Abstract: A method and apparatus for reeling a traveling web (w), such as the paper web produced on a papermaking machine, comprises the concept of winding the on-coming traveling web onto a reel spool (16) which is horizontally supported rotatively, and which, in a preferred embodiment, moves translationally in a direction from the dry end of the papermaking machine towards the wet end of the papermaking machine as the diameter of the wound web roll (20) increases. The reel spool (16) is supported on a pair of spaced, substantially horizontally disposed rails. The on-coming web is first partially wrapped over a segment of a translationally movable support drum (44) with the upper side (wu) of the web facing inwardly toward the surface of the support drum (44). The support drum (44) is selectively nipped, or not nipped, with the web over the web roll (20) as it is commenced to be wound in a winding position, and continues to be wound into a web roll (20) on a reel spool (16). As the web roll (20) being wound increases in diameter, it is translationally moved upstream while being supported on the substantially horizontally disposed rails, and while torque is maintained on the reel spool (16).

Patent CA-2207448-A1 (CA)
Title: Recuperative steam cooled gas turbine
Inventor: BRIESCH MICHAEL SCOT
IPC: F01K23/10
Filed: 1995-10-25
Abstract: A recuperative steam cooled gas turbine in which steam used to cool the turbine section is subsequently introduced into the combustors, thereby recuperating the heat absorbed by the steam during cooling. The steam is generated in a heat recovery steam generator and then directed to a manifold within the turbine shell. From the manifold, the steam flows through passages formed within the interior of the vane by a baffle, thereby cooling the vane and heating the steam. The steam is then discharged from the vane into a chamber that collects the compressed air from the compressor. In the chamber, the heated steam mixes with the compressed air and the air/steam mixture then flows into the combustors, where it serves to reduce NOx generation from the combustors and increase power output from the turbine.

Filed: 1996-01-15
Abstract: A steel tie (20) for incorporation in a rail track has rail fastening devices consisting of a pair of opposing longitudinally extending shoulders (51, 52) adapted to accommodate the rail flange (48) between them.  Each shoulder (51, 52) has a downwardly facing abutment surface (77), and a resilient rail clip (53, 153) that bears upwardly on the abutment surface (77), an end portion (86, 186) that extends inwardly from the abutment surface (77) and bears resiliently on the upper side of the flange (48) for restraining the rail (22) against vertical movement. A further form of rail clip (301) is in the form of a bent rod that is symmetrical about a vertical plane extending laterally of the rail (22). A further bent rod clip (401) has limb portions (406, 407) extending transversely of the rail (22) and inner and outer portions (407, 403) adapted to bear on the rail flange (48) and on a bearing surface (64), respectively. The limb portions consist of an upper pair (406) and a lower pair (404), and as a result of upward pressure exerted by the rail flange one pair (406) is displaced into contact with the other pair (404) to provide a load bearing cross section of increased depth providing increased strength and bending stiffness. A rail tie plate (201) suitable for attachment to a wood tie, has a pair of upstanding abutment members (204) to accommodate a rail (22), each having an upwardly facing lower ramp surface (227) to facilitate insertion of a rail clip (53, 153).

Title: Circuit for causing fpll to lock in desired phase
Inventor: LEIF OTTO W
IPC: H03L7/087
Filed: 1997-08-12
Abstract: A biphase stable FPLL includes a lock switch, operated in response to a frequency lock condition, that forces a predetermined voltage on the input of the third multiplier to guarantee that the loop locks up in a phase that produces a desired polarity of demodulated signal.  A frequency lock indicator operates the lock switch to force the predetermined voltage on the third multiplier irrespective of the actual lock up phase of the loop.  If the lock up phase is wrong, the voltage reversal causes the VCO to slip 180° in phase and the loop locks up in its other bistable state.

The interior surface of the control panel (14) and chambers (10) is selectively coated with a release material (31, 56) to prevent closure of the conduits (30) and enable coplanar sealing of the chambers (10) onto the panel (14) about the perimeter of the apertures (38, 38') and orifices (29) when disposed in registered relation.
Patent CA-2225606-A1 (CA)
Inventor: SATAKE SATORU
IPC: G01G11/00
Filed: 1997-12-23
Abstract: An impact type flow meter for a particulate material such as cereal comprises a supply device for dropping the particulate material, an inclined load detection plate for receiving the dropped particulate material, and a load detector for detecting a load of the particulate material exerted to the load detection plate.  A bottom surface of the supply device is inclined at substantially the same degree with the load detection plate, and has at its lower end with a supply opening for dropping the particulate material onto the load detection plate.  The bottom surface serves to guide the particulate material to the load detection plate at substantially the same inclination therewith.  Thus, the flow meter has a buffer device for softening a dropping impact of the particulate material integrally incorporated in the particulate material supply device, and accordingly, the height is low and the whole apparatus is compact.  The particulate material impinges upon the bottom surface of the supply device, diverges width-wise thereof and reaches the supply opening.  Accordingly, the direction and position of dropping of the particulate material onto the load detection plate are fixed.  Further, the flow-down speed of the particulate material is lessened, unevenness of the speed is averaged or uniformed, thereby the flow meter is high in measurement accuracy.

IPC: B29D22/00
Filed: 1998-04-21
Abstract: The present invention relates to a polyester polymer composition containing graphite in the range of about 3-60 parts per million based on the polyester. The size of the graphite particles is greater than about 0.5µm. As an upper limit, however, any particle size which is not visible to the naked eye is acceptable. Such polyester polymers having graphite incorporated therein absorb infrared radiation better than polymers containing no graphite and thus in the production of plastic bottles less energy is required to heat the preform so that it can be blow molded into a bottle.
