Abstract: First and second foot pedal actuated drums are disposed adjacent each other.  Each drum is provided with a horizontal shaft having a drum beater secured thereto and extending at right angles, the beater being disposed adjacent a drum head.  Flexible resilient spring devices interconnect adjacent ends of the two shafts whereby actuation of the foot pedal of one drum causes the one drum to sound while the other drum is caused to sound without actuation of its foot pedal.

Abstract: INVENTORS:   OTTO LANZ and MICHAEL VITINS           INVENTION:  PROCESS AND APPARATUS FOR LOCATING FAULTS ON              A LINE             ABSTRACT OF THE DISCLOSURE                  A process and apparatus for locating faults on a line, wherein at least one signal (travelling-wave signal) associated with a travelling wave on the line and corresponding to the temporal progression thereof at the measuring location is formed from the voltage and current at a measuring location.      There are formed travelling-wave signals corresponding in number to the phases or conductors in the line and decoupled from one another in relation to the line inductances and line capacitances.  At least two time-integrals are formed with these travelling-wave signals or signals derived therefrom as integrands, each time integral being associated with one direction of wave-propagation on the line.  These time-integrals are processed by an evaluating function which characterises by way of its sign and magnitude the direction and distance of the fault from a predetermined reference location on the line, which function corresponds to a relationship prevailing at the fault location between the travelling waves proceeding in opposite directions on the line.

Abstract: BUS DOOR SWITCH APPARATUS              Abstract of the Disclosure Disclosed is a touch bar switch apparatus useful for the opening of bus doors and the like which may be included in an electro-pneumatic door-operating system of a vehicle. The apparatus includes an elongate touch bar and a pair of housings mounted for receiving the ends of the touch bar, and switch mechanism within at least one of the housings responsive to any lateral movement of the touch bar relative to a housing containing the switch mechanism. The electrical circuit closing of the mechanism involves, typically, a normally rectilinear, elongate, electrically-conductive coil spring extending along the neutral axis of the switching mechanism having its end portions fixed within an end portion of the touch bar and a portion of the housing in axially spaced relation therewith. The spring, functioning as a switch terminal, may be warped by lateral movement of the touch bar into contact with a normally concentric sleeve functioning as a switch terminal.

Abstract: TITLE:  BOTTLE CARTON                          Abstract of the Disclosure A carton for a group of capped bottles having sloping upper necks and cylindrical lower portions.  The carton is formed from a single molded blank.  It includes a rectangular top panel having an inner area slightly less than the composite area of the grouped bottles across their caps. Sloping side and end walls lead downwardly from the top panel to engage shoulders of the bottles at intermediate locations along their height in a horizontal plane.  The carton area across this intermediate plane is slightly less than the composite area of the lower portions of the grouped bottles.  The carton is applied over the grouped bottles, initially spread-ing the lower bottle ends because of the restricted area within which the caps are confined.  As the carton is closed, the lower bottle portions are pressed slightly toward one another.  The yieldability of the carton material at its corner areas assures production of a tight package with-out interior partitions for safe shipping of bottles.

Abstract: ABSTRACT OF THE DISCLOSURE          A slack adjuster for a cam-actuated vehicle brake that automatically compensates for lining wear of the brake shoes, wherein the slack adjuster is capable of differentiating between that portion of an actuating piston stroke required to take up the running clearance between the brake shoes and brake drum from the non-braking to the braking position and that portion or the piston stroke required for the naturally occurring lining wear of the brake shoes during use.  The slack adjuster includes a lever and housing rotated by the actuating piston and positioned on a cam shaft carrying an S-shaped cam for actuation of the brake shoes,  A worm gear is positioned on the cam shaft and a worm shaft carries a worm engaging the worm gear and supports an actuator or driving member for the shaft, a one-way spring clutch encompasses the actuator and worm shaft, and a linkage assembly located between the power source and the actuator acts to rotate the worm and thereby adjust the vehicle brake during the brake releasing stroke of the actuating piston, only where there is a greater braking stroke than that required to close the running clearance between the brake shoes and the brake drum'

Abstract: Abstract of the Disclosure An adiabatic reaction calorimeter useful for measuring the heat energy of a chemical reaction is dis-closed.  The calorimeter includes a bomb vessel which is thermally isolated within a sealed chamber.  The chamber, which is filled with a gaseous atmosphere, is defined within a box structure fabricated of an insulating material.          An auxiliary vessel is positioned in the chamber adjacent to the bomb vessel and is connected to the bomb vessel by a transfer conduit.  Temperature sensing means and heating means under the control of a temperature control unit are provided to control the temperature of the atmosphere to correspond to the temperature of the bomb vessel during the chemical reaction in the bomb vessel.  A differential tem-perature range is determined by measuring the steady state temperature before a chemical reaction and the final tem-perature at the completion of the reaction.  The differential temperature range is translated into units of energy corres-ponding to the energy of the chemical reaction.         The adiabatic reaction calorimeter is useful in obtaining extremely accurate measurements of the energy of exothermic or endothermic chemical reactions.

Abstract: ABSTRACT OF THE DISCLOSURE        The operation of a demethanizer being used to cryogenically separate high carbon dioxide content hydrocarbon feed into liquid ethane essentially free of both methane and carbon dioxide with simultaneous production of overhead gas comprising methane and carbon dioxide without carbon dioxide icing to foul equipment by virtue of maintaining pressure at which non-gaseous carbon dioxide remains dissolved in liquid hydro-carbon, can be improved by intentionally injecting a dehydrated methane-rich stripping gas to the bottom of the demethanizer. At temperatures below about -80°F, the addition of a stream such as dehydrated inlet gas stabilized the demethanizer operation by making the carbon dioxide to ethane ratio of the liquid bottoms product less sensitive to temperature flucuations in the reboiler system heating the bottoms. In this manner, product recovery is increased while acceptable carbon dioxide as well as methane content can be maintained. Such a method is compatible with closed-loop control of the reboiler temperature based on gas chromatog-raphy measurements.
