Patent GB-2125227-A (GB)
Title: Transformer insulation
Inventor: LACEY PHILIP EDWIN JAMES
IPC: H01F27/32
Filed: 1983-07-13
Abstract: A transformer comprises a laminated core 10 having a figure-of- eight configuration, the central limb of which carries a rigid insulating bobbin 12 on which are concentrically wound the primary and secondary windings 14 and 16. The concentric windings 14 and 16 are isolated from one another by a layer of insulating tape 30. The tape used is extremely extensible so that its longitudinal margins can be stretched to extend radially outwards and over the edges of the end flanges 20 of the bobbin 12. The tape insulation 30 thus extends around the outer winding 16 without breaks or interstices. The core 10, bobbin 12 and windings 14 and 16 are designed so that, in the assembled transformer, there are spaces between the outer winding and the core 10. These spaces are filled with a semi-rigid curable insulating compound 26 in order to prevent breakdown between the winding and the core 10 of the transformer which, in use, are at different potentials. Such transformers can withstand high voltages and can, therefore, be used for providing safety isolation using a standard bobbin in a wide range of sizes. <IMAGE>

Title: A reforming process having a high selectivity and activity for dehydrocyclization, isomerization and dehydroisomerization
Inventor: FIELD LESLIE A
IPC: C07C5/41
Filed: 1984-06-29
Abstract: A hydrocarbon conversion process is disclosed wherein a hydrocarbon feed is contacted with a reforming catalyst in the presence of a halogen at conditions which favor dehydrocyclization, isomerization, and dehydroisomerization of the hydrocarbon feed. The degree of the isomerization and dehydroisomerization is controlled by adjusting the amount of halogen present. The amount of halogen present can be controlled on stream by adjusting the addition of halogen-containing gas, or of water when halogen is present in the catalyst. The reforming catalyst comprises a large-pore zeolite having an effective pore diameter of 6 to 15 Angstroms containing at least one Group VIII metal, such as platinum, and advantageously an alkaline earth metal, such as barium, and an acidic or acidifiable inorganic binder, such as silica-alumna, zirconia-silica or alumina.

Title: Load balancing in multi-processor system
Inventor: NAGANUMA JIRO
IPC: G06F9/44
Filed: 1987-12-17
Abstract: Processors linked by a network system process a given load written in a logic programming language. According to an initial load balancing algorithm, each processor 21 independently and dynamically selects an initial load segment by use of stored information 23, 24 representative of the system status without transferring information between the processors. After the initial load balancing, a partial load segment of a first processor is shared by a second processor. In this case, the first processor generates history information representative of its working environment, but the amount of the history information is smaller than that of the whole working environment of the first processor. This history information is supplied to the second processor which uses it to reproduce the working environment of the first processor. Thereafter, the second processor processes the partial load segment. The amount of transferred information is less than that of a conventional multiprocessor system, whereby the load balancing can be performed at high speed. …<IMAGE>…
