Title: Radiotelephony system
Inventor: HART GEORGE MAYNARD
IPC: H04B7/26
Filed: 1992-01-15
Granted: 1997-12-02
Abstract: A multichannel radiotelephony system provides two way   cordless   communications   with   a   plurality   of multichannel transceivers portable within a coverage area comprised by a plurality of cells, each associated with a base  station  and  antennas,  such  as  to  permit  channel frequency reuse in cells within the coverage area.  For at least part of the coverage area,  the locations of the antennas within the cells and the locations of the base stations  are  independently  mapped,  the  antennas  being associated with active  antenna  systems  and  the  active antenna  systems  being  connected  to  the  base  stations utilizing broadband transmission by means of a fixed bi-directional signal distribution network.   The network is connected to the base stations and the antenna systems through  suitable   interfaces   incorporating   frequency translation so that available frequency bands in the signal distribution network which will normally be shared with other services, may be utilised.  Plural base stations may be co-located.  The radio link to the transceivers may be frequency or time division multiplexed, but communication over the network will normally be frequency multiplexed, using separate bands for transmission and reception.
Patent CA-2061871-C (CA)
Inventor: GROSSMAN STANLEY J
IPC: E01D2/02
Filed: 1992-02-26
Granted: 1995-08-22
Abstract: A composite, prestressed structural member,  such as a bridge unit and methods of forming such a member.   The apparatus includes a plurality of longitudinally extending girders which are transversely spaced and a plurality of adjacent composite units disposed on the girders.  Each com-posite unit has a plurality of beams with a molded deck por-tion  formed  thereabove.     The  beams   are  positioned transversely  with  respect  to  the  girders  and  attached thereto.   Additional, longitudinal beams are disposed bet-ween the transversely extending beams over the girders.  The longitudinal beams are attached to the girders and by con-nectors to the molded deck.   The structure is formed by positioning the girders on a construction support adjacent to a center portion of the girders such that the free ends of the girders cantilever and deflect downwardly.  The beams of the composite units are attached to the girders in this construction position.  Any gaps between adjacent composite units are filled with a non-shrink,  high strength grout.          When moved to an operating position wherein opposite ends of the girders are supported,  the natural deflection of the unit  due  to  its  weight  imparts  a  compressive  prestress longitudinally in the molded deck units.  Each molded deck unit  may  be  formed  such  that it  is  also  transversely prestressed.

Title: Surge protector for telecommunications equipment
Inventor: HUNG FRANCIS YUN-TAI
IPC: H01C7/12
Filed: 1990-10-02
Granted: 1997-04-15
Abstract: A protector for protecting equipment, especially telephone equipment, against high voltage and/or current surges such as are caused by lightning in the vicinity of the equipment or the cables to which it is connected, comprises one or more overvoltage pro-tectors (42, 58; 234, 236) mounted upon one face of an insulating support (18; 218). A generally planar contact member (62; 290, 312) mounted upon the support member has a ground contact member (90; 296) to make contact with a ground electrode (114; 310) in the equipment to be protected and with each overvoltage protector. A spacer (60; 320, 322) of fusible plastics material cou-pled thermally to the protection device melts when a sustained fault occurs. As the spacer melts, it permits an electrical connect tion between the contact member and the line to which the over-voltage protector is connected, effectively short-circuiting the line to ground. Overcurrent protection may be provided by means of a resistor (116) disposed in series with the line and located close to the plastics spacer so as to heat the spacer when an overcurrent occurs. In one case, the spacer comprises a film (60) interposed directly between a pair of contacts (40, 74') which serve to short-circuit the protector. In another case, the spacer comprises a limb (324) with relatively thin lateral projections (328, 338) which melt and shear. In both cases, the spacer preferably comprises high density, high molecular weight polyethylene.

Inventor: FAUST ALISON MARIE
IPC: G02B6/245
Filed: 1992-08-07
Granted: 1997-04-01
Abstract: A cutting tool and method of using the same provide for cutting the protective elements of a monotube-type optical fiber cable without severing the buffer tube in order to access the buffer tube and the optical fibers found therein.
