Patent GB-2289414-A (GB)
Title: Cryosurgical instrument
Inventor: GODDARD ROBERT WILLIAM
IPC: A61B18/00
Filed: 1994-05-10
Abstract: The instrument comprises a metal cooling tip 50 operable to be cooled by a flow of a cryogenic fluid within the tip, at least a part of the exterior of the tip being coated with a heat-insulating coating 270 such as PTFE. The presence of the heat-insulating coating can promote nucleate boiling of the fluid rather than film boiling. Nucleate boiling within the tip provides a greater cooling efficiency of the tip than film boiling. <IMAGE>

Patent GB-2332790-A (GB)
Title: Sync detection device
Inventor: SHIM JAE-SEONG
IPC: G11B7/004
Filed: 1998-06-02
Abstract: A sync detection device for an optical disk player stops generating sync insertion signals, when a sync detection signal is normally generated after a sync protection window signal is out of sync with the sync detection signal. A sync insertion and protection device 232 sets a sync protection window according to a sync detection signal from a sync detector 224 in response to a reset signal, counts a playback clock to generate a sync protection window signal if the count value is coincident with a position where the sync signal is to be generated, and generates a sync insertion signal in response to a sync insertion request. A sync generator 230 outputs the sync protection window signal if the sync detection signal is in sync with the sync protection window signal, and outputs the sync insertion signal if the sync detection signal is out of sync with the sync protection window signal. A sync noise canceller 234 counts the playback clock during generation of the sync detection signal, and generates the reset signal to the sync insertion and protection device 232 if the count value reaches a predetermined value. A PLL producing the playback clock pulses (fig. 3 not shown) may include an average value calculator after the loop filter to prevent the clock from being out of sync even when a defect is detected.
