Title: A rotor type flow meter with optical detection
Inventor: TEUNISSEN THEODORA ANTONIA
IPC: G01F1/115
Filed: 1992-11-13
Granted: 2002-09-10
Abstract: The flow meter has in a substantially cylindrical inner housing (1) a helically designed diffusor (4), which imparts a swirl to the medium flowing through the inner housing. Downstream of the diffuser there is rotatably mounted a rotor (8), which has blades (13) extending from its rotational spindle (9) as well as a ring (14) which connects the blade ends to one another and is coaxial to the spindle. The rotor (8) is set in rotation by impingement of the blades (13) by the flowing medium. On the outer circumferential surface (15) of the ring (11) there is on a circular line a multiplicity of markings (16) arranged at equal angular intervals from one another. Through a window (18) in the inner housing (1), a light beam strikes the outer circumferential surface (15) of the ring (14), provided with the markings (16). Upon rotation of the rotor (8), the sequence of the. markings is transmitted by an optical-fibre cable (20) and sensed by a sensor (21), so that from the signals received the flow rate can be determined. The flow meter has the advantage that the medium to be measured does not have to be transparent as in the application of the light barrier and that the multiplicity of markings allows an increase in the measuring accuracy.

Abstract: A hook for gripping chain is asymmetrical so that the effective chain length can be adjusted to a part link tightness. The attachment end of the hook is offset from the plane of the hook end, which includes the slot for receiving a link of a chain. If the chain enters from one side of the hook, the chain and hook nave a different angle than when the chain enters from the other side of the hook. The resulting change in angle and hence the way the hook interferes with the chain changes the length of chain required for the chain to reach the slot.

Abstract: A technique for correcting the sampling time and carrier frequency error in a receiver for digitally modulated signals. Discrete-time, complex-valued samples of the incoming signal are fed to a pair of non-linear operators such as correlators. The first correlator provides a signal having a first phase component related to the symbol timing error and a second phase component related to the carrier frequency error. The second correlator provides a signal having a first phase component related to the symbol timing error and a second phase component related to the negative of the carrier frequency error. The phase components are then separated and detected to extract an estimate of the symbol timing error and the carrier frequency error. In the preferred embodiment, the complex-valued samples are frequency-shifted, before being fed to the correlators, so that the phase components of interest appear at zero frequency. The invention satisfactorily demodulates transmitted digital signals in applications, such as cellular time-division multiple access (TDMA), where they are susceptible to multipath fading.

Granted: 2000-09-26
Abstract: A perishable good integrity indicator includes a first oscillator for outputting a first clock signal which does not substantially vary in response to temperature. A second oscillator outputs a second clock temperature which varies as a function of temperature. A counter counts the pulses of the second clock signal during a time period determined by the first clock and outputs a count value. A data table receives the count value, translates the count value into a time temperature value representing the relationship of time and temperature during the time period and outputs the time temperature value to an .adder.      The adder adds the time temperature values output by the data table over time and outputs a cumulative time temperature value corresponding to shelf life for a product.

Abstract: A 1.2 kb fragment of the 5' regulatory region (from bp -1107 to + 100) was fused to the GUS (.beta.-glucuronidase) reporter gene and BN115-promoted GUS expression was observed in green tissues of transgenic Brassica napus plants only after incubation at 2°C. No expression was observed after incubation at 22°C, either in the presence or absence of abscisic acid.    Microprojectile bombardment of winter B. napus leaves with a BN115 promoter/GUS construct yielded similar results and was used to analyze a series of deletions from the 5' end of the promoter. Results obtained from transient expression studies showed that the low temperature regulation of BN115 expression involves a possible enhancer region between bp -1107 and -606 and a second positive regulatory region located between bp -302 and -274. Deletion analyses and results from replacement with a truncated CaMV (cauliflower mosaic virus) 35S promoter suggest that the minimal size required for any maintenance of low temperature GUS expression is a -300 by fragment. Within this fragment are two 8 bp elements with the sequence TGGCCGAC, which are identical to those present in the positive regulatory region of the promoter of the homologous Arabidopsis cor15a gene and to a bp core sequence in the low temperature- and dehydration-responsive elements (LTREs and DREs) identified in the promoter regions of several cold-responsive Arabidopsis thaliana genes. Mutation of either one or both of the GGCAC core sequence of the putative LTRE's to AATTC resulted in loss of cold-inducible gene expression, providing for the first time, direct evidence that CCGAC is required for low temperature expression.      Furthermore, replacement of an enhancer region (-605 to -1107) of the promoter with a more active enhancer from the 35S constitutive cauliflower mosaic virus (CaMV) promoter resulted in a "hybrid" promoter with increased low temperature induced activity several fold over that of the native promoter.
