Patent CA-2062113-A1 (CA)
Title: Optical printing system with discontinuous print medium
Inventor: FERLA GUILLERMO S
IPC: B41J2/52
Filed: 1992-03-02
Abstract: ABSTRACT OF THE DISCLOSURE A printing system employs a rotating drum for carrying a photosensitive printing medium in the form of a discontinuous sheet, there being a clamp carried by the drum and rotating therewith for holding ends of the sheet to secure the sheet to the drum. The system includes a print head having a laser beam which is spatially and temporally modulated for gray-scale printing of individual pixels of an image. The head is scanned parallel to an axis of the drum. A servomechanism responsive to angular orientation of the drum produces a linear scan during rotation of the drum. An optical system within the head provides a common path through a common objective lens for both a write laser beam and for a focus laser beam of an automatic focusing apparatus which positions the objective tens rapidly by a dither motion to compensate for undulations in the surface of the print medium. The objective lens is carried at a reference position during passage of the clamp, the reference position being updated periodically by measurements of focus.

Title: Pivotal gate trap for birdhouse
Inventor: FINN JOSEPH
IPC: A01K31/10
Filed: 1992-10-14
Abstract: ABSTRACT OF THE DISCLOSURE   A trap for a birdhouse, the moving parts of which are attachably and detachably integrated with bearing, aligning, and attaching features which are permanently part of the birdhouse entry hole panel, achieving reduction of trap structure and greater convenience of use. A pivoting gate is set above the entry hole within the birdhouse, and is retained there by a trip assembly. A bird entering the birdhouse, and alighting on the trigger extension of the rotatable trip assembly, causes the trip assembly to disengage from the free end of the pivoting gate, which falls, blocking the entry hole and trapping the bird within. The trap includes structure to facilitate removal of the trapped bird. The trap has structure to allow an option of sensitive or stable trap settings.

Title: Automatic optimization of photographic exposure parameters through determination and utilization of extra system speed
Inventor: O'SUCH WILLIAM R
IPC: G03B7/08
Filed: 1991-08-22
Abstract: Exposure control apparatus and methods for use in a photographic camera to improve the overall quality of photographed images using automatic selection of photographic exposure parameters primarily based upon scene requirements (including providing sufficient depth-of-field and avoiding image blur) and film exposure characteristics, rather than through use of the ISO/ANSI exposure standards. Specifically, the present invention: (a) determines the initial baseline exposure settings necessary to provide typical ISO  normal exposures of scenes to be photographed; (b) ascertains corresponding exposure settings (and, where appropriate, flash parameters) that actually meet the scene requirements; (c) assesses the amount of available extra system speed based on differences between the initial and corresponding exposure settings; and (d) finally, where possible, properly utilizes that extra system speed in a pre-defined prioritized incremental manner to vary the baseline exposure settings (and, where appropriate, flash parameters) in order to provide an exposure of the scene that produces the desired level of image quality.

Abstract: Implantable therapy systems are disclosed for the local and controlled delivery of a biologically active factor to the brain, spinal cord and other target regions of a subject suffering from a dibilatating condition. The method of the invention involves surgically exposing an insertion site, generally located above a predetermined treatment site (12), in a patient. A cannula (20), having an obturator (30) positioned therein, is inserted at the insertion site, defining a pathway to the treatment site. The cannula (20) is preferably a low friction polymeric material such as polytetrafluoroethylene. The cannula (20) generally has an open proximal end for receiving the obturator (30), and an open distal end, preferably a tapered end, for delivery of neurologically active factors to the treatment site (17). The obturator (30) is then removed from the cannula (20), and a biocompatible tethered vehicle (40) containing a biologically active material is inserted into the cannula along the passageway. A guide wire (32) can be inserted within the cannula, behind the vehicle (40), to position the proximal end of the vehicle at the proximal tip of the cannula (20b). Once the vehicle (40) is positioned near the proximal end of the cannula (20), the cannula is removed from the passageway, followed by the guide wire (32), leaving the vehicle (40) positioned at the treatment site (12);

Abstract: A compressor oiling system for a horizontal rotary compressor including a pressure plate defining a motor chamber and compressor unit chamber within the compressor each having an oil sump.  An opening in the pressure plate allows oil pressurized by discharge pressure from the compressor to pass through an oil pickup passageway leading from the sump portion of the compressor unit chamber to the outboard bearing of the actual compressor unit.  During compressor operation, discharge gases create a pressure differential across the pressure plate allowing the oil level to raise within the compressor unit chamber to the level of the crankshaft thereby lubricating the crankshaft bearings.

Abstract: A mixing apparatus for mixing two or more fluids into a homogeneous mixture.  A rotor (62) is mounted on a drive shaft (56) coaxially within a cylindrical casing (2).  Bores (88) run the length of the rotor.  Mixing conduits (90) lead from the bores (88) to outside the rotor (62). A cylindrical sleeve (42) with slots (92) is mounted coaxially within the casing (2) and encloses the rotor (62). The fluids to be mixed are introduced into one end of the casing (2) within the sleeve (42) while the rotor (62) is rotating. The fluids are sheared as they enter into the bores.  The combined fluid either passes out of the mixing conduits (90) near the front of the casing where it is sheared again or passes further along the bore to exit mixing conduits (90) near the rear of the casing. The fluid then passes through the slots (92) in the sleeve (42), where it is sheared again.  Finally, the mixed fluid exits the other end of the casing.

Abstract: An interactive electronic thermostat incorporates a safety backup system to automatically activate the HVAC system in the event that normal operation of the thermostat is interrupted and the temperature in the conditioned area falls or rises beyond a predetermined range. The thermostat operates to communicate with an installer through an audible or visual display and keypad to instruct the installer to perform tasks and enter observations to effect proper connections at the thermostat of HVAC system wires even in the absence of labels identifying the functions of those wires. The thermostat requires entry of coded indicia representing operator-observed conditions in the system in response to displayed instructions carried out by the operator.
