Abstract: A spacer system for attachment to a sprinkler to prevent the positioning of the sprinkler too close to a sidewalk or curb, etc., including a spacer which can be attached to the sprinkler, and an elongated stake having a notch for receiving and holding the spacer. Also described is a tool for use in installing the stake in the ground.

Abstract: A computerized exercise cycle is disclosed. The exercise cycle presents an exercise structure having a pair of pedals operable by a user against resistance provided by an adjustable resistance means. The resistance means is controlled by a computer which can be programmed by a user in a user-selected program of intensities to thus vary the resistance intensity over a programmed time duration. The exercise cycle is programmed to display an imaginary speed, a relative resistance level, a time counter or a countdown from a set time, a distance traveled, or a countdown from a set distance, and revolutions per minute. The computer also allows the user to select a target pulse value. The computer automatically adjusts the resistance to cause the user's pulse to approach the selected target pulse. The computerized cycle also allows the user to input background information such as weight, age and sex and to provide Caloric use information based on this background information, resistance values, and RPM's pedaled.

Abstract: The invention provides an exercise cycle with a stationary frame, a seat, a pedal mechanism, and a rotating wheel. Resistance is offered to the rotating wheel by an adjustable brake assembly. A handle bar assembly is pivotally mounted to the frame to move back and forth toward and away from the user positioned on the seat. A locking mechanism is associated with the handle bar assembly, so that with the locking mechanism in a first position, the handle bar assembly is precluded from pivoting. With the locking mechanism in a second position, the handle bar assembly is allowed to pivot toward and away from the user. A resistance mechanism is also associated with the handle bar assembly.

Abstract: An electrical conductivity testing device for detecting mastitis in dairy cows includes an inlet for receiving a sample of milk to be tested, a conductivity cell having a milk flow-through testing passage in flow communication with the inlet, and a milk discharge outlet in flow communication with the conductivity cell, so that a milk sample enters the inlet, flows through the conductivity cell, and flows out through the discharge outlet. The flow described may be continuous or may be discontinuous so that the sample is held in the conductivity cell at least during taking of the conductivity measurement. The conductivity cell is arranged so that it is completely filled with milk during the taking of conductivity measurements. Electrical circuitry is provided to produce an electrical signal proportional to the conductivity of the milk in the conductivity cell.
