Title: Lighted slip bobber fishing apparatus
Inventor: JOHNSON BRYAN L
IPC: A01K93/02
Filed: 1992-06-03
Granted: 1996-01-30
Abstract: The present invention provides a fishing apparatus of a type that secures to a fishing line having a remote end.  A float member is slideably secured relative to the fishing line, and a depth signaling means is operatively connected to the float member.  A stopping means is operatively connected to the fishing line at a predetermined distance from the remote end to prevent the float member from sliding beyond the predetermined distance from the remote end of the fishing line.  Thus, the stopping means effectively establishes a maximum depth to which the remote end may descend when the float member is afloat.  The depth signaling means signals when the float member has slid the predetermined distance from the remote end of the fishing line, and hence, when the remote end has descended to the predetermined maximum depth.

Title: High-frequency power amplifier
Inventor: SEKINE KENJI
IPC: H03F1/02
Filed: 1992-07-17
Granted: 1996-06-04
Abstract: A high-frequency power amplifier comprises a pair of FETs, a divider for supplying to the FETs opposite-phase versions of a signal to be amplified, distributed-parameter transmission lines respectively connected at first ends thereof to output electrodes of the FETs.  A combiner combines signals appearing at other ends of the transmission lines into a signal with a common phase. Stubs which short-circuit for even harmonics in the output signals of the FETs are connected to the respective transmission lines at positions distant from the output electrodes of the FETs by a multiple of a quarter wavelength of the fundamental wave. A first capacitor is connected between the transmission lines at positions distant from the output electrodes of the FETs by a 1/12 wavelength of the fundamental wave so that the output electrodes of the FETs are open for the third harmonic.  A second capacitor is connected between the transmission lines at positions between the connecting positions of the first capacitor and the connecting positions of the stubs to the transmission lines so as to perform impedance matching for the fundamental wave.

Patent CA-2115939-C (CA)
Inventor: ATKINS ROBERT MICHAEL
IPC: C03B37/12
Filed: 1994-02-18
Granted: 2000-05-16
Abstract: Described is a new method and apparatus for measuring the thickness of a thin conductive coating deposited on a moving elongated dielectric body. Of special use is an application of a carbon coating on an optical fiber. The conductive coating is measured by establishing an electromagnetic field in a resonator including an elongated unshielded helix and a pair of coupling loops. The helix is suspended between the coupling loops out of contact with either one of them. An electromagnetic energy is coupled into one loop as an input signal from a source of electromagnetic energy and coupled out from the other loop as an output signal. The difference between the magnitude of energy of an empty helix or with an uncoated body, and the helix with a coated body, is used for controlling the coating process. The inner diameter of the helix is large relative to the diameter of the elongated body being at least five times the diameter of the fiber and the spacing between the coils of the helix being equal to the cross-sectional dimension of the rod, wire or tubing making up the coil. The general principles stated herein can be applied over a wide range of radio frequencies, typically from about 100 MHz to 100 GHz, and can be applied to a wide range of coating configurations by appropriately selecting a frequency range and equipment that is compatible with the selected frequency range.

Title: Growth medium for plants
Inventor: FLOYD JAMES
IPC: C05G3/80
Filed: 1994-11-08
Granted: 2004-05-11
Abstract: A growth medium for a plant having roots comprises an upper compression resistant layer and a lower root development layer. The upper compression resistant layer comprises a compression resistant mixture of discrete inorganic particles and solid rubber particles.      The thickness and the amount of the solid rubber particles is sufficient to substantially absorb compressive loads which are applied to the top surface of the compression resistant layer. The compression resistant mixture has sufficient porosity to permit water to drain therethrough.      The lower root development layer comprises a mixture of discrete. inorganic particles and organic material. The size of the discrete inorganic materials and the amount of organic matter are selected to allow the capillary flow of water in the mixture of discrete inorganic particles and organic material. The organic material has a size sufficiently large to remain in the mixture against the leaching action of water passing through the root development layer. The distance between the top surface of the growth medium and the lower root development layer is sufficiently small to enable the roots of a plant to reach the lower root development layer.

Abstract: An anti-icing fluid suitable for ground treatment of aircraft, being a glycol-based, aqueous solution containing a hydrophobe-bearing, macromonomer-containing polymer thickener in an amount of less than about 5 weight %. Thickening occurs predominantly by association among hydrophobe groups. Thickening may be enhanced by addition of a surfactant or other materials which act as co-thickeners. Use of this thickened fluid does not adversely affect airfoil lift characteristics during takeoff, because the fluid exhibits shear thinning and readily flows off the aircraft surfaces when exposed to wind shear during the air-craft's takeoff run.
