Patent number: 4911551Abstract: The measuring apparatus serves for measuring the distance of an object from a measurement surface. The apparatus contains an illumination unit, which is preferably a laser. Furthermore the apparatus contains an optical image reproduction system with which a light ray projected onto the object by the illumination unit is imaged, after reflection, on an optical sensor. A two-dimensional charge-coupled semiconductor sensor should be used as optical sensor, which sensor has a plurality of electrodes arranged in the form of a matrix. To evaluate the position of a light spot-point of concentration on the image region of the charge-coupled semiconductor sensor all pulse trains should be evaluated which can be retrieved from illuminated electrode series. In this way a high resolution is achieved despite a relatively small number of electrodes in any one series.Type: GrantFiled: May 26, 1988Date of Patent: March 27, 1990Inventor: Karl-Erik Morander

Patent number: 4911330Abstract: A service vehicle includes a frame (10) on which a material dispensing system is mounted. The dispensing system includes reservoirs (30, 32) and (34) for various lubricants or the like and pumps (46) for pumping material out of the associated reservoirs (30, 32) and (34). The pumps (46) are driven by hydraulic motors (50) which may receive hydraulic fluid under pressure through electrically operated control valves (76) from a pressure compensated, variable displacement pump (60) driven by the engine (64) for the vehicle. The use of the pressure compensated variable displacement pump (60) achieves operating efficiencies.Type: GrantFiled: October 24, 1988Date of Patent: March 27, 1990Assignee: Iowa Mold Tooling Company, Inc.Inventors: James Vlaanderen, Francis L.

Patent number: 4909363Abstract: A unidirectional no-back device having an input shaft and an output shaft and grounded releasable brake structure for holding the output shaft against rotation. A drive train between the input and output shafts has first and second ball and ramp structures. The first ball and ramp structure is operable upon rotation of the input shaft in either direction by a prime mover to release the brake structure and enable driving of the output shaft by the input shaft. The second ball and ramp structure is responsive to torque flow from rotation of the output shaft in one direction to release the brake structure to permit backdriving of the input shaft and prime mover from the output shaft and is inoperative in response to torque flowing in an opposite direction of rotation of the output shaft so as to not release the brake structure and thus preclude rotation of the output shaft.Type: GrantFiled: June 15, 1987Date of Patent: March 20, 1990Assignee: Sundstrand CorporationInventor: William C. Trommer

Patent number: 4909364Abstract: A latching failure detection mechanism for a rotary drive system is disclosed. A pair of mating clutch jaws are provided, with each jaw torsionally connected to a respective one of a pair of input members, such as the ends of a closed loop drive line. The jaws are relatively axially and rotatably movable. The jaws are movable from a first, inoperative position wherein the jaws simply rotate with the input members and a second, latching position wherein the jaws relatively rotatably move to a latched condition in response to relative failure rotation of the input members, thereby providing a torque path through the jaws in the latching position. An indicator is provided operatively associated with a movable one of the clutch jaws for providing a positive indication that the jaws have moved to the latching position.Type: GrantFiled: May 12, 1988Date of Patent: March 20, 1990Assignee: Sundstrand CorporationInventor: Duane H.

Patent number: 4909301Abstract: A method of making a bearing composed of a bronze preform having aluminum or aluminum alloy cast thereabout. The method includes the step of placing the bronze preform in a mold so as to be supported at one end thereof. The bronze preform is formed of a bronze having lead with a determining melting point and boiling point. The method also includes the step of providing molten aluminum or aluminum alloy to be fed into the mold after the bronze preform has been placed therein. The molten aluminum or aluminum alloy is at a temperature between the melting point and boiling point of lead in the bronze of the bronze preform. The method further includes the step of feeding the molten aluminum or aluminum alloy into the mold under pressure after the bronze preform has been placed therein. The molten aluminum or aluminum alloy contacts the bronze preform and produces a molten lead during partial erosion of the surface thereof.Type: GrantFiled: October 14, 1988Date of Patent: March 20, 1990Assignee: Sundstrand CorporationInventors: Robert M.

Patent number: 4907832Abstract: A secondary locking mechanism having a lock mountable to a sliding closure, such as a sliding window or sliding patio door, and a stop block mountable to a frame member which mounts the sliding closure. The lock has a pivotable stop arm which is spring-retained in an inactive position wherein a foot of the stop arm travels in a path of movement along with the sliding closure which is out of interfering relation with the stop block and an active position wherein the foot of the stop arm is positioned to engage beneath an inclined end of the stop block to prevent further movement of the sliding closure in a direction toward the stop block. One or more stop blocks can be mounted in various positions on the frame member to assist in locking the sliding closure in a fully-closed position and to prevent further opening movement of the sliding closure when it is in a partially-open vent position.Type: GrantFiled: August 29, 1988Date of Patent: March 13, 1990Assignee: Truth IncorporatedInventor: Whitley Pemberton

Patent number: 4902265Abstract: In order to provide smoother transition for speed changes, a variable speed pulley having a movable sheave half and a fixed sheave half is provided with a torque cam. A spring biases the second sheave half axially of the first sheave to vary the width of a belt receiving groove. The torque cam forces the second sheave half in the same direction as the spring when the torque of a load operatively connected into the pulley assembly is increased. A centrifugal thrust arrangement urges the second sheave half in a direction reverse to the direction caused by the spring responsive to the rotational speed of the pulley.Type: GrantFiled: September 1, 1988Date of Patent: February 20, 1990Assignee: Mitsuboshi Belting Ltd.Inventor: Hiroshi Takano
