Title: Digester screen switching
Inventor: RICHTER JOHAN C F C
IPC: D21C7/14
Filed: 1991-04-25
Abstract: DIGESTER SCREEN SWITCHING          ABSTRACT           In a continuous digester for paper pulp (comminuted cellulosic material), abrupt variations in high pressure steam flow are minimized.  First and second vertically spaced annular screens are provided in a vertical vessel.  Each has an annular header associated with it and first and second circumferentially spaced liquid outlets associated with each header.  The first outlet for the first screen is generally vertically in line with the first outlet for the second screen, and the second outlet of the first screen is generally vertically in line with the second outlet of the second screen. Simultaneous withdrawal of liquid from the first outlet of the first screen and the second outlet of the second screen takes place, and then is terminated, and then simultaneous withdrawal of liquid from the second outlet of the first screen and the first outlet of the second screen takes place, and then is terminated.  This withdrawal sequence is repeated continuously.  Each header is divided into two substantially equal volumes by vertical walls with an outlet provided at the circumferential center of each volume.  Any material that passes through the screens flows under the force of gravity from the Vertical Walls to the outlet associated with that header volume due to the provision of downwardly sloping bottom portions in each volume.

Title: Gefra adiabatic combustion engine
Inventor: FRATZL GERHARD F
IPC: F02B75/22
Filed: 1991-10-21
Abstract: "GEFRA" ADIABATIC COMBUSTION ENGINE     ABSTRACT     All internal combustion engines suffer from poor thermal efficiency.    This invention centres around novel design ideas which prevent thermal losses or recover heat for reuse in the combustion process.    In addition, frictional losses are kept very low by limiting the number of moving parts to the absolute minimum necessary to operate the engine.    Light weight parts and the absence of cooling media with all their mechanical components account for a much improved power to weight ratio.    The invention consists of a modified two cycle internal combustion engine of radial design.    Cylinders are arranged around a central crankshaft on which all the piston-connecting rod units share a common journal.    Dual purpose cylinders, with their respective piston-connecting rod units, are instrumental to recapture waste heat from the combustion process for recycling.    The modular design of the cylinder piston units has the advantage that a standard housing can be fitted with the number of cylinders to meet different power requirements.     GEFRA Engine    Inv.

Title: Enhanced acoustic calibration procedure for a voice switched speakerphone
Inventor: ERVING RICHARD H
IPC: H04M1/60
Filed: 1991-11-13
Abstract: An acoustic calibration circuit in a voice switched adaptive speakerphone accurately determines the type of acoustic environment of both large and small rooms having either harsh or favorable acoustics. The calibration circuit determines the acoustic environment of a room by emitting a tone burst through aloudspeaker associated with the speakerphone and generating an echo decay parameter that is indicative of the duration of echoes from the tone burst signal measured with a microphone also associated with the speakerphone. The echo decayparameter is generated from a composite representation of the acoustic response for those echoes having the largest returned amplitude level measured at each one ofmultiple predetermined time intervals by the calibration circuit. By examining the amplitude levels in the composite representation at selected ones of the multiple predetermined time intervals, the echo decay parameter or estimate for the additional time required for the echoes to dissipate to a desired level is generated. If after performing a first measurement of the room acoustics at a prescribed first time period, the calibration circuit determines that the room echoes have not dissipated to an acceptable level in this first time period for generating a satisfactory echo decay parameter representative of these echoes, the calibration circuit regenerates the tone burst into the room a second time and then measures the resulting level of the acoustic response over an extended time period. From the echo decay parameter and the composite representation, a time-domain acoustic response is generated. Thistime-domain acoustic response provides an estimate of both the maximum returned amplitude and expected duration of the echoes. This information is then used by the speakerphone in adapting its operating parameters. If the room acoustics are harsh, the speakerphone adapts by keeping its switching response comparable with that of a typical analog speakerphone. If acoustics are favorable, however, it speeds up the switching time, lowers both the break in thresholds and the total amount of inserted switched loss.

Title: Energy transfer unit for a pile driver
Inventor: BERMINGHAM PATRICK
IPC: E02D13/10
Filed: 1992-01-14
Abstract: An energy transfer unit is designed for use in conjunction with a pile driving that has an impact block projecting from the lower end of the hammer casing and axially movable therein for transmitting energy from the hammer to a pile to drive the pile.          The unit comprises a housing for rigid attachment in axial alignment with the casing of the hammer, the  housing receiving and guiding the projecting portion of the pile driver impact block for axial movement therein.  A striker plate is guided for axial movement in the housing and is adapted to be impacted by the impact block and to transfer and distribute the impact force from the pile driver evenly and directly to the head of the pile.  Cushioning rings within the housing prevent impact between said striker plate and the pile driving hammer housing upon rebound of the pile, and thus prevents damage to the pile driver.  The cushioning rings are formed of rubber and are carried at the upper end of the housing by a retainer ring which is engaged by the striker plate when it rebounds.  Thus the rebound energy is absorbed by the rubber rings.
