Title: Deriving differential quotient for tool stress measuring - using angular velocity of rotary workpiece or tool as actual value for comparison with rated value
Inventor: NAHR HORST DR
IPC: B23Q15/12
Filed: 1980-05-30
Abstract: The measuring is carried out either for the tool or the workpiece. When the machine tool is driven by an electric motor etc. its speed is reduced with increased load. The angular velocity of the rotary workpiece, or a rotary tool is compared in its actual value with a rated value. Thus the change of the angular velocity in time is measured as the differential quotient, which serves as a control magnitude. In the device for this measuring process a pulse generator rotate at the speed of the rotary part (workpiece or tool), which comprises pulse generator parts, uniformly distributed over the periphery of its rotation. The centre point of this periphery lies in the rotary axis of the respective part. A stationary pulse receiver is arranged in the effective range of the pulse generator parts, while a comparator circuit for the actual angular velocity of these parts compares the rated value.

Title: Method and apparatus for recovering the tobacco from reject cigarettes
Inventor: SCHAACK TONY
IPC: B07B9/00
Filed: 1981-06-26
Abstract: In order to recover the tobacco from reject cigarettes, primarily from filter-tipped reject cigarettes, the cigarette paper wrapper is torn open and removed, together with the filter. To this end, the reject cigarettes as a whole are subjected to a mechanical loosening effect and, in the loosened state, are subsequently directly subjected to a sieving process, in which the tobacco and the paper together with the filters are removed separately. To this end, use is made of a loosening machine (2) with rotor and stator discs having loosening segments, (17, 18), the reject cigarettes which have thus been loosened then being directly further treated by means of a vibratory conveyor trough (3) with screen insert (4). Complete separation of the constituents is thereby achieved and the recovered tobacco can be reused. <IMAGE>

Title: Hydropneumatic accumulator
Inventor: BUDECKER LUDWIG
IPC: F15B1/14
Filed: 1982-03-04
Abstract: The invention starts from a hydropneumatic accumulator with a housing whose inner space is subdivided by two dividing bodies into three chambers, in which accumulator the inner chamber lying between the dividing bodies has a constant volume and is filled with fluid and in which the two outer chambers can be varied in their volume, in which arrangement one outer chamber can be filled with gas and the other outer chamber can be loaded with hydraulic oil. In the known accumulator, one of the dividing bodies is designed as metal folding bellows which are intended to prevent an exchange of gas. In contrast, the present invention proposes that, to avoid an exchange of gas, one of the dividing bodies (10, 15) be designed as a piston (15) guided in a sealed manner in a housing bore. This results in an accumulator which is simple to produce and is safe in operation. <IMAGE>
