Patent EP-0319208-A1 (EP)
Inventor: HARRISON GEORGE EDWIN
IPC: C07C29/14
Filed: 1988-11-25
Abstract: A liquid phase catalytic hydrogenation process is described in which an organic feedstock, such as an aldehyde containing from 2 to about 20 carbon atoms, is contacted with hydrogen in the presence of a solid hydrogenation catalyst under hydrogenation conditions to produce a hydrogenation product, such as the corresponding alcohol containing from 2 to about 20 carbon atoms, which process comprises passing a feed solution of the organic feedstock in an inert diluent therefor downwardly in co-current with a hydrogen-containing gas through a hydrogenation zone containing a bed of a particulate hydrogenation catalyst whose particles substantially all lie in the range of from about 0.5 mm to about 5 mm, maintaining the bed of catalyst particles under temperature and pressure conditions conducive to hydrogenation, recovering from a bottom part of the bed a liquid phase containing the hydrogenation product, controlling the rate of supply of the feed solution to the bed so as to maintain a superficial liquid velocity of the liquid down the bed in the range of from about 1.5 cm/sec to about 5 cm/sec, and controlling the rate of supply of the hydrogen-containing gas to the bed so as to maintain at the top surface of the bed of catalyst particles a flow of hydrogen-containing gas containing from 1.00 to about 1.15 times the stoichiometric quantity of hydrogen theoretically necessary to convert the organic feedstock completely to the hydrogenation product.

Abstract: The present invention provides an automatic blanket wash system that recirculates a separable mix of water and sol­
vent. The mix is selectively applied to the blankets of blanket cylinders by selectively opening spray valves associated with 
spray bars (125, 126) at the blankets. The mix circulates through the system at low pressure until just prior to the com­
mencement of spraying at which time a diverter valve (32) in a unit control (121-124) to upper and lower spray bars opens 
and permits the mixture to flow through a fluid path in the spray bars. A pressure control arrangement then causes a pres­
sure build up in the system for the spraying of the mix onto the blankets.

IPC: F16K31/10

Abstract: A valve for sealing a conduit under pressure has an armature (12) cooperating with two springs, a permanent magnet, and a solenoid coil. The force of the permanent magnet is used to cock a spring and thereby stored primarily as a spring force when the valve is in any of its two end positions. THe spring force is slightly smaller than the permanent magnetic force of the permanent magnet, and this slightly smaller spring force is effective on a valve stem through a sleeve in a direction opposite to that of the permanent magnetic force. The permanent magnetic force is, for example, stored in a Belleville spring and additionally in a helical or conical spring which provides an extra valve biasing force. In order to open the valve, the solenoid coil (9) of an electromagnet is energized to counteract the force of the permanent magnet to an extent slightly below the stored spring force. Thus, this valve is capable of having a monostable or a bistable characteristic, depending on the adjustment of the spring force with the aid of an adjustment ring engaging a threading on the valve stem.

Abstract: A solder paste for use in a reducing atmosphere is disclosed. The solder paste includes a solder powder and an alcohol binder. The reducing atmosphere serves as a flux, thereby eliminating flux residues and the problems associat­ed therewith. Solder splattering is reduced by using a polyhydric alcoholic binder which vaporizes or decomposes before the solder liquifies during heating. The use of such a solder paste in a reducing atmosphere results in no hazardous chemical by-products and, because the solder is handled in the form of a paste, is compatible with electri­cal components requiring precise dimensional tolerances.

Abstract: For modifying the parameters ( alpha i) of an adaptive recursive network (ANW), correction signals (U(n)) are needed which are in each case formed from the product of the signal of the sign function (sign(x)) of the associated gradient (dA(n)/d alpha i) of the output signals (A(n)) of the network (ANW) with respect to the network parameters ( alpha i) and from the associated difference signal (D(n)) of mutually corresponding nominal (S) and output signals (A(n)). The proportionality factor (K) preferably corresponds to the inverse value of twice the number (m) of parameters ( alpha i) to be adapted in the network (ANW). This results in an improvement of the speed of adaptation at low signal levels and a reduction in the complexity of implementation. …<IMAGE>…
