Title: Method and installation for separating the solid and liquid phases of animal or vegetable organic materials
Inventor: DANIEL PESCHE
IPC: B30B9/06
Filed: 1993-02-19
Abstract: The method for separating the solid and liquid phases of animal or vegetable organic materials consists in subjecting the material to a dynamic compression with a view to removing the liquid phase from the solid phase during pressurised progression of the said material. This material is subjected to alternating cycles of compression and depression and it undergoes, advantageously, simultaneous operations of cutting up, grinding and heating. The invention also relates to the installation for implementing the method. Such an installation may be applied to the processing of by-products of meat, sea produce or vegetable materials for obtaining fruit juices.

Title: Hot dip coating of stainless steel with a tin@ alloy
Inventor: CAREY II JAY F
IPC: E04D5/04
Filed: 1993-03-24
Abstract: A method of coating a stainless steel substrate with a tin-based alloy coating to form a composite body comprises pickling the substrate to give a surface free from chromium oxide and hot-dip coating the surface with a tin-based alloy to give a coating 7 x 10 power (-3) 2.5mm thick. Also claimed is a composite body formed by the above process.     The thickness of the coating is not more than 5mm. The pickling soln. contains one or more acids such as hydrofluoric, sulphuric, nitric, hydrochloric, phosphoric and isobromic acids. Pref. the pickling soln. contains 5-25% HCl and 1-15% HNO3, pref. at 48-60 deg.C.. The surface of the stainless steel is treated with abrasive and/or absorbent prior to pickling. The chromium oxide-free surface is treated with a deoxidising agent such as zinc chloride to remove residual oxides. The surface is also rinsed pref. with oxygen-free water at at least 37 deg.C.. The hot dip coating is carried out in a flux zone and an alloy coating zone. The flux soln. contains 30-60 wt.% ZnCl2 and 5-40 wt.% NH4Cl. The tin-based alloy contains 90-99.9 wt.% Sn and not more than 0.1 wt.% Pb and may contain 0-7.5 wt.% Sb. A protective skin of e.g. palm oil may be provided on the coated substrate. The coated substrate may be treated with a weathering agent such as an asphalt-based or petroleum-based paint to accelerate the weathering and discolouration of the coating.

Patent FR-2703888-A1 (FR)
Title: Desk for reading or writing when lying down
Inventor: JOSEPH LE GOFF
IPC: A47B23/00
Filed: 1993-04-14
Abstract: The present invention relates to a device serving as a desk for reading and writing when lying or sitting. The need for this arises from the fact that holding a book or magazine in the hands in order to read while lying down, in bed for example, quickly becomes uncomfortable and tiring for the arms. The device comprises a desk (1) consisting of an open frame (2) approximately 40 cm wide by 25 cm high. Stretched horizontally across this frame from one upright to the other are two very fine nylon or steel wires (3). These hold the book in a vertical or inclined position. The book rests on a support (4) while the spine of the book is supported by a hinged plate (5) fitted with a return spring and a stop (6). In this position, the space between the book and the frame allows the fingers to be passed through the frame to turn the page. Once the page has been turned, the book and plate (5) are moved back on to the desk (1) and reading can be continued.
Patent FR-2705846-A1 (FR)
Title: Solid-state power transmitter operating in amplitude modulation
Inventor: MICHEL DURAN
IPC: H03F3/217
Filed: 1993-05-25
Abstract: The invention relates to solid-state transmitters operating in amplitude modulation. In a transmitter formed by identical solid-state amplifiers (A1-1 to A48-198) having their outputs in series, modulation is carried out, as a function of the instantaneous amplitude of the modulating signal (A), which consists in selecting (circuits 3, 4) a certain number of these amplifiers: some working at their rated level to give a first signal close, within a nominal level, to the desired signal, the others, by virtue of phase control, working at the rate of the modulated signal only for part of the time, this part of the time being a function of the difference between the first signal and the wanted signal. Application to solid-state power transmitters.
Patent FR-2694970-A1 (FR)
Inventor: DIETER OTTO
IPC: F16H59/36
Filed: 1993-08-23
Abstract: A process is disclosed for controlling a torque transmission system having a hydraulic torque converter (11) and a friction clutch (12) for bridging the hydraulic torque converter (11), as well as a bridging clutch and a hydraulic torque converter for such a system. This control process is a moment control in which the input torque supplied by a driving unit is subdivided into a torque to be transmitted by the converter (11) and into a torque to be transmitted by the lock-up clutch (12). In the briding clutch, the radially outer side of a ring piston centrally arranged between the converter lid and the turbine wheel is designed as a clutch disk and its radially inner side is received on a counter-sealing hub. The convertor is "soft" and has a flat primary characteristic curve and a broad secondary characteristic field, thus a large conversion range.

Title: Bistable du type SEED, tout optique.
Inventor: PAUL VOISIN
IPC: G02F3/02
Filed: 1993-08-26
Abstract: Des couches de semiconducteur (1) définissant une sur-structure PIN. Sa partie intrinsèque comprend une suite de couches formant des puits quantiques; elle est capable, dans une plage du spectre, d'absorption optique dépendante du champ électrique. On admet, dans la suite de couches à puits quantiques, une lumière de travail située dans ladite plage du spectre. La suite de couches à puits quantiques (SL) est au repos le siège d'un champ électrique auto-construit, en raison de la différence de potentiel engendrée naturellement à ses bornes par la sur-structure PIN. De leur côté, les paires électron-trou créées par l'absorption de photons modifient le champ électrique au repos. Le nombre, les natures et les géométries des couches de ladite suite (SL) sont choisis de sorte que l'absorption de la lumière de travail sous champ électrique, ainsi que le transport sous champ électrique des électrons et trous créés par cette absorption de lumière, aient un effet combiné auto-amplificateur quant aux variations d'absorption. Ceci procure un effet bistable "tout optique", sans nécessité de recourir à un circuit électrique extérieur.

Title: Medical prosthesis for insertion into leg bone to extend length
Inventor: GRAMMONT PAUL
IPC: A61B17/72
Filed: 1994-11-04
Abstract: The device comprises a stud (12) to be fitted within the bone marrow, consisting of a tubular sleeve (9) and an extension (11) which is able to slide within the sleeve. A wire (15) inside the stud links together two sections (17,18), each of which have external ribs which engage in corresponding internal ribs within the sleeve.The wire is made of a memory alloy which is biocompatible. The mechanical configuration is such that the compression force exerted by the memory alloy is transformed into a longitudinal force to move the extension out of the sleeve. Successive cycles of heating and cooling allow the stud to be extended by stages, with the ribs providing a ratchet action. A generator of low and very low frequency electrical signals is connected to a coil surrounding the limb within which the stud is fitted.

Abstract: The invention relates to a process for the fabrication of dense ceramic products based on silicon carbide, wherein a mixture of powders of SiC, Al3C4, AlN and Al2O3 is sintered with or without pressure by continuously raising the temperature with or without isothermal stage. During sintering, the densification is reached at a maximal temperature of 2020  DEG C, preferably a maximum temperature lower than or equal to 1950  DEG C. The composite ceramic product thus obtained has an original biphased structure which is comprised of a first SiC phase and a second cristalline phase consisting of a solid solution of AlN and Al2OC, the two phases being perfectly structurally compatible. The resulting ceramic products are usable particularly as thermomechanical ceramics or as binding phase for refractory material.
