Patent EP-0103577-A1 (EP)
Inventor: DANIELSSON OVE
IPC: D21J1/00
Filed: 1982-10-28
Abstract: Procédé de production de carton de fibres selon le procédé par voie humide dans un système fermé de retour d'eau. Des copeaux d'un matériau contenant de la ligno-cellulose, après défibration en pulpe, sont mis en suspension dans l'eau de manière à obtenir une suspension de pulpe pour former des feuilles mouillées dont on extrait l'eau par compression avec apport de chaleur, l'eau exprimée étant renvoyée à l'étape de suspension. On extrait mécaniquement l'eau de la pulpe obtenue dans la défibration, et la solution aqueuse obtenue de substances organiques libérées pendant l'étape de défibration est utilisée pour l'imprégnation des copeaux avant la défibration, cette substance se liant ainsi dans la pulpe.

Abstract: Hydrogen fluoride is separated from the organic constituents of a reaction mixture in the process for preparing 1-chloro-1,1-difluoroethane by the fluorination of methyl chloroform. A portion of the reactor bottoms is removed and the HF and volatile organics are vaporized from the reactor bottoms or "tars". The HF and volatile organics are then combined with the product stream from the reactor, and the resulting combined stream is cooled such that two liquid phases are obtained. One of the phases contains primarily HF and the other phase contains primarily 1-chloro-1,1-difluoroethane.

Abstract: In a cooling-water container (37), made of thermoplastic material, for motor vehicles, having a float (33) which triggers a reed switch (41) by means of a magnet (34) fitted therein, in order to indicate that the fluid level has fallen below an adequate level, the guide for the float (36) (which is formed, for example, from a cylindrical mandrel (35)) and the holder for the reed switch (41) are formed directly in the lower part of the container, e.g. in its base. The holder for the reed switch can thus consist of a blind hole (42) in the cylindrical mandrel (35). The largest diameter of the float (33) is smaller than the unobstructive width of the filler opening (36) and its release from the cylindrical mandrel (35) is prevented by a rivet-shaped stop (38) whose shank (39) is pressed into a blind hole (40) in the upper part of the mandrel (35). A collar (43) surrounds the open end of the holder for the reed switch (41) and prevents the penetration of water leakage. The permanent magnet is provided in the upper part of the float (33) and its drive is dimensioned such that the permanent magnet is always located above the water level (44). <IMAGE>

Abstract: A disc brake incorporates a fixed support (11), a caliper (17) incorporating a hydraulic actuator and sliding on pins (14 and 15). Friction pads (16) incorporating back plates (42) are also guided by extensions (24 and 34) of pins (14 and 15). Pin (14) transmits the whole of the brake torque from the pads (16) to the fixed support (11) due to an elongated aperture (44) in which the pin (15) engages. Pin (14) is designed to take the whole of this brake torque whereas pin (15) is designed to be readily removable. Flats (23) on pin (14) together with an opening (40) in the aperture (43) of each back plate (42) facilitate disengagement of brake pads from pin (14) when the caliper and pad assembly is swung away from the disc after removal of pin (15).

Abstract: © Installation thermoélectrique du type «pompe à chaleur» dans laquelle les thermoéléments 1 et les échangeurs 2 et 3 sont empilés pour former des colonnes, elles-mêmes assemblées pour former un tiroir. 
     Les nappes d'échangeurs 2 et 3 délimitent deux conduits de circulation d'un fluide chaud et d'un fluide froid. Ces conduits sont situés en dehors des axes d'empilage des colonnes afin que les échangeurs adjacents puissent tourner l'un par rapport à l'autre. Les thermoéléments et les échangeurs sont en contact par au moins une face à profil cylindrique ou sphérique. 
     Ce montage permet un serrage correct des colonnes donc un bon contact entre échangeur et thermoélément sans destruction des thermoéléments.

Abstract: @ An electrolyte containing 65 g/l zinc and 150 g/l Cu is purified in zinc, that is, the copper is removed, by causing the electrolyte to fluidise a bed 8 of ½ mm copper particles. The bed is fluidised by 25% to make it 42 cm deep. An anode 11 is disposed above the top of the bed. A cathode 9 is disposed part-way up the bed. Copper is electroplated onto the bed particles. Any zinc which may be eletroplated onto the bed particles tends to redissolve with concomitant cementation, on the particles, of copper, which can be recovered. The electrolyte is thus eventually completely stripped of copper and can be used for zinc electrowinning.

Abstract: A control system is provided for controlling the average power from an alternating voltage source (10) to a load (14) having inductive properties. The system uses a synchronous switch (16) shunted by a capacitor (20) connected between the source (generator) and sink (load) to pulse duration modulate the AC voltage carrier wave. A control signal generator circuit (19) drives the synchronous switch (16) such that the switch is closed at a variable time early in each half-wave of the AC voltage source carrier wave and such that the switch is opened at a subsequent later, variable time during that half-wave. This is accomplished by sensing the voltage across the synchronous switch in order to inhibit closing of the switch early in the half-wave until the synchronous switch voltage (and thus the voltage on the capacitor) is substantially zero and then opening the synchronous switch at a point in time to give the desired volt-second area between closure and opening within each half-wave.
