Patent BG-49312-A1 (BG)
Title: Method for dehydrating of acethropic mixture isopropyl alcohol- water
Inventor: TASEV ZHIVKO A
IPC: B01D63/04
Filed: 1989-11-01
Abstract: The method is applied in chemical industry. It has a simplified scheme, reduced expenditure of heat and ensures the production of an absolute isopropylene alcohol that contains no impurities. The method: water from an aceotropic mixture is evaporated via a selective membrane in the type of hollow fibres from cellulose hydrate (regenerated cellulose) through building vacuum in the inside of the fibres. The liquid mixture - to be subject to dehydration - contacts with the membrane from the external surface of the fibres and the water from the mixture is selectively permeated by the membrane, difunds through it and evaporates after passing through the other side of the membrane as a result of the created vacuum in the inside space of the hollow fibres. In this way, the passing liquid mixture is continuously dehydrated. It operates at a temperature lower than that of boiling temperature for the mixture.

Filed: 1990-12-06
Abstract: L'invention se rapporte à un coupleur servant à relier par couplage des composants électroniques haute vitesse pour l'échange bidirectionel de signaux entre eux et conçu en particulier pour l'acheminement de tels signaux en direction de diodes laser, excitées par deux signaux haute fréquence ou par des impulsions trés courtes, et en provenance de photodiodes haute vitesse. Le coupleur se compose d'un dispositif obtenu par l'assemblage d'au moins deux structures à lignes de transmission planes différentes, le conducteur central porteur de signaux (22, 31) étant partagé par toutes les structures ainsi assemblées, tandis que les plans horizontaux (26, 27, 29, 32, 33, 34, 36) maintiennent la position caractéristique de chacune des structures ainsi assemblées par rapport au conducteur. La variation d'impédance caractéristique, qui passe de l'impédance de ligne habituelle de 50 ohms à une impédance de diode de 5 ohms, est obtenue progressivement le long du dispositif par l'intermédiaire de l'effet cumulatif des variations d'impédance individuelles de chaque structure à ligne de transmission formant le coupleur, ces variations résultant du changement graduel des dimensions de la section transversale du coupleur dans le sens de la longueur.

Patent CA-2008753-A1 (CA)
Inventor: WHIPPLE DAVID L
IPC: G06F13/37
Filed: 1990-01-29
Abstract: Apparatus for determining in a data processing system (102) priority of access to a bus to (l04) by nodes (603) in a group of nodes (603) attached to the bus (104).  For purposes of determining priority, the apparatus arranges the nodes (603) in a circular configuration along a priority bus (106) and selects one of the nodes (603) as the "anchor node".  The anchor node has the highest priority and the priorities of the other nodes (603) are determined by their positions in the priority circle relative to the anchor node.  Each node (603) includes a presettable counter (720) for indicating a number of times that a node (603) may access the bus (104) before the highest priority is rotated to another node (603).  After a device represented by one of the nodes (603) accesses the bus (104) for a predetermined number of accesses the current anchor node ceases being the anchor node and the next node in the circle becomes the new anchor node.  The priorities of the nodes change to reflect the new location of the anchor node.

Title: Gas sealing valve and valve equipped plastic processing installation
Inventor: KLOTZ BERND
IPC: B29C49/06
Filed: 1990-03-28
Abstract: With a gas closure valve (18) for plastic processing apparatuses, in order to avoid streaking in the moulding even at very high gas pressures, and to ensure high flexibility in production without change-times, it is proposed for the valve needle (40) to be controlled by a control plunger (60), which for its part is controlled by means of a working gas volume. When material is fed to the mould (16), the valve needle (40) closes material-tightly, whereas when gas is returned the valve needle (40) remains open until the gas bubble formed in the cavity of the mould (16) has been completely discharged.

Abstract: A composition for separating out volatile pollutants from gases and exhaust gases comprising calcium hydroxide and water-soluble salts of sulfur-containing compounds, e.g., mercaptans, sulfides, polysulfides, polythionates and thiosulfates or elementary sulfur which are used in combination with surface-active substances. Possible ways to produce the composition include adding the sulfur-containing compounds to quicklime during slaking, to the slaking water or, subsequent to slaking, to calcium hydroxide. The compositions are used for removing the volatile heavy metals, particularly mercury, arsenic, cadmium, thallium, antimony and lead, at temperatures ranging from 0 ° C to 400 ° C. For this purpose, the composition is blown as powder into the exhaust gas stream, and the resultant products are separated out at fabric filters. Upon addition of surface-active substances, volatile organic pollutants are removed simultaneously with the afore-mentioned inorganic pollutants.
