Abstract: An apparatus to auto-adding an energy-saving activator has a container and a control unit. The container has a heater electrically connected to a control circuit of the control unit. The control unit has a vibration sensor and a sound sensor. When both the vibration and sound sensors transmit signals, the control circuit will actuate the heater to heat the energy-saving activator in the container so that the heated energy-saving activator turns into vapor and leaks out of the container toward the internal combustion engine to decrease the carbon deposits. Using both the vibration and sound sensors is in order to actuate the heater correctly without erroneous judgment. The heated vapor drafts into the internal combustion engine at once to mix with the fuel so that the fuel is burned oxyfuelly and completely to efficiently decrease the carbon deposits. Therefore, the efficiency of the internal combustion engine is also enhanced.

Abstract: An ultrasonic cleaning tank for use in cleaning electronic parts having a top portion and a bottom portion operably divided by a perforated dispersion plate. The cleaning tank is assembled to avoid internal projections or obstructions within the top portion to create a piston-like, laminar flow region. The dispersion plate is constructed to provide a backpressure within the bottom portion so as to promote even flow of a cleaning fluid through the perforations. The cleaning fluid flows upward past an electronic part. At the same time, an ultrasonic transducer supplies ultrasonic energy within the cleaning fluid creating cavitation such that any particulate matter is scrubbed from the electronic parts. The particulates are subsequently carried upward by the laminar flow and over a tank lip. The cleaning tank can be used in either a batch or recirculating mode.

Abstract: An apparatus and method for induction hardening a workpiece can first include fastening a workpiece in a clamping assembly. The clamping assembly is provided with a plurality of hardness testing devices. Alternatively, one or more hardness testing devices are provided directly to the induction hardening head. The induction hardening head is moved over the workpiece to harden a portion thereof, such as an edge. Then, a series of hardness measurements are taken with the plurality of hardness testing devices to allow an operator or controller to adjust the input to the induction hardening head. This allows the workpiece to be provided with a predetermined hardness profile within a desired tolerance.

Abstract: The method of controlling a linear vibration welding apparatus, in accordance with the invention, may comprise the steps of: fastening a first workpiece portion in a fixed position; fastening a second workpiece portion to a reciprocating member; energizing a first single winding magnet with direct current power to create a magnetic field; sensing a location of the reciprocating member with respect to a zero point; and energizing a second magnet when the reciprocating member has crossed the zero point when moving towards the first magnet. The linear vibration welding apparatus in accordance with the invention may comprise: a frame; a flexure array; a first magnet assembly; a second magnet assembly; a digital controller; and direct current amplifiers for powering the magnet assemblies.

Abstract: A hollow camshaft (19) lubrication system for aircraft engines that supplies lubricant (14) to cam lobe surfaces (25) from the interior surface (22) of the hollow camshaft (19) even during periods when aircraft operation moves the rotation axis of the hollow camshaft (19) from horizontal.

Abstract: Method for cleaning or decoring a casting, wherein that, separately or in combination: the said casting may be excited by an ultrasonic source of vibration, to allow residual material in contact with the walls of the said casting to become detached, this casting resting on a number of anvils placed on vibrating means supporting the casting and in contact with a number of sonotrodes, the said casting may be beaten at a very low frequency so as to cause large-sized internal residue such as a sand-based core insert to crack up, vibrating means may be used to impart a low-frequency linear vibration to this casting so as to break up and fluidize the cracked bits, the material issuing forth from the said casting may be extracted using a stream of fluid.

Abstract: A chamber having selectable and controllable access through which a process part is placed within and removed from a processing system. The chamber is designed to selectively isolate the external and internal environments of the process system during delivery and removal of the process part.

Abstract: In a vapor drying system, solvents such as isopropyl alcohol (IPA) are boiled and condensed to provide a means of removing water and other contamination from process parts loaded into the equipment. The parts enter the apparatus via an automated lift assembly. Upon entering the vapor zone, solvent condenses on the parts and fixtures due to a temperature differential, displacing the contaminants. This condensate/contaminant waste stream gravity drains to a buffer tank below via a sloped, temperature-controlled drip tray. After vapor condensation on the parts ceases, drying is accomplished using superheated vapors formed in a stabilized zone generated by one or more offset boil sumps and separate vapor heat exchangers. Any liquid solvent remaining on the parts is flash-dried in the vapor zone, so that parts emerge clean and dry. The invention incorporates a computer-implemented PLC to control process parameters, cover mechanism, transport mechanism, safety features during operating, idle and standby conditions.

Abstract: A method of cleaning a metal part such as a casting, wherein the part to be treated is placed on a support plate inside a container full of fluid, and at least one vibration generator is positioned in contact with the part. Generators are used to excite one natural mode of vibration of the part, causing the fluid inside the part to cavitate. The vibration generators in contact with the part operate with a running cycle for the vibration sources which is optimized by managing the state of the sources.

Abstract: A system for fusion bonding several attachments to a relatively large and bulky thermoplastic article employs means for fixedly securing the article, and a movable fixture selectively positionable relative to the thermoplastic article. The fixture includes a base plate held stationary during bonding operations, a gripping device supporting the thermoplastic article and longitudinally reciprocable relative to the base plate, and a pair of arms supporting a platen or other heating tool, also longitudinally reciprocable relative to the base plate. The tool supporting arms further can be pivoted to move the heating tool between an aligned position between the thermoplastic attachment and fixed thermoplastic article, and a remote, withdrawn position, to allow longitudinal movement of the attachment into engagement with the thermoplastic article, following use of the heating tool to simultaneously fuse selected surface portions of the thermoplastic article and attachment.

Abstract: A method for fusion bonding a pair of articles consisting of a high melting point thermoplastic material which includes the steps of bringing each surface to be bonded into engagement with the contact surface portion of a heated platen, maintaining the engagement until the surface becomes fused, and thereafter bringing the fused surfaces together in face-to-face relationship until the fused surfaces become solidified. The method further includes the step, in each operative cycle, of abrading the contact surfaces of the platen to renew and expose the metallic surface thereof for engagement with the surface of the next thermoplastic article to be treated.
