4-(5,6,7,8-tetrahydro-5,5,8,8-tetramethyl-2-anthracenyl) benzoic acid marked with tritium is used as a radioactive marker in the titration of nuclear receptors and CRABP, in the measurement of the affinity of retinoids for nuclear receptors and CRABP, in the titration of known retinoids, the characterization of antibodies directed against 4-(5,6,7,8-tetrahydro-5,5,8,8-tetramethyl-2-anthracenyl) benzoic acid, and in the study of the distribution and metabolism of said benzoic acid derivative.
摘要:
A printing assembly having a guiding and driving system for moving an article past ink emission nozzles. A detecting device detects the movement of the article through the assembly and based on that detection triggers emission of ink by the nozzles. Compressed air jets are forced toward the article, creating suction due to the Bernoulli effect which effectively maintains the article a set distance from the nozzles.
摘要:
A wraparound type article carrier for use in connection with a plurality of articles comprising top, bottom and side walls interconnected to form a sleeve, a closure element preferably in the form of a sleeve enveloping one or more articles at one end of the carrier, the closure sleeve comprising a main panel and an auxiliary panel foldably joined along the upper edge thereof, and the auxiliary panel being angularly related to the main panel and extending inwardly of the carrier.
摘要:
A device for measuring the pressure of tires, particularly for aircraft, comprising a passive sensor adapted linearly to convert a variation in pressure into an electrical information variation, in situ, means adapted to convey the electrical information from the sensor to the cockpit of said aircraft, a self-oscillator whose oscillation frequency is controlled by the value of said electrical information from the sensor and means adapted to convert the signal issuing from said self-oscillator into a D.C. voltage proportional to a frequency variation, said frequency variation being proportional to said variation in pressure, characterized in that the electrical information from the sensor, before transmission into the cockpit, is applied to the terminals of the primary winding of a high frequency transformer, said primary winding being mechanically fast with the wheel, the secondary winding of said transformer being concentric with respect to the primary winding and mechanically fast with the stationary part of the landing gear, the ratio n of transformation between the primary winding and the secondary winding modifying the electrical information from the sensor according to the square of said ratio n.
摘要:
The invention relates to materials and method for forming composite packages comprising a first flexible material (11) and a second relatively rigid material (12) which are connected together without the use of additional connecting materials. The connection is achieved by causing the flexible material (11) to be deformed to cooperate in tension with interrupted zones (19) of the relatively rigid material (12). Many different packages may be formed for a variety of uses but the invention is particularly suitable for connecting a heat shrinkable plastic body part to a paperboard or like sheet material end part.
摘要:
A method uses portable objects where the reading and writing of data in the memory are free, owing to the writing in the latter, if necessary, of elements which can be prepared and verified only if secret information kept both in a secure memory at the control center and in a secure memory in the machine with which the transmission is carried out is known.

The invention relates to the production of a clay-impregnated substrate (10), including a step in which a pasty material (3), containing clay mixed with a liquid, is sprayed onto a substrate (1) having an aerated structure.
摘要:
A medical examination table comprises a pedestal to which an end of a rocker is hinged. An underframe is fixed rotationally to the other end of the rocker. By acting on the two axes of rotation, the table may enable motions that are as different as a simple raising motion and tilting motions of various amplitudes in one direction or another. The advantage of the invention is that it provides a simplification of the industrial-scale manufacturing of tables with or without a rocker.
