Abstract: DRILLING METHOD AND APPARATUS     FOR LARGE DIAMETER PIPE ABSTRACT OF THE DISCLOSURE        A method and apparatus is disclosed for installing a large diameter pipe--in the range of 30 inches diameter--for spanning an obstacle, such as a river, along an invert arcuate underground path.  An inclined drill rig, having a mud supply system and power pod, includes an angularly inclined ramp and driven car for crowding, without rotation, a pipe either pre-bent to a preselected and constant radius of curvature or a straight pipe into the ground.  The pipe at its head includes an articulated drill head, which by appropriate articulation, assures placement of the pipe along a radius of curvature equal to the pre-bent radius of curvature of the pipe.  The articulated drilling head includes a hydraulic system for articulating and driving the cutting head and pumping mud and tailing from the pipe path.  Two discrete mud systems are used.  The first mud system is utilized to entrain and carry away cuttings.  The second mud system is combined with a flared skirt about the point of the drill head articulation to provide a clean and high lubricity annulus of mud about the advancing drill string.  The density of the first mud system can be used to vary the drill string mass, while the density of this second mud system can be used to vary the density of the fluid in which the drill string is buoyantly supported. Serendipi-tously the forces of drill string mass and drill string buoyancy can be balanced with respect to one another to provide neutral buoyancy within wide limits, thus insuring a neutrally buoyant force to prevent comment forces of sticking encountered despite wide ranges of pipe size.     Advancement of the drill string occurs along an arcuate path of constant curvature from entrance into the ground to exit from the ground by crowding the large diameter pipe only (without rotation) to avoid pipe stressing due to either pipe rotation or change of radius of curvature in the pipe from end to end.  Provision is made to precisely monitor drill head site pressures and volume of materials introduced into and taken from the drill site to prevent sticking.

Abstract: ABSTRACT           A method for triggering an ultrasonic flow meter comprising a synchronized ring circuit, consists of periodically turning the ring circuit on and off by trigger pulses whose repetition period is varied within the range of possible changes of the repetition period of autocirculation pulses of the synchronized ring circuit until an auto-circulation pulse is matched with a trigger pulse.  At such point, the application of trigger pulses to the synchronized ring circuit is discontinued by matching the frequency of the trigger pulses with that of the autocirculation pulses via continuous automatic phase control of the trigger pulse frequency.   With no autocirculation pulses in the synchronized ring circuit, the application of trigger pulses is resumed.

Abstract: ABSTRACT OF THE DISCLOSURE This invention relates to a quickly assembled prefabricated metal concrete pouring form for slabs and the like that remains in place as an in integral part of the finished structure.   The basic elements of the structure are exterior wall sections with each containing a series of vertically-aligned pairs of slots arranged in parallel horizontal rows throughout the length thereof and which can be telescoped into overlapping relation to place selected pairs of these slots in registry with one another to receive the hook-forming elements of one or more types of connectors that lock the sections together in freestanding assembled condition.   Two of these connectors, namely, a ground stake and a detachable endpiece of a spreader subassembly both include a vertically-spaced pair of downturned hook-forming elements to effect the locking action while the corner sections employ horizontally-spaced pairs of horizontally-disposed tongues for this same purpose   each spreader sub-assembly includes a spacer formed of sheet metal folded to provide a base  and upstanding opposed walls defining a slot-like channel there-between.   One of the sidewalls is internally dimpled at each end with these dimples being designed to enter apertures in an apertured extension of the endpiece so as to adjustably and detachably retain the latter in telescoped relation within the channel   Partition walls structurally similar to the exterior wall sections are used between long spans separating the latter to produce a divider.

Abstract: Abstract of the Disclosure Disclosed is an improved means for attaching a detachable type of dust shield to a disc memory assembly so as to efficiently seal the access ports from dust and dirt, and yet permit easy detaching and attach-ing of the dust shield to the permanent housing.  This is accomplished by a projection and lip, one of each carried by each of the housing and the dust shield adjacent the periphery of each.  They lockingly engage when the dust shield is mated with the module housing.  Approximately diametrically opposed to the projection and lip is a latch and striker, one of each again carried by each of the housing and dust shield adjacent their peripheries.  When the edge of the dust shield adjacent the latch and striker is pushed toward its mated position with the module housing, the latch engages the striker, locking the dust shield to the housing.          The latch incorporates a release mechanism allowing it to disengage the striker, releasing the dust shield from the housing.  Decreasing width guideways which engage lugs adjacent the projection can be used to guide the projection accurately to the lip.  By forming the projection and/or the lip with a ramping surface, the radial movement of the shield with respect to the housing can force the edge of the shield's mating surface against the similar surface of the housing, thereby assuring a tight dust-free fit.
