    摘要： A signaling apparatus that includes a transmitter having a step-square wave generator for generating a signaling waveform, which waveform is composed of a plurality of square wave signals, and which has an information signal encoded thereupon. The apparatus may also include a signaling waveform receiver, disposed on the railcar, and an information signal decoder, connected to the receiver, for extracting the information signal from the receiver. The stepped-square wave generator produces square waves such that a portion of the duty cycle of one of a plurality of square wave signals overlaps at least a portion of the duty cycle of at least one other of the plurality of square wave signals. A method for signaling in which a multi-stepped square waveform is generated, includes a waveform having a series of superimposed square waves, each of which having preselected amplitudes and duty cycles. An information signal can be encoded upon the multi-stepped carrier waveform such that a coded-carrier signal is created.

    摘要： Sheets or moulded bodies, for example particle board, are manufactured by hot pressing a lignocellulosic material in contact with an organic polyisocyanate and a wax release agent which is a vegetable wax, a modified vegetable oil, a microcrystalline wax or a mineral wax, said wax release agent having a melting point of at least 70.degree. C. Preferably the wax release agent is applied to the lignocellulosic material in the form of a dispersion in an aqueous emulsion of the polyisocyanate. The process facilitates the release of the sheets or moulded bodies from the caul plates or platens of the press.

    摘要： Certain oxaalkanoate zwitterionic surfactant-type compounds and their esters are not only excellent detergents, but also provide superior oral therapy for ulceration of the gastric mucosa. The oxaalkanoate zwitterionic compounds are especially preferred in the management of both gastric and duodenal ulcers.

    摘要： A mallet-style golf ball putter with a hollow pipe component that has generally the same diameter as a golf ball, is positioned about the sweet spot in the vertical and lateral dimensions on the putter striking face, and extends longitudinally towards the rear of the putter to assist the golfer to align the striking face of the putter with the golf ball when in an address position and with the intended line of putt during takeback and follow-through. Peripheral weighting further enhances the moment of inertia of the golf putter head. The pipe component so designed permits a visual alignment of the striking face with the golf ball in the lateral and vertical dimensions and for a smooth perpendicular stroke along an axis of the pipe.
