Abstract: UNIVERSAL SOLDERLESS TERMINATION SYSTEM            Abstract of the Disclosure Disclosed is a solderless termination system for multi-contact electrical connectors.  The termination system generally includes an elongated U-shaped channel of thin conductive sheet metal having one or more tabs extending from the upper edges of the sidewalls which are shaped and folded into the channel to define smooth and substantially rigid constrictions for rupturing and separating the insulation from a wire inserted into the channel and thereafter establishing and maintaining electrical contact with the underlying conductor.  The tabs are formed so as to present a smooth, tapered lead-in region having a rigid rounded nose.  The nose provides a smooth transition toward a curved wiping surface extending vertically downward toward the floor of the channel, the lower portions of the tabs being retained in or near the floor of the channel to prevent flexing of the tabs in the face of axial forces upon the inserted wire.

Abstract: ABSTRACT OF THE DISCLOSURE       Iron containing aqueous, acidic solutions, such as acidic stripping solutions used to remove iron from organic extractants, are purified by subjecting the acidic solution to a hydrothermal treatment at elevated temperatures and pressures which cause the precipitation of the dissolved iron in easily separable form.  The hydrothermal treatment is accomplished at temperatures in excess of about 100°C. The process can be applied to acidic solutions containing the dissolved iron in the form of ferric sulfate, ferric nitrate or chloride and is particularly adaptable to acidic stripping solutions resulting from the purification of organic extractants employed to extract iron impurities from solutions obtained in the acid leaching of clays, ores and concentrates.

Abstract: SELF-STEERING APPARATUS    FOR SAILBOATS     ABSTRACT OF THE DISCLOSURE      A wind powered, self-steering device for sailboats of the type employing a main steering rudder and auxiliary steering rudder.  The wind vane pivots about an axis that is tiltably adjustable with respect to the horizontal so as to adjust the sensitivity thereof in accordance with the type of keel associated with the boat, its point of sailing, and prevailing wind and sea conditions.  The wind vane axis is also rotatably adjustable with respect to the center line of the sailboat to provide course adjustment.  when engaged for operation, the wind vane senses the relative ship-wind direction and, when a boat is off course, translates the wind forces on the wind vane into corrective movements of the auxiliary rudder to return the sailboat to course.      The self-steering device is characterized by the coplanar nature of the axis about which the vane pivots, about which the axis of the vane is pivoted and about which pivoted motion of the vane is transmitted to the auxiliary rudder.  The present invention is further characterized by the fact that a transmission is pro-vided to transmit the pivotal movements of the wind vane to the auxiliary rudder in a range of settable gear ratios which can be determined independently   of and in addition to the angle of tile selected for the wind vane and the sensitivity corresponding thereto.  The present invention is further characterized by an auxiliary rudder blade subassembly having a pendulum body pivotally mounted on an axis at an angle to the horizontal.  The pendulum carries the auxiliary rudder blade which pivots about an axis on the pendulum which axis is oblique to the axis about which the pendulum rotates.  Wind vane movements are transmitted to the auxiliary rudder blade whereby the force of water flow past the deflected auxiliary blade causes the pendulum to swing on its tilted axis.  The tilt of the pendulum axis reduces the angle of the auxiliary rudder blade to water flow as the pendulum swings resulting in a reducing force on the blade.  In this manner movement of the pendulum is transmitted to the main rudder in such a way as to cause the main rudder to correct the sailboat's heading as dictated by the deflections of the wind vane.

Abstract: ABSTRACT OF THE DISCLOSURE          The invention relates to a rotary assembly for a rotary disc filter such as is used for dewatering slurries or pulps.  A plurality of filter element segments is supported on a rotary shaft of the assembly and flow conduits communicate in flow conducting relation with the filter element segments.          The flow conduits are spaced circumferentially of the rotary assembly and extend axially of the shaft.  A plurality of cir-cumferentially spaced securing elements is selectively releasably affixed with respect to the rotary assembly circum-ferentially intermediate adjacent pairs of the conduits, so as to secure each of the conduits adjacent thereto with respect to the rotary assembly.  Each conduit is thus secured with respect to the rotary assembly by the pair of securing elements circumferentially adjacent thereto.  The pair of securing elements securing any one of the conduits is selectively releasable therefrom  for disassembly of that one conduit while the circumferentially adjacent conduit is maintained secure to the rotary assembly by means including others of the circumferentially spaced securing elements.  Thus the assembly may be readily selectively dismantled for servicing if required.

Abstract: IMPROVED BUBBLE DOMAIN TRANSFER SWITCHES                   Abstract of the Disclosure These improved current controlled transfer switches are particu-larly useful for changing the propagation path of very small bubble domains without requiring large amounts of transfer current.  The underlying prin-ciple is that the transfer operation occurs when the magnitude of the magnetic drive field used to move bubble domains has diminished to a small value, or is zero.  This means that the magnetic field due to current in the switch does not have to overcome the effect of the drive field and therefore can be very small while still being effective.  This is termed a "start/stop" operation and in one embodiment, current-assisted transfer is achieved by utilizing a change in the sequence of the magnetic drive field (generally an in-plane rotating field) at the time of transfer.  In another embodiment, a continuous "three-quadrant" magnetic drive field is used instead of the customary 360° rotating drive field.  This three-quadrant field cycle is also the normal cycle for bubble storage operations and bubble motion elsewhere in the magnetic circuit is not disturbed by the switching operation because all devices are designed to operate with only one type of drive field cycle, which is the three-quadrant cycle. Switches operating in accordance with these principles do not have to have a particular design; in fact, several different designs are illustrated.
