Title: Electromagnetic device with current regulated closure characteristic
Inventor: HURLEY RICK ALAN
IPC: H01F7/18
Filed: 1995-07-27
Abstract: An electromagnetic switch includes separable contacts, an electromagnet having a coil which is energized to close and hold closed the separable contacts, a power supply for applying current to the coil, and a closed-loop control circuit for sensing and regulating, throughout a contact closure cycle, the current applied to the coil to a selected current reference.  The current reference may include a closing current reference for closing the contacts and a holding current reference for holding the contacts closed.  The control circuit may include a microcomputer for generating the current reference and, further, may include a first switching circuit and anassociated control circuit for actuating the first switching circuit between enabled and inhibited states, a second switching circuit and an associated control circuit for actuating the second switching circuit between conductive and non-conductive states, a feedback circuit for sensing the coil current and generating a related feedback signal, and a comparator circuit for comparing the current reference and the feedback signal, and for inhibiting the second switching circuit whenever the feedback signal is greater than the current reference. The microcomputer may include control signals defining states corresponding to a predetermined closing current reference and a predetermined holding current reference.  One of the control signals may attenuate the feedback signal, in order to provide the closing current reference. The electromagnetic switch may alternatively include a circuit for generating a time-variable current reference in order to substantially follow a predetermined magnet pull curve of the electromagnet.

Title: Antigen-antibody system specific for rheumatoid arthritis: the sa system
Inventor: MENARD HENRI A
IPC: G01N33/564
Filed: 1995-10-23
Abstract: RA  is  the most  frequent  and most  destructive inflammatory arthropathy. Rheumatoid factors, in spite of their lack of disease specificity,  are important serological markers for RA and appear important in its immunopathogenesis  as  well.   In  search  of  more disease-specific autoimmune systems, we have screened a human placenta .lambda.gtll  cDNA expression  library using selected sera from patients with classical erosive RA. We have identified one clone (RA-1) that is recognized by three of five screening sera. The 950-bp insert shows a complete nucleotide sequence homology to the cDNA encoding the two COOH-terminal domains of calpastatin. The deduced open reading frame of the RA-1 cDNA predicts a 284-amino acid protein, with a calculated mol wt of 35.9  kD.  Calpastatin  is  the  natural  inhibitor  of calpains, which are members of the cysteine proteinases recently implicated in joint destruction in rheumatic diseases. The two domains encoded by the RA-1 clone each contain the structural features associated with the inhibitory activity of human calpastatin. By Western blotting, 45.5% or 21/44 RA sera specifically recognized both the fusion and the cleaved recombinant protein. This is in contrast to 4.7% (2/43) in nonrheumatoid sera and 0/10 in normal sera. Anticalpastatin autoantibodies could represent a disease-associated marker in chronic erosive arthritis of the rheumatoid type and could hypothetically play a dual pathogenic role, directly via an immune interference and indirectly through an immune complex mechanism.

Title: Acoustic flow measurement method and measurement apparatus implementing the method
Inventor: HIISMAEKI PEKKA
IPC: G01P5/24
Filed: 1995-03-29
Abstract: The present invention relates to an acoustic measurement method of low measurement for the determination of fluid flow velocity (v), volumetric flow (Q) and/or mass flow rate (M) in a measurement pipe section (1) by way of determining over an exactly determined length (~a~b) the downstream propagation time TD and upstream propagation time TU for naturally occurring and/or artificially generated acoustic wave modes (15, 16) propagating upstream and downstream in a measurement pipe (1) section in the form of plane wavefronts at a low frequency. The pairwise opposed transducers (11, 12; 13, 14) mounted on the measurement pipe section (1) are configured by delaying, scaling and summing of the signals into at least two direction-discriminating filters of which one eliminates signals related to downstream acoustic waves while the other eliminates signals related to the upstream acoustic waves in the measurement pipe section (1). The output signals of direction-discriminating filters performing filtering in the same direction are compared with each other by forming a symmetrical equilibrium function with respect to their delay variable from a) the cross correlation function, b) the time integral of the squared difference, or c) the time integral of the squared sum, of the output signals, whereby one of the listed alternative functions is computed for acoustic waves in both downstream and upstream directions. These equilibrium functions are maximally symmetrical with respect to their maxima or minima when the direction-discriminating filtering is made properly and the correct values of the acoustic wavefront propagation times TD and TU for use in the computation of both the measurement result (v, c, Q and/or M) given by the method and the values of the delay time variables employed in the direction-discriminating filters are determined from these, maximally symmetrical equilibrium functions with the help of a certain, predetermined algorithm.
