Patent DE-3822309-A1 (DE)
Inventor: THOLANDER LARS HELGE GOTTFRID
IPC: B65H51/22
Filed: 1988-07-01
Abstract: Thread storage and dispensing device, where feed elements (12) in the storage drum (8) of a hub body (16), positioned eccentrically and obliquely relative to the storage drum and to the drive shaft (5, 13), sway eccentrically in the operational mode in order to separate and move forward the thread spirals on the storage drum, and where an adjusting device is provided for adjusting a sleeve (18, 18', 18'') carrying the pivoting hub body (16) in order to modify the forward feed or to adapt the forward feed to the direction of rotation. Said sleeve is supported in a pivotally adjustable manner, with one of its axes on a first point of articulation (M) and with its opposite end on a second point of articulation (P), both situated on the drive shaft. The second point of articulation (P) either slides in a rotating manner around the axis of the drive shaft and relative to the drive shaft or with an angular displacement relative to the eccentricity (e) and obliquely relative to the axis of the drive shaft, or tilts relative to an adjusting axis cutting obliquely through the drive shaft and in approximate alignment with the eccentricity. Moreover, the sleeve (18') can be fixed to rotate with the drive shaft (5, 13) by means of an adjusting axis intersecting the drive shaft axis (6) at a near right angle and in approximate alignment with the eccentricity (e) and can pivot in an adjusting plane containing the drive shaft axis; alternatively, the eccentricity (e) can be shifted from one side of the axis (19) to its other sides, the oblique axis of the sleeve being fixed as regards its angle and its rotating position relative to the drive shaft (5, 13). Precise adjustment of the forward feed or adaptation to the direction of rotation is thus achieved by a simple design.

Patent DE-3829846-A1 (DE)
IPC: B23Q3/16
Filed: 1988-09-02
Abstract: In a measuring device for the accurate measurement of the spindle pulling forces of machine tools, a test shaft (2a) having a shaft section lying behind a steep-angle taper (9a) forms a tubular measuring body (10a) which, like an elastic expanded bar, experiences under the pulling forces occurring only an exceptionally slight longitudinal strain which, however, can be readily represented on a measuring device via resistance strain gauges (27 to 30) of a measurement transducer (26). The test shaft (2a) is essentially formed by a one-piece rotary body which needs only to be provided with the measurement transducer (26), covered by a protective casing (33) and lying insulated in embedding (32), connecting leads (34), a front connector part (47) and the protective casing (33). This results in a very simple, easy-to-manipulate means of testing the said pulling forces, which means is in addition essentially unrestricted by displacement and is therefore very accurate. <IMAGE>

Title: Regenerative device for the separation of soot from the exhaust gases of diesel engines
Inventor: BAYER JUERGEN ING GRAD
IPC: F01N13/14
Filed: 1988-10-28
Abstract: A regenerative device (111) for the separation of soot from the exhaust gases of diesel engines has a fixed housing (112) for feeding and removal of the exhaust gases at the housing ends, a filter device (113), which has a drum (141), rotatably arranged in the housing and provided with elongated, tubular filter elements (153), which drum is subdivided into sectors (152) divided off from one another, a regeneration device (127), which has a burner, held on the housing, (112) and to which one of the drum sectors (152), provided with the filter elements (153) can be assigned in succession, and a circumferential sealing device (161) between drum (141) and housing (112). So that such a regenerative device (111) ensures an optimum sealing between drum (141) and housing (112) even and especially in the case of a high exhaust gas rate of feed and a relatively high soot deposit level of the filter elements (153), it is proposed that the sealing device (161) be provided with annular sealing elements (162; 166) acting on one another in an axial direction, of which the one sealing element (162), rigidly connected to the drum (141) held axially movable, by reason of a pressure drop produced in the filter device (113) is subjected to a differential pressure thereby acting on the drum axially towards the other sealing element (166) connected to the housing (112), and that the other sealing element (166)... exhibiting a spring force...

Abstract: A hydraulic brake system comprising a master cylinder 1 having working pistons 5 and 6 and working chambers 7 and 8 is provided with solenoid valves 22 in pressure fluid lines 20, 21 between the working chambers 7, 8 and a supply reservoir 14 and a switch for sensing the rest position of a brake pedal energises the valves 22 to establish a short term pressure fluid connection to replenish the reservoir 14 and relieve system pressure when the brake pedal is at or near to its rest position. In this manner, the hydraulic connection of the reservoir 14 to the working chambers 7, 8 is constituted solely via electromagnetically controllable connections, thereby obviating the need for a breather bore or central valve. In a modification the valves 22 are omitted and the replenishment of the reservoir is effected through the inlet and outlet valves 12, 15 which latter are switched open. Expansion of the brake fluid can be detected by a temperature, pressure or noise sensor and causes opening of the valves 22 or 15. The system is particularly suitable for anti-skid and traction-slip control. <IMAGE>
