Title: Sophisticated process for the production of alkyl (meth)acrylates by direct esterification
Inventor: FAUCONET MICHEL
IPC: C07C69/54
Filed: 1994-01-26
Granted: 1998-06-23
Abstract: An alkyl (meth)acrylate is prepared by a direct esterification (in 1) of (meth)acrylic acid by the corresponding alcohol, catalysed by H2SO4. The crude reaction mixture (B1), comprising the targeted ester, alcohol, (meth)acrylic acid, alkyl acid sulphate (alkyl hydrogen sulphate) and traces of H2SO4, is treated (in 3) with a base in order to neutralise the acid species, the resulting salts passing into the aqueous phase (A1), which is separated from the organic phase (O1) containing the targeted ester. The light products (L1), containing the alcohol, are recovered (in 4) from the aqueous phase and the waste water (E2) is discarded. The alkyl acid sulphate present in the aqueous phase (A1) resulting from the separation carried out after the neutralisation (in 3) is hydrolysed (in 8) to form, in this phase, alcohol and H2SO4, the acid species resulting from the hydrolysis are neutralised by introduction into the medium of a base and the resulting aqueous phase (A3) is sent to the alcohol recovery stage. Pollution of the waste water (E2), attributable to the alkyl acid sulphate, is thus avoided. <IMAGE>

Patent CA-2132006-C (CA)
Inventor: JASIUK MARK A
IPC: G10L19/12
Filed: 1994-01-18
Granted: 1998-04-28
Abstract: Analysis by synthesis calculates a difference by subtracting (130) synthesized speech from input speech. The synthesized speech is formed by exciting long and short term filters (124,126) with excitation vectors from a codebook store (114) which is searched by codebook generation (120). A weighting filter (132) is applied to the difference signal and the weighted difference is used to calculate an energy measure (134) which is used to control the codebook search (140). The weighting filter is an Rth-order filter controlled with calculated coefficients. The method for calculating coefficients models the frequency response of L Pth-order filters by a single Rth-order filter, where the order R ~ LxP. This method increases the control of a speech coder filter without an increase in hardware complexity.

Patent CA-2136232-C (CA)
Inventor: NOE ERNST-LUDWIG
IPC: G01R31/00
Filed: 1993-05-18
Granted: 2001-07-31
Abstract: In switching devices in which current contacts are made by actuating a magnetic armature, the test may include an analysis of vibrations or sound emitted in operating conditions. According to the invention, the sound emitted by the switching device when it is actuated is detected by a sensor and transmitted to an evaluation device for the discrimination of the time and/or frequency curve of individual sound components. It is possible in particular with the proposed process to discriminate between the sound signals produced by the making of the contacts and the armature. In addition, a sound analysis in the suitable time range permits a classification of any faults in the switching device. Finally, with particular reference to its application to flashing signal relays, it is possible to obtain an objective determination of the "proper sound" of the relay. In all cases it is especially the high sound components which are evaluated.
