Abstract: ABSTRACT A method for determining the position of a marine seismic receiver cable of the type which is towed behind a seismic survey vessel through the sea, wherein the azimuth and the distance from the vessel to points along the seismic receiver cable are measured, and the coordinates of these points are calculated on the basis of these values.  A hydroacoustic measurement method is utilized, based on a super-short baseline system integrated with a gyrocompass, for measuring the azimuth and distances in accordance with signals from trans-ponders, beasons, responders and/or similar instruments installed on or within the seismic receiver cable.

Abstract: -i-Abstract of the Disclosure An extension is provided at each end of a glue flap of a conventional carton blank, the extensions being glued to intentional carton dust flaps to thereby provide improved tamper resistance to a sealed end carton when intrusion is attempted along glue seam for purposes of violating the contents, i.e. pharmaceutical products and the like, contained within primary packaging contained within the carton (secondary packaging).  The extensions prevent withdrawal of the dust flaps to which the extensions are glued after the glue seam is penetrated.  If the dust flaps are forcibly withdrawn, positive visual indication of tampering will result to thereby alert a potential consumer.

Abstract: METHOD FOR INTERCONNECTING THERMALLY AND    PRESSURE-STRESSED MULTI-PHASE REACTORS                    ABSTRACT OF THE INVENTION    The invention provides pressure protection for the interior casing of hydrogenation reactors by the use of a manifold interconnecting the annular chambers of the aforesaid reactors with the processed-gas vapor path whereby process-conditioned pressure changes generated during the reaction process are simultaneously balanced.  As a result, the interior casings of the reactors which define the reaction vessel can be made of relatively thin material as compared to conventional reaction vessel.

The machine and method are characterized by an additional blow mold in tandem with one of the blow molds of the prior art two mold machine and method.  The machine is operated so that each longitudinally stretched portion of the tube on which the mold pieces of each blow mold closes has substantially the same extent of longitudinal stretch or elongation.  This is done by arresting the travel of the tube into the machine according to the distance of travel of the blow mold pulling it into the machine.

Abstract: S P E C I F I C A T I O N     "improvements in or relating to rotary drill bits"     ABSTRACT OF THE DISCLOSURE     The body of a rotary drill bit is formed from a matrix formed by a powder metallurgy process, and a plurality of cutting elements are mounted on the bit body, each cutting element being in the form of a disc of super hard material which is thermally stable at the temperature of formation of the matrix.  The front surface of each cutting element is engaged by a holding structure on the bit body in front of the cutting element, the arrangement of the holding structure being such that the resistance provided by the holding structure to forward deflection of the portion of the cutting element opposite the cutting edge is less than the resistance to rearward deflection provided by the surface behind the cutting edge.  Bending stresses imparted to the cutting element by rearward deflection thereof in the vicinity of the cutting edge are thereby reduced.

A master control unit is provided for performing individual and selected range checking and range conversion by reading of information from an internal memory of the master controlled unit which contains a data Descriptor Table with a table entry for each individually accessible data element in the main memory with two elements of each Descriptor Table entry assigned for range check and conversion purposes.  One of the elements permits one of the extreme limits of a value range of a data element in the main memory associated with a data Descriptor Table entry to be determined and the second element allows the number of values in the value range of the associated data element to be determined.          There is also provided a set of arithmetic circuits interposed in the data path to and from the main memory to be utilised for each read of write of information to and from the main memory. Thus the arithmetic circuits receive their input from the main memory and from the data Descriptor Table entry for a data element and deliver their output to the central processor unit by reading of information from a main memory and also receive input from the central processor unit and the Data Descriptor Table entry for the data element and deliver a corresponding output to the main memory.          The master control unit has means for generating an interrupt signal to the central processor unit in the case of an out of range value being detected.

The ribbon is introduced into a given curved path on a cylindrical drum (15). Arranged in the given path are suction openings which communicate with a suction source and are effective in holding the ribbon firmly by suction along the whole of its length, therewith preven-ting the ribbon from sliding relative the drum and the plastics web and from twisting or tilting on the drum despite the tension in the ribbon. Means (59) are provided for breaking the connec-tion between the suction openings and the suction source as the suction openings pass the end point of a given distance on the drum (15).
