Abstract: ABSTRACT OF THE DISCLOSURE         A machine for removing old rails and replacing them with new rails comprises an adzing station where the surfaces of the old ties are adzed after removing the old rails and tie plates.  The adzing station comprises two adzers spaced laterally on either side of the centre of the machine for adzing laterally spaced locations at which new tie plates and rails have to be laid.  The adzers are mounted, respectively, on two frames which can move together laterally with respect to a third frame in response to a centre line follower so that the adzers are always located at the correct lateral position even on curved track.  The third frame is attached to the main frame of the machine and it can be pivoted selectively about two spaced lateral locations adjacent to where the adzers are mounted in response to control signals from an inclinometer mounted on the pivotal frame and control signals from a superelevation device measuring the superelevation of the track.  Thus the adzers are maintained substantially perpendicular to the ties for all conditions of cross-level including superelevation on curves.

Abstract: VALVE ASSEMBLY     ABSTRACT OF THE DISCLOSURE         There are disclosed herein several embodiments of a pressure responsive discharge valve assembly particularly adapted for use in reciprocating type gas compressors.  The valve assembly includes a discharge passage valve seat of frusto conical shape in which a gen-erally complementary shaped light-weight valve member is disposed. The valve member is preferably formed from a polymeric material, but may also be formed of metal.  The materials used and the relative geo-metry of the valve seat and member are such as to reduce clearance or reexpansion volume, provide quiet closure with good sealing, long life and high speed operation, and still have the required flow areas at low valve lifts, thereby providing improved n ow characteristics and efficiency.  The included angles of the valve and seat are slightly different to provide progressive closing and sealing without permanent deformation.  The valve concepts are also disclosed embodied in two other known types of valves in which the valve element is provided with a central opening and associated closure means to provide additional discharge flow area.  The closure means in one embodiment is in the form of a fixed member and in another embodiment is in the form of a second separately biased movable valve disc member.  The discharge valve of the present invention is also shown in combination with several different types of known suction valves.

Abstract: ABSTRACT OF THE DISCLOSURE          A device is disclosed for contact-free thickness or interval measurement wherein a light source generates a light ray beam which is periodi-cally deflected.  A beam divider divides out a light ray beam for reception by first and second light-sensitive detectors which receive light only along a specific optical axis.  At least one third light-sensitive detector is pro-vided whose optical axis intersects the light ray beam at a reference plane. Electronic evaluation means are provided for generating from signals of the first, second, and third detectors a control voltage corresponding to a deflection time of the light ray beam and also at least one voltage impulse which is a measure of an interval of a surface of a measured object from the reference plane.  A reference voltage is provided and means are provided for generating a corrected reference voltage by changing the reference voltage in a direction opposite to a deviation of the control voltage from a normal operating voltage.  An impulse/digital converter receives the voltage impulse and provides a digital output which is connected to a digital/analog converter which creates an analog output based upon the corrected reference voltage and the digital input.
