Abstract: METHOD OF VENTING HYDROGEN FROM A BIPOLAR ELECTROLYZER                      Abstract of the Disclosure Disclosed is a method of conducting electrolysis in a bipolar electrolyzer.  According to the disclosed method an electrical current is passed from anodes of a first electrolytic cell through an electrolyte to cathodes of the first electrolytic cell, evolving hydrogen at the cathodes.  The electrical current then passes from the cathode of the cell through a bipolar unit to the anodes of a subsequent cell in the electrolyzer.  The disclosed method is characterized in that the electrical current passes from the cathodes of the first cell through the bipolar unit to the anodes of the subsequent cell by first changing direction and passing laterally through a cathodic element of the backplate to conductor means between the cells, thereafter changing direction and passing through the conductor means, and then changing direction and passing laterally through the anodic element of the backplate to the anodes of the subsequent cell.  Also disclosed is a bipolar electrolyzer containing a plurality of individual electrolytic cells electrically and mechanically in series.  Each of the cells have anodes and cathodes, with the cathodes of one cell being separated from the anodes of the next adjacent cell in the electrolyzer by a backplate.  The electrolyzer is characterized in that the backplate has separate anodic and cathodic members with the anodic and cathodic members being spaced from each other, and conductor means which are offset from both the anodes and the cathodes of the cell.  In this way the electrical current changes direction four times, i.e., the electrical current must pass from the cathodes of the first cell laterally thereto, to conductor means and then from the con-ductor means, laterally thereto, to the anodes of the subsequent cell in the electrolyzer.

Abstract: CURRENT LIMITING CIRCUIT BREAKER                     Abstract of the Disclosure A current limiting circuit breaker having for each pole, a pair of main contacts separable upon operation of a thermally and electromagnetically operable tripping device and a pair of auxil-iary contacts for current limiting in series with the main contacts and in parallel with a transformable resistor having a positive temperature coefficient of resistance.  The auxiliary contacts are separable when an electromagnet is energized by a fault current which simultaneously energizes a field magnet to produce a trans-verse magnetic field across the auxiliary contacts and the arc formed between them when separating.  This simultaneous action of electromagnet and field magnet coacting for rapid contact separ-ation and lengthening of the arc upon flow of a fault current serves to increase arc voltage almost instantaneously to that of the source, about which time the fault current is totally shunted into the resistor.  The auxiliary contacts are carried on a pair of minimum inertia movable contact blades to facilitate rapid separation of the auxiliary contacts. The minimum inertia contact blades are elongated between a pivot point and the point at which the contacts are mounted, where they terminate without providing an arc runner portion.

Abstract: ABSTRACT OF THE DISCLOSURE         A frame extending around an opening in a vehicle roof is adapted to support the perimeter of a curved glass panel to close off the opening.  A pair of bayonets projecting in spaced relation to the underside of the forward edge of the panel mates with an aperture in the frame when the panel is inclined with respect to the roof to act as a pivotable hinge allowing motion of the panel between a closed position and that inclined position.  A two part fastener for the rear edge of the panel includes a handle pivotably connected to the underside of the panel and a tongue pivotably connected to the handle and adapted to be retained in a lock member in the frame.  The handle acts as an over-center linkage to bend the panel against its curva-ture, forcing its perimeter into intimate engagement with the frame or may be extended to maintain the panel with its rear edge tilted upwardly away from the opening.

Abstract: AUTOMATIC CURRENCY IDENTIFICATION SYSTEM     Abstract Of The Disclosure A method and apparatus for automatically identifying paper currency, stocks, stamps, and the like, by optically examining and viewing regions on the currency.  The graphic pattern scanned is stored as signal information and then compared with signals representing predetermined standard information on the pattern of the currency.  An identification is obtained upon the concurrence of a predetermined amount of the two information signals being compared.  The system can accommodate lateral shifts of the currency and skew angles of arrival of the currency, and still provides a suitable identification.  In the case of lateral shifts, it can either compensate for the shift or provide comparisons with a plurality of standard information signs, each for a different lateral displacement.  In the case of the skew angle, it can compare the scanned information with a stored file of different patterns, each representing a different skew angle, or can use statistical mathematics to provide a tentative identification which is then used to select a proper memory file.  The system can be used either to sort currency, or to identify a particular denomination while rejecting all other currency denominations.

Abstract: ABSTRACT OF THE DISCLOSURE               Novel organosilanes of a particularly recited struc-tural formula, i.e. (H2C=CHCH20)2  , in which R is selected from the group consisting of hydrogen and monovalent hydrocarbon radicals which are free of aliphatic multiple bonds, R2 is a bivalent hydrocarbon radical free of aliphatic multiple bonds, R3 is a monovalent hydrocarbon radical having from 1 to 8 carbon atoms and is free of aliphatic multiple bonds, R4 is selected from the group consisting of monovalent hydrocarbon radicals having from 1 to 8 carbon atoms and mono-valent hydrocarbon radicals interrupted by at least one either oxygen atom and n is 0, 1 or 2, and processes for preparing and using the same are provided herein.  The process comprises re-acting a silane having an Si-bonded hydrogen atom and at least one hydrolyzable group and/or at least one group capable of being hydrolyzed more readily than the Si-bonded hydrogen atom with a particularly recited organic compound having more than one double bond, namely of the formula  , in which R is selected from the group consisting of hydrogen and monovalent hydrocarbon radicals which are free of aliphatic multiple bonds, R2 is a bivalent hydrocarbon radical free of aliphatic multiple bonds, R3 is a monovalent hydrocarbon radical having from 1 to 8 carbon atoms and is free of aliphatic multiple bonds, R4 is selected from the group consisting of monovalent hydrocarbon radicals having from 1 to 8 carbon atoms and monovalent hydro-carbon radicals interrupted by at least one either oxygen atom and n is 0, 1 and 2, in the presence of a catalyst which pro-motes the addition of Si-bonded hydrogen atoms to aliphatic double bonds.  These organosilanes are used as reinforcing agents for providing cross-linked compositions containing or-ganic polymers which are cross-linked by means of sulfur, sul-fur compounds or peroxides.  The resultant cross-linked products exhibit greatly improved elogation at break, increased tensile strength and increased resistance to tear than could possibly have been obtained with the reinforcing agents known hereto-fore.  Thus, the products are useful as cable covers, trans-mission belts, conveyor belts, roller coverings, vehicle tire surfaces, shoe soles and gaskets.

Abstract: A B S T R A C T           This invention discloses a method and device for reducing fuel consumption by a locomotive system comprised of a plurality of tandem diesel locomotives electrically inter-connected so that one of the units is a lead unit and the re-maining units are trailing units.  In particular, the fuel saver arrangement of the present invention is capable of selectively placing one or more of the locomotives in the system in a "throttle one" power position without causing any significant reduction in the operating efficiency of the system's safety equipment.  The locomotive is placed in the throttle one power position by means of switching relays that are operable to override the normal throttle control circuit of the locomotive.  These relays respond to a fuel save signal that is generated in the control box located on the lead unit.          The control box includes a fuel save switch operable to initi-ate and terminate the fuel save operation and a unit selector switch operable to select the locomotive to be reduced in power.          Each locomotive within the system is also provided with a fuel saver setup switch which electrically interconnects all of the diesel units of the system.  The unit selector switch and the fuel saves setup switches are multiple position gang switches which operate in conjunction with each other to provide the fuel save signal to the proper locomotive to be reduced in power by means of the unused train line wires and jumper cables present in a normal locomotive system.
