Title: Environmental control system condensing cycle
Inventor: WARNER JOHN L
IPC: B64D13/08
Filed: 1991-06-11
Granted: 1994-10-25
Abstract: ENVIRONMENTAL CONTROL SYSTEM CONDENSING CYCLE                    ABSTRACT      In an air cycle environmental control system, a condenser (46) removes water vapor from compressed, ambient, supply air (9) before it is expanded in a first turbine (24).  The chilled outlet air (49) from the first turbine (24) is then used as coolant in the condenser (46), absorbing there the heat of vaporization of the condensed water vapor.  After passing through the condenser (46), the warmed coolant is then expanded in a second turbine (26). Should the pressure of the supply air fall below predetermined levels, portions of the cycle that degrade performance or become unnecessary are bypassed.

Title: Communications device with voice recognition and movable element control interface
Inventor: METROKA MICHAEL P
IPC: H04M1/02

Granted: 1995-11-28
Abstract: A portable radiotelephone with an integral voice recognition circuit is disclosed. Control of the voice recognition circuit is achieved with a foldable housing element (104) which, in a closed position, covers an external keypad (110) and control buttons. When the foldable housing element (104) is in an open position, the portable radiotelephone is placed in an off-hook condition, the voioe recognition circuit (432) is activated, and the acoustic transducers (320, 424) are coupled to the voice recognition circuit (432). When the foldable element (104) is in a closed position, the portable radiotelephone is placed in an on-hook condition, the voice recognition circuit (432) is deactivated, and the electroacoustic transducers (320, 424) are coupled to the radiotelephone. A rapid closing and opening of the foldable element (104) results in the voice recognition circuit (432) being deactivated while the portable radiotelephone remains in the off-hook condition.

Granted: 1995-01-10
Abstract: In a screw holder in which bands of synthetic resin are disposed on one side of a series of screws out of alignment with the line connecting the center of each screw to stabilize the feed of the screws by the feed pawl of a screwdriver, the screws are driven in the right position regardless of the presence of the bands.  A series of screws having an enlarged head are held between a pair of bands of synthetic resin.  While a substantially straight main band having a larger cross-sectional area than a secondary band maintains the strength of the screw holder, a secondary band is allowed to bend according to the profile of the screw held therebetween.  The outer surface of the main band is flat, whereas an intermediate part between adjoining screws where the two bands meet is flattened without forming a rib-like projection therein.          Each screw is caused to bite in the main band to reduce the thickness of its bitten part.

Granted: 1998-11-03
Abstract: A finely divided chloride process titanium dioxide prepared without the use of a dispersing agent.  The slurry is dewatered via filtration, and the resulting filter cake is made flowable with an anionic dispersing agent.   In order to  attain  a  filter  cake with  very  high  solids content, the slurry should contain no, or only very few, multivalent anions.  The conditions regarding the content of  multivalent  anions  of  the  slurry  are  achieved  by selection of suitable dechlorinating agents,  especially hydrogen peroxide.  The filter cake is thixotropic and is made flowable by the fact that it is put into the "diluted" dispersing agent, especially into a part of the titanium dioxide  suspension  to  which  the  required  quantity  of dispersing agent has previously been added.   Titanium dioxide suspensions with solids content of approximately 78% are thereby obtained and are of particular use in the paper industry.

Title: Method and apparatus for controlling shift force in an automated mechanical transmission
Inventor: EDELEN STEPHEN ALTON
IPC: F16H59/04
Filed: 1994-08-10
Granted: 2000-02-01
Abstract: The shift quality of an automated mechanical transmission (10) is improved and transmission wear is reduced by controlling the armature current of the motor driving the transmission shifting mechanism (22). The current is monitored by a microcontroller (16) to determine if the shifting mechanism has encountered a snag or has stalled during a shift operation. The microcontroller (16) is programmed to control the duty cycle of a pulse width modulated (PWM) voltage signal, applied to the motor, in accordance with an algorithm which provides both proportional and derivative control of the error between the measured current and a target current. The rapid reduction in current spikes through PWM control reduces the force applied to the shifting mechanism (22) and thus the sliding clutch and transmission gearing.
