Title: Deflection compensating roll
IPC: B41F13/08
Filed: 1976-09-30
Abstract: A deflection compensating roll is disclosed which comprises a support beam, a roll shell rotatably mounted about and defining with said beam an intermediate space therebetween and at least one hydrostatic support element engaged between the beam and the shell for exerting a force against the interior of the shell. The surface of the support element facing the interior of the shell is provided with a plurality of recesses which are supplied with fluid so that a hydrostatic fluid cushion is formed between the face of the support element and the interior of the roll shell. The beam has a longitudinally extending chamber and means for sealing a first region of the chamber which communicates with the fluid receiving recesses from a second region of the chamber which communicates with the intermediate space between the beam and the shell. The first and second regions of the chamber respectively define a conduit for supplying fluid to the support element and a conduit for discharging fluid flowing into the intermediate space from the recesses. The sealing means may include a tubular member disposed in the chamber with the end portions thereof being in fluid-tight engagement with the wall of the chamber. In this arrangement, the annular space between the outer surface of the tubular member and the wall of the chamber communicates with the intermediate space between the beam and the shell and serves as the conduit for discharge of the fluid, while the interior of the tube communicates with the recesses in the support element and serves as the conduit for supplying fluid thereto. A device such as a scoop ring disposed in the intermediate space may be provided for feeding fluid from the intermediate space to the annular space between the tubular member and the wall of the chamber.

Patent ES-474487-A1 (ES)
Title: Electrostatic Printing and Copying
IPC: G03G7/00
Filed: 1978-10-24
Abstract: In a photocopying apparatus an electrostatic latent image is optically created on a precharged photoconductor 13 and transferred to a dielectric member 25 where it is developed with toner particles and the toner image is transferred to plain paper 35. A semiconductor substrate 15 is preferably included in the photoconductor member 11. In a printing apparatus, an electrostatic image is formed on an imaging roller by an ion generator comprising two electrodes separated by a solid dielectric, with a high frequency alternating potential used to create an air gap breakdown in a region at a junction of one of the electrodes and the solid dielectric. A direct current extraction potential applied to the junction electrode is used to extract ions from the discharge thus created. The ion generator and extractor may also be used in photocopier and other applications. The image bearing dielectric member 25 advantageously consists of impregnated anodized aluminium oxide, with high resistivity, and good hardness and smoothness to ensure essentially total transfer of the toned image to a receptor medium. This transfer may be effected with simultaneous image fixing by passing the receptor between the image roller and a backup roller under high pressure.

Title: Central condition memory for telephone exchanges.
IPC: H04Q3/545
Filed: 1979-02-06
Abstract: The invention relates to a memory, used for storing data belonging to subscriber line facilities, of a centrally controlled switching system. In the known memories of this type, the memory areas belonging to similar subscriber line facilities are in each case arranged spatially adjacently for simplifying the control sequences. This can lead to problems when switching systems are extended by additional subscriber line facilities, but also in the case where a busy or faulty subscriber line facility is identified to be idle in its associated memory area. The invention therefore proposes to allocate subscriber line facilities of different types to the individual memory areas which are located spatially adjacently, so that memory areas belonging to similar subscriber facilities are arranged distributed over the entire memory.
Patent ES-477559-A1 (ES)
Title: Method of decomposing heavy hydrocarbons
IPC: C10G69/06
Filed: 1979-02-08
Abstract: Integrated process for thermal cracking of heavy hydrocarbons to obtain olefines is claimed, in which the heavy material is given a hydrogenating pre-treatment using hydrogen produced at least partly by steam reforming of light hydrocarbons in the cracked product. A separate plant and material supply for prodn. of H2 is eliminated and the light hydrocarbon products are used economically without problems of storage and transport to distant consumers. Energy for the steam reforming process can be obtd. by burning part of the light hydrocarbons. The known pre-hydrogenation process reduces the content of polyaromatics, which cause coke and tar deposition in the cracking equipment.
