Title: Method and apparatus for preserving masonry structures
Inventor: WYNER JAY S
IPC: C04B41/45
Filed: 1990-06-05
Granted: 1995-07-04
Abstract: A method and apparatus for preserving masonry structures having embedded structural or reinforcing steel rods by applying a liquid preser-vation material to the surface of the structure and injecting the material into the structure using the blasting force of compressed air.  Separate mani-folds having outlet nozzles are provided for the air and for the liquid.  The manifolds and their nozzles are arranged so that, as the liquid is applied to the surface of the structure, the air injects it into the interior of the structure to coat the reinforcing steel and the surfaces of the interstices of the masonry granules of the structure.  The air acts as a fluid hammer.  The preservation taking place is without the need of disturbing, breaking open or repairing the concrete, brick or masonry granular surfaces.

IPC: H04N5/208
Filed: 1991-07-18
Granted: 1995-12-05
Abstract: A black compensation circuit for compensating a luminance signal which is subjected to edge enhancement, comprises: a black-level expanding circuit responsive to a control signal and the luminance signal for performing expansion of a tone of a black portion of the luminance signal and for performing conversion of the luminance signal into a black-level expanded signal in the absence of the control signal; a low-pass filter circuit for low-pass filtering the luminance signal to remove high frequency components; a detection circuit responsive to an output of the low-pass filter circuit for detecting the blackest level for a given interval; and a comparing circuit for comparing the blackest level with a given level to produce the control signal, thereby the black-level expanding circuit stopping the expansion and the conversion in the presence of the control signal.  The blackest level does not change with sharpness because after the luminance signal subjected to edge enhancement is passed through the low-pass filter, it is sent to the detection circuit.  An input signal of the low-pass filter may be supplied from the black-level expanding circuit.

Title: Bicycle boat
Inventor: CHASE NOEL EDMONDS
IPC: B63H21/175
Filed: 1992-05-26
Granted: 1999-10-12
Abstract: Many human powered boats have been developed, including designs with rigid hulls and paddle wheels or screw pro-pellers, bicycle-type frames on rigid and inflatable pontoons, and flotation wheels on a bicycle frame. Ultimately, a reclining bicycle frame mounted on hydrofoils, supplemented with pontoons and using an air screw propeller is the design that currently holds the human-powered speed record on water.      This invention addresses the failings of a type of human powered boat which allows a conventional bicycle to be supported on and used to drive a collapsible boat. The entire boat can be stowed on the rack above the rear wheel.      It has two inflatable pontoons and a light, collapsible frame. The rear wheel rides on a split roller which, through a series of miter gears, drives a screw propeller. The front wheel is connected to a hinging swivel which in turn is connected to the forward rudder and/or propeller housing.    This invention allows the user to bicycle to a lake, inflate and assemble the boat, boat across the lake, disassemble and stow the boat and continue bicycling again.      Additional features, such as a reverse drive, combined forward and rear steering, and hinging couplings on the forward rudder and rear drive assemblies to minimize damage from submerged logs are included in this invention. Finally, a series of performance boats with rigid hulls and with the same forward rudder and/or rear drive assemblies are shown.      While this application is primarily about human powered boats, the configuration of a motorcycle is essentially the same as a bicycle. Many of the features disclosed could apply to a motorcycle boat, albeit necessarily stronger to support the additional weight of the motorcycle.
