Abstract: Abstract of Disclosure A readily adjustable machine which continuously produces corrugated flexible metal tubing from very light gauge metal and of various diameters. A warping ring receives there-within a longitudinally corrugated narrow strip of formable metal of light gauge and warps the same helically to produce convolutions by means of a helical warping surface which ex-tends into one  the longitudinal corrugations.  The size of the tube produced can be varied by merely substituting a warping ring of a different size.  A uniquely shaped pair of die-forming rollers have lock-seam am forming surfaces which are adjustable relative to each other to provide variation in the degree to which the seam will permit and withstand axial torque.  The lock seam is constructed to be symmetrical about the neutral axis of the corrugation and about the slope line of the common corrugation leg of adjacent convolutions which it constitutes.  The lock is provided by its radially extending deformations in its longitudinal medial portions and terminal portions, with intermediate portions therebetween extending it about 60 degrees thereto.   The terminal portions extend around the bottoms of each of the U-shaped seam elements to further lock the in place.  A flying saw automatically cuts of predetermined lengths of the tubing.  The length of the sections to be cut may be varied by merely re-positioning a movable switch in the path of to tube.  The tube has a unique lock-seam which is constructed to withstand greater flexing, greater axial twist and more stress without damage and without opening, and is stronger.

Abstract: A method of fabricating a lead titanate piezoelectric surface acoustic wave substrate comprises combining lead oxide, titanium tetra-n-butoxide, lanthanum oxide, and manganese dioxide, with a hydrocarbon solvent and adding water to the combination to form a slurry in which titanium polyester is precipitated unto the lead oxide and lanthanum and manganese oxides.  The slurry is dried by heating to a temperature sufficient to remove the liquids therefrom but below the temperature at which an exothermic reaction between the included hydrogen, oxygen and carbon occurs.  A first calcining operation produces the exothermic reaction and forms lead titanate afterwhich the lead titanate is heated to and maintained as a temperature above that produced by the exothermic reaction. The lead titanate is then ground to produce powdered lead titanate and a second calcining is carried out to produce structural annealing of the powdered lead titanate.  Binder materials are added and the combination of powdered lead titanate and binder materials is cold-pressed into substantially planar substrates.  After removal of the binders by heating, the substrates are fired to reduce porosity and poled to impart a piezoelectric characteristic.

Gunn  and Rayburn Bushnell TITLE:  "Marine Pipeline Installation System"                   ASSIGNEE:  Gibson Welding & Construction Co., Inc.            (a Louisiana corporation) Abstract of the Disclosure An apparatus and system for simultaneously laying and burying pipelines as they are constructed in an offshore marine environment which apparatus is comprised of a rigid structural frame having skids to contact the ocean floor as the device is propelled thereacross.  A plow on the frame having a knife edge shear blade at its frontal portion cuts and parts the ocean floor forming a ditch.          The plow is vertically adjustable (to control the depth of cut) and pivotally adjustable (to control the angular attitude of the plow with respect to the supporting frame).  A combined water and air sparge trails in the ditch created by the plow and agitages the sediment falling back into the ditch to prevent the permanent settlement of solid matter in the ditch prior to placement of the pipeline therein.  The ditch is thus retained in an open configuration facilitating easy installation of a pipeline therein.          Structural vertical supports have adjustable guide members thereon to supportably receive the pipeline as constructed from a lay barge or like construction platform and guide the pipeline into the trench created by the device, as the device is pulled along by the lay barge, thus combining the pipe laying and burying operation into one relatively high speed process.

Abstract: Abstract:          In a method of manufacturing consecutive pre-tensioned concrete elements, e.g. concrete sleepers, in a long mould bed, reinforcement ropes are tensioned and closure members are placed between different elements. Prior to casting closure members which are so formed that two or more cast elements are joined together via bridges or shoulders projecting outwardly from the elements and surrounding the reinforcement ropes are placed in the mould bed at predetermined intervals. The string of cast elements is advanced to an element-separating station at one end of the bed where the elements are successively cut by means of a diamond saw or the like. The bridges between the elements are formed in a manner such that the reinforcement ropes are protected and a small, preferably the smallest possible section of concrete between the elements is severed when the elements are separated from the string of elements. The cast elements may be removed from the mould bed by lowering said moulds    and carrying the string of elements on movable conveying means. Alternatively the moulds    may be turned after the casting operation. The string of elements is then removed from the mould bed by pressing the string of elements down therefrom or by lifting the moulds.        The invention also concerns a mould bed for casting a string of consecutive elements of the abovementioned kind, said mould bed comprising conveying means for advancing the string of elements to a severing station at one end of the bed.

Abstract: IN THE CANADIAN PATENT OFFICE             Inventors:    PETER JAMES WILLIAMS     Invention:    IMPROVEMENTS IN CONTROL SYSTEMS FOR APPARATUS     ABSTRACT OF THE DISCLOSURE     Infra-red radiation detectors are used in gas turbine engines to detect radiation produced by the turbine blades giving an indication of blade temperature.  Above a given limit the signal produced by the detector is passed to the fuel control system to shut down the fuel supply of the engine.  An additional detector is provided which receives the same image as the first detector but is biased to detect radiation in the visible light part of the spectrum.   When incandescent particles pass through the field of vision of the detectors both show an increase in signal due to both types of radiation being increased during this transient event. The signal from the second detector is used to reduce the signal fuel the first detector by an amount sufficient to prevent the fuel supply being temporarily shut down.

Abstract: ABSTRACT                 A lift truck has a log handling carriage head carried by a vertically movable boom.  The boom is pivoted to the truck frame below the operator's cab to pro-vide a clear line of sight from the cab along the top of the boom to the carriage head in any position of the boom.  The carriage head comprises a pair of independently operable, vertically disposed, transversely separated, articulated claws,  The claws are pivoted to opposite side extensions of the outer end of the boom for improved visibility to the load.  Each claw includes a generally upstanding main car-riage member, a fork extending forwardly from a lower end of such member, and a tusk curving forwardly and downwardly from the upper end of such member.  The fork and main carri-age member of each claw pivot about a common transverse axis, and the vertical angle of each fork is adjustable indepen-dently of the other by pivoting its associate main carriage member independently of the other such member.  Each fork is free floating within limits relative to its main carri-age member so that when the fork contacts the ground, its main carriage member may be pivoted without moving the fork. A tandem hydraulic cylinder and crank mechanism pivots each tusk relative to its main carriage member between open and closed positions.  Each tusk is operable independently of the other.
