Patent EP-0244923-A3 (EP)
IPC: H02K3/18
Filed: 1987-01-21
Abstract: A method for flattening round wire and 
winding a main field coil with the round wire in­
cludes the steps of feeding a length of round wire 
through a pair of non-driven pinch rollers to impart 
a predetermined degree of flattening such that as the 
wire is wrapped around the rotating main field, it 
can be laid into the trough in precision manner with 
successive turns vertically aligned. The flattened 
round wire is laid into the trough with the flat of 
the wire parallel to the bottom of the trough to in­
crease the stability of the winding, and to facili­
tate the vertical alignment of successive layers.
Patent EP-0241190-A3 (EP)
IPC: G03F1/72
Filed: 1987-03-30
Abstract: The invention relates to visible-laser deposition reactions 
of metal containing oxyhalide and carbonyl vapors, such as, 
chromyl chloride vapor, CrO₂Cl₂, or cobalt carbonyl, 
Co₂(CO)₈, for direct writing of metal containing opaque pat­
terns on various substrates (S i , S i O₂, GaAs and glass). De­
position at low laser power is by photolyses of adsorbed reac­
tant molecules. Higher powers initiate deposition 
photochemically and continue it with a combined photolytic/­
pyrolytic reaction, simultaneously inducing a solid-phase 
conversion of the deposited film. Mixed Cr₂O₃/CrO₂ or cobalt 
thin films of 1-nanometer to several-micrometer thickness, as 
well as 1-millimeter-long single crystals of Cr₂O₃ or cobalt, 
can be grown with this process, the former at rates up to 3 
µm/s. Thin chromium oxide films produced in this manner 
are strongly ferromagnetic.

quantity from the semiconductor laser (l08).
Patent EP-0259112-A3 (EP)
IPC: E05B65/10
Filed: 1987-08-28
Abstract: An electrically operated exit device comprises a 
low powered dogging assembly (250) for a pushbar (22) and 
an electrical actuator for a latch bolt (16). A latching 
bracket (254) is attached to the pushbar for movement 
inwardly and outwardly along a path. A dogging plate 
(252) of the dogging assembly is pivotally moveable 
between a retracted position out of the path of the 
latching element and an extended position in the path of 
the latching element. The dogging plate is spring biased 
(214 b ) toward the extended position and has a protruding 
shoulder (271). When the dogging plate is extended and 
the pushbar moved inward manually, the latching bracket 
strikes the dogging plate, retracts it slightly against 
the force of the spring bias and then continues slightly 
beyond the shoulder of the dogging plate. Then, the 
dogging plate again extends fully under the influence of 
the spring bias such that a bearing surface (267) on the 
far side of the shoulder catches the latching bracket and 
thereby dogs the pushbar.

Title: Apparatus for measuring the peak voltage applied to a radiation source
IPC: H05G1/26
Filed: 1989-03-08
Abstract: Apparatus is provided for use in detecting the peak 
voltage applied to a radiation source operating at an 
unknown input voltage. The apparatus includes a set of 
radiation absorbing filters including a first filter which 
includes a first element that exhibits a known K-absorption 
edge and a second filter constructed of a second element so 
that the filters exhibit essentially the same radiation 
absorption characteristics below the K-absorption edge of 
the first filter. The filters are adapted to be positioned 
so as to be irradiated by the radiation source so that the 
radiation impinges upon a surface of each filter and is 
partially absorbed as it passes therethrough so as to exit 
therefrom as attenuated radiation. A detector, such as 
X-ray film or a pair of photodiodes, is positioned for 
receiving the attenuated radiation passed by the first and 
second filters and provides an output indication when the 
radiation passed by the filters is differently attenuated. 
This is indicative that the known K-absorption edge of the 
first filter has been exceeded, thereby providing an 
indication as to the magnitude of the voltage applied to 
the radiation source.

Title: Method and apparatus for memory routing scheme
IPC: G06F12/06
Filed: 1989-08-24
Abstract: A memory routing scheme for a computer system having M 
processors (P0 ... P5) and N memories is described. M 
processors are coupled through a randomizer (23) to a routing 
network (10), such as a crossbar. The crossbar is coupled to N 
memories (MEM 0 ... 5). When a memory address is specified by 
a processor, it is acted on by the randomizer and a routed 
address is given to the memory. The memory having the routed 
address is coupled to the processor for the access. By 
utilizing a random routing scheme, the memories are not 
optimized for any one particular access mode, but present the 
same look to the processors regardless of the access mode. The 
average number of collisions in this scheme is a function of 
the number of memories, number of processors and number of 
access ports. In one embodiment, a hashing table is utilized 
for the assignment of the routing address to the memories. 
Alternatively, a randomizing function is utilized to generate 
a routing address.
