Abstract: A rotary piston machine, in order to avoid losses due to compressed flows, has adjacent to a generating and/or sealing contact edge (21, 22) at least one recess (11a, 11e) and/or opening (12a, 12b) which extends beyond the contact curve (14a-14c) in at least approximately the direction of motion of the surfaces moving in relation to each other during the stroke or passage of the piston (6a'') through the shut-off driver. The spatial dimensions of the recesses and/or opening are such that the flow in it is not substantially accelerated even when the direction is changed. An opening (11g, 11g') can be closed insofar as it is located in a nonmoving ring (6b). To prevent low pressures between surfaces moving away from each other (9c, 14c) a pressure compensation space (11e) is connected to the contact line (14c) of one of the surfaces.

Abstract: Ultrafiltration is performed with two or more membrane cartridges (A,B,C) arranged in series. Feed of solution or suspension is supplied to each cartridge at a pressure which would normally exceed the maximum allowable transmembrane pressure were it not for the back pressure applied on the permeate side. The magnitude of the back pressure is adjusted so that the resultant transmembrane pressure does not exceed the maximum allowable. For an arrangement where three cartridges (A,B,C) are used, the first unit (C) has an inlet pressure of 50-120 psi and a back pressure of 25-95 psi. The second unit (B) has an inlet pressure of 40-80 psi and a back pressure of 15-55 psi. For a three cartridge arrangement, a 36.5% increase in efficiency can be obtd. together with a 53% reduction in energy costs. The ultrafiltration of electrophoretic paint and cheese whey is exemplified.

Abstract: The invention relates to a method for preparing a sui- phidic concentrate which is intended for further processing to copper and/or precious metals and which contains high percentages of arsenic and/or antimony, and possibly also bismuth in quantities likely to disturb subsequent processing stages, by partially roasting the concentrate in a fluidized bed, so as to eliminate substantially all the arsenic present and a major part of the antimony and/or bismuth. According to the invention, the concentrate and gas are supplied to a fluidized-bed reactor, and are there heated to a minimum temperature above the splitting or decomposition temperatures of the complex minerals containing arsenic and/or antimony and bismuth present in the concentrate. The oxygen potential in the reactor is regulated, so as to prevent the formation of non-volatile compounds of said impurities. The residence time of the concentrate in the reactor is controlled in a manner to ensure a given minimum elimination of the impurities. The gas and solids are withdrawn from the reactor and passed to a separating means, in which substantially impurity-free solids can be separated from the gas. The aforesaid minimum temperature and said regulated oxygen potential are maintained while the solids are in contact with said gas, and at least a part of the separated solids is returned to the reactor, for controlling the residence time, and an end product is removed from the fluidized bed and/or the separating means. The method is suitably carried out in one stage in a fluidized-bed reactor having a circulatory fluidized bed, although in certain cases the method can be carried out in two stages, in mutually separate reactors.

Abstract: Recombinant DNA technology is used to produce the transforming growth factor- alpha  (TGF- alpha ) precursor and its fragments. TGF- alpha  precursor and its fragments, including particularly mature TGF- alpha , and optionally in combination with human transforming growth factor- beta , has utility for example in the therapeutic treatment of human beings for bone diseases and to accelerate wound healing. In addition, TGF- alpha  is useful as an adjuvant for cell culture so as to reduce requirements for serum in the culture media (thereby resulting in purification advantages), and to stimulate or enhance cell growth in cell culture. Also, preparation of large quantities of the TGF- alpha  precursor and its fragments enables the preparation of reagents for the assay of the TGF- alpha precursor and its fragments in body fluids for the diagnosis of neoplastic or other diseases.

Abstract: A method and apparatus for transferring data between a disk and a CPU is disclosed comprising a pair of toggling header buffers and a pair of toggling data buffers. In operation, data is transferred between a sector on a disk and one of the data buffers under the control of one of the header buffers. While the data in the header buffer is being transferred between the data buffer and a CPU, data is transferred between an adjacent sector on the disk and the other data buffer under the control of the other header buffer. The rate of transfer of data between the data buffer and the CPU is higher than the rate of transfer of the data between the disk and the other data buffer. This provides sufficient time to check the data transferred from and to the CPU for errors and to address a new sector on the disk prior to the completion of the data transfer of the previous sector between the disk and the data buffer. By means of the method and apparatus disclosed, all sectors in a track on a disk can be transferred between a disk and a CPU within a single revolution of the disk.

Abstract: An optical fiber telecommunication device comprises an interconnecting volume and N stations connected to this volume by pairs of transmit and receive optical fibers. Each station comprises a tunable optical frequency laser coupled to the transmit fiber and a heterodyne receiver system coupled to the receive fiber. It is provided with a tunable frequency laser local oscillator. The volume is disposed in a central office comprising a clock to determine different timing periods assigned to the N stations. The carrier frequency of the laser for each station is initially adjusted to a first frequency reserved for modulating ringing signals in the respective channels. The central office comprises a processor connected to the interconnecting volume to receive the ringing signals and designate a carrier frequency for each call request. This frequency is transmitted through the interconnecting volume to the calling station and the called station on a second reserved frequency. This is in order to adjust the frequency of the laser and the frequency of the local oscillator to the designated frequency. The designated frequencies are different for all calls in progress at the same time.
