Abstract: Abstract of the Disclosure A unit set or assembly of multiple plies includes superimposed top, intermediate and bottom plies as well as a cover ply disposed over the top ply. A flap is removably connected to this cover ply along the line of weakening and underlies the bottom ply.  First and second axially aligned holes of dif-ferent sizes are respectively provided in the bottom and intermediate plies, the size of the bottom ply holes being less than the size of the intermediate ply holes.  Adhesive is provided on the flap for securing the top ply thereto, such adhesive extending through the intermediate ply holes.  The size differ-ence between the axially aligned holes defines portions of the bottom ply which serve to mask the intermediate ply holes so as to confine the cross-sectional size of the adhesive, which extends therethrough, to the smaller size of the bottom ply holes.  Accordingly, the cover ply may be removed from the set while leaving the remaining plies intact, and separation of the top and bottom plies breaks the adhesive and frees the intermediate ply.  Thus, a multiply set is provided without the need for a removable stub thereby resulting in paper sav-ings and avoiding the need for stub handling and disposal.

Abstract: METHOD FOR PLACEMENT OF             PRODUCTION CASING UNDER OBSTACLE                  Abstract of the Disclosure A system and method of installing a production casing along an inverted underground arcuate path beneath and spanning an obstacle such as a river is disclosed.  The casing is installed along the inverted arcuate path of a pilot string occupying a pilot hole underlying the obstacle.  The pilot hole spans the obstacle from a first position at or near ground level on one side of the obstacle to a second position at or near ground level on the other side.  An oversized casing having an inner diameter greater than the outer diameter of the production casing is first advanced into and partially along the pilot hole from one side of the obstacle.  The oversized casing is advanced along the path of the pilot hole until it becomes frozen in place or is substantially impeded typically by friction.  The produc-tion casing is then advanced through the interior of the oversized casing along the extent of the path of the pilot hole occupied by the oversized casing and along the remainder of the path of the pilot hole to the other side of the obstacle.  If desired, second oversized casing can be advanced into and partially long the path of the pilot hole from the other side of the obstacle as well.  When extremely wide obstacles are to be traversed, it may be desirable in addition to advance secondary oversized casings inside the initial oversized casings and along the path of the pilot hole until they too are substantially impeded by friction.  In this manner, the production casing can be installed beneath and spanning extremely wide obstacles.

Abstract: Title of the Invention:     ELECTRONIC RAILROAD TRACK                    MARKER SYSTEM           Inventor:  Richard H. Noens ABSTRACT OF THE DISCLOSURE      A locomotive is fitted with a transmit and a receive coil.  Resonant circuits are packaged within a housing that is secured at a preselected point along a railroad track to serve as a position marker.  When the locomotive passes the marker, a signal is coupled from the transmit coil in the locomotive to the marker resonant circuit and back to the receiver coil in the locomotive.  Discrimination circuitry is connected to the receive coil for ensuring that the received signal has a minimum amplitude and a particular phase relation-ship with the signal in the transmit coil.  Further, the received signal must maintain these amplitude and phase relationships for a preselected count.  Upon proper discrimination, a "mark" signal is generated to an event recorder on board the locomotive.

Abstract: WINCH VALVE DRAG BRAKE CONTROL     A B S T R A CT        A winch has a powered rotatable drum for winding in and releasing a cable, and the drum is driven and controlled by fluid pressure operated clutches and brakes.  A one-way clutch is associated with the brake and allows said drum to rotate in a reel-in direction when said brake is engaged.  An auxiliary brake is provided for stopping reel-in rotation of said drum caused by viscous drag of hydraulic fluid on the drive means when a valving element is in the Brake-On position.  A fluid flow directing system is located intermediate a winch lubricating system and the auxiliary drag brake.  It directs fluid flow from the winch lubricating system to the auxiliary drag brake responsive to shifting of the valving element to a Brake-On position, and blocks the fluid flow from the winch lubricating system to the auxiliary drag brake responsive to shifting of the valving element to any Brake-Off, Reel-In or Free-Spool positions.

Abstract: MICRO-COMPUTER AND PROGRAMMER FOR APPLICATION OF TIRE TREAD MATERIAL                       ABSTRACT      The invention relates to the formation of a tire tread profile by the application of rubber tread material upon a tire casing by employing a micro-computer programmer in conjunction with a tread material applicator apparatus.  The control system employed during tread formation uses a programmer having a micro-computer unit, a floppy disc and a keyboard, interfaced with a tread material application apparatus.      In operation, the programmer is connected to a drive motor of the tire tread application assembly and operates under the control of a tire profile program stored in the floppy disk.  Proper tread profile shape is arrived at as a function of the digital ratio between the actual position of the tire rotation and the transverse position of the tire tread applicator assembly.  The latter is di-gitally controlled within the parameters of a pre-programmed set of commands, as a direct and sole function of the position of the tire casing about its spin axis.
