Abstract: PROCESS AND APPARATUS FOR RECOVERY AND REUSE OF AMMONIA IN A LIQUID AMMONIA FABRIC TREATING SYSTEM Abstract of the Disclosure The disclosure is directed to a system for the recovery of spent ammonia, in connection with the processing of fabrics and the like with liquid ammonia, and concerns particularly the elimination from the recovered ammonia of undesired water.        Economic processing of fabrics by liquid ammonia requires recovery and reuse of substantial quantities of ammonia.  In the course of processing, the ammonia unavoidably becomes contaminated with water.  Separation of water from ammonia on a laboratory level or, in any kind of batch processing is a theoretically simple matter and can be coped with by conventional differential evapo-ration techniques, or otherwise.  However, in a continuously operating processing line where large quantities of anhydrous liquid ammonia are being used as the treating medium, water accumulates rapidly, not only from the fabric being processed, but also from a certain inevitable amount of air leakage in the system,  Because so much of any given increment of the treating medium must be recycled, as compared to that actually "used up" in the treating process, water accumulates rapidly in the system and must be removed on a continuous basis.  The specification discloses a unique and highly efficient procedure for removal of water by effecting condensation of water and ammonia vapors, con-stituting the process effluent, by feeding the effluent to a de-superheating vessel, where it is brought into direct contact with a body of low temperature liquid ammonia.  This is done in con-junction with a preliminary low temperature condensation of the effluent in a non-contact heat exchange stage.  The condensed body of liquid ammonia in the desuperheater vessel, including residual condensed water from the process effluent combined with re-lique-fied ammonia, forms the feed supply of liquid ammonia solution to the process.  The condensed water, which in the new process constitutes a portion of the feed supply, is applied to the fabric being treated, along with the liquid ammonia.  Typically, some of the water is carried away with the processed fabric as a con-stituent of its moisture content.  The remainder, which is driven off as steam in the process, is recycled.     - 1a -

Abstract: ABSTRACT OF THE DISCLOSURE              The rate of solubility of a freeze-dried solid composition containing therapeutic amounts of anti-hemophilic factor (AHF) is greatly increased by carrying out the solubilization in the presence of at least a critical threshold amount of a water soluble carbohydrate.  The carbohydrate is incorporated into the AHF composition in sufficient quantity to provide at least 2 weight units of carbohydrate (expressed in grams) per 100 volume units of AHF solution (expressed in milliliters).   This enhanced rate of solubility permits rapid treatment of hemophilic patients.

Title: Housing assembly for an electromagnetic relay
Inventor: SCHEDELE HELMUT
IPC: H01H50/14

Granted: 1981-06-09
Abstract: ABSTRACT OF THE DISCLOSURE Disclosed is an electrical component including a two-part housing formed by two cup-shaped parts which are fitted one into the other to form a box with the edge of the open end of the inner part adjacent to the inner wall of the base of the outer part, and the interspace between said edge and said base being filled with a sealing material.  The construction in accordance with the invention ensures that large sealing surfaces are formed between the two parts of the housing, whilst the sealing material additionally introduced causes the edge of the inner housing part to be firmly secured to the base of the outer housing part.  Since this sealing material is in contact with the peripheral area of the base of the outer housing part, and is thus unable to escape, an excellent sealing with a low leakage rate is achieved.   Terminal pins can be moulded into one part of the housing, so that no open holes exist which would have to be resealed by means of subsequent additional measures. However, since such moulding-in of the terminals is not possible in all cases, and necessitates the use of a relatively expensive injection mould, the electrical terminal pins can advantageously be inserted between the side walls of the two parts which engage one another.  Since the end face of the inner housing part is fully surrounded by the sealing composition, terminal pins which have been inserted in this way, and arranged in the shape of syphon tubes around the end face are also fixed in position and sealed.

Abstract: ABSTRACT            A continuous gas purification process for selec-tively removing acid gases such as CO2, H2S, and SO2, other sulfur-containing molecules such as COS, and other relatively high boiling point impurities from a gas mixture stream con-taining lower boiling point components, such as H2, N2, CO, CH4, C2H4, C2H2, and the like, comprises:  Providing the gas mixture to be treated as a dehydrated stream at an initial pressure above atmospheric and at a temperature which is sub-stantially the dew point temperature of carbon dioxide in the gas stream; contacting the gas stream at such pressure and temperature with a liquid carbon dioxide refrigerant-absorbent to absorb such impurities other than CO2, and separating these impurities together with still liquid carbon dioxide absorbent from a first residual gas stream, separating a portion of the carbon dioxide component of said first residual gas stream at such pressure, preferably by condensation while further cooling the pressurized stream by indirect heat exchange, leaving a second residual gas stream; contacting said second residual gas stream at such pressure with a second refrigerant-absorbent maintained below the triple point temperature of carbon dioxide for absorbing additional carbon dioxide and leaving a third residual gas stream; and preferably, performing a final separa-tion of additional carbon dioxide from said third residual gas stream by absorption into a liquid absorbent maintained below said triple point temperature, which liquid absorbent may be a liquid phase of the second refrigerant-absorbent.          The second refrigerant-absorbent preferably comprises particu-late solid carbon dioxide suspended in an organic liquid vehicle as a slurry in which the solid phase is a mixture of carbon dioxide and organic liquid and melts to provide in situ refrigeration for condensing carbon dioxide from the second residual gas stream.  The finally purified gas stream is heat exchanged to recover its refrigeration potential and is dis-charged at substantially ambient temperature and at substan-tially said initial pressure.  Some of the liquid carbon dioxide refrigerant-absorbent is separated from sulfur-containing impurities absorbed thereby to concentrate the latter for pro-cessing in a Claus plant to recover elemental sulfur.  The absorbents used in the process are regenerated therein.          Additional carbon dioxide is recovered with a purity acceptable for discharge to the atmosphere or recovery as a by-product.          In various parts of the process, pressure energy and refriger-ation potential are recovered and used to minimize the net energy input to the process.
