Patent EP-1059425-A3 (EP)
Inventor: ELLIOTT ANDREW C
IPC: F01L25/06
Filed: 2000-06-09
Abstract: A pilot control valve for controlling a reciprocating pump having a valve member
shiftable within a valve body between a first or "downstroke" position and a second or
"upstroke" position. When the valve member is in its first position, the valve member allows
communication of control fluid to the lower surface of a piston to move the piston from a first
position to a second position. As the piston reaches its second position, a vent in a rod attached
to the piston allows control fluid acting on the valve member to depressurize. As such control
fluid is depressurized, pressurized control fluid acts on the valve member to move the valve
member from its first position to its second position. In its second position, the valve member
blocks communication of the control fluid to the lower surface of the piston and allows
communication of the control fluid to the upper surface of the piston causing the piston to return
to its first position. As the piston returns to its first position, the vent in the piston rod allows
the pressurized control fluid acting on the upper surface of the piston to act on the valve member
to move the valve member back to its first position. In its first position, the valve member
blocks communication of the control fluid to the upper surface of the piston and allows
communication of the control fluid to the lower surface of the piston and the process is repeated.
In this manner, the pilot control valve of the present invention achieves a consistent pumping
rate for a reciprocating device coupled to the pilot control valve.

IPC: G11B7/22

Abstract: A device for securing an optical element in which, when
an opposing surface of a mold (30) for forming a base (16) is formed
so that a mounting surface of the base is formed at an angle
equal to 90 degrees plus a very small angle (1), the mounting
surface is smoothly formed when the mold is removed from the
base. Therefore, it becomes unnecessary to mechanically cut
the mounting surface, so that it can serve as a reference
surface for directly securing the optical element thereto.
This makes it possible to simplify the manufacturing process
of the base and to reduce costs.

Abstract: An apparatus for measuring ignition charge signals produced by coils of coil-on-plug
devices of an internal combustion engine. A signal detector comprises an insulating substrate
having a first conductive planar layer on a first side and a second conductive planar layer on a
second side. The first layer is coupled to a signal wire and the second layer is coupled to a
ground wire. When the signal detector is held in close proximity to the coil of the coil-on-plug,
ignition signals generated by the coil and passing to the plug are detected. The detected
signals may be coupled to a signal analyzer for display and analysis. The amplitude of the
signal that is output by the signal detector may be adjusted to different coils having different
output signal strengths by modifying the ratio of the surface areas of the first layer and the
second layer.

Abstract: Used oil is treated in a reactor to remove contaminants. The reactor
comprises a rotating vessel housed within a heating chamber. The inside of the
vessel is indirectly heated by conduction through the vessel walls. The vessel
contains a permanently resident charge of non-ablating, coarse granular solids. Within
the vessel, the oil is vaporized and pyrolysed, producing a hydrocarbon vapour. Coke
is formed as a byproduct. Contaminants, such as metals and halides become
associated with the coke. The coarse granular solids scour and comminute the coke
to form fine solids. The fine solids are separated from the coarse solids and are
removed from the vessel. The hydrocarbon vapours are separated from any fine
solids and are routed to a vapour condensation system for producing a substantially
contaminant-free product oil. The contaminant-rich solids are collected for disposal.

Abstract: A technique for detecting and locating a misbehaving router divides the network domain
into multiple sectors and uses a two-level authentication scheme to allow a receiving device to
authenticate that a particular packet originated in a particular sector. More specifically, an
originating device includes a sector tag and a device tag in the packet The sector tag is
computed using a sector key known to all devices in the network domain, and allows any
receiving device to authenticate the originating sector for the packet The device tag is computed
using a device key known only to the device and to a secure and trusted authority within the same
sector. Upon receiving the packet, a receiving device authenticates the packet by computing a
sector verification tag and comparing the sector verification tag to the sector tag in the packet. If
the sector verification tag does not match the sector tag in the packet, then the receiving device
drops the packet. If the sector verification tag matches the sector tag in the packet, but the packet
includes invalid data, then the receiving device forwards the packet to a secure and trusted
authority in the receiving sector. The secure and trusted authority in the receiving sector
forwards the packet to other secure and trust authorities in other sectors. Each secure and trusted
authority that receives the packet is able to determine whether any device in its sector is the
originating device for the packet by computing device verification tags for each device in the
sector and comparing the device verification tags to the device tag in the packet.

Abstract: This invention relates to a phase and amplitude detector (160) required to
identify small signal errors in a signal envelope having a large dynamic range,
especially in the context of linearization of a power amplifier (122) arrangement
employing a pre-distortion technique. A vector generator (300, 352, 372)
responsive to a reference signal    R    (110) produces a frame of reference vectors
   R     1 -   R     n  (274-280) generated by a combination of the reference signal    R    (110) with
first    A    (270) and second    P    (272) offset vectors that provide an amplitude and
phase displacement of the reference signal    R    (110). A signal combiner (290-296,
360-366, 390-396) is arranged to generate difference vectors    E     1 -   E     n  by
combining the frame of reference vectors    R     1 -   R     n  (274-280) and the feedback
signal    F    (124, 150), with the difference vectors    E     1 -   E     n  expressing the phase (p,
254) and the gain (a, 252) error terms relative to the reference signal    R    (110)
and the first    A    (270) and second    P    (272) offset vectors. An error signal detector,
(330-336) responsive to the difference vectors    E     1 -   E     n  and arranged to provide a
measure of the phase (p, 254) and the gain (a, 252) error terms, provides signal
amplitudes that can be combined to generate error signals (182 (Y), 184 X)).
The error signals take the general form:
 X = P 1  - P 2  - P 3  + P 4  = -8 P p R ; 
 Y = P 1  + P 2  - P 3  - P 4  = -8 A a R
