Abstract: A composite capacitor/inductor assembly has been developed that merges the capacitance utilized for energy storage into the inductor, creating a consolidated electrical component. The composite capacitor/inductor is capable of functioning in those applications requiring resonant circuits for frequencies in excess of 100 MHz. The composite nature of the device reduces by one-half the number of components required to produce a resonant circuit.

Abstract: A hand-held power tool includes a housing having spaced front and back walls, and an output shaft mounted in the housing for rotation in one direction or the other on an axis extending transversely with respect to the walls. The shaft has an outer end portion projecting out from the front wall for reception of an attachment for the tool. A ratchet wheel on the shaft in the space between the walls is adapted to be driven in one direction or the other for rotating the shaft in the one direction or the other. The ratchet wheel has a side face facing a fixed surface on one of the walls and a plurality of recesses extending inward from the side face spaced at intervals around the axis. Cylindrical pins are each engaged by a corresponding one of a plurality of coil compression springs for biasing the pin outward from the recess against said fixed surface for holding the ratchet wheel against rotation in a direction opposite the driven direction of rotation.

Abstract: A technique and system of intensity noise suppression is disclosed using delayed differential noise cancellation, which can be applied to external modulation links. This technique is particularly suited to external modulation links using semiconductor diode laser sources, but is not limited to this type of laser. Laser sources also can be followed with an optical amplifier to increase the optical power, which also adds intensity noise. In this noise cancellation method, the intensity noise can be generated by the laser or the optical amplifier, or a combination of both. A bandpass differential method is disclosed which cancels optical intensity noise like the conventional differential method but operates only over a narrow RF bandwidth. Here the two complementary output signals of the modulator are subtracted by delaying one output by half of the modulation period (180° or an odd multiple thereof) and then summing the optical signals.

The first stage has an expansion ratio greater than or equal to one and the second stage has a compression ratio greater than or equal to one. However, that the pressure at the second stage exit is less than the pressure at the first stage inlet.

Abstract: A method of packaging liquid detergent or fabric softener for single load use comprising thermoforming a container from a thermoplastic material such as polypropylene, polyethylene, polystyrene and the like, to a size sufficient to contain a 3-4 ounce amount of liquid detergent in a well thereof. The container comprises an open well with a peripheral lip an open end thereof. A printed foil strip, sized to cover the opening and at least a full circumferential portion of the container lip is heat sealed to the thermoplastic after the detergent is disposed therein. The foil and heat seal are of sufficient strength to retain the 3-4 ounces of liquid detergent even in an obverted position with jostling such as drug transport. Because of the heat seal, the container is not reclosable and storable and the full contents must be used once the container is opened, i.e., for a single use.
