    Abstract: A laser flashlight employs an emitter disposed within a housing for emitting a coherent light beam having a gaussian spatial profile along an optical axis toward the exit face of the housing. An optical system disposed within the housing intermediate the emitter and the exit face of the housing includes a laser element pumped by the emitter, a frequency/wavelength converter, and a resonator, to form the coherent light into a laser beam. A beam expander receives the laser beam, disperses the laser beam, and transmits the dispersed laser beam from the light emitting end of the housing into the ambient environment.

    Abstract: A galvanometer unit comprises a limited-rotation motor with a load element such as a mirror attached to a shaft extending from the motor. In a servo loop that controls the angular position of the mirror, a position-sensor attached to the shaft provides position feedback information. The sensor includes a rotor which is positioned at the null point of the fundamental torsional resonance mode of the rotating system, thereby essentially eliminating feedback components resulting from the resonance.

    Abstract: A method for packaging a liquid filled container including the steps of providing a container, placing a capsule defining the cavity in the container, filling the container with a liquid, and allowing a gaseous exchange between the liquid and the cavity to provide a benefit to one of the capsule and the liquid. The invention also includes a method for providing retrievable payload in a liquid filled container that includes the steps of providing a capsule in a liquid filled container wherein the capsule has a cavity and is associated with the payload. The method further including the step of pressurizing the cavity. The present invention also includes a capsule having a body defining a cavity and an opening communicating with the cavity, a payload disposed in the cavity, sealing means for sealing the cavity which contains gas at a first pressure greater than atmospheric pressure when the cavity is sealed, and vent means for selectively venting the pressurized gas from the cavity. Other embodiments of the capsule include a cap engageable with the body at the opening and movable between a sealed position wherein the cap engages the body to seal the cavity and an open position providing access to the cavity. Connecting means and presentation means may also be included with the capsule for coupling the cap to the body when the cap is removed from the opening and for moving the payload toward the opening when the cap is in the open position, respectively.

    Abstract: A galvanometer unit comprises a limited-rotation motor, which has axial symmetry of the major motor components including axial placement of the bearings, stator drive coils, and stator back iron with respect to the magnetic center of the rotor, and which employs a cylindrical magnet having significantly uniform properties along its length. The galvanometer employs independently “hard” and “soft” preloaded bearings, which simultaneously minimize axial displacement and account for thermal expansion of the rotor assembly and which improve the overall efficiency of the galvanometer and extend the service life of the bearings.

    Abstract: A bottom for a paper cup is formed by advancing a punch against a paperboard web to push the web against a cutting edge which cuts out a circular cup bottom blank from the web. The punch is kept in a forward state to clamp an outer peripheral portion of the blank immovably against a surface of a sleeve. A reciprocable draw is advanced against a center portion of the blank to push the center portion into a circular opening of the sleeve while maintaining the clamping force, to cause the center portion of the blank to become stretched. The clamping force is then progressively released to permit the outer peripheral portion to enter the opening and become bent to form a lip extending at a substantially right angle. The lip is compressed within a gap formed between the draw and a surface of the opening. Because of the stretching of the blank, pleats formed in the lip are only in the form of micropleats that are flattened in a non-folded over state.
