Title: Protection for mechanical operations in glove-boxes contg. radioactive - comprises cap fixed temporarily on inner wall eliminating need for total decontamination
IPC: G21F7/047
Filed: 1978-08-11
Abstract: A protective device, for carrying out safety work on the walls or receivers contg. substances which are treated while being kept remote from the surroundings, comprises a cap which can be fixed on the inner surface of the receiver at the place where the work is to be carried out. The cap has a suitable filter facing the internal space of the receiver. The edge of the cap has a flexible ring which makes a seal when the cap is held against the wall, e.g. by suction or magnetically. Typical examples of receivers are glove boxes in which-radio-active substances are handled. They are kept constantly at a press, slightly below atmospheric so that no radio-activity can pass to the exterior, and are equipped with filters. Such boxes can also be used for handling pharmaceutical products, bacterial cultures, toxic substances etc. However, it may be necessary to carry out work to install cables or pipes. The invention eliminates the problems associated with such work, e.g. the need for prolonged cleaning under conditions requiring personal protection. Only the part where the cap is fitted needs to be decontaminated. The cap ensures automatic collection of residues from the work carried out. Pieces detached from tools can easily be recovered without damage.

Title: Process for the dyeing in a gel state of fibrous articles spun from acrylonitrile polymer solutions in organic solvents.
IPC: D06P3/76
Filed: 1981-07-10
Abstract: A wet-spun never-dried fibre material in the gel form comprising an acid-modified homopolymer or copolymer of acrylonitrile (PAC fibre) is advantageously dyeable with colour-fast results using soluble dyes which have in their molecule a plurality of groups, specifically more than one quaternary grouping and/or an uncharged strongly basic grouping, which act basic toward the acid groups of the fibre substance. The chromophore of this colorant can come from the category of the monoazo or disazo dyes, the methine, azamethine or diazamethine dyes or the naphthalactam dyes. The dyeing of the never-dried fibre is advantageously carried out continuously or batchwise from a solvent-containing dyebath which in addition to water contains portions of an organic solvent, specifically the solvent used for spinning the polymer the drawing of the fibres can take place before, during or immediately after the dyeing process. Owing to their special nature, the fast-dyeing dyes of the aforementioned type give optimum rates of fixation in the dyeing of PAC gel fibre, and do not cause any marked staining of machine parts and working baths, for example drawing or aftertreatment baths, due to leached dye in the subsequent production stages. Investigations of the fibre penetration, the rate of fixation and the resulting fastness properties, such as the wet fastness, did not reveal any disadvantages compared with conventional dyes.

Title: Process for the treatment of the bottom product of extractive-distillation processes for obtaining pure hydrocarbons.
IPC: C07C7/08
Filed: 1981-07-24
Abstract: A method for working up residues of an extractive distilling process for obtaining pure hydrocarbons. The residue from an extractive distilling column is fed to the about middle part of a distilling column. The hydrocarbons are distilled and removed at the head of the distilling column and the solvent is removed at the bottom of the distilling column. A sidestream is removed from the distilling column at a position above the feed plate for the residue from the extractive distilling column via a so-called reflux evaporator plate having an elevated level of liquid. The sidestream is heated by indirect heat exchange with the solvent flowing from the distilling column. The heated-up sidestream is fed back into the distilling column at a level at or above the reflux evaporator plate. The concentration of the solvent at the reflux evaporator plate is controlled by the amount of reflux at the head of the distilling column. The heating of the side stream reduces the heat requirement of the bottom boiler of the distilling column by about 35 percent.

Patent ES-8306291-A1 (ES)
Title: Solid-state load protection system having an improved inverse time delay circuit
IPC: H02H3/093
Filed: 1982-04-26
Abstract: A solid state load protection system having an inverse time delay circuit. A current sensing function is utilized so as to produce an output current which is proportional to the current in an electrical circuit. Attached to the current sensing function is a load resistor which converts the current produced by the current sensing function to a voltage which is proportional to the current utilized by the load. Attached to the load resistor is an inverse time delay circuit which serves as an overcurrent and timing function. The overcurrent and timing function monitors the level of voltage from the load resistor initiating a time-out sequence when the voltage across the load resistor, which is proportional to the current utilized by the load, exceeds a predetermined level for a predetermined period of time. The overcurrent and timing function utilizes two diode paths for prohibiting the charging or discharging of a capacitor during a normal or overcurrent condition, respectively. Encircling the connections to the capacitor is a guardband for minimizing impedances from associated circuitry which affect the timing of the inverse timing circuit. During an overcurrent condition, the capacitor charges up to a specific value initiating a trip signal which is sent to an output function. The output function upon receiving a trip signal causes a light-emitting diode to conduct and also deenergizes a contactor through which a current source is connected to a load.
