Title: A hydrophone
IPC: G01H9/00
Filed: 1989-07-07
Abstract: Inertially insensitive optical fibre hydrophones are described, 
utilising materials and configurations to obtain acceleration 
balanced designs suitable for underwater applications where 
acceleration is a problem. Balancing and/or insensitivity is 
obtained both in longitudinal and axially perpendicular directions. 
Acoustic sensitivity of a coil (2) formed by the fibre is 
maintained by the properties of materials used to provide a rigid 
former (4), encapsulant material (3) and secondary material (6) 
which form the hydrophone.
Patent EP-0400396-A3 (EP)
Title: Metals assay apparatus and method
IPC: G01N23/223
Filed: 1990-05-16
Abstract: The present invention discloses an Fluorescence X-ray 
spectrometry method and device for determining the type and 
quantity of metals elements in metal and metal alloy samples, 
particularly precious metal and precious metal alloy samples. 
The invention provides a method and an apparatus in which an 
object to be analyzed is positioned so that an X-ray beam 
that will be generated will coincide with a measurement point 
on the surface of the object where it is desired that the 
analysis be carried out. The measurement point is exposed to 
an X-ray beam having a diameter of 0.1 to 5 mm, causing 
fluorescence X-ray radiation to be generated which is 
sampled. Spectral analysis of the captured fluorescence X-­
ray radiation is then carried out wherein the intensity of 
selected peaks corresponding to target elements is 
determined, whereby the relative composition of selected 
elements can be calculated, thus providing selective 
quantitative analysis for target elements at the measurement 
point. The relative composition can be calculated by 
performing a computer analysis of the spectrum of the 
captured fluorescence X-ray radiation in which a fundamental 
parametric method is applied to the intensity values for 
peaks corresponding to each target element.

Title: Fuel injector having flat seat and needle fuel seal
IPC: F02M61/18
Filed: 1990-05-30
Abstract: An electromagnetic fuel injector (10) has a raised seat (20) with 
which the needle tip (32) coacts to open and close the injector (10) 
as the injector (10) is operated. The raised seat (20) has an 
annular transverse seating surface (22) surrounding a hole (24) 
through the seat member (14). The hole (24) through the seat member (14) 
has a frusto-conically shaped surface (24a) immediately 
contiguous the annular seating surface (22), and the tip (32) of the 
injector needle (12) is conically shaped. The cone angle of 
the needle tip (32) is greater than the cone angle of the 
frusto-conically shaped hole (24a) in the seat member (14), and the 
needle tip (32) and the annular transverse surface (22) of the seat (20) 
are almost parallel so that the needle tip (32) seats on the 
annular transverse surface (22) of the seat (20) at the rim of the 
frusto-conically shaped hole (24a) when the injector (10) closes. 
The seat (20) is softer than the needle (12) so that the seal is 
initially good and becomes better as the injector (10) is 
operated.

Patent EP-0398595-A3 (EP)
Title: Image derived directional microphones
IPC: H04R3/00
Filed: 1990-05-11
Abstract: Second-order gradient directional microphones, both toroidal and 
unidirectional, derived using a first-order gradient sensor and an acoustically 
reflecting surface are disclosed. The sensor is positioned with its axis illustratively 
orthogonal to and suspended a few centimeters from a large acoustically reflecting 
surface. The resulting sensor image is phase reversed resulting in a transducer that is 
a linear quadrupole. The linear quadrupole can be described by two dimensions; the 
distance corresponding to the sensor's dipole distance and twice the distance from 
the reflecting plane. If the reflecting surface is large enough or if the wall of an 
enclosure is used, the resulting microphone becomes a second-order gradient 
unidirectional microphone. A perfect match between the sensor and its image from a 
good acoustic reflector results in an ideal second-order gradient microphone with 
3 dB beam width of ±33° and no grating lobes below about 3 kHz for a spacing from 
the reflecting plane of about 2.5 cm. Toroidal directional microphones are formed 
using two or more sensors and an acoustically reflecting surface.
Patent EP-0400924-A3 (EP)
Title: Process and apparatus for producing a gas which is substantially free of uncombined oxygen from air
IPC: B01J19/14
Filed: 1990-05-25
Abstract: A process and an apparatus for producing a substantially 
oxygen-free gas from air are disclosed. The process involves 
reducing the oxygen content of air in a first step (e.g. in 
apparatus 10) to 0.5% or more by volume by a non-cryogenic 
physical separation technique, e.g. by means of the use of a 
molecular sieve or a diffusion membrane designed to separate 
oxygen from nitrogen. In a second steps (e.g. in chamber 12) 
the oxygen remaining in the resulting oxygen-reduced gas is 
substantially eliminated by contacting the oxygen-reduced gas 
with an oxidizable material that reacts readily with the 
oxygen (under suitable conditions) without introducing 
oxidizing materials or pollutants into the gas. The preferred 
oxidizable material is a porous bed (21) of carbon particles 
heated to a temperature of 700-900°C or methane as a gaseous 
fuel. These materials introduce carbon monoxide and (in the 
case of methane) water vapour into the substantially oxygen-free 
gas. Carbon monoxide is an acceptable non-oxidizable gas 
for many purposes and, if necessary, the water vapour can be 
removed by condensation. The process can produce an 
inexpensive gas mixture containing less than about 0.1% by 
volume of oxygen which is suitable for many industrial 
purposes, e.g. as the heat transfer medium for a contained arc 
plasma torch (41) used for heating materials (44) containing 
aluminum or aluminum alloys.

Patent EP-0394165-A3 (EP)
Title: Overlapped execution of sequential instructions from a common stream in multiple processors
IPC: G06F9/38
Filed: 1990-03-13
Abstract: A tightly-coupled main processor (110) and coprocessor 
(120) overlap the execution of sequential instructions 
when apparent sequential operation and precise exception 
interrupts can be assured. Logic detects all conditions 
under which these criteria might potentially be violated 
in the coprocessor before it has finished performing an 
instruction, and holds off the main processor from execut­
ing a subsequent instruction.

Title: Series of parts for making internal-external locks for sliding doors, windows and equivalents
IPC: E05B65/08
Filed: 1990-03-13
Abstract: The series of parts for making internal-external 
locks consists essentially of two identical plates (1, 1a), 
obtained from the same basic section (3), reversable 
and combinable within corresponding longitudinal 
slots (2, 2a) made opposite each other on a door or window; 
the plates have respective openings (4, 4a) through which 
it is possible to move corresponding rods (5, 5a) from the 
outside. These rods are housed, and can slide 
within, respective pairs of longitudinal guides (6, 6a) 
which are on the plates on the side facing the door 
or window and have at their ends respective seats (7, 8). 
The rod assigned to the inner part of the door or 
window has, in its first seat, an adjustable 
locking device (10), and in the second seat, a spring 
means (11) which acts on the same rod and moves between 
two extreme stable positions, one a fully unloaded 
position, in which the device is lowered thus 
locking the door or window, the other fully loaded 
under manual action from the outside on the rod, in 
which the device is raised, thus unlocking the door 
or window.

Title: Hierarchical path hunt for multirate connections.
Inventor: FLOOD PAKER MARIANNE
IPC: H04J3/00
Filed: 1993-10-13
Abstract: In a time-space-time switching network that provides connections at a hierarchy of data rates, a path-hunt arrangement effects establishment of a switched connection of a given bandwidth as a collection of a plurality of connections of smaller bandwidths of different sizes. Connections are first found at the highest rate of the hierarchy to satisfy as much of the given bandwidth as possible. Then, connections are found at the lower rates to satisfy any remaining unsatisfied bandwidth. The path-hunt uses a hierarchy of status tables, corresponding to the hierarchy of rates, for each time-switching element of the network. The tables have entries that define availability of time slots -- representing bandwidth of the tables' corresponding rates -- between that time-switching element and a space-switching stage of the network. Connections are provided at the highest rate by finding matching idle time-slot entries in the high rate status tables for the two time-switching elements involved in the connection. Connections are provided at a lower rate by finding matching partially-full time-slot entries in the highest rate status tables for the two time-switching elements and then finding matching idle time-slot entries in the corresponding lower-rate status tables. To maximize path-hunt efficiency while maintaining non-blocking performance, the path-hunt follows a search hierarchy for lower-rate connections that first searches for matching partially-full time-slot entries in higher-rate status tables, and uses idle time-slot entries in higher-rate status tables only as a last resort. <IMAGE>

Title: Anchor-element for fixing an outer cavity-wall part and method for installing such element.
Inventor: GRUEN JUERGEN
IPC: E04G23/02
Filed: 1994-08-23
Abstract: In order to fasten a facing shell arranged at a distance from the supporting shell, the invention proposes an anchorage element which comprises a sleeve, which is enclosed by a sheath and is filled with a bonding composition before introduction into the bore, and an anchorage means for the displacement of the bonding composition. The anchorage means comprises a wire which can be inserted in a longitudinal groove of the plastic part in such a manner that one side of the wire remains free. The diameter of the anchorage means corresponds virtually to the diameter of the sleeve. Consequently, the bonding composition is distributed uniformly in the annular gap and, after the composition has hardened, homogeneous bonding between the bore wall and the anchorage element is achieved. <IMAGE>

Title: Verfahren zur Durchschaltung von Verbindungen bei Anrufen von bzw. zu mobilen Teilnehmern eines zellularen digitalen Mobilfunknetzes
Inventor: STRAKA PETER DIPL-ING
IPC: H04W4/12
Filed: 1995-07-06
Abstract: Dadurch, daß virtuelle Teilnehmer (VSN0, VSN1...) in den
Speichereinrichtungen (HLR, VLR) des Vermittlungssystems eines
Mobilfunknetzes eingerichtet werden, können von den genormten
Steuerungsfunktionen abweichende neue mobilfunknetzspezifische
Funktionen durchgeführt werden, indem der Anruf
vom bzw. zum mobilen Teilnehmer an einen virtuellen Teilnehmer
(z.B. VSNx) gerichtet ist. Der virtuelle Teilnehmer
unterscheidet sich von dem physikalischen mobilen Teilnehmer
dadurch, daß eine Verbindung zu einer Mobilstation nicht aufgebaut
und die Verbindung nur in dem Vermittlungssytem selbst
existiert. Das jeweilige Übertragungsprotokoll braucht nicht
verändert zu werden, da der an den virtuellen Teilnehmer gerichtete
Anruf wie jeder andere Anruf eines mobilen Teilnehmers
behandelt wird. Auch die Übertragungsprotokolle an den
Schnittstellen des Mobilfunknetzes sind davon nicht beeinträchtigt,
da die virtuellen Teilnehmer nur in den Speichereinrichtungen
innerhalb des Vermittlungssystems vorhanden
sind.
