Abstract: REPEATER TRUNKING SYSTEM              ABSTRACT OF THE DISCLOSURE          Arrangement for establishing communication between a first mobile radio station and a second mobile radio station through a repeater over a radio frequency channel selected from a plurality of such channels. In an idle mode, a mobile station searches the channels for a predetermined group signal iden-tifying it as belonging to a particular group of mobile stations.  When that predetermined group signal is received on a channel, the mobile station is enabled on that channel so that it can communicate with a call originating mobile station belonging to the same group.  In a call originate mode, a mobile station searches for an idle or unused channel identified by the absence of a busy signal.  When an idle channel is found, the call originating station transmits a busy signal.  The repeater, hearing the busy signal, transmits an acquisition signal.  This acquisition signal is detected by the call originating mobile station which thereafter transmits a predetermined group signal for enabling other mobile stations in the common group on that same channel.

Abstract: REMOTE CHALKBOARD AUTOMATIC CURSOR            Abstract of the Disclosure A telautograph system allows a user at one location to write on a special surface, such as a chalkboard, and have the image appear at remote screens. Presently, a user wishing to call attention to an entry already written on the board must make a new line or must circle the item to which the remote viewers' attention is to be drawn.  This procedure unduly clutters the image and a system has been devised which provides for a cursor (a graphical hand) to appear on the remote screen when the user touches the input surface at a point. The cursor also appears when the user is writing on the surface so as to call attention to the newly formed images.  When pressure on the writing surface is released the cursor remains on the remote screen for a finite period and then automatically disappears, leaving the image unencumbered. When information is being removed from the input surface a graphical eraser appears at the remote screen at the site of the removed information.

Abstract: ABSTRACT OF THE DISCLOSURE:        The inflationary tendencies which have prevailed throughout the world for years, and the considerable increase of transactions effected with the aid of machines for vending merchandise and services, have resulted in a need for coins having a high value.  Public authorities who are responsible for the coinage have considered the use of smaller coins for this purpose.  These coins should differ in color from the existing coins having the highest value. Particularly gold colors are suitable for this purpose. For this reason there is a demand for a gold-colored material which can well be processed to make coins by casting, rolling and stamping and has a high resistance to tarnishing so that it retains as long as possible the original golden color. Thus in accordance with the invention coins or the like can be made from a copper-base allow which contains 4 to 6% nickel, 4 to 6% aluminum, balance copper and inevitable impurities which are due to the manufacture.
