Title: Baffle assembly for a seed metering mechanism
Inventor: OLSON THOMAS A
IPC: A01C7/12
Filed: 1997-08-19
Abstract: A baffle assembly for a seed metering mechanism that is mounted in combination with a seed hopper holding a supply of seeds that are to be dispensed into a furrow with regularity by the seed metering mechanism.  The seed metering mechanism includes a two-piece housing divided into a seed chamber and a vacuum chamber by a rotatable disc having a series of throughopenings or holes arranged circumferentially adjacent the perimeter of the disc.  The disc picks up seeds from the seed chamber and carries them around to a discharge area of the seed metering mechanism whereat they are released for gravitational deposit into the furrow in the ground below.  A seed delivery chute gravitationally directs the seeds from the seed hopper to an opening defined by the housing from which the seeds are deposited into the seed chamber. A salient feature of the present invention relates to the provision of a baffle assembly for controlling from outside of the housing the amount of seeds passing through said opening and passing into the seed chamber while maintaining the housing in assembled relation.
Patent CA-2214228-A1 (CA)
Inventor: GANSEL CHRISTOPHER L
IPC: F23D11/44
Filed: 1997-08-27
Abstract: A fuel control and preheating module for use with an oil-burning furnace including a fuel line providing a passageway  section  through  which  oil  is  routed  from  a reservoir to the furnace for burning includes an electrically-powered positive temperature coefficient (PTC) heating element mounted in heat transfer relationship with oil contained with the passageway section.  During the operation of the PTC element, the PTC element heats the oil contained within the passageway section to a preselected temperature and maintains the oil  contained within the passageway  section at the preselected temperature.  Also associated with the module is a movable diaphragm and shutoff plate which is responsive to the internal pressure changes in the air passageway of the furnace upon shutdown and start-up of the furnace to withdraw oil from and shut off delivery of oil to the nozzle upon furnace shutdown and to push oil toward the nozzle upon start-up of the furnace.

Title: Reconstruction system and methods for impedance imaging
Inventor: MU ZHEN
IPC: A61B5/053
Filed: 1997-10-02
Abstract: A method of imaging an object contained in a medium, having a specific impedance which is different from the specific impedance of the medium, comprising applying current to the medium at various locations at a surface of the medium, extracting current at other locations, detecting voltages produced by the current which has passed through the medium from the surface of the medium at various other locations, successively determining a location and shape and conductivity of the object with increasing accuracy by processing values of the detected voltages, determining a region in the medium in which the object is located from values of the detected voltages which are within upper and  lower threshold values, applying acceleration procedures to the conductivities within the region in the course of iterative refinement of these values in the course of an imaging procedure, subsequently restricting further determination of the location of the object with increasing accuracy to voltages obtained from the region of the medium in which the object is located, and displaying an image on an axis using the restricted location determination values.

Inventor: LUPKE MANFRED A A
IPC: B29C49/00
Filed: 1997-10-21
Abstract: The present invention provides an apparatus for forming a profiled pipe in which the apparatus includes a plastic extruder extruding plastic to the forward end of a mold tunnel formed by mold blocks having shaped inner faces which determine the particular profile of the pipe. A negative pressure region is provided within the mold tunnel slightly downstream of its forward end where vacuum from the negative pressure forces the flowing plastic on to the inner faces of the mold blocks. Also provided is a reservoir at the forward end of the mold tunnel. The reservoir provides a region through which the plastic is moved smoothly from the extruder to the negative pressure region of the mold tunnel where the plastic is then transferred from the reservoir evenly onto the mold block faces.

Title: Arrangement for installing glass ceramic cooking surfaces in an edge area that tapers to a thin edge at a sill plate
Inventor: WEISS EVELIN
IPC: F24C15/10
Filed: 1997-11-27
Abstract: As part of the kitchen fixtures, glass ceramic cooking surfaces are subject to fashionable design trends.   The market thus now calls for glass ceramic cooking surfaces with a circumferential flat polished bevel.   These glass ceramic cooking surfaces are especially sensitive to shock and thus to breakage at their edges.          The invention provides for special edge protection, which protects the thin edge of the glass ceramic cooking surface from direct mechanical shock stress from the side and/or from above.  A basic embodiment with circumferential edge protection that consists of a permanently elastic layer, which encases the front of the edge and its lower side and which is formed from a frame that is made of hard material, is suitable for installation on a sill plate.  In the case of another basic embodiment for installation in a cutout in the sill plate, the glass ceramic cooking surface, which is provided with the permanently elastic layer on the lower side and a supporting frame that is attached to it, is installed recessed in the cutout, whereby the encasing of the front with the permanently elastic layer is done in the installed state.

Title: Dual size cup carrier
Inventor: SLOMSKI EDWARD J
IPC: B65D71/50
Filed: 1997-11-28
Abstract: The cup carrier of this invention comprises a sheet of flat flexible material which forms at least one cup receiving opening and a handle. Each cup receiving opening is surrounded by a cup engaging portion that engages a tapered sidewall of a cup when the cup is inserted within the cup receiving opening. The cup engaging portion of the sheet forms an inner ring and an outer ring and bands connect the inner ring to the outer ring. A generally radial slit is positioned, preferably at an approximate midpoint, between two adjacent bands. The cup carrier permits a user to insert cups having a range of diameters into the cup receiving openings. A user can insert a small cup within the cup receiving opening and engage a sidewall of the small cup with the inner ring of the cup engaging portion. A user may alternatively insert a large cup within the cup receiving opening after breaking the inner ring along each of the generally radial slits, and engage a sidewall of the large cup with the outer ring of the cup engaging portion.

Abstract: A process for preventing or retarding frost formation on substrates such as grass or leafy plants is disclosed. The process involves spraying the surfaces of these substrates with a frost prevention composition comprising a mixture of water, a water-soluble freezing point depressant, such as propylene glycol, and a water dispersible thickening agent for such composition, such as a cross-linked polyacrylic acid polymer. The composition is preferably applied just prior to expected frost onset and serves to lower the freezing point of dew which accumulates on such substrates which have the frost-prevention composition adhered to the substrate surfaces.
