Patent EP-0064750-A3 (EP)
Title: Gapless splicing of pitch altered waveforms
IPC: G10L21/00
Filed: 1982-05-07
Abstract: A time compression/expansion system for recorded 
programs provides time change on playback with pitch 
correction free of gaps or processing noise due to splicing 
and discard. A dual memory delay system operated to 
inversely vary delay is used to provide an interval during 
which to detect the start of the next program sample with 
matched signal amplitude and sign. During this interval pitch 
correction is a continuous extension of the current sample. 
The system can include individual processing of contiguous 
frequency bands.

Patent EP-0211117-A3 (EP)
IPC: B02C19/06
Filed: 1985-08-02
Abstract: A no-moving parts pulverizer (19) and classifier 
system (15) reduces materials to one hundred fifty microns 
to less than ten microns using superheated steam or 
any gas capable of being compressed and expanded thru 
machined orifices. The resultant size reduction 
depends upon the classifier gas rate and pressure, 
the pulverizer gas rate and its pressure. These 
combinations control and regulate miximum particle 
size, average particle size and the mix of gas and 
solids in process.  
     The feedstock enters the classifier chamber (15) 
by auger (12) or similar manner as long as the feeder 
maintains a positive seal. The classifier chamber (15) 
separates the feedstock by size and particles of a 
predetermined size exit (32) the system in a specific 
ratio of gas and solids. The feedstock larger than 
specified exit the base of the classifier (15), split into 
two equal streams (20A, 20B) and accelerate thru the 
pulverizer (19). The reduced feedstock exits (13) the 
pulverizer (19), mixes with incocming feedstock (10) and again 
enters the classifier (15).  
     The system is controlled using pressure, 
temperature, feedrate or any combination of the 
three. Other control methods can be used if any one 
of the three are part of the control circuit.

Abstract: A container e.g. an aerosol container is provided with a 
fluid flow regulator. The regulator forms a flow path from 
one region to another. In the flow path is a chamber one part 
of which is deformable. Fluid passes from the container 
through an inlet to the chamber and from thence through an 
outlet. A pressure differential is created between the contain­
er and the chamber. The fluid in the container exerts 
pressure on the deformable part which deforms to in­
creasingly restrict the flow of fluid through the outlet.

Abstract: A chemically-sensitive surface plasmon resonance device 
comprises a slab (11) of a light-transmissive material (e.g. 
perspex) having a layer (14) of a metal on one side and a 
plurality of ridges (13) on the opposite side. A layer (15) of

as it leaves the slab. Exposure of the chemically sensitive 
layer (15) to an analyte causes a change, as a function of 
wavelength of reflected light, of a plasmon resonance absorption.
