Abstract: APPARATUS AND METHOD FOR SPLINING POWER TRANSMISSION MEMBERS                 ABSTRACT OF THE DISCLOSURE     Apparatus and a method for splining annular thin wall power transmission members in a manner that provides precise spline formation and accurately maintains the roundness of the splined members.  A toothed pinion type mandrel of the apparatus mounts a power transmission member to be splined between a pair of cooperable dies of the apparatus.  Each die has at least one first tooth group and a second tooth group, and teeth of each tooth group are spaced therealong with the teeth of the first group spaced farther from each other than the teeth of the second group.  Driving of the dies relative to each other and the power transmission member mounted on the mandrel initially engages the farther spaced teeth with the mounted transmission member so as to cooperate in a meshing relationship with the toothed mandrel with the power transmission member therebetween to form a first set of splines.  Subsequent movement of the dies engages the closer spaced teeth with the power transmission member to mesh with the first set of splines therein while concomitantly cooper-ating in a meshing relationship with the toothed mandrel with the power transmission member therebetween to form a second set of splines intermediate the first set of splines.  Still subsequent driving movement of the dies again engages the splined power transmission member with the farther spaced teeth to mesh with the splines while skipping at least alternating locations there-between to correct any out of roundness of the member.  Annular power transmission members which include an end wall and a thin wall sleeve portion with an open end opposite the end wall are splined by two preferred embodiments disclosed.  Each preferred embodiment incorporates a pair of elongated gear rack type dies that are driven rectilinearly on opposite sides of the mandrel mounted member.  Partial teeth are located between the teeth of the first tooth group in an alternating relationship so that the full teeth of the first tooth group are spaced twice as far from each other as the teeth of the second group.  The partial teeth form end depressions between the first set of splines at the open end of the sleeve portion to maintain its diameter the same adja-cent the open end as adjacent the end wall.  In one preferred embodiment, the dies are reciprocably driven and subsequently mesh again with the first tooth group that forms the first set of splines so as to thereby correct any out of roundness of the splined member.  In the other preferred embodiment, another tooth group trails the second tooth group and has teeth spaced twice as far from each other as the teeth of the second group so that the out of roundness correction can be provided with the dies driven relative to each other in a single direction.

Abstract: ABSTRACT OF THE DISCLOSURE   A hydrostatic transmission control for a hydrostatic transmission having a variable displacement pump and a variable displacement motor in-cluding pressure-responsive displacement control means for the pump and mo-tor with a displacement control valve for each of the pump and motor and positionable by a control pressure to set the displacement of the pump or motor with which it is associated. In dual path control of two hydrostatic transmissions, a master circuit has a first valve for setting a control pressure to determine the speed of operation of the transmissions and a second valve for determining the direction of operation of the transmissions, with operation of both valves by a single control handle.  The master circuit connects into two branch circuits, each leading to the displacement controls for one of the hydrostatic transmissions and with each branch circuit having its own steering control valve.  The steering operation is controlled by an additional pair of handles associated one with each of the pair of steering control valves.  Each of the steering control valves provides for a reduc-tion in a control pressure for reduced speed of the associated hydrostatic transmission or reversal of flow of control pressure fluid to obtain the reverse direction of operation of one of the transmissions.

Abstract: ABSTRACT            Allergen-containing substances, methods of preparing the same and using the same as immunologically specific suppressants of the production of reaginic antibodies directed to the allergen in question are disclosed. The allergen-containing substances are according to the inven-tion characterized as covalent conjugates of the allergen molecules with non-immunogenic water-soluble polymers. The degree of conjugation is such that the conjugates are rendered tolerogenic as well as substantially non-aller-genic and non-immunogenic.            The new conjugates are useful for immunologically specific suppression of common allergies in mammals, including humans, which are mediated by reaginic antibodies of the IgE class.

Abstract: A HYDRAULIC ACTUATOR FOR A DRUM BRAKE     ABSTRACT OF THE DISCLOSURE         A drum brake assembly provides a pair of brake shoes which are movable by a hydraulic actuator to a braking position.  The hydraulic actuator is carried by a backing plate and the pair of brake shoes is movable relative to the backing plate.  A piston is slidably mounted within a bore on the hydraulic actuator and pressurized fluid communicated to the bore acts against the piston to move the piston and pair of brake shoes.          A partition is also disposed within the bore to substantially define a secondary chamber which receives pressurized fluid from the bore.  The partition is movably disposed within the bore and resiliently engaged with the piston so that increased pressure within the bore is trans-mitted to the piston via tile partition and the resilient engagement.          Moreover, the partition controls venting of the secondary chamber so that upon contact of the pair of brake shoes with a drum, backlash or retraction of the pair of brake shoes is limited.
