Abstract: ABSTRACT OF THE DISCLOSURE      Apparatus for precisely machining the surface of a workpiece comprises a rotating plate with a flat, horizontal abrasive-laden surface against which the workpiece surface is forced by gravity. The workpiece is carried on the free end of an arm pivotably supported remote from the end of the arm carrying the workpiece.  Loading of the workpiece work surface can be varied by shifting weights along the length of the arm or transverse to the length of the arm.  The workpiece itself can comprise a bar on which several magnetic transducing heads have been deposited.  Machining the workpiece surface to a preferred position accurately defines a dimension of choice, such as the throat height of these transducers.

Abstract: ABSTRACT OF THE DISCLOSURE    The present invention relates to an apparatus and method for rapidly and accurately inserting axial lead components such as capacitors and resistors or the like into printed circuit boards mounted in an X-Y PC board positioning device. In accordance with the invention a plurality of magazines each of which contain a multiplicity of the components are loaded into a receiver chute of the apparatus. The apparatus functions, responsive to a signal from the PC positioning device, to remove an individual component from a magazine, deflect the leads to a position at right angles to the body of the component and insert the thus formed leads accurately into spaced apertures of the PC board which have been manuvered by the X-Y apparatus to a component receiver station.          The device includes means for automatically removing exhausted magazines and replacing the same with filled magazines.

Abstract: ABSTRACT OF THE DISCLOSURE Printed products and their respective corres-ponding printing plates are divided into a plurality of image elements.  For each image element the surface coverage is determined by photoelectric measurements; a reference reflectance value is then calculated from these measurements, taking into consideration such parameters as the printing characteristic.  These reference reflectance values are compared with the actual reflectance values measured on the printed products and the results of the comparison are evalu-ated to form a quality measure and to calculate control values for the ink feed devices of the printing machine.  In this manner, the use of special color measuring strips may be eliminated.

Abstract: ABSTRACT    A solid fuel gasifying unit is used to convert coal and other  combustible  organic  solids  to  gaseous  end products.  Solid feed enters the vertical preheat zone of S-shaped gasifying unit and is mixed with a hot recycle reagent such  as  clay.   The  solid  material  fills  the preheating zone of the unit to an elevation sufficient to create a  gravitational  particle  flow  which  forces  the solid particles in the lower end of the zone into the bottom  of  a  vertical  gasifying  zone  and  through  the remaining sections of the unit.   In the gasifying zone, a fluidizing  gaseous  stream  such as carbon dioxide or steam is  injected  to  enhance  the  flow  of  the  solid particles.     Also disclosed is a gas fractionating unit and a relatively high pressure solid fuel gasifying unit which contain a  reagent  powder  having  a  significant  weight difference in reduced form as compared with the weight of the powder in oxidized form and which may be circulated through the unit under  gravity  flow during  oxidation-reduction chemical  processing.   The gas  fractionating unit may be used in  combination  with either  gasifying unit, and  each  unit  provides  an  efficient  means  to circulate solid particles.

Title: Methode and system for upstream data packet time slot synchronization with downstream vbi in a two-way catv system

Abstract: ABSTRACT OF THE DISCLOSURE         Synchronization of upstream data packet time slots with the vertical blanking interval (VBI) of a video signal transmitted downstream from the headend is provided in a two-way cable television (CATV) system.  Coded data transmitted during a designated VBI line from the CATV headend is compared with system data stored in each subscriber terminal for generating a match signal.  The match signal is used to interrupt a microcomputer which then divides the next video signal raster scan field into 8 equal time slots during any one of which an upstream data packet may be transmitted.  Upstream data is thus accurately synchronized with a downstream vertical scan rate signal in reducing the likelihood of collisions between upstream data packets and increasing through-put in a two-way CATV system.

Abstract: MULTIPLE FREQUENCY DIGITAL PLL            Abstract An improved multiple frequency digital phase-locked loop circuit is described.  The improved digital phase-locked loops utilizes a single circuit to effect both phase and frequency adjustments.  The multiple frequency digital phase-locked loop effects phase adjustments by selectively combining or subtracting a reference clock signal with a derived programmable clock signal thereby generating a composite digital phase-locked loop clock signal.  The multiple frequency provides frequency adjustments by selectively adding or subtracting pulses from the composite clock signal at a rate determined by a programmably controllable clock signal.  The improved multifrequency digital phase-locked loop is suitable for use as a tone detector with the addition of a lock detector wherein the phase-locked loop can be programmed for a plurality of known operating frequencies.

The electrochemical apparatus will typically comprise two or three electrodes, including one working electrode onto which one or more of the components may advantageously be immobilised.       An artificial generation or enhancement of perturbation of electron transfer is preferably performed by displacement of the complex formed relative to the unbound labelled component.

Abstract: PROGRAMMABLE WORD LENGTH AND SELF-TESTING MEMORY     IN A GATE ARRAY WITH BIDIRECTIONAL SYMMETRY                 ABSTRACT OF THE DISCLOSURE The ease and versatility by which logic functions may be implemented in a semicustom CMOS gate array is substantially increased by disposing core cells (62, 67) within the gate array about a plane (18) of mirror symmetry.  Such a gate array is devised with mirror symmetry in two orthogonal directions.  A memory design of general utility and with particular utility in a gate array is devised so as to operate with a programmable word length.  The word length of the memory is programmed by choosing an appropriate integrated circuit metal mask option to be utilized in the memory circuit design at a data bus input and output mapping.  In the event that the memory is entirely included within a large scale integrated circuit, such as a gate array, a circuit design is further devised for providing a self-test of the operability of such a fully included memory without the necessity of providing input/output pins communicating with the memory (70) or other external test signals.  The self-test is activated by applying a single external start signal at a corresponding single external circuit pin (line 206) with an indication of failure at any point during a complete memory test cycle being coupled to a second external failure pin (208).  A self-test protocol is utilized wherein an internal counter (216) generates the addresses of each memory location and stores that address as data within the memory location and the inverse of the address as data.  In each case, what was then written into the memory is compared to that which is later read from the memory to thereby validate operability of the memory.
