Patent GB-2240257-A (GB)
Title: Safety belt reel
Inventor: SCHMIDT THOMAS
IPC: B60R22/36
Filed: 1991-01-07
Abstract: A safety belt roller has a belt winding shaft (11) which can be displaced radially into a blocking position, and which can also be coupled to a tightening device. The tooth spaces 24 between the teeth 25 of a blocking toothed arrangement 19 that is fast with the belt winding shaft 11 are provided with a flexible cover arrangement 26 for the formation of a smooth outer circumference so that when tightening takes place in an emergency by means of cable drive 21, the teeth 25 do not engage with the fixed teeth 18 of the reel housing. However, once tightening has occurred, the reel shaft and the teeth move radially, rupture the cover and allow engagement of teeth 25 and 18 and thus blocking of the rotation of the reel against unwinding. <IMAGE>

Abstract: A system for acquiring and processing seismic data comprises source-means for generating sound waves and receiver-means for recording as data those waves as reflected from sub-surface interfaces, and means for processing the recorded data to generate sets of actual data each individually associated with specific sub-surface reflection points, order the data-sets in accordance with receiver and source-means separation, process each data-set to generate additional data intermediate the recorded data, and reorder each data-set and additional data in accordance with receiver and source-means separation for further processing. Each data-set is applied to a filter eg a sinc filter to generate said additional data intermediate of the recorded actual data. The recorded actual data is also subject to traveltime correction (for example NMO). Data collection may be by use of a single shot source and a plurality of receivers which are equi-spaced, linked in a linear array, and movable above a surface to be surveyed. The data-sets may comprise common receiver or common shot gathers and the described techniques are applicable to other forms of seismic data gathers.

Patent GB-2300092-A (GB)
Title: A multilevel trellis coding method
Inventor: LIN MAO-CHAO
IPC: H04L27/18
Filed: 1995-04-18
Abstract: The method employs a single binary convolutional code to encode all the levels and is called a single-stage multilevel trellis coding, or can be generalized by combining several single-stage multilevel codings together to form a multilevel trellis coding for which the number of stages is less than the number of coding levels. One or several binary convolutional codes are processed by a multilevel belay processor and a signal mapper to select a signal point in the signal space. Decoding uses the Viterbi algorithm. Trellis coded modulation systems and binary trellis coding systems which are designed by the aforementioned trellis coding method are better than the currently known coding systems if the communication channels are additive white Gaussian noise (AWGN) channels.
