Abstract: ABSTRACT OF THE DISCLOSURE       The present invention allows for the rapid conversion of food packaging machines to accommodate different sizes of containers in a fairly simple manner.  This is accomplishes through the use of a machine having a two-component conveyor, namely a base plate sized to receive the largest container and a replacable cover plate releasably secured to the base plate and having aperatures alignable with the aperatures of the base plate but sized to receive one particular size of container.  When a different size of container is to be packaged the cover plate is replaced with the appropriate size cover plate and various internal components of the apparatus adjusted through the large aperature of the base plate.  The base plate provides structural support for the cover plate and minimizes the possibility of damage through buckling or bending of the conveyor plates.  This two-piece conveyor system also allows the base plate to be made of light weight aluminum and only the cover plate need be made of stainless steel.

Abstract: ABSTRACT OF THE DISCLOSURE The automatic safety gangplank includes a plurality of cooperating ladder sections which are extendable from a fully telescoped or retracted position to an elongated position for extension from a dock to the deck of a ship.          The end of the base ladder section is connected to a rotatable turntable and is equipped with a pair of lift cylinders.  The turntable and the lift cylinders are connected to respectively rotate and elevate the base segment at all times, when the other gangplank ladder sections are either in their extended or retracted positions.  A gangway extends from the end of the outermost ladder section in angular relationship and is positioned upon the deck of the ship.  Automatic controls which are responsive to changes in elevation of the deck relative to the dock are provided to automatically either extend, retract, elevate or lower the safety gangplank as may be necessary to continuously maintain a safe walkway between the dock and the deck of the ship for all relative positions of the deck when the ship is either simply docked or when it is being loaded or unloaded.

If the hP + 1 which has been determined to be prime is not of the desired length, hP + 1 is placed in the sequence of prime numbers and a new h selected to be used to find the next prime number in the sequence in accordance with the above-described procedure by forming a new hP + 1 in which P is the previously determined prime number in the sequence of prime numbers.  When a prime number in the sequence of prime numbers is found which is of the desired length, it is input into the encryption/decryption key generator for generating the RSA public-key encryption and decryption keys.

Abstract: ABSTRACT:       Device for detecting radiation and semiconductor device for use in such a device.           In a radiation-sensitive semiconductor element which is divided into a number of sub-elements, the surface potential in the sub-elements varies in the case of inci-dent radiation as a result of charge carriers generated by the radiation. As soon as an adjustable threshold value of this potential is reached in one or more of the sub-elements, a current starts to flow which is signalled by means of a detector and a detection unit.         Because the speed of reaching the threshold value depends on the intensity of the radiation, the time measured between the adjustment of the threshold value and the signalling of the current is a measure of the radiation intensity.          By means of such a semiconductor element, the associated detection unit and extra electronics, if any, the energy or the cross-section of a beam can be determined and be readjusted; if necessary.          Such a semiconductor device can also be used very readily for focusing, for example in VLP apparatus.
