Abstract:
Tires (11) are measured (15) for a parameter correlated to a tendency to contribute to steering pull when used on a vehicle (38). A group of the measured tires (10) is then ranked (25) into a successive series by ordering the parameter measurements of the tires (10) in the group non-decreasingly or non-increasingly. A set of at least two tires (12) of substantially consecutive rank are then selected for mounting on the same vehicle (38) in order to reduce steering pull.
Abstract:
An object (10) is positioned in fixed relation to a measuring axis (36) without regard to centering the object (10) on the axis (36) and at least one series of data samples (101-109) correlated to the distance between the measuring axis (36) and a series of points at angularly spaced intervals on at least one surface feature (14, 17) of the object (10) are used. To determine the center (165) of the first surface feature (14) the samples are analyzed to identify samples (102, 106, 108) corresponding to points lying on a maximum inscribed circle (169) whose center (165) corresponds to the surface feature (14). To measure a second surface feature (17) the center (165) of the first feature (14) is determined to define a vector indicating the positional offset between the measuring axis (36) and center. A second signal (74) is adjusted with that vector to provide a coordinate-corrected signal to be used as a basis for a centered measurement.
Abstract:
A precision, highly reliable, positive displacement, pneumatic lubricator for pumping lubricant to a tool and work piece during machining operations; and for delivering compressed atomizing air thereto. The lubricator pumps lubricant substantially continuously at highly accurate, very low flow rates which can be minutely varied according to the needs of the user. The lubricator's piston (80) delivers one pulse of lubricant for each input air pulse which is supplied to the lubricator from a source of input air pulses (70). The lubricator includes internal check valves (130) for preventing back flow of lubricant into the lubricator's lubricant source, and for preventing back flow of pumped lubricant into the lubricator (148). The lubricator has an adjustable stop (82) which controls the stroke of its piston, and which thus controls the amount of lubricant which is pumped by each pumping stroke of its piston. The lubricator also has positive stops for the maximum and minimum adjustment of its adjustable stop. The positive stops prevent endless turning of the lubricator's adjustable stop in either direction with no change being made in the amount of lubricant pumped by each pumping stroke of its piston. The lubricator's valve body is made stackable so that one lubricator may comprise several valve bodies; each valve body being able to independently deliver lubricant and atomizing air to its respective tool and work piece through coaxial atomizing air/lubricant output lines. If the lubricator has more than one valve body, their lubricant input means, air pulse input means, air relief means, and compressed air input means are in fluid communication with each other.
Abstract:
This invention relates to a device to be used for tending straps and also to be used as a whistle. More particularly, this invention relates to a device (11) for tending straps with a whistle (16) integrated within the device (11) where both the whistling and strap-tending functions are independent. While whistles may be included as individual pieces of gear, they are often not available when desired. This invention facilitates the inclusion of a whistle (16) by combining it with items (11) designed to tend the straps on gear that is more commonly carried.
