Zinc serum and tissue levels are enhanced by therapeutic administration of certain .alpha.-mercapto-.beta.-aryl acrylic acids.

A method of monitoring the contact resistance in a film of an aluminum-based metal deposited on a silicon substrate in a vacuum chamber is provided wherein a reference wafer containing contact resistance measurement circuits is utilized. A significant number of contact resistance measurements is utilized to determine the impurity level in the film and/or to predict the post alloy contact resistance distribution from pre-alloy values.

Novel pharmaceutical compositions containing as the active ingredient the compound 5-methyl-1-phenyl-2-(1H)-pyridone are described. Such compositions have been found to have a metabolic property which causes significant lowering of serum glucose levels in humans and other mammals. The compositions containing 5-methyl-1-phenyl-2-(1H)-pyridone caused no irritation on oral administration or when applied to specific target tissues showed no significant irritation or other sequelae.

A system for indicating the stop levels for an elevator car in a hoist shaft so as to transmit signals to the elevator machinery when a selected stop level is approached. Vertically aligned pins are provided projecting from the wall of the hoist shaft; at least one pin being provided for each stop level. The pins extend into the path of the arms of the a cross, fixed to one end of a shaft journaled in a box which is attached to the outside wall of the elevator car and cause the cross and shaft t...

A novel collet and chuck are disclosed for applying high levels of torque to an article having substantially circular cross-sections about a common axis and sloping sides, such that it cannot be readily gripped by conventional chucks without marring the exterior surface of the article. A collet is provided which is reinforced against torsional distortion and which provides a rubber interior surface conforming to the article. Torque levels as high as 1700 inch-pounds may be applied to such articl...

A wire wound resistor is vertically disposed in a vessel. The resistor has a former of between 20 mm and 45 mm diameter and resistance wire of a resistance of between 1 and 4 ohms per turn connected in the circuit of an A.C. bridge circuit. Impedance change is indicated on a display unit calibrated to indicate the change in level of liquid e.g. milk in the vessel. The resistance wire is laid on the former by applying ultrasonic sound energy to soften the former which is of polysulfone or polycar...

A diagnostic device is described employing a solid, rigid diagnostic substrate (having as a part thereof an exposed layer of first immunologically reactive biological particles) in combination with means spaced therefrom for containing a solution of second immunologically reactive biological particles specific to the first particles. Preferably these elements are arranged with the layer of first immunologically reactive biological particles on a glass slide having a metallized surface and facing...

Intracellular mineral concentrations are obtained from very small tissue samples, such as sublingual tissue smears. The tissue smears are subjected to excitation radiation, typically a scanning electron beam, and mineral analyses may be based on the profile of emitted x-ray fluorescence. A number of correlations are made between various diseased states, susceptibility to diseased states, metabolic status based on the elevated and depressed levels of some or all of the mineral concentrations.

Disclosed is a method of lowering the prolactin level in the blood or serum of a person which method comprises administering a therapeutically effective amount of 2-amino-6-allyl-5,6,7,8-tetrahydro-4H-thiazolo-[5,4-d]azepine or a non-toxic, pharmaceutically acceptable acid addition salt thereof.

Heat is used to determine liquid level in a storage tank. An elongated heater that produces heat uniformly along its length is mounted vertically on the outside surface of the tank to extend substantially the full height of the tank. An elongated thermopile having a multiplicity of hot and cold junction pairs uniformly spaced along its length covers the heater so that heat from the heater travels in two different opposite directions, namely a first portion of the heat travels from the heater thr...
