Granted: 1988-05-26
Abstract: A flat disc 1 having a central aperture is deformed on its periphery by spin-forming the metal of the disc so that the metal projects from each side of the plane of the disc and thereby forms a cylindrical rim 6 which is parallel to the axis of the disc. One or a plurality of series of V-grooves 8 are then formed on the outer surface of the rim. The metal is spin-formed in such manner as to cause it to be laterally extruded thereby forming a rim which has a definite thickness independent of the thickness of the initial disc constituting the web of the pulley.

Abstract: An apparatus particularly suited for measuring the shape or contour of a surface under load, such as a mattress, is comprised of a humanoid having body limb extremities which are movable in a manner similar to the movement of comparable human extremities. Sensors are placed at joints, such as the knees and hips, to measure the amount of relative movement, i.e. deflection, that occurs at these joints when the humanoid is placed upon a mattress surface. The sensors provide an indication of the shape or contour of the mattress surface by correlation of the relative movement that occurs at these joints caused by the underlying mattress shape. In its preferred form, a movable frame is provided to raise and lower the humanoid in relation to the mattress surface to be tested. A "spine" is also advantageously provided with associated sensors to measure deflection, and thus surface contour, in the lower torso/abdominal region.

Abstract: The folded fix-on angle bracket (14) is made from a punched sheet. The latter has an upper, triangular suspension portion and two lower overlapping portions (4, 5) which are also triangular in shape. During the folding of the angle bracket (14) the lower triangular portions (4, 5) which form the base plate assume a mutually superimposed position and are seam-welded or spot-welded. The holes (7, 8) located in the lower triangular parts (4, 5) then also lie over one another. The angle bracket (14) can be used universally, e.g. for cross-bracing. It has, in particular, the advantage that it can be made from relatively thin sheet. It can be used, in particular, as a joist shoe, support foot, as well as a general connection-piece for cross-bracing, lattice-work or wooden support structures.

Abstract: A thickened organic polymeric composition useful for molding and capable of resisting post-molding shrinkage after being cross-linked comprises a cross-linkable base resin dissolved in an unsaturated monomer, and an additive resin selected from saturated polyesters and saturated amide waxes, the additive resin being crystalline at ambient temperatures and having a melting point (Tm) below a temperature (Tc) at which the base resin cross-linking reaction proceeds at a significant rate. The base resin and additive resin have only a partial degree of compatibility. When cooled from a temperature between Tm and Tc to a temperature between Tm and ambient the composition thickens, whereas, when it is heated to a temperature below Tc, it reverts to a flowable composition.

Abstract: The transducer contains three planar technology micromechanical sensor elements (X,Y,Z), each sensitive to motion in one direction. The elements are integrated into a crystal surface layer so that the three directions of sensitivity are mutually perpendicular. The basic mechanical elements of the sensors are torsion beams (1). The torsion beams carry inertial masses whose centres of gravity lie far outside the torsion beams' rotation axes. The substrate material may be a silicon crystal or the beams are of silicon. Piezoresistive resistances making use of the piezoresistive effect in silicon to measure the mechanical stresses are integrated in the torsion beams. Alternatively, the beam stresses are indirectly measured by a capacitive method.
