Abstract: ABSTRACT OF THE DISCLOSURE         The combustion turbine compressor diaphragm is provided with  improved diaphragm box  seal.  A channel-shaped seal support  structure  is  affixed to  the  inner surface of the inner shroud.  The base of the seal support structure defines a plurality of grooves  for  receiving seal strips which may be rolled into position and mechan-ically locked, such as by peening.  Because the thickness of the seal support base may be increased over that of the inner shroud,  the box seal increases the flexibility of seal  design.   In  addition,  the  box  seal  improves  the structural rigidity of the inner shroud.

Abstract: Abstract of the Disclosure Apparatus for the dynamic in-circuit testing of digital electronic devices employs a hardware testing circuit that is set by a microcomputer which takes no direct part in the test, so that the test hardware speed is not limited by the computer speed.  The apparatus comprises a library of devices corres-ponding to the devices to be tested, the library including a ROM containing the information regarding the devices needed by the microcomputer for its purpose.  An internal interface or router receives signals from the test device that are input signals to its terminals and routes them directly to the corres-ponding selected device in the library where it becomes an input to that device also.  Signals from the test device that are output signals are routed instead to a comparison block where they are compared with the respective output signals from the library reference device.  The signals at each corresponding pin of the two devices are compared and upon the presence of a fault the apparatus stops and identifies the pin or pins on which a fault has been detected.  An external interface is provided to shift the signal levels as required between the test device and the TTL logic devices of the apparatus.  The signals are sampled during timed periods to account for different propagation times through the apparatus, and different operating speeds of the devices.  Provision is made for external or internal clocks, reset and ground connections.

Abstract: ABSTRACT CASTING METALLIC MATERIALS (REFERENCE FIGURE 1) A process for casting molten metallic material having a solidi-fication range of temperatures, especially alloys containing more than 80% aluminium, involves simultaneously stirring and cooling the molten material to a temperature between 0°C and 75°C above the liquidus temperature of the metallic material using hollow heat transfer rods (9) extending across a duct (4), down which the material is caused to flow.  The material is then caused to solidify with a substantially non-dendritic microstructure by rapidly cooling it in a continuous casting machine.         The solidified bar so produced may then be reheated at a steady rate to a point between its liquidus and solidus temperature until it contains between 30% and 70% (by volume) solids content but can still be manoeuvred without losing its shape.  It may then, with a minimum of delay, be rapidly formed into a solid article of any desired shape by, for example, casting in a pressure casting machine.

Abstract: Abstract An apparatus for transferring pipe between pipe racks and the drilling rig floor including a stationary trough located below and extending towards the drilling rig and a movable, inclined trough aligned with the stationary trough having one end supported on the drilling floor and the other end powered to move between a lower position for transferring pipe to and from the stationary trough and an upper position for transferring pipe to and from the drilling floor.  Two pair of racking legs extending between the pipe racks and the fixed trough are provided.  Each log has a cradling lug which moves up and down the leg powered by a hydraulic cylinder, thereby lifting the pipe along the leg.  Further, each leg is able to pivot in two directions about a pivoting structure.  The pipe when moving in the troughs is held at one end by a shovel member which is engageable by the buggy which travels along the stationary trough and is also engageable by the carriage in the inclined trough. The carriage in the inclined trough may comprise either a chain driven carriage having a latch portion engageable with a latch portion of the shovel member or may comprise two pair of arms which close around the shovel member and subsequently move the shovel member, and thus the pipe, along the inclined trough.   Two pair of dumping arms are positioned beneath the fixed trough at a location adjacent the racking arms.  These arms powered by fluid actuated cylinders pivot about a point on the stationary trough so that their outer end extends through openings in the stationary trough thereby engaging a pipe and moving the pipe out of the stationary trough to the racking arms.  An operator's station is pivotally mounted on top of the stationary trough.

Abstract: ABSTRACT           A self-closing valve has a housing with an inlet and an outlet and a valve piston supported therein.  The side of the valve piston furthest from the valve seat defines a relief chamber with the housing, the chamber being connected through flow channels to the inlet and the outlet which are so con-trolled in counter-flow by an auxiliary valve that the running time is determined by a retarded opening movement of the valve piston, closing being achieved by a rapid closing movement of the valve piston. The "on" position of the auxiliary valve control is achieved hydraulically with autoholding by the opening sequence of the valve piston by a pressure differential built up with the flow through the valve at a choke device.          Interruption of this autohold switches the auxiliary valve con-trol.  Any leakage flow that occurs at the autohold elements is passed unrestrictedly to the outlet through an additional valve that is opened when the auxiliary valve control is activated.          This additional valve closes after interruption of the autohold and the switching of the auxiliary valve control that occurs when this takes place, so that any possible bypass flow parallel to the flow through the choke device for the flow through the valve is avoided.
