Andrew Kropp has filed for patents to protect the following inventions. This listing includes patent applications that are pending as well as patents that have already been granted by the United States Patent and Trademark Office (USPTO).

  • Patent number: 8746316
    Abstract: A clutch mechanism for a tape dispenser, for example, includes a first reel, a second reel, a biasing element, and a friction element. The first and second reels are rotatably disposed on first and second shafts. The biasing element is disposed between the second reel and second shaft such that the second reel is movable in a radial direction between first and second positions relative to the second shaft and the biasing element biases the second reel into the first position. The friction element extends around the first and second reels and arranged to generate a first normal force acting on the second reel when the second reel is in a first position, relative to the second shaft, and a second normal force acting on the second reel when the second reel is in a second position, relative to the second shaft.

  • Patent number: 8746313
    Abstract: A correction tape dispenser includes a body having a plurality of body teeth disposed on an inner surface thereof, an applicator tip mounted in the body, and a supply and take-up assembly mounted in the body, the supply and take-up assembly being biased away from the body teeth with a biasing element. The supply and take-up assembly includes a supply reel and a take-up reel. The supply reel and the take-up reel have a common axis of rotation. One of the supply reel and the take-up reel include a plurality of teeth that engage the plurality of body teeth during correction tape re-tensioning when the biasing force from the biasing element is overcome.

The first and second reels are rotatably disposed on first and second shafts. The biasing element is disposed between the first reel and shaft such that the first reel is movable in a radial direction relative to the first shaft. The friction element includes at least a portion that is disposed between the first reel and the second reel and arranged to generate a first normal force when the first reel is in a first position, relative to the first shaft, and a second normal force when the first reel is in a second position, relative to the first shaft.

  • Patent number: 6258497
    Abstract: A homogeneous marker is formed, possibly by the adsorption of trace amounts of an ambient material such as carbon monoxide gas, at a surface of a deposited material when the plasma in momentarily interrupted during plasma enhanced chemical vapor deposition or other deposition processes involving the presence of a plasma. When the deposited material is etched, the resulting crystal dislocations or adsorbed gas is detected as a marker by optical emission spectroscopy techniques. The accuracy of an end point determination of the etching process can be increased by providing a sequence of such markers within the bulk or volume of the deposited material. The markers, being merely an interface such as a slight crystal dislocation in otherwise homogeneous material, do not affect the electrical, chemical or optical properties of the remainder of the predetermined deposited material and thus the homogeneity of the deposited material is not significantly affected.
