Abstract: PHT. 82.347                  14 ABSTRACT:      A cellular radio system in which the mobile radio stations in the zone of any base radio station assign themselves to the control channels allocated to that base station so as to evenly spread the volume of traffic over such control channels.  The base station transmits on each control channel a channel group code signifying the range of group code numbers allocated to that particular control channel.  Each mobile station stores its identify-ing group code number, scans the group code numbers of all control channels, and assigns itself to the control channel having a channel group code which includes its group code number.  The spread of traffic over the various control channels can be changed by the base radio station simply by changing the channel group codes of the various control channels, without addressing specific commands to the mobile radio station.

Abstract: ABSTRACT         Apparatus is provided for addressing a memory by word and by one of a number of nibbles within a word, with the ability to increment or decrement nibble and word addresses and thereby access adjacent nibbles and words without having to generate new nibble and word addresses.  An initial word address is placed in an address counter and an initial nibble address is placed in a nibble control.  The two addresses indicate a particular nibble within a particular word.  Thereafter, only increment or decrement signals are provided to increment and decrement the nibble address and/or the word address.  A nibble counter counts the increment and decrement nibble signals and when the last or first nibble in a word is addressed, an increment or decrement word address signal is respectively generated that changes the word address stored in the address counter.

Abstract: Abstract This invention relates to a tape reading system wherein the tape in a tape cassette has color marks on the tape to be read by an optical system, part of which is in the cassette and another part of which is in the tape drive. The part in the cassette consists of an optical element having mutually isolated light transmission paths.  The paths carry light reflected from or transmitted through different portions of the width of the magnetic tape.  The light is directed to optical sensors which are part of the tape drive.  A lamp, also part of the drive, illuminates the tape so that light shining on the tape will con-trast with the color marks.  Changes in contrast due to the color marks, trans-mitted through the optical element, are detected by optical sensors and converted to electrically readable signals.  A feedback circuit connected to the lamp and to the sensors provides electrical feedback to the lamp. The level of illumination detected by the optical sensors is kept constant relative to slow background contrast changes, although a low pass filter prevents the feedback circuit from responding to light signals representing the color marks.

Abstract: QUICK-CONNECT MECHANISM                   ABSTRACT OF THE DISCLOSURE            A quick-connect and quick-disconnect mechanism includes a male member which may be received in a female socket member.  Cam means is journaled in an eccentric cam follower surface in the socket and is capable of rotation about a second axis displaced from the axis of the socket.  A locking surface on the cam means faces in a longitudinal direction opposite the entrance of the socket and opposite that of a lockable abutment surface on the male member.  An aperture in the cam means is sufficiently large to accommodate the entrance of the lockable abutment surface on the male member.  The cam means is rotatable within the cam follower surface to move the cam locking surface with a radially inward com-ponent and a component of movement in a longitudinal direction away from the entrance of the socket to engage the lockable abutment surface to lock the male member in the socket.  The cam means may also have an expelling surface to aid in expelling the male member from the socket.  The foregoing abstract is merely a resume of one general application, is not a complete discussion of all principles of operation or applications, and is not to be construed as a limitation on the scope of the claimed subject matter.

Abstract: ABSTRACT OF THE DISCLOSURE           An  ALU  in  a CRT  display unit performs calculation based on line segment data provided from a line segment data providing circuit and data representing a border line provided from an area data providing circuit to obtain a ratio of a distance between the start point coordinates and the end point coordinates of the line segment to a distance between the start point coordinates or  end point  coordinates and a border  line of  a predetermined area.   When it is determined that the calculated ratio is larger than a predetermined value, the ALU sets new coordinates in the vicinity of a point of intersection between the line segment and the border line of the predetermined area instead of the start point coordinates or the end point coordinates of the line segment.  Then, based on the newly set coordinates and the data representing the border line, the ALU calculates by a middle point division method, a point of intersection between a  line  segment  connecting the newly set coordinates and start point coordinates or end point coordinates and the boarder line.  Thus, the time required for a middle point obtained by division to approach the border line can be shortened.

Abstract: ABSTRACT OF THE INVENTION    A hand-held tape measure is provided which includes a conveniently sized housing with an elongated measuring tape suitably coiled on a rotatable shaft mounted within said housing.  A sprocket arranged to engage the surface of the tape without slippage is mounted within the housing and drivingly connected to an encoding disk whereby the rotation of the disk is directly proportional to the linear movement of the free end of the tape.  The disk is divided into an equal number of alternating transparent and opaque segments and two energy sensitive coupler switches are mounted in conjunction with the disk to provide electrical outputs indicative of the adjacent disk segment to indicate the rotation of the disk.  The switches are offset circumferentially to provide a phase differential which indicates whether the tape is extending or retracting with respect to the housing.  The output from the switches is fed to an electronic circuit which counts and divides the output pulses with the result digitally displayed. A variable speed reversible motor which is powered by an internal power source can be drivingly connected to the tape to control its movement.  A switch is provided on the housing for controlling the direction of the motor. This switch can also include a lock for holding the tape in the retracted position when the motor is deenergized.
