Patent CA-2060638-A1 (CA)
Title: Shutters with integrally molded spring elements for flexible magnetic disc cassettes
Inventor: HUGHES PATRICK M
IPC: G11B23/033
Filed: 1992-02-04
Abstract: ABSTRACT    A flexible magnetic disc cassette includes a cassette case formed of a molded plastics material defining an interior space and a window which opens thereinto.  A flexible magnetic disc having a central hub is rotatably accommodated with the interior space of the cassette case such that the magnetic disc is exposed beneath said cassette case window.  A shutter formed of a plastics material (which may be the same or different than the plastics material form which said cassette case is formed) straddles an edge of the cassette case adjacent to its defined window. The shutter is reciprocally movable along the edge between a closed position (wherein said shutter covers the window) and an opened position wherein the shutter exposes the window to allow access to said magnetic disc therebeneath).  According to the invention disclosed herein, an elongate spring element is integrally molded (unitary) with either the cassette case or the shutter and so as to occupy a position within a corner pocket of the cassette case.  The integral spring exerts a bias force against the shutter in a direction which encourages the shutter to move into its closed position.

Title: Ceramic duplex filter
Inventor: TURUNEN AIMO
IPC: H01P1/213
Filed: 1992-04-07
Abstract: Abstract Previously it was not possible to realize a ceramic duplex filter using a single monolithic ceramic block, because the isolation between the transmitter branch and the receiver branch could not be made sufficiently high. A duplex filter (1) can be realized in ~ single ceramic block by making, be-tween its filters  (A and B), a strip like area (9) on the non-coated surface  (5)  of the ceramic block, due to which the electric and magnetic coupling between the resonators (R4, T1) of filters (A and B) on each side of the area can be adjusted to almost zero. This "electric partition"  (9) provides a sufficient isolation between the filters of each branch.

IPC: F16L33/20
Filed: 1990-08-30
Abstract: New hose construction, new couplings therefor and new methods of making such hose constructions and new methods of making such couplings are provided herein. In one embodiment, an improvement is provided in a hose construction including a tubular hose having an inner peripheral surface and an outer peripheral surface, and a coupling secured to one end of the tubular hose. The improvement is one wherein the innerperipheral surface means of the tubular hose includes an inner corrugated hose which is made of polymeric material and which has inwardly-convex projections with recesses therebetween and which extends from one end of the tubular hose to the other endthereof. In addition, the coupling has an insert which is disposed in one end of the tubular hose and which is radially-outwardly-expanded into sealing relation with the inner corrugated hose. The insert has an outer peripheral surface which is defined by a plurality of outwardly-convex projections with recesses therebetween. Such projections of the insert are respectively received in the recesses of the inner hose. The projections of the inner hose are respectively received in the recesses of the insert. In this way, the interior of the tubular hose is substantially-sealed to the interior of the coupling. Furthermore, the insert includes an inner tubular metallic sleeve and an outer tubular polymeric sleeve which is telescopically-disposed on the tubular metallic sleeve and which has an outer peripheral surface that comprises the outer peripheral surface of the insert. The inner tubular metallic sleeve and the outer tubular polymeric sleeve have been simultaneously-radially-outwardly-expanded in the telescoped relation thereof to provide the sealing relation with the inner corrugated hose.

Abstract: A METHOD AND APPARATUS FOR THE MANUFACTURE    OF A METAL STRIP WITH NEAR NET SHAPE     ABSTRACT OF THE DISCLOSURE   A method and an apparatus for the continuous manufacture of a metal strip (1) with near net shape.          The metal melt (6) is fed from a melt distributor (5) through a casting nozzle (15) onto a rotating, cooled conveyor belt (2) and solidified.  In the operating condition, the melt level is controlled in the melt distributor (5) as a function of the desired strip thickness d of the metal strip (1).  In the melt distributor (5) there is initially adjusted a fill level (A), which corresponds at a maximum with the conveyor belt plane (E).  Such a fill level (B) then is adjusted such that the melt (6) completely displaces the air from the area (11, 14) in front of the casting nozzle (15) and from the casting nozzle (15).  In the operating condition, the fill level (C) is controlled some millimeters above the level (D) of the liquid metal on the conveyor belt (E) so that the melt (6) flows out of the casting nozzle (15) according to the pipette principle.

Title: Method and apparatus for improved twin wire forming
Inventor: KRALL RICHARD J
IPC: D21F9/02
Filed: 1992-03-03
Abstract: ABSTRACT OF THE INVENTION  Disclosed is an improvement to twin wire forming wherein an open support structure in the form of an opened or grilled breast roll or a slotted forming shoe supports at least a portion of the outer wire in the forming throat.   In such manner, the gap between the open support structure and the forming cylinder can be narrowed such that the gap is less than or equal to the thickness of the jet of stock injected between the wire to form the web.   The jet of stock so injected impinges on both the forming cylinder and the open support structure and immediate drainage is provided through the outer wire without substantially varying the tension or radius  of  the  outer  wire  thereby  generally  improving uniformity  and,  in  particular,  improving  basis  weight uniformity of the web produced.

Abstract: A SONET formatter circuit (10) receives a parallel STS-1** TX signal (19) from a highspeed interface module.          The STS-1** TX signal (19), which contains a floating VT group payload, is demultiplexed into seven parallel VT groups (33).  These seven parallel VT groups (33) are converted to serial by a parallel to serial converter (34) and transmitted serially to lowspeed interface modules as DEMUX direction VT group data signals (42, 43).  The SONET formatter circuit (10) also receives serial MUX direction VT group data signals (68, 69) from lowspeed interface modules.  These serial VT group data signals (68, 69) are converted to seven parallel VT groups (89) by a serial to parallel converter (64).          These seven parallel VT groups (89) are multiplexed with overhead data (84) into a parallel STS-1** RX signal (50) which is transmitted to a highspeed interface module.  To maintain continuous VT group frame transmissions, a VT group clock generation circuit (72) is required.
