Abstract: ABSTRACT     For the purpose of recovering and transporting in a non-environ-mentally polluting economical manner the solid substance of a peat bath suspension or of a similar aqueous, homogeneous suspension having a low 2 to 5% solid content principally of organic fibres, the present invention provides a method for draining the said suspension by passing it continuously through a static filtration stage having curved or inclined screens where at least a part of the present free water is separated from the suspension to a resulting water content of 90 to 94% therein; a first mechanical double belt screen pressure stage where the remainder of the free water and some of the combined water which is bound and latent in the fibres is separated from the suspension to a result-ing water content of less than 90% merely by the pressure arising from the tension of the belt screens; and a second double belt screen pressure stage where the belt screens pass between pressure rollers and where more of the combined water of the fibres is separated from the material to a water content of 80.%, the filtrate arising in the first stage being first purified and then fed to a sewage system with a solid content of at the most 1 gram per litre of water.  The fraction still containing fines, separated during purification, is returned to the process for draining.

Abstract: XEROGRAPHIC ELECTRONIC PRINTER                    Abstract of the Invention This invention relates to a system for non-impact printers such as those that use light emitting diodes (LEDs) to produce an image on a photoconductor.  In such devices, a discontinuity is generally created in a line of printed characters because of the movement of the imaging surface relative to the LED array.  The system of this invention eliminates such discontinuity through adjustment in the enabling sequence of the LEDS of the array.

Abstract: Abstract Automatically adjustable equalizing network.     An automatically adjustable equalizing network comprises a number of regulating networks (I,...IV) connected in cascade. The regulating networks are controlled by the same control voltage which is derived from a peak detector (6). Each regulating network (I,...IV) is connected to a different reference voltage derived from a potential divider (11-17) arranged between supply terminals (9,18). The arrangement is such that each regulating network (I,...IV) becomes operative only after the preceding network has reached its extreme regulating position (Fig. 1).

Abstract: Abstract of the Disclosure An addressable CATV converter for connection with a remote headend in a cable distribution system includes a pro-grammable read-only memory in which a unique identification code for the converter is stored, and a random-access memory (RAM) which can be programmed with the unique assigned conver-ter address after the converter is installed at the subscriber location.  The converter includes a data receiver which, when the converter is connected to the cable receives from the headend a unique preassigned address code corresponding to the unique identification code stored in the PROM.  When the iden-tification code stored in the converter PROM is matched at the converter with the received identification code, the unique preassigned address code is stored into the converter RAM, thereby to enable the headend  to thereafter efficiently com-municate with the converter.  The invention provides an addres-sable converter in which a unique address can be loaded or stored from a remote headend controller.  The converter need not be mechanically handled or mechanically modified after its manufacture.

Abstract: ABSTRACT OF THE DISCLOSURE      Blind fastener of the type having a tubular outer member with a head at one end and a conical portion at the other end, the conical portion having its apex with-in the outer member.  The conical portion is expanded radially to form a second head on the fastener for se-curing it in place.  The member selected for expanding the conical portion comprises a spring pin.  In some em-bodiments novel apex contacting means are interposed be-tween the spring pin and the apex of the conical por-tion.  The apex contacting means is either formed in-tegrally with one end of the spring pin or as a separate piece disposed between the spring pin and the apex of the conical portion.  One important advantage of using a spring pin as the setting means is that its resilience retains it within the outer member despite vibrations, temperature changes, or other conditions which might tend to dislodge the setting means.  Other advantages are lighter weight and greater strength at no more cost than previous solid setting pins.

Abstract: ABSTRACT          An encoder converts an analog input signal to a digital signal.  The encoder comprises means for generating a control signal with a predetermined bandwidth from the input analog signal.  The control signal indicates the desired optimum step-size to be applied in the encoder.  The encoder further comprises a converter for converting the analog input signal to a digital signal.  The converter is responsive to the control signal representing step-size so that the digital signal will be generated in accordance with the step-size information.  Since the generation of a limited bandwidth control signal requires time, the encoder also includes means for introducing time delay to the analog input signal, so that the delayed input signal reaches the converter when the control signal is available for digital encoding.  A decoder generates an analog output signal from a digital signal received from an encoder through a transmission medium.  The digital signal received includes a digital representation of an analog input signal to the encoder and step-size information which was used to digitally encode the analog signal in the encoder.  The decoder comprises a converter responsive to a second control signal of limited bandwidth derived from the step-size information for generating from the digital representation an analog output signal.  The analog output signal so generated is similar to the input analog signal.

Abstract: ABSTRACT OF THE DISCLOSURE          An eaves troughing assembly includes elongated eaves troughing members of resilient material with generally U-shaped section having a rear portion, base portion and front portion, the front portion of each eaves troughing member having a longitudinally extending recess in a front face at least adjacent an end of the member.  Elongated connectors of re-silient material with generally U-shaped section have a rear connector portion having an inwardly extending upper free end poriton forming a recess between the free end portion and an adjacent part of the rear connector to receive an upper end of the rear portion of an eaves troughing member.  The front portion of each connector member has a longitudinally extend-ing projection in a rear face shaped for snapping engagement in the recess of an eaves troughing member.  A connector member can be assembled with adjacent eaves troughing members, when they are longitudinally aligned with each other with ends substantially abutting, by initially causing the upper ends of the rear portions of the eaves troughing members to be received within the recess of the connector, with the remainder of the connector being below the eaves troughing members.  The con-nector is then moved angularly upwardly relatively to the eaves troughing member to cause longitudinal projection of the connector to move into the recesses in the front faces of the front portions of the eaves troughing members and snap into engagement therewith with the rear portion, base portion and front portion of the connector engaging the corresponding portions of the eaves troughing members.
