Abstract: A device for adjusting two butt ends of rails to be connected by welding comprises a rigid structure which is formed by two support plates. The support plates are aligned and interconnected by a concave part and which is able to be disposed horizontally so that the two support plates are pressed one against one vertical side of the head of one of the rails and the other against the corresponding vertical side of the head of the other rail. The concave part provides a region for access around the butt ends. Each support plate is provided with a retaining clamp which is provided with a jaw able to bear against the opposite vertical side of the head of the rail.

Abstract: A B S T R A C T         An earth leakage protection device comprises a core balance current sensing transformer having a secondary winding in which a fault signal is generated in response to leakage from AC supply lines forming primary windings of the transformer, an operational amplifier for amplifying the fault signal, a precision rectifier circuit comprising a pair of operational amplifiers for performing full wave rectification of the amplified fault sig-nal, delay circuit in the form of a two stage RC network which delays the rectified signal according to an IDMT characteristic, and a trigger circuit in which the delayed signal is compared with a preset reference signal by an operational amplifier to provide a control signal which actuates a safety device in the AC supply lines via a relay when the reference signal is exceeded. Within its operating range the device actuates the safety device much more slowly for lower leakage currents than for higher currents, and since it is operative on both halves of the AC leakage current signal the device provides reliable protection against the possi-bility of dangerous electric shocks while avoiding spurious trip-ping.

Abstract: ABSTRACT OF THE DISCLOSURE     An improvement in buoyant marine devices, such as pyrotechnic markers, the displacement of which normally decreases during operation as a result of weight loss. The device is provided with a ballast means and means to enable the ballast compartment to fill progressively with water whereby, during operation, displacement of water by the marker is maintained to a degree which will ensure that the device remains in operative orientation.  In this way, the problem of tilting by marine markers because of a gradual decrease in weight, to the point that the marker may be easily submerged by water and its operation thereby hampered, is significantly reduced.

Abstract: ABSTRACT OF THE DISCLOSURE     The present invention is directed to a system which reduces the loading of the vehicle engine when the manifold vacuum pressure is less than a predetermined threshold level without requiring action by the operator to effect this shedding of the load.  In addition, the invention incorporates monitoring apparatus in the system, to provide indications of the operator's inability to maintain a relatively high engine operating efficiency as indicated by the number of times the vacuum pressure decreases below the threshold level.  Also the invention provides an indication of the time that the vehicle is operated in this less efficient condition.  The information is available to the vehicle owner at the end of the period of operation and thus enables him to determine the habitually inefficient employee-operator of his vehicles.

Abstract: 039.126                 SIDE SHIFT PLOW ASSEMBLY     ABSTRACT OF THE DISCLOSURE     An implement side shift assembly is disclosed for laterally shifting an earth-working implement relative to a tractor or the like. The side shift assembly includes a frame assembly having laterally extending upper and lower slide rails. An implement support bracket mounts the implement to the slide rails for lateral movement. A slide plate is slidably mounted between the slide rails for lateral movement, and a piston-cylinder is connected between the frame assembly and slide plate to move the slide plate laterally. A latching mechanism mounted on the implement support bracket selectively connects the slide plate to the implement support bracket at one of a plurality of connecting points on the slide plate. One of the features of the invention resides in attaching lift cylinders to the side shift frame assembly at positions as far outboard as possible on the opposite ends of the frame assembly to reduce the bending and twisting moments on the frame induced by the implement. A further feature of the invention resides in a hose tensioning device that permits a relatively large amount of hydraulic hose for the implement control cylinders to be fed out or retracted for accommodating the movement of the side shifting implement.

Abstract: Selector valve Abstract A valve spool of a selector valve is selectively movable between a multiplicity of operating positions for controlling fluid flow from an inlet port to a plurality of signal ports and from the signal ports to a drain port.  At some of the operating positions of the valve spool, communication is established between the inlet port and one or more of the signal ports and between the other signal ports and the drain port through arcuate pockets in the spool instead of annular grooves normally associated with linear movable spools.  The use of the arcuate pockets and angular spacing of the signal ports permits the travel distance of the spool to be relatively short while maintaining the multiplicity of operating positions.
