A method and a device for cutting gas concrete employing cutting wires (35), whereby, in order to decrease shocks and vibrations, and in order to cut blocks of gas concrete more rapidly and with a finer surface structure, said wires (35) are guided and driven separately from one another in such a way that they are guided in their lengthwise direction relative to a cutting frame (14) and that they ...

PURPOSE:To simplify the construction and the control method and reduce the cost of a vehicle control unit which receives various kinds of data concerning a vehicle by simultaneously carrying out at least both speed changing control and cruising control. CONSTITUTION:The detected signals from various sensors detecting respective operating modes of an engine 1, a stepless speed change gear 4 and a f...

PURPOSE:To improve the transmission efficiency and dissolve faulty return to low speed gear by regulating the oil pressure in a load thrust controlling oil chamber to the optimum oil pressure according to the torque generated at an engine and compensating the optimum oil pressure using the time variation ratio of car speed. CONSTITUTION:In a V-belt type stepless speed change gear a load thrust con...

PURPOSE:To improve the control precision of variation speed in speed change ratio by determining an error between the actual value of oil flow into the primary hydraulic cylinder of a continuously variable transmission and the target value and determining the duty ratio of a speed change rate controlling solenoid valve so as to make the error zero. CONSTITUTION:A control unit receives various dete...

A separator plate for the negative electrode of a lead-acid battery comprising a molded, synthetic plastic wall or planar member of generally rectangular configuration. A pair of like separator plates are vertically oriented in the battery casing to sandwich the negative electrode therebetween including juxtaposed retention mats common in such a negative electrode assembly. The sandwich provides a...

A transport cart for material carriers such as bobbins or drums having threads or other elongated material wound thereon, has a cart frame with wheels and a tilting frame journalled in said cart frame. The tilting frame carries two parallel skids for supporting a material carrier on its rollers. The tilting frame is tiltable between a first position in which the skids extend horizontally for loadi...

The tension in the rewound thread is modified in programmed manner as a function of the residual thread length still on a copy, the residual thread length being determined from the difference between the total thread length on the copy and the thread length already unwound from the cop. The total thread length on a cop is calculated from the weight of the thread and a calculation factor length per...
