Pilosine compounds are received by extraction from the leaves of Jaborandi Microphylous. Dermatological preparations containing a pilosine compound as an active ingredient and the method of treating various diseases of the skin and scalp by application to the afflicted areas of such a dermatological preparation.

A drilling fluid pressure recording system which produces a digital readout and a dual trace on a chart strip recorder which has a design accuracy of .+-.4 psi for up scale recording to 4,000 psi full scale. An analog electrical signal is converted into a five order digital signal and the digits reconverted back into two analog signals that are displayed on a dual pen strip chart recorder to provide both coarse and fine traces of the pressure. With both traces on the same chart, the result is a ...

A method of detecting focusing conditions used for optical machinery is disclosed. The focusing conditions of an optical image projected onto photodetector arrays arranged on both sides of the focal plane with a certain optical distance are detected based on an evaluation function representing a sum of absolute values of differences between output signals of adjacent photodetectors. When a value of a first evaluation function represented by the largest absolute value is less than a predetermined...

The apparatus provides a method of observing a water sample that is caused to flow rapidly past a beam of light of rectangular cross section. Attenuation of the beam by the sample is measured in a first detector that generates an output signal that has a basic, relatively slowly changing (e.g. half a second) component representative of the overall turbidity of the sample, and a series of short (e.g. 6 millisecond) pulses caused by individual, larger particles in the sample. The basic component i...

An apparatus for analyzing the biomechanical behaviour of the cardiac muscle and for diagnosing pathological conditions of the heart. The apparatus measures and records the rise and fall of intra-ventricular pressure monitored by a transducer installed in a cardiac catheter or in an arterial probe. The pressure versus time recordings during both the systolic and diastolic phases are mathematically analyzed, and two parameters indicative of the biomechanical conditions of the muscle are derived. ...

In a method of assessing drilling conditions during a drilling operation measurements of torque applied (TOR), weight on bit (WOB), rate of penetration (ROP), and rotation speed (ROT) are gathered. Computed therefrom is a history (60, 61) of points (x, y) where x=(TOR/WOB) and y=(ROP/ROT).sup..gamma. : .gamma. being a derived constant indicative of down hole geometry. Trends in this history are monitored to assess drilling conditions. For example in soft plastic rock migration 62 towards the ori...

A method is disclosed for treating an ischemic condition. The method comprises coadministering topically and internally a vasodilator to a patient having the condition for treating said condition.

Anaerobic conditions are produced in a main chamber having selective communication with a lock chamber from separate supplies of anaerobe nurture gas, inert gas and oxygen-consuming gas. Flushing is from the lock chamber and oxygen-consuming gas is supplied only after flushing and first, if not only, to the lock chamber.

A process for diagnosing abnormal spinal conditions. The process utilizes the step of placing the patient in a draft-free room and uniformly spraying the patient with an evaporative liquid. After a waiting period, the surface skin temperature is measured and areas of above or below normal skin temperature are mapped.

A freezer alarm sensor has a body in which there is an elongated vertically extending chamber. Contactors connectable in an alarm energizing circuit, normally insulated from one another, are exposed in the chamber, near one of its ends and diametrically opposite one another. A current conducting slider is freely slidable in the chamber between a raised position spaced from the contactors and a dropped position engaging the contactors and electrically connecting them. The chamber is partially fil...
