Abstract: ABSTRACT OF THE DISCLOSURE A method of cation reduction by anode-assisted electrolysis comprises electrolysing cations in a cathode compartment of a cell in which the anode compartment contains ferrous ion as a reducing agent, with relative motion between the anode and the anolyte so as to promote contact of the anode with ferrous ion despite their mutual electrostatic repulsion, wherein the concentra-tion of the ferrous ion is from 1/2 to 10 g/l.  The relative motion can take the form of air-sparging.  The method can be used to produce copper metal from copper solution.

Abstract: III.  ABSTRACT       Disclosed is an air make-up unit mounted within the confines of a conventional outside wall of a frame build-ins between the 16" on-center studs.  The unit includes a rotary blower with a horizontal tangential discharge, the latter having heating elements therein and being encased in a vertical wall of insulation which extends within an insulated air chamber defined by a telescoping outer casing.  Positive air pressure is maintained within the building by air-pressure-sensitive controls located within the building and controlling the two-speed motor. The latter is thermostatically controlled to be operated at a slower speed when colder weather prevails.  It is also controlled and energized by a humidistat located within the building to force outside air into the building and diminish the humidity therein when needed.

Abstract: ABSTRACT OF THE DISCLOSURE       The present invention relates to a ink supply system for a ink jet printer comprising a primary ink supply source and a secondary or temporary ink supply reservoir connected in series to a ink transfer conduit which delivers the ink upon demand to the ink jets of the print heads.  The secondary ink supply reservoir comprises a thin flexible membrane which serves as the upper surface and which expands or contracts depending upon the amount of ink present in the reservoir.  The presence of a proximity device senses the movement of the flexible membrane so as to monitor the quantity of ink present in the reservoir.  The secondary reservoir acts as a static pressure regulator for ink entering the ink jets.

Abstract: TITLE         IMMUNOGENIC POLYSACCHARIDE - PROTEIN CONJUGATES                            INVENTORS                      Harold J. Jennings Czeslaw Lugowski ABSTRACT OF DISCLOSURE         Antigenic polysaccharides are modified to generate a terminally-located aldehyde group by controlled oxidation of vicinal hydroxyl groups, e.g. of unlinked terminal non-reducing sialic acid residues.  In some cases where there is a reducing end group, e.g. of the type N-acetylmannosamine residue, it can be made into the most susceptible site for oxidation by initially reducing it to its open chain hydroxyl form, e.g. N-acetylmannosaminitol.  The vicinal hydroxyl oxidation is controlled to yield a reactive aldehyde group which is then covalently linked to a free amino group of a selected protein by reductive amination.  The resulting poly-saccharide-protein conjugates are soluble and have been found to have enhanced antigenicity compared to the polysaccharide alone.  This terminal aldehyde:free amine group reductive amination can be applied to various polysaccharide antigens and various well-tolerated proteins, preferably protein immunogens.  For example, meningococcal group A, B and C polysaccharides have been linked to tetanus toxoid to give soluble conjugates which have been found to have advantageous immunogenic properties.

Abstract: Abstract of the disclosure The switching amplifier contains several amplifier stages (43),the output signals of which are summed up along a diodecascade (47) in order to generate an output sum signal having a high voltage.   The transformers (21, 23) used for direct-current decoupling of the input from the output of the amplifier stages are connected on the primary side to an alternating voltage source (22) and on the secondary side to a rectifier circuit (27, 31, 35).     The controlled switching ele-ment (39) is located between this rectifier circuit and the diode cascade.        By means of this arrangement saturation of the transformers by direct-current pulses is prevented and each amplifier stage can be modulated to 100% by using only one transformer.

Abstract: MULTIPLE ORIFICE BUSHING                   ABSTRACT OF THE DISCLOSURE A process for manufacturing glass filaments (15) in which the bushing bottom plate (12) has tips (20) depending therefrom and each tip (20) has a plurality of orifices from which glass filaments (15) are drawn.  The tips (20) flood individually on start-up or during operation, and the flood results in a single composite filament being formed from the orifices of that tip.  The composite filament beads down rapidly and is subsequently separated into individual filaments (15) by the use of a fluid spray directed against the composite filament at the tip lower face.  The fluid spray is utilized to momentarily quench the composite filament and is terminated once separation occurs.  Subsequent filament drawing is accomplished without the use of a cooling fluid and by the use of known heat exchange means, e.g., a flow of cooling gas.

Abstract: ABSTRACT OF THE DISCLOSURE         A control circuit for a DC capstan motor used for driving a tape having control signals thereon is adapted for accurate stopping of the tape during intermittent-motion operation.  A frequency generator coupled to the motor generates a frequency signal whose rate is proportional to the motor's speed.  A position signal generating circuit generates a position value that increments by steps upon occurrences of the frequency signal.  A clamp circuit clamps the position value to a clamping level upon detection of the control signals.  A brake start signal generator provides a brake start pulse signal when the position value exceeds a predetermined threshold, and this brake start pulse signal is used to commence braking of the motor.  In order to permit accurate stopping in both forward and reverse directions, the clamping circuit provides one clamping level when a forward mode is selected and another clamping level when a reverse mode is selected.
