Patent EP-0133046-A3 (EP)
IPC: C12R1/225
Filed: 1984-07-30
Abstract: A method of introducing a donor DNA into a strain 
belonging to the genus Lactobacillus, comprises preparing 
spheroplasts of the strain, encapsulating donor DNA within 
liposomes to obtain DNA-encapsulating-liposomes, and 
allowing the DNA-encapsulating-liposomes to fuse with the 
spheroplasts in the presence of a fusion inducing agent such 
as polyethylene glycol. The donor DNA may be provided in 
the form of recombinant DNA molecules prepared as a vector 
having inserted therein suitable phage DNA, plasmid DNA or 
heterogenic DNA retaining useful genetic information. Exam­
ples of the phage DNA include the DNA of the virulent phage 
J1 and the DNA of the temperate phage FSW selectively 
retained in the genus L. casei.
Patent EP-0152081-A3 (EP)
IPC: B23Q11/02
Filed: 1985-02-08
Abstract: A machining center in which the moment (M) exerted on 
a support base (21) and support table (28) during a machin­
ing operation is remarkably reduced. The machining appar­
atus includes a pair of guide rails (29,30) extending in the 
longitudinal direction (X) relative to the workpiece upon 
which the machining head (32,35) is slidably supported 
either directly or via a table. The rear one (30) of this pair of 
guide rails (29,30) is made higher than the other guide rail 
(29), thereby reducing the reaction forces exerted upon the 
upper surfaces of the guide rails (29,30), and hence the 
moment (M) exerted on the supporting base (21).

Title: Chair
IPC: A47C1/032
Filed: 1987-10-01
Abstract: The chair has a seat or seat portion equipped with a balance and its linkage structure has links fixed in articulated manner to a support arm and to which there is articulated a balance device in parallelogram-like manner. A slide is slidingly guided on the balance device and is connected by means of a thrust rod to an extension arm of the backrest-side link. The slide is also connected to one end of a spring element, the other end of which is supported on the balance device. The linkage structure is supported on the backrest by means of a backrest strut articulated to the slide. The seat and backrest portions of the chair frame can be constructed as a plastic shell with a knee-side bending joint and a further bending joint between the seat portion and the backrest portion. Due to the construction of the chair frame to incorporate a balance device, as least part of the forces exerted by the occupant or user of the chair can be absorbed by the balance device, so that the spring element can be made smaller and therefore less expensively, and there is also no need to adjust or adapt the spring element to different body weights of the users of the chair.

Abstract: A positive-positioning knob assembly comprises a knob 
body (20) having a substantially hollow interior 
portion and a pinion member (34) non-rotatably 
mounted relative to a shaft (16) to be rotated by the 
knob assembly. Cooperating selectively 
interengageable and disengageable locking members 
(40, 42) are located on the pinion member (34) and 
the hollow body (20) interior respectively for 
alternatively permitting the body (20) to rotate 
freely of the pinion member (34) when the locking 
members (40, 42) are in a disengaged condition, and 
for locking the body (20) non-rotatably relative to 
the pinion (34) when the locking members (40, 42) are 
in an engaged condition. A resilient biasing member 
(50) normally holds the locking members (40, 42) in 
the engaged condition to prevent rotation of the knob 
body (20); however, the resilient biasing member (50) 
is resiliently deformable for permitting the locking 
members (40, 42) to move to the disengaged condition 
to permit rotation of the knob body (20).

Abstract: The present invention provides a contextual editor for an 
expert system. The editor leads the operator through a 
series of screens which designate classes of information, 
logical nodes, and the interrelation of the nodes. The 
screens are so arranged that they prevent the operator 
from providing classes or nodes with logically insufficient 
information. At the end of each definition the 
screen automatically shows a logical tree which graphically 
illustrates the logical interconnection between the 
nodes.  
     The editor provided by the present invention provides the 
knowledge base developer with a guided knowledge entry 
system that modifies its behavior based on the context of 
the knowledge structures being entered. This approach not 
only facilitates the creation of the rules base knowledge, 
but also frequently prevents the user from entering 
invalid values or logic structures. Also, the guided 
editing approach allows the developer to learn and use the 
system much more quickly, thus becoming productive much 
sooner.

The liquid fraction 19 is fed back into the second rectification stage. Another fraction 22 is removed from the raw argon column above the bottom thereof and is separated in a high-purity oxygen column 23 to produce a high-purity oxygen fraction 25, 26 and a lighter residual fraction 24. An additional nitrogen-rich fraction is removed from the head of the first rectification stage and separated in a high-purity nitrogen column 31 producing a bottom liquid fraction 29, which is fed back to the head of the first rectification stage, and a residual gas fraction 33. A high-purity nitrogen fraction 34 is removed at a point several plates below the head of the first rectification stage.
