Abstract: Abstract A controlled sliding valve comprises a valve housing with cylindric bore, in which a slide controlling a hydraulic flow reciprocates by an adjusting force. The sealing surfaces between the slide and bore form a sealing gap converging in the flow direction, and the size of the flow is controlled between a throttling edge and longitudinal control grooves (7,8;44,45) in the slide with variable cross-sectional area in the direction of movement of the slide. A centering spring retains the slide in closing position. In order to obt-ain low adjusting forces, to control the volume so as to be substantially constant and independent of the pressure drop over the valve, and to maintain low leakage past the slide, the valve housing includes a central chamber (6) provided with a port (3), and on both sides of said central chamber two control chamb-ers (9,10) with ports and each with a sealing gap (11 and, respectively, 12) spaced from each other.          Either of the central chamber (6) and two control chambers (9,10) communicates in all adjustment posit-ions with the control grooves (7.8), which can be caused to open to only one of the sealing gaps (11 or 12) at a time. The centering spring (13) acts centering for the slide from the positions of movem-ent where there is flow connection between the central chamber (6) and either of the two control chambers (9,10), and the flow direction is in the converging direction of the sealing gaps (18,19) whereby, thus, the hydraulic flow can pass between the central chamber (6) and one of the two control chambers (9, 10) at a time in the direction determined by the seal-ing gaps having to converge in the flow direction.     Fig. 1 to be published.

Abstract: STERILIZED STORAGE CONTAINER                        Abstract A container lid (12) is held open by a support plate (18) carrying a chamber (20) which expands at a predetermined point in a sterilizing cycle to react against the lid, moving the plate outwardly to permit the lid to drop onto the container base.  A resilient gasket (16) prevents fluid flow into the container after the lid is fallen, but permits fluid flow outwardly past the gasket when interior pressure  exceeds exterior pressure.  When the container is to be opened, a relief valve (60) relieves the vacuum within the container and filters air entering the container at that time.

Abstract: RINGING SIGNAL GENERATOR EMPLOYING DELTA MODULATION POWER AMPLIFICATION TECHNIQUES            Abstract A ringing signal generator is disclosed in which a low-level reference ringing signal, generated by a reference waveform generator is amplified by a delta-modulation power amplifier.  The low-level reference signal is digitally encoded using delta-modulation techniques to generate a high-level digital signal.  The high-level digital signal is filtered to remove the high-frequency components therefrom and to decode the digital signal to form the high-level ringing signal that has the same shape and frequency as the reference signal.  The delta-modulation power amplifier generates the ringing signal by comparing the reference ringing signai (Ei) with an analog feedback signal (Ef) reconstructed from the high-level digital signal.  The resultant binary error signal (E?) , representing the polarity of the difference between the reference and the feedback signals, is applied to a logic circuit which samples the error signal at a clock rate substantially higher than the frequency of the ringing signal, and generates two binary control signals (+SW, -SW) based upon the error signal at multiple clock instants. These control signals open and close the switching elements in a bridge switch to generate the high-level digital signal.

Abstract: Abstract of the Disclosure A diagnostic system for testing the video output and secondary storage facilities of a computer system.  The refresh memory of the video subsystem is loaded with the codes of a character string including the complete set of display characters and the code for a character that is not displayable.  A character generator responds to this non-display character with the cyclic redundancy check (CRC) code for the bits emitted by the generator in response to the string of display characters used in the diagnostic routine. A slowed-down replica of video output from the character generator is fed as a stream of bits to a slow speed serial communications port and then to the processor. The processor generates the CRC code in response to the stream of bits from the character generator and it compares this generated code with the CRC code received from the character generator. Similarly, for testing the secondary storage subsystem, certain predetermined data is stored in a portion of a primary memory unit. This data, simulating an MFM-encoded recording of known information, is transmitted by the central processor to the control unit for the secondary storage system, and is looped back through the controller for data separation and decoding and is then returned to the central processor.  The returned signal is compared with the unencoded form of the data provided to the controller.

Abstract: SIMULTANEOUS DIGITIZING APPARATUS FOR AN ACOUSTIC TOOL            Abstract of the Disclosure For use in an acoustic logging tool, an apparatus which digitizes simultaneously obtained acoustic signals is set forth in the preferred and illustrated embodiment.  The device cooperates with N acoustic receivers in a sonde.          After an acoustic pulse is transmitted, data is observed at all N acoustic receivers.   This apparatus comprises a multiplexer which is connected to the several receivers.          The several input signals are multiplexed, thereafter input to a digital data converter forming a procession of output digital words,and the words are stored in a selected order in a digital data buffer.   They are delivered to the surface through a telemetry transmitter at a slower rate than the rate at which the data is created.  In addition, a transmitter monitor is included.  This provides a signal alternately digitized for a specified interval to enable coordination of the data reduction from the acoustic receivers in contrast with the timing of the transmitted acoustic pulse.

Abstract: A PROCESS FOR DEVOLATILIZING NATURAL GAS LIQUIDS                      ABSTRACT    A natural gas liquid which has been cryogenically extracted from a natural gas feed is devolatilized by removing a portion of the ethane from the liquid.  The natural gas feed stream is initially split into two streams, the smaller part of the stream being fed to the bottom of a demethanizing absorber at a low temperature and the larger part of the stream being fed to the top of the absorber at a substantially lower cryogenic temperature.  A methane-rich gas product is recovered from the top of the absorber while the methane-lean liquid in the bottom of the absorber is fed to a non-cryogenic deethanizer.  A portion of the vola-tiles in the methane-lean liquid are removed in the deethanizer and re-cycled back to the absorber leaving a devolatilized natural gas liquid product.

Abstract: ABSTRACT OF THE DISCLOSURE            A biologically active substance with standardized effect is proposed, containing in a physiological medium at least one histone, particularly an H2 histone or an active region of this histone.  The use of histones and/or histone segments for producing such a preparation is also proposed.  The histones can be obtained from a biological source material, e.g. calf thymus.  Since H2a and H2b histones from cows and humans are identical, histones obtained for the preparation according to the invention can also be used in human medicine applications. Preparations according to the invention may contain only one evolutionally variable segment of at least one histone, in particular an H2a or H2b histone.  Such segments can be pro-duced relatively easily by synthetic and/or genetic engineering methods.  The invention is based substantially on the finding that the active area of an immune stimulating or endocrino-logically active histone lies within the evolutionally variable histone segment.  The preparation according to the invention can also be used in immune therapy.  One of its properties is that it can be used as a corticotropine (ACTH), thyroid gland and gonad antagonist and a growth hormone (GH) synergist.  It is also applicable in immunological weaknesses (e.g. in malnutrition) and in the immune deficiencies following thymec-tomy or massive radiation of the thymus for the prevention of radiation-induced leukemia and in cancer treatment and is suitable for diagnostic procedures.
