摘要:
A variator for ratio adjustment of a continuously variable chain drive transmission having one variator shaft (1) and one variator pulley (2) supported upon the variator shaft (1) and axially movable by pressurizing a variator pressure chamber (31). The variator shaft (1) has on one end an axial hole (10) through which the variator pressure chamber (31) and a second pressure chamber (8) can be loaded with pressure independent of each other. The pressure is supplied to the variator pressure chamber (31) via a first section (13) of the axial hole (10) and the pressure is supplied to the second pressure chamber (8) via a non-rotating pipe (7) and a second section (15) of the axial hole (10), the pipe (7) is situated within the first hole section (13). It is proposed that the pipe (7) has two axially adjacently disposed sealing rings (73) for reciprocal dynamic sealing of the pressure supplies to the variator pressure chamber (31) and to the second pressure chamber (8) and that the variator shaft (1) has a vent hole (9) discharging, on one side between the two sealing rings (73) and on the other side in a transmission inner space (94).

A transmission device has at least one electro-hydraulic transmission control unit and a method of operating the transmission device having a plurality of gear wheel that can be engaged and disengaged from a force flow by fluidically actuated shifting elements. A piston space of a first shifting element, delimited by a second functional surface of the actuating piston of the first shifting element, is made separate from a piston space of a second shifting element, delimited by the first functional surface of the actuating piston, and an area of the second shifting element, that carries an actuating pressure, or an area of the first shifting element, that carries an actuating pressure, is, or can be, connected to the piston space delimited by the second functional surface of the actuating piston of the first shifting element.

A method and device for controlling an extracorporeal blood treatment apparatus, which can be operated as a hemodialysis apparatus, hemofiltration apparatus or hemodiafiltration apparatus, are disclosed. The method and device make provision, apart from balancing the fluids as a function of the weights of the containers, for the measurement of the weight reduction or increase of at least one of the containers in the time interval in which the pump assigned to the respective container performs a preset number of revolutions or pump strokes. The change in the weight of the container for a half or one pump revolution can be determined. The delivery rate of the respective pump is ascertained from the measured weight reduction or increase in the specific time interval, thereby permitting the precise determination of the actual delivery rate of one or more pumps. The actual delivery rates of all the pumps are preferably monitored.
摘要:
A transmission device (1) with a hydraulic system (4) comprising a main transmission pump device for supplying various transmission components with hydraulic fluid. The main transmission pump device is driven by torque applied to the transmission input shaft (2). A force flow between the transmission input shaft (2) and transmission output shaft (3) is produced by various hydraulically actuated transmission components. When the hydraulic system (4) is not supplied by the main transmission pump, the force flow is interrupted. The hydraulic system (4) has an auxiliary pump device (5) by virtue of which the hydraulic system (4) too can be supplied with hydraulic fluid. The auxiliary pump device (5) is driven by torque applied to the transmission output shaft (3) at least when the force flow is interrupted.

摘要:
At least first and second terminals are connected to a packet-oriented network, with real-time critical data being transmitted via payload data frames from the first terminal to the second terminal. In cases in which no real-time critical data is available for transmission, fill frames signaling this fact are transmitted at a minimum transmission rate from the first to the second terminal. The transmission quality is determined by taking into consideration the payload data frames and fill frames received at the second terminal within a particular period.

A method and device for the removal of balls from a supply is disclosed. The device has a horizontal plate having one or a plurality of circular orifices of identical size in the form of transcurrent orifices running vertically from the upper side to the lower side. The plate on its upper side exhibits a depression around each orifice, in conjunction with which the base of the depression are curved, the periphery of the depression exhibits an elliptical, oval or spindle-shaped form at the level of the surface of the plate, the mid-point of the orifice in each case lies on the mid-point of the longitudinal axis and the transverse axis of the periphery of the depression, and the base of the depression is inclined towards the mid-point of the orifice along the longitudinal axis.

A method and an apparatus are proposed in order to bond multilayered substrate packages over a large surface at uniform heating in the course of one single work step, wherein the structured substrates are to begin with aligned to one another with high precision to correspond to the structuring in a working area separate from the heating apparatus.
摘要:
In a motor vehicle having equipment parts in the front-occupant area which can be adjusted on separate sides, two operating modes are possible. In a conventional operating mode, the adjusting of the equipment parts on the front passenger's side takes place individually corresponding to the front passenger's presettings. In the other operating mode, the adjusting of the equipment parts on the front passenger's side takes place synchronously with the adjustment of the equipment parts on the driver's side corresponding to the driver's presettings. The selection of the two operating modes takes place automatically or arbitrarily.
