Abstract: ABSTRACT                     PASSIVE REPLICATOR   A passive replicator device has three propagation paths for propagating information therealong, the second and third paths being disposed adjacent to the first path in order to receive information from the first path so that information is propagated in all three paths substantially in a first direction.   The second and third paths have ends that are substantially adjacent to each other and in substantially parallel arrangement.   The first path has an end adjacent to the ends of said second and third paths and substantially in abutment therewith.   A plurality of elongated bars in substantially parallel arrangement are disposed to the mentioned ends of said first, and second and third paths.   An end of at least one of the elongated bars is interposed between the end of the first path and the end of at least one of the second and third paths whereby the elongated bars receive information propagating along the first path and expand this information to substantially encompass the ends of the second and third paths.   Each of the elongated bars has a length substantially greater than the length of the ends of the first, second and third paths.   A cutter bar is associated with the elongated bars, this cutter bar including an elongated bar having a relatively shorter bar portion disposed at an angle to the elongated bar and projecting between the ends of the second and third paths.  At least one repeller bar is arranged substantially normal to the direction of propogation adjacent the ends of the plurality of bars and the third propagation path.

Title: Transistor amplifier stage with selectively adjustabale gain control circuit
Inventor: BLACKBURN TOM L
IPC: H03G1/00
Filed: 1976-11-25
Granted: 1981-08-25
Abstract: ABSTRACT OF DISCLOSURE         Gain control circuits associated with the base and emitter electrodes of a common-emitter transistor amplifier st?ge include pluralities of electrically conduc??    crew-type switches and resistors.          The net gains provided by the associated gain control circuits are cumulative and determine the net gain of the stage.  The gain changes provided by individual switches of the base and emitter gain control circuits are also cumulative, the switches being selectively closed in a prescribed manner to provide step changes in the decibel value of the net gain of the stage in discrete steps of the same magnitude.  A plurality of transistor amplifiers with associated emitter gain control circuits may be connected in series, with the decibel values of voltage gains thereof also being additive, to provide additional steps and range of voltage gain.  Series resistors in the base gain control circuit are selectively short-circuited by screw switches to decrease the input resistance of the amplifier stage.  A bridging resistor is selectively connected across certain of the series resistors by one of these screw switches for causing the associated step change in the input impedance of the stage to be more nearly equal to the desired value.  Resistors in the emitter gain control circuit are electrically connected in parallel with the emitter resistor in the AC circuit equivalent of the amplifier in various configurations by screw switches to decrease the effective emitter resistance and thereby increase the decibel value of amplifier gain in steps of prescribed magnitude.  The emitter gain control circui? may be AC coupled to the emitter resistor and the emitter electrode of the amplifier.  Alt?rnatively, one side of this gain circuit may be directly electrically connected to the emitter electrode.  A resistive voltage divider network is then connected to the other end of this gain control circuit and across the positive and negative terminals of a source of bias voltage.  The network resistors are selected to provide the same DC bias voltage on both sides of the emitter gain control circuit.  This prevents DC current from flowing through the emitter gain control circuit as the resistance thereof is changed and thereby maintains the DC bias level on the transistor constant.  In this manner, the effective emitter resistance, and thus the amplifier gain, may be changed to any desired value without changing the operating point of the amplifier.

Abstract: A B S T R A C T         The removal of lignin from cellulosic pulp is achieved, with reduced cellulose degradation, by partially replacing chlorine with bromine in the acidic chlorination of the pulp.  The lignin is removed without appreciable discoloring of the pulp.  The present process is adaptable for incorporation into known multi-step processes for treating pulp, such as the halogenation, extraction and oxidation sequence.         The bromine-chlorine mixture used comprises between 10 and 70 weight percent bromine, and is used in a concentration of 4 to 14 weight percent, most preferably 6 to 8 weight percent, based on the dry weight of the cellulosic pulp.

Abstract: METALLOID FILAMENT WIRE MATRIX PRINT HEAD                       ABSTRACT    A wire matrix print head mechanism  s disclosed in which a wear and impact resistant, flexible, smooth, tough and economical metalloid element filament material is utilized as the impact print wire.  The wire material's flexibility eliminates many of the problems of breakage and brittleness failures encountered in previous designs.  The lower coefficient of friction and greater smoothness of the wire material lowers the magnet forces required to push the wires through wire guides in the print head.  The extreme hardness of the metalloid material combined with its high flexibility and toughness facilitate the production of impact and wear resistant, easily assembled long life wire matrix print heads.

Abstract: ABSTRACT OF THE DISCLOSURE In a field access type bubble memory system using a major loop-minor loop organization, additional redundant minor loops are included in each memory chip so that defective minor loops may be discarded and the mem-ory retain its nominal capacity.  Thus, the total number of minor loops is in excess of the nominal capacity.  A stationary register is placed adjacent to and parallel to a major loop and has as many register positions as the total number of minor loops on the chip.  An appropriate binary code identi-fies in the appropriate register location the corresponding minor loop which is defective, including nominally defective minor loops, if necessary, so that a number of minor loops equal to the nominal capacity of the memory are identified as good.  Each time the memory is accessed, the contents of the register are accessed, nondestructively, and read into and merged with the contents of the major loop on an every other one basis.  Appropriate logic identifies on an every other one basis which minor loop is to receive data and from which data can be read.
