Title: Pitch shift apparatus

Granted: 1994-02-22
Abstract: ABSTRACT OF THE DISCLOSURE         This invention is concerned with pitch shift apparatus for converting an audio signal into PCM digital data and then making a pitch shift, wherein the PCM digital data is written in a ring memory by a write address generator circuit, and read therefrom by two read address generator circuits which start to read at time points differing by an amount corresponding to 1/2 the ring memory at a certain pitch, in which case immediately before the read address on the now finally outputting side and the write address causes passing or cyclic delay, the read address on the switching-to side is stopped from increasing during the interval from a time point at which an audio signal on the switching-to side makes zero crossing to a time at which an audio signal on the now outputting side makes in-phase zero crossing, and switching is made at the zero crossing point, so that the connection of the audio signals can be smoothly made without such AM modulated component as caused in the cross fade method, enabling high-quality pitch shift to be achieved.

Title: Thermal barriers for enhanced oil recovery
Inventor: CULLICK ALVIN S
IPC: E21B43/243
Filed: 1990-11-05
Granted: 1997-07-01
Abstract: A process is described to direct heat towards a productive interval of a reservoir during a thermal enhanced oil recovery (EOR) operation.  A chemical composition suitable for producing a rigid polymer foam is injected above or below the productive interval.  Once in place the temperature of the composition is increased and it reacts to produce a foamed polymer thermal barrier.  The temperature can be increased by steam injection or in-situ combustion.  After a rigid foam is formed, thermal efficiency is increased by reducing heat losses to non-producing zones during a thermal stimulation.
