Inventor: KARP JAMES MITCHELL
IPC: G11B20/18
Filed: 1990-03-08
Abstract: A record medium, such as a magnetic tape, optical disk, magnetic disk, and the like stores data signals and error redundancy signals. Re-synchronisation signals are interleaved between the recorded signals such that the error redundancy signals are usable to correct signals recorded between such interposed re-synchronisation signals wherein no error redundancy signals are recorded. Error pointing redundancy signals are recorded between all of the re-synchronisation signals for pointing to signals in error for enhancing the error correction. Such error pointing signals can be cyclic redundancy check (CRC) signals. Controls for taking advantage of the above-described arrangement are also described. Reframing and clock synchronisation controls are also disclosed.

Abstract: The intention is to avoid hysteresis, which impairs the operation of the pressure limiting valve (27). 
<??>The pressure limiting valve (27) has a valve closing member (ball 52) which is subjected on one side to a hydraulic opening force and, on the other side, indirectly to a closing force produced by a compression spring (49). In addition, a push rod (55), which passes through a sealing ring (57) and is subject to a control pressure, is capable of exerting a closing action on the pressure limiting valve (27). 
<??>When the control pressure is inoperative, the push rod (55) is pushed back by the opening of the pressure limiting valve (27) and is held in this position by frictional forces brought about by the sealing ring (57). Operating cycles of the pressure limiting valve (27) are now free of such frictional forces.

Abstract: A multimedia interface presents information and receives user commands and data for a computer system. The multimedia interface operates in parallel with another application software module, such as an expert system. To add multimedia features to the application software module, the module is modified so as to generate multimedia commands at the same time as it displays text on a text monitor (58).The multimedia commands, which are held in a queue, provide additional information in the form of video images and generated speech corresponding to the displayed text. In addition, the multimedia commands are split into at least two sets: one set which is dispatched to the user substantially immediately after displaying the corresponding text, and one set which is dispatched upon request by the user. In the preferred embodiment, the multimedia interface presents information to the user through text, graphics, video, sound, speech production, and printed output. User inputs are made through a keyboard (55) and voice recognition (186). In one preferred embodiment two data processing units (165, 230) are used: one (165) for an expert system module and one (230) for a video output processing module. Each module includes its own flat VGA display (58, 86). The video module includes a digital video controller (180) which enables it to display drawings, photographs, still and animated graphics, video stills, full-motion video and motion video with graphic overlays. An optional satellite station (224) facilitates use of the system in environments where it is inconvenient or impossible to bring the complete system.

Abstract: A method of operating a burner (10) to reduce the NO x  emissions produced thereby is disclosed. Air and gas are premixed in a manner such that excess air exists in the resulting mixture and the velocity of the mixture is increased as it passes through the burner. By increasing the velocity of the air/gas mixture, the "residence time" associated with the formation of the flame is decreased, i.e., the combustion gases are in the reaction zone of the flame for a significantly shorter period of time, reducing the production of NO x . In order to prevent the flame from "lifting-off" the burner because of the high velocity of the air/gas mixture, flame stabilizing devices (18) or techniques are utilized resulting in a high heat flux and low NO x  production.
