Patent CA-2197151-C (CA)
Inventor: BALLARINO OTTAVIO
IPC: A01G17/06
Filed: 1997-02-10
Granted: 2005-01-04
Abstract: This invention relates to an improved plant holder for use in a garden for supporting plants and vines as they grow and mature. The plant holder comprises a plurality of identical posts which may be driven into the ground by means of pointed ends. Each post has a plurality of hooks in pairs at different heights along the post. Further, between the posts rods are provided that clip into the hooks to lie in a horizontal plane at each of the different levels of the hooks. Since the hooks are paired on either side of the posts at different levels then a pair of rods may also be found at the corresponding levels. Each pair of rods is connected by C-clips which snap over the rods. A plant, such as a tomato plant, may be supported by this structure by driving the posts on either side of the plant, assembling the rods into the hooks on either sides of the plant stems, then applying the clips to secure the rods into position. Further, the clips are sufficiently spaced on the rods allowing a branch of the plant to be drawn through an opening in the clips for further support of the branches.

Title: Aerated storage bin for crop materials
Inventor: EYDELNANT BORIS F
IPC: E04H7/26
Filed: 1997-04-23
Granted: 2006-01-10
Abstract: An aeration bin for storing crop materials comprises a circular concrete pad with a bin wall attached to the pad around the outside edge so as to stand upwardly therefrom and contain crop material inside the bin wall and on top of the pad. An aeration pit covered by a perforated planking floor is provided in the concrete pad and communicates through a duct through the concrete pad to a fan outside the bin for transmission of aeration air through the pit and upwardly through the floor into the crop material. The pit is of circular shape in plan view so that the concrete pad surrounding the pit is annular. This has the advantage of maximizing the floor area available for the pit, avoiding sharp edges where cracks can occur and allows a simpler leveling of the annular concrete pad during laying of the pad.

Inventor: PELZ DIETER
IPC: H01P1/205
Filed: 1997-06-30
Granted: 2000-08-15
Abstract: An arrangement for adjustably coupling a radio frequency input port to a resonator element of the filter. The arrangement comprises a resilient conductor (19) which extends from the input port (15) into the electric field of a resonator element (2). The remote end of the resilient conductor resiliently abuts the point (20) of an adjustment screw (20a). Operating the screw moves the resilient conductor in relation to the electric field and alters the capacitive coupling between the input port and the resonator element for fine tuning the impedance match of the input to the filter.

Title: Survey apparatus and methods for directional wellbore wireline surveying
Inventor: UTTECHT GARY
IPC: E21B47/022
Filed: 1997-07-04
Granted: 2005-02-15
Abstract: A wellbore survey method and apparatus which includes a gyroscope, wherein the gyroscope has a spin axis, aligned with the instrument axis, and further having two sensitive axis orthogonally related to the spin axis and to each other. In addition, the wellbore survey apparatus contains a drive means, functionally connected with the gyroscope, to rotate the gyro about the instrument axis.

Title: Adhesion promoters for anionic bituminous emulsions
Inventor: SCHILLING PETER
IPC: C08L61/32
Filed: 1997-09-09
Granted: 2002-07-30
Abstract: This invention relates to rapid set, medium set, and slow set anionic emulsions prepared from straight bitumen or bitumen modified by the incorporation of polymers such as  styrene  butadiene  rubbers   (SBR),   styrene  block copolymers (SBS), ethylene vinyl acetate copolymers (EVA), and other suitable modifiers.  The invention also relates to emulsions modified by the incorporation of solvents (such as diesel oil or kerosene) or by the addition of polymer  latices  (such  as  SBR-latex  or  natural  rubber latex).    More  particularly,  the  invention  relates  to improved methods for enhancing adhesion between asphalt and aggregate in anionic solventless and solvent-containing bituminous emulsions wherein the emulsifiers are alkali earth salts of tall oil fatty acids, fortified tall oil fatty acids, tall oil rosin and fortified rosin as well as combinations of kraft lignin and nonionic emulsifiers.  The novel adhesion promoters utilized in these improved methods are the polyamidoamine condensation reaction products of polyalkylene polyamines with monomeric tall oil fatty acids and polymerized linoleic acids.   Further improvement in adhesion can be obtained via adding paraformaldehyde to the reaction.

Abstract: A transition support is provided herein for extending over a low area of a floor and for extending under a flooring material where the floor has a high area at a relatively high height adjacent to the low area at a relatively low height, with a juncture between the high area and the low area. There is a difference in the heights between the high area and the low area of the floor. The transition support comprises an elongate wedge in sheet form, the elongated wedge having equal top surface and bottom surface. The transition support includes a relatively thick end having a thickness between the top surface and the bottom surface of the support, the thickness being generally equal to the difference in the heights between the high area of the floor and the low area of the floor, the relatively thick end being placeable in the juncture adjacent to the high area of the floor. The transition support further includes a relatively thin end opposite to the relatively thick end and parallel to the relatively thick end. The relatively thin end is placeable on the low area of the floor which is remote from the high area of the floor and the juncture. The transition support further includes a tapering section extending along the top surface and defining a support surface for being covered with the flooring material. The distance between the relatively thick end and the relatively thin end being at least 30 times the thickness of the relatively thick end. This renders the junction generally unnoticeable to persons walking across the flooring material on the tapering section and for generally preventing the jostling of wheeled vehicles crossing the flooring material on the tapering section.

Title: Automatic gain control for free-space optical telecommunications links
Inventor: JAVITT JOEL I
IPC: H04B10/118
Filed: 1998-02-12
Granted: 2002-01-29
Abstract: Free-space optical transmission of analog information is facilitated by transmitting constant-amplitude pilot information with the other information. The amount of attenuation of the pilot information at the receiver is detected and used to control the amount by which received information is amplified. In this way the deleterious effects of free-space optical attenuation are substantially eliminated. The pilot information may be transmitted either via its own separate light frequency or wavelength, or as a distinguishable part of a larger quantity of information that is used to modulate one light frequency or wavelength.
