Patent EP-0005503-A1 (EP)
Inventor: JOEL AMOS EDWARD JR
IPC: H04Q3/555
Filed: 1979-05-09
Abstract: A nodal switching network is disclosed wherein each node is connected to distant nodes by groups of links whose lengths are ordered to span distances definable by powers of a finite (preferably binary) integer. Starting at the calling node. a single idle link in a preferred coordinate direction is attempted to be seized to extend the connection as far as possible by a direct path. If a direct path link spanning the most of the distance in the preferred coordinate direction cannot be seized, a direct path link is attempted to be seized in another coordinate direction. If no link which would extend the connection most efficiently in either coordinate direction can be seized, links of less direct length in the coordinate directions are tested. If the call is still blocked, the procedure is repeated in the direction from the called node toward the calling node.

Abstract: A novel one-step process for the preparation of mandelic acid esters of the general formula <IMAGE>  in which    R represents alkyl,   X represents alkyl, aryl, hydroxyl, alkoxy, halogen, haloalkyl and/or nitro, and    n represents an integer from 0 to 3, by reaction of mandelonitriles (benzaldehyde cyanohydrins), alcohols and hydrogen chloride, in which, if desired, the nitrile nitrogen can be simultaneously obtained in the form of solid ammonium chloride. The process is characterised in that the corresponding mandelonitriles are reacted, per mol, with 3 to 20 mol of an alcohol of the formula R-OH and either with 1.8 to 3 mol of hydrogen chloride or with the addition of up to 1 mol of water containing 1.2 to 2.4 mol of hydrogen chloride at temperatures between 40 and 160 DEG C and after a reaction time of about 3 to 10 hours  a) worked up in a customary manner and the products isolated or b) in the case in which it is desired to obtain the nitrile nitrogen in the form of solid ammonium chloride, excess hydrogen chloride is neutralised with gaseous ammonia, an aromatic, optionally chlorinated hydrocarbon is added and, for working up, the excess alcohol is removed by distillation, the precipitated crystalline ammonium chloride is filtered off after cooling and the mandelic acid ester is isolated from the organic filtrate by distillation. The mandelic acid esters are used as organic intermediates, for example for the preparation of herbicidal active substances.

Abstract: A precoat composition including a particulate vitreous material and a particulate lubricant material (graphite and or boron nitride) dispersed in an organic medium comprising a solution of a polymeric binder is applied to the workpiece, and the workpiece is heated to a temperature (1000 to 1400°F) sufficient to remove (538 to 760°C) the organic medium and leave a residue of vitreous material and lubricant material on the workpiece. The workpiece is then inserted in a heated split die at 1350 to 1750°F and the die loaded to alter the shape (752°C to 960°) of the workpiece.  
The ratio of the lubricant material to the vitreous material is at least 1:1 and the particle size of the lubricant material and the vitreous material is not more than 200 mesh (U.S. Series), this being important for the surface quality of the shaped workpiece.

Abstract: A line trunk group is connected by way of a compensating memory to an input and, in fact, to those of the time slot multiples of the PCM switching network. Uniform time slots of the pulse frame boundaries within the switching network are provided. However, in the last switching stage and, in fact, in time slot multiples, displacement of a pulse frame boundaries in the lines leading back to the trunk line groups is provided. In this manner, line trunk groups acquire the frame clock rate. This influences, in respect of time slots, the transmission of sub-items of information from the line trunk groups to the switching network with regard to pulse frames of these sub-items of information, i.e. the relevant time slot of the pulse frame boundaries. Cable transit time on lines from the switching network to the line terminal group and from the line terminal group to the switching network, and delaying influences within the line trunk group which result in partially constant and partially variable delay values, are compensated, in part, by the above-mentioned displacement and, in part, by storage in the compensating memory, which can be adapted in terms of storage time, and, in fact, by increasing the delay to a full pulse frame duration or in multiple thereof. Economy of storage capacity in the compensating memory is therefore provided.
