Title: Ring Interworking Between Path-Switched Ring Transmission Systems
Inventor: KREMER WILHELM
IPC: H04Q11/04
Filed: 1994-08-12
Abstract: The possibility of passing off apparent "good" higher level digital signals that may include corrupted or failed lower level digital signals because of inter-ring grooming of the lower level digital signals from one path-switched ring to another path-switched ring employing at least a first shared node and a second shared node is minimized by dual feeding communications circuits from one path-switched ring to the other via the shared nodes and by provisioning at least one inter-ring groomed communications circuit from a secondary ring node of one of the shared nodes (secondary communications circuit) of a particular ring to be supplied to a primary ring node in the other shared node of the same ring. The at least one secondary communications circuit is obtained in the primary ring node and demultiplexed so that the lower level digital signals in the at least one communications circuit can be evaluated on a one-to-one pairwise basis with corresponding lower level digital signals in the corresponding at least one communications circuit (primary communications circuit) being supplied from the inter-ring grooming apparatus associated with the primary ring node. The the "best" of the lower level signals in each are selected and are combined into a "new"  primary communications circuit which is dual fed in the primary ring node in one direction to its termination ring node and in the other direction through the secondary ring node to the termination ring node. transmission path. A selector in the secondary ring node is revertively biased to normally select the "new" primary communications circuit to be supplied to the termination ring node. However, in the case of a primary communication circuit failure because of an interconnect or other failure in the primary ring node, the selector will then select the secondary communication circuit to be supplied to the termination ring node for the primary ring node.  The provisioning of the primary ring node and the secondary ring is such that the demultiplexing to obtain the lower level digital signals, their evaluation and selection, and multiplexing only need to be done in the primary ring node and not in both.

Patent CA-2140851-A1 (CA)
Inventor: TZUKERMAN SHIMON
IPC: H04L1/00
Filed: 1994-05-24
Abstract: Digital      data (particularly     encoded television program signals) are communicated from a transmitted to a terrestrial receiver by convolutional encoding the data into a first and a second signal during different periods representing a rate 1/2 signal. During the different periods, the two signals are combined and punctured into one serial punctured bit stream for producing a forward error encoded signal having a manually or automatically selected rate e.g. rate 2/3 or 6/7. Signals being encoded into different variable rates are transmitted at mutually exclusive times at first and second power levels to the receiver via a satellite. At the variable rates, parallel puncture bit streams are simultaneously derived and modulate simultaneously the pair of orthogonal carriers (QPSK). The improved puncturing method is capable of handling all of the optimum punctured codes and uses a punctured clock, multiplexer, FIFO, RAM, ROM, rate control source. The punctured clock is used to derive a pair of wavetrains the I and Q channels sequential bits and dummy bits inserted into the serial signal. The receiver responds to the QPSK carrier and derives first a serial signal having one sequential bit stream of alternating both I and Q sequential bits. Further they are sequentially as signals I and Q at the same time slots.

Title: Supporting insulator
Inventor: SCHULZ DANIEL
IPC: H02G5/06
Filed: 1995-02-20
Abstract: The supporting insulator (1)  has an insulator body (5) which is in the form of a disk and is made of cured  casting  resin,  and  has  at  least  one  cast-in fitting (2) to which high voltage is applied and which is cast in the insulator body (5)  and passes through it. The cast-in fitting  (2)  has a cylindrically con-structed outer surface (4) which the insulator body (5) encloses.        It is intended to create a supporting insulator (1) which is designed for comparatively high mechanical loads, is of simple construction, and in the case of which separation of the insulating material from the cast-in  fitting  (2)  as  a  consequence  of  mechanical loads is precluded.  This is achieved in that a lip (10), which tapers outwards and is closely connected to the outer surface (4)  of the cast-in fitting (2), is integrally formed on the insulator body (5), which lip (10)  mechanically decouples this  edge  zone  from the actual insulator body (5).

Title: Methods for producing high purity magnesium alloys
Inventor: GREEN WILLIAM G
IPC: C22C23/00
Filed: 1993-06-30
Abstract: A method for producing a high purity magnesium alloy is disclosed in which the alloying components are introduced in the molten state into molten magnesium. In accordance with the process of the invention, a predetermined amount of primary magnesium is heated and melted in a crucible. Predetermined amounts of desired alloying metals are selected and heated to their melting temperature in a separate crucible. The molten alloying metals are then introduced into the molten magnesium to sub-stantially instantaneously alloy with the molten magnesium in a reaction raising the temperature of the melt. Elemental manga-nese when first alloyed with other alloying metals prior to its addition to the molten magnesium is found to consistently be more effective in reducing the iron impurity level of the melt to a level below 50 ppm. The introduction of a molten alloy of manganese and one or more rare earth metals into the molten magnesium, reduces a settling out of the rare earth metal from the melt and increases the alloying efficiency for the rare earth metal to greater than 80 %. The efficiency of the process of the invention is sub-stantially increased, the consumption of time and energy is decreased, and the production of magnesium chloride slag and gase-ous HCl is avoided.
