Abstract: ABSTRACT OF THE DISCLOSURE              A catalytic composition comprising a metal phthalocyanine composition of matter is prepared by reacting a 4-sulfophthalic acid with a metal salt, an ammonium donor and a phthalic anhydride or derivative thereof at 250 to 325°C for one-half to ten hours.  The catalytic composition of the present invention is a powerful oxidizing catalyst, especially suited for the catalyzing oxidation of mercaptan sulfur to di-sulfides.  Mereaptan contamination of hydrocarbons is a pre-vailing problem in industry as mercaptans are present in natural gases, gasolines, kerosene and fuel oils.  Mercaptans are objectionable because of their strong odors and their corrosive-ness.  The catalytic composition of the present invention appears different from the conventional phthalocyanine catalysts and is produced by a simpler and cleaner process.

Abstract: ABSTRACT     CANADA      A fixture for locating the conductors  of a multi-conductor flat, flexible cable relative to a multi-contact electrical connector prior to the simultaneous connection of each contact to an individual conductor of the cable includes a clamping bar having a surface adapted to extend across the width of the cable.  Side-by-side parallel flutes extend across the surface the flutes being spaced apart a predetermined distance on centre lines which extend normally of the surface.  Each flute has a centre of curvature and the centres of curvature of alternate flutes are offset with respect to the centres of curvature of the remaining flutes.  When the clamping bar co-operates with a support surface of the fixture to clamp the cable to the support surface, the conductors of the cable assume a zig-zag array as seen in transverse cross-section.  The clamping bar and the support surface form part of a cable support which is attached to but capable of limited move-ment towards and away from a surface of a connector support. When pressure is applied to the cable support a cable will be moved relatively towards the surface of the electrical connector from which extend a plurality of electrical contacts.  Conductor receiving portions of the contacts penetrate simultaneously the cable and establish electrical contact with the conductors.

Abstract: Abstract of the Disclosure A push-button operated electrical switch includes a push-button adapted to be operated by a user and a dome-shaped member formed from a piezo-electric plastics sheet.  The sheet has electrically conductive film electrodes on both of its faces, and the push-button has a shank aligned with the dome so that when the push-button is depressed the end of its shank acts on the curved apex of the dome to depress the dome.  The end of the push-button shank is curved, the relation between the curvature of the shank end and the curvature of the dome being so chosen as to give the push-button the desired operating characteristics.  The distortion of the dome which occurs as a result of the depression of the push-button generates an electrical pulse condition between the film electrodes which provides an output indicating that the push-button has been depressed.  Such push-buttons are suitable for use in a telephone key block which includes logic circuitry adapted to generate voice frequencies in response to the starting and stopping pulses which occur when push-button is operated.

Abstract: ABSTRACT OF THE DISCLOSURE    A stationary offshore platform is protected against damage from moving ice sheets by a conical shield sur-rounding the platform support structure and having means, such as a pneumatic biasing system, for raising or lower-ing the shield along the platform support.  A system of mooring lines, thrustors, or the like is used to rotate the shield about the platform support.  After an advanc-ing ice sheet contacts the narrower upper portion of the shield, the shield is raised so that a wider lower portion of the shield can exert an upward force on the ice sheet to break the ice into pieces.  The shield is rotated, while in its elevated position, to carry the broken ice with it to a location downstream from the advancing ice sheet. The shield is then lowered to dump back into the ocean the ice pieces broken by the upstroke of the shield.          Means are provided for heating the exterior surfaces of the shield to melt ice pieces sticking to it.

Abstract: ABSTRACT OF THE DISCLOSURE There is described a programmable gas flow control apparatus for use in atomic absorption spectroscopy. Essentially, an all pneumatic system is described which provides for a pre-determined flow of fuel and oxidant to the burner. The invention compensates for the variation in oxidant flow due to nebulizer adjustments by adjusting the oxidant flow to the auxiliary inlet of the burner. The invention utilizes a pneumatic computing relay which senses the oxidant flow to the nebulizer and simul-taneously adjusts the flow to the auxiliary inlet so that the total flow of oxidant satisfies the predetermined optimum rate. The constant monitoring of the nebulizer line by the computing relay allows for continual adjustment of the oxidant flow to off-set subsequent adjustments.

Abstract: ABSTRACT OF THE DISCLOSURE           A method for the design of a packing laminate and a packing laminate manufactured according to this method.  Pack-ing containers are often made from a laminated material in-cluding a relatively thick carrier layer on both sides of which thinner, liquid-tight plastic layers are applied.  During its conversion into a packing container the laminate is folded and especially when one or more layers are to be folded at the same time there is a great risk that cracks occur in the layer situ-ated on the outside of the carrier layer in the fold, which layer is severely stretched during the folding.  According to this invention the stretching of the outer layer is reduced by cutting through the carrier layer where the fold is to be made, so that the carrier layer can be compressed during the folding. This maxes the distance around the fold snorter for the outer layer so that the stretching is diminished and kept inside the stretchability of the material, which means that cracks can be avoided.
