Abstract: A method for the direct condensation of gaseous food volatiles, such as coffee aroma, on a food substrate, such as coffee, at cryogenic temperatures. A bed of particulated solid substrate is placed in a vessel cooled by a cryogenic fluid such as liquid nitrogen. The substrate is fluidized to provide an adsorbent bed thereof. Gaseous aroma volatiles are then adsorbed onto the cooled and fluidized bed of substrate having a temperature preferably below -150°F (·101°C). The aromatized substrate formed is preferably equilibrated to insure uniformity of aromatization, binding of volatiles to the substrate and storage stability. The resultant aromatized substrate can then be added to unaromatized food material for aroma and/or flavor enhancement.

Abstract: Le generateur de tension en dent de scie est destine notamment a servir comme generateur de reference et de cadence pour la regulation electrique du chauffage d'un vehicule a moteur. Le generateur a une tension de sortie ayant un front de montee determine par un element RC et un front de descente determine par un autre element RC. Un element de commande constitue de preference par un amplificateur operationnel (10), est regule par un premier condensateur (C1) et la tension de sortie est decouplee par un autre condensateur (C3) ayant un circuit de decharge (R7). De cette maniere, la courbe de descente de la tension de sortie peut etre faconnee librement pour avoir une forme non-lineaire voulue, ce qui convient pour compenser la non-linearite des elements de l'objet du reglage. L'element RC qui determine la descente (C3, R7) est couple par une diode (D2) au premier condensateur (C1) du premier element RC. Les deux condensateurs sont donc susceptibles d'etre rapidement charges a travers la meme resistance (R5).

Abstract: A low capacitance pad structure (10) is disclosed for testing a semiconductor chip, so as to enable the accurate measurement of rise times and delays in internal logic circuitry. The structure provides a capacitive coupling between the internal logic circuit under test and the capacitance of the probe connected to the input/output pad of the chip. This is achieved by providing a coupling capacitance between the internal logic circuit and the input/output pad. The coupling capacitance (C o ) is formed by providing a thin dielectric layer (5) on top of an enlarged plate portion (1) of the conductor line (8) connected to the output of the internal logic circuit under test, so as to capacitively couple voltage swings on the line to a second level plate (4) which forms the electrode to be contacted by the test probe.

Abstract: Method and means for evaluating the quality of audio and/or video transfer characteristics of a device upon which, or through which, audio and/or video information is contained, or passes, respectively. Both method an apparatus concern the evaluation of the quality of information transfer in the recording and playing back of a recording medium or in the transferring of audio and/or video information through an information handling device referred to as a throughput device. Unit evaluation is accomplished by establishing an input signal of known content, measuring selected parameters of selected parts of the input signal, feeding the input signal to the unit under test, measuring the parameters of parts of the output signal from the unit under test corresponding to the same selected parts of the input signal, and comparing the selected parameters of the input signal with the corresponding parameters of the output signal. Whether monitoring the quality of the signal transfer characteristics of a throughput device, a magnetic tape containing program material, or a video disc, master disc or replica, a "signature" is created for the unit under test, and subsequent analysis of the unit as it progresses along a production line or of a copy made on the same or alternate recording medium results in a second "signature" which is compared against the first signature to make a determination as to the quality of the signal handling or transfer characteristics of the unit. In this manner, out-of-tolerance conditions can be automatically detected, thereby eliminating subjectivity and providing consistency in the quality level of device testing.
