Patent CA-2239401-A1 (CA)
Title: Telephone test set line cord strain relief attachment assembly
Inventor: ZOISS EDWARD J
IPC: H04M1/15
Filed: 1998-06-02
Abstract: A line cord strain relief attachment assembly facilitates insertion and replacement of a two conductor line cord terminated by relatively small geometry terminal lug connectors, rather than a larger modular style multiconductor connector, such as an RJ-45 plug. The line cord strain relief attachment assembly includes a cylindrically configured strain relief element, made of a suitable flexible and waterproof material and having a flange spaced apart from one end of the element. The strain relief element has a diameter proximate to that of a circular aperture in a rear wall of the test set. Adjacent to the one end of the strain relief element its cross-section is reduced to form a sloped recess region. A line cord retention wedge has a slot which conforms with the recess region of the strain relief element. The slot is bounded by opposing ramp-configured walls, that are sloped to conform with the sloped surface of the tapered recess region of the strain relief element. As a result, when the line cord retention wedge is inserted into the test set and engages the sloped recess region of the strain relief element, the strain relief element is drawn into the aperture of the test set, bringing the flange of the strain relief element into sealing engagement with the external surface of the test set.

Title: Method for making three-dimensional, macroscopically-expanded webs having improved functional surfaces
Inventor: AHR NICHOLAS ALBERT
IPC: A61F13/511
Filed: 1996-12-13
Abstract: The present invention provides a process for forming a three-dimensional, macroscopically-expanded, fluid pervious web (70) having an improved functional surface comprised of a sheet of polymeric material having a first surface and a second surface. A plurality of discrete deposits of a water resistant resinous material having a pre-determined open time are deposited on the first surface of the sheet. The deposits of resinous material are drawn upwardly from the first surface of the sheet to form corresponding fibrils (54) during the open time. After resinous material has cured, the sheet is fed onto a forming structure having opposed surfaces such that the sheet is in contact with the forming structure. The forming structure exhibits a multiplicity of apertures which place the opposed surfaces of the forming structure in fluid communication with one another. A fluid pressure differential is applied across the thickness of the sheet which is sufficiently great as to cause the sheet to rupture in those areas coinciding with the apertures in the forming structure and to conform with the forming structure while substantially maintaining the orientation of the fibrils (54).  The printing and drawing steps are preferably accomplished via a screen printing roll, and the fluid pressure differential preferably comprises a high pressure jet of liquid.
Patent CA-2241098-A1 (CA)
Inventor: JAKAB GYULA
IPC: H04B3/00
Filed: 1998-06-19
Abstract: The present invention relates to a method and apparatus for separating a low frequency voice signal from a high frequency data signal propagating on an analog loop connecting the central office of the PSTN to a CPE. The apparatus includes a low pass filter connected in series with the tip and ring conductors of the analog loop to extract the voice signal. The apparatus also includes a high pass filter to reject the low frequency voice signal, leaving only the higher frequency components. The high pass filter features a transformer including two balanced primary winding sections, one section being in series with the tip conductor and one section being in series with the ring conductor. A junction circuit is coupled to the high pass filter to provide the signal exchange functionality needed to separate the transmit and receive components of the high speed data signal. The junction circuit includes a transmit component output coupled to a secondary winding section of the transformer for passing the transmit component applied to a transmit component input of the junction circuit to the analog loop through the transformer of the high pass filter. The junction circuit also includes a composite signal input for receiving a composite signal from a second section of the secondary winding that is a combination of the transmit component and the receive component. A processing circuit in the junction circuit extracts the receive component by canceling the transmit component in the composite signal.

Inventor: GARZA-TAMEZ FEDERICO
IPC: E02D31/08
Filed: 1998-07-10
Abstract: A stabilization system protects a structural member from  the  effects  of  seismic  disturbances.  Pendular isolators are positioned between a structure fixed to the ground and the structural member,  which is movable and which  is  sought  to  be  protected,  such  as  a  complete building, a building slab upon which sensitive equipment is used, or a bridge deck. The pendular isolators can be rods extending between the building and the slab floor, wherein ends  of  rods  connected  to  the  slab  floor  include  a spherical friction knuckle joint or bearing, i.e., knuckle element/socket  assembly.  Alternatively,  each  pendular isolator can be a set of supports movable relative to each other and connected by at least one rod having a knuckle joint at each end thereof.   The friction at the knuckle joint is utilized to provide a damping of the seismic disturbance,  thereby  permitting  only  limited  relative movement  between  the fixed  structure  and  the  movable structural member in the event of a seismic disturbance. The lengths of the pendular isolators are adjustable.
