Abstract: ABSTRACT OF THE DISCLOSURE         This invention relates to an improved core ring gated injection molding system.  The valve pin has a tip portion which joins a larger diameter stem portion at a tapered shoulder and extends through the cavity into the mold platen on the other side.  The tip portion of the valve pin is substantially smaller in diameter than the gate through the cavity plate, thus providing for the flow of melt through the gate around it when the valve pin is in the retracted open position.          In the forward closed position, the tapered shoulder seats in the gate to provide a seal.  By providing for operation in reverse directions to previous core ring gated systems, this increases cooling to the mold platen in the closed position and decreases it in the open position.

Abstract: ABSTRACT OF THE DISCLOSURE           Apparatus for panoramic X-ray photography of the area of the dentition and the jaws, has a bearing part linearly movable in relation to a frame part, and a support arm rotatably attached by bearings to the bearing part, the arm having at one end an X-ray film and at the opposite end a source of X-radiation.  The movements of the bearing part,  the support arm and the film are mutually synchronized in such a way that an image of an area of the desired shape, for example the shape of the patient's dental arch, is obtained on the film during the movement.  The enlargement coefficient can be altered and the X-ray beam can be tilted to the desired angle in relation to the horizontal plane, whereby it will be possible to photograph more sharply than previously, for example, teeth oblique in relation to the vertical level.          The support arm is attached to the bearing part by structural parts which are equipped with guides extending longitudinally of the support arm so that the support arm can be transferred in a direction parallel to the X-ray beam.   Furthermore, the structural parts have curved rails, mutual movement of which affects the tilt of the support arm.   The adjustment movements are preferably effected by stepping motors.

Abstract: DISPOSABLE OR REUSABLE ANIMAL TRAP            ABSTRACT OF THE DISCLOSURE          A  reusable  or  disposable  rodent  trap,  having only two discrete parts, consisting of an unstable, tilt-able enclosure, upon whose exterior surface is mounted a rotating door member with elongated  side  panels,  which is prevented from rotating whenever the entrance side of the  enclosure  is  downwardly  inclined.   Contact  between the  elongated  door  side  panels,  and  the  surface  upon which the downwardly  inclined enclosure rests,  provides the  rotational  impediment.   A  rodent  traversing  the length of the enclosure to reach bait at the closed end causes  the  enclosure  to  incline upwardly, allowing  the door  to rotate closed by gravity.   The rodent's return to the entrance end causes the enclosure to again assume a  downward  inclination.   Since  the  door  cannot  be rotated  in either direction when the enclosure is down-wardly  inclined,  the  rodent  cannot open  the door when proximate to it.  The rodent, which will die of asphyx-iation  within  hours,  may  be  disposed of  by  simply inverting the trap.

Abstract: Abstract of the Disclosure The invention is concerned with a method for the manufacture of a laminated beam out of sheets of veneer as a continous process.  According to the method, the sheets of veneer are stacked, in consideration of the sequence of stacking, as glued or non-glued as a continuous setting consisting of a number of layers corresponding to the desired thickness of the beam on a suitable transfer base.   This setting is passed on the base into a preliminary press, pressed in the preliminary press, as well as passed into a hot press (2) for the purpose of hardening the glue.  In order to permit a more efficient operation of the hot press, in the method a continuous gap (3) free of adhesive and having a width equal to the width of the whole setting is produced in the setting between at least two desired layers of veneer, along which said gap the beam blank is divided (4), after the stage of preliminary pressing, into separate blank lines.  The blank lines are then passed into hot-press gaps of their own.

Abstract: TENSION ELIMINATOR FOR A VEHICLE      SAFETY BELT RETRACTOR            ABSTRACT      A  safety  belt  retractor  mechanism  for  vehicle passengers  is  described  which  has  an  apparatus  for selectively relieving belt retractive tension on the passenger.   The apparatus may be either manually or automatically engaged at a first extensive position of the belt corresponding to the buckled up position such that, for a single extractive movement of the belt by a first predetermined amount of "slack," the belt is locked against further retractive movement below that position, thereby relieving the retractive tension of the belt on the wearer.  Further extensive and retractive movements of the belt beyond the tensionless position and less than a second predetermined amount, such as would result from passenger forward movements to reach controls,  etc., result in normal retractive tension in the belt against the passenger until the passenger returns to the buckled up  position.    The  apparatus  then  "remembers"  this position and restores the slack to the wearer.  Upon extractive movements of the belt greater than the second predetermined  amount,  or  upon  manual  or  automatic disengagement  of  the  tensionless mode,  the  retractive tension of the belt below the slack position is restored until again reset by the passenger.     The apparatus is distinctive in its use of a Geneva mechanism to drive a memory disk having a pair of cams on its surface at a reduced rate through a frictional clutch to operate a locking pawl cooperating with a ratchet disk attached to the spool of the belt retractor to lock and unlock the spool at the appropriate positions.  A control arm indexes the memory disk relative to the locking positions and the Geneva mechanism permits significantly increased extensive movements of the passenger beyond the slack position without unlocking the rnechanism,  as well as increased accuracy of control over the belt slack and unlocking positions.
