A test kit for determining qualitatively or quantitatively the presence of one or more analytes in a fluid sample, comprising an assay device together with a reading device which engages with the assay device and wherein precisely located engagement of the assay device with the reading device is essential for accurate reading of the assay result, wherein precisely located engagement of the assay d...

A zeolite, designated NU-85, is an intergrowth of zeolites EU-1 and NU-87. The zeolite is a useful catalyst in a wide variety of hydrocarbon conversion reactions including isomerisation and alkylation.

A protective device for shielding an electrical component part during its operation comprises a protective cover (2, 12) preformed of a film-like material in such a way that the preforming conforms to the topography of said component part in predetermined respects, said protective cover being designed so as to envelope said component part substantially from all sides. The basic part of the protect...

A hydraulic system with a pressure source controllable via a load sensing signal, a pressure sink, at least two working sections, each having a hydraulic consumer and a control valve with a load sensing signal connection and at least one back-pressure valve arranged in a tank pipe between the control valve and the pressure sink. In such a system the pressure required from the pump in the neutral p...

A fire-insulation system e.g. for protecting aircraft components against the action of fire, comprises a fireproof metal bulkhead element 13, e.g. of titanium, an insulation element 3 for forming a shield in front of the fireproof bulkhead, and a sheet metal cover 2, e.g. of titanium, integrated into an insulation/ bulkhead member with the insulation element enclosed between the bulkhead element a...

A reduced gain spread spectrum communication system (6) includes transceivers (8) coupled to a base station (10). Each transceiver (8) includes a spreader (28) that spreads a digital packet (26) representing voice using a spreading sequence length smaller than the available spreading gain for a given transmission bandwidth. The spreader (28) can also spread a digital packet (26) representing data ...

An internal combustion engine fuel injector having a selectively openable nozzle (10) through which fuel is delivered to a combustion chamber of the engine. The nozzle (10) comprises a port having an internal annular surface (43) and a valve member (20) having an external annular surface (44) co-axial with respect to the internal annular surface. The annular surfaces are shaped so that when the in...

A laser maintaining and repairing apparatus including a laser oscillator 7, beam guiding apparatus 8 connected to guide a laser beam of the laser oscillator 7, and emitting head 12 for converging the laser beam from the beam guiding apparatus 8 and emitting the beam to a portion to be processed. The beam guiding apparatus 8 includes liquid-tight tubular beam guiding members 9a to 9h. The beam guid...

A nuclear reactor supervision process, monitoring for errors that would affect the stability of a reactor based on a number of systems that affect neutron flow in the reactor core (1), comprises sending out an signal (u) which is replied by an outgoing signal (y) depending on the incoming signal received. The characteristics of the system are determined by measuring the ingoing and outgoing signal...

The parameters detected are the ion current maximum value and its position, the area under the ion current curve, the position of the centre of gravity and the derivative maximum value and its position. The parameters are used for determining the engine load, temperature and combustion quality. - The position of the centre of gravity corresponds to the angle position where the area under the on cu...

The circuit-breaker unit (6) breaks the current feed circuit (9,10) to the apparatus when a unacceptable heat emission condition occurs in the apparatus and is detected by the heat detector (1). The breaker unit is so adjusted that after a specific first time interval it automatically makes a restart attempt for the apparatus by closing the current feed. The heat detector is arranged to monitor th...

Procedure to, in a cellular mobile telephone system, find the cells which constitute potential interferers, i.e. which might interfere if they are allocated unsuitably selected frequencies at planning. A calculation/estimation is made by signal strength in uplink being measured over the frequency spectrum which is used by a certain operator, at which a neural algorithm is used to, on the basis of ...

The protection (13) comprises a rear part (5) and a front part (6) both of rigid material.
