Abstract: ABSTRACT OF THE DISCLOSURE              HIGH-INTENSITY X-RAY SOURCE HAVING    A ROTATING VACUUM CHAMBER        A high-intensity X-ray source generates significant heat at the anode.  To help dissipate this heat, the anode is often rotated in the vacuum.   Heat must still be radiated  from the  anode to the exterior walls. An improved X-ray source incorporates the anode in the walls of the vacuum chamber and rotates the entire chamber.  The heat is then easily conducted to the exterior where it may be dissipated by connection or forced air cooling.

Abstract: A television picture transmission system using conditional replenishment employs a scanning rate at the transmitter which differs (for asynchronous operation, slightly; or for operation between systems using different standards, considerably) from the scanning standard at the the receiver. The frame rate conversion is effected by the updating loops at the transmitter or receiver by, respectively, periodically stopping the coding loop for a field or frame so that no data is produced to produce a lower frame rate or periodically repeating a field or frame in the loop without adding any updating data so as to produce a higher frame rate. Resulting variations in data rate are accommodated by utilising the buffering inherent in conditional replenishment systems. The jerkiness of motion in the received picture resulting from stopping the loop or repeating a field or frame can be reduced by the use of temporal interpolation in the generation of the updating data to anticipate the stopping or repeating of a field or frame, whilst conversion of the number of lines per frame can be effected by spatial interpolation using a transversal filter.
