Abstract: PROCESS FOR PREPARING A PURIFIED IMMUNOGENIC GLUCOSYLTRANSFERASE          ABSTRACT OF THE DISCLOSURE           Immunization of animals with preparations containing more purified forms of glucosyltransferase (GTF) results in the presence of antibody in saliva  demonstrable by functional inhibitions of enzyme activity and binding of radioactive enzyme.          Serum antibody was also present.    Immunized groups of animals had lower mean caries scores than comparably sham-immunized or nonimmunized control groups.  Local immunization with GTF of serotype c or g or a Streptococcus mutans reduces the coloniza-tion, caries, and lesions caused by infection with S. mutans of serotype g (strain 6715) or c, or with serotype g or c, or with serotype a or g, respectively.

Abstract: TITLE OF INVENTION WELDING ELECTRODE DISPENSER ABSTRACT OF THE DISCLOSURE         A dispenser for welding electrodes is disclosed. The dispenser comprises a tubular casing having a first internal elongate tubular cavity for storage of a plurality of the welding electrodes for dispensing one at a time therefrom.  A top end closure has an axial opening dimen-sioned to permit the passage of one only of the electrodes from the cavity upon manual actuation of an axially-reciprocal pusher rod engaging the lower end of the electrode.  The axial opening is provided with a friction grip disc which normally closes the opening, permits the passage of an electrode therethrough but exerts a friction grip on a stationary partly-dispensed electrode to prevent the same from returning to the cavity.

Abstract: TORQUE RESPONSIVE SPEED SHIFT   MECHANISM FOR POWER TOOL             ABSTRACT OF THE DISCLOSURE     A power tool speed shifting mechanism includes a planetary gear set wherein the ring gear is connected to the driven member of a torque responsive disengageable clutch.  The driving clutch member is keyed for rotation with the sun gear of the planetary gear set; and the ring gear is mounted in a one-way clutch to provide for unidirectional rotation of the entire planetary gear set at the speed of the sun gear when the torque responsive clutch is engaged.  The one-way clutch is mounted in an axially movable but substantially nonrotatable member of a torque responsive coupling.  In response to a predetermined torque being transmitted through the speed shifting mechanism the clutch members disengage to impose a reaction torque on the coupling through the ring gear and the clutch.  Axial movement of the one coupling member together with the ring gear holds the clutch disengaged whereby the planet gear carrier then rotates at a reduced speed with respect to the sun gear.

Abstract: ABSTRACT OF THE DISCLOSURE           The disclosure is directed to a spooling apparatus that can be threaded on the fly to anchor, controlling twist and wind filament onto a receiving spool. A receiving spool is non-rotatably mounted on a spool shaft for axial reciprocation. A lead-in pulley is spaced axially outboard with respect to the receiving spool and is oriented rotate about an axis sub-stantially perpendicular to the axis of the receiving spool. A flier is mounted to rotate concentrically about the receiving spool and presents a pick-up bead adapted to engage the feed run of the filament as it passes between the lead-in pulley and an orienting pulley located in proximity to the inboard end of the receiving spool.  The orienting pulley is coated such that the tailing run of the filament cannot be engaged by the pick-up head as it rotates with the flier although the canting of the orienting pulley disposes the feed run such that it will be engaged by the rotating pick-up head when the spool reaches a predetermined position along its range of axial reciprocation. The feed run extends through a cutting mechanism which severs the tailing run therefrom shortly after the pick-up head engages the feed run. Means are provided in association with the cutting mechanism to grip the severed end of the feed run after severance and until such time as it becomes anchored thereto by successive overwraps. Means are also provided to assure that the twist imparted to the filament by rotation of the flier with respect to the relative location of the lead-in pulley will not be transmitted across the lead-in pulley and into the run of filament extending between the source of the filament and the lead-in pulley but will, instead, be transmitted across the pick-up head with the filament as it is wound onto the spool.

Abstract: ,572 Circuit Means For Providing Multiple Audible Signals From An Audible Tone Generator Means ABSTRACT OF THE DISCLOSURE     A circuit for providing a plurality of distinguishable audible signals from an audible tone generator includes at least two gates wherein the output of one of the gates determines the type of audible signal produced by the audible tone generator in response thereto.  The circuit further includes a single control terminal for controlling the logical state the output of the one gate and for controlling the type of audible signal produced by the audible tone generator.  The absence of an electrical potential at the control terminal when power is applied to the circuit results in a latching of the output of the one gate and the production of a continuous audible signal by the audible tone generator.  The presence of an electrical potential at the control terminal when power is applied to the circuit results in a periodic changing of the output of the one gate and the production of an interrupted audible signal by the audible tone generator.

The housing assembly includes end structures closing the upper and lower ends thereof, a water and particle inlet for pressure communication with the pressure vessel of the apparatus leading downwardly into the interior of the housing assembly adjacent the closed lower end thereof and a particle outlet for pressure communication with the con-tainer of the apparatus leading downwardly from the inter-ior of the housing assembly adjacent the closed upper end thereof.  A particle supporting plate extends longitudin-ally within the cylindrical housing assembly between the end portions thereof and is fixedly mounted along the sides thereof between horizontally spaced diametrically opposed portions of the housing assembly.  A pair of paral-lel endless chains have upper operative flights which extend along opposite sides of the upper surface of the plate, lower parallel return flights and arcuate ends trained about sprockets carried by the housing assembly at the ends of the plate.  A series of spaced perforated particle moving structures extend between the chains and are operable during the movement of the chains through their operative flight to move therewith over the upper surface of the plate and upwardly through the space there-over defined by the upper periphery of the housing assembly so that particles introduced into the lower portion of the space through the inlet are moved positively upwardly through the liquid free surface and then discharged through the outlet in a condition in which the liquid has been substantially drained therefrom.
