Abstract: COLUMN MOUNTED SWITCH FOR VEHICLES AND THE LIKE     Inventor:  Arnold A. Breviek ABSTRACT OF THE DISCLOSURE An improved column mounted switch for vehicles and the like for controlling the windshield wipers and the windshield washer in an automobile or truck.  One or more rotatable carriers are in electrical contact with a base member having electrical conductors.  The rotatable carriers also have conductive member means which can enter into and pass out of electrically conductive relation with the electrical conductors to act as a switch having multi-ple functions.  The carrier may comprise shaped portions of a conductive metal plate, with the shaped portions being embedded in an insulating plastic disc.  Thus the shaped portions form a part of the smooth face of the disc which can smoothly rotate in contact with the electrical conductors of the base, while an added contact may be provided to the carrier by means of a conductive ring, as part of the con-ductive metal plate, exposed to the other side of the carrier for contact with other conductive member means.  The design of this application permits the elimination of one carrier and cover, when compared with switches of the prior art having similar functions.

Abstract: ABSTRACT OF THE DISCLOSURE                A electronic wattmeter in the form of an electronic watt-transducer circuit requiring a minimum number of components that can be fabricated by monolithic semiconductor integrated circuit manufacturing techniques and which provides a direct current output signal that is proportional to watt.  The electronic watt transducer circuit comprises a first transformer for developing a voltage related signal proportional to the input voltage to be measured and a second current transformer for developing a current related signal proportional to the input current to be measured.  A pulse width modulator is connected to receive the voltage related signal and an input repetitive sampling signal for producing repetitive pulse width modulated output having instantaneous pulse width proportional to the corresponding instantaneous amplitude of the voltage related signal.  Double-pole, double-throw electronic switch multipliers are connected to be automatically switched in response to the repetitive pulse width modulated output signal to develop at the output thereof alternating polarity, pulse width and amplitude modulated signal pulses having instantaneous pulse widths proportional to the voltage releated signal and instan-taneous amplitudes proportional to the current related signal, and a DC component proportional to the product of the two and hence to the power consumption represented by the electric voltage and current being monitored.  An averaging type current-to-current converter is connected to the output from the electronic switch multiplier for providing an output analog average direct current electric signal proportional to watts.

Abstract: GEL ELECTRODE FOR          EARLY DETECTION OF METAL FATIGUE          Abstract of the Disclosure Early fatigue damage in aluminum is assessed by detection of microcracks in an anodized surface film using a hand-held electrode having a contact tip formed of a gel containing an iodide salt and starch.  The gel tip is pressed against the anodized film and an electrical pulse is applied to pass current through the microcracks to oxidize iodide in the gel to form black iodine-starch complex.          Thus, dark spots in the gel indicate the sites of fatigue-induced microcracks in the oxide and thus the extent of fatigue damage in the metal.

Abstract: ABSTRACT OF THE DISCLOSURE   A method of making pneumatic tires substantially reduces or eliminates sidewall indentations in the inflated tire.  A plurality of cuts is made in one end of each layer of ply fabric where the end of the ply fabric overlaps the other end to fonm a splice which results in the generally annular shape of the ply layer.  The cuts extend in a direction generally transverse to the end edge and preferably have a length which is approximately the same as the width of the overlap of the cut edge with the other edge.  the cuts prevent overtensioning of the ply cords, which otherwise result in sidewall indentations.

At least said second payout roll is mounted to the payout roll shaft through an overrunning clutch.  When the one end of the paper sheet being taken out is contacted with the slippery surface of the first payout roll, the sheet is extracted by the extracting rolls at a constant speed equal to the speed of the extracting rolls and thus without being affected by the peripheral speed of the feed-out roll assembly.

Abstract: ABSTRACT               SINGLE-ENDED RADIANT TUBE    To reduce heat transfer to the flame tube 2 adjacent to the burner 5, vanes 19 are associated with the burner which cause combustion air to swirl before it mixes with gas from the burner and produce a vortex which encourages the gas to flow, and the flame to extend, centrally of the flame tube adjacent to the burner, and also cause air to surround the flame adjacent to the burner.   In one embodiment the air is divided by a cowl 23 into a primary stream which passes through the vanes and a secondary stream which passes over the cowl and surrounds the flame adjacent to the burner.  By means of an air shroud 23 the air is caused to converge towards the central axis of the flame tube as it approaches the vanes. The flame length can be  varied by  adjusting  the  distance  between  the shroud and the burner.

Abstract: Abstract Air operated material handling equipment moves con-tainers having elongated longitudinal axes from a mass in a bulk storage zone, wherein the longitudinal axes are disposed vertically and in side-by-side relation over a transport surface means having a prearranged pattern of floatation air jet openings in the surface slanted in a downstream direction.  The transport surface means is divided into a plurality of zones including a bulk storage zone and a single file zone with one or more intermediate transport zones therebetween.  The intermediate transfer zones have converging sides to move the containers from the bulk storage area into single file.  Jets of air are delivered by angularly-disposed floatation air jet openings to lift, support and to move the articles forward.  Additional acceleration jets of larger size accelerate the leading containers to separate them from the mass of containers in the intermediate transport zones to move them into single file.  The converging sides bring the forward portion of the mass into an equilateral configuration and cooperate with the acceleration jets to move them subsequently into isosceles triangular configurations with an ever increas-ing base length and finally into single file.
