Abstract: ABSTRACT OF THE DISCLOSURE            An improved material flow rail construction of the type employed to transmit containers or articles from one location to another gravity force. The improved material flow rail comprises a substantially U-shaped channel within which a multiplicity of mounting bolts are attached. Individual bearing assemblies are placed on the mounting bolts. By placing the individual bearing assemblies closely adjacent one another in a longitudinal direction with respect to the support channel, the flow rail has the ability to transmit parts having very small "footprint" areas since a large space between rollers is not presented  for  parts or  components  thereof  to become  caught.   By providing a loose fit between the bearing inner races and the supporting mounting bolts, the inner race is permitted to rotate slightly with respect to the mounting bolts thereby presenting new wear surface as the flow rail is put into use.  Additionally, such loose fit may be provided between the mounting bolts and the support channel to permit the latter to rotate with respect to the former, also presenting new wear surfaces.

Abstract: -12-                52,022 ABSTRACT         A tube support plate is disclosed for supporting a plurality of tubes with reduced vibration in a nuclear steam generator.  The support plate has a plurality of holes disposed therethrough in a regular array.  Each hole has an axis, an interior surface and a plurality of lands supported on the interior surface and extending towards the axis.  The support plate has a given thickness as taken along the hole axis, and each of the lands has a tapered surface for facilitating tube insertion.  The method of forming the tube support plate comprises a first step of forming each of the holes through the support plate with a first cylindrical portion of a first diameter and a second cylindrical portion of a second diameter less than the first diameter.  Next, portions of the second cylindrical portion are removed in a second step to form a plurality of lands having exposed ends supporting a tube within the hole.

Abstract: ABSTRACT OF THE DISCLOSURE     A method and apparatus for a microinstruction controlled unit  having  multiple  subunits  which  are controlled  by microoperations  encoded  within  microinstructions  from   a control store.  One master subunit controls the order in which the microinstructions are executed by generating the address of  the  next microinstruction  to  be  read  from  the  control store.    The  method  provides  for  the  overlapping  of  the execution  of  a  current  microinstruction  while  the  next microinstruction is being addressed and read from the control store.   The control store is divided into  control substores with  each  control  substore  located near  the  subunit which executes the microoperations stored in its associated control substore.   Subunits can affect the order of microinstruction execution by causing a trap in the master subunit which will cause the next microinstruction to be read from a predefined address within the  control  store.   If  required,  the master subunit can read in status information from the subunits in order  to  determine  the  condition within  the  subunits  that caused the trap to occur.   A means is provided for storing a return address which allows for execution to continue at the next microinstruction that would have executed had a trap not occurred.

Abstract: ABSTRACT     Improvements in or relating to cable joints.         A cable length of the type comprising a conductor, polymeric insulation 3 over the conductor, a semiconducting screen 4 over the polymeric insulation, a fault carrying screen 5 over the semiconducting screen, and a protective sheath 6 over the semiconducting screen has at least the leading end thereof partially prepared for jointing prior to laying of the cable.  At the or each such end the cable is stripped back over successive increasing lengths 7, 8, 9 to its polymeric insulation 3, its semiconducting screen 4 and its fault carrying screen 5.  A semiconducting sleeve 13 fits over the protective sheath 6, extends over the stripped lengths of fault carrying screen 5 and semiconduct-ing screen 4 and abuts the end portion of the latter.  A clamp 12 disposed within the sleeve 13 terminates the fault carrying screen 5 and a sleeve 19 of polymeric insulation is provided on the stripped length of polymeric insulation 3.  The sleeves 13 and 19 have the same outside diameter and the cable end has a generally cylindrical form with an outside diameter such as the outside diameter of the cable.  This facilitates laying of the cable when the end is the leading end and has to be pulled through a trench.

Abstract: A B S T R A C T            A method of manufacturing cards having an electronic memory, and cards obtained by performing said method.          In order to improve fixing between an electronic module (140) and the body (120) of a credit card made of plastic material, a housing (122, 134) is provided in the card body with bumps (130, 132) projecting into the housing.  The electronic module (140) is pressed against the bumps (130, 132) while being raised to the softening temperature of the material from which the bumps are made. The module is pressed until its contact tabs (148) are level with the face (126) of the body.  Fixing is completed by causing a glue to penetrate by capillarity between the bottom (124), the insulating substrate (142) of the electronic module, and the bumps (130, 132). The invention is particularly applicable to prepaid credit cards.

Abstract: Abstract of the Invention An agricultural planter has a main carrier frame attached to a tractor by an hydraulically actuated telescoping tongue.  Individual row units are mounted on a lift frame which in the illustrated embodiment has a center section and left and right wing sections. The wing sections are mounted to the center section for independent vertical pivotal motion relative to the center section in the use position.  Power locks secure the wings rigidly to the center section for road transport.  The lift frame is mounted to the carrier frame by a vertical pivot post and an hydraulically powered lift linkage.  The pivot post may be rotated by an hydraulic cylinder under control of the operator.  In the use position, the hitch tongue is retracted and the lift frame is lowered and extends transverse of the direction of travel.  For transport, the tongue is extended, the lift frame is made rigid, then elevated by a master/slave cylinder arrangement which powers the lift linkage to a transport height, and then the lift frame rotated so that it extends in the direction of travel.  The lift frame is then locked in that position for end-wise transport on the carrier frame.

Abstract: THERMAL PROTECTION ARRANGEMENT FOR SOLID DISK GLASS COOKTOP            ABSTRACT        A solid disk surface unit mounted in a glass ceramic support surface, comprising a plate member of cast material with one or more resistive heating elements mounted to the underside thereof and a thermally conductive cover member enclosing the underside of the plate member with its peripheral edge in close thermal contact with the plate member near its periphery, is provided with a thermally responsive switching device thermally coupled to the cover member and adapted to respond to the surface temperature of the cover member at a point relatively remote from its peripheral edge.  The switching device is operative to remove power from the resistive heating elements of the surface unit when the sensed cover member temperature exceeds a predetermined threshold temperature, thereby protecting the glass support surface from damage due to thermal stresses resulting from hot spots occurring near the periphery of the surface of the plate member.
