    摘要： A roller retainer for a cam actuated vehicle brake assembly comprising a member preferably formed from spring wire to provide two substantially parallel legs with a tang at the end of each leg and a manual grip intermediate the legs. The tangs are seated in apertures provided to a dual web brake shoe and a portion of the member intermediate the manual grip and the tanged ends extends only partially around the roller so the manual grip and the tanged ends are disposed on the same side of a reference plane parallel to the legs and passing through the axis of the roller. This enalbes the retainer to be rotated about the apertures thereby allowing the roller to be safely removed from the brake shoe while the shoe remains in the assembly without the use of any tools.

    摘要： An extruded polymeric void-board is configured for placement between adjacent horizontal layers of bricks to maintain an opening in a lower layer of the bricks. The void-board is formed as a relatively thin planar element having first and second surfaces. A plurality of parallel ribs extend from and generally transverse to the first side. The ribs have a predetermined height to width ratio and have a height that is less than a thickness of the planar element. The ribs being formed parallel to one another. A method for forming a bundle of bricks with the void-board is also disclosed.

    摘要： A system including method and apparatus for determining the energy content in a signal to be analyzed employs, in an apparatus aspect thereof, a sampling element for producing samples of the electrical signal to be analyzed, a local correlator for producing a plurality of signals corresponding to the samples delayed and multiplicatively combined with their complex conjugates, a bank of delay and adder systems for correlating the outputs of the multipliers in accordance with a binomial kernel, and a Fourier transformer for producing the distribution as a function of time and frequency. Local correlation is effected using a multi-element delay system, such as a shift register. Binomial correlation in the delay and adder systems is achieved by combining additively given samples with samples which are in other states of delay. Moreover, the banks have respectively different numbers of such delay and adder systems. The resulting analytic signal corresponds to a binomial kernel.
