Abstract: An arrangement for removing excess material from an object surface, to provide a desired finished surface. Holes are drilled into the object so that the bottoms of the holes lie on the desired finished surface. The holes have a shape so that the observed hole diameter at the prevailing surface of the object is dependent on the hole depth and thereby dependent on the amount of material remaining to be removed between the prevailing surface and the desired finished surface. The prevailing surface is continuously observed and measured, and the depths of material to be removed in a sequence of steps is calculated dependent on the measurements of the prevailing surface and the coordinates of the desired finished surface. As a result of the calculations, the depth of material removed during each step is controlled, so that upon carrying out a sequence of such steps, the surface exposed on the object after the last step has been carried out, coincides with the desired finished surface.

Abstract: A fuse element for an electrical cartridge fuse comprises a fusible wire secured to opposite end zones of an insulating strip by metallic layers sprayed onto the end zones. The insulating strip has a slot therein between the end zones to prevent the fusible, central section of the wire from contacting the strip. The fuse element is disposed in an insulating barrel and the layers are soldered to end caps of the barrel to connect the fusible wire thereto. Fuse elements of this construction are produced by disposing a fusible wire along a continuous strip of insulating material formed at equally spaced intervals with slots and spraying the metallic layers onto the strip between the slots so as to adhere the fusible wire to the strip. Thereafter, the strip is severed at the zones between the slots so as to produce individual fuse elements. This method of manufacture facilitates the production of cartridge fuses utilizing small diameter fusible wires.

Abstract: A manifold-to-stack seal and sealing method for fuel cell stacks. This seal system solves the problem of maintaining a low leak rate manifold seal as the fuel cell stack undergoes compressive creep. The seal system eliminates the problem of the manifold-to-stack seal sliding against the rough stack surface as the stack becomes shorter because of cell creep, which relative motion destroys the seal. The seal system described herein utilizes a polymer seal frame firmly clamped between the manifold and the stack such that the seal frame moves with the stack. Thus, as the stack creeps, the seal frame creeps with it, and there is no sliding at the rough, tough to seal, stack-to-seal frame interface. Here the sliding is on a smooth easy to seal location between the seal frame and the manifold.

Abstract: The degree of saturation of a vapor in a chamber such as a curing oven is controlled by sensing the vapor dew point and varying the rate of removal of such vapor from the oven in response to a comparison of the sensed dew point with a predetermined dew point. This comparison may also be effected by comparing the difference between the actual dew point and oven temperature with a predetermined difference and controlling the rate of vapor removal in response to variations between the actual and predetermined differences. Alternately, a predetermined ratio between dew point and oven temperature may be maintained. By controlling the dew point of the vapor, i.e. degree of saturation, condensation in the oven is precluded while still permitting high solvent vapor concentrations which in turn facilitate recovery of solvent exhausted or removed from the oven.

Abstract: An anatomically manipulable toy in the form of a rotatable implement comprising a shaft, a massive body portion rigidly attached to the shaft, and a contact element at one end of the shaft. In operation, the rotating implement is generally supported by placing the contact element on a portion of the user's anatomy, typically a hand, with the shaft horizontal, rotation having been initiated by manually imparting a torque to the implement, typically at the shaft. The contact element rolls on the user's anatomy, thereby producing a linear translation therealong. The weight of the implement acting at a horizontal separation from the point of contact causes a precession of the spinning implement about the vertical axis through the point of contact. The rate of precession depends on the rate of angular rotation and the distance of horizontal separation.
