The invention relates to a shearer loader device (1) used in mining. The shearer loader device comprises a frame (4), which is provided with cutting drums (5, 6) at the ends of the frame and is used to accommodate at least one drilling/anchor-setting unit (2). The drilling/anchor-setting unit is movably arranged on the frame (4) and has end positions in the form of a parking position inside the contours of the frame (4) and a maximum working position outside the contours of the frame (4) and beyond the cutting drums (5).
The present invention relates to a line connector (1) having two flow paths that
are separated from each other for two fluid media, one being for a functional medium,
particularly a urea-water solution in an SCR catalyst system of a motor vehicle,
and one being for a temperature-maintaining medium for maintaining the temperature
of the functional medium. The line connector (1) comprises a connecting body
(2) having at least three line connectors, at least one first connector (4) for
a first line carrying the functional medium, a second connector (6) for a second
line carrying the temperature-maintaining medium, and a third connector (8)
configured as a twin connector for a twin line (10) comprising an inner line (12)
and an outer line (14) substantially surrounding the inner line in a coaxial manner.
The third connector (8) has an inner connecting element (16) comprising an inner
passage (24) and an outer connecting element (18) comprising an outer passage
(26). The connecting body (2) is configured in the interior thereof such that
the first and second connectors (4, 6) pass into the inner or outer passage (24,
26) of the third connector (8) separately from each other. The invention further
relates to a line set consisting of a line connector (1) according to the invention
and at least one connected line for a fluid medium.
The present invention relates to a line connector (1) for media lines, comprising
a connecting piece (2) having at least one connection section (6, 8) for the connection
to a media line (4) or to an assembly, and having a transitional section (10) comprising
a flow channel (11), the section adjoining the connection section (6, 8). To this
end, electrical heating means (12) are provided at least in the region of the transitional
section (10) in an arrangement that at least partially surrounds the flow channel
(11). The invention further relates to an assembled media line comprising a pipe
line having a heating conductor (29) arranged on the circumference thereof,
and a heatable line connector attached to at least one pipe line end of the media
line.
The present invention relates to a preassembled media line with a line connector
(1), composed of a connector body (2) with a connecting section (3) to which a media
line (4) is connected, and with a coupling portion (6) for sealed connection to
a counter-coupling part, the media line (4) being provided with a heating wire
(7) and said heating wire (7) being continued by the connector body (2) and the
media line (4), when connected, in such a manner that it is arranged at least partially
on the coupling section (6). The connector body (2) and the media line (4) are enclosed
on one side by a housing (8) formed particularly from housing shells, the sealing
function and a retaining function being split between the housing (8) and the
connector body (2).

This paper describes the design, fabrication and initial characterisation of a MEMS-based environmental monitoring system. Intended for use with miniaturised Wireless Sensor Network (WSN) motes, the die measures 3 x 3 mm and incorporates humidity, temperature, corrosion, gas and gas flow velocity sensors on a single substrate. Fabricated using a combination of surface and bulk micromachining technologies, the sensor system is designed to replace discrete components on WSN module boards, thereby minimising space consumption and enabling smaller, cheaper wireless motes. Sensors have been characterised over a wide range of environmental conditions. An analysis of the effects of changes in environmental parameters other than the measurand of interest on the performance of the temperature and humidity sensors has been carried out, and corrections applied where necessary. A variety of corrosion monitors have been demonstrated. A gas flow velocity sensor, based on forced convective heat transfer and which has been thermally isolated from the silicon substrate in order to reduce power consumption and improve sensitivity at low flow-rates, has also been presented. The paper also outlines the design of the next generation sensing platform using the novel 10 mm wireless cube developed at Tyndall. (C) 2009 Elsevier Ltd. All rights reserved.
A laser device (1) comprises a ridge waveguide (2) comprising an upper cladding
layer (5) and a lower cladding layer (6), between which is located an active layer
(7). A ridge (8) formed in the upper cladding layer (5) defines the lateral width
of a light guiding region (9) in the active layer (7). The ridge (8) is formed so
that a portion (13) of the light guiding region (9) extends above the active layer
(7) into the ridge (8). A plurality of lateral reflecting slots (15) extend laterally
across the ridge (8) and extend into the ridge (8) to a depth sufficient to extend
into the portion (13) of the light guiding region (9) which extends into the ridge
(8) in order that the reflectivity of each lateral slot (15) is in the order of 2
%. The combined reflectivity of the lateral slots (15) is such that the slots (15)
intersect more than 20 % of the total mode energy in the light guiding region (9),
and this in combination with the gain of the active layer (7) is such as to facilitate
lasing within the light guiding region (9) independently of the reflectivity
of end facets (18,19) of the waveguide (2). Accordingly, the laser device (1)
is particularly suitable for integrally forming with other optical components,
for example, an optical modulator or an optical detector on a single semiconductor
chip, whereby the laser device and the other optical components are formed in
series on the same light guiding region (9).
The invention relates to a connector unit (12) for pressure medium connection between a stationary outer connector piece (10) to be assembled and a spring head (4) of a vehicle gas spring (1) that may be rotated relative to the above over a determined angular range about a spring axis (14), with an inner connector piece (6) to be assembled on the spring head (4) and a line (8) to be connected to the inner connector piece (6) and the outer connector piece (10) that is partly elastically deformable on the relative rotational movement of the spring head (4). The line (8) comprises a deformable section (20) between a terminal line section (18) provided for the inner connector piece (6) and an outer line section (16) for stationary fixing, arranged in an region of the spring head (4), eccentrically radially offset relative to the spring axis. The deforming section (20) has a coil shape with at least one coil axis (22, 24) aligned independently of the run of the spring axis (14).
