Abstract: ABSTRACT OF THE DISCLOSURE         SYSTEM FOR REGULATING DATA TRANSFER OPERATIONS        A Magnetic Tape Peripheral Controller is used to manage data transfers between a peripheral tape unit and a main host computer. A buffer memory in the peripheral controller is provided with a status counter unit to monitor the amount of data-in-transit which momentarily resides in the buffer. The status counter unit provides output signals to the peripheral-controller to elicit action calling for more date from the peripheral tape unit or from the host computer or to indicate that the amount of data in the buffer memory was fully loaded before the main host computer responded to allow acceptance of it.

Abstract: Abstract of the Disclosure A molding apparatus  (10) has first and second opposed mold surfaces (22, 26) with the first mold surface (22) having a feed runner network (24). A mold structure  (30) is supported by the second mold surface (26) and is spaced from the first mold surface (22).  The mold structure (30) is adapted to hold a lead frame strip (38) and objects (39) held thereby in a plurality of openings (36).  A gate plate (44) fits between the first mold surface (22) and the mold structure (30).  The gate plate (44) has a plurality of gates or apertures (50) from a first  (46)  to a second  (48)  outfacing surface portion (46, 48) thereof.  Set feed runners (71) can be removed from the molding apparatus  (10)  by motivating the gate plate (44) laterally across the mold structure  (30).   The runners are generally removed from the gate plate (44) by bending the gate plate (44) over a cylindrical surface (61) of small enough radius so that the set runners (71) cannot follow and are forced to separate gradually from the gate plate (44), eventually becoming completely free and falling away from the molding apparatus (10). The apparatus  (10)  is particularly adapted for automation and allows more molding cycles per unit time and wastes less encapsulating material than does prior apparatus.  A molding method utilizing the gate plate (44) is likewise set forth.

Abstract: ABSTRACT         The device delivers the elements in packs, to a verti-cally movable horizontal table (7), from where they are trans-ported above the pallet, plate or loading support (3) and layed down.  The table (7) has vertically movable motorized rollers (9) interspaced by a row of thin horizontal forks (20) arranged in an overhanging manner on the support (21) and movable both vertically and parallel to the motorized rollers (9). The packs of elements are stripped from the retracting forks by a comb means (33) which also helps to align the stack during the retracting of the forks (20). The device is useful for stacking piles of cardboard blanks.

Abstract: ABSTRACT           A clamp for drilling tubulars such as drill pipes includes a jaw which defines a cylindrical recess. A cylindrical insert is rotatably mounted within the recess.  This insert defines a cylindrically symmetrical toothed surface positioned to grip and frictionally en-gage the clamped tubular, and a cylindrically convex positioning surface configured to cooperate with the cylindrical recess to hold the insert in place in the jaw.  The insert is mounted in the jaw so as to rotate freely within a selected range of rotational positions in order to allow the insert to orient itself as neces-sary to maximize the area of contact between the insert and the clamped tubular over a range of tubular diameters. The insert is reversible in the recess so as to allow the insert to be positioned in the jaw as necessary to maximize frictional engagement with the clamped tubular in a selected direction of rotation. In one preferred embodiment, the toothed surface is provided with an array of asymmetrical teeth which grip the clamped tubular. Also, locking bars are provided on the jaw which co-operate with recesses in the ends of the insert to restrict the rotational movement of the insert within the recess.  Alternate embodiments of the insert employ cylindrically convex, cylindrically concave, or planar toothed surfaces.

Abstract: ABSTRACT OF THE DISCLOSURE      A valve for automatically charging water into a sewer line trap from a water line containing water under variable pressure comprises a case having a longitudinal bore and means for connecting the case in series flow in the water line.  A hollow shaft is mounted in the case and extends from the down-stream portion a predetermined distance toward the upstream portion thereof.  A piston slidably mounted on the shaft divides the bore of the case into an air chamber downstream of the piston and a water chamber upstream.  A floating seal is mounted within the water chamber upstream of the piston and hollow shaft.  The seal is advanced and retracted with fluctuations of water pressure in the water line.  In its retracted position it charges the water chamber with water and compresses the air in the air chamber.          In its advanced position, it discharges the water content of the water chamber into the trap, thereby maintaining the water level thereof.
