Abstract: Abstract A pattern for forming a sand mold for a one-piece annular casting having a radially inner ring, a radially outer ring, and a plurality of angled blades extending in a spaced, annular array between the rings.  The pattern includes a plurality of segments, each having a first end portion defining a portion of the profile of one of the rings, and a second end portion defining the profile of a blade.  An apparatus supports the segments in an annular array to define cumulatively a pattern structure corresponding to the configuration of the one ring and blades, and a removable ring coaxial therewith provides a pattern for the other one of the rings.  The segments can be supported in annular array about a mandrel and can be circumscribed by a split ring defining the pattern for the outer blade support portion of the casting.  The inner portions of the segments can be defined by angled side surfaces which, in alternate ones of the segments in the annular array, converge and diverge toward the center of the array.  Upon completion of the forming of the sand mold about the pattern, the mandrel and outer ring can be removed, permitting the segments having the inwardly diverging side faces to be withdrawn inwardly from the array and permit the remaining segments then to be withdrawn inwardly therefrom.

Abstract: ABSTRACT OF THE DISCLOSURE         A pyridine-free Karl-Fischer reagent for the determination of water is provided herein.  The reagent comprises a solvent solution containing sulfur dioxide and an amine in a Karl-Fischer reagent solvent, the amine being functionally equivalent to pyridine in a Karl-Fischer reagent, and a titrating agent containing iodine in a Karl-Fischer sol-vent.  The molar ratio of amine to sulfur dioxide is from 2:1 to 1:1 and the reagent is essentially free of pyridine.  Thus, a stable Karl-Fischer reagent has been provided which produces exact end points.  The reagent is less toxic, causes less environmental pollution and is less expensive than conventional agents.

Abstract: The present invention relates to a process of coupling optical fibers by means of a holographic lens, and an apparatus for carrying out this process. A holographic lens H2 is recorded conventionally by utilization of a provisional hologram H1, by means of two monomodal optical fibers mounted by their respective end pieces in a block used to support the holographic lens. The block has bores, clearly defined in shape and position, into which are introduced the end pieces of monomodal fibers to effect recording of the holographic lens, and in which are fixed the end pieces of multimodal fibers which are to be optically coupled after withdrawal of the monomodal fibers. The process and apparatus of the invention enables the speckling phenomenon, i.e., that of non-uniform distribution of light in the transmitted beams, to be suppressed, improving the efficiency of the holographic lens.

Abstract: Abstract A data communications transceiver for transmitting signals to and from the communicating medium, with the transceiver including an input terminal, a short time constant differentiator connected to the input terminal to differentiate signals applied thereto, a Schmitt trigger supplied with the output of the short time constant differentiator for producing a corresponding square wave output signal, a first driver supplied with the square wave output of the Schmitt trigger for supplying it to the communicating means, amplifying means for receiving signals from the communicating medium and for producing an amplified output therefrom, a second short time constant differentiator supplied with the output of the amplying means and for supply-ing it to a second Schmitt trigger for producing a corresponding second square wave signal, and a second driver supplied with a second square wave signal for supplying it to an output terminal.  In the preferred embodiment of the invention, electromagnetic inter-ference is suppressed by connecting a bifilar trans-former between the output of the first driver in the communicating medium, with the primary of the transformer being in series between the driver and the center conductor of the shielded communicating medium and with the secondary of the transformer being con-nected in series between the shield or the communi-cating medium and the floating ground of the trans-ceiver circuit.  A bypass capacitor is connected between the shield of the communicating medium and the circuit ground.  Furthermore, an enable circuit is connected between the amplifying means and the second Schmitt trigger to only enable the Schmitt trigger when the amplitude of the received signal exceeds a predetermined minimum which is higher than threshold level of the Schmitt trigger.

Each guide track is associated with one of the lower guide ledges and each guide track and respective lower guide ledge define a pair of working surfaces facing one another.  Magnets are mounted adjacent the working surfaces for generating a magnetic force acting perpendicularly to the wall panels in the direction of the side edge of the partition wall thereby to urge the lower guide ledges of the wall panels against the lower guide member in the aforesaid direction.

Abstract: ABSTRACT   The invention provides an electrode material and a method for its manufacture for use in electrochemical reactions.  The electrode material com-prises bulk titanium oxide having a general formula TiOx where x is in the range 1.55 to 1.95.  The electrode is titanium-free and hence may be used as a cathode as well as an anode.  The bulk titanium oxide may be used as an electrode material in its own right or may be used coated with a suitable anodically active material or cathodically active material.  Platinum group metals and platinum group metal oxides are particularly suitable coatings.  The TiOx material may be made by the hydrogen reduction of titanium dioxide and the material may be made by hydrogen reduction to a final shape or by hydrogen reduction of a powder and subsequent compaction of the reduced powder.  The invention is also concerned with electrochemical cells utilising such electrodes, particularly electrochemical cells involving the electrochemical treatment of a chloride-containing solution. The electrodes may be used as bipolar electrodes in such cells.  By utilising the electrode materials which do not include titanium the material is particularly resistant to hydride attack and to acid attack.

Abstract: BIASED TRANSMISSION CONTROL SHAFT        ABSTRACT OF THE DISCLOSURE           A manual shift transmission having multiple input and output portions is provided with a control having input and output shift rails. A laterally movable control shaft extends axially through cutouts in respective shift rails and carries cams adapted to cooperate with cam follower surfaces on corresponding cutouts to effect rectilinear movement of the shift rails upon rotation of the control shaft.  The cams are arranged on the shafts so that the shaft may be positioned to place respective cams in register with the input and output shift rails while all other cams are out of register with the rail cutouts.  The shift movement of respective output and input shift rails is overlapped during the rotation of the control shaft to decrease the throw of the shift lever.  The control shaft is spring biased to provide variable resistance in response to movement of a control lever to enable the operator to determine his position in the shift pattern of the transmission.
