Inventor: DI NUNZIO VITTORIO
IPC: G01F23/24
Filed: 1994-03-23
Abstract: The circuit (CS) comprises a capacitor (C2) intended to be connected to the output (Nm) of the level sensor (T) via a resistor (R1) in such a way that in use the voltage of the said capacitor tends to follow the variations of the output voltage of the sensor (T) with a predetermined time constant and a voltage controlled current generator (OP1) the output and a first input of which are intended to be connected to the sensor (T), with the second input connected to the said capacitor (C2). This generator (OP1) is arranged to provide at its output a substantially zero current when the potential difference between its inputs is substantially zero and a current the magnitude and sign of which depends upon the magnitude and sign of the said potential difference when it is different from zero, this current tending to oppose variations in the voltage which,in operation, are applied to the first input of the generator (OP1)

Abstract: A video source (202) provides a temporally interpolated video signal (YT), a spatially interpolated video signal (YS) and a motion indicating signal (MOT). A difference signal (DIFF), derived from the temporally and spatially interpolated signals, is symmetrically limited (252) as a function of the motion signal amplitude and then combined with the temporally interpolated signal to form a motion adapted video output signal (Yest) having (1) reduced motion artifacts such as smearing and loss of fine detail; (2) reduced noise sensitivity; and (3) enhanced low-contrast motion rendition.

Abstract: Alkoxynaphthalenecarboxylic acid is produced by a process comprising the addition of 1,3-butadiene to alkoxyalkylbenzene to yield an adduct. The adduct is cyclized in the presence of an acid catalyst to alkoxyalkyltetralin. The tetralin derivative is then dehydrogenated to produce aloxyalkylnaphthalene, which is oxidized to alkoxynaphthalenecarboxylic acid.

Abstract: The invention discloses a separating and aligning device (10) which receives differently sized articles (A, B) in any given sequence and position and which uses a multiplicity of webs (11, 12, 13) which are located side by side and each exhibit driven article-transporting rollers (20, 22, 23) having different speeds, the speeds being uniform over the length of the webs (11, 12, 13), but steadily increasing, in each web (11, 12, 13), to one side of the separating device in order to produce a lateral speed increase. The speed increase produces a separation and rotation of the articles (A, B) and this results in the fact that they are arranged in a single row along one side (40) of the surface of the separating device (10) and can thus be discharged onto a conveyor (15) at the end of the separating device (10), which conveyor (15) is remote from that end at which the articles (A, B) are received. One or more webs (11, 12, 13) comprise rollers having a tapering diameter (J, K), in order to render the lateral speed increase uniform. <IMAGE>

Abstract: Inclusions in a liquid flow, such as air bubbles in a blood flow, are detected by transmitting a signal through the fluid and receiving and interpreting the received signal based on the expected degree of attenuation for the liquid and the inclusions. The amplitude of the transmitted signal is automatically adjusted to maintain a constant average amplitude of the detected signal, thus compensating for changes in the detection environment. The average amplitude of the transmitted signal is controlled by integrating the received signal using an integrator with a time constant longer than the time constant of the expected inclusion signals, and comparing the integrated signal to a constant reference level. 
     The presence of microbubbles is detected and a signal comprising a string of high frequency pulses is generated while the microbubbles are present. By counting the pulses, in conjunction with knowledge about the flow of liquid and the anticipated size of the microbubbles, an estimate of the total amount of air infused into the patient within a given time period is calculated. 
     A tubing holder for retaining a flexible tube in an inclusion detector has tubing retention grooves formed into tubing engagement faces, the tubing engagement faces being spaced closer together than the tube diameter. The tube is inserted into the tubing holder by compressing and deforming it against the tubing engagement faces, until it reaches the tubing retaining grooves.

Abstract: Method for characterizing a full color gamut of a digital photosensitive color proofing system having at least two separately controllable process parameters uses a one page color standard (100) for calibrating the full color gamut. The one page color standard (100) includes a plurality of color density test areas (110a-e) on the page, with each color density test area having a test patch for each colorant printed at a selected color density that is within a range of color densities, and a plurality of tone rendition test areas (102a-e) on the same page. There is one tone rendition area for each of the color density test areas, and each tone rendition test area has a plurality of test tints for each colorant as a primary color and a plurality of test patches for a set of secondary colors composed from combinations of the primary colors. The method for producing the one page color standard (100) includes the steps of adjusting a first process parameter to produce the plurality of color density test areas (110a-e), adjusting a second process parameter to produce the plurality of tone rendition test areas (102a-e), and then printing the single color standard or test pattern page. The characterization process of the present invention involves the steps of measuring selected ones of the test patches and test tints to define or characterize the full color gamut, including a primary color gamut, a secondary color gamut and tone renditions, for the range of color densities.

Date Aug. 4, 1994The present invention provides a process for the manufacture of a product essentially containing amylose from vegetable materials, in particular from peas. To this end, the flour is mixed with an alkaline decomposing agent, and then a separation into a liquid protein phase and a solid phase containing polysaccharide is performed. The solid phase is then re-suspended and subjected to several sifting steps, followed by at least one washing step and subsequently a drying step. From such polysaccharide material, in particular from amylose, any kind of moisture-resistent, flexible, and in particular biodegradable articles can be produced by means of conventional plastics technologies, in particular the injection molding technique. A particular advantage of the present invention resides in the fact that the thermoplastic polysaccharide material, which is produced from renewable raw materials, can also be processed into sheets which in turn can then be worked with conventional plastics techniques.

Abstract: A ball joint, which essentially consists of a ball (13) at the end of a ball rod (14), a lower ball cup (16) adjacent to the ball neck (19) and an upper ball cup (17) associated with the ball head (20), which contain the ball (13) between them so that it can slide, a ball (13) and ball cups (16, 17) and a casing (11) surrounding a closure cover (22) and a compression spring in contact under the cover (22) and holding the ball cups (16, 17) and the ball (13) in position, has the special feature that the upper ball cup (17) itself takes the form of a compression spring like a cup spring and is permanently in direct contact with both the cover (22) and the ball (13). Operating forces can therefore cause only a distortion of the compression spring but cannot cause two components not previously in position to strike each other. A further advantage lies in the simplified layout and the elimination of a component, for, in the invention, the upper ball cup is itself a compression spring, and the prior art spiral compression spring is no longer needed.

Title: Arrangement for a clutch in a vehicle transmission.
Inventor: JOHANSSON JAN
IPC: F16D13/74
Filed: 1994-04-13
Abstract: A clutch in a vehicle transmission is provided with an accumulator (13) which contains oil when the clutch transmits drive torque during normal operation. At the time of a clutch disengagement movement, the accumulator (13) is evacuated and the oil is transferred to the clutch housing (2), which is therefore filled with oil during clutch operation. After clutch operation, the oil returns to the accumulator (13), while the clutch housing (2) is evacuated of oil. This means that the clutch acts as a wet clutch during clutch operation and as a dry clutch during other operating conditions. The advantages of the respective types of clutch can be utilised without suffering their respective disadvantages.
