Patent EP-0368435-A3 (EP)
Title: Dehumidified air generator employing adsorbent
IPC: F26B21/08
Filed: 1989-05-02
Abstract: A dehumidified air generator (10) has a plurality of 
rotatable absorption columns (12, 14, 16) 
filled with adsorbents for gen­
erating dehumidified air which will be used to dry a plastic 
material or the like. A directional control valve for 
switching between adsorbing and regenerating steps in the 
adsorption columns comprises a slide valve mechanism com­
posed of a stator (34, 38) and a rotor (32, 36) slidably held against the 
stator. The rotor has a plurality of openings defined 
therein and communicating with inlet/outlet ports defined in 
side walls of the adsorption columns through tubes (40, 42, 44). By 
rotating the rotor in synchronism with the adsorption 
columns, the adsorbing and regenerating steps are switched 
to dehumidify, with the adsorbents, humid air introduced 
into the adsorption columns through the directional control 
valve and also to desorb the adsorbents for regenerating 
them.

environment. An outer housing 15 may preferably be 
position over the case to add further protection.

Title: High resolution, fully differential cmos comparator
IPC: H03F3/45
Filed: 1989-09-19
Abstract: A high resolution, fully differential, CMOS comparator 
advantageously employs a single high gain, "folded cascode", 
fully differential operational 
amplifier (M1-M11) and an output latch (M15, M16) 
circuit and the output common mode control of the high-gain 
amplifier is implemented without requiring the use of a 
conventional control circuit, thus improving layout economy. 
The common mode control is performed by providing the latch 
with a differential input stage (M13, M14) through which a common mode 
feedback network is realized which acts upon a pair of output 
transistors (M10, M11) of the operational 
amplifier (M1-M11) for effectively 
controlling the output common mode thereof. The comparator 
has a simplified layout and is remarkably faster because it 
has not additional capacitances loading the outputs of the 
amplifier.

Patent EP-0574797-A3 (EP)
IPC: H01L21/50
Filed: 1993-06-08
Abstract: The invention relates to the production of a pressure glass passing-through in a metal body. Such pressure glass passing-throughs are used in metal housings for semiconductors, in particular integrated circuits. These passing-throughs must hermetically seal the interior of the housing from the exterior. For this purpose, a glass bead is fused into a bore of the housing and the connecting lead of the integrated circuit is passed through the glass to the outside. It has now been found that alloys of the Cu, Al, Mg systems show, during cooling after the fusion step, a hardening effect with the result that, with these alloys, pressure glass passing-throughs can be produced which show hermetic sealing even after high thermal and/or mechanical stress. They have a high thermal shock resistance and good corrosion resistance. <IMAGE>

Patent EP-0583914-A3 (EP)
IPC: B01D3/22
Filed: 1993-08-04
Abstract: Improved catalyst-downcomer-tray assemblies for 
vapor liquid contact towers. Downcomers are constructed 
for receipt of bundles of catalyst media used to promote 
chemical reactions therein. Raised, perforated regions 
of the underlying trays are then disposed therebeneath 
for improving mass transfer efficiency. The raised 
regions reduce fluid pressure to vent excess vapor from 
downcomers and trays therebeneath. The vapor generated 
within the downcomers from the catalytic reaction may 
then be selectively directed into the liquid discharged 
from the downcomer disposed on the tray above and 
imparted with a horizontal flow characteristic. In this 
manner the catalytic reaction vapors can be effectively 
released to facilitate a stabilized vapor-liquid flow 
configuration with improved chemical reaction occurring 
in the downcomer of the process tower.

Title: Floor drying method.
Inventor: HEIM KURT
IPC: E04B1/70
Filed: 1994-07-26
Abstract: Water damage in a multi-layered building floor is eliminated by a method which makes it possible to monitor the drying. The method uses a neutron probe, with the aid of which the moisture content is determined. As a reference value, a measured value is taken on a floor of the same structure, but without any water damage. In the damaged room, at least all the room corners are then measured. The corner with the highest measured value is selected as monitoring point. During the drying process then beginning, regular measurements are taken again at said monitoring point. When the reference value has almost been reached, then the drying is interrupted. This method permits specific use of the drying implements at the damaged locations. In addition, the period of time for the repair work is shortened. <IMAGE>

Title: Method and apparatus for overlaying digitally generated graphics over an analog video signal
Inventor: ZEIDLER DAVID E
IPC: H04N5/445
Filed: 1995-05-18
Abstract: A system for overlaying digital character signals on an analog video source signal including a predetermined color subcarrier includes a subcarrier phase lock loop (14), a digital character generating device (28), a digital video encoder (18), and a switching device (24). The subcarrier phase lock loop separately generates a color subcarrier and a system clock signal which are locked to the color subcarrier of the analog video source signal. The digital character generating device detects horizontal and vertical timing of pixel information in the analog video source signal, and generates digital character signals that are to be overlaid in predetermined pixels of the analog video source signal. The digital video encoder is responsive to the color subcarrier and system clock signals for generating a separate color subcarrier which is locked to the color subcarrier of the analog video source signal. The digital video encoder also converts the digital character signals from the digital character generating means into an analog video output signal that includes the color subcarrier generated in the digital video encoder. The switching means directs the analog video output signal from the digital video encoder or the analog video source signal to an output of the system during pixels times when a digital character is to be overlaid or not overlaid, respectively, on the analog video source signal. <MATH>

Abstract: Apparatus for and method of sending a video bitstream, including a
plurality of high priority segments and associated low priority segments, by
transmitting only the low priority segments from a transmitter over a facility

storage or generated using the agreed-to format) and interleaved in real time
with the received low priority segments to recreate an interleaved video
bitstream.
