Patent EP-0241238-A3 (EP)
IPC: G11B15/675
Filed: 1987-04-03
Abstract: A streaming tape drive having a cartridge loading appar­
atus (54) which locks a tape cartridge (14) into a fully loaded 
position yet does not resist motion of the cartridge (14) dur­
ing loading and unloading. To lock the cartridge (14) in the 
fully loaded position rollers (56) nest within cut out notches 
(28) on the side edges (24) of the cartridge (14). The rollers 
(56) are rotatably mounted on carrier levers (60) which in turn 
are pivotably secured to the tape drive housing (12). Rotation 
of the carrier levers (60) in one direction causes the rollers 
(56) to engage the cartridge (14), whereas rotation of the car­
rier levers (60) in the opposite direction causes disengage­
ment of the rollers (56). Means (74) are provided for manually 
rotating the carrier levers (60) so that the rollers (56) are dis­
engaged from the cartridge (14) during loading and unload­
ing of the cartridge (14).

Patent EP-0260839-A3 (EP)
IPC: H04B3/00
Filed: 1987-08-28
Abstract: A protection arrangement for a two-wire line, such as a 
telephone sunscriber line, includes a transformer having two primary 
windings and a secondary winding. The primary windings are 
connected in series with the wires of the line with phases such that 
common mode (longitudinal) currents on the line induce a current in 
the secondary winding, whereas loop currents do not. The induced 
current in the secondary winding is amplified and used to trigger a 
protection device, such as a triac or SCR and diode bridge 
arrangement, to short circuit the line for the duration of any 
excessive current thereon.

Title: Impact sheet for in-line injection pumps
IPC: F02M55/00
Filed: 1988-09-01
Abstract: In fuel injection pumps the pump chamber is discharged at the end of injection by the opening of an overflow aperture. Due to these overflow impacts cavitation occurs in the housing of the injection pump which can lead to detached metal particles which in turn cause damage to the injection system. According to the invention it is proposed to arrange an acutely angled baffle plate inside the discharge chamber whose acute opening angle is turned towards the overflow aperture. The invention can be used in the case of injection pumps, in particular in-line injection pumps. <IMAGE>

Title: New immunologically active synthetic peptides useful for preparing an antimalarial vaccine
IPC: C07K16/20
Filed: 1988-11-17
Abstract: Synthetic peptides consisting of at least two consecutive 
repeating units of the sequence (Ala-Asn-Asn-Pro) are powerful 
immunogens in experimental animals.

Patent EP-0345793-A3 (EP)
IPC: E04B1/94
Filed: 1989-06-08
Abstract: The invention relates to the inhibition of the propagation of a fire in a building along ventilation ducts. To this end, a lattice of highly heat-conductive material, such as expanded metal, is introduced into the cross-section of the ventilation duct and is able to conduct heat away to the walls of the ventilation duct and hence prevent or delay the breaking-through of the flame. Since such a lattice becomes soiled during the operation of the ventilation plant, it must be easy to exchange and clean. For this reason, it is advisable to introduce the filling in the form of expanded metal spheres laid loose on a strong intermediate level made from transverse struts or perforated sheets, etc.

Patent EP-0354763-A3 (EP)
IPC: G06T1/00
Filed: 1989-08-08
Abstract: A method and means is presented to estimate the 
contour of a body to compensate for attenuation in the 
production of a reconstructed image in fan beam 
computed tomographic systems having a detector system 
for taking a plurality of projections of a scanned body 
at a plurality of angles. The method and means defines 
a set of variable parameters representing an arbitrary 
ellipse and projects the arbitrary ellipse into fan 
beam projection space to determine the expected edges 
of the arbitrary ellipse at each angle in terms of the 
variable parameters. A series of fan beam projections 
is taken having sufficient information for 
reconstructing a cross-sectional image of the scanned 
body, and the fan beam coordinates of the apparent body 
edges in each of the projections are determined. The 
expected edges of the projected ellipse are fitted to 
the determined apparent body edge coordinates for each 
projection by iteratively optimizing all of the 
variable parameters of the arbitrary ellipse to 
determine a final set of parameters which defines an 
elliptical contour which best fits the scanned body. A 
cross sectional image of the body using the plurality 
of projections is then reconstructed and compensated by 
assigning attenuation values to the portion of the 
reconstructed image encompassed by the elliptical 
contour.

Patent EP-0360477-A3 (EP)
IPC: H01L21/8238
Filed: 1989-09-12
Abstract: An integrated circuit formed on a 
substrate (101) has field effect transistors formed in 
relatively lightly doped (i.e., high 
resistivity) epitaxial layer (113), typically in a "tub" (102,103) 
formed therein. Operating current for 
the transistors is provided at least in part 
through a metallic layer (100) on the back 
side of the substrate. Surprisingly, the 
conductivity is sufficiently high 
through the epitaxial layer and the substrate that the 
number of power supply bondpads on 
the front side may be reduced, or eliminated 
entirely in some cases. In addition, 
a reduction in power supply lead inductance is 
obtained, reducing ringing and ground bounce problems.
