Abstract: ABSTRACT OF THE DISCLOSURE            A cartridge (7) for removing contaminants from a liquid comprises (a) a central inlet or outlet, (b) a circumferential outlet or inlet for radial flow through the cartridge and (c) a resilient, helically coiled plate (8) permeable to liquid.  One edge of the plate is secured at or near the central inlet or outlet, the other edge is secured at or near the circumferential outlet or inlet and means is provided for tensioning the plate.     The cartridge may be used in a filter. It may be modified by adding a fibrous layer to the coiled plate. This renders it suitable for use as a coalescer.

Abstract: ABSTRACT           A high temperature filter for separating finely divided solids from gas comprising an outer, refractory lined, and inner generally cylindrical vessels having an uncleaned gas inlet pipe, a clean air discharge pipe, and two gravel feed pipes, all extending into the inner vessel and a common solids outlet in the lower end of the outer vessel. Three elongated spaced apart louver assemblies are disposed within the inner vessel to provide therebetween spaces for this gravel. A gas inlet chamber is defined on one side of the inner vessel and is closed at its bottom end by a sealing closure plate, which extends from the air inlet side of the bottom end of the inner vessel to a track of a lower end of an outer louver assembly.  Sealing and connecting of the gravel feed pipes and the gas discharge pipe, respectively, to the inner vessel and between both vessels, respectively, provide for thermally induced differential movement.  The louver assemblies are supported by a track assembly connected to the inner walls of the inner vessel thereby permitting slidable movement of the louver assemblies frame.  When coarse and fine gravel fill the spaces between the louver assembly, finely divided solids are removed from feed gas entering the unclear gas inlet pipe as this gas horizontally traverses through the coarse and then the fine gravel held between the spaces of the louver assemblies and is withdrawn from an open ended gas outlet chamber on the other side of the inner vessel.

Abstract: ABSTRACT           Branched polyamidoamines bearing a plurality of pendant aminoamide moieties exhibit properties which are superior to the linear polyamidoamines from which the branched polymers are derived.  The branched poly-amidoamine is readily prepared by reacting a linear poly-amidoamine with an alkyl acrylate or methacrylate to pre-pare a polymer with pendant ester moieties.  The ester moieties are then reacted with an alkylene diamine or a polyalkylene polyamine to produce the pendant aminoamide groups.  The branched polyamidoamines possess exceptional utility as curing agents for epoxides; as demulsifiers in the demulsification of water in oil emulsions; as flocculants and dye retention additives, and to impart superior wet strength properties to paper.

Abstract: SUMMARY      Certain classes of aromatic sulfoxonium salts, such as dimethylphenacylsulfoxonium and acetanilinodimethylsulfoxonium hexafluorophosphates, have little or no effect on prolonged heating with O-glycidyl group-containing epoxides.  It has now been found that if a quinone, peroxide, or iodoso aromatic compound is also added, the sulfoxonium sales rapidly bring about the polymerisation of such epoxides and curing of such polyepoxides.

Abstract: ABSTRACT OF THE DISCLOSURE           This invention is an intrusion detector which uses codirectionally coupled CW leaky cable sensor techniques.          Successive sensors are connected serially through R.F. decouplers, and each is polled and is sent power from a control unit via the serial cables, through the decouplers.  The detector thus provides both intrusion detection and a secure data link.

Abstract: ABSTRACT OF THE DISCLOSURE       Shifting of a marine propulsion device transmission drivingly connecting a drive shaft to an internal combustion engine and including a rotatable member operable to shift the transmission between forward drive, reverse drive and neutral positions in response to rotation of a shift lever is assisted by a shift assistance arrangement including a pivotal actuation level connected to a push-pull assembly operated by a main control and a connecting link pivotally connected to the shift lever and to the actuator lever.  The pivotal connection between the connecting link and the actuation lever includes a slider element mounted for reciprocative axial movement relative to the connecting link and pivotally receiving a pivot pin on the actuation lever.  A pair of springs acting on the opposite ends of the slider element maintain the connecting link and the actuation lever in a normal position so they move together to effect shifting when the resistance to transmission shift is below a predetermined level.  The slider element, and thus the actuation lever, is displaced relative to the connecting link from the normal position when the shift resistance is above that level.  The shift arrangement also includes a switch which is carried by the actuation lever and is engaged to interrupt engine ignition by a pair of cams on the connecting link when the actuation lever is displaced the normal position only during shifting from either the forward drive position or the reverse drive position to the neutral position.

Abstract: Abstract of the Disclosure Pressure-sensitive adhesive tape, the adhesive layer of which is a copolymer of alkyl acrylate (e.g., iso-octyl acrylate) and acid (e.g., acrylic acid) and which differs from the prior art in its high acid content and the inclusion of a small amount of lower-alkoxylated amino formaldehyde condensate as a latent crosslinking agent. The adhesive does not become crosslinked until it is heated.  After the tape has been applied and heated to crosslink the adhesive, the resultant bonds have outstanding resistance to peel forces combined with surprisingly good resistance to shear forces, especially at elevated temperatures.
