Abstract: A B S T R A C T     Composite coupling devices for joining substrates comprising a preferably generally tubular heat-recoverable memory metal member, usually a radially heat-shrinkable member called a driver, and. a sleeve member positioned inside or outside said memory metal member, usually an insert,  to facilitate connection to the sub-strate(s) are constructed in such a way that the degree of recovery is higher than that exhibited by similar composite devices in which both driver and insert are simple tubular members. In preferred embodiments the driver is constructed so that it exhibits a bending mode of deformation, optionally in addition to a tensional or compressive deformation.  Typically this is achieved by forming the driver from pleated sheet, strip or wire.

Granted: 1978-12-12
Abstract: ABSTRACT OF THE DISCLOSURE      A variable draft, twin hull, column stabilized semi-submersible vessel comprises a pair of laterally spaced elongated hulls having at least 6 upstanding columns spaced therealong supporting a working platform in spaced relation above the hulls a distance slightly greater than the maximum anticipated wave height.  longitudinally spaced trusses, including transverse members, also connect the hulls.  The hulls buoyantly support the vessel in a low draft floating condition with the hulls having freeboard.  The hulls have ballast compartments to submerge the hulls and portions of the stabilizing columns to a distance of approximately half the effective height of the stabilizing columns which is slightly greater than maximum anticipated wave height, to maintain the vessel in a high draft floating condition with the platform elevated above the waterline.          The columns have a substantially constant cross sectional area throughout the effective length thereof and stabilize the vessel in the high draft condition about roll and pitch axes.  The working platform mounts either a drilling rig or a heavy duty crane or like operational equipment along the centerline of the vessel.

Abstract: ABSTRACT OF THE DISCLOSURE         A reminder card or bill rack, or the like, which has a frame and a pair of side-by-side vertically aligned series of card pockets on the frame.  Between the two series of pockets is a common vertical column of indicia on the frame dividing a given period of time, such as a month, into sub-increments, such as weeks, in alignment with the respective pockets.  The frame has a housing at the top thereof within which is mounted a pair of roller members, one for each vertical series of pockets.  Indicia is provided on each of the rollers, such as the twelve months of the year seriatim about the periphery of the rollers.  A window is provided in the housing for each roller so as to observe the indicia thereon.  Each roller is independently rotatable and has a handle connected thereto and exposed exteriorly of the housing for manual manipulation by a user.  In this fashion, when a particular given period of time has been exhausted, such as the month on the lefthand column, cards need not be shifted thereto from the righthand column, but the roller for the lefthand column simply may be manipulated to skip a month so as to provide indicia in the window one month ahead of the month in the righthand column.

Abstract: SPRAY AND FOAM PRODUCING NOZZLE APPARATUS Abstract An improved nozzle apparatus rapidly convertible, while operating, between spray and foam forming modes of operation. An elongate rigid generally cylindrical first con-duit member receives surfactant bearing solution at an inlet port thereof and directs the solution under pressure to a spray forming nozzle connected at an outlet port of the first conduit. A second elongate conduit member coaxially slidably overlies the first conduit member and is movable relative thereto between extended and retracted positions. When in its retracted position, the second conduit member exposes the spray-forming nozzle, which is then enabled to direct a spray pattern of the solution longitudinally outward from the appa-ratus. When in its extended position, the second conduit mem-ber encompasses the spray-forming nozzle, and aspirates the spray therefrom with air to form foam which is ejected longi-tudinally outward from the second conduit member. Fastener means connecting the first and second conduit members enables rapid positioning of the second conduit member between its retracted and extended positions. Handle means are provided for enabling an operator to hand-carry the nozzle apparatus and to directionally aim the spray and foam ejected therefrom to a target area. This invention respresents a significant improvement over the prior art in its ease of use and in its ability to rapidly convert between spray and foam producing modes without interrupting operation of the device.

Abstract: A B S T R A C T            A toroidal member is mounted on first frame means so as to be rotatable about its axis.  Second frame means are positionable adjacent the first frame means, the second frame means having means mounted thereon for feeding and depositing a strip of elastomeric material onto the surface of the toroidal member.  The means for depositing the strip of elastomeric material onto the surface of the toroidal member include a single layup wheel positioned adjacent the toroidal member to press the elastomeric material thereagainst, As the toroidal member rotates about its axis, a micro-switch is tripped by the leading edge of the strip of elastomeric material deposited on the surface of the toroidal member, and the sensing by such switch actuates a cutting apparatus for cutting the trailing end of the strip of elastomeric material, such cutting taking place so that the trailing edge is deposited on the surface of the toroidal member in end-to-end relation with the leading edge deposited on the toroidal member.

Abstract: ABSTRACT OF THE DISCLOSURE      Improved supported thallium reagents are provided which signifi-cantly improve reaction rates and product selectivity of oxythallium reac-tions.  The supported thallium reagents have a thallium salt of a Bronsted acid on the surface of and within, montmorillonite clay minerals, the rea-gent containing from 0.5 to 50 percent by weight thallium at least 75% of which is in the +3 oxidation state.  The montmorrillonite clay preferably is an acidic montmorillonite having a surface area greater than 200m2/gram. The supported thallium reagent may be prepared by contacting the montmoril-lonite clay with the thallium salt in a mixture of methanol and trimethyl orthoformate and then removing solvent under reduced pressure until a free-flowing power is obtained.  In use, an improved oxythallation of a nucleo-philic organic compound containing an olefinic, acetylenic or carbonyl group or carbon-nitrogen double bond by reaction with an electrophilic thallium (III) salt, is provided by supporting the thallium salt on the montmorillonite clay mineral, the montmorillonite supported thallium rea-gent containing from 0.5 to 50 percent by weight thallium at least 75% of which is in the +3 oxidation stats.
