Abstract: The traversing bridge serves to load or unload a lorry driven up close to the ramp (1). During operation, the bridge plate (3) is first raised and the lengthening piece (5) extended. It is then lowered until the lengthening piece rests on the floor of the lorry. During retraction, the bridge is retracted first and then the lengthening piece (5). So that the withdrawal takes place only after the lifting, a flow regulator (13) is fitted in the pressure line (10) to the cylinder (8). The limit switch (72) stops the retraction movement, the limit switch (73) indicates that the collapsible support (61-63) is extended and the limit switch (71) indicates that the bridge is in the inoperative position and the pressure-medium pump can be switched off and the pressure can be allowed to escape. <IMAGE>

Abstract: In order to calibrate an appliance for measuring force or moment, the measuring element (l) carries a strain gage bridge (R1, R2, R3, R4) for delivering a signal which is mainly sensitive to the force or to the moment to be measured and is provided at the time of manufacture with two other strain-gage bridges (R5, R6, R7, R8); (R9, R10, R11, R12) for delivering signals which are mainly sensitive to two parasitic stresses other than the force or the moment to be measured. In a first stage, the method consists in measuring the signals delivered by the three strain-gage bridges in the absence of any load applied on the measuring element, then under a number of known reference loads chosen from among those to which each strain-gage bridge is the most sensitive. In a second stage, the reference measurements are used as a basis for calculating the parameters of sensitivity according to which each of the signals delivered by the measuring bridges is a function of the applied loads. In a third stage, these parameters of sensitivity are used as a basis for calculating the correction to be made in the force or the moment measured by the first strain-gage bridge (R1, R2, R3, R4).

Abstract: Disclosed herein is a gas sensor comprising a membrane for gas sensing which comprises a selective gas permeable membrane and a reaction layer attached thereto; and a counter electrode separated from the reaction layer of the membrane across an electrolyte; the reaction layer having the function of an electrode and comprising fine hydrophilic portions and fine hydrophobic portions. 
     The specific gas in mixed gases having permeated the selective gas permeable membrane is immediately dissolved in the electrolyte having penetrated into the reaction layer and is ionized and the ion in the electrolyte moves to the counter electrode closely positioned to the reaction layer so that the specific gas concentration can be detected by means of the voltage difference or the like. 
     Since, therefore, in the sensor of the present invention, the specific gas easily reaches the counter electrode, the response time can be greatly decreased and the scale of the apparatus can be easily made smaller because extra equipment and space are not required.
