Abstract: ABSTRACT OF THE DISCLOSURE Method and apparatus are described for preforming the long edges of flat steel plate prior to the plate being formed, pressed and welded into large diameter pipe. In accordance with the method the edges are roll-formed while the plate is of excess width to provide material to serve as a lever arm during rolling, so that the metal can be suitably bent at locations spaced from the outer edges, and after forming the edges of the plate are sheared adjacent these locations to provide the preformed abutting edges suitable for the pipe.

Abstract: H. Kleiber et al -5-2-3 (Revision) Abstract of the Disclosure In navigation transmitters it is important that the phase difference between the carrier waves of a carrier signal and the carrier waves of sideband signals be held at a constant value.  To accomplish this, the carrier waves are maintained constant relative to a reference signal in a known manner.  A phase meter measures the phase difference between the carrier waves of the sideband signals and the reference signal and between the carrier waves of the carrier signal and the reference signal.  The measure values are used to determine the phase difference between the carrier signal and side-band signals which are compared with a desired value.          Depending on the deviation from the desired value, a controllable phase shifter controls the phase of the carrier waves of the sideband signals.  Since the measure-ments are made on a time-division multiplex basis, little circuitry is required.  Any measuring errors do not affect the formation of the desired phase difference.

Abstract: ABSTRACT OF THE DISCLOSURE        A wave energy extractor A wave energy device 10 incorporates at least one stabilising chamber 40 for influencing the motion of the device 10 in response to waves.  The stabilising chamber 40 is open at the bottom to the sea, and has a closable port 41 at the top of the stabilising chamber 40 for controlling air flow into and out of the stabilising chamber 40 resulting from changes in level of the seawater inside the stabilising chamber 40.  Appropriate timing of an opening and closing sequence of the port 41 is used to produce air pressure forces in the stabilising chamber 40 acting on the device 10 in a manner to control the heave and pitch components of the motion of the device 10.

Abstract: Abstract of the Disclosure The recovery of hydrocarbons from the cleanup of froth produced in the hot water process of removing bitumen from tar sands is enhanced by contacting the aqueous phase separated from the froth (i.e., the aqueous tailings) with a diluent for the bitumen, recovering an organic phase containing diluent and bitumen and recycling this material into the froth cleanup process.  The process is also applicable to the recovery of hydrocarbons from other aqueous tailings containing them.

Abstract: METHOD OF BRAZING HONEYCOMB AND PANEL ASSEMBLIES     ABSTRACT OF THE DISCLOSURE .       Rather than spray coat face sheets of honeycomb panels. with powder braze alloy or using foil strips of braze alloy between honey-comb core and face sheets, individual ribbon segment of brazing foil are positioned between succesive honeycomb cell vertices or nodes.  The arrangement is such that several such ribbon segments will lie essentially in parallel plants, to  each other and normal to the planes of the top and bottom panel sheets when these panel sheets are positioned to sandwich the honeycomb cells therebetween.  Heat can then be applied to melt the ribbon . segments resulting in a flow of the brazing material-into the ' nodes as well as the contact line joints made between the top and  '' bottom of the cell walls with the top and bottom panel sheets.  ,' Excess brazing material on the panel surfaces covering the open cell portions free of joints is thereby virtually eliminated and desirable ductility and elongation characteristics of the resulting structure are retained.
