Patent EP-0454315-A3 (EP)
Title: An assay tray assembly
IPC: B01L3/00
Filed: 1991-04-08
Abstract: An assay tray assembly and an assay tray primarily for chromatographic analysis has a plastics moulded test tray 1 mounted on a plastics moulded collection tray 72. The test tray has a spaced array of chambers 3 disposed as per a microtiter plate. Each chamber has a bottom outlet port 5 formed by a flange 8 which retains within the chamber a chromatographic medium to which test liquid deposited in the chamber is to be subjected for the percolate or eluate liquid to emerge from the respective outlet ports. The collection tray 72 has a spaced array of wells 16 disposed as per a microtiter plate to correspond with the chambers 3 and the tray 1 is mounted on the tray 72 for each chamber to communicate with a corresponding well 16. Each chamber 3 has a tubular spigot part 12 which extends into the respective well 16 to alleviate cross contamination of the liquid derived from the outlet ports 5. The depth of entry of the tubular spigots 12 into their respective wells 16 is restricted by abutment between the bottom of the test tray with the top of the collection tray. The volume of each well 16 beneath the tubular spigot it receives is adequate to accommodate all of the eluate or percolate derived from the chamber 3 with which it communicates to alleviate liquid on the spigot parts from dripping into wells with which those tubular spigots are not associated (and thereby cause cross contamination) when the trays are separated for analysis of the percolate or eluate. <IMAGE>
Patent EP-0502401-A3 (EP)
IPC: H01J37/08
Filed: 1992-02-24
Abstract: A field emission source is used in conjunction with a 
three element asymmetric lens system to provide an 
electron gun having greater magnitude beam currents 
focused on a smaller spot size than has been previously 
possible for intermediate energy beams. The three element 
asymmetric lens system has a lower spherical aberration 
than prior art electrostatic guns and a very low chromatic 
aberration coefficient, enabling precise focusing of beams 
with large currents and energy spreads. The electron gun 
produces high current densities in beams focused on small 
spot areas, despite the relatively large acceptance angle 
and energy spread of the source beams.

Title: Manufacturing of multi-layer preforms with scrap PET.
Inventor: TEVLIN JOHN
IPC: B29C45/78
Filed: 1994-11-03
Abstract: The technical field of the invention are the moulding machines, particularly the inner part (core pin) of such moulding machines for manufacturing of thermoplastic preforms, which are later on stretch-blown to containers such as PET-bottles. The invention relates to preforms having a multi-layer structure and incorporating a recycled inner layer, embedded into two layers of virgin material being on the outside and the inside of said preform. The core pin is designed by the invention such that the inner layer of the preform has a minimum thickness at their bottom area and that the minimum thickness is considerably larger than that in a layer known from prior art. The increase of layer-thickness is achieved by designing the core (2) in its front end portion (3a,3b) in an unround fashion. Possible designs of unround front ends are a flat (3b) or a shallow dimple (3a). With such design of the core pin the invention assures that the middle recycled layer does not reach the inner surface of the preform to give the preform - although recycled thermoplasts are used - food-compatibility. <IMAGE>
Patent EP-0697587-A3 (EP)
Inventor: LEDEEN HOWARD L
IPC: F17D5/06
Filed: 1995-08-18
Abstract: The present invention is a system for locating release of
fluid in a pipeline. The system comprises means or mechanism for
detecting a pressure wave within the fluid indicative of a release
of fluid from the pipeline, such as a leak or an unauthorized
offtake. The system also comprises means or mechanism for
determining the location of the fluid release by creating a test
pressure wave within the fluid after the detected pressure wave.
The fluid can be gas or oil but is not limited thereto in that the
system will work with any fluid in a pipeline. Preferably, the
location determining means or mechanism comprises a mechanism for
creating a test pressure wave within the fluid in the pipeline and
a mechanism for detecting a reflection of the test pressure wave.
The reflection detecting mechanism and the original pressure wave
sensing means or mechanism can both use a pressure transducer which
is in communication with signal processing and control means or
mechanism, such as a computer. Pressure signals from the pressure
transducer are fed into the computer where they are processed and
analyzed. The computer can include a video display for displaying
the pressure signals and a keyboard for interacting with the
computer. Digital filtering techniques permit sensitive detection
with low false alarm rate. The present invention is also a system
for mapping a pipeline. The system comprises a mechanism for
creating a test pressure wave within a pipeline. The system also
comprises a mechanism for detecting a reflection wave of the test
pressure wave. The detecting mechanism can be a pressure
transducer and signal processing means or mechanism which process
the pressure signal over time.

Inventor: PUNJ VIKRAM
IPC: H04L12/56
Filed: 1995-11-28
Abstract: Line cards provide an input/output interface between
synchronous communication channels and an asynchronous network. The
input line card translates information received from the synchronous
communication channels into packets for transmission to the
asynchronous network. Each line card generates and stores packets
corresponding to a time frame associated with the synchronous
communication channels. A sequence is selected for the sequential
transmission of packets by each input line card to the asynchronous
network. The cumulative number of packet collisions that would
occur at each output line card during the predetermined time frame
is determined. If the cumulative number of collisions exceeds a
predetermined delay threshold, the number of packets actually
transmitted to the system is reduced preferably by denying service
to new call origination requests. This technique keeps the maximum
cumulative collisions for each output line card within the
predetermined delay threshold.
