The invention relates to ACSR conductors having two or more layers of conductor strands wound helically around a steel core, the layers being wound alternately in right-handed and left-handed helices. The AC/DC resistance ratio of such a conductor can be greatly reduced by appropriate selection of the lay factors of the strand layers in relation to the cross sectional areas of the respective layers. The unbalanced mechanical torque can also be greatly reduced by appropriate selection of the lay ...

A low friction, low wear coating paint for rubber comprises polyurethane enamel filled with between about 20-40 wt. % amorphous flake graphite.

A low emissivity, low shading coefficient, low reflectance window consisting of two panes of glass. The first pane having a low wave infrared reflecting and a visible light and short wave infrared absorbing section of coatings on its inside surface. A second pane spaced about one half inch from the inside surface of the first pane to protect the coatings on the first pane and to insulate the room form the heat generated on the light and heat absorbing coating of the first pane. The infrared refl...

A lounging chair usually has a high back extending upwardly from a seat so as to be engaged by the shoulders and head of an occupant when reclining in the chair. Such a high back on a chair usually does not fit well in a room having low backs on the davenport, setees, chairs and like. The present invention pertains to a lounging chair which has a low hollow back in which an extensible back section is pivotally mounted for swinging movement rearwardly, upwardly and forwardly in extension of the t...

A low drain pulse generator which can be used in, for example, apparatus for measuring temperature differences in a flowing fluid includes a pair of monostable flip-flops connected in cascade to a mechanically actuated switch which yield sequential pulses when the switch is actuated. The outputs of the monostable flip-flops are connected to inputs of a pulse generating circuit which transmits a bipolar pulse signal to its output upon receipt of the sequential pulses from the monostable flip-flop...

The cutting rotor of a low noise level chipper is closely confined within a housing and yet is provided with a series of air escape passages through the body of the rotor so that air which is otherwise trapped within the close confines of the housing and acted upon by the rotor to produce piercing noise is instead released through the rotor itself during rotation thereof whereby to preclude the emission of such noise. A number of generally rectangular blocks are spaced apart along the axle shaft...

The low profile scale assembly includes a scale platform, a scale base unit, a load sensing means mounted on the scale base unit, and a parallelogram flexure linkage between the scale platform and base unit for applying vertical load forces to the sensing means. This flexure linkage includes first and second spaced, horizontally coplanar parallel elongated beams, the first beam being connected to the scale base unit and the second beam being connected to the scale platform. Upper and lower paral...

The purposes of this invention, namely preventing the molten metal from solidifying in the casting tube and manifold of a low-pressure chill-mold casting installation and avoiding any undesired contact between the molten metal and the external air, are achieved by providing a novel structure of the end of the casting tube, wherein said end is connected to a cover of which one opening is coincident with a casting inlet of the mold, said cover being fitted in a corresponding cavity of the chill-mo...

A low cost sealed electrical connector in which the mating plug and receptacle connector members are each formed of a unitary body of elastic pliant molded material in which mating contacts are mounted in aligned contact passages. The receptacle connector member is formed with a resiliently radially expandable sleeve which slidably receives a forwardly extending annular section of the plug connector member. Such annular section defines a cavity which slidably receives a central projection formed...

A method is provided for metallizing a ferrite at low temperatures. The method includes depositing a layer of lead on the ferrite, coating the lead layer with titanium hydride, distributing lead solder upon the titanium hydride, heating the ferrite until the lead solder flows uniformly over the lead layer, and slowly cooling the ferrite.
