Patent EP-1087245-A3 (EP)
Inventor: STRASSER THOMAS ANDREW
IPC: G02B6/34
Filed: 2000-09-11
Abstract: A compensation arrangement for addressing the problem of first-order and
second-order polarization mode dispersion (PMD) in an optical fiber communication
system includes separate, independent elements for each type of PMD. First-order
PMD may be compensated using conventional techniques related to adjusting the transit
time differential between the polarization states. The second-order polarization mode
dispersion is compensated by recognizing the separate sources of second-order PMD
(pulse broadening analogous to chromatic dispersion, additional pulse broadening due
to optical filtering (narrowing), and coupling of a portion of the optical signal into the
orthogonal polarization relative to the main pulse with a different transmit time). A
chirped fiber grating with a variable temperature gradient, a complementary optical
filter with variable spectral transmission and a polarizer, respectively, can be used to
compensate for these three sources of second-order PMD.

Abstract: A wireless communication apparatus includes an ISDN
interface, an RF unit, and a digital phase-lock loop. When
synchronization with the digital line has been established,
the digital phase-lock loop counts a clock from the RF unit
on the basis of the clock of the ISDN, extracted by the ISDN
interface and the output of the digital phase-lock loop, and
outputs a clock, so that wireless communication is performed
in synchronization with the output of the digital phase-lock
loop. When synchronization with the digital line has not
been established, the digital phase-lock loop frequency-divides
the clock from the RF unit in order to generate a
synchronization clock for wireless communication.

Abstract: A threaded connection between a first part (2) with a recess (4) which opens
outwards, and a second part (3), incorporates a through-screw (7) which has
screwed onto it a nut (8) which is intended to be insertable in the recess (4)
between mutually facing flanges (5,6) situated in the recess. The nut (8) can,
by turning the screw (7), be brought to a locking position under the flanges,
which may be followed by tightening the screw to achieve locking against the
flanges. The screw (7) has between its head (10) and its thread (11) an
unthreaded portion (12), the length of which is greater than the thickness of the
second part (3) at the screw hole (13). This means that the nut cannot be
screwed to abut unintentionally against the second part (3), thereby preventing
incorrect fitting.

Abstract: A lubrication apparatus for an anti-rotation assembly of an
oiless rotary scroll compressor is disclosed. The scroll
compressor includes a stationary scroll element and an orbiting
scroll element which orbits about the stationary scroll element in
a non-rotational fashion. At least one anti-rotation assembly is
provided for preventing relative rotation between the orbiting and
stationary scroll elements. The anti-rotation assembly, which
includes a first rotational bearing component mounted on the
interior of the housing, a second rotational bearing component
mounted on the orbiting scroll element and an offset crank member
interconnecting the first and second rotational bearing components,
is lubricated via a lubrication channel. The lubrication channel
extends from a lubrication port disposed on the exterior of the
housing, through the first rotational bearing component, thereafter
through a channel provided in the offset crank member, thus
allowing the lubricating agent (e.g., grease) to reach the second
rotational bearing component. The provided anti-rotation assembly
can thus be periodically lubricated without significant contact
between the lubricating agent and the gas being compressed (e.g.,
air or refrigerant). Accordingly, any possible contamination of
the exiting compressed gas is significantly reduced.

Abstract: A covering for an architectural opening includes a new system for mounting
the controls for the covering within the head rail such that suspended vertical vanes
are closely positioned relative to the bottom of a head rail and disposed so as to form
a continuous and integrated look with the head rail. An improved pantograph is used
in the control system with one set of links of the pantograph having tapered side
edges to improve stacking of the vanes adjacent to the end of a head rail without
sacrificing strength and therefore quality of the control system. An improved
operating system in the form of the combination of a tilt wand, coupler and pull cord
provides a simplified system for not only moving the vanes along the length of the
head rail between extended and retracted positions but for also pivoting the vanes
about longitudinal vertical axis between open and closed positions. An improved
system for connecting suspended vanes to the control system is also provided with
the system being uniquely designed for use with tubular vanes and retains the vanes
in a tubular orientation. The tilt wand is connected to the tilt rod within the head rail
by an inclined drive connector that enables the tilt wand to be aligned with the pull
cord at the location where the pull cord drops from the head rail for manipulation by
an operator. In this manner, the combined tilt wand and pull cord establish a
substantially child-proof operating system for the covering.
