摘要:
A pressure plate assembly for a friction clutch includes a housing for mounting to a flywheel; a pressure plate, held in the housing with the freedom to move in the same direction as that of a rotational axis (A); a stored-energy element; and a wear-compensating device acting in the path of force transmission between the stored-energy element and the pressure plate, where the wear-compensating device has at least one adjusting element, which can move in an adjusting direction to compensate for wear. A clearance-producing arrangement includes a gripping element provided on the pressure plate, which element comes or can be brought to rest against a blocking element (fixed in position relative to the housing arrangement upon the occurrence of wear. When the housing arrangement is being attached to the flywheel arrangement, the blocking element arrives in state in which it is able to enter into a blocking interaction with the associated gripping element.

A pressure plate assembly for a friction clutch includes a housing, a pressure plate held in the housing arrangement with freedom to move axially, and a stored-energy element transmitting force along a path between the housing and the pressure plate. A wear-compensating device acting in the path of force transmission has at least one adjusting element able to move in an adjusting direction to compensate for wear. At least one spring element pretensions the minimum of one adjusting element for movement in the adjusting direction, where at least certain areas of the minimum of one spring element extend in the circumferential direction relative to the rotational axis (A). A support arrangement supports the area of the spring element extending essentially in the circumferential direction radially from the outside and/or radially from the inside relative to the rotational axis (A).

A pressure plate assembly for a friction clutch includes a housing; a pressure plate held in the housing with freedom to move in the same direction as that in which a rotational axis (A) extends; a stored-energy element; and a wear-compensating device acting in the path of force transmission between the stored-energy element and the pressure plate and/or between the stored-energy element and the housing arrangement, where the wear-compensating device has at least one adjusting element able to move in an adjusting direction to compensate for wear. A clearance-producing arrangement includes at least one gripping element, where the minimum of one gripping element has a body section, one end of which is attached to the assembly consisting of the pressure plate and the housing, between which assembly and the stored-energy element the wear-compensating device acts. The other end of the body section is designed with a blocking section projecting laterally from the body section to act on the wear-compensating device and to interact with a blocking element, which is able to shift position relative to at least part of the gripping element when wear occurs. It is in the area of its body section that the minimum of one gripping element interacts with the blocking element.

A thrust plate assembly for a motor vehicle friction clutch with automatic wear compensation includes a housing fastened to a flywheel for common rotation about an axis of rotation. An axially displaceable pressure plate is connected with the housing so as to be substantially fixed with respect to rotation relative to it and has a friction face on a side facing the flywheel. An axially acting spring device presses the pressure plate toward the flywheel via an axially acting adjusting mechanism and accordingly can clamp a driven part arranged between the pressure plate and the flywheel. At least one play sensor is guided in the thrust plate assembly so as to be substantially axially displaceable against friction. A wear detection portion of the play sensor is axially displaceable in the thrust plate assembly in response to wear and an actuation portion of the play sensor cooperates with the adjusting mechanism for allowing an axial lengthening of the adjusting mechanism in response to wear. The thrust assembly also includes at least one device for securing the adjusting mechanism against rotation.

A cluster source includes at least two separate zones, each of whose temperatures can be independently controlled. A crucible contains the species to be evaporated, and is heated to a sufficiently high temperature that efficient evaporation is achieved. A cluster formation surface is adjacent to the crucible and receives evaporated atoms from the crucible. Clusters are produced at the cluster formation surface from the evaporated atoms, and the cluster formation surface is maintained at a temperature lower than that of the crucible to encourage good formation efficiency. Optionally, a third zone can be provided for ejection of the clusters, which is maintained at a higher temperature than the cluster formation surface to prevent formation of droplets of the evaporant.

A method and a device for angle coding a guided smooth-tube projectile, by which the roll position existing at the launching can be coded irreversibly for any insertion position of the projectile in the launching tube.
摘要:
Cross-field switch tube has three electrodes to define two concentric annular inter-electrode spaces. A magnet produces a field in both spaces, which field extends out of the switch tube through the electrodes. Circuit connects electrodes so that, with one circuit polarity, the electrode on the outside of one gap is a cathode while, with the other polarity, the electrode on the outside of the other gap is cathode for offswitching a load at any point of the AC cycle.

Beam deflection apparatus 50 has first and second conductors 64 and 68 positioned transversely in the path of beam 67 and has a resistive connector 78 to be tuned to deflection amplifier 52 and transmission line 54 to provide magnetic deflection. Capacitive plates 74 and 76 are charged by the deflection current to provide substantially equal electrostatic deflection in the same direction.

Deflection of an electron beam from axis 28 is controlled by electromagnetic deflection saddle coils 24, 26. Interference with deflection by surrounding mass of lens 22 is overcome by compensation coils 42, 44. The deflection coils and compensation coils are shaped and sized so that their own conductive properties do not distort the deflection magnetic fields. This is accomplished by equalizing between the deflection and compensation coils, the change in magnetic field during coil current penetration and by equalizing the penetration time constants for both sets of windings.
