Abstract: A pump (14) having a shaft (34) and housing (32) containing pressurized system fluid variable between low pressure at pump startup and high pressure at pump opera­tion, employs a hydrostatic sealing assembly (82) for sealably and rotatably mounting the shaft (34) within the housing. In the assembly (82), both a runner (44) mounted around the shaft (34) for rotation therewith and a seal ring (84) mounted to the housing (32) have facing surfaces (64, 92) between which pressurized system fluid creates a flowing low pressure fluid film which prevents contact between the facing surfaces (64, 92) so long as a predeter­mined minimum leakrate is maintained therebetween. Pres­surized balance fluid is provided via a passage (102) through the housing (32) from the exterior thereof at a balance pressure greater than the supply pressure of the system fluid such that at both pump startup and operation, leakrates are produced between the runner (44) and seal ring (84) facing surfaces (64, 92) which are above the predetermined minimum.

Abstract: A tool-locking device with two locking discs and a common locking screw for securing a tool sleeve between the two locking discs. The two locking discs have concentric annular grooves for securing tool sleeves of the same diameter and made of a flexible material. Surprisingly, flexible tool sleeves of this type experience rotational stabilisation about their central rotational axis without a rubber core or suchlike supporting body having to be used. As a result of the rotational stabilisation, a cylindrical tool face is always retained.

Abstract: Any of several prior art word recognizers are improved by changing the speech analysis portion thereof to include a more comprehensive spectral representation which can be characterized as two-dimensional. The first dimension is the "freeze-frame" or instantaneous sample of the spectral characteristics as derived from a typical 45 millisecond sample of the speech to be recognized. The second dimension, in a sense orthogonal to the first, spans several such time frames or samples and yields what amounts to a time derivative of the spectral properties obtained in the current time frame. In the testing or processing of the input speech in comparison to the reference patterns, essentially equal weight or effectiveness is attributed to both parts of the two dimensional reference spectral pattern and to both parts of the input speech spectral pattern. That is, equal importance is attributed to the essentially instantaneous information and the time-derivative information spanning a plurality of neighboring time frames including the frame of interest. 
     Also disclosed are the use of cepstral information and time-derivative cepstral information derived from linear prediction coefficient methods and the use specifically in connected-word recognizers using level-building concepts, or in those using two-stage processing.
