Abstract: ABSTRACT OF THE DISCLOSURE         A rotary compressor is provided with annular oil traps between rotor bearings and the working chamber at the intake and discharge end thereof.  The traps are maintained under low pressure generally equal to the intake pressure of the compressor The oil traps communicate with a point near the intake of the compressor, whereby any trapped oil can be returned, either directly or through a storage container, to the lubricating oil feeding system.  The discharge of the compressor is provided with a pressurized separator in which the oil carried through the compressor by the compressed gas is trapped and returned back to the lubricating system.  The advance in the art is in that only short and relatively inefficient packing of the shaft will suffice because any oil leaking through the shaft bearings is safely recirculated.

Abstract: ABSTRACT OF THE DISCLOSURE           A resilient rail clip or fastener formed in a generally trapezoidal configuration from springsteel is provided for securing rail track to railroad ties that may be constructed from a variety of materials,  The trape-zoidal shaped resilient rail clip has a long edge for gripping the rail which when untensioned forms a type of sine shaped curve and which when tensioned to the rail, utilizing two spikes or screws per clip, transforms the sine shaped curve into a linear line that is biased flat against the foot of the rail.  The pressure of the two spikes or screws per clip in combination with the configur-ation of the springsteel dampen potentially harmful acceler-ation and deacceleration forces in the rail and frequency vibrations in the range of 800 to 1000 Hz which occur prior to and during train passage by absorbing and dissipating the forces while preventing lateral movement, creep, rotation and failure of the rail by utilizing the natural frequencies of the novel clip while minimizing track main-tenance by reducing deterioration of the rail tie.

Abstract: ABSTRACT OF THE DISCLOSURE      The invention is an improved process for preparing epoxy resin/phosphoric acid reaction products having high enough phosphomonoester contents to be water--dispersible (as base salts) and low enough free acid contents to yield water-resistant cured coatings.  The phosphoric acid is provided as an acid source material derivable by the reaction of a hydroxylic P-OH functionality-limiting agent (blocking agent) with phosphoric anhydride as such or as a reaction product thereof with less than six molecular proportions of water.  A resin solvent, which may also function as the P-OH blocking agent but otherwise is inert and accept-able as part of the final coating resin formulation, is employed as the reaction medium.  The epoxide/acid reaction is allowed to proceed, effectively in the absence of water, until the content in the reaction mixture of species indistinguishable from H3PO4 by base-titration has dropped to a minimum.  Then enough water to hydrolyze the phosphopolyesters present is added and the hydrolysis is carried out, thereby cleav-ing the ester groups formed from the blocking agent and generating the P-OH groups needed for salification.     29,160A-F

Abstract: PUSHBUTTON SWITCH ASSEMBLY          Abstract of the Disclosure A pushbutton switch assembly, for a keyboard, comprises a plurality of switch units each having at least a pair of superposed switch contacts, one of which is movable by an actuator to make or break contact. Each actuator is a hingedly mounted cantilever having a pushbutton at its free end.  When the pushbutton is depressed an intermediate part of the cantilever actuates the movable switch contact.  The cantilever is dimensioned so that the operating force needed at the pushbutton is only a fraction of that required to operate the switch contact directly.  Also the pushbutton travel is correspondingly longer.  Accordingly the assembly may use a relatively stiff, small travel type of switch unit, for example a snap-action spring plate or flexible membrane, yet provide at the pushbutton the "soft" action and long travel preferred by so many users.          In order that this can be achieved without sacrificing the compactness desirable in a keyboard array, the distal end of one cantilever actuator is arranged to extend across the hinge axis of the next adjacent actuator.                        -i-
