Patent GB-2290878-A (GB)
Title: A photographic production method
Inventor: HAND PHILIP AUGUSTINE
IPC: G03B27/73
Filed: 1994-07-01
Abstract: A photographic production method involves calibration of a video analyser (16) and of a printer (A) using the same reference negative which has a photograph and colour sample. A densitometer is used for adjusting colour settings of the printers (A) and visual inspection by a skilled operator is used for in putting adjustment to the calibration settings of the video analyser (16). Proofs are printed at a printer (P) under control of a controller (25) which receives analysis data (39) from the analyser (16) and instruction data (45). Proofs (61) are visually inspected carefully and revised colour data is inputted (62) to overwrite the original colour data generated in the first pass (39). Final instructions are received (64) and data is inputted (65) for direct printing a printer (A) of the final photographs (66). This avoids the need for re-analysis and provides a very quick and high-quality service. <IMAGE>

Title: High pressure seal
Inventor: BAUGH JOHN L
IPC: E21B33/10
Filed: 1994-10-14
Abstract: A seal useful for high temperature and high-differential pressures, particularly in sour gas wells, is disclosed. The preferred embodiment of the seal (56) is an elongated member having features akin to a chevron-type seal (70) at, at least one end, coupled with at least one interference seal (64). A pocket (68) is created in between these two elements (70, 64) which can trap atmospheric pressure, thereby enhancing the ability of downhole well fluids to compress the seal against a mandrel (10) for facilitating its installation in a liner bore. The additional structural rigidity provided by the variety of alternative designs presented overcomes the tendency of the chevron portion (70) of the seal to fail due to downhole fluid pressures, displacing the chevron portion (70) out of shape prior to its insertion into a liner bore. <IMAGE>

Patent GB-2296165-A (GB)
Title: Multiplex communication
Inventor: GUINAND PAUL SCOTT
IPC: H04H20/74
Filed: 1994-12-15
Abstract: An orthogonal frequency division multiplexing communications system (OFDM) comprises broadcast service providers 400, earth stations 100, repeater satellite stations 200, and receivers 300 (for example mobile receivers). The size of the multiplex signal can be increased by adding extra channels. This is done by varying the number of subcarriers present in the multiplexed signal, and periodically specifying in a predetermined subcarrier the number of subcarriers present in the multiplex signal. The spectral efficiency of the system may be improved using side-lobe attenuation. Other features include reducing the peak-mean power ratio of the multiplexed signal, decoding convolutionally encoded interleaved signals and various frequency acquisition circuits. <IMAGE>

Title: Sequential isolating circuit breaker and actuator
Inventor: MCKEAN BRIAN
IPC: H01H33/666
Filed: 1995-02-20
Abstract: A circuit breaker comprises a vacuum interrupter and an isolator in series combination, the vacuum interrupter providing fast interruption of current and the isolator providing a large gap when in the open condition for additional safety and protection against transients. The circuit breaker may be operated by a single actuator device and is adapted to provide sequential isolation first by the vacuum interrupter, followed by the isolator to a fully open circuit condition, and on closing is adapted to first close the isolator under a no-load condition followed by closure of the vacuum interrupter to resume current flow. The isolator additionallly provides for the single actuator device to slowly close the isolator with low force and to quickly close the vacuum interrupter with high force. An actuator mechanism also provides further control of the relative speeds of closure of the isolator and vacuum interrupter.

Title: Autoclave door release method and apparatus
Inventor: BRAKE STEPHEN JOHN
IPC: B01J3/00
Filed: 1997-03-13
Abstract: An autoclave has a pressure sensor 20 and a door sensor 6. When pressure in the chamber 2 rises before the door 5 has been fully closed, the autoclave turns on a pump 12 to reduce pressure in the chamber. When pressure has fallen below atmosphere, a valve 17 is opened to allow air to enter the chamber through a filter 16 and equalize pressure inside and outside the chamber. Rapid release of a jammed or partially closed autoclave door is therefore possible, without risking contamination of filter 16.
