Abstract: A source for a linear homodyne transceiver that generates repeated linear chirps. A YIG oscillator with a main coil and an FM coil receives a basic linear current ramp at the main coil to generate a chirp. The FM coil is coupled to receive a PLL error signal. The PLL receives a sample of the output signal from the YIG oscillator at one input and a linear chirp reference signal at the other input generated by a DDS chirp generator. Any variation between the linear chirp frequency at any instant and the actual frequency output by the YIG is corrected by an error signal to the FM coil to correct for nonlinearities of the YIG caused by variations in the chirp rate, the rate of change of frequency per second per chirp, temperature variations and microphonics.

The disc is somewhat flexible and has a sealing surface on one side for proper seating and sealing on the container lip.
Abstract: A method for training an animal capable of learning to associate a consistent positive audio tone with pleasant feelings. The method includes a consistent positive audio tone capable of being sensed by the animal without startling the animal, and a consistent negative audio tone distinct from the positive audio tone capable of being sensed by the animal and startling the animal. The invention enables a trainer to encourage good behavior by the animal by applying the positive audio tone after the animal has been trained to associate the positive audio tone with pleasant feelings, and to discourage bad behavior by the animal by applying the negative audio tone.
Abstract: An improved evacuation pump system uniquely designed to evacuate both lidded rigid containers and sealable flexible containers. A vacuum cup fixed to one end of a reciprocating piston pump attaches to the lid of rigid containers for their evacuation and a flexible probe connects to the pump for flexible container evacuation. To achieve this dual function a inlet passage in the pump has a cross bore that slidably and/or rotatably receives a two position valve that selectively connects the pumping chamber with two outlets, one associated with each mode. The flexible probe connects directly to this valve reducing the need for separate passageways.
Abstract: A skate and skate brake which allows a user to brake the skate smoothly and evenly without catching on a ground surface utilizes a rotatable assembly having a resilient outer circumferential member attached to a relatively hard inner hub, the rotatable assembly brakes the skate by rotating with a rotational friction greater than that of the average rotational friction of the skate wheels. The rotational friction of the rotatable assembly is controlled by locating a non-rotating brake pad in physical contact with the inner hub. The amount of rotational friction can be increase by urging the brake pads against an annular portion of the inner hub and by positioning the brake pads within an interior recess inside the inner hub so that an increase in the downward force that the user applies to the brake increases the force by which the inner hub of the rotatable assembly is urged against the brake pads.
Abstract: An improved evacuation pump system with dual inlet check valves uniquely designed to evacuate both lidded rigid containers and sealable flexible containers. A vacuum cup fixed to one end of a reciprocating piston pump attaches to the lid of rigid containers for their evacuation and a flexible probe connects to the pump for flexible container evacuation. To achieve this dual function two check valves mounted in the lower end of the pump are provided for the flexible container evacuation mode. One prevents discharge flow into the flexible probe and the other maintains suction in the cup to keep the pump attached to its supporting surface.
Abstract: A method for assisting a lottery player to rapidly and accurately identify winning lottery games which includes the use of a playing card where selected numbers from each game is circled in a row containing all the possible numbers for that game with the rows arranged in columns so that each column contains identical numbers. When the winning numbers are drawn they are indicated on the playing card by drawing a line down the column where the number occurs and the readily observable intersection between the drawn line and the encircled selected numbers indicate winning games when the selected numbers and winning numbers intersect in a winning number of instances.
