Title: Antenna coupler for a portable radiotelephone
Inventor: MALDONADO DAVID
IPC: H04B1/38
Filed: 1997-04-01
Abstract: A novel and improved antenna coupler (100) useful in an adapter for a portable radiotelephone (200). In a first embodiment, a plurality of curved bands (204a-204c) of metal are positioned on a ground plane (102), with at least one of the plurality of curved bands of metal (204a-204c) being electrically isolated from the ground plane (102) so as to couple RF signals to and from the antenna (204) of a portable telephone (200). At least one ground pin (206a, 206b, 206c) is also mounted on the ground plane (102). When a portable radiotelephone (200) is interfaced with the antenna coupler (100), the at least one ground pin (206a, 206b, 206c) makes electrical contact with assembly screws (202a, 202b) or an external ground pad (208) of a battery charging port on the portable radiotelephone (200). In a second embodiment, a coupling pin (404) makes direct contact with a component of the RF chain of the portable radiotelephone (200). In a third embodiment, a helical coupler (504) surrounds the antenna (204) of the portable radiotelephone (200).

Title: Lamp eyelet
Inventor: GALLANT JOSEPH P
IPC: H01J61/36
Filed: 1997-11-28
Abstract: An electric lamp with an enclosed lamp capsule has reduced production manufacturing losses when manufactured with a split eyelet used to duct a lead through the lamp housing. The elongated tube portion of the eyelet has either thinned wall sections or splits formed along the tube axis. When the rivet is set, the tube wall distorts or gives way along the weakened axially lines. The housing glass is then not fractured during riveting, and after riveting the thermal expansion and contraction of the glass with respect to the rivet results in decreased pressure on the glass. The lamp with a split eyelet yields a higher percentage of lamps surviving the manufacturing process, and having fewer cracks or other rivet induced defects in final products.

Title: An improved access to telecommunications networks in multiservice environment
Inventor: LIVERMORE FREDERICK CALDWELL
IPC: H04L12/56
Filed: 1996-07-10
Abstract: In current voice telephony, CATV, and wireless networks, traffic is channelized for both access and transport. This channelization is wasteful of resources where multiple services have varying demands for bandwidth and holding times, or a service generates traffic that is bursty in nature. The invention solves these problems by providing flexible and adaptable multiservice access to the networks. Customer requirements are checked by monitoring traffic on a local access at a connection request and/or during the established connection, and the local access is configured according to the transmission requirements. The local access can also be configured in response to the network information.
Patent CA-2232522-A1 (CA)
Title: Y-spring
Inventor: RELOGIO RIBEIRO ANTONIO MANUEL
IPC: F16F1/18
Filed: 1996-03-27
Abstract: To solve problems where the existing springs do not offer a good solution, at least without using associated mechanisms that increase cost and reduce reliability, a new kind of spring is hereby proposed, hereafter designates as hY-spring. The Y-spring is a leaf spring whose geometry allows for a selflimited deformation, has a chosen initial stiffness and, when the spring is compressed, tends asymptotically to infinity, while the bending moment and the maximum stress at any given section do not overtake a value defined initially as acceptable. An alternate mounting of the same spring allows it to support traction forces and act as a true constant reaction spring. The Y-spring is made of two leafs, usually both curved, rigidly joined together at one of their ends in such a way that the surfaces of both touch each other at that end. The curvature of each of the leafs has the same sign along their entire working length. The curvature and the bending modulus along each leaf are such that the only points to touch each other are the ones in the immediate vicinity of those already touching.

Title: Molten metal pumping device
Inventor: COOPER PAUL V
IPC: F04D7/06
Filed: 1997-12-03
Abstract: A molten metal pumping device is disclosed that comprises a pump base including at least one input port, a pump chamber, and a discharge leading to an output port. A rotor is retained within the chamber and is connected to a rotor shaft. The device further includes a superstructure attached to and positioned above the pump housing, a motor on the superstructure, a drive shaft connected to the motor and a coupling connecting the drive shaft to the rotor shaft. The rotor extends beyond the input port to deflect solid particles thereby reducing jams and preferably is a dual-flow rotor, directing molten metal both into the chamber and out through the discharge. The coupling is flexible and has two coupling members with a flexible disc disposed therebetween. Another aspect of the invention is a housing for a transfer pump that includes a discharge leading to an output port and a button adaptor extending from the discharge. The button is dimensioned so that it can connect to a metal transfer conduit without the use of cement thereby reducing maintenance costs and downtime. Further, the vertical members such as the support posts, metal transfer conduit and rotor shaft, may be sectional so that anti-corrosive materials may be used for the sections positioned in the most corrosive areas of the molten metal furnace. Additionally, a stationary component of the device may be configured to retain a thermocouple.
