Patent EP-0174125-A3 (EP)
Title: Digital data receiver
Inventor: YEN JUI L
IPC: H04L27/38
Filed: 1985-08-16
Abstract: A data receiving system for digital data communication 
is described which uses asynchronous sampling and lan­
guage interpolation or prolate spheroidal function on the 
received signal. A received analogue signal is first asynchro­
nously sampled (22), digitised (26), stored in memory (28) 
and then processed using interpolation techniques to recov­
er the correct symbol timing of the symbols in the digitised 
data. The minimum sampling rate commensurate with 
channel band width is used. The correct symbol timing is 
continuously adjusted within certain predetermined limits of 
the interpolation interval using a "jumping" algorithm which 
permits continuous symbol recovery. The recovered sym­
bols are then equalised (40) to compensate for distortion and 
decoded (44) to give the originally encoded data. When 
bursts of data are being transmitted the data stored in 
memory (28) is replayed to ensure that all data in the data 
burst is used for communication and that there is no 
transmission overhead requiring extra symbols for synchro­
nisation. In one embodiment the received signal is used to 
generate real and imaginary components (32,34) which are 
then subjected to interpolation (36,38) and, the interpolation 
is controlled using a digital filter and algorithm which 
optimises filter coefficients to recover the symbol timing.

IPC: B32B7/02
Filed: 1986-10-14
Abstract: A method of forming a laminated fabric which 
includes an inner air-laid, batt-like material (12) 
comprising randomly arrayed fibers of carbon and a 
thermoplastic copolyvinyl such as Vinyon is manufactured 
by feeding the outer shell layers (16, 18) on opposite 
sides of the batt (12) through an ultrasonic treatment 
station (28) where ultrasonic energy is applied to the 
material. The sonic horn (32) engages one side of the 
laminate, while a patterned anvil roller (30) from which 
pins (40) extend radially in a predetermined pattern 
engages the other side of the material being treated. 
Accordingly, ultrasonic energy applied by the ultrasonic 
horn (32) is concentrated at the pins (40), which fuses 
the thermoplastic fibers in the batt (12) at the places 
where the pins (40) engage. Since the shell fabrics (16, 
18) are also thermoplastic, the columns (44) formed 
through the batt (12) due to their engagement by the pins 
(40) and the ultrasonic energy are also fused to the 
outer shell fabrics (16, 18). Accordingly, a laminate is 
produced in which columns (44) extend through the batt to 
unite the outer shell fabrics (16, 18) with each other 
and with the batt (12).

Patent EP-0225009-A3 (EP)
IPC: G01N15/02
Filed: 1986-09-26
Abstract: The invention comprises apparatus capable of un­
ambiguous determination of the length and diameter of fib­
rous particles, especially asbestos fibres, based on near-­
forward scattering of light by fibres aligned within a 
hydrodynamically focused gas flow region (22). Three port­
ions of scattered light are detected, two portions per­
pendicular to the fibre axis and one aligned with it, from 
which length and diameter can be independently deter­
mined. This independence is achieved by allowing only selec­
ted parts of the light scattered within certain selected ranges 
of angles to reach each detector (31,37 and 41). A two-­
detector instrument capable of accurate determination of 
fibre diameter is also described.

Patent EP-0247788-A3 (EP)
IPC: H04N7/18
Filed: 1987-05-20
Abstract: There is disclosed a system for storing an image 
of an object to be identified and for retrieving the stored 
image of the object for displaying the same on a display 
screen. The system includes electronic scanning means for 
scanning the object on a line-to-line basis to provide a 
analog signal for each line indicative of the information 
content of said object. The analog information is converted 
by a digitizer into pixels which define a matrix which 
matrix determines the information content for each line. A 
window area is generated which area encompasses a 
predetermined area within a larger display area. The window 
area is used to generate and to respond to a first set of 
digital information which information is derived from the 
matrix pixels. This first set of digital information is such 
that the window area contains a limited number of pixels 
plus a limited number of lines, each of which is generated 
when the window area is scanned. A critical identification 
area is defined by the apparatus which critical 
identification area is determined by the common 
characteristics areas associated with the object to be 
scanned. In an image of a person's face, the area consists 
of a "T" zone which encompasses the eyes, nose and mouth 
 
 
area. In this critical identification area, information is 
generated or employed which employs pixels that were skipped 
during the scanning of the window area. In this manner the 
critical identification area contains more detailed 
information to enable one to thereby authenticate the 
regenerated image from the first and second sets of digital 
data to thereby enable one to positively identify one person 
as compared to another person. The technique thus described 
provides a video compression of such data whereby the 
resultant digital information is capable of being stored on 
a very limited medium such as a magnetic stripe associated 
with a credit card.

Title: Fibre-optic detector for oils and solvents
IPC: G01M3/04
Filed: 1988-03-08
Abstract: In the present invention is described a liquid detector (10) 
employing fibre optics, by which can be detected the presence e.g. 
of oils and various solvents. The means is internally safe because 
the optic fibre (13) is an insulator and it may therefore be used 
to monitor liquids involving fire or explosion hazard. The means 
may be used to detect leakage when storing oils and solvents 
because it reacts most rapidly with these liquids. The detector 
(10) makes use of the capillarity of the sensing pick-up (14), the 
optical reflection coefficient of the pick-up material changing as 
it comes into contact with the liquid (16) to be detected.

Title: Artificial pumice stone
IPC: C04B32/00
Filed: 1988-06-27
Abstract: An artificial pumice stone is described. These bodies are 
relatively light-weight, containing massive parts and 
gaseous parts, and are abrasive. Following the present 
description, the material of these bodies is cellular glass 
which is obtained from a mixture of glass powder and 
cellulating agent. This mixture is heated for melting and 
cellulating and is cooled down afterwards. The desired 
relatively small cellular glass bodies are obtained by 
dosing small parts of the mixture before the heating, or by 
reducing bigger cellular glass bodies into smaller cellular 
glass bodies preferably by a sudden change of temperature. 
These cellular glass bodies receive an abrasive treatment on 
their surface, cleaning the surface generally eliminating 
the glass crust that covers the cells and rounding the 
edges, where the abrasive elements are principally the 
cellular glass bodies themselves. The final size of the 
abrasive treated bodies is between 1 and 30 centimetres and 
the density between 0.2 and 2.0 grams per cubic centimetre. 
The cells of these bodies can be filled with liquids and 
preferably by the vacuum process.

Title: Monitoring the efficiency of liquid pumps
IPC: G01M99/00
Filed: 1988-10-07
Abstract: A method of monitoring the efficiency of a liquid pump (10) uses the temperature drop across the pump (10). Closely matching thermocouple junctions (13,14) of copper/constantan from the same respective alloy batches are bonded to suction and discharge conduits (11,12) using a low-viscosity "super-glue" to attain close thermal coupling. Each thermocouple junction (13,14) is thermally insulated by covering with a silicone rubber diaphragm (18) the rim of which is attached to the conduit by adhesive to enclose the junction in an air-tight pocket (17). Further thermal insulating and protective boxes (19) enclose the diaphragms (18). The thermocouple output is connected by copper wire to a thermally insulated voltage measuring instrument (16). The method produces useful accuracy for relatively low cost.
