Patent EP-0292325-A3 (EP)
IPC: H01M50/491
Filed: 1988-05-20
Abstract: A new type of polymeric microporous membrane has 
been synthesized which is distinguished by a highly-branched 
porespace morphology that is continuous and triply-periodic, 
and thus very precisely controlled and easily characterized. 
The membrane consists of a polymeric matrix containing 
pores of diameter on the order of 10 nm connected into a 
continuous pore network exhibiting long-range 
three-dimensional order. This long-range order is evidenced 
in small-angle X-ray scattering (SAXS) experiments by Bragg 
reflections that index to a triply-periodic space group, as 
well as in electron micrographs that match predictions from 
a theoretical model of the same space group and lattice 
parameter. The membrane combines three important features 
that have not been present simultaneously in any prior art 
membrane having pore diameters between 2 nm and 1 micron. 
First, the pores are identical in size and shape to a very 
high degree, and their size can be controlled in the 
synthesis. Second, the porespace is characterized by 
intricate branching and reconnections, with at least three 
pore throats meeting at a given pore body, this number (the 
coordination number) being the same for each pore body, and 
the porespace is isotropic in the cases where the space 
group is cubic. These two features allow accurately 
controlled sieving on the basis of particle size and shape, 
 
 
and provide highly accessible and precisely shaped pore 
bodies and surfaces for other applications such as 
catalysis, ion exchange, and the preparation of metal 
microstructures. And third, the membrane has a high 
porosity -- approximately 90% -- so that high rates of 
throughput can be reached. In addition, the membrane can be 
produced from certain microstructured fluid phases that are 
thermodynamic equilibrium states, so that it can be produced 
inexpensively and reliably.

Title: Method of apparatus for expanding and sealing a sleeve into a surrounding tube
IPC: B21D39/20
Filed: 1988-07-22
Abstract: A method and apparatus for locating a sleeve within a 
surrounding tube and pressure-tightly sealing the sleeve 
within the tube to repair leaks in the tube. The sealing 
method utilizes dual elongated pressurizable tools. The 
first tool device includes a housing having a 
reduced-diameter forward extension portion attached to a 
front cylinder, and containing a rear piston. The front 
cylinder, is attached to a collet having multiple radially 
expandable fingers and contains a front piston attached to a 
tapered mandrel which is axially movable within the fingers, 
and has a forward tapered nose portion to facilitate 
inserting the tool into a tube. The rear piston is attached 
to the front piston by an elongated rod. By pressurizing 
the tool front piston by a hydraulic fluid pressurizing 
unit, the mandrel is forced forward through the collet 
fingers to expand the fingers against the sleeve and thereby 
expand the sleeve tightly into the tube to form the seal 
joint. After withdrawing the tool from the tube, the tool 
rear piston is similarly pressurized to retract the front 
piston and attached mandrel back through the collet 
expandable fingers to reset the tool prior to its further 
use. The second tool includes a housing containing an 
axially movable piston and a forward reduced diameter 
portion and having an elastic expander unit for inserting 
into the sleeve and tube in a tubesheet. The expander unit 
consists of at least two elastic rings composed of an 
elastomer material and each having a chamfer provided at the 
outer edge of the unit forward and rear faces. By 
pressurizing a port at the housing front end, the piston is 
 
 
moved rearwardly to axially compress and expand the expander 
rings radially outwardly sufficiently to expand the sleeve 
firmly into the tube and provide a pressure-tight seal 
therebetween. Following such expansion of the sleeve, the 
piston is pressurized and moved forward to release the 
compression on the expander unit rings, so that the tool can 
be easily withdrawn from the expanded sleeve and tube and 
inserted into another sleeve and tube for repeated usage.

Title: Spectroscopes
IPC: G01J3/443
Filed: 1989-05-22
Abstract: A compact spectroscope, particularly a 
sprectrofluoroscope or a microspectroscope, applicable 
for spectrophotometry of very slight light emission 
having a high visibility, overcoming the defects of the

aperture and a focus coincident with the source, a 
transmission type diffraction grating (G,55) and a

Patent EP-0352934-A3 (EP)
Title: Insertion and removal of a circuit device into a bus network
IPC: G06F1/18
Filed: 1989-07-11
Abstract: A circuit device 2 (e.g. mounted on a printed 
circuit board) is connected to data network, to which 
network are also connected a plurality of other circuit 
devices 2 under power. On removal of such a circuit 
device 2, the output driver 21 connecting the circuit 
components 28,29 of the output device 2 to the 
communications bus 5 of the bus network is first 
disconnected from power, and only when its disconnection 
is stable is the circuit device 2 withdrawn. A control 
device device 20 of the circuit device 2 is connected to 
the control bus 4 of the data network, and before power 
is disconnected from the output driver 21, the control 
device 20 signals to the network so as to prevent other 
circuit devices 2 connected to the network from 
signalling on the network. Effectively, the circuit 
device 2 to be removed "occupies" the bus. This 
occupation is maintained until the disconnection of the 
ouput driver 21 is stable, and then the circuit device 2 
can be removed from the network. Similarly, on 
insertion, the network is first occupied before power is 
connected to the output driver 21. In this way, it 
 
 
becomes possible to prevent faults due to mis-signalling 
between the other circuit devices connected to the 
network when one circuit device is inserted or removed.

cylinder (70) including an integral tubular member (112). A distribution 
disc (80) is coupled to the motor cylinder (70) at one end of the tubular 
portion and has oil passages (81,82) communicating with the hydraulic

a preload to abut an axial end face of the fixed seal member (115) 
against an axial end face of the rotatable seal member (116) and a 
preload to abut the end face of the distribution ring (92) against the 
distribution disc (180).

Title: Improved telecommunications database accessing method
IPC: H04Q3/00
Filed: 1989-12-13
Abstract: Method and apparatus for reducing call setup time for calls to Advanced 
800 customers by eliminating one database query. (Toll charges for 800 calls are 
paid by the called customer.) In the prior art, a call to an Advanced 800 customer 
required accessing a Basic 800 database, then, using data obtained therefrom, 
accessing an Advanced 800 database. In accordance with this invention, a table of 
the most frequently called Advanced 800 numbers and the corresponding data 
normally obtained from the Basic 800 database is dynamically maintained in each 
toll switching system. When an 800 call is received at a toll switching system, the 
table is examined to see if the Advanced 800 service accessing data is stored therein. 
If so, the advanced 800 database is directly accessed without first accessing the Basic 
800 database; ifnot, the call is processed as in the prior art, plus updating the table if 
the call is to an Advanced 800 customer. Advantageously, such an arrangement 
reduces call setup time to frequently called Advanced 800 customers by about 1.5 
seconds.

mounted on the board and at least one of the ground 
layers (2) and power supply layer (3) are connected to
