Patent DE-3160625-D1 (DE)
Title: Rotary fluid seals
Inventor: JOHNSTON DAVID ERNEST
IPC: F16J15/32
Filed: 1981-03-10
Granted: 1983-08-25
Abstract: A rotary fluid seal, especially an oil seal for a rotary shaft, comprises a sealing ring between axially-opposed divergent frusto-conical counterfaces of relatively rotatable members, preferably casing rings in a self-contained seal unit, the sealing ring having a pair of divergent sealing lips presenting frusto-conical contact faces to the counterfaces and being substantially coaxial with but floating freely between the relatively rotatable members, the contact faces bearing frictionally on the counterfaces so that, on relative rotation of the members, the sealing ring is frictionally driven into rotation by one or other of the members and the effect of centrifugal force, tending to cause the sealing lips to flex angularly outwardly, reduces the bearing load of the contact faces on the counterfaces.

Title: A non-woven tube for membrane filtration and method of forming same
Inventor: VAN ZON CORNELIS
IPC: B29C65/08
Filed: 1982-11-25
Granted: 1987-07-23
Abstract: A composite tube of a heat-sealable non-woven material comprises an inner and an outer tube of non-woven, each of said tubes being provided with a longitudinal seal obtained by ultrasonic sealing, the outer and inner tube being fixed with respect to each other by adhesive spots. The inner side of the inner non-woven tube is coated with a membrane for membrane filtration. The seal formed by ultrasonic sealing in the outer tube does not extend to the inner side of the inner tube and preferably the seals in the outer and inner tube are staggered with respect to each other. The composite tube is formed by first forming the inner tube, applying spots of an adhesive upon the outer side of the inner tube, and subsequently applying the outer tube onto the inner tube. During the step of forming the longitudinal seal by ultrasonic sealing in the outer tube it is avoided that the seal as formed extends toward the inner side of the inner tube.

Abstract: A method and apparatus are provided for adsorbing water vapor or other first gas from a mixture thereof with a second gas to reduce the water vapor or first gas concentration in the mixture to below a permissible maximum concentration, in which the advance of the leading edge of the adsorption front in a sorbent bed is detected by sensing the advance of the temperature front that precedes the adsorption front, and this advance is detected by sensing the temperature of the sorbent bed sufficiently far from the end of the bed to prevent the temperature front from leaving the bed, using a temperature sampling probe; when the temperature front reaches this point, the adsorption front is still a distance away, since it follows the temperature front, and the adsorption cycle is discontinued, and the bed regenerated; the regeneration cycle can similarly be controlled independently, to be terminated when regeneration is complete, as detected by advance of the temperature front in the opposite direction.

Title: Voice messaging system with unified pitch and voice tracking
Inventor: DODDINGTON GEORGE R
IPC: G10L25/93
Filed: 1984-02-29
Granted: 1988-10-13
Abstract: A voice messaging system, wherein linear predictive coding (LPC) parameters, pitch, and preferably other excitation information is derived from a human voice input, encoded, and transmitted and/or stored, to be called up later to provide a speech output which is nearly identical to the original speech input. 
<??>The residual signal derived from LPC estimation is adaptively filtered, and then is used as the input to a conventional pitch estimation procedure. The adaptive filtering step uses the first reflection coefficient (k1) to realize a simple filter (e.g., A(z) = (1 - k1 z-1)-1). This filter removes high frequency noise from the residual signal during voice periods, but does not remove the high frequency energy which contains important information during the unvoiced periods of speech. 
<??>Preferably the above preprocessing technique is also combined with a postprocessing technique, wherein dynamic programming is used to optimally track pitch and voicing through successive frames.
