Abstract: Anhydrous or substantially anhydrous formic acid is obtained by hydrolysis of methyl formate, in a process wherein (a) methyl formate is hydrolyzed, (b) the methanol and excess methyl formate are distilled from the hydrolysis mixture obtained, (c) the bottom product of distillation (b), consisting of formic acid and water, is extracted, in a liquid-liquid extraction, with an extractant which in the main takes up the formic acid, (d) the resulting extract phase, consisting of formic acid, the extractant and a part of the water, is subjected to distillation, (e) the top product obtained from this distillation and consisting of all or part of the water introduced into the distillation, and part of the formic acid, is recycled, as vapor, into the lower part of the distillation column of stage (b), (f) the bottom product of distillation stage (d), consisting of the extractant, with or without part of the water, and the greater part of the formic acid, is separated by distillation into anhydrous or substantially anhydrous formic acid and the extractant, and (g) the extractant leaving stage (f) is recycled to the process.

Abstract: The submission makes use of the fact that where an adaptive equaliser (APS) is incorporated in a modem, some sort of training sequence is employed prior to the transmission of the data message. This training sequence usually incorporates a block of pseudo-random data (DIS) transmitted at the basic symbol rate to provide the equaliser (APS) with a relatively less distorted signal to operate on. During the training period both threshold-derived timing (TCTRL) and Nyquist-derived timing (NTRL) are produced. The Nyquist-derived timing (NTRL) is then phase-shifted (APS) to correspond to the threshold derived timing (TCTRL) which is valid during the training period. The phase shift (APS) is then fixed so that, when multi-level coding is introduced valid timing can still be obtained from the Nyquist-derived timing signal (NTRL). In addition in the event of transmission interruptions the invention allows timing recovery without the need for a new training cycle.

Abstract: A method and apparatus are provided for forming a strap loop and securing it about an article (P). The strap free end is pressed against a guide surface (224) and moved in a path to form a primary strap loop (LP) while permitting the primary strap loop (LP) to twist off of the guide surface (224). With the free end of the strap (S) held against further movement, the trailing portion of the strap (S) is fed to expand the loop to a predetermined larger size. The article (P) is inserted in the loop (LF) and the trailing portion of the strap (S) is withdrawn to tighten the loop (LF) about the package (P). The trailing portion of the strap (S) is severed from the tightened strap loop (LF) and the overlapping portions of the strap (S) are then sealed by a friction-fusion weld.

Abstract: The method of feeding an insoluble organic solid material in the form of an organic resin or biological matter containing contaminating material such as radioactive waste from a nuclear facility or from treatment of animal or plant tissue in a laboratory or medical facility into a vessel containing water and to which ultraviolet light and ozone, preferably by sparging, are applied while the water is being agitated to distribute the ozone. The ozone oxidizes the organic resin or biological material, which disintegrates on oxidation substantially into water and carbon dioxide, leaving substantially no resin or biological material after treatment by the ultraviolet light and ozone for a prescribed period of time, and leaving the contaminant material as a precipitate or in solution in the remaining water or as an escaping gas, in any of which forms it can be readily separated from the water for disposal or further treatment.

Title: Universal blending silo and method
Inventor: PESCHL I
IPC: B01F25/90
Filed: 1980-11-27
Abstract: The present invention is a universal blending method for blending the material contents of a silo having a predetermined interior cross-sectional area by layer blending or across vertical columns, column blending, or a combination of layer and column blending. The presently preferred method of the present invention employs either vertical displacement of a partial vertical column of the silo content to provide a representative mixture in every horizontal cross-section in order to reduce the number of necessary recycles to a minimum or substantially simultaneous multilevel displacement, with subsequent uniform discharge over the whole horizontal cross-section of the silo to remix material that may have been segregated during the filling or recycling. In either event, the presently preferred universal blending system includes a blending bottom whose construction gives the opportunity to make a choice of (1) discharge over only a partial area of the outlet area; (2) uniform discharge over the whole outlet area; or (3) predictable discharge velocity distribution over the outlet area.

Title: Process for the preparation of liposomal medicaments
Inventor: WEDER HANS GEORG
IPC: A61K9/50
Filed: 1981-12-01
Abstract: Associates of at least one amphiphilic bilayer-forming substance and a solubilizing agent are formed in an aqueous phase. The bilayer-forming substance itself can be a pharmaceutical substance, or pharmaceutical substances and/or pharmaceutical auxiliaries may be added. The equilibrium conditions for the molar ratio of bilayer-forming substance to solubilizing agent in the associates are then changed in the aqueous phase containing the associates, in order to remove solubilizing agent from the associates, so that the associates combine to form liposomes. In particular, the solubilizing agent concentration in the aqueous phase is reduced, for example by dilution with additional aqueous phase. The change is effected at a rate which is sufficiently high for formation of liposomes having a predefined number of double layers. Furthermore, the rate of change in the aqueous phase is kept virtually constant with respect to location and time. The liposomes thereby achieve a predefined, virtually homogeneous size.

Title: Rotary kiln with a polygonal lining
Inventor: MOSCI RICARDO
IPC: F27B7/14
Filed: 1992-12-23
Abstract: A rotary kiln having a polygonal lining is disclosed for pyro-processing cement, lime, other minerals, as well as other materials. Specifically, utilizing a polygonal lining of a refractory or ceramic material having between 3 and 12 sides improves the heat efficiency or heat transfer between high-temperature gases and a burden of material to be processed by the kiln. Such an efficient utilization of the gas heat is due to various factors which cause a larger amount of the burden to be more quickly exposed to the high temperature gases. These various factors include increased tumbling, increased residence time, decreased degree of filling, and increased surface exposure.
