Abstract: A diaphragm carburetor for an internal combustion engine and method of assembly includes attaching an air-fuel mixing body to a fuel metering chamber assembly independent from assembling the fuel metering chamber assembly. The fuel metering chamber assembly has an upper body and a lower body attached to one another by at least one fastener with a diaphragm carried therebetween. A fuel metering chamber is defined on one side of the diaphragm and an atmospheric chamber is defined on another side of the diaphragm. Another fastener attaches the fuel metering chamber assembly to the air-fuel mixing body independently from the fastener attaching the upper and lower bodies together. Accordingly, the fuel metering chamber assembly is removable from the air-fuel mixing body without removing the fastener attaching the upper and lower bodies to one another preferably for cleaning of a fuel nozzle that when assembled projects into an air-fuel mixing passage in the mixing body.

Abstract: An apparatus (10) for generating a surface (S) on a workpiece (W) is proposed, which comprises a workpiece chuck (17) having a longitudinal axis (L), a spindle (18) for rotating a fly cutting tool (20) having a tool tip (48), and a moving device for moving the spindle generally transverse to the axis (L). The spindle further has a rotary encoder (42) for detecting an angle of tool rotation (?), wherein the chuck is operatively connected with a fast workpiece servo (50) capable of moving it over short distances at high velocities. The servo is controllable taking into account the given angle of tool rotation so that the workpiece can be advanced toward and retracted from the tool in a defined manner while being cut by the tool tip. The limited geometry of the tool can thus be modified by moving the workpiece relative to the tool tip.

Abstract: A workholding apparatus including a body and a drive member carried by the body, so that the drive member and body partially define a fluid chamber therebetween for containing a fluid. The drive member includes an annular flange that axially abuts and that attaches to the body to resist torsional twisting of the drive member relative to the body. A driven member is also carried by the body and includes multiple displacement reliefs therein. Interengagement features are provided between the driven member and other components of the workholding apparatus, such as the drive member, to resist torsional twisting of the driven member.

If so, the components can be downloaded and installed without further action by the user. A distribution tool is provided for software distribution and upgrading over the network. Also provided is a user profile that is accessible to any computer on the network. Furthermore, multiple users of the same computer can possess Internet web resources and files that are personalized, maintained and organized.

Abstract: Injectable structural adhesives, methods of using the same, and products formed therewith, are described. The adhesive is introduced through a first opening into an internal cavity formed between two or more components. The adhesive is then permitted or forced to flow through the internal cavity, substantially filling the cavity, until it reaches a second spaced opening. Any air contained within the internal cavity is removed by the flow of the adhesive.

Abstract: An external rear view mirror for vehicles includes a mirror head the is fixedly secured to the vehicle. A housing defines an opening and a housing rear wall. The housing rear wall defines a recess that extends along a portion thereof. A turn-signal lamp, designed to generate light, is fixedly secured to the housing rear wall. The turn-signal lamp extends into the recess. The turn-signal lamp includes a light lens that covers the turn-signal lamp. The light lens has an outside surface. The external rear view mirror also includes an optical waveguide that guides the light generated by the turn-signal lamp around the mirror head, whereby the optical waveguide is fixedly secured to the light lens.

Abstract: An apparatus for placing mold charges into a mold of a compression molding machine includes at least one mold charge pick-up cup for receiving a severed charge of molten plastic, a vacuum source for applying a vacuum to the pick-up cup to retain the mold charge in the cup, and a source of gas (such as air) under pressure for periodically applying gas to the cup to release the mold charge from the cup. In one exemplary embodiment, the vacuum source applies a continuous vacuum to the cup, and the source of gas under pressure periodically applies gas to the cup to overcome the continuous vacuum at the cup. In another exemplary embodiment, vacuum and gas under pressure, are alternately applied to the cup. The vacuum source preferably includes a vacuum generator coupled to the source of gas under pressure for generating the vacuum to be applied to the cup. The vacuum source preferably includes a vacuum pump coupled to the source of gas under pressure for generating the vacuum to be applied to the cup.

Abstract: A limited slip differential comprises a housing having an input, a first output, and a second output rotatably mounted in the housing. A friction clutch in the housing limits slip between the first output and the second output, and a mechanism in the housing applies an axial force to the friction clutch. The mechanism includes a rotatable actuating plate and a non-rotatable, back-up plate. A motor that rotates the actuating plate is controlled by an electronic motor control which has a feed back that is responsive to the force applied by the mechanism to the friction clutch. In one embodiment, the feed back measures the angular position of the rotatable actuating plate which is mounted on an angular contact bearing. The stain or slight axial movement of the outer race of the angular contact bearing is measured to provide the feed back to the electronic motor control.

Abstract: A method of making an identifiable article such as a container or container preform. A molded plastic container or container preform is provided that includes a wall having at least one layer of matrix resin and at least one layer of barrier resin that is blended with an additive. The wall has at least one localized portion of predetermined geometry in which the barrier layer is thicker than surrounding portions of the wall, and within which the additive is discernable under visible or UV light so as to provide a means to prevent use of counterfeit containers.

Abstract: A vehicle tie rod adjustment device for changing the toe of a vehicle wheel by adjusting the overall length of a tie rod assembly. The tie rod adjustment device generally includes a housing, a gear train, an adjustable gear head, and a nut runner. The pivotal gear head threadably adjusts the tie rod assembly by rotatably engaging a hex or flatted portion and a lock nut, and includes one or more roller elements spaced around a guide fork recess to reduce a sliding friction with the tie rod assembly. According to another embodiment, the tie rod adjustment device includes a locking mechanism for maintaining the adjustable gear head in a proper alignment so that one or more components of the gear head can be removed.

Abstract: A fiber placement machine has a creel that supplies a fiber band to a presser member that applies the fiber band to a tool or form. The presser member is part of a head that is attached to the creel of the machine by a wrist that provides movement about yaw, pitch and roll axes with respect to the creel. The fiber band is supplied by a fiber band delivery system that is associated with the wrist and that is characterized by a capability to twist the fiber band in two stages about the yaw axis or the roll axis.

Abstract: A fuel system has a jet pump assembly that fills a fuel reservoir for providing a reliable source of fuel to an electric motor fuel pump located in a fuel tank for a combustion engine. The electric fuel pump preferably delivers fuel at a controlled pressure to a series of fuel injectors of the engine. A small portion of the fuel exiting the electric fuel pump is diverted to the jet pump assembly that aspirates fuel from the fuel tank and into the reservoir. A biased normally closed pressure responsive valve prevents fuel flow to the jet pump when the electric fuel pump is running under impaired conditions, thus providing all the fuel to the combustion engine typically during cold engine start conditions.

Abstract: In a multi-cylinder piston engine, a diagnostic method of determining if there is low compression in a cylinder (5) by using a split engine brake (18) and turning the engine brake on during one cycle and the engine brake off during another cycle and measuring any difference in the power contribution of the engine between the two cycles.
