Abstract: Title of the Invention TICKET VENDING HEAD     Abstract of the Disclosure A ticket dispensing head for delivering individual tickets from a string of tickets connected by laterally extending lines of ticket material weakness in which tickets are advanced along a generally linear path past a breaker blade toward a limit switch adjustably positioned in the path of movement of the tickets beyond the breaker blade by a distance slightly greater than the length of a ticket with actuation of the switch interrupting the ticket drive to position the line of weakness connecting the leading ticket to the next ticket just beyond the blade breaker edge to permit a folder to fold the ticket along the so positioned line over the blade breaker edge for severing of the first ticket precisely along said positioned line upon subsequent actuation of the breaker blade to move along a path generally parallel to the ticket path.  The position of the switch is adjusted to accommodate tickets of different size.

Abstract: AUTOMATIC GAUGE CONTROL IN TANDEM STRIP MILLS                ABSTRACT OF THE DISCLOSURE      A method and apparatus for automatically controlling the gauge of metal strip rolled in a tandem strip mill.  Load cells installed on a first stand generate signals represen-tative of changes in the roll-separating force, and hence of gap error, at this stand.  Such signals are fed-forward, with a delay to allow for transport time of the strip minus screw-reaction time, to a second stand to effect screw adjustment of the latter.  Signals representative of gap error at the second stand, corrected for changes in the position of the screws at the second stand, are fed-forward to effect screw adjustment at a third stand, etc.  The screws of the first stand are maintained at their original setting, while adjustments in the screws of succeeding stands made in response to changes in the roll-separating force are effected exclusively by signals fed-forward from a preceding stand.      The invention also includes an improved method and apparatus for delaying transmission of analog signals for controlled intervals without need for converting the analog signals to digital signals.

Abstract: CONTROLLABLE INLET HEADER PARTITIONING            Abstract of the Disclosure An improved reheater for a moisture separator reheater includes an inlet header, an outlet header and a plurality of heat-exchange tubes connected therebetween. The inlet header is partitioned to provide at least two separate sections.  Piping and control valves are also provided to supply steam to each section of the inlet header from the reheater inlet pipe.  The improved reheater includes at least one bundle of tubes communicating with the header(s) via tubesheet(s).  The inlet ends of the tubes may be differentially orificed whereby in combination with a nominal flow rate to the partitions, in-tube condensate subcooling is substantially eliminated with minimal scavenging steam at design conditions.  At off-design, or low power level, conditions, where fixed resistances of orifices and fixed partitions cannot accommodate changes in heat transfer demand from tube to tube, the aforementioned control valves are automatically adjusted.  This invention effects a controllable inlet header partition resulting in minimal scavenging steam required to substantially eliminate condensate subcooling across the turbine load range.

Abstract: RETRACTABLE BOARDING LADDER     Abstract of the Disclosure A boarding stairway moves relative to fixed structure in front of it between a raised retracted position and a lowered operative position.  Rollers at the top of the stairway are guided in a fixed track that is straight and vertical along most of its length from its top but curves into a short downwardly-rearwardly inclined bottom section.          The stringers of the stairway rest against a roller rotatable on a fixed horizontal axis that is below and to the rear of the track; hence the bottom of the stairway swings rearward as it moves down.  A counterweight that moves vertically is connected with the stairway by a cable that has a vertical front stretch extending up from the counterweight to a cable guide above the stairway and a rear oblique stretch extending down from the guide to a connection on the stairway that is spaced  below its top.  As the stairway moves up and down, the inclination of the rear cable stretch so changes that the stairway can be manually started from each position towards the other and moves to the destination position by momentum, coming to a gradual stop at the destination position.

Abstract: TILT COMPENSATING HANGER FOR TOILET TANK DISPENSING APPARATUS                    Robert S. Dirksing ABSTRACT      A hanger for supporting a toilet tank chemical dispensing apparatus which attaches to the top edge of the tank and which incorporates a tilt compensating feature to accommodate non-vertical toilet tank walls. The dispenser is preferably so mounted on the inner leg of a generally U-shaped hanger which contacts the inner-most surface of the toilet tank wall as to be vertically adjustable.  The outer leg of the hanger contacts the outermost surface of the toilet tank wall at a pivot point.  Resilient means, which direct a force between the inner leg and the inside surface of the toilet tank wall at a point above the pivot point, coact with the pivot point to produce a coupled force system.  The coupled force system causes the hanger and dispenser adjustably secured thereto to rotate about the pivot point into a position in which the lowermost end of the dispenser is held adjacent the tank wall, thereby maintaining the dispenser as close to vertical as is feasible despite the tilt inherent in the toilet tank wall.

Abstract: ABSTRACT         An assembly for a catalytic converter includes a housing and a catalyst-supporting substrate, or monolith. The housing includes upper and lower halves.  One of the housing halves includes an enlarged perimetrally extending lip region.  The other housing half includes a perimetrally extending insertion portion for insertion into engagement with the lip region.  The housing halves are compression-loaded one within the other to either a predetermined force or a predetermined depth of insertion.  This shoebox-like assembly is fabricated by supporting the lower housing half on a perimetrally extending ridge formed in the lower housing half and applying force to a perimetrally extending ridge formed in the upper housing half until the predetermined force has been reached or the insertion portion has reached a predetermined depth of insertion within the lip region.  The assembly is compact and utilizes a minimum of space on a vehicle.
