Patent EP-0250210-A3 (EP)
Title: Method of fabricating metal-ceramic composites, and metal-ceramic composites made thereby
IPC: C04B41/88
Filed: 1987-06-16
Abstract: A chemical pretreatment method is used to produce boron carbide-, boron-, and boride-reactive metal composites by an infiltration process. The boron carbide or other starting constituents, in powder form, are immersed in various alcohols, or other chemical agents, to change the surface chemistry of the starting constituents. The chemically treated starting constituents are consolidated into a porous ceramic precursor which is then infiltrated by molten aluminum or other metal by heating to wetting conditions. Chemical treatment of the starting constituents allows infiltration to full density. The infiltrated precursor is further heat treated to produce a tailorable microstructure. The process at low cost produces composites with improved characteristics, including increased toughness and strength.

Title: Circuit arrangement for providing isolation between the transmission paths of a hands-free subset
IPC: H04M9/08
Filed: 1987-08-21
Abstract: A circuit is disclosed in which the effect of ambient noise on the voice control in a hands-free subset is greatly reduced. Frequency components of the ambient noise which lie outside the voice-frequency range are determined on a selective basis and are used, together with the voice levels of the two transmission paths of the subset, to control the send path. The control signal selectively derived from the ambient noise counteracts the control by the voice level of the send path. In the simplest case, it is derived via a filter (12, 18) designed to pass the desired frequency range, an amplifier (13, 19), and a sign-reversing rectifier stage (14, 20) whose output is combined in an adder (11) with the control signal derived from the voice level.

Abstract: A mini-proinsulin in which the A and B chains are linked by the amino acid Arg in place of the C chain has insulin activity and is suitable for producing medicaments for the treatment of diabetes mellitus. It can also be converted straightforwardly with trypsin into an insulin derivative whose B chain is extended by Arg. The latter can be converted with carboxypeptidase B into insulin. However, it is also possible and advantageous to convert the mini-proinsulin directly into insulin in a one-pot process.

Title: Watchdog timer
IPC: G06F11/00
Filed: 1989-02-21
Abstract: In a watchdog timer, the selected codes identifying the format of a watchdog timer algorithm, such as the intervals within which a watchdog timer status must be issued by the host processor, are supplied as hardwired preset codes in programmable fuse or read only memory cells that are adapted to be programmed, but are immune from ESD, power glitches and errant software. A programmable code indicating a programmable time interval is also stored in a register protected from errant software when the watchdog timer is enabled. A selector receives the preset code and the programmable code and selects an output code indicating the time interval within which the watchdog timer must be reset by a processor status signal. The selector can be programmed to select only the preset code by supplying a selector control signal through an element that is immune from electrostatic discharge, power glitches and errant software. Also, a code fixing the watchdog timer in an on state can be supplied with ESD-immune cells. The watchdog timer employs a keyed sequence for the watchdog timer status signal.

Title: Modulator/demodulator apparatus
IPC: H04B3/23
Filed: 1989-04-28
Abstract: A modulator/demodulator apparatus has a first 
digital signal processor (DSP1) that is operable in 
a full duplex mode for providing digital samples to 
a coder-decoder (I0P) and receiving transmitted 
samples therefrom. The first digital signal 
processor (DSP1) is responsive to received samples 
for initiating echo cancellation in the received 
samples. A second digital signal processor (DSP2) 
is operable to demodulate samples received from the 
first digital signal processor and output 
demodulated information therefrom. An input/output 
processor (IOP) initiates operation of the first and 
second digital signal processor. The input/output 
processor receives input information to be 
transmitted and supplies that information to the 
first digital signal processor and receives 
demodulated message information from the second 
digital signal processor and outputs message 
information to one or more user devices. The 
input/output processor also receives transmitter 
digital samples which are to be demodulated from the 
first digital signal processor and supplies the 
transmitted samples to be demodulated to the second 
digital signal processor. The input/output 
processor is operable in a full duplex mode.  
     Accordingly the input/output processor acts as 
a system controller in controlling transmission and 
 
 
reception digital signal processors which provide 
independent transmission and reception functions 
suitable for a multirate modem apparatus.

Abstract: A system for controlling automatic transmissions

system, fuzzy production rules have been prepared based 
upon an expert driver's judgments and operation made on a 
vehicle with a manually shifted transmission. Various 
operating conditions including opening degree of a 
throttle valve and road speed of the vehicle are detected 
and from the detected value, various predictions are made 
such as an appropriateness of vehicle response to a 
gearshift intended by the driver and engine output change 
that would occur should the transmission be shifted to a 
given gear. These measured or estimated value are put on 
a common scale named universe of discourse and 
membership values degree of the aforesaid rules are 
successively calculated. Among the rules, one rule is 
finally selected and according to a gear position 
indicated in the selected rule, the current gear is 
shifted up or down or is held at the present position.

Patent EP-0393805-A3 (EP)
IPC: G21C15/26
Filed: 1990-01-03
Abstract: A containment cooling system (4) utilizes a 
naturally induced air flow and a gravity flow of water 
over the containment shell (6) which encloses a reactor 
core (8) to cool reactor core decay heat in two stages. 
When core decay heat is greatest, the water and air flow 
combine to provide adequate evaporative cooling as heat 
from within the containment is transferred to the water 
flowing over the same. The water is heated by heat 
transfer and then evaporated and removed by the air flow. 
After an initial period of about three to four days when 
core decay heat is greatest, air flow alone is sufficient 
to cool the containment.
