Abstract: A system (method and apparatus) are disclosed for detecting pressure surges in a turbo-compressor. Either the gas flow rate or gas velocity is measured at the intake or the outlet port of the compressor to produce a signal X. The rate of change of this signal X is determined and represented by a signal Y. The occurrence of surge is sensed and indicated by an output signal Z when the signal Y exceeds a prescribed threshold value.

Abstract: The machine has a spindle which in its free end has a chucking fixture, designed as a collet. The chucking fixture is intended for a tool which can be fed into position and removed by a tool changing device. In this arrangement, a draw bar actuating the collet by axial displacement is guided in the spindle, and the tool, in each case on the spindle side, has a tool holding head with a centring taper in an inverted frustum shape, which centring taper can be gripped from the rear by the collet in its chucking position with a conical inner surface in order to clamp the tool against the spindle. The novel tool holding device according to the invention is characterised in that the collet (7) is provided with at least one T-shaped grooved portion (72) open on one side, in that the spindle end (2') has a T-shaped or rectangular grooved portion (22) at least on one side, and in that the grooved portions (72, 22) of collet (7) and spindle end (2') can be positioned in alignment with one another in such a way as to permit the tool holding head (1) to retract and extend from the side and respectively to the side. The tool change is simplified and accelerated by the invention.

Abstract: To determine the relative measure for the difference between rotating-field and rotor speed of induction machines, the nonlinearity effects of the magnetisation characteristics of ferromagnetic materials are utilised. At the terminals of induction machines, slip- proportional current and/or voltage signals, among others, can be detected which, by suitable signal processing measures such as frequency conversion and filtering, supply a frequency-proportional measure of the slip which can be supplied to a measuring or processing circuit. <IMAGE>

Abstract: In an open-end spinning device, a subdivided fibre feed channel extends from the opening-roller housing (6) into the rotor cover (3). The first part (40) of the fibre feed channel (4) is located in the opening-roller housing (6), whilst the second part (41) is cast into the rotor cover (3). This second part (41) has, within the rotor cover (3), two length portions (410, 411), the centre lines (M1, M2) of which form an obtuse angle ( alpha ). The two length portions (410, 411) have their smallest cross-section at the point of transition (S2) from the first length portion (410) to the second length portion (411) and widen in the direction of their ends facing away from one another. To produce the part (41) of the fibre feed channel (4) located in the rotor cover (3), two cores are introduced into the casting mould and are brought to bear with their endfaces against one another. At the same time, the dimensions of the cores are so calculated that they have their smallest cross-section in the region where they bear against one another. After the casting has been completed, the cores are drawn out of the fibre feed channel (4) in opposite directions. <IMAGE>

Abstract: An adjustable-width seating unit for a passenger-carrying vehicle has a pillar (8) pivotally connected to its support frame (1, 2, 3) to swing about a first axis substantially longitudinally disposed with respect to the seating unit, an armrest (9) mounted on the pillar and rotatable relative to the pillar about a second axis, fixed relative to the pillar and substantially longitudinally disposed with respect to the seating unit. On swinging the pillar about the first axis the armrest may be moved between laterally-spaced positions and by rotating the armrest about the second axis its angular disposition relative to the seating unit may be maintained. 
     A detent (38) adjacent to the pivotal connection of the pillar to the frame locates the pillar positively but releasably in its respective positions and a detent (28) adjacent to the rotational mounting of the armrest similarly locates the armrest (9) in different angular positions relative to the pillar. The arrangement can be such that both detents may be released in a single action. 
     An adjustable-width seating unit may have at least two such armrests, spaced apart laterally to define a seat between them, the width of which can be varied by moving at least one of the armrests between laterally-spaced positions. 
     If a back support part (6) of the seating unit is reclinable, with the usual locking means for fixing it in any desired angular position with respect to the support frame, a device may be included for de-activating the locking means in a selected position of the pillar.

Date Jul. 28, 1988.An eccentric gear comprising a stationary gear wheel (2) and an eccentric gear wheel (9). The eccentric wheel is freely mounted on the input shaft and is driven round by eccentric means (4, 6) causing the eccentric wheel to roll round the internal teeth on the stationary wheel. A driving dog transmits the slow rotation of the eccentric wheel to an output shaft (14). Distinguishing for the invention is that the teeth are corrected such that the eccentric wheel is adjusted with the aid of the two eccentric means such that there is practically no backlash. A computer calculated least clearance between respective top lands on the teeth is obtained with respect to tooth meshing. The eccentric means comprises two cylindrical sleeves arranged eccentrically one in the other. At one end part of each of the sleeves, one of which is arranged eccentrically in the other, there is a radially outstanding tongue (5, 7). These tongues serve as counterweights balancing the imbalance moment of the satellite gear wheel which is due to its eccentric mounting on the input shaft. Backlash and play are eliminated by turning the sleeves of the eccentric means relative to each other.
