Abstract: Pharmaceutical compositions of nalbuphine and 4,5-bis(4-methoxyphenyl)-2-(trifluoromethylsulfonyl)-1H-imidazole have been found to exhibit unexpectedly enhanced analgesic activity by applying an analysis model which considers data characterizing the analgesic effect of both the pure components as well as the fixed dose ratio combinations. This synergism enables the use of lower doses of either or both drugs with a concomitant reduction in risk of possible side effects.

Abstract: A layer-thickness meter for measuring the thickness of a non-magnetic layer upon a ferromagnetic substrate wherein the force required to raise from the layer to be measured a permanent magnet carried in a balanced lever arm is measured by means of a spring and taken as a measure of the layer thickness, the spring being stressed by rotation of a scale disc graduated in terms of layer thickness and co-operating with an index mark upon a housing of the meter, the circumferential edge of said disc being serrated or indented for engagement by a pawl so as to lock the disc in response to detachment of the permanent magnet from the layer surface, said pawl comprising a pivotally mounted bearing plate from which project two rigid stops which between them loosely embrace said lever arm at a location along said arm such that the pawl is actuated through one said stop to disengage from the disc edge when said permanent magnet is in contact with said layer surface and actuated through the other said stop to engage and lo

Abstract: A method is provided for treating glaucoma by systemic administration of nadolol or esters of nadolol.

Abstract: A process and apparatus for continuously forming a reinforced membrane of fluorinated polymers containing sulfonyl and/or carboxyl groups in melt-fabricable form and, after hydrolysis, the corresponding membrane in ion exchange form. The membrane thus formed has exceptional uniformity, and this membrane so made, when used as the membrane which separates the compartments of a chloroalkali cell, offers the advantages of low operating voltage, low power consumption and high current efficiency, and a long useful life without rupture.

Abstract: Novel particle reagent for light scattering immunoassays are provided. The particle reagents are high refractive index shell-core polymers covalently bonded to compounds of biological interest. A method of measuring unknown concentrations of these compounds of biological interest by measuring changes in turbidity caused by particle agglutination or its inhibition is also provided.

Abstract: Activated carbon fabric is made directly from aramid fabric in a single carbonization/activation step.

Abstract: A polarity sensitive relay fabricated of and controlled by, solid state components is provided to produce a more trouble-free and smaller device. The relay may be made in first and second versions, the first of which responds to input signals of a single polarity and the second of which produces first and second output signals in response to input signals of first and second polarities, respectively. The relays include first or second Wiegand modules each of which has a drive coil, an input signal coil and an output signal winding. The Wiegand modules are placed in a steady state magnetic bias and the drive coils pulsed at a predetermined frequency. When two modules are used, the input signal coils are connected in series and in a manner to produce opposite magnetic effects on their associated Wiegand modules.

Abstract: A mechanical foreign object detector upstream from the feed roll of a carding machine faithfully detects minute hard objects in the lap which could damage the lickerin or other components of the card. Spring-loaded detector pins penetrate through the lap and contact foreign objects on an apertured plate beneath the lap. Such pins rise and contact a wire connected in a stop motion circuit which immediately stops the operation of the doffer and the feed roll before any damage can occur. A visual and/or audible indicator alerts the operator to the presence of a foreign object or objects which the operator removes by hand before restarting the card by operation of a key-operated reset switch in the circuit. The mechanical detector apparatus includes a power drive which is synchronized with the operation of the feed roll of the card.

Abstract: A hollow core holder comprising a hollow cylinder with a passive cam locking element eccentrically rotatably mounted inside the cylinder such that a portion of the edge of the cam protrudes through a slot in the wall of the cylinder in one rotation status and is wholly within the cylinder in another rotation status. As the core holder is inserted into a hollow core, the cam comes into contact with the core, holding the core to the core holder until a release mechanism rotates the cam into the cylinder, out of contact with the core.

Abstract: The degradation of enkephalins in a mammalian host is inhibited by administration of an enkephalinase enzyme inhibitor of the formula ##STR1##

Abstract: A flange and casing insulation testing instrument, comprising a means to apply a small voltage across a pair of insulated pipe flanges or between an insulated pipe and casing in an environment of earth and ground moisture to effect an electrolysis charging between the two components. First and second timers are provided to record the time period required to effect charging to a predetermined level to allow the establishment of a data base relating to the system being monitored. A microammeter provides an indication of the state of the insulation between the elements of the system, i.e. if the flanges or pipe and casing are shorted together, there will be no residual charge.

Abstract: Sulfamoyl chlorides such as [(4,6-dimethylpyrimidin-2-yl)aminocarbonyl]sulfamoyl chloride are useful intermediates for the preparation of sulfamides and pyrrole sulfonamides which are useful as agricultural chemicals and particularly as herbicides.

Abstract: Composite fluorocarbon cation exchange membrane having at least two layers of fluorinated polymer containing pendant side chains with sulfonyl groups wherein the equivalent weight of one such layer differs from the adjacent layer by at least 100.

Abstract: A printed circuit board assembly fixture capable of securing the circuit board in a fixed relation to the inserting element of an electrical component inserting machine relies on the staking anvil of the assembly to precisely locate the circuit board and electromagnets to lock the circuit board in position for insertion of electrical components.
