Abstract: Abstract of the Disclosure A gas cylinder for use in die systems for forming lightweight parts.   In one form, the cylinder forms a self contained gas spring which is interchangeable with a coil spring that is constructed such that it is not adversely affected by the deleterious effects of oil and other contaminants.  The gas cylinder comprises a one-piece cylindrical upper body having a base wall and a peripheral wall and a hollow rod extending upwardly into the cylindrical body such that the upper body completely encircles and encloses the upper end of the rod.          The rod has a base having an outer diameter greater than the diameter of the rod.  The peripheral wall of the cylinder and the outer diameter of the base have substantially the same diameter such that the cylinder can be positioned in a recess of a press or die in place of a coil spring.  The cylindrical body and  rod  include  interengaging  portions  limiting  axially outwardly movement of the cylinder relative to the rod.  In one form, the cylinder further includes a charging valve in the base of the rod through which gas may be introduced for charging the space between the cylinder and the rod and a pressure relief rupture disk in the base wall of the cylindrical body.   In another form, the opening in the hollow rod is exposed and the base is formed with an axial projection that is threaded for engagement into a manifold or valve block used in the die system.

Abstract: ABSTRACT OF THE DISCLOSURE      The present invention involves a liquid jet propelled transporter and launcher toy.  The launcher has a housing which includes a reservoir for holding a predetermined amount of liquid therein which is less than the volume of a transporter container and related to the volume of the transporter container.  There is also a reservoir fill port and cap to enable a user to fill the reservoir and close it.  The launcher also has a jet tube receiver and adapted to receive a jet tube of a transporter.  A pump is connected to the housing and may be contained within the housing and this includes manual means for actuating the pump as well as a one way valve from the pump to the reservoir.  There is a transporter latch mechanism located on the housing and means or the transporter for releasing the latch mechanism so as to launch a transporter.  The transporter includes a container for receiving liquid from the reservoir of the housing as well as a jet tube extending from the container which is adapted to fit onto the jet tube located in the housing.  The transporter has a simulated transporting structure attached to the propulsion container.  This may take the form of a plane, glider, rocket, land vehicle, water vehicle or under water vehicle.  The liquid is first stored in the reservoir and then pumped into the propulsion container of the transporter by means of actuating the pump and further actuation of the pump creates a substantial positive air pressure within the reservoir and within the propulsion container of the transporter. Thereafter, the transporter may be released by the release means and freely advances away from the housing by jet propulsion.  In preferred embodiments the water to air ratio and the air pressure itself are such that the transporter is transported in two different phases, one being a positive air pressure thrust and the other being a combination of air and liquid such as water to create a jet stream thrust.

Abstract: A sensor determines a wide range of air-to-fuel ratio values (A/F) about the stoichiometric A/F in a gaseous mixture which has oxidizing and reducing species as might be found in an automotive exhaust.  The sensor includes a surface that serves simultaneously as the working electrode of a solid-state oxygen concentration cell and as a surface whose workfunction changes from a higher to a lower value as the oxidizing and reducing species in the adjacent gas phase, and in interaction with the surface, pass from an excess oxidizing to the excess reducing condition about the stoichiometric ratio. In one embodiment, the surface exposed to the gas in question is the emitter electrode of a thermionic diode which emits positively charged alkali ions into the exhaust ambient where they are collected by a nearby collector electrode.  Changes in the ratio of the oxidizing and reducing species about the stoichiometric ratio produce corresponding changes in the thermionic emission.  Oxygen pumping to or from the working electrode modifies the thermionic emission in a systematic way to provide a pumping method of operation in which the magnitude of the pump current required to maintain the thermionic emission current at some preset value despite changes in the A/F ratio of the ambient leads to a relationship between pump current and A/F that can be used to sense the A/F.

IPC: G01N19/02
Filed: 1993-07-13
Abstract: ABSTRACT An apparatus and technique for determining the abrasion potential for tire treads is presented. A tire is rotatably and forcefully brought into contacting engagement with a reflective surface received upon an illuminated glass plate. A charge coupled device monitors the internal reflection light which evidences agrey level corresponding to the force of engagement between the associated portion of the tire and the glass support plate. A marker is placed upon the tire centrally within a region of interest. The video image of the marker and region of interest is analyzed as to slip and force at that area. The product of the slip and force functions is an indication of frictional work at the interface between the tire and support surface and is correspondingly an indication of the propensity of the tire to wear.

Abstract: A flanging head (10) assembly having a cluster of freely rotatable spin flanging rollers (12) includes a stop ring (26) against which the flange (68) hits during the final flange forming stages to limit the flange to a specific diameter. To prevent the flange from entering the crack (72) formed between the rotating roller and the stationary stop ring, there is provided a step (80) spacing the stop ring surface (70) from the roller forming surface (66). In this manner, as the terminal edge of the flange (68) slides around the flanging roller during final forming, it will pass over the crack (72) and across the step (80) to lodge in a corner (85) formed between the step and stop ring surface. In a preferred embodiment, the step is a conical surface extending from the stop ring surface in a direction away from the can bottom. This conical surface extends radially inwardly a sufficient distance to contact unsupported flange portions between the flanging rollers to limit the degree of elastic sagging of these portions. <IMAGE>

Abstract: HIGHLY DEPRESSED, HIGH THERMAL CAPACITY, CONDUCTION COOLED COLLECTOR              ABSTRACT OF THE DISCLOSURE    An electron collector is provided for collecting spent electrons generated by a charged particle device after  passage  though  an  interaction  region  of  a  RF circuit.  The collector has a centerline and comprises an outer structure which is coupled to the RF circuit.  An inner  structure  is  within  the  outer  structure,  and receives the spent electrons.   A negative voltage is applied to the inner structure, which forms an electric field between the inner and outer structures.  A plurality of  thermally  conductive  and  electrically  insulative standoff assemblies extend between the outer and inner structures.   Each of the assemblies comprise a ceramic planar member centered within outer walls providing a double-ended cup shape, and conductive plugs which adjoin each side of the planar member with the respective one of the inner and outer structures.  An axis of symmetry of the assemblies  lies perpendicular to a radial vector extending from the centerline, and lies parallel to the electric field vector.   Since the conductive plugs are partially surrounded by the outer walls, a relatively long surface voltage breakdown path is provided between the plugs, while the thermal path through the planar member is relatively short.
