Patent EP-0196364-A3 (EP)
IPC: C08G18/76
Filed: 1985-11-03
Abstract: MDI-based prepolymers are blown with a substantially 
nonaqueous blowing agent, such as pressurized air, and 
polymerized with stoichiometric amounts of polyox­
yethylene polyol having at least two hydroxyl equivalents 
per mole, yielding a hydrophilic foam. The present foams 
may be extruded, knife-coated or otherwise cast into sheets, 
or may be fabricated by other known foam preparation 
techniques. Because the foam is polyerized with polyox­
yethylene polyol instead of water, the foam exhibits both 
superior drape and improved stretch and recovery as 
compared with prior-art MDI-based flexible foams formed 
with aqueous reactants. The foam is particularly suited for 
use in external biomedical applications as, for example, a 
laminated medical/surgical dressing in which a thin sheet of 
the hydrophilic foam adheres to a nonstick aluminized veil 
on one side.

Abstract: 1. Verfahren und Vorrichtung zur pulvermetallurgischen 
Herstellung von blasenfreiem, wasserstoff- und oxidarmem 
Aluminiumhalbzeug.  
         2.1 Zur pulvermetallurgischen Herstellung von Halbzeugen auf 
Aluminiumbasis werden gasverdüste Aluminiumlegierungspulver eingesetzt. 
Oxid- und/oder Hydroxidgehalte derartiger Pulver führen zur Ausbildung 
von Blasen und einer porösen Gefügestruktur im Halbzeug. Insbesondere 
hochfeste magnesium- und/oder lithiumhaltige Legierungen, die oberhalb 
400 °C wärmebehandelt werden, verspröden sehr stark, wenn der Oxidgehalt 
an der Teilchenoberfläche bestimmte Grenzwerte überschreitet. Diese 
Grenzwerte können durch herkömmliche Vakuumverfahren und -einrichtungen 
nicht eingehalten werden. Nach dem neuen Verfahren und mit der 
entsprechenden Vorrichtung sollen hochfeste Aluminiumlegierung mit 
blasenfreiem und versprödungsarmen Gefüge auf pulvermetallurgischem Wege 
hergestellt werden können.  
         2.2 Erfindungsgemäß wird das gasverdüste Legierungspulver bei 
Temperaturen zwischen 400 und 550 °C allseitig von einem Schutzgas mit 
einer Mindestgeschwindkeit von 0,2 m/s umströmt. Dadurch entsteht ein 
dynamisches Druckgefälle, das den Abtransport der Oxide/Hydroxide 
begünstigt. Das so behandelte Pulver wird in der Wärme umgeformt und 
unmittelbar nach der Formgebung rasch abgekühlt. Es ergeben sich 
Produkte mit blasenfreiem, versprödungsarmen Gefüge und sehr geringen 
Wasserstoff- und Oxidgehalten.  
         2.3 Pulvermetallurgische Herstellung von Preß-, Schmiede- oder 
Walzerzeugnissen auf der Basis von hochfesten 
Aluminiumlegierungen.

IPC: H04N7/173
Filed: 1987-01-27
Abstract: An improved control and metering system for 
pay television distribution over a cable network. A 
control unit is located near each receiver on a subscribers 
premises and a secure filter, switching and metering 
unit is located external to the subscribers home. For 
the basic apparatus power and control signals needed 
to operate the external unit require no separate wiring 
as these signals are multiplexed over the coaxial cable 
that carries the TV signal into the home. An improved 
switch in the external unit activates a temperature 
compensated digital metering unit that displays either 
(or both) the time that the premium programming has 
been accessed or the totalized cost of the pay programming 
accessed. When implemented in high density housing 
districts common equipment is centralized and the apparatus 
is known as a switched star configuration. Also included 
is apparatus that permits metering to be accomplished 
at a central location for a community. The apparatus 
allows for tiering of pay programming utilizing different 
rates. The system is secure without scrambling or jamming. 
Another version of the apparatus permits Cable TV Operators 
to sell common carrier services to independent programmers 
according to utilization. The apparatus also allows 
 
 
for interfacing the cable TV network with a fibre optic 
television distribution network, for subscriber switching 
between the two systems and the metering of the utilization 
of such an apparatus. The system introduces the idea 
of a Fibre Optic Video Party-Line to reduce implementation 
costs.

Patent EP-0306596-A3 (EP)
IPC: G06F3/037
Filed: 1983-02-07
Abstract: A high resolution light pen is disclosed for use 
with graphic displays. More particularly, a light pen 
is disclosed having a collimation tube slidably mounted 
within a housing. The collimation tube includes an 
axially extending channel having a non-reflective 
surface. A photodetector is fixably mounted within the 
housing aligned with the channel. A lens is mounted 
adjacent the front end of the channel and has a focal 
length equal to the spacing between the lens and an 
aligned pixel of the video screen. By this 
arrangement, all light rays emanating from an aligned 
pixel and passing through the lens are refracted 
axially along the channel and directed to the 
photodetector thereby maximizing the input thereto. 
The subject invention further includes a new and 
improved discrimination circuit for determining valid 
input signals from the light pen and producing an 
interrupt signal at a time substantially independent of 
the amplitude and slope of the input signals. In 
accordance with the subject invention, each input 
signal is compared with an upper threshold level to 
determine if a valid signal has been detected. In 
addition, each input pulse is compared to a lower 
threshold level for timing purposes. The result of the 
comparison with the lower threshold level is delayed 
and supplied to a gate means with the output of the 
first comparison. The gate functions to produce an 
output signal when the results of both comparisons 
received are simultaneously positive thereby indicating 
the validity of the input pulse at a time independent 
 
 
of the amplitude of the pulse whereby the effects of 
jitter are reduced.
