Abstract: A test instrument for determining whether an apparatus has a high voltage on the chassis thereof includes a meter, a probe and a socket for receiving a plug from the device being tested. The device also has a plug for insertion into an AC outlet. The test device first tests to determine that the AC outlet into which it is plugged is properly configured, then tests for a voltage on the chassis of a tested apparatus. The test is undertaken by connecting both the high and low contacts of the plug from an apparatus to be tested to the high voltage side of an outlet and connecting the probe to the ground contact of an outlet. Thereafter, when the probe is touched to the chassis of the apparatus the meter will indicate whether a voltage is present on the chassis of the appliance.

Abstract: A spreader is attachable to a conventional lawn mower to spread granular material over the area cut by the mower. The spreader has a hopper, at least one adjustable orifice at the bottom of the hopper, and a rotating regulator for dispensing granular material behind the lawn mower. In one embodiment, a first sprocket attached to the wheel of the lawn mower, and a second sprocket attached to the spreader receive a chain for driving the rotating regulator of the spreader. In a second embodiment, the spreader is driven by a pair of bevel gears, one of which is mounted on the rear axle of the mower. A novel drive does not convey rotational movement to the impeller of the spreader when the mower is moved a short distance backwards. Also, the lever operating the clutch to engage power to the Pear wheels simultaneously operates a stop to block the flow of particulate matter out of the hopper of the fertilizer spreader.

Abstract: A valve operating machine has a reversable motor and a drive assembly for turning the stem of a valve, and a sensor for determining the torque applied to the valve stem. The amount of torque applied to the valve stem is regulated so as not to exceed the torque limits of the valve. The machine will gradually apply greater amounts of torque in opposite directions until the valve has become unfrozen. Thereafter, the valve will be rotated until the opening or closing cycle has been completed. When an increase in torque is detected, the machine will reverse to unjam a valve, and where such reversal does not result in further forward movement, the machine will terminate the cycle.

Abstract: A cover for an oil hub extending through a truck wheel has a tubular body with a transverse surface at one end thereof. The inner diameter of the tubular body is a little greater than the outer diameter of the cylindrical section of the oil hub around which the body is fitted. A compressible sleeve, typically made of a foam rubber or the like, has an inner diameter a little less than the outer diameter of the cylindrical section of the oil hub, and has an outer diameter which is larger than the inner diameter of the tubular body of the cover. The cover is retained over the compressable sleeve by the radial force of the sleeve and by a double sided tape which is applied to the outer surfaces of the compressible sleeve and across the distal end of the oil hub.
