Patent EP-0258027-A2 (EP)
Inventor: GAUTREAUX MARCELIAN FRANCIS
IPC: B01J8/26
Filed: 1987-08-24
Abstract: A polysilicon process is disclosed in which the fines which are inherently produced in a fluid bed deposition type operation using silicon seed particles and a silane feed are in effect glued on to the product part­icles so as to reduce the undesirable effect of the silicon fines. The process comprises operating a fluid bed in two modes. In the first mode, high productivity is favored at the expense of producing fines which are produced by homogeneous decomposition of the silane feed. In the second mode, the fines are in effect glued on to the particles to which they are adhered by means of deposition of a thin layer of silicon. In the second mode, the concentration of the silane in the feed gases is reduced thus favoring hetergeneous deposition of the silicon on the silicon particles in the bed. The process can be operated using a single fluid bed reactor by alternating cycles or in a more continuous manner utilizing two fluid bed reactors, the first reactor being operated at the high productivity rate with the second reactor taking the silicon particles from the first reactor and operated at the gluing on conditions.

Abstract: A position sensing mechanism (88), for use with a nuclear fuel transfer system (50) which employs an underwater cart (42) having a pivotable container (44) to receive fuel assem­blies, employs mechanical elements below water and a cable (96),(100) which carries movement of the mechanical elements to a switch assembly (102) at a dry location. The mechanical elements include an anchor (70) element which is affixed to an upender mechanism, which selectively moves the container (44) between horizontal and upended positions when the cart is located at a fuel transfer station, and a feeler mechanism (83) which is displaced by the cart. The feeler mechanism includes a pivotably mounted swing arm (100) and one or more pulleys (90),(92). The cable is attached to the anchor elements and is guided by the pulleys. The switch assembly (102) includes a further pulley having cams to actuate microswitches when the cable is displaced by the anchor element and feeler mechanism. A temperature compensator (98) is spliced into the cable to keep its length constant despite temperature variations.

Abstract: The invention solves an improvement of method and apparatus for area-stretching of leathers which re inserted between two resilient belts with which they are alternatively and cyclically either moved (fed between a set of deepenings and a set of pulling studs, wither stretched by causing of reversible shifting (pushing-in) of said pulling studs into said opposite depenings. 
     The improvement is reached as follows: 
     Before beginning of each stretching cycle both the resilient belts, commonly with treated leather, are mutually clamped, one opposite to the other, at peripheral places of the deepenings and before the resilient belts subsequently shift, their clamping is released. Between pulling studs (21) there are mounted resilient plates (22) and oppositely to them, on peripheries of the deepenings (30), there are provided contact planes (31r) which are parallel to the shifting plane (o) of the resilient belts (4, 5). Except these distinguishing signs of the present invention there exist also further possible variances. 
     The present invention can be used for area-stretching of leathers.

Abstract: A process for the production of dihydric phenols is disclosed which comprises 
oxidizing diisopropylbenzene (DIPB) with molecular oxygen to obtain a reaction mixture (A) comprising at least diisopropylbenzene dihydroperoxide (DHP) and diisopropyl­benzene monocarbinol monohydroperoxide (HHP), the DIPB, DHP and HHP being optionally substituted; 
supplying to an agitation reactor (1), an oily phase comprising a solution of the reaction mixture (A) in an aromatic hydrocarbon solvent, and (2), an aqueous phase comprising hydrogen peroxide and an acid catalyst at a feed rate of 1 - 5 moles of hydrogen peroxide per mole of HHP in the reaction mixture (A), the acid catalyst being present at a concentration in the aqueous phase of 10 - 40% by weight, the concentration of hydrogen peroxide in the aqueous phase being at least 20% by weight, and the weight ratio of the oily phase to the aqueous phase being at least 10:1; 
allowing the HHP to be oxidised by hydrogen peroxide into the corresponding DHP at a reaction temperature at 30 - 60°C so that a reaction mixture (B) is obtained; 
separating the aqueous phase from the oily phase in the reaction mixture (B); and 
  subjecting the DHP in the separated oily phase to acid cleavage to form the corresponding, optionally substituted, dihydric phenol. 
     The process represents an improvement over prior art processes in that it allows removal of the reaction water and recirculation of the aromatic hydrocarbon and the aqueous phase to be dispensed with whilst allowing a higher ratio of oily phase to aqueous phase to be achieved. This reduces the amount of hydrogen peroxide and acid catalyst needed, thereby decreasing the reaction time.

Abstract: An input supply voltage is coupled via a primary winding of a flyback transformer to a collector of a chopper transistor switch that operates at a given frequency. During a portion of each period when the chopper transistor switch is conductive, a second switch applies a short-circuit across a secondary winding of the transformer at a controllable instant that causes the emitter current of the chopper transistor switch to increase at a significantly higher rate. When the emitter current exceeds a predetermined threshold level, a one-shot arrangement is triggered. Consequently, a pulse is produced that turns off the chopper transistor switch and that maintains it nonconductive for the duration of the pulse. A flyback pulse produced in a winding of the transformer is rectified to produce a DC output supply voltage. The length of the interval when the chopper transistor switch is conductive is controlled by the second switch in accordance with the level of the output supply voltage in a negative feedback manner for regulating the output supply voltage.

Abstract: Permanent domain refinement of grain oriented electrical steep strip (16) is obtained in a high speed two-stage process. The process removes the glass in narrow regions (17) which just expose the base metal. An electrolytic etch is then used to deepen the regions (17) into the base metal and minimize damage to the remaining glass film. Control of acid concentration and temperature in the electrolytic bath allows a greater increase in productivity. A further feature of the process is the use of permeability measurements to optimize the depth of the etched regions. The improved core loss produced by the process will survive a stress relief anneal.

Abstract: A front derailleur for use in a bicycle. The front derailleur provides a plurality of speeds through selective engagement of a driving chain (60) with any one of at least three sprockets (51, 52, 53) by applying a control force to a portion of a link mechanism urged by an urging member thereby moving a chain guide (30) connected with the link mechanism against the urging force of the urging member. The link mechanism (20) is operable to move the chain guide while varying its posture so as to provide an increased pivot amount between the sprocket pair adjacent the urging side whereas to provide a reduced pivot amount between the sprocket pair distant from the urging side, in comparison with the conventional mechanism of this type. This novel construction permits sufficient urging force at the middle sprocket (53) position in accordance with increase in the deformation amount of the urging member, thereby to provide a reliable change speed operation by the sufficient urging force.
