Title: Closure cap with anti-tamper strip
Inventor: BOESL UDO
IPC: B65D41/32
Filed: 1996-02-01
Abstract: The invention concerns a closure cap with a tearable anti-tamper strip. Flaps extend radially inwards from the inside surface of the anti-tamper strip towards the cap base. With the closure cap in position on the container mouth, these flaps engage beneath a circumferential bead on the container mouth. In order to enhance the stability and resistance to bending of the flaps, their lateral edge areas are directed inwards in such a way that, at at least one position, they possess a lesser distance in relation to the cap axis than the flap centers. The facing surface of the flaps is directed towards the cap base and is inclined towards the cap axis so that, on opening of the closure, the effective force impinges on the centre of the flap relatively far out.      The centre of the flaps is here preferably designed to be thicker than its lateral edge area.

Patent CA-2189701-A1 (CA)
Inventor: CHAVEZ DAVID LEE JR
IPC: H04M3/42
Filed: 1996-11-06
Abstract: A PCS switching system and wireless set that allow the wireless set to control the processing of incoming calls regardless of whether the base station on which the wireless set is registered has capacity to complete a call to the wireless set. When an incoming call is received for a wireless set, a central computer providing overall control of the PCS system directs this call to a paging zone controller of a paging zone in which the wireless set is registered on a base station. If the base station does not have capacity to handle that call, the paging zone controller transmits a page pending message via the base station and a paging channel to the wireless set informing the wireless set that a page is pending and that the wireless set must find a base station with idle capacity. If the wireless set cannot find a base station with idle capacity within the paging zone, the wireless set transmits to the PCS switching system via the paging zone controller a page pending response message that specifies the operations that the PCS system is to perform with respect to the incoming call. The wireless set can specify the call coverage system to which the incoming call is to be routed. In addition, The wireless set can specify a message that will be given to the calling party of the incoming call by the call coverage system. The wireless set can specify that the incoming call is to be placed on hold until the wireless set can find a base station having call capacity to complete the incoming call to the wireless set.

Patent CA-2192287-A1 (CA)
Inventor: PAEZ JUAN BAUTISTA
IPC: A61F2/64
Filed: 1996-12-06
Abstract: A leg brace and method for forming thereof is provided. The brace includes a frame formed of at least a thermoplastic material. A harness is fixed to the frame, the harness being retained adjacent a user's leg during use. The leg brace may be further formed with a tibial restricting portion running along and substantially parallel to the medial shaft of a user's tibia during use, thereby preventing any unwanted movement or rotation of the user's tibia. The brace is formed by forming a brace core of a mixture of a thermoplastic material and a blowing agent and then placing a composite material in contact with the core. Next, the core and composite material are heated in a mold to a temperature sufficient to allow the thermoplastic material to become molten, causing the blowing agent to expand and force the composite material against an interior wall of the mold cavity and to form a thermoplastic cellular core. Next, after cooling, the leg brace is reheated to a temperature sufficient to allow the thermoplastic material to become malleable, but not sufficient to destroy the structural integrity of the leg brace, and then the leg brace is reshaped for a custom fit.

Patent CA-2198088-A1 (CA)
Inventor: MACDONALD PERRY A
IPC: H01P3/08
Filed: 1996-07-01
Abstract: A microwave/millimeter wave circuit structure supports discrete circuit elements (2) by flip-chip mounting to an interconnection network (10) on a low cost non-ceramic and non-semiconductor dielectric substrate (2), preferably Duroid. The necessary precise alignment of the circuit elements with contact pads (14) on the substrate network required for the high operating frequencies is facilitated by oxidizing (20) the interconnection network, but providing the contact pads from a non-oxidizable material (14') to establish a preferential solder bump (8) wetting for the pads. Alternately, the contact bumps on the flip-chips can be precisely positioned through corresponding openings (28) in a passivation layer (26) over the interconnection network.  For thin circuit substrates that are too soft for successful flip-chip mounting, stiffening substrates (24) are laminated to the circuit substrates.  In a self-contained antenna application in which two of the circuit substrates (32, 36) are laminated together, with an antenna (34) on one side and circuitry on the other side, a metallic ground plane (56) between the substrates also serves a stiffening function.
