Abstract: This invention relates to a method of reinforcing rubber with cellulose fibers which have been modified by graft copolymerization, and a fiber reinforced rubber product. Discontinuous cellulose fibers modified by graft copolymerisation are admixed into a conventional vulcanizing rubber mixture of a natural rubber or a synthetical rubber before vulcanization. Said cellulose fibers have been modified by graft copolymerization with at least a monomer of alkyl or alkenyl acrylate, alkyl or alkenyl methacrylate or a copolymer of two or more of said monomers. Compared to untreated cellulose fibers the modified cellulose fibers have a higher adhesion to the rubber matrix. The fiber reinforced rubber product has high strength and modulus.

Abstract: A fifthwheel coupling has a fifthwheel kingpin arranged on the semitrailer and a coupling plate which receives said kingpin in a slot with run-in slopes and is mounted on two bearing supports on both sides of the slot for compensating for jack-knifing movements between tractor and semitrailer and for facilitating the coupling process. The bearing support has sloping walls with which it is fixed on the tractor. To reduce the overall height and to improve the position of the centre of gravity and to increase the rigidity, the coupling plate has on its lower side a semispherical bearing head and the bearing support has a semispherical bearing shell which receives the coupling plate, and the walls of the bearing support are fitted on the bearing shell in the vicinity of its upper edges.

Abstract: PURPOSE:To reduce the irregularity of the cycle of an input signal by connecting a multiplier and a frequency divider between the input signal and a counter and making the output of the frequency devider a gate signal. CONSTITUTION:An input signal 11 is multiplied by (n) by a multiplier 1 and the output of the multiplier 1 is divided into 1/m in its frequency by a frequency divider 2. The output of the frequency divider 2 is supplied to a counter 3 as a gate signal 12 while he counter 3 opens and closes a gate following the gate signal 12 to count a reference clock 13 only during a gate open time. This count value becomes count data 14 as the output of the counter 3 to make it possible to reduce not only the irregularity of a gate time but also the cycle irregularity of the input signal.

Abstract: An AC current superimposed on a DC current is used as the power signal for the transducer and this signal is supplied to a current branch point in the power unit (5) for both the coil (1) and the current measuring sensor (6). The AC voltage differential over the coil is measured and used to generate a signal corresponding to the position of the transducer element (2) relative to the coil. DC voltage differential over the coil is also measured to generate a signal corresponding to the coil temperature.  The control method is used to measure linear movement and compensate for temperature variations in the transducer. Constant AC and DC generators are connected to a circuit containing the transducer coil and a current measuring sensor coupled in series with the coil. An Independent claim is also included for the control unit used to carry out this method.
