Abstract: A B S T R A C T   An adjustable hydraulic shock absorber of the dashpot type which includes an elongated outer tube and an inner tube fixed in said outer tube. A piston is movably mounted in the inner tube and has a piston rod extended outwardly of the outer tube for receiving reciprocating actuating loads. A double action, flexible, tubular diaphragm is positioned in the outer tube, with its inner end secured to the outer tube in a position sur-rounding one end of the inner tube, and with its outer end secured to the piston rod, so as to form an expandable fluid reservoir. The reservoir is connected by passageway means to the inner tube. The reservoir, passage-way means and inner tube are normally filled with fluid under pressure so as to normally move the piston to an initial load receiving position. An adjustable, combination check valve and metering valve means is mounted in the fluid passageway means for providing a controlled flow of fluid from the inner tube to the reservoir when a load is received by the piston rod to move the piston into the inner tube, and to allow a free flow of fluid back from the reservoir to the piston cylinder after the load is removed and to move the piston back to its initial position.

Abstract: 23-6-1978                      -46-                  PHN. 8888.      ABSTRACT:                A system having a transmitter and a receiver for transmitting binary data signals of a given symbol rate, and angle-modulated carrier signal of a sub-stantially constant amplitude and a continuous phase being generated in the modulation stage of the transmitter, and the transmitted modulated signal being orthogonally, coherently demodulated in the receiver.                The modulation stage of the transmitter is arranged so that the phase of the modulated signal changes in each symbol interval by an amount from the sequence -?/2, 0?/4, 0, ?/4, ?/2 (rad.), which amount is determined for the relevant symbol interval by at least two successive data symbols, and the shape of the phase within the relevant symbol interval is determined by a filtered version of at least these two successive data symbols.                These measures result in a system which, without sacrificing the remaining desired communication properties of FFSK-systems, utilizes the available fre-quency spectrum in a more efficient manner than FFSK-systems, because the modulated signal has both a narrower spectral main lobe and, for frequencies outside this spectral main lobe, considerably less power than the FFSK-signal.  Consequently this system is very well suited for efficient data transmission over radio links.

Abstract: DRIVE SYSTEM FOR CENTRIFUGAL PROCESSING APPARATUS     Richard I. Brown Joseph Kevin Duffy ABSTRACT OF THE DISCLOSURE     Centrifugal processing apparatus in which a processing chamber is rotatably mounted with respect to a stationary base.  An umbilical cable segment is fixed at one end substantially along the axis of the processing chamber at one side thereof, with the other end of the cable segment being attached substantially on the axis in rotationally locked engagement to the processing chamber.  A coaxial main drive shaft is provided and is driven at a first angular velocity.  The cable segment extends from its location in rotationally locked engage-ment to the processing chamber, through a central bore ]defined by the main drive shaft and radially outwardly therefrom.  Power is transmitted to the processing chamber via a transmission shaft which is parallelly located with respect to the main drive shaft and operative to turn in the direction opposite to the direction of the main drive shaft.  The countershaft is coupled so that when the main drive shaft is driven at the first angular velocity, the processing chamber will effectively rotate at twice the first angular velocity.  The construction of the processing system is such that the drive is substan-tially hidden and requires a relatively small number of seals.

Abstract: Abstract of the disclosure Conversion of raw coal to distillate liquid and gaseous hydrocarbon products by solvent liquefaction in the presence of molecular hydrogen employing recycle of mineral residue is commonly performed at a higher thermal efficiency than conversion of coal to pipeline gas in a gasification process employing partial oxidation and mathanation reactions.  The prior art has disclosed a combina-tion coal liquefaction-gasification process employing recycle of mineral residue in the liquefaction zone wherein all the normally solid dissolved coal produced in the liquefaction zone is passed to a gasification zone for conversion to hydrogen, where the amount of normally solid dissolved coal prepared and passed to the gasifica-tion zone is just sufficient to enable the gasification zone to produce the exact hydrogen requirement of the process.  The present invention provides an unexpected improvement in the thermal efficiency of the combination process by utilizing formulas based on feed coal characteristics to calculate an amount of normally solid dissolved coal to be prepared in the liquefaction zone and passed to the gasification zone to enable the gasification zone to generate not only all of the hydrogen required by the liquefaction zone but also to produce synthesis gas for use as fuel in the liquefaction zone.  It would have been expected that shifting some of the processing load from the ordinarily more efficient lique-faction zone to the ordinarily less efficient gasification zone would decrease process efficiency, but the present combination process unexpectedly achieves an overall efficiency increase by said shift.

Abstract: U.S. 944,633 ABSTRACT OF THE DISCLOSURE (SEE FIGURE 1) First through fourth  NPN switching transistors 1, 3, 5, 7 having bases receptive of first through fourth control signals, respectively, are connected in cascode between a first terminal 9, for receiving an operat-ing voltage +El, and a second terminal 11 for receiving a source of re-ference potential.  The common connection between the second 3 and third S transistors is connected to an output terminal 19.  A first diode is is connected between a third terminal 13 for receiving a clamping voltage æ 2 and the common connection between the uppermost first 1 and second 3 transistors, the diode 15 being polarized for clamping this common con-nection from not going lower than +E2 volts.  A second diode 17 is con-nected between the third terminal 13 and the common connection between the lowermost third 5 and fourth 7 transistors, this second diode 17 being polarized for clamping its associated common connection-to a maximum voltage of +E2 volts.  The difference between the operating and clamping voltages (El-E2)  is set to be less than the VCEX of the four transistors 1, 3, 5, 7 (breakdown voltage from collector to emitter with some backbias voltage on the base), thereby permitting the switching of an operating voltage or load voltages that are substantially greater than the VCEX rating of the transistors.  In one switching state only the second 3 and third 5 transistors are turned on  for providing bidirectional current flow between the voltage source of +E2 volts and a load connected to the output terminal 19.

Abstract: ABSTRACT                 The invention relates to an electronic relay arrangement and is suitable for use as a repeater in systems for single-current as well as double-current tele-graphy.  From the double-current telegraphy an arrangement is known wherein a bistable trigger circuit in the output circuit is switched over by a polarity change in the incom-ing telegraph line in response to which the flux through one of the transformers forming part of the transmission circuit changes direction.  The bistable trigger circuit of the output circuit is switched over by means of the resulting voltage pulse.  This arrangement has the draw-back that the input and output circuits require individ-ual, electrically isolated supply sources.  In addition, only polarity changes are detected and transmitted which causes the noise sensitivity to be increased.  According to the invention the input circuit comprises a current switching device which response when a threshold current value of the telegraph line current is exceeded and causes then a current, having a predetermined constant value, to flow through the transmission circuit.  The electrical isolation by means of the transmission circuit can be effected by, for example, a light-emitting diode and a photo-transistor.
