Abstract: A force sensing and transmitting mechanism (20) for a vortex flowmeter (10) which includes a force sensing beam (22) at one end, a force transmitting beam (24) at the other end, and a thin plate (26) joining the two together. The force sensing beam (22) is disposed in the passageway flow path (14) adjacent a vortex generator (42). The force transmitting beam (24) projects outside of the passageway (14). The adjoining plate (26) includes a central portion (28) fixed to the sensor beam (22) and the transmitting beam (24) and with outer plate edges fixed to the housing to provide a first pivot point. A second pivot point is provided at the opposite end of the force transmitting beam (24) and transducer means (62) are mounted at the second pivot point to detect rotational deflection of the force transmitting beam (24) corresponding to vortex induced pressure differentials. The second pivot point includes a rocker member (46) rigidly attached to the force transmitting beam (24) and having a V-shaped groove (52) in engaging contact mating with V-shaped projections (54) fixed to the housing. Rotational deflection of the force transmitting beam (24) tends to rockingly deflect the rocker member (46) on the V-shaped projections (54). Corresponding to vortex induced pressure differentials.

Abstract: Le procédé décrit, qui sert à produire un émission stimulée de rayonnement visible via le transfert rapide d'énergie intermoléculaire quasi résonnante, consiste à faire réagir une première vapeur métallique ou semi-métallique avec un réactif pour obtenir un produit de réaction à l'état excité métastable, puis à transférer l'énergie stockée dans l'état excité métastable du produit de réaction vers une seconde vapeur métallique ou semi-métallique, en utilisant le transfert d'énergie quasi-résonnante, afin de former des atomes récepteurs électroniquement excités selon une inversion de population par rapport à un niveau inférieur d'excitation des atomes récepteurs. Dans le mode de réalisation préféré dudit procédé, la première vapeur métallique ou semi-métallique est constituée par un élément de groupe IVA ou IIIB. La seconde vapeur métallique ou semi-métallique est choisie parmi les éléments de groupe IA, IIA ou IIIA suivants: scandium, yttrium, vanadium, fer, nickel, titane, chrome et étain, et le réactif est soit de l'ozone soit de l'oxyde d'azote soit du dioxyde d'azote soit un halogénure.

Abstract: Stretch wrapping packaging material on a load includes introducing stretch wrap packaging material (154) onto V shaped tips (110) of projecting portions (104) of a first grooved roller (102) so that the packaging material (154) spans the nonprojecting portions (106) of the first grooved roller (102). The web of packaging material (154) and the first grooved roller (102) are transported in the direction generally parallel to the grooves. The web of packaging material (154) spanning the nonprojecting portions (106) of the first grooved roller (102) is impinged with V shaped tips (210) of projecting portions (204) of a second grooved roller (202). The tips (210) of the projecting portions (204) of the second grooved roller (202) are transported at a speed which is less than the speed of the tips (110) of the projecting portions (104) of the first grooved roller (102). The tips (210) of the projecting portions (204) of the second grooved roller (202) moves at a speed which stretches the web (154) between the first and second grooved surfaces in a direction transverse to the direction in which it is transported and minimizes any stretching of the web in the direction in which the web is transported. The web is stretched between the projecting portions of the first and second grooved rollers (102,202) in a direction transverse to the direction in which the web is transported. The web is separated from the first and second grooved surfaces and wrapped onto a load (101) by providing relative rotation between the load and a dispensing mechanism (100) for the web.

Inventor: DENT PAUL WILKINSON
IPC: H04B1/64
Filed: 1991-05-28
Abstract: The invention relates to a device and a method for processing an analog input signal (S) which varies widely in amplitude, such as speech, for the purpose of reducing the ratio of maximum to minimum amplitude variations of an output signal (P), after the processing, to the square root of the ratio existing before processing in order better to transmit said signal through a channel of restricted dynamic range in the presence of additive noise. 
     The device comprises an analog-to-digital converter (2) arranged to change the input signal (S) into a stream of integer numbers (Nl,N2,N3..). The numbers in the stream represent in some proportional way the instantaneous value of the input signal (S) divided by a reference voltage (R). This reference voltage (R) is generated by a smoothed amplitude measuring device (4) in proportion to the amplitude of the output signal (P) that is produced, when the number stream is reconverted to an analog signal waveform by means of an digital-to-analog converter (6) working with a constant reference voltage. 
     The invention also relates to a device and a method for processing a signal of compressed amplitude variation, such as might be produced by the method and device described above, in order to produce a signal of amplitude variation restored to the normal range, being the square of the compressed range.
