An apparatus and method for automatically adjusting the valve lash of an internal combustion engine is provided. In another aspect of the present invention, a probe is employed for verifying and/or setting valve lash settings in an automated manner. A further aspect of the present invention does not require determination of a zero lash position or reference datum prior to adjusting the valve lash adjusting screw for desired lash.

Valve lash adjustment apparatus and method

An apparatus for automatically feeding an oil filter(s) into a crushing zone to shear a canister from a connector plate. The apparatus feed the oil filters into the crushing zone one at a time for the crushing by a movable wall against a fixed wall () to flatten the canister while blade shears the canister from the connector plate. The apparatus enables capture of oil and recycling of the canister and connector plate.

Method and apparatus for recycling oil filters

The invention provides a method for automatically processing multiple used oil filters ( ) used for internal combustion engines for disposal, in particular for disposal in which essentially all of the residual oil is removed making the crushed canister ( A) and internal element a non-hazardous material and making the connector base plate ( A) available for recycling as scrap steel.

The preferred embodiment of a masking apparatus is adapted to mask the overspray of a coating applied by a spraying device. In another aspect of the present invention, a coated article or part includes a member with an inner surface and at least one opening. The inner surface is sprayed with the coating. In yet another aspect of the present invention, the apparatus includes a deformable masking cup which is operably located adjacent to the opening in the article.

A thermal spraying system includes thermal spray material, an electrical energy thermal spraying device atomizing and spraying the thermal spray material, a power supply supplying electrical power to the spraying device, a sensor monitoring a power characteristic of the supplied electrical power, and a feed rate control module adjusting a feed rate of the thermal spray material based on the monitored power characteristic.

Arc control for spraying

Disclosed are a method and apparatus for coating the interior surface of a cylinder wherein separate consumable electrodes are fed to an arc formed between a rotating non-consumable electrode and directing an atomizing gas through the arc formed to carry the molten metal of the consumable electrode to the cylinder wall to coat the wall and wherein a first consumable electrode in introduced in the cylinder bore with a rotating thermal spray head and a second consumable electrode is introduced into the cylinder from an end opposite the rotating non-consumable electrode and wherein either or both consumable electrodes may be utilized to form deposits on the cylinder of mixed or alternative composition.

Method and apparatus for dual coat thermal spraying cylindrical bores

Disclosed are a method and apparatus for coating the interior surface of a cylinder wherein a consumable electrode is fed to an arc formed between a rotating non-consumable electrode and directing an atomizing gas through the arc formed to carry the molten metal of the consumable electrode to the cylinder wall to coat the wall and wherein the consumable electrode is introduced into the cylinder from an end opposite the rotating non-consumable electrode.

A fastener tensioning method wherein pre-tensioning fastener tightening history acquired during the tightening of the fastener prior to the point of proportional tensioning of the fastener is utilized to modify the tightening cycle occurring after the point of proportional fastener tensioning to reduce the resultant tension scatter while using a tightening perimeter such as torque as an indicator of fastener tension.

Method and apparatus for monitoring and controlling tightening of

A crankshaft bearing inspection system for confirming the presence of bearing inserts and the proper amount of bearing crush during assembly of reciprocating machines accomplished by measuring a fastener tension related function and a function fastener rotation, and evaluating the curves thus obtained to confirm and identify a characteristic signature of the bearing presence as, for example, a first constant rate of tension increase followed by a second increased constant rate of tension increase falling within expected inspection limits.

Method of inspecting bearing insert assemblies

A roller element for a powered-roller tarnsfer system has a plurality of lubricant pressure relief areas about or in the bearing surface to increase and provide consistent rotary drive power transmitted from a powered axle to the roller.

Friction control for bearing surface of roller

Disclosed is a method and apparatus for cold testing of typical piston engines to determine their internal integrity and tolerance prior to further testing or use which could be destructive if a defect exists. A source of pressure oil is fed to the normal engine oil pressure system while the engine is slowly rotated. The amount of oil flow is measured and recorded by a unique orifice flow device which yields a differential pressure signal in proportion to the oil flow as the engine is rotated. The variation in oil flow in selected segments of rotation is analyzed to determine the engine condition. Such common assembly faults as missing rod or main bearings, loose bearing caps, or excessive bearing clearance may be detected and isolated for repair.

Engine cold testing

A fastener tensioning method and apparatus for obtaining a desired degree of tension in a fastener. The embodiment of this invention described utilizes the slope of the change in torque per change in rotation gradient to predict a rotation starting point independent of the rotation that occured in the torquing cycle up to the point of establishing a constant gradient. In the constant slope or gradient area of the torque rotation curve, rotation is considered linearly proportional to the tension in the fastener. A prescribed additional rotation is applied to the fastener utilizing the threads as a micrometer device for stretching the bolt to achieve the desired tension or fastener strain level. With appropriate system monitoring such as the total rotation, the maximum torque applied, the gradient slope, etc., the system can be adapted to inspect the fastener for applied tension as well as accurately control tension level.

Method and apparatus for fastener tensioning

A fastener tensioning system for use with torque producing power tools, such as, nut runners or the like. The system includes apparatus to rotate the fastener and determine when the fastener has been driven to its yield point in tension, and, thereafter, the fastener is backed out a precise amount of rotation to establish a level of tension in the fastener below the yield point. The method of this invention improves upon the conventional turn-of-the-nut method for fastener tensioning; in that, the precise fastener rotation is started from a relatively well-known and well-defined point as opposed to a arbitrary predetermined low level of torque. In addition, the method assures by inspection the proper condition of the bolt and thread prior to making the final tensioning step.
