Title: Dual-band antenna coupler for a portable radiotelephone
Inventor: MALDONADO DAVID
IPC: H04M1/725
Filed: 1997-11-25
Abstract: A dual-band antenna coupler (100) for use in an adapter for portable radiotelephone (200). A plurality of curved bands of metal (204a-c) are positioned on a ground plane (102), with at least two of the plurality of curved bands (204a, 204b) of metal being electrically isolated from the ground plane (102) so as to couple radio frequency (RF) signals to and from the antenna (204) of the portable radiotelephone (200). The isolated curved bands (204a, 204b) of metal couple RF signals between the antenna (204) of the portable radiotelephone and first and second matching circuits (602, 604) designed to match the portable radiotelephone antenna (204) at each of the respective frequency bands. A selector switch (606) coupled to the output of the matching circuits (602, 604) selects the appropriate matching circuit output for connection to an external antenna (304). The adapter also includes at least one ground pin (206a-c) mounted on the ground plane (102). When the portable radiotelephone (200) is interfaced with the antenna coupler (100), the ground pin (206a-c) makes electrical contact with a ground reference connection on the portable radiotelephone (202a, 202b, 208).
Patent CA-2276392-A1 (CA)
Title: Sealing arrangement
Inventor: AHVENAINEN ARTO
IPC: F27B7/24
Filed: 1998-01-07
Abstract: The present invention relates to a sealing arrangement between a rotary drum and the stationary end thereof arranged in a material flow in relation to each other. In particular, the invention relates to a sealing between a rotary drum kiln and the feed end thereof, whereby pressurized gas, such as air, is fed to the connecting point of the two in such a way that the angle .alpha. between the feeding direction of the gas and the plane substantially perpendicular to the center axis of the rotary drum is 90~ or less. The air flow is directed to the sealing in such a way that it prevents leaking of process gas and solid matter dust from the connecting point of the rotary drum and the feed chamber and that as little air as possible is directed out to the surroundings. Due to the gas flow, the stationary surface and the moving surface do not rub together.

Patent CA-2281854-A1 (CA)
Inventor: MURAOKA SHINYA
IPC: H04B1/707
Filed: 1999-09-10
Abstract: A UW multiplexing circuit multiplexes a fixed pattern over the leading edge of each frame of transmit data. A spreading code generating circuit generates spreading codes TP1 at a timing synchronized with the frame. A spreading circuit spread-modulates data from the UW multiplexing circuit with the spreading codes TP1. A correlation detecting circuit has spread-modulated fixed patterns as multiplication coefficients, and detects correlations between spread-modulated fixed patterns in received data. A despreading code generating circuit supplies, if a fixed pattern is detected, the leading code of despreading codes RP1. A despreading circuit despread-modulates the receive data with the despreading codes RP1. As a result, the spread spectrum communication apparatus according to the invention is capable of setting the code length and the bandwidth expansion factor independent of each other, and thereby enhancing the performance to detect correlated values.

Title: Water treating device for attachment directly to a hydrant outlet
Inventor: PORTER MICHAEL
IPC: A62C37/50
Filed: 1999-09-22
Abstract: Tap water supply systems are flushed by opening fire hydrants and running potable water through the fire hydrants for a period of time. Since potable water usually contains chlorine, it is necessary to remove the chlorine before the water enters rivers, streams and bays in order to protect aquatic life. This is accomplished by passing the water through a diffuser attached to the fire hydrant, which diffuser contains a mesh bag with a sodium sulfite tablet therein.

Abstract: The invention relates to a message transmission system with frequency dividing optical components. According to the invention, light pulses with different frequencies are coupled out of an optical fibre by means of fibre grating and/or photoionic crystals and imaged by focusing elements outside of the optical fibre. The fibre grating for different frequencies can be arranged in a single period or in different successive periods. The photoionic crystals can be used at the end of the optical fibre or can be etched into a channel or pit in a glass fibre. Additional delay elements ensure that light pulses with different frequencies are imaged at the same time in a predetermined chosen time ratio, in accordance with a parallel reprocessing stage.

Title: Apparatus for extracting a cork from a bottle
Inventor: ALBERT ELIDE
IPC: B67B7/04
Filed: 1999-12-09
Abstract: The present invention relates to a cork extraction device comprising a corkscrew unit and an elongated tubular member. The cork extraction device enables the removal of a cork from a bottle and additionally enables easy removal of the cork from the device upon its removal from a bottle. The corkscrew unit comprises a helical shaped member, wherein one end of the helical shaped member has a handle connected thereto and the opposite end of the helical shaped member is adapted for ease of penetration of a cork. The elongated tubular member has two open ends wherein one end is adapted such that the member can be placed over the neck of a bottle and rest on the shoulders thereof. The opposite end of the elongated tubular member is adapted for the insertion of the corkscrew unit. The internal cross sectional area of the elongated tubular member is sufficient to allow a cork to pass therethrough and exit at either of the open ends. This feature enables the separation of the corkscrew unit and the elongated tubular member when the corkscrew unit has a cork attached thereto. The user is then able to easily restrain the cork during its removal from the corkscrew unit.

Title: Quick-clamping mechanical coupling for a tool implement and method of coupling an implement to an arm
Inventor: WIMMER ALOIS
IPC: F16B17/00
Filed: 2000-05-19
Abstract: The mechanical coupling assembly allows quick and easy clamping of an implement to an arm. The implement carries a bracket which can be received in a coupling member along a given insertion direction. A locking member is rotatably supported on the coupling member and guided transversely to the given insertion direction between an open position, in which said bracket can be freely inserted into the space of the coupling member, and a locked position, in which the bracket is locked to the coupling member. In the locked position, the locking member projects through the bracket.      Fewer than three revolutions, preferably only one and one half revolutions suffice to completely lock and unlock the coupling. The coupling assembly has a cam guide on the coupling member and the locking member is formed with a cam groove. The implement, such as an excavator bucket, can be very quickly clamped to the loader arm, in that the arm is first lowered onto the bucket, the attachment bracket is aligned into the coupling member, and the locking member is rotated through about one and one half revolutions.
