Abstract: ABSTRACT OF THE DISCLOSURE A bottle cap is disclosed having a tear tab cooperating with score lines extending across the top of the cap for manual removal of the cap from a bottle.  The score lines are located slightly spaced from the peri-pheral edge of the top of the cap and arranged at least partly around the periphery of the cap.  This arrangement of the score lines serves to obtain an easy removal of the cap from the bottle after the tearing operation and is moreover, in combination with the sealing element, effectively preventing any risk for corrosion along the score lines, which has been an inadequacy of the prior art.

Abstract: ABSTRACT OF DISCLOSURE     The subject invention involves a device for sensing the depth to which a worn railroad wheel must be machined in order to reclaim the wheel tread and flange contour. The device consists of an assembly of gaging elements mounted on a support block which is, in turn, mounted on a guide rail for radial movement into contact with the wheel tread.       The gaging elements include a flange edge contactor slidably mounted on the support block, a tread contactor slidably mounted on the flange edge contactor, and a flange contacting finger pivotally mounted to the tread contactor. In operation the assembly is moved radially toward the wheel until the wheel tread is contacted. The tread contactor thereafter retracts, causing the flange contacting finger to engage the gaging point on the wheel flange. Further, downward movement of the assembly causes the flange edge contactor to move into engagement with the wheel. Appropriate encoders are connected to the gage assembly to generate pulses which indicate the position of the flange edge and the new diameter to which the wheel is to be machined.

Abstract: ABSTRACT         A system for controlling the hydrogen/hydrocarbon mole ratio in a continuous hydrocarbon conversion process in which hydrogen is consumed in a catalytic reaction zone.          Applicable to processes in which the reaction zone effluent is separated to provide a liquid product phase and a hydro-gen-rich vaporous phase, a portion of the latter being recy-cled to the catalytic reaction zone, the control system af-fords improved overall operation in addition to increased catalyst activity and stability. Analyzers are utilized to monitor composition characteristics of the charge stock and liquid product, and the hydrogen concentration of the vapor-ous phase introduced into the reaction zone.  Representa-tive process output signals are transmitted to comparator/ computer means which compares the rate of change of the com-position characteristics and the hydrogen concentration, and generates additional, comparator output signals which are utilized within the control system for regulating the hydrogen/hydrocarbon mole ratio.

Abstract: Abstract of the Disclosure An input analog signal is converted to a digital output signal by an oversampled predictive DPCM coder which includes an n stage delay line in the feedback loop.  The n delay line outputs are weighted by coefficients ai...an selected according to the relationship   and then summed.  Alternatively, the feedback loop may comprise a chain of n integrators arranged so that the signal fed back to the comparator is the sum of single, double, triple...n order integration.  By so doing, the coder attenuates the signal power at the quantizer input while the attenuator coefficients are independent of the input signal statistics.           A similar technique may also be applied in an oversampled error feedback coder, which includes a feed-back loop having an n stage delay line.  Here again, the delay line outputs are weighted in accordance with the above relationship.  Alternatively, a chain of n integrators may be used in the coder input, and an identical chain employed in the feedback loop.  By so doing the coder attenuates the coding noise power in the signal band while the coder design is rendered independent of the quantizing error statistics.

Abstract: FIFTH WHEEL CONNECTION FOR A  TRACTOR-TRAILER COMBINATION            Abstract of the Disclosure A slip-proof connection provided between the tractor and trailer of a tractor-trailer combination for carrying the super-structure of a mobile crane.  The connection or mechanism com-prises a mounting assembly secured to the tractor bed, a mounting plate carried on the front portion of the trailer supporting the crane superstructure, and means for cooperatively interconnecting the two mechanisms to assure an interlocked connection therebetween.          The connecting mechanism comprises a positive interlock wherein a mounting post carried on the mounting plate on the tractor is received into a complementary opening provided in the mounting plate on the front end of the trailer, and a sleeve is then mounted on the mounting post and positively locked in position to hold the tractor and trailer locked together.  Although the combination does not provide for the quick disconnect of the tractor from the trailer as is common with typical fifth wheel designs, it does permit articulation of the tractor and trailer combination.  Further, means are provided in association with the connecting mechanism to permit oscillation of the tractor and trailer in multiple oscillatory modes.  Additionally, locking means are provided on the mounting assembly to retain multiple oscillatory modes for rough terrain movement and to lock out one of the oscillatory modes for highway travel.

Abstract: ABSTRACT OF THE DISCLOSURE    Discloses a device for spraying, using a pump rather than an aerosol can, a viscous non-stick liquid cooking preparat-tion  onto a heated cooking surface or griddle.  The cooking sur-face is heated to a temperature of substantially 385° - 400° F. A heat conducting stand has legs resting on the cooking surface which conducts heat to a heat conductive support plate at the top of the stand, and to which the container for the liquid to be sprayed is clamped.  The heated plate and legs warm bottle to the right temperature for warming the cooking preparation to a temperature at which the pump can spray it through a spray nozzle onto the cooking surface.      The device avoids aerosol cans, and permits heat derived from the heated cooking surface to reduce the viscosity of the liquid cooking preparation so as to permit spraying it onto the cooking surface.  This combination of parts and the operation thereof is entirely new.
