Abstract: ABSTRACT OF THE DISCLOSURE      A package blank has successive portions which constitute the front wall, bottom, back wall, lid back wall, lid top surface and lid front wall, with side flaps which are overlapped in the completed package and form the side wall.  The side flaps adjacent the front wall, the lid front wall, and the lid top surface, and that are the outer overlapping side flaps in the completed package are made of a width corresponding to the width of the side wall of the completed package, while the innermost of the overlapping side flaps are made with a narrower width dimension, so that the blank has a wide part and a narrow part.  This reduces waste, as the blanks may be cut from packaging material in such manner that the narrow part of one blank is rested closely adjacent the wide part of an adjacent blank.

Abstract: Powers 2 METHOD OF MAKING OPTICAL WAVEGUIDES                   Abstract of the Disclosure A method of making low loss glass optical waveguides, wherein at least one coating of glass soot is deposited by the flame hydrolysis process on a starting member.  The starting member is removed from the coating material or glass soot preform leaving an aperture therein, and a tube is secured to one end of the preform.  While the preform is heated to its consolidation temperature, an atmosphere including a drying agent flows from the tube into the aperture and through the porous preform, thereby removing water from the preform while the soot is consolidated to form a dense glass article.  The tube can be removed, and the resultant dense glass article can be drawn into an optical waveguide fiber.

Abstract: ABSTRACT OF THE DISCLOSURE A dual cavity tire press having side by side mold sections incorporate vertically extending center mechanisms which include a shaping bladder. The center mechanisms are moved vertically after the press opens while the bladder is within the tire to strip the tire from the bottom mold sections. Vertical movement of the center mechanisms is obtained by a single floating horizontally disposed piston-cylinder assembly which is mounted at the front of the press outside of the base, each end of the piston-cylinder assembly being connected through a lever arrangement to move the respective bead lift posts of the center mechanisms vertically. When the piston-cylinder assembly is pressurized, its entire force is applied simultaneously to each center mechanism to move the same vertically and such force is maintained throughout the vertical height movement of both center mechanisms. By a removable stop or lock, one of the center mechanisms may be made inoperable without affecting the movement and operation of the other.

Abstract: Abstract of the Disclosure A fail-safe time delay circuit is provided to pro-duce an output a predetermined time, and no less than a predetermined time after an input stimulus.  The circuit includes a driving circuit for a pair of relays which are operated at slightly greater than 50% duty cycle and out of phase such that, except when the circuit is de-energized, at least one of the relays is always energized.  The con-tacts of the two relays are employed in a balanced voltage amplifier to produce a bi-polar signal, with the magnitude of both polarities increasing, with the time required for the increase to a defined threshold establishing the time delay.  A pair of threshold circuits are coupled to the output of the balanced voltage amplifier such that each threshold circuit (one responding to the positive portion, and the other the negative portion of the bi-polar output) is energized when the respective portion of the bi-polar signal is detected   to reach the associated threshold.  Each of the threshold circuits provides an input to a vital AND gate such that only when the excur-sion in the bi-polar signal exceeds the threshold of both threshold circuits will the vital AND gate produce an output to energize a load.

Abstract: TITLE:  PROSTHETIC URINARY SPHINCTER VALVE          INVENTOR: ROBERT H. REINICKE                   ABSTRACT         A device for controlling flow of fluid to and from a resilient inflatable cuff implanted about the urethra to control flow of urine therethrough   The device comprises a flexible bulb reservoir and a control unit that includes a manually operated valve that opens automatically when the bulb is squeezed to force fluid into the cuff for closing the urethra.  The control unit also includes a movable valve seat member having a relatively large area exposed to pressure of fluid in a chamber that is connected to the cuff and which moves to a position in which the valve member is unseated by an abutment when fluid pressure in the chamber exceeds a predetermined value to thereby relieve excess fluid pressure in the cuff.  The arrangement is such that the valve element is held closed against the seat member by the full differential in fluid pressures acting on both sides of the valve element until the seat member is moved away from the valve element to thus insure positive closing of the valve element until the seat member is moved out of engagement with the valve element by excess pressure differential.
