Patent CA-2059304-A1 (CA)
Inventor: YAGUCHI OSAMU
IPC: H02H7/085
Filed: 1992-01-14
Abstract: ABSTRACT OF THE DISCLOSURE            A DC power supply for a DC motor is controlled by a drive transistor.  An "ON" state of the drive transistor is maintained by a comparator or means which compares a terminal voltage at a point between the DC motor and the drive transistor with a reference voltage supplied from the power supply.  A clock pulse is applied to the drive transistor to make it periodically turn off in order to detect an induced voltage depending upon rotation rate of the DC motor.  The drive transistor returns to turn off upon stopping the rotating DC motor by force.          A regulator is provided between the power supply and the reference voltage.  A restraint torque and a rotation rate control means are also provided.          Alternatively, a pulsating power supply is provided instead of the DC power supply and the clock.

Title: Method for decoding television signals
Inventor: MONTA PETER A
IPC: H04N7/01
Filed: 1991-04-29
Abstract: A method for decoding National Television System Committee (NTSC) signals which exploits redundancies in film-to-NTSC transcoding, known as "3-2 pull-down". The decoding method estimates luma (Y) and chroma (C). The "3-2 pull-down" structure assigns three NTSC  fields to one frame of a film frame pair, and two NTSC fields to the other film frame. Luma and chroma in different film frames are separated using different methods, and the separated signals are better than the separated signals achieved using conventional one dimensional and two dimensional NTSC decoding methods. The new method for separating luma and chroma from composite NTSC  signals can be combined with an interlace-to-progressive method (22), which converts the decoded 3-2 NTSC signals (20) to two film frames, and an upconversion procedure (24), to yield improved image quality.

Title: Switch for use as a vertically mounted cut out or in-line switch
Inventor: WEBB THOMAS H
IPC: H01H31/12
Filed: 1992-06-18
Abstract: ABSTRACT OF THE DISCLOSURE A switch, for an electrical transmission line, can be used as a vertically mounted cut out or as an in-line switch.  The switch has an insulator, mounting bars at either end, and a first and second brackets extending from the mounting bars.   Brackets  are configured  to receive  a  fuse  element,  which  can  be  of  known construction.  A first bracket includes a pair of bracket elements that defines slots for receiving pivot lugs of the fuse element.  To enable the switch to be used either vertically as a cut out or horizontally as an in-line switch,  the bracket elements  are movably,  preferably rotatably, mounted to the first bracket.   The bracket elements can then be located so that the slot is always at least partially directed upwardly.  Then, for either use, the fuse element will always be retained by its pivot lugs in the slot.  To enable the switch to be mounted as an in-line  switch,  the  insulator  can  be  provided  with  a relatively narrow central  portion  to  its  body and  a removable clamp.   The clamp would be  used  for  such vertical mounting, and would be removed for use as an in-line switch.

IPC: G01R31/00
Filed: 1991-11-06
Abstract: An automated test system (10) makes voltage and resistance measurements. A breakout cable (34) is connected between the vehicle electronic control module (30) and the vehicle sensors and controls (32). Resistance measurements are made between a selected pair of connector pins of the breakout cable (34) by connecting a current loop (50) which includes a power supply (56) and a known resistance (R1, R2) through a first multiplexing circuit (70, 72) to the selected pair of pins. A voltage measuring circuit (52) measures voltage across the known resistance (R1, R2) and between the pair of pins. The voltage measuring circuit (52) includes a second multiplexing circuit (82, 84) and a voltmeter (86, 88, 90, 92). The second multiplexing circuit (82, 84) receives inputs from the various pins, as well as from opposite sides of the known resistance (R1, R2) in the current loop (50).      The second multiplexing circuit (82, 84) provides its output to the voltmeter (86, 88, 90, 92) for measurement. By measuring the voltage across the known resistance (R1, R2), and the voltage between the selected pair of pins, the resistance between the two pins can be derived.

IPC: G06F15/173
Filed: 1992-07-29
Abstract: Switch resources for a one-sided crosspoint switch with distributed control  (i.e.,  switch ports,  internal busses  and  controllers)  have  been  organized  so  that modular  growth  is  facilitated by:  (1)  assigning  each switch port uniquely  to  one  of  the  controllers;  (2) making  each  controller  handle  only  the  crosspoints connected  to  the  switch  ports  assigned  to  it;  (3) assigning  each  internal  bus  uniquely  to  one  of  the controllers;   and   (4)   providing  a  means  for  the controllers  to  communicate with  each  other.   Modular growth  of  any  of  the  switch  resources  (i.e.,  switch ports,    internal   busses   and/or   controllers)   is accommodated by effectively reallocating (i.e., modifying the assignment of) some or all of the resources.  Failure of a switch resource is accommodated also by effectively reallocating (i.e., modifying the assignment of) some or all   of   the   remaining  usable   resources.    It   is contemplated that modification of resource allocation can be done in various alternative ways, either physically or electronically,   including   automatically   and   even dynamically.

Title: Writing unit for a cartridge fountain pen
Inventor: MUTSCHLER OTTO
IPC: B43K5/18
Filed: 1991-01-15
Abstract: The invention concerns a writing unit for a cartridge fountain pen, with a nib (1), a gripping-piece (2) and an ink-feed unit (3).  The ink-feed unit (3) has lamella-like ink-holding chambers (3e). A capillary channel (3a) passes longitudinally along the whole length of the ink-feed unit (3) on the nib side of the ink-feed unit (3). An air channel (3c) extends out radially from the capillary channel (3a). So that ink does not drip out of the slit in the nib, particularly when the ambient temperature varies considerably, and to ensure that the ink-feed unit is suitable for broad-lettered writing, the writing unit is designed so that the air channel (3c) extends longitudinally over the whole length of the ink-holding chambers (3e) up to a control line (3g) which is formed at the end of the chambers (3e) nearest the nib (1) and which acts as a liquid valve. The air channel (3c) is delimited in the radial direction by a surface opposite the capillary channel (3a), and the air channel (3c) extends, on the side opposite the capillary channel (3a), up to overflow capillaries (3d) linked to the ink-holding chambers (3e) so that liquid can flow between the two.

Abstract: ABSTRACT          The invention relates to a method with which a preferably powder type preparation is measured out for an inhalation. The preparation for this is transferred from a reservoir to the correspondingly channelled inhalation flow produced by the patient on inhaling the product, such that the inhalation flow is swirled at the same time and the preparation is flushed out by the vortex into the current of air and is distributed in it.  The inhalation instrument with which the method is carried out has a dosing element (25) which is mounted so that it has limited movement, in an outlet hole (24) of a reservoir (21), such that a dosing recess (26) at the side, in one extreme position, is located inside the reservoir (21) and, in its other extreme position, is located in the inhalation channel (11).  The dosing element is actuated by the patient inhaling the product by way of an elastic element (30) or by way of a sealing cap for the mouth orifice (12) of the inhalation channel (11), whereby, with each movement of the dosing recess (26) from the reservoir (21) to the inhalation channel (11), one dose of the preparation is made available for inhalation.  The inhalation instrument has a vibration mechanism with which the powder preparation is held loosely and pourably.  Moreover, the inhalation instrument has a blocking mechanism (3) (which blocks the dosing operation if inhalation is not carried out with sufficient strength) and/or a dose-counting mechanism.
