Title: Recombinant interleukin-2 hybrid proteins
IPC: A61P37/00
Filed: 1989-11-09
Abstract: Production of recombinant human interleukin-2 (IL-2) 
fusion proteins can be substantially enhanced by utilizing a 
vector construction capable of expressing the hybrid protein 
at high levels. Additionally, the resulting protein can be 
purified with high yield employing a receptor-affinity 
column. A further advantage of the present vector 
construction is that the IL-2 expressed has a more natural 
sequence than the product provided by prior known expression 
systems for producing IL-2 hybrid molecules. In a specific 
embodiment of the invention, a fusion protein of IL-2 and 
Pseudomonas exotoxin is expressed at high levels in E. coli 
and purified to homogeneity with excellent recoveries and 
the desired high biological activity.

Patent EP-0348198-A3 (EP)
Title: Method of magneto-optically recording and erasing information and magneto-optical information storage medium for carrying out the method
IPC: G11B11/105
Filed: 1989-06-22
Abstract: A method of magneto-optically recording and erasing 
information which comprises irradiating pulse-like laser 
beam onto a magneto-optical information storage medium 
including recording and bias layers which has 
perpendicular magnetic anisotropy and which are stacked 
one upon the other to apply coupling interaction which 
is mainly magnetostatic interaction to each other, and 
magnetization-reversing temperature of the bias layer 
being higher than that of the recording layer. 
When the recording laser beam is irradiated onto the 
medium, the beam-irradiated portion of the medium is 
heated to form a reversed magnetic domain in the bias 
layer, magnetization of the recording layer is 
directed in a perpendicular direction by first leakage 
magnetic field applied to the recording layer when 
beam-irradiated portion is then cooled, and magnetiza­
tion of the bias layer is directed in same direction 
as that under initial state by second leakage magnetic 
field, applied to the bias layer. When the erasing 
laser beam is irradiated onto the medium, the beam-­
irradiated portion of the medium is heated to the 
magnetization-reversing temperature of the recording 
layer, and due to third leakage magnetic field 
applied to the recording layer at this time, the 
direction of magnetization of the recording layer is 
reversed.

Abstract: A shield device for use in sheathing a hypodermic needle (11) includes a pair of flap members (26, 27) which are hinged to a central elongate narrow plate (25) within which an open mouth (15) of the sheath is defined. The flap members (26, 27) are hinged on either side of the central plate (25) so that they can move from a retracted position lying parallel and on respective sides of the central sheath (13) to a deployed position in which they form with the central plate (25) a protective shield to hide fingers of the user from pricking as the needle (11) is inserted into sheath (13). The flap members (26, 27) are retained in the retracted position by a simple latching arrangement (40, 41, 43) which is released by compression of the flap members (26, 27). The sheath (13) and shield can be packaged as a disposable item in conventional manner with the disposable needle (11) and needle base (10) and can be used without modifying traditional handling techniques.

Abstract: Modems, data service units (109-111), application modules (108, 
112, 114, 115) and other data communication devices (102-106), installed in 
a common equipment cabinet, are interconnected by way of a time division 
multiplexed bus (RB, WB, TSA, TYPE). Time slots assigned to the various 
devices recur at a number of regularly-spaced access periods across each 
time division multiplex frame. The rate at which the access periods occur 
and the total number of access periods that make up each frame are chosen 
in such a way as to accomodate a mix of devices having respective bus 
access rates wherein there is at least one pair of rates for which neither rate 
of the pair is a multiple of the other. The process of allocating access 
periods to the time slots is carried out using a known lemma to identify 
linear Diophantine equation solutions.

Abstract: According to a method of detecting an acoustic 
signal, first and second sound receiving units are located 
at substantially the same position and are used to output 
signals having different target signal power to noise power

the given period is discriminated. The first sound 
receiving unit is an adaptive microphone array capable of 
controlling directivity characteristics in correspondence 
with a noise position.

Title: Device for automatic taking-out of articles from a transporting track
IPC: B65G47/88
Filed: 1990-05-18
Abstract: A device is disclosed for automatic taking-out of articles, in particular of containers from a roller conveyor. The device contains a pivotable rocker which, at its discharge end, carries a stop device for the containers situated on the roller conveyor. Arranged at the other end of the rocker is an overrun device which, in the unpivoted state of the rocker, lies under the conveying plane of the roller conveyor. As a result of the pivoting of the rocker, the stop device is lowered and the front container can be removed from the roller conveyor, while the subsequent container can be prevented from further movement by the overrun device. After the removal of the container, the rocker pivots back into the initial position and the subsequent container is conveyed on to the stop device at the end of the roller conveyor. <IMAGE>
