Patent EP-0890798-A2 (EP)
Title: Heat distribution system filled with heat exchange medium
Inventor: HECKER TOMAS
IPC: F24D7/00
Filed: 1998-07-09
Abstract: The plant has a heat exchanger connected to a heat pump circuit, a medium tank, and a pipe system for heat transmission and absorption. The pipe system (3) is connected to the medium tank (2) on feed and return sides. The heat exchanger (1) is connected to the tank in such a way, that vapourized heat transfer medium from the heat exchanger can enter a steam chamber in the tank. Downpipes (5) are positioned between pipe system and tank, so that condensed heat transfer medium flows by gravity from the pipe system, in the case of heat transfer from heat generator to pipe system; or flows from the tank into the pipe system, in the case of heat transfer from pipe system to cold generator.

Abstract: A system and related method for deploying an electric submergible pumping
system within a wellbore comprises an electric submergible pumping system (20) with
an electrical cable (32) operatively connected thereto. A plurality of sucker rods (28)
are connected together to form a sucker rod string, with one end of the sucker rod string
connected to the electric submergible pumping system. The electrical cable (32) is
attached to the sucker rod string (28) at a plurality of spaced locations by clamping (34)
or banding (36). This deployment system permits the use of relatively inexpensive and
manoeuvrable rigs/cranes for the installation, removal and repair of the electric
submergible pumping system rather than having to use conventional relatively expensive
and large workover rigs.

Inventor: HALL DAVID B
IPC: G01B9/02
Filed: 1998-05-22
Abstract: A system (10) for measuring changes in an
environmental parameter, such as velocity or pressure,
includes an optical signal source (11, 12, 13) for
providing a pulsed, coherent light signal, and an
interferometer having first and second optical legs
(33, 35) of unequal optical path lengths. The signal
is split into first and second beams that are
respectively directed into the first and second optical
legs of the interferometer. A fixed mirror (41)
reflects the first beam received at the end of the
first optical leg (33) . An optical pick-off (51)
includes a movable mirror, positioned to reflect the
second beam received from the end of the second optical
leg (35). The movable mirror is movable in response to
changes in the value of the parameter to be measured.
An optical coupler (38) combines the first and second
beams after they have been reflected back into their
respective optical legs, producing an interference
signal, which is detected by an optical detector (39).
The detector (39) generates an electronic signal having
a value indicative of the value of the interference
signal. The electronic signal is analyzed to correlate
its value to changes in the value of the environmental
parameter to be measured.

Abstract: A brush assembly preferably for a universal motor comprises
a tubular brush holder 13, a carbon brush 33, an arm 31 for
biasing the brush and a spring 85 for biasing the arm. The
brush is slidably mounted in the cavity 21 of the holder. A
stop 61 is formed between the brush and the holder and has a
disengaged position to permit travel of the brush partially
through the inner end 25 of the holder and an engaged
position to limit travel of the brush through the inner end
25 of the holder. The electrically conductive arm 31 is
pivotally mounted on the support and extends through a slot
29 of the holder. A distal end 60 of the brush engages the
outer end 53 of the brush and biases the brush 33 toward the
inner end 25 of the cavity. The spring 85 is connected
between the support 15 and the arm 31 for biasing the arm 31
into engagement with the brush 33. The arm is spaced
outwardly of the end of the slot to apply a bias to the
brush when the stop is in an engaged position. As a result
the brush, when worn out is firmly held between the arm and
the stop to reduce degradation of the arm 33 and commutator
35.

Abstract: Two or more wavelength routers are cascaded together to form a passband filter with low levels
of crosstalk between different channels of a wavelength division multiplexing (WDM) stream.
Cascading wavelength routers is a technique that can be used to efficiently realize wide and flat
passbands, but high levels of cross-talk may result from multi-path interference caused by grating
lobes, which produce unwanted transmission paths between the two routers. Spatial filtering can be
applied to inhibit the propagation of light-energy along the unwanted paths, and it can be implemented
using any suitable techniques including pinholes, reflectors, waveguides, and multi-mode
interferometers (MMIs). The resulting passband filter can be designed to generate levels of crosstalk
similar to those of conventional passband filters that rely on a single waveguide router.

Abstract: During first side printing, a media sheet (38) is fed along a feed roller (22) over
a refeed guide (28) toward a metering roller (30) and into a print zone (18). As the trailing edge
approaches a metering pinch line, the metering roller stops. After a drying time, the rollers
reverse direction. The refeed guide directs the media sheet around the metering roller onto an
inner guide (43) having a reversible roller (46). When the trailing edge of the media sheet
clears the refeed guide, the reversible roller is moved into contact with the metering roller
causing such roller to reverse direction. The media sheet now moves back along the inner
guide onto the feed roller. When the media sheet trailing edge is detected at the feed roller, the
feed roller and metering roller change direction back to the original direction. The media sheet
now is fed through the print zone for second side printing.

Abstract: A fabrication- and temperature-independent power-on reset circuit for
providing improved control over live insertion of integrated circuitry. The reset
circuit includes a comparator having an output terminal and two input terminals,
one positive and one negative. One of the two terminals is coupled to a first
threshold turn-on branch and the other terminal is coupled to a second threshold
turn-on branch. Both threshold branches are referenced to ground but they
supply different initial potentials to the terminals of the comparator. As a result,
one terminal acting as the reference terminal holds the circuit output of the
present invention at a potential designed to halt circuit power-on regardless of
independent enable control pin signals. The other of the two terminals does not
trigger switching of the comparator output until after a common supply power rail
reaches a desired potential at initial turn-on. Referencing of the two threshold
branches of the circuit to ground ensures that fabrication and temperature
vagaries are effectively cancelled out.
