Patent EP-0338591-A3 (EP)
Title: Nucleic acid extraction method
IPC: C12Q1/6888
Filed: 1989-04-21
Abstract: Nucleic acids are extracted from biological 
samples by pretreating the samples to release the 
nucleic acids and contaminating materials into an 
aqueous phase. Optionally, the samples may be 
extracted with an anionic detergent in an organic 
solvent prior to release of the nucleic acids. The 
aqueous phase is then combined with an organic phase in 
the presence of a cationic detergent capable of forming 
water insoluble complexes with the nucleic acids. 
Usually, a chelant will also be combined with the 
aqueous phase. The complexes are preferentially 
partitioned into the organic phase and are thus 
separated from the contaminating materials which remain 
in the aqueous phase. The nucleic acids may then be 
transferred back to a second aqueous phase by combining 
the organic phase with water in the presence of an 
inorganic salt selected to displace the detergent 
cation. After separation of the organic phase, the 
second aqueous phase containing the nucleic acids may 
be used for conventional hybridization testing.

Title: Lamp assembly utilizing shield and ceramic fiber mesh for containment
IPC: H01J61/50
Filed: 1989-10-02
Abstract: A double-enveloped lamp assembly includes a 
light-source capsule subject to burst on rare 
occasions, a light-transmissive shield 
substantially surrounding the light-source capsule 
for absorbing and dissipating a portion of the 
energy when the light-source capsule bursts, a mesh 
of substantially nonconducting fiber for 
reinforcing the shield, and a light-transmissive 
outer envelope. The mesh is fabricated of ceramic 
fibers having sufficient strength to reinforce the 
shield. Since the fibers are nonconducting, sodium 
migration is minimized. The ceramic fiber mesh is 
particularly useful for high wattage lamps where 
thick-walled outer envelopes are not practical.

Title: Verwendung eines Magnetkerns in einem Schnittstellen- Übertrager
IPC: H01F1/153
Filed: 1989-12-18
Abstract: Im neuen digitalen Kommunikationssystem ISDN erfolgt die 
Übertragung zwischen dem Netzabschluß ( 2 ) und den Endgeräten 
( 3 ) über die sogenannte S₀ - Schnittstelle durch 
Schnittstellenübertrager (6, 11). Da die Stromversorgung der 
Endgeräte zum Teil ebenfalls über diese Übertrager erfolgt, 
hat eine Stromunsymmetrie in den Leitungen (7, 8) bzw. (9, 
10) eine Vormagnetisierung der Übertrager zur Folge. Die 
ISDN-Anforderungen an die Übertrager müssen somit auch bei 
einer Gleichstromvormagnetisierung erfüllt werden. Kompakte 
Übertrager mit einfachem Wicklungsaufbau, die die 
ISDN-Anforderungen erfüllen, weisen als Magnetkernmaterial 
erfindungsgemäß eine amorphe Co-Basislegierung mit einer 
Permeabilität von mehr als 25 000 und weniger als 95 000 
auf. Vorzugsweise enthalten die Magnetkerne neben Co im 
wesentlichen Fe und Mn mit einem Gesamtgehalt von 3 bis 
8 Atom-% sowie Metalloide mit einem Anteil von 24 bis 
29 Atom-% und wahlweise bis zu 15 Atom-% Ni sowie bis zu 
1 Atom-% Mo, Cr und/oder Ni.

Patent EP-0328175-A3 (EP)
IPC: B60T17/18
Filed: 1989-01-25
Abstract: A brake source select system for selecting one of a plurality of sources of 
pressurized hydraulic fluid for use in actuating a brake system. The brake source 
select system (10) includes a primary, secondary and reserve source (20, 22 and 24) 
of pressurized hydraulic fluid connected in fluid communication respectively to a 
primary selector valve (32), a secondary selector valve (96) and a reserve selector 
valve (102). Pressurized hydraulic fluid from the primary source (20) is applied to 
deselect ports (94 and 100) on the secondary and reserve selector valves, causing 
those valves to block fluid flow from their associated sources to the brake system, 
so long as the primary source is operative. Upon failure of the primary source, 
pressurized fluid is no longer applied to the deselect port of the secondary 
selector valve, thereby enabling fluid flow through the valve, and causing 
pressurized hydraulic fluid from the secondary source to be applied to the deselect 
port (160) of the reserve selector valve and to a deselect port (164) of the primary 
selector valve, effectively blocking fluid flow through each of those valves. 
Should the secondary source fail, elimination of the pressurized fluid applied to 
the deselect port of the reserve selector valve enables it to conduct pressurized 
hydraulic fluid to the brake system, and applies the pressurized hydraulic fluid to 
the primary and secondary selector valve deselect ports, blocking fluid flow 
through those valves. Thus, failure of a higher priority source automatically 
results in selection of a next lower priority source to provide pressurized fluid to 
the brake system. In addition, a source of pressurized fluid associated with 
retraction of a landing gear is applied to a selection port (208) of the secondary 
selector valve, causing that valve to provide a source of pressurized hydraulic 
fluid to actuate the brakes, slowing the rotation of wheels prior to full retraction 
of the landing gear.

Patent EP-0365115-A3 (EP)
Title: Object identifier generator for distributed computer system
IPC: G06F15/16
Filed: 1989-07-19
Abstract: An identifier generator produces unique identifiers for objects in a distributed computer system by concatenating (i) the identifier of the node associated with the object - a unique space component; (ii) the current time read from an associated clock, adjusted such that no two identifiers created by the same generator have the same current time, regardless of the resolution of the associated clock - a unique time component; and (iii) a random name-sequence; and (iv) a (software/hardware) version number. The generator stores the time and the random name-sequence components. When the next identifier is generated, the generator compares the then current time with the stored time component. If the times are equal, the current time is adjusted and the adjusted time is used as the new identifier time component. If the current time is less than the stored time, the generator changes the stored random name-sequence component and uses it and the current time as identifier components. If the random name sequence component used in the previous identifier is lost, the generator generates a new random name sequence and uses the new sequence and the then current time as identifier components. If the time component used in the previous identifier is lost, the generator changes the random name-sequence is a predetermined manner and uses it and the then current time as identifier components.
