Title: Toy sphere with rotating wheels
Inventor: MADDOCK PAUL T
IPC: A63H33/00
Filed: 1994-08-26
Abstract: A toy sphere consisting of a plurality of wheels that are rotatable around the radiuses of the sphere, each radius is in an even array of 45 degrees around the polar co-ordinates of the X, Y, and Z axes to form an array of eight wheels in each axis, where the circumferences of the three axes cross on the sphere, six wheels are made common to three axes of the said sphere, thus providing a total of eighteen wheels which are sized to 45 degrees of the circumference around each axis with the outer shape of the wheels conforming to equal 0.78539 radians.          Each wheel is pulled inwards by equal spring tension to the centre point of the sphere to ensure that the periphery of each wheel abuts the neighbouring wheels and provide sufficient tension that when one wheel is rotated all the wheels around the sphere drive their neighbouring wheels into rotation.  Decals can be attached to the front surface of the wheels to illustrate different colours and symbols which can be rotated at random to provide puzzles to amuse children of all ages.

IPC: C09D5/02
Filed: 1993-08-13
Abstract: The present invention provides a water-borne coating system comprising a top-coat polymer and a base-coat polymer each in dispersion, and including a component that results in increased mobility of the top-coat polymer relative to the base-coat po-lymer. Preferably, excess surfactant is used to increase the mobility of the top-coat polymer by the formation of micelles, and the curing agent acts to aggregate the base-coat polymer before the curing reaction and whilst segregation occurs. Suitable surfactants include ethylene oxide copolymers and ethoxylated nonylphenol. Preferably non-ionic stabilisation is used for the top-coat dis-persion.

Title: Heat-shrink crimping device and method
Inventor: BLONDER GREG E
IPC: H01R4/72
Filed: 1995-11-08
Abstract: In order to establish a low-electrical resistance between two wires, a heat-shrinkable hollow tube is prepared. Three or more small-diameter conductors are attached to the inner surface of the hollow tube, such as by means of an epoxy adhesive. These conductors run parallel to the axis of the tube along its entire length (L). Each of the two wires is inserted into an opposite end of thetube. The tube is then heated to a sufficient temperature, such that when it cools it collapses and grasps both of the wires firmly, whereby the resulting electrical conductance between them (aided by the conductors) is enhanced.

Abstract: DMS present in the brain of individuals susceptible to cerebral amyloidosis disintegrate into DMS components to form cerebral amyloid plaques and other DMS components that are removed from the brain via circulating bodily fluids. Detecting the presence of these removed DMS components and/or antibodies thereto in circulating bodily fluids provides a diagnostic mechanism to determine the onset of cerebral amyloid plaque formation. Detecting the presence of these removed DMS components and/or antibodies thereto in circulating bodily fluids also provides a diagnostic mechanism to determine the efficacy of treatment regimes for preventing cerebral amyloid plaque formation. Antibodies also can be raised against isolated DMS components and subsequently utilized in a diagnostic method capable of detecting the onset of cerebral amyloid plaque formation.

Abstract: A fabric for use as a base fabric in an air bag comprises a fibrous substrate having adhered to it a covering layer made of a thermoplastic synthetic resin and of 10 µm or less in average thickness. The adhesion between the fibrous substrate and covering layer is effected by causing the thermoplastic synthetic resin material of the covering layer to fill intersteces between the fibers of the fibrous substrate. This may be achieved by applying to the fibrous substrate a solution or dispersion of the thermoplastic synthetic resin. An air bag may be constructed entirely from the fabric such that when it comprises sheet material additional to the base fabric, these may also be provided by the same fabric as that used for the base fabric.
