Abstract: A locking apparatus for releasably securing the lid of a trash container in a closed position has a locking arm with an elongate central portion and bent end portions pivotally mounted on opposite side walls of the container for movement between a first position in which the central portion extends across a front wall of the container and a second position in which the central portion extends over the lid to hold it closed. The central portion is initially adjustable in length to accommodate different size containers. The arm is lockable in both the first and the second position.

Abstract: A lid support assembly for a trash bin lid rod has a plurality of rod supports engaging the lid rod and secured to the rear wall of the bin to resist bending of the lid rod. An elongate lid prop has an opening for engaging over the lid rod with a first portion of the lid prop extending away from the opening in a first direction to provide a support for the trash bin lid in a partially open position, and a second portion extending in a second direction away from the first direction to engage the rear wall of the trash bin. Rod supports are positioned on opposite sides of the lid prop to secure the lid prop in the desired position on the lid rod.

Abstract: A low noise accurate signal generator for a calibration system or a radar system includes a generator of a digital data stream having a predetermined frequency spectrum incorporated therein. A series connected array of Josephson junctions is coupled to and excited by the digital data stream to provide a stream of pulses with quantum mechanically accurate time integral. A low pass analog signal filter is coupled to the pulses of accurate time integral for extracting analog signals of the predetermined frequency spectrum. For radar applications, a low phase-noise local oscillator of a fixed RF frequency and the output of the filter are coupled to a signal mixer which outputs low phase-noise chirped RF signals for use in generating transmit pulses for the radar system whereby enhanced detection of targets in "clutter" can be obtained.

Abstract: A caster holder includes an open frame and retainers for holding the plate of a caster at two ends. The open structure of the frame is economical and minimizes weight. The frame may be economically manufactured by bending a single strip of metal. The frame may be provided to the user in kit form for the user to weld to an object. The retainers may include a fixed rod or a lip at one end and a removable bolt at the other.
