Patent EP-0222285-A3 (EP)
Title: Method and apparatus for making a corrugated tube by helically winding a thin corrugated strip, preferably a steel strip
IPC: F16L11/16
Filed: 1986-11-03
Abstract: In this method, at least one corrugation of the allocated strip is inserted into a corrugation of the wound strip produced beforehand, and at least one corrugation of the corrugations of the wound strip lying one inside the other is joined by pressing together. To obtain a simple and gas-tight, flexible corrugated tube which is inexpensive to produce, first of all the corrugation, to be pressed flat, of the incoming strip is preformed roughly in a trough shape in cross-section with a flat corrugation apex and roughly straight corrugation flanks slightly inclined to the outside, the corrugation, to be pressed flat, of the interlocked wound strip is then deformed in an omega shape in cross-section, and the corrugation apex and the corrugation flanks are in each case pressed together flat, the adjacent margins of the corrugation flanks pressed flat being at a distance from one another, and finally the corrugation flanks pressed flat are alternately pressed together with the corrugation apex in a point-like manner at a distance apart. <IMAGE>

Patent EP-0204562-A3 (EP)
Title: Transparent photovoltaic module
IPC: H01L31/0224
Filed: 1986-06-04
Abstract: A thin film photovoltaic module has transparent elec­
trodes on front and back surfaces of a semiconductive layer. In 
one embodiment, both transparent electrodes pass light to 
the semiconductive layer for photovoltaic purposes. In 
another embodiment, the back electrode passes light which 
enters through the front electrode and is not absorbed by the 
semiconductive layer, so that the module is selectively trans­
parent to the unabsorbed light. The spectral makeup of the 
transmitted light is controlled by controlling the optical char­
acteristics of the layers of the module. The index of refraction 
of the back electrode is a primary source of transmission 
control along with the refractive index of the front electrode 
and the thickness of the semiconductive layer itself. Light 
transmitted by the module can be used for nonphotovoltaic 
purposes, such as illuminating the interior of a vehicle or 
dwelling, or may be directed back into the semiconductive 
layer by a reflective surface behind the back electrode.

Title: Implantable catheter device
IPC: A61M39/00
Filed: 1987-07-11
Abstract: The implantable catheter device has a capsule (10) with a perforatable upper wall (15). A catheter (11) leads into a cavity (12) in the capsule (10). The catheter (11) is fixed to the capsule (10) by means of an elastomeric clamping piece (30), which is arranged in the inside of a connection piece (22). The connection piece (22) has an internal thread (23) in which an external thread of a thrust piece (26) engages. By turning the thrust piece (26), the clamping piece (30) is deformed, in order to press against the periphery of the catheter and fix the latter and seal it off relative to the capsule (10). The lateral dimensions of the capsule (10) are not increased by the connection piece (22). The catheter coupling can be easily tightened and released, and it affords satisfactory safety against the catheter being pulled out. <IMAGE>

Patent EP-0242023-A3 (EP)
IPC: B23K10/00
Filed: 1987-02-12
Abstract: An electrode (54) in an arc chamber (52) is attached at 
its inner end to an electrode support (68) and, at its distal 
end has an insert (60) opposed to a plasma outlet (42). The 
support (68) and electrode (54) are surrounded by a cylin­
drical insulator (80). The distal end of the support (68) fits 
closely within the insulator and partitions the arc chamber 
(52) from an inner annular chamber (94). Gas flows through 
a passage (70) within the support (68), through bores (76, 
78) to the chamber (94) and then through bores (100) 
through the insulator to an outer annular chamber (96). A 
proportion of the gas leaves this chamber through bores 
(98) to flow between the torch tip (40) and a diffuser (14) as 
secondary gas. Another proportion flows back through the 
insulator via passages (102, 104) adjacent the inner end of 
the electrode, to provide the primary gas. An axial passage 
(56, 58) extends from the inner end of the electrode (54) al­
most up to or right up to the insert (60) so that when, or 
shortly after, the insert has burnt away, gas will blow out 
through the distal end of the electrode.

the assay procedures at an appropriate interval prior 
to analysis using a labelled or tagged monoclonal 
antibody specific to a TdT epitope. The casein util­
ized successfully was obtained from a large variety of 
sources and includes the use of a non-fat milk product.

Abstract: A transmitter (10) for an alignment system in which 
a field (14) of electromagnetic radiation is propagated 
in a non-planar reference cone is disclosed. The 
transmitter (10) includes a chassis (16) with a source 
(27) fixed to the chassis (16) for providing a beam of 
electromagnetic radiation and an optical deflector (102, 
102′, 171, 182, 198, 226, 235, 260 or 277) which 
converges toward the source reflects the beam into an 
omni-directional cone of radiation (14). A flexible 
support (105, 105′, 105″, 170, 173, 184, 200, 228, 237 
or 267) having an omni-directional stiffness supports 
the optical deflector (102, 102′, 171, 182, 198, 226, 
235, 260 or 277) in the beam to reflect the reference 
field (14) in a level orientation when the chassis (16) 
is level. An angular error in the orientation of the 
chassis (16) from level results in the optical deflector 
(102, 102′, 171, 182, 198, 226, 235, 260 or 277) 
deviating from the aligned position to maintain the 
reference field (14) in the level orientation. Damping 
of the deflector (102, 102′, 171, 182, 198, 226, 235, 
260 or 277) is also provided for and sensors (132, 136, 
240, 241 or 242) detect when the angular error of the 
chassis (16) has exceeded an allowable amount.

Title: A process for growing silicon-on-insulator wafers
IPC: H01L27/00
Filed: 1988-05-13
Abstract: A process for growing silicon-on-insulator 
wafers in which complete isolation of the grown silicon 
from the substrate silicon by an intermediate oxide 
layer is obtained. A first epitaxial lateral 
overgrowth technique is used to grow a continuous layer 
of silicon through seed holes in a patterned oxide 
layer overlying the silicon substrate. Then the 
silicon layer (16) is etched to expose the seed holes 
which are then oxidized to make the oxide layer (12) 
aperture-free. This is followed by a second epitaxial 
lateral overgrowth step to replace the silicon etched 
in the silicon layer (16) to make a merged, 
substantially planar layer (28).
