Title: Ethanolic fermentation of substrates with a high sugar content - with initial maintenance of acidic conditions to minimise bacterial infection
Inventor: PIERRE-OLIVIER COGAT
IPC: C12P7/06
Filed: 1992-10-28
Abstract: Ethanolic fermentation of substrates with a high sugar content is effected by a process in which: (a) all of the water necessary for the process is introduced at the start; (b) all or most of the acid required for fermentation is added to the water at the start; (c) recycled or fresh yeast is added to the aerated acidified water and maintained in contact with the water for a time sufficient for acid treatment of the yeast; (d) the yeast is allowed to grow under aerobic conditions; (e) recycled vinasse is added, where possible, after the growth stage; and (f) the undiluted substrate is added during the growth stage and subsequent fermentation stage. ADVANTAGEU} The risk of bacterial infection is minimised by maintaining acidic conditions in steps (b)-(d). PREFERRED PROCESSU} The substrate is, e.g., molasses, juice or syrup derived from sugar beet or sugar cane, or a conc. hydrolysate derived from cereals. The acid is conc. H2SO4 and is added in an amt. of up to 3 g/l to maintain a pH of 1.85-2.2 in step (c) and 2.8-3.2 in step (d). The yeast is added as a `cream' not subjected to double centrifugation. @GRAPHIC = O:\EDNA\IMAGES\9429\FR\2697266.A1\PG000001.TIF,417,185,0

IPC: G01D5/26
Filed: 1993-04-02
Abstract: The device for interferometric measurement in polarised light comprises at least one so-called interferometric fibre-optic pressure sensor receiving the linearly polarised incident light vibrations delivered by a laser diode coupled to a linear polariser, and a photodiode detecting the analysis signal coming from the measuring fibre and passing through a crossed analyser. It is characterised in that it comprises an optical link (7) made of conventional single-mode fibre for remote transmission of the linearly polarised light vibrations and of the analysis signal and in that the linear polariser is a polariser/polarisation modulator (2) which rotates the polarisation state of the polariser at a high frequency which is greater than a maximum possible response frequency of the sensor.

Title: Appareil de détection d'espaces entre étiquettes pour imprimante thermique et procédé de commande dudit appareil.
Inventor: FOX DUANE M
IPC: B65H7/14
Filed: 1993-05-21
Abstract: L'invention concerne un appareil et un procédé pour détecter les espaces (52) entre des étiquettes collées à une matière dorsale (46) en des positions longitudinalement espacées pendant que la matière dorsale parcourt le trajet d'impression (38) d'une imprimante thermique (20). Une rangée de diodes électroluminescentes (136) orientée perpendiculairement au trajet d'impression (38) illumine la matière dorsale. Une fibre optique (140) détecte la lumière traversant la matière dorsale et transmet ladite lumière à une photodiode (225). La photodiode (225) produit un signal électrique analogique indicatif de la quantité de lumière transmise, qui varie en fonction du fait que la lumière a traversé seulement la matière dorsale ou a traversé à la fois la matière dorsale et les supports d'impression qu'elle véhicule. Le signal analogique est converti en un signal numérique qui est traité par un microprocesseur afin de contrôler et de commander l'avance des supports d'impression et de la matière dorsale à travers l'imprimante.

Patent FR-2712334-A1 (FR)
Inventor: PASCAL RAMBAUD
IPC: E01F9/627
Filed: 1993-11-10
Abstract: The support post (1) for a barrier for protecting against falling rocks includes a shaft (10) bearing on the ground (2) at its foot, and a base (11) on which the shaft (10) is fixed rigidly by means of gussets (15). An attachment rod (5) is driven substantially perpendicularly into the ground as far as an anchor (4) (cement block), according to the so-called exploded pile technique, and passes through a central region (11b) of the base. A coil spring (13) is threaded onto the rod and is held in compression by a nut (14). The base thus bears on the ground (2) by means of prestressing of the spring (13). The lateral forces on the post (1), resulting from the impact of rocks on the barrier, are compensated for by tilting of the base (11) about a tangent to its periphery (11a), against the compression of the spring (13). The stresses on the post are therefore damped, and positioning of the post requires only a single anchoring point.

Title: Die for bonding padding to covering member in vehicle seat
Inventor: SHIMADA MAKOTO
IPC: B29C63/22
Filed: 1994-03-18
Abstract: The die includes an upper die comprising a main die portion and a movable die member connected hingedly to it. The movability of such die member allows easy securement of the foam padding to the upper die, as the movable die member is easily inserted into the hollow of the padding, thereby allowing further insertion of the upper die on the whole into within the padding.  When pressing the padding against the covering member by use of the upper die, the movable die member is moved within the padding to a position on the same horizontal line with the main die portion, giving a pressure evenly both padding and covering member for effective bonding of them.
