Abstract: ABSTRACT:        The invention relates to an apparatus for and a method of determining the relative position and orien-tation of an object by way of mechanical procedure. The objects are transported in a first movement direction by a conveyor belt. A line array of photodiodes is ar-ranged transversely to the translucent conveyor belt.          The information of these diodes is scanned in synchro-nism with the movement of the belt. The extreme signals in the longitudinal and the transverse direction of the belt indicate the tangent points of two sets of mutually parallel, but transverse relative to each other, tangents to the objects. The relative positions of the points are compared with a stored system of coordinates for regularly spaced orientation directions of the objects.          The closest correspondence offers the orientation and position of the object. Thus, it is not necessary to memorize each time the positions of objects in an object handling apparatus or similar, so that the pro-cessing is simplified.

Abstract: ABSTRACT In synthetic resin-sealed optocouplers, undesired field effects occur when high voltages are connected between the transmitter and the receiver.  Such field effects can be eliminated by the provision of optically transmissive screening electrodes on the oxide frame of the collector-base diode and the base-emitter diode.  As screening electrode material it is advisable to use polysilicon in a layer thickness such that the reflection at this layer of the optical radiation employed is minimised.

Abstract: TRAP FOR SMALL ANIMALS DOING HARM TO POSSESSIONS          ABSTRACT OF THE DISCLOSURE          The specification discloses a trap for small animals or birds.  The trap includes a base plate having an elongated opening at one end and rotatably supporting a resilient or elastic plate at an opposite end.  The free end of the elastic plate can be inserted in the above mentioned elongated opening, and the elastic plate is longer than the base plate and is formed with an engagement projection adjacent the free end thereof.  In setting the elastic plate, it is bent into an upward curve and an engagement member is interposed between the upper surface of the base plate and the engagement pro-jection so as to engage the elastic plate and maintain its curved condition.  The engagement member will be moved by a small animal taking a bait or by the weight of a small animal treading on the base plate.  Such movement of the engagement member results in relieving the engagement, so that the elastic plate is instantaneously elastically restored to its flat condition, thereby trapping the small animal by squeezing it between the base plate and the elastic plate.  The trap has the advantage of being cheap and simple to manufacture and of not appearing particularly dangerous to cautious animals or birds.
