Abstract: SEMICONDUCTOR MEMORY FOR USE IN CONJUNCTION WITH ERROR DETECTION AND CORRECTION CIRCUIT            ABSTRACT     A semiconductor dynamic memory circuit (10) includes a memory cell array (38) which includes a plurality of memory cells which are accessed through row and column lines by operation of row and column clock chain signals. A strap (68) is provided to operate the circuit (10) as either a memory which is refreshed according to internally generated addresses or a memory which is refreshed in response to externally supplied memory addresses and is easily incorporated into a memory system which utilizes error detection and correction during the refresh operation.  In the absence of the strap (68) a refresh signal (20)) refreshes cells of the array (38) in response to the address generated by an internal address counter (82).  The circuit (10) accesses a given memory location when an externally supplied address is provided together with a RAS signal (12) and a CAS signal (16).  When the strap (68) is incorporated into the circuit (10) the refresh signal (20) applied thereto causes the memory cell array (38 to be refreshed at the externally supplied address. The data within the memory cell array (38) is accessed in response to an externally supplied memory address, the RAS signal (12) and the CAS signal (16).  The CAS signal (16) is inhibited in the absence of the RAS signal (12).  The circuit (10) is used within a memory array (102) for reading out stored data together with error correcting bits while at the same time refreshing all of the memory circuits in the memory (102).  An error detecting and correcting circuit (160) is provided to evaluate the data read out from the memory circuits and to provide a corrected data pattern when erroneous bits are detected.

Abstract: ABSTRACT          IMPROVEMENTS IN OR RELATING TO DIGITAL TRANSMISSION                     SYSTEMS    A supervisory channel is provided on a digital transmission system by frequency modulation of the data signal transmitted along a transmission link which includes repeaters. The frequency modulation can be carried out using an elastic store.  Each repeater includes means for demodulating the frequency modulation so that each repeater can be addressed and interrogated.  Each repeater can also phase modulate the data signals on the return link to a terminal station so that signals indicative of an interrogated condition can be transmitted to the terminal station.

Abstract: PROCESS FOR THE PRODUCTION OF PAPER                 Abstract of the Disclosure This invention relates to the production of paper wherein a drainage and retention aid is added to an aqueous suspension of cellulosic fibers for making paper sheets.  The drainage and retention aid has a structure AB wherein the B portion of the structure is cross-linked by the A portion of the structure.  The A portion is a residue resulting from the removal of chlorine atoms from a cross-linking compound prepared by reacting a polyoxyalkylene glycol compound with a halogenated oxide in the presence of a suitable catalyst.  The B portion is the residue resulting from the removing of amino hydrogens from a polyamine compound prepared by reacting an initiator selected from the group consisting of alkylene glycols, polyalkylene glycols and water; a halogenated epoxide; and an amine.

Abstract: SELF-CLEANING FILTER ASSEMBLY FOR                   SOLENOID-ACTUATED VALVES                           ABSTRACT            Disclosed is an improved self-cleaning filter assembly for use in a solenoid-actuated valve of the type having a fluid pressure-operated diaphragm to control opening and closing of the valve.  Control fluid under pressure is admitted from an inlet chamber of the valve into a control chamber at one side of the diaphragm to maintain the valve in a closed position, and this fluid pressure in the control chamber is relieved by actuation of a solenoid to open the valve.  The self-cleaning filter assembly comprises a rela-tively rigid filter element for filtering the control fluid and a plurality of scraper blades mounted for scraping dirt, grit, or other deleterious matter from the filter element each time the valve is opened or closed.

Abstract: 14.                         ABSTRACT          "IMPROVEMENTS IN AND RELATING TO CYCLONE SEPARATORS"   The invention concerns a method of an apparatus for separating fluids containing particulate matter into two or more fractions of different densities, A cyclone separator (1) is utilised for this purpose and differs from previous constructions inasmuch as it is a uni-directional, air cored device having an inlet (i) only for the fluid (A) in the top and two, three or more separate outlets (11,15,37,41,45,51) in the bottom, remote from the inlet, one (11,41) of which outlets extends axially of the separator.  In operation particles (as defined in the specification) once separated from the streamline (A') in which they enter the device are constrained against traversing that streamline.  Means (5) are provided adjacent the inlet (7) to stabilise the initial flow of fluid.  The axially extending cutlet (11,41) may be adjustable and means (55) may be provided for elutriating heavy reject flow (Z).  Specific embodiments separate into light reject (X) and accept (Y) fractions; into light reject (X), accept (Y) and heavy reject (Z) fractions; and accept (X) and heavy reject (Z) fractions.

Abstract: ABSTRACT     A gate for use in a throttling valve is disclosed as used on a tundish.  The gate comprises a generally rectangu-lar refractory body having a longitudinal axis and a lateral axis transverse thereto a through-opening through the body defining a metal  flow orifice and the metal flow orifice being disposed on the lateral axis of the gate in offset re-lation to the longitudinal axis, with the extent of the off-set being in excess of the radius of the teeming orifice.          The sliding gate when used in a valve is shiftable into pos-ition and then may be translated laterally for throttling and full shutoff.   In the full shutoff configuration this allows a tube holder of the tundish disk to be moved in and out of position quickly.  The gate, when used in a tundish, provides increased control and facilitates fast replacement of various components.

Abstract: TRAP SETTING DEVICE          ABSTRACT OF THE DISCLOSURE         Double spring traps such the conibear trap are difficult to set due to the heavy duty hairpin type springs on either side thereof.  The present device consists of a crank, a length of cord or cable extending from the distal end portion of the crank and a spring ring anchor bar on the distal end of the cord or cable.  The bar is fed down-wardly through the upper loop and then through the lower loop and is positioned so that it cannot disengage from the lower loop.  The crank is fulcrumed across the top loop and rotated thus winding the cord or cable about the distal end portion of the crank which shortens the cord or cable and gradually and safely pulls the two loops together so that the detachable locking clip normally provided, can be engaged over the arms to hold them in this position.  The other spring is treated in a similar manner thus rendering the trap inoperative for baiting and setting purposes where-upon the clips can be removed.
