The normal dosage of 10 grains (648 mg.) of aspirin, when combined with about 5 to 15, preferably about 10, grains of acetaminophen, yields increased blood levels of unhydrolyzed aspirin shortly and for extended periods after oral ingestion; a small addition of caffeine enables attainment of still higher blood levels of aspirin.

A device for the capacitive measurement of liquid levels, particularly in an automobile tank has a measurement sensor with measurement electrodes arranged concentric to each other forming a measurement capacitor, the space between the measurement electrodes communicating at a variable height with the liquid to be measured, and a channel within an inner of the measurement electrodes through which the liquid is drawn up. Compensation electrodes form a compensation capacitor in a suction path of th...

A method for manufacturing a bubble tube for a bubble level, comprising the following stages: completely filling a barrel-shaped machined cavity (9) in the tube with suitable liquid such that the entire hollow part of the bubble tube is full; positioning a plug (14), comprising a cavity of which the precisely determined inner shape corresponds to the required bubble volume, into the seat (13); joining the plug to the body of the bubble tube. Application: to the precision-manufacture of bubble tu...

The present invention provides a method of determining the concentration of a selected drug in the body of a subject comprising the steps of holding a liquid collecting means comprising an absorbent substantially inert member 1 in a position in close proximity to an eye 4 of the patient for collecting the fluid 7 therefrom; allowing the tear fluid collected to come into contact with reagent means 3 for reacting with said selected drug so as to produce, after a predetermined time interval, a phys...

An inverter receives an energizing voltage with a particular magnitude (e.g. 1.5 V) at a first terminal and produces the voltage at a second terminal. The received and produced voltages are differentially introduced to a stage which produces a single-ended bias voltage (e.g. 3 V) related to the second terminal voltage. The bias voltage is servoed to regulate the second terminal voltage (e.g. 1.5 V) and the bias voltage (e.g. 3 V) regardless of energizing voltage variations. In response to the bi...

A method for measuring the amount of an electroactive gas in a gaseous mixture using an electrochemical cell, the cell including a working electrode (anode), counter electrode (cathode), an electrolyte in which oxygen reduction is inhibited, means for applying a variable potential across the electrodes, and means for measuring current flow between the electrode, the method involving contacting the gaseous mixture with the anode, applying a potential across the anode and cathode and cycling the a...
