Abstract: ABSTRACT OF THE DISCLOSURE      A walk from behind soil tilling machine including ground wheels upon which the machine may be moved and two rows of ground penetrating and pulverizing tines located to the rear of the ground wheels transversely to the line of machine movement.  The tines of the rear row have a larger cutting diameter than the tines of the forward row, and the rows of tines are driven in counter-rotating directions such that upon forward movement of the machine the tines of the forward row break the surface of the ground and penetrate the earth to a determined relatively shallow depth and the tines of the rear row thereupon penetrate the earth to a further determined depth, with the forward and rear rows of tines cooperating to completely pulverize both depths of penetrated soil, thereby permitting thorough tilling of the soil to normal garden depth with a single passage of the machine.  Both rows of tines in the illustrated machine are carried by a transmission housing which can be pivotably positioned relative to the machine frame for selectively adjusting the respective depths of penetration of the tines of the forward and rear rows.

Abstract: ABSTRACT There is provided a tailgate loader for a vehicle such as a truck.  The loader includes an upper arm means and a lower arm means, both pivoted at one end to the rear of the vehicle, and both swingable in a vertical plane. The arm means are in parallelogram linkage, and a platform is mounted on the short rearward arm of the parallelogram, so that it can swing between a stored position in which it overlies the upper arm means, and an extended position in which it projects rearwardly from the upper arm means. Power means are provided fox swinging the arm means about their pivot locations, and an opener assembly is provided for raising the platform from the stored position to a near-vertical position as the two arm means swing downwardly about their pivot locations.  The opener assembly includes a first connecting link pivoted at one end to the upper arm means at a location spaced a first distance from the other end thereof, and a second connecting link pivoted at one end to the lower arm means at a location spaced a second distance from the other end of the lower arm means, the second distance being greater than said first distance. The other ends of the first and second connecting links are pivotally connected together to form a knuckle.  As the arm means are lowered, the knuckle moves away from the upper arm means, thus pressing on and moving the platform toward a vertical position, so that the operator need not exert great force to swing the platform to its extended position.

Abstract: ABSTRACT OF THE DISCLOSURE             .           Equipment for continuous ambulatory peritoneal dialysis in which a solution container is coupled via flexible tubing to a patient's tube that communicates with the patient's peritoneal cavity.   The  equipment  includes  a  flexible,  foldable plastic dialysis solution container having a transfer port.  A flexible tube having a luer connector at its distal end extends from the transfer port, for connecting to a luer connector carried by the patient's tube.  The flexible tube carries a frangible member which normally blocks fluid flow but permits fluid flow after the frangible member is broken.  A particulate filter and a manually-operable clamp are in series with the flexible tube.          Peritoneal dialysis is accomplished by connecting the luer connector from a fresh dialysis solution bag to the patient's tube luer connector, breaking the frangible member, and opening the clamp on the flexible tubing.  After the dialysis solution is introduced into the patient's peritoneal cavity and remains there for a predetermined time, the solution is drained back into the flexible  bag,  the  luer  connectors  are disconnected  and  the foregoing steps  are repeated.   If desired,  once the dialysis solution has been introduced into the patient's peritoneal cavity, the luer connections may be disconnected and the patient's tube luer connector may be capped.

Abstract: RC-1547-m028 PROCESS FOR THE PRODUCTION                OF AROMATIC POLYESTERS     ABSTRACT           The production of oxybenzoyl polyesters is facilitated by the incorporation of a phosphite, particularly an organic phos-phite, during the production enabling the production of molded articles from these polyesters of improved appearance and excellent properties.                     BACKGROUND OF THE INVENTION           The present invention relates to an improved process for the production of copolyesters.  More particularly, it relates to a process for the production of oxybenzoyl polyesters of aromatic dicarboxylic acids, bisphenols and p-hydroxybenzoic acid compounds as the starting materials.         It is known that such polyester resins can be produced by various polymerization processes including suspension polymeri-zation and bulk polymerization.  Of these, the bulk polymerization process is perhaps the most desirable process in terms of economy.          However, since the aromatic polyesters have a high melting point as compared with aliphatic polyesters, such as polyethylene tereph-thalate, a higher temperature is required to maintain the aromatic polyesters at their molten state.  Consequently, the polymers are often colored and deteriorated in performance.         Much effort has therefore been expended on the develop ment of a process which eliminates the disadvantages discussed above and provides a polyester molding material from which articles of pleasing and uniform appearance and properties can be obtained.                        THE INVENTION           According to the present invention, there can be pro-duced a polymer having an extremely low degree of coloration and
