A vehicle tire gas mass sensor having a sealed cylinder containing a non-toxic and inert gas. The cylinder is sealed at one end with a diaphragm and contains a sealable plug at an opposite end for admitting the inert gas. Sealing is permanent after the introduction of gas. The diaphragm moves freely in response to pressure differential between the inside predetermined pressure of the inert gas and pressure existing in the environment in which sensor is installed. The sensor is defined by a first, second and third contacts which are responsive to diaphragm movement caused by pressure differentials in the cylinder. In turn opening and closing of the contacts actuates alarms for indicating such pressure differential. Equilibrium conditions as between the interior and environment of the sensor are reflected by the movement of diaphragm to compensate for temperature variation occurring at these locations.

Alarm system for monitoring pressurized vehicular tires for their gas mass, basically comprising a wheel unit for at least some of the tires of the vehicle, and a common receiver. Each wheel unit has an antenna made of a flexible material in the form of an open annulus, suitable to be snapped into and held by its resilience against the inner periphery of the respective tire, a continuous wire loop being embedded in the annulus for transmitting signals but optionally also for receiving power. At symmetrical location about the inside of the antenna, an electro-magnentic power generator module, a gas-mass monitoring sensor module, and a signal transmitter are mounted, electrically interconnected, for giving a preferably two-bit signal indication to the common receiver. The latter may have signal decoding and alarm circuitry to display at least two different conditions, namely a warning and an alarm condition. The transmitter modules in the wheel units and the common receiver may have circuitry for intermittently but continuously transmitting the two-bit signal so long as the gas mass monitored by the respective sensor module is within predetermined limits, the absence of one of the two signals being indicative within the receiver of the warning condition, while the absence of both signals results in the alarm condition.

An abrading and polishing tumbler apparatus in which the tumbler barrel is concurrently rotated and rocked includes an internally ribbed barrel having a separable closure cap at one end with a peripheral friction face and a closed opposite end face provided with a medial longitudinal projection having a pair of transversely spaced first and second longitudinal bores, respectively, concentric with and eccentric to the barrel central axis. A pivot pin is fitted in a selected bore. A support frame carries an upwardly directed raised open topped saddle bearing and a friction wheel is rotatably mounted to the frame below and longitudinally spaced from the saddle bearing. The cap friction surface rests on the friction wheel and the pivot pin rests on a saddle bearing. The friction wheel is rotated by a frame mounted motor to only rotate the barrel when the pivot pin engages the concentric bore and rocks and rotates the barrel when the pivot pin engages the eccentric bore.

An electromagnetic power generator for installation in the interior of a vehicular tire, working on the principle of deriving energy from the fact that a portion of the tire becomes flattened once every revolution, causing a change in the length of the corresponding chord. A small closed magnetic circuit is alternately opened and closed by this movement, by means of a flexible strap coupled between the tire interior and the magnetic circuit. The circuit is reclosed by magnetic attraction.

G01N 33/50

An in vitro methods of characterizing biliary excretion of a chemical entity using a single hepatocyte culture. Comprising providing cell culture comprising hepatocytes forming at least one bile canaliculus; contacting the cell culture with a first chemical entity for a time sufficient to allow uptake of the chemical entity by hepatocytes in the culture; disrupting the at least one bile canaliculus without lysing the hepatocytes and detecting the amount (if any) of the first chemical entity and/or a metabolite thereof released by the at least one bile canaliculus; and lysing the hepatocytes and detecting the amount of the first chemical entity and/or a metabolite thereof released by the hepatocytes.
