Patent CA-2066714-A1 (CA)
Inventor: WINTER JOHN M
IPC: H01H71/70
Filed: 1990-09-17
Abstract: Système de commande de disjoncteur (24) comprenant un ensemble fourche (36) entraîné par un moteur, actionné à distance, pour ouvrir en même temps tous les contacts de charge du disjoncteur (54) et les verrouiller en position ouverte. Une tension continue est sélectivement appliquée afin d'exciter le moteur CC réversible (32). Le contact (66) à l'endroit distant peut être actionné pour permettre au client/à l'utilisateur de réarmer le disjoncteur à l'endroit où ce dernier est situé. Cela est rendu possible grâce à un circuit à thyristor (70) qui est commandé à partir d'un contact à distance (66) et actionné par l'utilisateur pour inverser la marche du moteur et libérer les contacts du disjoncteur.

Patent CA-2070544-A1 (CA)
Title: Releasing linear actuator
Inventor: CULP GORDON W
IPC: F16D65/18
Filed: 1992-06-05
Abstract: ABSTRACT OF THE DISCLOSURE     The  present  invention  is  useful  for quickly releasing  an object which  is  being  moved  by  an  actuator.  Generally  actuators  of  the piezoelectric type move objects slowly. For applications where an object must  be  quickly moved  such as when  releasing  brakes  or reinserting a control  rod  in a reactor core an actuator should have a quick  release feature. The invention uses a set of actuators which contact a bolt and moves the bolt with smooth walking motion. The bolt in turn is driven by the actuators such that it engages an object with smooth walking motion to move  or  position  the  object.  When  the  object  is  to  be  released  the actuators are removed from contact from the bolt thereby releasing the object.

Title: Dispensing nozzle improvement for extracting fuel
Inventor: FINK ARTHUR C JR
IPC: B67D7/04
Filed: 1992-08-04
Abstract: Abstract of the Disclosure A fuel dispensing nozzle (10) has a body (12) including a fuel passage for fuel to flow from a source thereof through the body.  A spout (18) is attached to the body in fluid communication therewith for fuel to flow into the spout from the passage.  The distal end of the spout forms a mouth (19) insertable into the tank.  A vapor return path is provided for capturing fuel vapors and returning them to the source, so to substantially reduce or eliminate emissions.  A vacuum is produced in a variable venturi portion (42) of the nozzle and is applied to the return path to extract any fuel collecting therein.  This vacuum is in addition to another vacuum produced at the venturi and used to assist in automatically shutting -off fuel flow when the tank is full.  This device is a power generating source that is not limited to only fuel extraction and nozzle shut off.  It can also be used for other apparent uses, having the multiple usage applied in conjunction with the vapor recovery systems in the category of the balanced pressure system and the vacuum assist system.

Abstract: ABSTRACT OF THE DISCLOSURE           A method and multiple station flexible boring machine for transferring and locating a pallet carrying a workpiece to be machined. The machine has at least two machining stations and a part  loading and unloading station adjacent a transfer table carried by a base for carrying, generally locating and transferring a pallet and a workpiece to each station. The pallet has a curvic coupling locator ring with a plurality of circumferentially spaced and generally radially extending teeth for complementary mating engagement with a locator ring on an independent base of each station to accurately radially,  axially and circumferentially locate the pallet on the station base.  At the load station, the locator ring on the pallet is received in complementary mating engagement with the  locator ring on the load base accurately locating the pallet with respect to the base and a workpiece is loaded,  accurately located with respect to the  load base and clamped to the pallet. The transfer table generally locates and transfers the pallet from the load station onto the base of a first machining station accurately locating the workpiece for machining.          After at  least one machining operation  is performed at that station, the table transfers the pallet and workpiece onto the base of  the next machining station.  Upon completing all machining operations, the pallet and workpiece are returned to the part load station where the finished workpiece is released and removed and thereafter another workpiece to be machined is loaded, accurately located and clamped to the pallet.

Title: Imaging medium with bubble-suppressant layer
Inventor: LINDHOLM EDWARD P
IPC: B41M5/44
Filed: 1992-03-16
Abstract: An imaging medium (10) capable of being imaged to form a transparency comprises a substantially transparent support (12) having a thickness of at least 20 µm, a color-forming layer (16, 22, 26) superposed on the support and comprising a color-forming composition adapted to undergo a change of color upon increase in the temperature of the color-forming layer (16, 22, 26) above a color-forming temperature for a color-forming time; and a bubble-suppressant layer (32) superposed on the color-forming layer (16, 22, 26) and having a thickness of at least 10 µm.

Title: Support for plants and the like
Inventor: CHRISTIE MOLLY C
IPC: A01G9/02
Filed: 1993-05-25
Abstract: ABSTRACT     A support for plants, flowers and the like to assist horticulturists create novel arrangements. In one embodiment, the support includes framework surrounding an upstanding central tube. The framework consists of a plurality of vertically spaced, circular rings which decrease in diameter from bottom to top. Vertical supports span adjacent rings and are spaced about the circumference of the framework. A retaining ring surrounds the bottom of the tube adjacent its bottom and has two pair of diametrically extending arms with downturned ends to support the tube in an upright manner. A second retaining ring surrounds the tube adjacent the top of the framework. The downturned ends of this retaining ring snap over the top of the framework to hold the framework and tube in place. Matting lines the interior of the framework to define an enclosure to be filled with soil. Plants, flowers and the like can be planted in the soil through the matting. The framework can be placed in an existing flower pot or can stand alone. Accessories of various shapes such as a sphere can be attached to the top of the tube above the framework to increase the variety of arrangements that can be created. In a second embodiment, the upstanding central tube is removed and the framework is used only in conjunction with the matting. In yet another embodiment, the matting is replaced with moisture retaining material to allow cut flower arrangements to be created.

IPC: H01J49/04
Filed: 1993-07-05
Abstract: TITLE: Electrospray Interface for Mass Spectrometer INVENTORS: Michael G. Ikonomou and Paul Kebarle ABSTRACT OF THE DISCLOSURE A novel electrospray interface provides high sensitivity   and   signal   stability   for   mass spectrometric detection of analytes in solvents with high  water  content  including  100%  water.    The electrospray capillary tip section is heated close to the boiling point of the solvent.  An approximately 20°C hotter airstream is also used.   Its flow is coaxial and codirectional to the electrospray.  With this arrangement, the analyte signal sensitivity and stability obtained with neat water is equal to that with neat methanol.   The charged state (degree of protonation) of protonated peptides sprayed from neat water and the heated spray is essentially identical to that observed with unheated spray where the solvent was 80% methanol - 20% water.

Filed: 1993-03-05
Abstract: Self supporting rubbery flow blocking devices (1) of substantial thickness is mounted in a fluid passageway to automatically regulate fluid flow control where the incoming volume of water fluctuates to retain maximum fluid levels for either storage or gravitational potential energy and prevent undesirable flooding upstream of the dam. The rubbery elastomeric components (1) have one edge free and one edge firmly secured to a supporting surface (6) and anchored thereto by members (3, 4), the components have elastic internal resistance elements (2) so placed as to increase elastic resistance to flexing along their length from their free ends to their secured ends. The components will remain in a blocking position to fluid flow while subjected to pressure up to a given design pressure, and are pliant enough to flex away from the fluid pressure to unblock part of the fluid flow when subjected to a fluid pressure greater than the design fluid pressure.
