Patent CA-2146066-A1 (CA)
Title: Trim retainer
Inventor: WINKELHAKE WILLIAM
IPC: F21S8/02
Filed: 1995-03-31
Abstract: This invention relates to an improved lighting fixture of the type which may use a trim-ring connected to the bottom of a lighting fixture housing can and is applicable to lighting fixtures of either the recessed variety or of the track variety.  In most of such housings, portions of the sheet metal walls are punched out and deflected inwardly forming lugs, or auxiliary brackets are welded to the inside of the housing, to support such baffles, trim-ring means or other assembly means.  Such lugs, or brackets, generally have extremely sharp burr edges.  The means used for fastening the trim rings or other means to such lugs generally are well known and are usually either torsion springs or tension springs.          In each instance, it is necessary for the installer to insert his hands into the interior of the can to install the secondary retaining spring members and thereby expose his hands to the sharp burrs on the edges of the sheet metal lugs used to support the retaining spring members.  The present invention provides an improved trim-ring and baffle mounting system for a simplified assembly and retention system for aesthetic auxiliary items.  There is provided an internal support system for the housing of a can-type lighting fixture that is simple in construction and can be assembled rapidly at the point of installation.  This can be adjusted axially to a plurality of positions in a simple and effective manner without the use of external fastening means such as screws and without the problem of confronting sharp burr-like edges of sheet metal projecting into the interior of the can-like housing.

Patent CA-2156002-A1 (CA)
Inventor: AKINPELU AKINWALE ADEMOLA
IPC: H04Q3/08
Filed: 1995-08-14
Abstract: In an environment of competitive local and interexchange carriers, offering number portability between local carriers serving a common region and between switches serving that region, each local carrier accesses a regional database to determine the identity of the carrier and switch serving a local customer. Inaddition, interexchange carriers access a national database to determine the identity of the carrier and switch serving the customer specified by the number dialed by an originating customer.  For customers requiring high reliability service, alternate carriers can be used to serve such customers in case the primary carrier is unavailable; the databases identify these alternate carriers.  Advantageously, this arrangement allows a high degree of freedom of movement of customers between carriers and geographic relocation without requiring a number change.

Title: Expansion shelf for access system and switch block therefor
Inventor: GINGELL MICHAEL JOHN
IPC: H04Q11/04
Filed: 1995-09-21
Abstract: A cross-connect for interfacing high-speed ports and having add/drop multiplexing capabilities for permitting simultaneous access to all individual subscribers may be improved by utilizing a switch block arrangement for allowing downstream subscribers to be switched among each other without the need to be switched upstream through the cross-connect or may alternatively be improved by substituting an expansion shelf in place of a line shelf so as to permit the addition of additional line shelves and hence, additional subscribers.  This latter improvement is made possible by assuming that not all subscribers will need access to the cross-connect at the same time.  A switch block for such arrangements can output either an input data signal previously stored in a switch memory or a daisy-chain input that is output from another switch block in the arrangement.

In the preferred embodiments, the cutting instrument is a pair of scissors with the blades disposed within the chamber but operable from without the chamber.  In all embodiments, the instrument is a pair of scissors with the cutting blades extending into the chamber through a rear opening while the levers for operating the blades remain outside the chamber for manual manipulation by an operator's hand.  In the first through third embodiments, the cutting chamber outlet is also an elongated, preferably curved, handle disposed above the cutting instrument.  In the fourth and fifth embodiments, the levers of the cutting instruments are offset from their respective blades to allow the chamber outlet to be disposed below the levers.  Also, a wide variety of spacers, some angled, are selectively attached to the inlets of all the embodiments to regulate the length and taper to which hair is cut.

Abstract: An actuator for precisely moving and positioning a manufacturing component  includes a housing on which a magnet is mounted. An electromagnetic is slidingly mounted on the housing for movement within the magnetic field generated by the magnet.  A rod,  having  a member  for gripping  the  component,  is  attached  for  translational movement with the electromagnetic coil. In the operation of the actuator,  a current is selectively applied to the electromagnetic coil. The current in the coil creates a magnetic field that moves the electromagnetic coil and the attached grip within the magnetic field to position the component as desired in translation. A retractor causes the grip to preferentially adopt a predetermined position, or dwell configuration.
