Abstract: ABSTRACT OF DISCLOSURE          An electrode system for voltametric measurements for measuring oxidative and reductive compounds in aqueous solutions primarily in the paper and pulp industries, said system comprising a working electrode (l), a counter-electrode (2) and a reference electrode (3), these being connected to a voltametric measuring apparatus (4). The aim is to introduce an electrode system mountable in the process pipeline with greater ease than electrodes of prior art and of a construction simpler than earlier systems, and more durable and less maintenance-requiring than these.         As taught by the invention, the reference electrode (3) is a metal electrode and has been made for instance of silver, platinum, gold, titanium or "Hastalloy C" steel. The electrodes are advantageously installed together and in one and the same pick-up and disposed to be so placed in the process pipe system that the solution flowing in the pipe system flushes the electrodes.

Abstract: ABSTRACT         A removable reusable nut lock system (10) of the locking cap type for positively selectively removably retaining a standard nut (12) on the externally threaded end of a shaft (14) is provided.          The lock nut assembly comprises an internally threaded bore (22) provided in the end of an externally threaded shaft having internal threads (24) of an opposite hand as the external threads (16) on the shaft.  A locking cup member (26) is provided or slipping over the outer periphery of the nut for rotation therewith and the locking cup member is provided with a flange (32) having a plurality of ramp type ratchet teeth (38) on the outer periphery thereof.  A locking cap member (28) is provided having an externally threaded stud (50) fixed thereto and a plurality of locking fingers (58, 60) extending radially outwardly and downwardly therefrom.          The resilient locking fingers are designed to ratchet over the ratchet teeth of the locking cup upon tightening of the locking cap and will resist rotation of the nut member and locking cup in the removal direction of rotation of the nut relative to the externally threaded shaft.

Abstract: ABSTRACT OF THE DISCLOSURE          A disc brake of pin-sliding caliper type having a boot protector, including an extension of a liner disposed between a side end surface of a brake pad and an opposite torque receiving surface of a torque member movably supporting the brake pad toward and away from a friction surface axially of a disc rotor.  The protector prevents excessive heat reaching a boot covering an exposed portion of a slide pin which guides a caliper to urge the brake pad against the disc rotor.  The protective extension of the liner extends parallel to the axis of rotation of the rotor away from one end of the torque receiving surface axially remote from the rotor, and is interposed between the boot and a heat source such as the brake pad and the rotor.  The liner is preferably provided with a resilient section biasing the brake pad in a direction parallel to the surface of the disc rotor to thereby serve as an anti-rattle spring.  The boot protector may further include another extension of the liner extending substantially radially outwardly of the rotor away from another end of the torque receiving surface proximate to the periphery of the rotor radially thereof.

Filed: 1984-03-15
Granted: 1989-02-28
Abstract: Disclosed is a sliding gate valve employed on the side of a furnace as a furnace valve, in which the mechanism is so structured that the shut off occurs by directing the slide gate to the up position rather than the down position. In addition, to facilitate a reduction in space at the slide gate, the slide gate is desirably configured to be asymmetrical, with the short end extending upwardly from the pour opening in the nozzle. A refractory lined heat shield protects the sliding gate carrier and also serves to mount a collector extension when used. More specifically, the slide gate is provided with a metallic frame which retains a monolithic refractory into which erosion resistant refractory inserts or preformed members are cast. Means are desirably provided to remove the spent refractory for remanufacture thereby reclaiming the casting. Similarly in the top plate, means are provided for remanufacture and for facilitating proper orientation of erosion-resistant refractory inserts such as zirconium oxide in the manufacture of the stationary plate. The top plate is symmetrical to provide full travel pressure face relationship with the sliding gate. Both the stationary plate and slide gate casting having spring pad back up reinforcements. The top plate desirably has means for securing a well nozzle to it.

Abstract: ELECTROLYTIC RECOVERY SYSTEM         FOR OBTAINING TITANIUM METAL               FROM ITS ORE            ABSTRACT OF THE DISCLOSURE     A process and system, including a single electro-lytic/reaction cell, for extraction of titanium sponge from rutile ore.  Magnesium chloride is electrolytically separated into magnesium metal and chlorine gas within the cell.  The chlorine gas produced is reacted with rutile ore and coke to produce titanium tetrachloride in a separate chlorinator and the product is directed to the cell subsequent to completion of electrolysis.  Titanium tetrachloride is reacted with magnesium metal in the same cell where the magnesium is produced to form titanium sponge and magnesium chloride.  The titanium sponge is separated within said cell with the magnesium chloride being recovered and recycled.          Major impurities are separated by distillation.  Plural electrolytic cells can be coupled to a single chlorinator in a continuous process.  Very pure titanium sponge is produced with this self-replenishing process.

Abstract: RCA 79,617 ABSTRACT OF THE DISCLOSURE         A power supply and deflection circuit for a video monitor provides multiple horizontal scan rates.          A switch is used to select the desired scan rate.          Operation of the switch determines the proper operating voltage level for the horizontal deflection circuit.  A zener diode provides a high or low signal in response to the level of the determined operating voltage.  The horizontal oscillator frequency and the value of the S-shaping capacitor are determined in response to the high or low signal.  The operation of the switch, therefore, provides the necessary circuit parameter changes for each of the horizontal scan rates selected.

Abstract: ABSTRACT            A flat, rectangular box made of cardboard contains a bag of multi-layered foil material.  A tube, which is disposed in the inside of the box when the package is in the transport condition and can be removed from this through an opening which is closed by a tear-off strip, is connected in a fluid-tight manner with the bag by a connecting piece.          An outlet provided at the free end of the tube is controlled by a pressure relief valve provided in the tube and which opens in the direction of the outlet.  The walls of the narrow sides of the box each have a longitudinal fold along which these walls can fold outward when the broad sides of the box are pressed together in order to empty the bag which is filled with a fluid, e.g. coffee extract.  The one-way package is particularly suitable for use in a beverage vending machine in place of the storage containers employed until now.  A suspension flap of the box, which can be separated away from one of the broad sides, is used for interchangeably securing the container in the automatic machine for the extraction of the fluid.
