Patent CA-2191376-C (CA)
Title: High frequency apparatus
Inventor: BRIDGES MARK
IPC: H01P1/00
Filed: 1996-11-27
Granted: 2005-02-22
Abstract: In high frequency apparatus such as for example an rf resonant cavity or a waveguide, it is often necessary to include a slot to permit a probe or other member to be located in the high frequency region and be moveable along the slot. Sealing means arranged adjacent to the slot and around the probe permits movement of the probe whilst minimising the open aperture area of the slot, hence preventing or reducing leakage through it. In one embodiment of the invention, the sealing means comprises a metallic mesh and in another it includes an elastomer material which is loaded with metallic material and/or carries a metallic mesh.

Abstract: Un connecteur A comprend une pluralité de conducteurs. Chaque conducteur se compose d'un contact 1, d'un élément de pièce de terminal 2, et un conducteur de connexion 3 reliant le contact 1 avec l'élément de pièce de terminal 2. Les conducteurs sont tenus respectivement sur un corps 10 du connecteur. Les conducteurs de raccordement 3 sont disposés en trois couches dans une relation de position qui peut les empêcher de se court-circuiter mutuellement et peut également empêcher une diaphonie de se produire entre eux. Dans cette structure, les conducteurs de liaison 3 sont disposés en deux ou plusieurs niveaux, ce qui rend plus facile pour le connecteur d'être conçu pour la prévention de la diaphonie par rapport à une structure dans laquelle les conducteurs de liaison 3 sont disposés dans un plan.

Title: Compacted-powder opposed twin-helical gears and method
Inventor: HINZMANN GERD
IPC: B22F3/03
Filed: 1997-05-09
Granted: 2007-01-09
Abstract: A multiply-acting powder metal press is disclosed for making green form double helical gear compacts. The press has inner and outer lower punches, and an upper, outer punch. The upper and lower outer punches have left hand and right hand external helical profiles as chosen to produce a desired helical gear. The punches co-operate with left hand and right hand helical dies carried by the press about the punches. The helical faces require that the dies rotate relative to the punches during operation.      A cam and roller mechanism may drive this rotation.      The compact forming process commences with an open position in which powder is introduced to a vacant lower die cavity. The upper portions of the press advance downward to close the cavity. All pans of the press except the lower inner, or transfer, punch then move downward at the same speed to transfer powder to the extremities of the cavity. When transfer is complete both lower punches may be stopped, while the upper punches continue to advance. The dies advance at half the speed of the upper punches, rotating partially as they do so. Once the powder reaches its compacted density the upper and lower punches cease motion, but their dies continue to tum, separating themselves and compressed part. Finally, the part is ejected and the press returns to the initial condition.

Title: Method and network component for switching low bit rate connections between input modules and output modules in a communication network
Inventor: TIPPMANN-KRAYER PETRA
IPC: H04L49/111
Filed: 1998-12-21
Granted: 2007-07-10
Abstract: In a method and network component of a communications network for switching connections of low bit rate between input modules and output modules, the input modules and the output modules form a first switching level, and an ATM switching stage arranged between the input modules and the output modules forms a second switching level. In the first switching level, a number of low bit rate connections at the input module, which are to be transmitted to the same output module, are respectively merged by the input module into at least one ATM connection. In the second switching level, the switching through of the ATM connections for transmitting data in ATM cells ensues by the ATM switching stage. Subsequently, in the first switching level, the ATM connections which have been switched through are converted by the output module into the low bit rate connections. The combined switching in two switching levels represents an especially economical solution for functions specific to mobile radio and switching applications dealing with low bitrate traffic, by simultaneously assuring an acceptable speech quality with good exploitation of the ATM bandwidth.
