Abstract: A stand suitable for elevated support of water heaters and similar objects is disclosed. The stand includes a planar, rectangular tabletop formed and stamped from sheet-like material, and being further formed with downwardly bent marginal side flanges. The tabletop is supported by two pairs of oppositely disposed leg members, which are also stamped from sheet-like material. Each leg member is formed with a longitudinally extending flat central portion and oppositely positioned coextensive angularly bent flange portions. The surface of each leg flange mates with an adjacent facing surface of a respective surface of a respective one of the downwardly depending tabletop flanges. The stand further includes a cruciform arrangement of overlapping crossbars.

Abstract: The novel stand described and claimed herein has been found to be suitable for elevated support of water heaters and similar objects. A preferred embodiment of the stand may comprise a planar, rectangular tabletop formed and stamped from sheet-like material, and is being further formed with downwardly bent marginal side flanges. The tabletop is preferably supported by two pairs of oppositely disposed leg members, which are also stamped from sheet-like material. Each leg member is formed with a longitudinally extending flat central portion and oppositely positioned coextensive angularly bent flange portions. The surface of each leg flange mates with an adjacent facing surface of a respective surface of a respective one of the downwardly depending tabletop flanges. The stand further includes a cruciform arrangement of overlapping crossbars, of which opposite end thereof include means for detachable securement to an oppositely disposed one of said pair of leg members.

Abstract: A rail mount having a mounting plate and bracket for supporting a flexible conduit, such as plastic or metal tubing. The mounting plate includes upturned, laterally spaced ear portions, each including an aperture for receiving a supporting rail or rails, the rail or rails being suspended between parallel rigid beams, such as floor joists or wall studs.

Abstract: A stationary support member providing a close bend to support a flexible conduit, such as plastic or metal tubing, and to rigidly mount the conduit on a support structure.

Abstract: Gas-condensate having an API gravity value greater than 55.degree. is produced by injecting (1) a light noncondensable gas and (2) a foaming agent comprising a surfactant and water into a subterranean formation containing the gas condensate.

Abstract: Ores of metal oxides and oxide-like compounds such as chromite and pyrochlore are beneficiated by froth flotation in the presence of substituted amino phosphonic acids or salts thereof.

Abstract: A stubout bar having notches instead of holes for holding plastic or metal pipes.

Abstract: A frequency modulated continuous wave radar wherein analog signals received from a target are converted to digital form, processed by correlation with differently delayed signals, also in digital form, of a modulation waveform repetitively applied to the transmitted signals and the frequency spectra of the resulting signals are determined, such spectra being indicative of range of the target. In addition, a digital correlator adapted to perform the desired correlation is shown.

Abstract: An arrangement is shown to process mainlobe echo signals and range sidelobe signals in the receiver of a pulse compression radar by first converting such signals to a set of digital numbers and then correlating, number by number, such set with a set of reference numbers describing the mainlobe echo signals and the negative of selected range sidelobe signals.

Abstract: A signal processor is disclosed wherein an intermediate frequency chirp pulse is pulse compressed and the linearly frequency modulated, intermediate frequency component of such compressed pulse is removed. With such an arrangement, various weighting techniques may be effectively used to reduce sidelobes of the compressed pulse while, in a radar system application, retaining the sense of the frequency of a Doppler shifted compressed pulse.

Abstract: Organotin esters from acid esters of di or poly carboxylic acids are made by mixing base an organotin halide and the acid ester in the presence of water, and reacting to form the organotin ester, the amount of base and acid ester being to provide 0.9-1.3 equivalents and at least 0.9 equivalents respectively per g. atom of halogen in the organotin halide, and the conditions being such as not to cause substantial hydrolysis, and the progressive mixing of base with organotin halide or acid ester being not later than the mixing of organotin halide and acid ester.

Abstract: A signal processor having a plurality of charge transfer devices adapted for coupling to an input signal source. Each one of such devices produces a sample of the input signal in response to a sampling signal. An input shift register having a plurality of serially coupled stages is provided, each one of such stages being coupled to a corresponding one of the charge transfer devices. Circuitry is included for enabling the sampling signal to be sequentially produced at an output of each one of the serially coupled stages, enabling sequential samples of the input signal to be produced in corresponding ones of the charge transfer devices.
