Patent EP-0356783-A3 (EP)
IPC: C23C2/12
Filed: 1989-08-10
Abstract: Continuous hot dip aluminum coated fertitic chromium alloy 
steel strip. Strip is cleaned by heating to a temperature no greater 
than about 650°C in a direct fired furnace. The cleaned strip is 
further heated in a protective atmosphere containing at least 95% 
by volume hydrogen, cooled in the protective hydrogen 
atmosphere to near or slightly above the melting point of an 
aluminum coating metal, and passed into a bath of the aluminum 
coating metal. The low direct fired furnace cleaning temperature 
and hydrogen protective atmosphere provides good wetting of a 
chromium alloy steel surface to prevent uncoated areas or pin 
holes in the aluminum coated layer.

Title: Method for welding relatively small parts
IPC: G02B6/42
Filed: 1989-10-05
Abstract: Laser welding of an outer sleeve 14 to an inner fiber ferrule 12 is 
expedited by, first, machining a thinned region 18 in the outer diameter of the sleeve. 
After the ferrule has been inserted in the sleeve, the thinned region permits the laser 
to fuse through the sleeve and melt part of the ferrule, as is required for laser welding 
of ferrule for the sleeve. The thinned region is preferably made by using a rotary 
cutter to cut an axially extending slot in the outer sleeve, which permits a succession 
of laser welds 21 in the axial direction in the slot. In a preferred embodiment, 
thinned regions 18, 19 are made on opposite sides of the outer sleeve, and laser 
welding is performed simultaneously on both sides of the sleeve so as to avoid 
distortions caused by thermal stress asymmetries.

IPC: H04L12/56
Filed: 1989-12-20
Abstract: A packet distribution network including a distributed 
arrangement for selecting packets based on the availability or 
unavailability of packet destinations is disclosed. A plurality of 
input units (108, 109, 110) receive and store packets before 
distribution. Each input unit also receives a sequence of addresses 
(via 129) representing packet destinations and a sequence of usage

unavailability of an associated one of the destination addresses. 
The sequence of addresses and the associated usage indicators are 
provided to the input units such that the address of each packet 
destination is contemporaneously received by only one input unit. 
Each input unit selects a stored packet based on the received 
destination addresses and associated usage indicators and marks 
previously available destinations unavailable to other input units 
by modifying the usage indicator associated with a packet 
destination for which a packet is selected.

Title: Variable optical fiber delay line
IPC: G02B6/00
Filed: 1990-03-27
Abstract: A variable delay line (10) has a first optical fiber 
(12) to transmit an optical signal and a plurality of second 
optical fibers (14) adapted to receive simultaneously the 
optical signal from the first fiber (12). Each second fiber 
(14) has a predetermined length (L i ), the length (L i ) of each 
second fiber (14) being different from each other second fiber 
(14). The predetermined length (L i ) determines the propagation 
delay of the optical signal along each second fiber (14). An 
opto-electronic switch (20) is made responsive to the optical 
energy on a selected one of the second fibers (14). The switch 
(20) detects the delayed optical energy and couples the delayed 
optical energy on an electrical analog thereof to a device. 
The selected second fiber (14) is chosen for the propagation 
delay associated therewith.

Title: Distribution device for a telecommunication installation
IPC: H05K7/14
Filed: 1990-07-13
Abstract: The distribution device has disc-shaped contact components (1) which are provided with two rows of connecting elements (2), projecting on the front side, for incoming and outgoing lines (e.g. 10). The connecting elements (2) are connected to contact springs (3) on the rear side which, for their part, are electrically connected via a protection connector (5), which can be pushed in at the rear from the side.

IPC: H01R12/04
Filed: 1990-03-27
Abstract: A low cost process for fabricating solder column intercon­

process includes the steps of filling an array of pin 
holes in a pin mold (14) with a lead/tin solder, which 
array of pin holes is in substantial registration with the 
array of conductive pads (12) on one side of a chip carri­
er (2); heating the lead/tin solder in the pin mold such 
that the solder becomes molten and coalesces with the 
array of conductive pads of the chip carrier, thereby 
forming an array of miniature pins (4) bonded to the array 
of conductive pads of the chip carrier; joining circuit 
components to the other side of the chip carrier; and 
reflowing an eutectic lead/tin solder paste screened to 
the corresponding array of conductive pads of a circuit 
board to bond the free ends of the array of miniature pins 
of the carrier to the corresponding array of conductive 
pads, thereby forming the solder column connections be­
tween the chip carrier and the circuit board. The process 
is suitable for mass production of reliable, high-density 
electrical inter-connections between a chip carrier and a 
supporting circuit board.
