Abstract: Abstract of the Disclosure A drive mechanism for linking the pistons of a heat engine to a rotating drive shaft includes a housing through which the drive shaft extends in rotatable fashion.  Secured to the drive shaft within the housing is a main bevelled gear.  A plurality of bevelled drive gears engage the main gear, each drive gear being secured to a gear shaft which extends through the exterior of the housing.  Secured to the exterior end of each gear shaft is a gear wheel, which meshes with a similar, free-wheeling gear wheel.  A pair of eccentric arms are secured to each pair of meshing gear wheels, their distal ends being secured to a block.  A piston rod is also secured to the block, so that the reciprocal motion of the piston rod may be transferred through the eccentric arms and the gear wheels to the drive gear and the main gear.

Abstract: ABSTRACT          A Christmas tree base or the like with a cross-shaped stand or the like, on the legs of which holders for the trunk or the like are provided, which by springs are capable to draw the holders to the centre of the base. A cam disc is located centrally in the base. The cams of said disc upon rotation in one direction push the holders outward from the centre.          Upon rotation in the other direction, the springs draw the holders inward to the centre whereby the holders with their upper portion abut the trunk. The holders are slidable on the legs with a certain plays so that a "chest drawer effect" arises upon abutment of the holders to the trunk and thereby locking is effected. The springs, therefore, can be dimensioned so small that the rotation of the disc in one direction or the other does not require much force, because the disc preferably is located in such a plane that it automatically neutralizes the action of the "chest drawer effect".

Abstract: (Case No. 6979) ABSTRACT OF THE DISCLOSURE    An acceleration servo control system for railroad car retarders in which a computed desired instantaneou  decelera-tion signal and a measured actual deceleration signal are compared and any resulting error signal is fed back through the servo network to adjust retarder braking pressures to achieve and/or hold the desired deceleration rate which will allow the cut of cars to leave the retarder at a selected speed.  The desired instantaneous deceleration is computed using an algorithm incorporating actual measured speed, the selected exit speed, the number of axles in the retarder, and the remaining distance-to-go for all axles of the cut over which retarder braking will be effective, and based on the principle of braking each axle-wheel unit throughout the entire retarder length.

Abstract: Abstract of the Disclosure A system for orientating a railway spike of the type having a head provided with a lip which projects at one location from the head.  It is important to ensure that the lip is aligned in a predetermined angular position so that when the spike is driven in a tie by means of an automatic spike driver the lip will overlie the rail flange.  The system involves holding means, such as an electromagnet for holding a spike and means rotating the holding means and spike until a light path defined between a stationary source and detector is interrupted by the lip of the spike at which point the rotating means, for example, an electric motor is deenergized.  Alternatively, deenergization of the motor does not occur until, in addition to detection by the light beam of the lip position, a switch indicating a complete 90° rotation of the spike is also activated so that one of the flat faces of the square section shank will face the rail.

Abstract: Abstract of the Disclosure An improved manhole concrete blockout for forming sewer pipe openings in the cast-concrete wall of a manhole where a hole is dug in the ground and at least one vertical hollow form is positioned within the hole and spaced apart from the surface which defines the hole and concrete is poured between the surface defining the hole and the form for forming a manhole wall.  A plurality of form sections are connected together so that their outer surfaces can be positioned to become a longitudinal extension of the outer surface of the form.  A blockout member is connected to the outer surface of at least one of the sections for forming an opening in the manhole wall, the end adjacent to the section being shaped to engage and conform to the outer surface of the section and the other end being shaped to conform to and engage the corresponding portion of the surface defining the hole so that an opening in the shape of the blockout member will extend through the wall when it is formed.  The outer surface of the blockout member gradually decreases in cross-section away from the section, and the sections are disconnectable so that when the wall is formed the sections can be removed individually inwardly so that the blockout member can be withdrawn from the opening formed in the wall.

Abstract: ABSTRACT A roller pump in which one or more hoses is compressed against an arcuate stator bearing surface by a plurality of rollers carried by a rotating rotor.  A shim is provided in generally opposing relation to the stator bearing surface to impart a hose compression offset force to the rotor.  In this manner, the forces imparted to the rotor remain substantially constant through-out its rotation.  In a preferred embodiment, a liner, which may be unitary with the shim, overlies the hoses to be compressed by the rotor to compensate for dimensional variations between the rotor rollers and for variations in the bearing surface and the hoses themselves.  The thickness of the shim, at its region of greatest thickness, approximates the combined thickness of the hose, when fully compressed, and the compensating liner.  Tabs are provided to extend from the shim to assist in maintaining the shim and liner in proper orientation relative to the hoses to be compressed.

Abstract: ABSTRACT OF THE DISCLOSURE A substantially load-free anchor lock rail fastening assembly is provided herein.  It includes an anchor lock and a rail anchor.  The anchor lock is adapted to form a part of a plate or attachment to a railroad cross tie or rail support.  The anchor lock is provided with cooperating abutment means for providing a loose connection with the rail anchor.  The rail anchor is unitary and is provided with cooperating engaging portions disposed thereon.  The en-gaging portions loosely engage the abutment means, thereby loosely engaging the anchor locks.  This enables the rail anchor to control both the vertical and the longitudinal positions of the rail without exerting compressive forces between the rail and the rail support, such substantially load free fastening of the rail leaving the rail free to float.  This cooperation permits limited vertical movement between the floating rail and the railroad cross tie.
