Title: Eddy current crack detection systems
IPC: G01N27/90
Filed: 1982-03-11
Abstract: An eddy current crack detection system has an inductive probe coil (L) forming part of an oscillatory circuit. The coil voltage is fed to a measuring device, a change in amplitude of the coil voltage being used as an indication of a crack. In order to compensate for lift-off in the amplitude of the coil voltage, a control signal is generated related to the magnitude of lift-off, and controls the value of a variable damping resistor (RS) in the oscillatory circuit. Alternatively a variable gain amplifier may be positioned between the probe coil and the measuring device, the control signal varying the gain of the amplifier so that the output of the amplifier is maintained constant with lift off. <IMAGE>

Patent GB-2124195-A (GB)
Title: Machines for cleaning containers e.g. beer kegs
Inventor: CHAMBERLAIN CHRISTOPHER JAMES
IPC: B08B9/08
Filed: 1983-05-03
Abstract: Beer kegs 55 are cleaned by immersing them at a loading station 57 in a circular tank 54 of cleaning fluid with their filling apertures lowermost so that a hollow spike 60 on a hollow radial arm 52 in the tank can enter the aperture. The spike vents the keg so that cleaning fluid enters the keg and destroys its buoyancy and the keg then advances, with the spike still inserted, round the tank and receives ultrasonic cleaning treatment. On return to the station 57, or on arrival at a separate unloading station, the spike is pressurised via the arm 52 to expel cleaning fluid and the keg is then conveyed to a rinsing plant. A transporting carriage 71 can take an unclean beer keg from the end of an input conveyor 62, which terminates in the vicinity of the loading station, to the loading station whilst at the same time transporting a cleaned keg from that station to an output conveyor (70, Fig. 4A). Accurate centering of unclean kegs is performed by a retractable centering spike (66, Fig. 4B) associated with the input conveyor so the kegs are located accurately on the conveyor and hence faultlessly located over a spike when transported by the carriage. <IMAGE>

Title: Friction clutch for a motor vehicle
Inventor: TOMM DAGWIN
IPC: F16F15/123
Filed: 1984-09-07
Abstract: The invention relates to an arrangement for suppressing knocking noises between the toothings of the hub 15 of a clutch disc 11 and of a gear shaft 13, especially during idling. For this purpose on the clutch hub there is held a component 35 which engages with radially resilient tabs 37 in the tooth gaps of the toothing of the gear shaft 13. This component produces a force- effected connection between hub and gear shaft and is capable of transmitting the torques which occur in idling. In order to improve the disengagement behaviour of the clutch after fitting of the clutch disc, this component 35 is braced in the axial direction so that it exerts a force acting in the disengagement direction upon the hub of the clutch disc. In order to adjust the bracing automatically, on one of the cover plates 33 of the clutch disc which twist in relation to the hub on torque loading there are provided tongues which axially displace the component by means of oblique faces. Thus the component comes to abut on a surface of the hub, whereby a precise, predetermined initial axial stress can be maintained. <IMAGE>
