Patent EP-0378325-A3 (EP)
Title: Circuit test method and apparatus
IPC: G01R31/28
Filed: 1990-01-08
Abstract: An analogue circuit or unit under test (34) is tested utilising automatic test equipment (30) and an interface unit (35) to apply stimuli to the circuit (34), the stimuli including supply potentials. A computer (32) analyses the circuit (34) as a network of nodes and modules to deduce a set of ranges of values at selected nodes, the ranges being determined from the set of the stimuli and a resultant set of test measurements, taken from nodes of the circuit by means of the interface (35) and automatic test equipment (30), taking into account tolerances in the stimuli, the measurements and the nominal parameters of components of the circuit. If there is inconsistency among the derived ranges the computer (32) treats as potentially faulty any module which could remove the inconsistency if the constraints imposed by that module were suspended. The computer (32) controls an iterative, hierarchical process involving repetition of the sequence of steps using different sets of stimuli and/or measurements and/or different analyses of the circuit into nodes and modules, in particular with analysis in terms of successively smaller modules. In this way, the location of faults can be progressively narrowed down and corresponding output information can be given in a device (40) such as a VDU or printer.

Title: Method and apparatus for manufacturing fibre-reinforced material
IPC: B29B15/12
Filed: 1990-05-10
Abstract: A method for impregnating fibre bundles with molten 
or liquid resin in the course of manufacturing a 
fibre-reinforced material (which material comprises one 
or more fibre bundles, wherein each fibre is surrounded 
by matrix resin) by impregnating a continuous web 
(10; 10a) of one or more fibre bundles with molten or 
liquid resin (32,33) and solidifying said resin by 
cooling or chemical reaction. During the impregnation 
the molten or liquid resin (35) material is subjected to 
shear forces by bringing it between two closely spaced 
surfaces (10; 10a, 36; 37) which are in moving 
relationship to each other.

Title: Process and apparatus for melting contaminated metalliferous scrap material
IPC: C22B1/00
Filed: 1990-05-25
Abstract: A process and apparatus for melting contaminated metalliferous scrap material are disclosed. The process comprises introducing the contaminated material (11, 72) into a melting furnace (12, 70), heating the material by means of a plasma (13, 71) at a temperature below the melting point of the metal at which the non-metallic contaminants are volatilized in an atmosphere which is preferably inert or has low reactivity with the metal under the process conditions while displacing at least some of the material (11, 72) within the furnace interior, withdrawing volatile contaminants from the furnace (12, 70), increasing the temperature in the furnace preferably while maintaining an atmosphere of low reactivity in the furnace in order to melt the metal while preferably displacing at least some of the material in the furnace interior, and removing molten metal (77) from the furnace. The process allows scrap material to be melted with good metal recovery without the need for separate decontaminating apparatus. The process can also avoid the need to shred the scrap and to add large amounts of fluxing salts to separate the molten metal from remaining dross. A rotary furnace (12, 70) heated by means of a contained arc plasma torch (13, 71) is preferably employed in the apparatus which also preferably comprises an incinerator (21, 79) for oxidizing the volatile contaminants withdrawn from the furnace.

Title: Friction welder having a drive which produces orbital motion
Inventor: SNYDER EDWARD A
IPC: H02K41/06
Filed: 1991-12-23
Abstract: An electromagnetically actuated friction welder produces orbital motion at interfaces between parts (usually of thermoplastic material) to bond the parts by fusion generated by friction. This welder can also be operated alternatively to produce reciprocating vibratory forces thereby providing flexibility as to the selection of an orbital or reciprocating mode, depending upon the joint to be welded. The velocity of motion is controllable preferably around the resonant frequency of the driven structure by adjusting the frequency of the AC power which operates the electromagnetic drive motor of the welder. A plate which carries one of the parts to be welded and which is driven is flexurally mounted for movement in an orbital plane or planes containing the interfaces without substantial tilting by an array of stiff members, such as rods, located around the drive motor, attached to the plate at one end and to a tubular structure at the opposite ends thereof. The tubular structure is desirably attached to a massive support carried by the frame of the welder.

Patent EP-0544064-A3 (EP)
IPC: G01N29/032
Filed: 1992-08-25
Abstract: The invention relates to a procedure for the essentially damping-independent measurement of the density of liquids by means of ultrasound. An ultrasonic (US) beam is emitted by a US transceiver (2) through a measuring chamber (1) towards a US transducer (3), the US beam on its way to the US transducer (3) having to pass, prior to its passage through a liquid whose density is to be measured, a reference reflector (4) which emits a reference echo to the US transceiver (2) which is proportional to the irradiated intensity (i0) of the US beam. The reference echo is utilised to analyse the echo, which contains information on a sound wave resistance discontinuity, between the wall (6) in question of the measuring chamber (1) and the liquid in a liquid chamber (7) of the measuring chamber. This information can be used, once the set intensity (i0) of the US beam is known, to determine the reflection of the boundary layer "wall/liquid" from a single measured echo amplitude. <IMAGE>

Title: Method of vegetable processing
IPC: A23L11/30
Filed: 1992-10-10
Abstract: Processed vegetables are subjected to a fermentation step, preferably in a solution of brine or buffer inoculated with lactic acid bacteria, prior to cooking in fat. The fermentation step lowers the amount of reducing sugars on the surface of the vegetable so that over-browning does not occur during cooking. This also permits the use of vegetables such as carrots which contain relatively high levels of reducing sugars, for example 1.5% by weight.

Title: Data protection method in a passive optical telecommunication system
IPC: H04L9/08
Filed: 1993-01-20
Abstract: To protect the data in a passive optical telecommunications system comprising a common telecommunications facility and a plurality of decentralised telecommunications facilities, a public code is in each case determined from a secret code predetermined in a decentralised telecommunications facility, which public code is transmitted upstream to the common telecommunications facility where it is used for coding secondary code information in order to adapt the decentralised facility to transmission parameters individually provided in the common facility for this decentralised facility and repeatedly changed. The decentralised facilities can calculate new codes from time to time. As transmission parameters, the time-slot allocation in a multiplex frame and also the initial position and/or structure of scramblers can be changed. <IMAGE>

Title: Method for tachycardia discrimination or rate adaptive pacing with multiple sensors
Inventor: BAUMANN LAWRENCE S
IPC: G06F17/00
Filed: 1993-05-17
Abstract: A cardiac discrimination method in which feature values of a heart related signal (e.g., cardiac biopotentials) determined to be non-baseline are compared with feature values of a heart related signal determined to be normal baseline. The feature values are extracted on an event-basis (a periodically), for obtaining feature values of a complex. For each complex, the feature values form a sequence with the value having the largest absolute value for the sequence given special identity as a fiducial point. The normal baseline complexes' characteristic sequence and a non-baseline complex's sequence are aligned according to the fiducial points, and unoccupied positions on the ends of the sequences resulting from the alignment are filled with zeros to create normal baseline and non-baseline vectors. The similarity value and dissimilarity value of the normalized non-baseline vector with respect to the normalized normal baseline vector are determined. The type of tachycardia (VT or non-VT) and consequently the selection of appropriate therapy are determined by the location in a discrimination plane of a discrimination point, the coordinates of which are equal to the similarity and dissimilarity values. In addition, the location of a similarly generated hemodynamic discrimination point can be used to discriminate hemodynamically stable and unstable tachycardias based on the features derived from events in hemodynamic related

Patent EP-0689333-A3 (EP)
Inventor: FOLADARE MARK JEFFREY
IPC: H04W84/02
Filed: 1995-06-14
Abstract: We have recognized that in the prior art, to insure that there is at least
some communication between the calling (101) and called parties (125), when the
called party is unavailable to take a call, the calling party (101) may be connected to
an alternate destination, e.g., a voice messaging system (141), and the caller's
telephone call is considered completed. If the called party (125) thereafter becomes
available, the called party (125) is not connected to the caller's telephone call.
However, in the invention, this problem is overcome by, in response to receipt of an
indication that the called party (125) is available for a caller's telephone call after the
caller's telephone call has already been connected to an alternate destination (e.g.
141 or 143), a) disconnecting the caller's telephone call from the alternate
destination (141,143) and, instead, b) connecting it to the called party (125), thus
interrupting the connection between the caller and the alternate destination.
Optionally, a tone or announcement may be supplied to the caller (101) to indicate
that the called party (125) will now be connected "live" to the caller.

Abstract: Silicon integrated circuits use a crystalline layer of silicon nitride 
(Si 3 N 4 ) in shallow trench isolation (STI) structures as an O 2 -barrier film. 
The crystalline Si 3 N 4  lowers the density of electron traps as compared 
with as-deposited, amorphous Si 3 N 4 . Further, a larger range of low-pressure 
chemical-vapor deposited (LPCVD) Si 3 N 4  films can be deposited, 
providing a larger processing window for thickness controllability. An 
LPCVD-Si 3 N 4  film is deposited at temperatures of 720°C to 780°C. The 
deposited film is in an amorphous state. Subsequently, a high-temperatures 
rapid-thermal anneal in pure nitrogen or ammonia is 
conducted at 1050°C to 1100°C for 60 seconds.
