Title: Synthesis of mannojirimycin derivatives
Inventor: FLEET GEORGE W J
IPC: C07F7/18
Filed: 1990-09-07

IPC: H04L27/227
Filed: 1990-09-12
Abstract: ABSTRACT     A carrier recovery system combining a narrow band carrier phase estimater and a wide band carrier phase estimator, and a digital phase demodulator using this carrier recovery system.  The narrow band carrier phase estimator extracts a carrier phase having a low pulse slip rate from received signal.  This carrier phase, however, cannot track fast phase fluctuation due to fading.  On the other hand, the wide band carrier phase estimator tracks fast phase fluctuation due to fading, and extracts a carrier phase from the received signal.          From this carrier phase is subtracted the other carrier phase obtained by the narrow band carrier phase estimator, and the balance, after its fluctuating range is limited, is added to the carrier phase obtained by the narrow band carrier phase estimator, thereby making it possible to obtain a carrier phase which can track fast phase fluctuations due to fading without sacrificing the phase slip rate.  By using the carrier phase obtained in this manner, there can be structured a digital phase demodulator suitable for mobile communication systems based on coherent detection.  If carrier component is extracted by reversely modulating the received signal with reference signal obtained by subjecting to decision the signal demodulated by this digital phase demodulator, a carrier phase is recovered by filtering the extracted carrier component in a wide band, and the received signal is synchronously detected with this carrier phase, the error rate can be further reduced.

Abstract: TITLE FLAVORANTS FOR ENHANCING THE TASTE AND FLAVOR          OF BAKERY PRODUCTS                               INVENTORS PIERRE GÉLINAS ODETTE LACHANCE  JOHANNE AUDET                      ABSTRACT OF THE DISCLOSURE A process for producing bread flavorants is disclosed. The process starts with a mixture of milk and/or whey, water and optionally flour, sodium citrate, saccharose and yeast. The mixture is fermented at a temperature leading to the production of aroma substances and acids, typically in the 25-45°C range, using an inoculum which comprises at least one heterofermentative bacterial culture of Lactobacillus, e.g. L. casei subsp. rhamnosus and optionally one or more heterofermentative or homofermentative lactic bacterial cultures. These flavorants are added to bakery products at concentrations of about 2-4% (dry weight; flour basis) to enhance their flavour. At higher concentrations sourdough-type bread is obtained using a process substantially shorter than known processes. The resulting flavorant is stable when refrigerated and can be used in dried form.
