Abstract: A B S T R A C T     A conditional replenishment video data transmission system involves the transmission of updating digital data for clusters of consecutive picture elements, all or most of which show a change since the previous frame, in lines of a raster over an image to be transmitted.        The lines of the raster are numbered cyclically in groups of 8, the numbers being part of line synchro-nising code words, and the position along a line of the first element of each cluster is identified by a number.  The data are transmitted at a constant rate from a transmitter buffer to a receiver buffer and an auxiliary data store records the addresses of the line synchronising code words in the receiver buffer.  The address of the receiver buffer read by a reading means can be corrected by reference to the address data in the auxiliary storage means if for example the line numbers do not follow in sequence or the element addresses are not in ascending order due to corruption during transmission.  Alternatively, the reading means may be controlled at all times by the address data in the auxiliary storage means and not only when a tracking error has occurred.  The tracking of the received data in the receiver buffer by the reading means may show a consistent error relative to the position predicted by the assumed transmission delay time, preferably such tracking errors are corrected by a whole frame jump using a receiver buffer of more than one frame capacity.

Abstract: Method and Apparatus for Controlling Diesel Engine Exhaust Gas Recirculation Partly as a Function of Exhaust Particulate Level Abstract A method and apparatus for controlling the re-circulation of exhaust gas in a diesel engine in-cludes an EGR valve responsive to an EGR control signal for relatively opening and closing a recir-culation duct to the passage of exhaust gas there-through.  A sensor provides a signal indicative of the level of particulates in the exhaust gas stream. Control circuitry responsive to various signals in-dicative of engine operating conditions, including the signal indicative of exhaust gas particulate level, provides an EGR control signal for regulating the EGR valve at least partly as a function of the sensed level of particulates in the exhaust gas stream.  The engine operating condition signals ty-pically are indicative of the speed of the engine or fuel injection pump, the engine load, and engine operating temperature. The particulate level signal is preferably provided by electrostatically sensing the passage of packets of charged particles by an electrically-passive, annular electrode positioned in or adjacent to the exhaust gas stream.     The control circuitry includes storage of open loop EGR valve control signals as a function of speed and load, as well as particulate objective signals also as a function of speed and load.  The sensed exhaust gas particulate level is compared with the appropriate particulate objective signal for the development of an error signal, which error signal is then used in an adaptive manner to adjust the open loop EGR control signal in a direction to diminish the particulate error signal.  Such adap-tive control of the EGR control signal as a function of the exhaust gas particulate level is further ad-vantageous because a predeterminable relationship exists between exhaust particulate levels and NOx levels as a function of percent EGR.  EGR control may be inhibited by depressed engine temperature.

Abstract: - -   ABSTRACT OF THE INVENTION     In post and runner type scaffolding, a uniquely formed integral connector is created from the end of the runner or other similar cross-member.  The integral connector secures to a scaffolding post bracket (preferably in the form of a ring flange concentrically affixed to said post and having a circular array of identical cutouts) and abuts forcefully against the convex surface of said post by means of a wedge acting through one of said cutouts.  The connector has a longitudinally extending cross-slot in its end of a width and depth to accommodate the bracket therein, dividing the end into upper and lower limbs.  The free end of each limb terminates with the tubular walls thereof reformed from the tubular shape of said cross-member preferably to a more flattened shape effective to strengthen and stiffen said limbs for their intended use of supporting scaffolding loads and connection stresses.  A hole is formed in each limb so as to align generally with any one of the cutouts in said bracket to accommodate said wedge. - -;

Abstract: DISPOSABLE GARMENT WITH BREATHABLE LEG CUFFS        KENNETH B. BUELL                            ABSTRACT     Disposable diapers provided with breathable leg cuffs. Disposable diapers comprise a topsheet, an absorbent element, and a backsheet. The leg cuff of a disposable diaper is that part of the diaper which fits about the wearer's leg. Extensions of the backsheet can be used to form cuffs which are frequently elasticized. In the present invention the cuffs are formed of a material which allows passage of vapor ("breathes") while tending to retard the passage of liquid. Apertured thermoplastic films are examples of such materials. Certain advantages accrue in cuffs which are permeable to vapor in their distal portions and impermeable in the portions adjacent the absorbent element. If the disposable diaper has a breathable backsheet, the cuffs are constructed to be more permeable to vapor per unit area in their breathable portions than is the backsheet.

Abstract: Abstract A multi-metal container separating apparatus is pro-vided for orienting, delidding and compacting containers.  The apparatus includes an orienting unit which orients the lids of the containers in a predetermined direction.          After orientation, the containers are fed to a delidding unit.  The delidding unit includes a clamping assembly for gripping each container during the delidding process in which one end is removed from each container.  While each container is held fixed in position, a piercing element is extended from within a moving plunger body to penetrate an end of the container.  The piercing element is then retracted within the plunger body.       Movement of the plunger body continues through the body of the container and the plunger body engages the other end of the container.  The force of the plunger body in a direction inwardly to outwardly of the con-tainer removes this end of the container.  The delidded container falls to a pivotable support platform.  A compacting plate is fastened to the support platform and forms part of a compacting unit wherein the delidded container is flattened between the compacting plate and a wall of the compacting unit.

Abstract: LIGHTWEIGHT METAL-HYDROGEN CELL WITH IMPROVED PLATE STACK SUPPORTING MEANS     Abstract of the Disclosure A metal-hydrogen cell is disclosed in which the durability of the battery is substantially increased and the system mass and volume are reduced.  A plate stack within the casing is compressed by a spring which is supported from the casing without support from the terminals.  The spring support is external to the cell stack; that is, it does not pass through the stack.  Optionally, terminals are positioned at non-axial positions on the casing, extending outwardly from each domed end of the casing at axially offset positions on the domed ends so that the terminals do not extend beyond the length and diameter of the casing.  This contributes to the reduction in the effective size of the cell.

Abstract: ABSTRACT                Electrical Insulator The invention provides an electrical insulator comprising a cylindrical core  of an insulating refractory material, such as porcelain, on to a portion of the curved surface of which a sleeve      of insulating polymeric materal is fitted.  Metal end-caps    , for electrically connecting the insulator, are fitted to the ends of the porcelain core such that there is an exposed portion      of the curved surface of the core between the sleeve and each end-cap.  Thus, any damaging electrical activity which takes place at the metal end-caps is directed primarily on to the surface of the porcelain core    , and not on to the surface of the electrically vulnerable polymeric sleeve    , which serves to protect mechanically the relatively brittle porcelain core.            Optionally, the polymeric sleeve     may have a convoluted or a shedded outer surface      to increase the leakage path length of the insulator, or to prevent the formation of a continuous moisture path, or both.
