Patent CA-2084841-C (CA)
Inventor: PELLEY KENNETH A
IPC: B05B15/04
Filed: 1992-12-08
Granted: 2004-07-13
Abstract: An apparatus and method for applying particulate powder material to a moving fibrous substrate is disclosed. The apparatus includes a volumetric dry material feeder for forming a continuous stream of particulate powder material. The continuous stream is then transmitted through a nozzle and exits at an outlet thereof. The nozzle is movable between a first and second position by a motion control. The motion control includes an adjustable differential gear box and an encoder for synchronizing the dispensing of powder at a predetermined location of the substrate. A flow separator is disposed beyond the outlet of the nozzle and intermediate of the first and second positions. In operation, the motion input drives the nozzle to oscillate between the first and second positions at a variable speed over each product cycle. As the nozzle crosses a plane of the flow separator, the continuous stream of particulate powder material exiting the nozzle is split into two intermittent streams of particulate powder material. The first intermittent stream is applied to a predetermined location of the moving fibrous substrate to form a layer of particulate powder material within a predetermined portion of the substrate. The second intermittent stream is recirculated back to the volumetric dry material feeder.

Title: Method and apparatus for fabrication of thin film semiconductor devices using non-planar, exposure beam lithography
Inventor: JACOBSEN STEPHEN C
IPC: G03F7/20
Filed: 1993-02-10
Granted: 1998-07-14
Abstract: An apparatus and method for the nonplanar treatment of  a  volumetric  workpiece  or  substrate  utilizing exposure beam lithography are disclosed.   The method includes supplying one or more layers of one or more semiconductor materials to surfaces of the substrate, applying a resist over the semiconductor layers, setting the resist, and then directing an exposure beam, such as an electron beam, toward the substrate.  The substrate is  then moved  in  at  least two  degrees  freedom  of movement,  relative to the beam,  with one degree of freedom of movement being the rotating of the substrate about an axis generally perpendicular to the beam.  The other degree of freedom of movement could be moving the substrate linearly in a direction generally parallel to the axis.  By such movement, the resist is exposed to the beam in a predetermined pattern.  The exposed resist is then developed and a  layer or  layers under the exposed resist are etched.  The remaining resist is then removed yielding the desired semiconductor device.

Title: Height adjustment mechanism for a chair seat back
Inventor: STUMPF WILLIAM S
IPC: A47C7/40
Filed: 1993-02-17
Granted: 1995-11-07
Abstract: An improved seat back height adjustment mechanism for a chair is disclosed.  The improved height adjustment mechanism includes a U-shaped mounting bracket having a back wall and two side walls.  A longitudinal cam having a handle is rotatably mounted in the bracket between the side walls and spaced from the back wall.  A seat back support arm is insertable through the bracket between the cam and the  bracket  back  wall.    The  cam  is  provided  with  a plurality of planar faces extending in the longitudinal direction   disposed   around   about   a   third   of   the circumference of the cam.  The radial length of the line extending perpendicularly from each planar face  to the longitudinal axis of the cam increases steadily from one planar  face  to  the  next  in  one  direction  around  the circumference of the cam.  This steady increase in distance of the planar faces from the axis of the cam provides a cam action on the seat back support arm when the cam is rotated in one direction with the support arm located between the cam  and  back  wall.    When  the  support  arm  has  been sufficiently compressed between the cam and back wall, one of the planar faces will be bearing against the surface of the support arm thereby forming a positive lock between the cam and support arm which prevents loosening of the cam due to rotation of the latter to the unlocked position.

Title: Door lock security system
Inventor: EKLUND SIGURD TORSTEN
IPC: E05B13/08
Filed: 1993-04-08
Granted: 1996-11-26
Abstract: A door security system is used in conjunction with a lock such as a deadbolt lock having an "inside" located actu-ating handle, of the type used in hotel rooms, having a major and a minor dimensional axis. The security device has a base-plate that fits beneath the faceplate of the lock and which can be oriented during installation in relation to the shaped actuating handle of the lock. The baseplate of the security device extends eccentrically off center and supports a pivot post that carries a latch locking plate. The locking plate is pivotally supported on the pivot post, for pivotal rotation thereabout, and has an arcuate passage-off-set from the pivot post, in use to receive the lock actuating handle. In use, with the baseplate installed beneath the faceplate of the lock and the lock handle rotated to extend the bolt, the locking plate may be rotated about the pivot post, swinging the arcu-ate passage over the lock handle in immobilizing relation therewith. In this condition the shaped lock handle cannot be rotated, and the lock is restrained in a locked condition de-spite the use of a proper key, externally.

Title: Single channel remote site trunking
Inventor: GRUBE GARY W
IPC: H04B7/26
Filed: 1992-07-24
Granted: 1998-07-07
Abstract: A system and method for providing single channel remote site trunking is described. The present invention allows for radios operating in single channel non-dedicated control channel sites (104) to communicate with radios in dedicated control channel sites (102) which are part of the system. Further, the present invention will allow for non-trunked radios to utilize the benefits of trunking when operating in the single channel remote site. By mapping the ID's of the radios in the system, the system can keep track of all radios in the system whether in a remote single site (104) or in one of the dedicated control channel sites (102) and thereby link radios in one site to automatically communicate with the radios in the other site.
Patent CA-2113284-C (CA)
Inventor: SOOD PRADEEP K
IPC: H02P6/18
Filed: 1994-01-12
Granted: 1998-06-16
Abstract: A dynamoelectric machine, for example, a brushless permanent magnet motor (M) has a plurality of stator windings (S) and a rotor (T) which rotates with respect to the windings.  Apparatus (10) is provided for controlling winding commutation with respect to the rotor.  A DC bus (14) supplies current to the windings.  The current waveshape has characteristics which are a function of the commutation angle with respect to the windings.  Current magnitude and waveshape are sensed by a sensing unit (22) and the sensed waveshape is sampled to obtain commutation information.  An inverter (20) successively energizes and de-energizes the respective stator windings.  A controller (26) obtains samples of the waveshape, and processes the information obtained by the sampling to control winding commutation.  The controller controls the inverter operation to provide a commutation angle which optimizes motor performance and efficiency for a particular set of motor operating conditions.  To do this, the processor evaluates slope and amplitude information from the sampled DC bus current waveshape, determines if the waveshape corresponds to a desired waveshape representing a desired commutation angle, and adjusts the commutation frequency produced by the inverter, if necessary, to obtain the desired waveshape.

Title: Dual product dispenser
Inventor: DUNNING WALTER B
IPC: B01F3/08
Filed: 1994-03-16
Granted: 2003-09-16
Abstract: A dispenser for simultaneously dispensing and mixing a pair of fluid products such as chemically reactive resins, from a pair of axial adjacent front and rear chambers. A piston is mounted within each of the chambers and is moveable with respect to the hollow interior of the respective chamber for dispensing the fluid product therefrom. Telescopic movement of the rear chamber within the front chamber moves the pistons synchronously through the chambers to provide for controlled discharge of the products through a front discharge nozzle. A fixed hollow delivery tube extends through the interior of the front chamber and telescopically receives therein a post which is mounted on a rear wall of the rear chamber. The rear chamber has a relatively tight sliding fit within the front chamber so that a partial vacuum is formed within an annular space which forms between the two pistons as they move apart upon discharge of the two products to produce a "suck back" effect on product remaining in the discharge nozzle.
