Title: A Doctor for Creping Tissue
Inventor: DIDIER JAMES J
IPC: D21G3/00
Filed: 1995-04-20
Abstract: A doctor (10) is disclosed for creping tissue (T) from a surface (S) of a Yankee dryer (12). The doctor (10) includes a frame (14) and a support (16) which extends from the frame (14). A swing arm (18) is pivotally secured to the support (16) about a pivotal bearing (20). The swing arm (8) defines a further bearing (22). A pivot (24) extends through the further bearing (22) for rotatable movement relative to the swing arm (18) such that the pivot (24) is rotatably supported by the swing arm (18). A doctor (26) is rigidly secured to the pivot (24) for doctoring the tissue (T) from the surface (S) of the dryer (12). A blade (28) is removably secured to the doctor (26), the blade (28) defining an operative edge (30) which cooperates with the surface (S) of the Yankee dryer (12) for creping the tissue (T) from the surface (S) of the dryer (12). A loader (32) is operatively connected to the pivot (24) for rotating the pivot (24) within the further bearing (22) for loading the operative edge (30) against the surface (S) of the dryer (12). A blade angle changer (34) is operatively connected to the swing arm (18) for pivoting the swing arm (18) relative to the support (16), the arrangement being such that movement of the angle changer (34) selectively changes an angle (.alpha.) defined between the blade (28) and the surface (S) of the dryer (12). The operative edge (30) is disposed substantially along an axis of rotation (36) of the pivotal bearing (20), the arrangement is such that when the blade (28) wears due to contact with the operative edge (30) with the surface (S) of the dryer (12), the angle (.alpha.) is changed to optimize the creping without significantly altering the disposition of the operative edge (30) relative to the surface (S) of the dryer (12).

Title: Digital signal receiver
Inventor: TOMONAGA EIICHIRO
IPC: H04N19/44
Filed: 1997-01-15
Abstract: Digital signal receiver for recording a plurality of program streams at the same time period with a single storage medium.  The transport streams from the tuners T11 through T1n are converted into the program streams at the format conversion circuits F11 through F1n, then converted into the data forms corresponding to the data bus 5 in the data bus interfaces IF11 through IF1n, so as to output them to the data bus 5.  Therefore, the data having a plurality of programs at the same time are transmitted on the data bus 5 in a multiplexed state.  The data bus interface circuit 6 restores the data from the data bus 5 into the original data and supplies it to the storage medium 7.  Accordingly, the storage medium 7 is able to record the program streams of a plurality of programs at the same time period.

Title: A technique for substantially eliminating temperature induced measurement errors from a coriolis meter
Inventor: ZOLOCK MICHAEL J
IPC: G01F1/20
Filed: 1992-07-02
Abstract: Apparatus and accompanying methods for inclusion in a Coriolis meter that substantially eliminate temperature induced measurement errors which might otherwise be produced by performance differences existing between the separate input channels contained in the meter. Specifically, two pairs of input channels are used in the meter.  In operation, the meter repetitively measures the internal phase delay of each of these pairs and then subtracts the delay associated with each pair from actual flow based measurement data subsequently obtained therefrom.  While one channel pair is measuring actual flow, the other channel pair is measuring its internal phase delay, with the channels being continuously cycled between these functions.  Because both channel pairs are cycled at a sufficiently rapid rate, the current value of the internal phase delay for each of the pairs accurately reflects any temperature induced changes then occurring in the performance of that pair thereby eliminating substantially all temperature induced error components from the flow measurements subsequently obtained therefrom.  In addition, the meter measures flow tube temperature in a manner that removes temperature induced errors therefrom.

Patent CA-2209295-A1 (CA)
Inventor: SIMKO RICHARD T
IPC: H03K17/10
Filed: 1996-10-09
Abstract: The present invention discloses methods and apparatus for implementing a clocked high voltage switch involving MOS devices (M1-M19). The switching is from a high voltage source typically at 21V to ground. An intermediate voltage source typically at 11V is introduced for reducing the gated breakdown voltage requirement to approximately 10V. This reduced gated breakdown voltage requirement is easily met by special layout methods applied to various transistors in the circuit (M1-M3, M5-M6, M8-M13). The basic layout methods include the terminating of the field implant region near the N+P junction to expose the N+ diffusion over the P substrate to increase the junction breakdown and the gated diode breakdown, and the use of short channel length to reduce the threshold voltage.
