Abstract: A process for the direct decaffeination of aqueous coffee extract solutions by contacting the surface of a thin film of an aqueous coffee extract solution with carbon dioxide under supercritical conditions of temperature and pressure to thereby remove the caffeine into the CO2 and directly recover the aqueous coffee extract solution substantially free from caffeine. The contacting of the aqueous coffee extract solution and the CO2 is preferably effected by passing the aqueous coffee extract solution downwardly through a packed column, while passing the CO2 upwardly in countercurrent contact therewith.

Abstract: A subscriber's connecting network comprising a symmetrical power amplifier which is formed by two pairs of complementary transistors. Resistors having the same values are arranged in collector circuits of the transistors of the symmetrical amplifier for limiting the current in the subscriber's line. In addition, means are present for making the base voltage dependent on the collector voltage of this transistor so that a predetermined voltage is present between these two electrodes in the normal direction of operation. Finally a by-pass capacitor for the speech currents in the subscriber's line is arranged between two input terminals of the symmetrical amplifier. The invention is particularly suitable for a network in which binary signals are used for the generation of ringing signals and metering signals in the subscriber's line.

Abstract: A method for the production of impregnated paper from fiber suspension or pulp is disclosed. It comprises the formation of a paper web on a conventional papermaking machine followed by treatment of the web in the stage of having a residual water content of 6% to 20% with a mixture of a) 0.5% to 5.0% by weight of a silicone-free, adhesive-repellent surface-active agent, (b) 89.0% to 95,5% by weight of an elastomer or rubber-like polymer, and (c) 2.0% to 6.0% by weight of a paper softener and continuation of the drying-process until the paper is completely dried. The mixture is added in an amount such that the dried paper web contains 7% to 60% by weight of the mixture. The mixture may be added, particularly in the case of lightweight papers, to the web itself after its formation at a residual water content of 6% to 20%. Alternatively, a primary amount of the mixture can be added to the fiber suspension or pulp prior to the formation of the web, the amount being 1% to 12%, based on the dry weight of the fiber suspension or pulp.

Abstract: An improved brake for a wheel mounted on a spindle is of the type which includes a housing secured to the spindle with a plurality of brake discs carried by the housing for relative rotation therewith. A plurality of reaction plates are carried by the hub of the wheel for relative rotation therewith and the discs and plates are intervened in an alternating fashion to define a pack. A first piston is axially, slidably mounted in a bore with the housing to define a first expandable chamber therebetween. Hydraulic fluid is selectively introduced to and discharged from the first chamber to produce selective movement of the first piston axially relative to the bore to cause it to produce a compressive force on the pack. The improvement includes adding a parking brake feature by providing a different backing plate portion to the housing. An annular cavity in the improved backing plate slidably receives a second piston therein. The second piston is biased to cause an axial extension thereof to contact the first piston to produce a compressive force on the pack. The introduction of hydraulic fluid to a second chamber between the second piston and the cavity will axially move the second piston away from the pack, overcoming the biasing and preventing it from applying the compressive force to the pack.

Abstract: A control provision is provided for separating sheets of printed matter. An initiator serves to generate electrical pulses proportional to the transport speed, which are transformed into compensation times depending on the pulses of the operating delay time and of the fall delay time of the servo components, and which are connected to the servo components via coupling elements and following selection or control circuits. A transport means moves the printed material, a distributing guide is operated by the servo components and the sheets to be sorted out are removed independent from the speed of transport and without interference or disturbance of the other sheets.

Abstract: The battery feed circuit provides a balanced dc feed current (ITR) to a 2- wire telecommunications path. The dc current in each conductor is generated by bidirectional current sources (103, 104) each responsive to one of a complementary pair of first control signals (S1, S1) along with a second control signal (S2). The first control signals are generated by a feedback circuit (105) which monitor the differential mode voltage (VTR) across the path. To reduce power consumption, the first control signals are a nonlinear function of the differential mode voltage. Longitudinal balance is provided by the second control signal which varies the currents generated by each bidirectional current source by equal amounts. This second control signal is generated by a feedback circuit (109) which monitors the common mode voltage across the path. <IMAGE>

Title: Tanker modular assembly system - uses sections connected to cross bulkheads during repeated turning round vertical axis
Inventor: IVANOV JURY PETROVICH
IPC: B63B73/10
Filed: 1982-05-18
Abstract: The assembly starts from horizontal bulkheads to which are secured vertical pairs of sections. To mechanise the operation, once the cross bulkhead has been installed at the assembly station, a first section is installed vertically and connected to the bulkhead. The assembly is then turned round a vertical axis and a section (3) of the second pair is fitted and then turned once again to fit a third section. A final turn is used for fitting the final section completing the module. The support platform (7) with a tilting platform (13) may be supplemented by a second platform (20) which moves up and down and also rotates round a vertical axis of symmetry and is moved by bogies (8) forming part of the main platform (7). The tilting platform clamps (25,26) move in three mutually perpendicular directions to move the section across and along the tilting platform and lift and lower it relative to this. Segments (14) at right angles to the tilting platform base, facing the second platform, work with rollers (17) on rods (16) forming part of hydraulic power cylinders (15) used to drive the tilting platform.

Abstract: The invention concerns a method and apparatus for separating, folding and applying sticky labels from a tape.  According to the invention, tape is fed from a dispenser (2) containing a storage roller of tape, onto a mechanism that can be opened and consisting of two endless belts ((12, 15) in contact with each other.  A predetermined length of tape is fed onto the transfer mechanism and retained on this by suction.  The transfer mechanism (12, 15) is then closed with the labels, held by suction, in such a way that an end with a clear sticky bit sticks out.  The moving belt (15) inside the transfer mechanism is moved back to its start position and holds the folded label by suction.  The labels are brought forward thereafter by a mobile, suction-driven application device (23,24,25), whereby the application device, while holding the label, is put on an object e.g. a code mark, a newspaper etc. and pressed down with the label's sticky side against the object.<IMAGE>

Abstract: An apparatus for feeding roundwood into a rotating debarking drum through the inlet end of the barking drum utilizing a conveyor. The prior method presents the drawback that it is not possible, with a single feed device, to feed into the barking drum roundwood of different lengths but only either long, intermediate-sized or short logs. With the present invention, this problem has been solved in that the logs are positively fed by the conveyor, at low speed, into the lower part of the barking drum, through a feed cylinder.
