Abstract: TRAVELING SLOT FEEDER                 ABSTRACT OF THE DISCLOSURE A bulk material handling apparatus includes a traveling slot feeder which runs on tracks at opposite sides of the endless belt conveyor beneath a row of bins permitting selective emptying of the bins.  The feeder includes inclined, shiftable side skirts which can be adjusted to vary the width and elevation of the unloading slot and an adjustable striker at the downstream end of the feeder which establishes the con-tour and height of the bulk material deposited on the endless belt conveyor.  The material handling apparatus may employ power means so as to permit remote control of the bin emptying operation and adjustment of the skirts and striker.  The in-vention is illustrated in a ship where remote control is a particularly desirable feature to reduce space for workmen in the bottom of the ship and to reduce exposure of workmen to dusty working conditions.

Abstract: Abstract of the Disclosure Polymers reactive towards free amino groups, such as polyamides, polyureas, polyurethanes or polyesters, are provided with durable modified properties by being brought into contact with an additive polymeric material which (a) is compatible with the polymer being treated, (b) contains a plurality of oxyalkylene groups effective to impart to the modified polymer improved properties such as reduced static propensity, modified dyeability, or greater water absorb-ency; and (c) has one or more reactive sites, in the form of a pandant free primary amino group or potential primary amino group, blocked by the dehydration of an aldehyde or a ketone with the amine, which in either case affords the capability in proper circumstances of attaching the modi-fying polymeric material to the polymer being treated by 8 covalent chemical bond.  Suitable modifying polymers are made by reacting a diamino or higher amino compound with a proportion of an aldehyde or ketone sufficient to block at least some of the amino groups present, oxyalkyl-ating the blocked starting material through a surviving amino groups to an extent capabit of affording the desired properties, and if desired, cross-linking or chain-extending the resulting material to obtain a substance of increased molecular weight.  Modifying polymers so made may be used as such (i.e., in the aldchyde- or ketone-blocked form) for treatment of the reactable polymer to be modified, either by blending into a melt or by surface treatment of freshly produced fiber or sheet material.  The formation of free amino groups in the modifying polymer can occur in situ when the modified polymer is exposed to water under suitable conditions.  The modifying polymer may also be used in a free amino form generated by hydrolyzing before bringing it into contact with the polymer to be modified.  Novel treated polymers arc thus produced which display modified properties which are retained despite repeated washings and/or long-continued use.

Abstract: BALANCING METHOD FOR USE IN MULTI-SPAN ROTOR       SHAFT SYSTEM AND BALANCING SYSTEM USING SAME     ABSTRACT OF THE DISCLOSURE          A balancing method for use in a multi-span rotor shaft system for a prime mover, such as a large-capacity, large-sized steam turbine and generator.  A balancing influence coefficient representing the relationship between a unit weight and vibration, when the aforesaid unit weight is attached to a given balancing plane of a multi-span rotor, is first determined, and then a balancing plane, to which is to be attached a correction weight, is selected, then a correction weight is determined so as to minimize values of residual vibration amplitude, by using the method of least squares, which values are dependent on the values of the initial vibration amplitude, influence coefficients and correction weights.  Thus, a weight corresponding to the aforesaid correction weight is attached to the aforesaid balancing plane to reduce vibrations in a shaft.

Abstract: ABSTRACT OF THE DISCLOSURE A fluid collection device for receiving a liquid, such as blood, and which is adapted to be centrifuged to separate it into its relatively light and heavy phases.  The collection device has a phase partitioning device having a specific gravity intermediate those of the light and heavy phases of the blood so that it automatically moves during centrifugation to substantially the interface of the phases to sealingly partition them from each other.  The device has a resilient sealing member which is of conical or "umbrella" configuration, and another member of different specific gravity connected to the sealing member and having stabilizing members for maintaining the sealing member properly oriented in the container.  The sealing member partially collapses during centrifugation to allow blood components to pass by the sealing member.  As the phases become separated and the centrifugal forces decrease, the sealing member expands radially outwardly and sealingly engages the walls of the container providing a barrier between the light and heavy phases upon complete phase separation.
