Abstract: ABSTRACT             A method of producing a leakage graded coaxial cable having a braided shield, in which ends of the shield wire are dropped as braiding progresses.  Gaps in the shield having progressively increasing size are produced through which the radio frequency field leakage occurs, which facilitates providing a constant radio frequency field around the cable.  The cable is coated with a jell flooding agent prior to extrusion of its protecton jacket, which fills the interstices and gaps of the shield, and solidifies to a waxy, semi-resilient consistency.  The resulting cable can be coiled and flexed, maintaining its shield reliability, and rejects water and fluids in case pinholes in the jacket occur.

Abstract: ABSTRACT OF THE DISCLOSURE An arrangement for generating in each switching panel of a multipanel switching facility of an electrical power distribution network a digital operating-state image derived from command inputs and switching position signals.  The digital operating state image is transmitted to a collecting memory arranged in a coupling panel which produces an overall image of all switching panels; which overall image is transmitted to the individual switching panels at periodic time intervals.  A checking procedure is then conducted in the individual switching panels using the overall image. This arrangement utilizes microprocessors which are coupled to one another so as to exchange data via several transmission paths which are one-bit wide. This arrangement obviates the need for an interlock cable harness in the switching panels and cross-cabling between the switching panels.

Abstract: ABSTRACT OF THE DISCLOSURE     A plurality of movable storage units each have a reversible motor for driving them in the proper direction in response to a user command to open an aisle between selected units.  There is a microprocessor-based programmable control module on each unit and there is a structurally similar module that acts as a system controller.  Four control lines interconnect the modules. One line is for sending digital command data away from the system controller and another is for sending sensing data toward the system controller.  Another line is for resync pulses transmitted from the system controller to the microprocessors simultaneously.  The processor in each module responds to a resync pulse by initiating definition of a specific number of time slots for containing individual high or low bits to enable serial transmission of encoded data representative of commands and sensed conditions.  The modules on each unit interpret or sense such conditions as to whether their start pushbutton has been pressed, whether their limit switches are closed to indicate proximity with another unit and whether a safety switch is open or closed.  This and other sensed information is sent serially to the system controller in serial form for being interpreted and the system controller sends back commands for enabling the unit modules to interpret the direction and limits of unit movement.

Abstract: ABSTRACT             An automatic gain control (AGC) circuit for a burst signal communication system has an AGC amplifier for receiving a burst input and pro-viding a burst output whose level is controlled in response to a control signal.  A negative feedback circuit including an envelope detector receives the burst output and provides the control signal.  The envelope detector envelope-detects the burst output and provides a first signal.  A converter converts the first signal into a binary signal by comparing it with a reference voltage.  A pulse generator provides a pulse signal of a predetermined pulse width in response to the binary signal.  An AGC amplifier driving circuit digitally processes the pulse signal, thereby providing the control signal. The output power of the AGC circuit of the invention does not vary regardless of variation in the burst time.

Abstract: ABSTRACT: Device for optically scanning a document. The device comprises N linear opto-electronic transducers (157, 159, 161) which are substantially aligned with spaces (183, 185) between adjacent transducers. With each transducer (157, 159, 161) is associated an individual imaging system (163, 165, 167) for imaging a narrow strip (171, 173, 175) of the document on the transducer. Each transducer (157, 159, 161) is displaceable with the aid of adjustment means with respect to the associated imaging system (163, 165, 167), as a result of which the whole can be adjusted so that the narrow strips ( 171, 173, 175) adjoin each other and are aligned so that together they cover a narrow elongate part (169) of the document. In this manner, a comparatively large document can be scanned with a high resolving power by means of comparatively simple and hence inexpensive transducers and imaging systems.

Abstract: ABSTRACT OF THE DISCLOSURE           The robot is composed of a figure simulating a boxer which is mounted to a post. A first arm is mounted to the post for pivoting in a vertical plane. A second arm is mounted to a vertical rod mounted within the figure. A prime mover causes the rod to rotate and as it does so, the second arm rotates in a horizontal plane. A roller is connected to the rod and periodically contacts the second arm thereby causing the arm to elevate. Gravity causes the second arm to fall when it is not contacted by the roller.          The roller is so positioned to the rod that it causes the second arm to elevate when the first arm is behind the figure and allows the second arm to fall when the first arm is in front of the figure.
