Title: Positional tracking of an information record track
Inventor: YARDY RAYMOND
IPC: G11B21/10
Filed: 1980-03-24
Granted: 1984-05-17
Abstract: A servo control apparatus for maintaining a scanning device, such as a beam of radiation, aligned with an information recording track on a moving recording medium, such as a record disc. The apparatus is especially adapted for use in correcting for tracking deviations brought about by temperature-induced expansion and contraction of the disc, which causes the recording track being scanned to move radially outwardly or inwardly relative to the beam of radiation. In the preferred embodiment, the apparatus includes a movable mirror for oscillating the beam in a radial direction, in accordance with a periodic dither signal. This causes a corresponding variation in the intensity of the beam reflected by the disc, with the amplitude and phase angle of this intensity variation, relative to that of the dither signal, indicating the direction and magnitude of the deviation of the beam from the track centerline. Whenever the magnitude exceeds a prescribed level, a step forward or step reverse pulse signal is coupled to a stepper motor, to increment the beam in the appropriate radial direction, whereby the beam is maintained substantially aligned with the centerline of the recording track.

Title: Method and apparatus for sterilizing a medical unit
Inventor: HEILMANN KLAUS
IPC: A61L2/18
Filed: 1990-11-02
Granted: 1992-08-20
Abstract: The invention relates to a process for sterilising a medical assembly group with at least two connections for coupling to a liquid stream of a medical device, in which a sterilising medium flows through the assembly group. 
<??>Medical assembly groups of this type are, for example, medical filters, in particular dialysers. They require a high degree of sterility. This is achieved by the process steps below: 
 
  a. Introducing the assembly group into a system with pressure-tight coupling of the two connections to a delivery and removal line of the system under atmospheric conditions, 
  b. Allowing the sterilising medium from the system to flow through the assembly group for a predetermined period, 
  c. Closing the two connections in a germproof manner in the coupled state, without these being opened after sterilisation is complete, 
  d. Removing the assembly group from the system as a sterile unit with closed connections. 
 
<??>All the process steps up to and including the removal of the assembly group are therefore carried out in a system in which the sterility obtained is maintained at all times. This "in-line sterilisation" guarantees a high sterility of the medical assembly group treated. 
<??>The invention furthermore relates to the appliance for carrying out the process.
