Abstract: The blade of this saw, which can move about its longitudinal axis, can be oriented during the cutting by the handle or by a wheel. If it is directed by the wheel, the handle then directs the frame. If the handle directs the blade, the frame is free in its orientation. In order to prevent the blade from twisting, its tenons must be synchronised by a member which runs along the frame and which consists of a belt device, rods and gears or of teleflex cables. In order to give the inoperative elements play with respect to twisting, the movements of the control element are initially transmitted to the centre of the tenon-synchronisation device which re-transmits them symmetrically to the tenons. <IMAGE>

Abstract: In a mobile radio communication system, a mobile station (MR) constantly monitors a quality of a radio line between the mobile station and a first base station (BS1) with which the mobile station is presently communicating, detects a deterioration of the quality of the radio line between the mobile station and the first base station outside a tolerable range, successively detects field intensities of signals received from the base stations (BS2) neighboring the first base station using a free time slot which is unused by the mobile station for communication to determine a maximum field intensity, supplies to the first base station predetermined information related to a second base station (BS2) from which the signal with the maximum field intensity is received so as to make a handover request, and ends a communication with the first base station in response to a handover message. The first base station supplies a handover request message to a control station (CS) in response to the handover request from the mobile station, and the control station carries out a handover process in response to the handover request message. The handover process includes selecting a new communication channel with which the mobile station is to communicate with the second base station when the mobile station moves from a first radio zone (RZ1) to a second radio zone (RZ2), and notifying the handover message and the new communication channel to the mobile station and the first and second base stations, so that the mobile station ends the communication with the first base station in response to the handover message and starts a communication with the second base station using the new communication channel.

A new batch of ready mixed concrete can be prepared by weighing the amount of the sludge on the basis of the determined unhydration ratio. The ready mixed concrete thus prepared will have a desired hardening strength and drying shrinkage.
