein it is absent in service level communication of the devices.

Abstract: The present invention relates to an electric saw (1) being powered by an external power supply (200) through a multicore cable (6). The multicore cable (6) includes electrical wires (24, 25, 27) for supplying power to the motors (5, 12, 13) of the electric saw (1) and communication wires (26) for data communication between the electric saw (1) and the power supply (200). Two motors (12, 13) of the electric saw are three phase permanent magnet motors (12, 13), with an outer rotor (31) and an inner stator (30). Each of the two motors (12, 13) has three Hall Effect sensors (H1, H2, H3) located around the outer rotor (31).

Abstract: A mobile application running in a mobile device may be coordinated or synchronized with a non-mobile application running in a non-mobile device. The mobile and non-mobile applications may be, for example, calendar applications. To permit the use of a session-oriented (connection-oriented) protocol stack when the transmission medium between the mobile and non-mobile devices is connectionless, the mobile device sends an initial communication to the non-mobile device. In response to receipt of the initial communication, a session identifier is generated. A first connection-oriented protocol frame is then formed that includes an initial response and the session identifier. The first connection-oriented protocol frame is embedded in a first connectionless protocol frame, and the first connectionless protocol frame is sent to the mobile device. Although the mobile device initiates the session, the session is controlled by the non-mobile device.
