Title: Tape winding devices
Inventor: MOCHIZUKI YOSHIAKI
IPC: G11B15/32
Filed: 1997-08-25
Abstract: A thin ribbon cassette (16) is set on a tape winding device and its vertical-direction position is fixed by a position restricting member (18) provided on a back of a cover for an apparatus body. When the ribbon cassette (16) is thin in correspondence to a narrow width of an ink ribbon (15), a quantity of lowering of a ribbon winding top (5) engaged with a reel (16-1) of the cassette (16) is small. The biasing force of a clutch spring (7) compressed depending on the quantity of lowering of the ribbon winding top (5) is small, the force of a winding drive gear (6) which presses a clutch plate (4-1) through a felt (12) is small, the frictional force of the felt (12) is small, and the torque of the rotational shaft (4) is small. This torque is just suitable for winding an ink ribbon narrower long ink ribbon having a corresponding small tensile strength.    When a thicker ink ribbon cassette (22) is set on the apparatus body, the quantity of lowering of the ribbon winding top (5) is large, and the biasing force of the clutch spring (7) is correspondingly large, so that the torque of the rotational shaft (4) is large in correspondence to a long wide ink ribbon (21). In alternative embodiments, the clutch plate (4-1) is replaced by a clutch plate (20-1) provided on a short rotational shaft (20), with a short ribbon winding top (34) being mounted on the shaft (20) to be axially slidable, but non-rotatable, relative to the shaft (20).      A longer rotational shaft (14) is disposed within the shaft (20) and has an annular clutch plate (14-1) surrounding the clutch plate (20-1), a longer ribbon winding top (30) being mounted on the shaft (14) to be axially slidable, but non-rotatable, relative to the shaft (14) .

Patent CA-2236813-A1 (CA)
Inventor: MCKENNEY DAVID I
IPC: G01V8/12
Filed: 1998-06-09
Abstract: An infrared intrusion sensing system comprises a compound lens having a plurality of lines of focus for focusing infrared radiation that enters the system onto a detector, and a window to allow infrared radiation to enter the system and then be focused onto the detector by a set of curvilinear-shaped mirrors. The detector is located near the focal point of the compound lens elements and curvilinear-shaped mirror elements. An enclosure surrounding the detector provides isolation from insect entry and constitutes an insect exclusion enclosure envelope. The enclosure envelope is a protective volume of space for the optical paths between the lens or window and the detector that prevents the entry of objects about 1 mm in diameter or larger which could interfere with the optical paths. Pigmenting, texturing, and/or contouring the insect exclusion enclosure surrounding the detector is provided for the purpose of absorbing and/or scattering superfluous radiation that is not focused on the detector, thereby minimizing false alarms and providing improved operating performance by the infrared intrusion sensing system. An alternate embodiment provides an insert for the insect exclusion enclosure which comprises the pigmenting, texturing and/or contouring, and permits easy update of an existing sensor systems.
Patent CA-2238169-A1 (CA)
Title: A system for connecting calls on physically distinct servers on an advanced intelligent network
Inventor: MARTZ BASIA MARIA
IPC: H04M3/00
Filed: 1998-05-21
Abstract: A bridge connection is made between interfaces on physically distinct telecommunication servers such that the two ends of the bridge can be used to connect existing calls that are terminated on each of the servers. To provide the bridgeconnection, a call using a standard outgoing T1 trunk on one of the servers is made through the public switched telephone network (PSTN) to an incoming T1 trunk on the other server. The servers reserve a special directory number for such calls. When a bridge connection is required one of the servers is queried for its special directory number. The other server is then instructed to make a call to that number. When the called server recognizes the incoming call as using its special number, it answers the call. The calling server then outpulses information needed by the called server to associate the bridge connection with the pending action. In this manner, calls terminating on distinct servers can be connected without the need for additionalhardware.

Patent CA-2242925-A1 (CA)
Title: Laser oscillator system
Inventor: MATSUO KAZUHIDE
IPC: H01S5/024
Filed: 1998-07-06
Abstract: The heat generated by a laser oscillator is partly radiated toward a frame.  The radiated heat is partly absorbed by a cooling mechanism.  The remaining heat is transferred through a chamber which dissipates part of the heat, to a heat insulating panel, which blocks most of the heat.  The heat generated by the laser oscillator is partly radiated outwardly and reflected by a casing inwardly toward the frame.  The reflected heat is partly absorbed by cooling mechanisms.  The remaining heat is transferred through chambers which dissipate part of the heat, to the heat insulating panel, which blocks most of the heat.  Therefore, any temperature rise of the frame due to the heat generated by the laser oscillator is very small, and the frame is prevented from being deformed due to the heat from the laser oscillator.  Because the frame is not deformed, a laser beam emitted from the laser oscillator is applied to a desired position which remains unchanged.

Patent CA-2247333-A1 (CA)
Inventor: LAREAU JOHN P
IPC: G01N29/265
Filed: 1997-01-09
Abstract: A probe inspects steam generator tubing for defects. The probe includes a transducer which generates a localized ultrasonic Lamb wave. The ultrasonic wave is transferred to the tubing by a coupling medium, such as water, that physically couples the transducer and the tubing. Defects in the tubing reflect the ultrasonic wave to the probe which detects the reflections. The results are thenused to determine the length and depth of such defects as cracks, pitting, and thinning. The localized ultrasonic wave performs and inspection sensitive enough to detect ligaments between crack segments. This allows highly accurate predictions of tubing integrity and rupture strength.

Title: Connector for plastic optical fiber
Inventor: GRIMES GARY J
IPC: G02B6/36
Filed: 1998-12-01
Abstract: An optical connector is disclosed for terminating an optical cable comprising a plastic optical fiber surrounded by a protective jacket. The connector includes a housing having an exterior latch that secures it to an adapter. The latch is constructed as a cantilever with its fixed end positioned toward a front end of the housing. The connector further includes a cable-holding structure that attaches to the jacket of the optical cable in such a manner that the plastic optical fiber connects to an associated optical device without the use of a ferrule. One cable-holding structure includes a guide tube that is made from metal and is pressed, or insert molded, into the back end of one plastic housing. A portion of the guide tube protrudes from the back end of the housing and is crimped onto the optical cable. Here, the optical cable is immovably attached to the housing. Another cable-holding structure includes an extender cap, a spring, and a guide tube having an enlarged diameter at one end. The spring surrounds the tube and presses against its enlarged end. The spring also presses against an interior surface of the extender cap, which inserts into the back end of another plastic housing. Here, the optical cable is movably attached to the housing.

Patent CA-2257540-A1 (CA)
Title: Strip casting device
Inventor: SCHWERDTFEGER KLAUS
IPC: B22D11/128
Filed: 1997-06-05
Abstract: The invention relates to a strip casting plant with a circulating belt. In the cooling area, the belt is sucked against carriers by a negative pressure in the cooler.      Formerly used carriers were designed as supporting rollers and had a profiled surface, the profiling being substantially composed of grooves of a width which corresponded to the width of the portions of larger diameter. This could not sufficiently reduce thermal stresses. The strip curved up from the supporting roller. This worsened heat transfer and imprinted a profile corresponding to the upward curvature onto the thin cast strip. In the strip casting plant according to the invention it is envisaged to arrange the carriers in such a way that, with given mechanical properties of the circulating belt, a deflection that compensates for the thermal elongation takes place between the supporting surfaces.
