Abstract: A ball-and-stick model system representing alpha carbon positions and the peptide link between adjacent alpha carbons as modeling elements of two-piece sets. Each two-piece set comprises complementary ring rods and ball rods, the latter having a generally cylindrical body enlarged at one end to a sphere form with a slot through a portion of the enlargement. The ring rod also includes a generally cylindrical body with an enlarged end portion to fit snugly within the slot of the ball rod so that when they are fitted together they appear as a sphere with the cylindrical body portions extending outwardly therefrom. The cylindrical portions of adjacent model sets are united by a pintle and hole structure configured so that when fitted together a continuous cylindrical body extends between adjacent spheres.

Abstract: A family tree panel which includes a plurality of insertion slots arranged each at one end of a plurality of interconnected branches is used to generate a family tree representation. A plurality of insertable tokens containing facial indicia representative of a particular relative is used to insert within the slots within the family tree. A deck of special cards indicating historic cities, surnames, ancestors and various investigative methods, as well as inheritances, are used to determine the placement of the relative slots within the family tree. Both the paternal and maternal family history is portrayed within the particular slots on the family tree. A particular arrangement of the research cards and relative cards allows the players, in turn, to place the ancestral tokens on the tree. The first player to place all the tokens within the tree completes his or her family history and wins the game.

Abstract: Display equipment gives a representation of a three-dimensional body. A series of spaced apart panels (28) are mounted to a support structure (30). Each panel (28) carries representations (40) of parts of the three-dimensional body which occur in the plane occupied by the panel. The panels are transparent or open to allow the representations carried by the different panels to be simultaneously viewed by light passing through the panels, thereby giving the effect of seeing the three-dimensional body. The equipment can be used to give a three-dimension view of the interior structure of human or animal bodies by providing cross-sectional representations of the body on the panels.

Abstract: An inflatable umbrella is provided which may be collapsed and retained in the form of a small easily carried package when not in use, and which may be rapidly inflated to an operative configuration by the breath of the user or other air source.

Abstract: A simple, durable, inexpensive educational device for demonstrating the physical properties of colliding, accelerating and vibrating objects, especially suitable for use by educational institutions at or below the college level is described. The device consists of a pressure sensitive medium affixed to a hard flat surface which may be made to vibrate while one or more balls are made to roll on the surface, resulting in visible imprints in the form of dotted or wavy lines. The distance between dots or the individual undulations of the wavy lines serve to mark the positions of the balls at equally spaced instants of time, and thereby allow a determination of the ball velocities and accelerations without requiring compressed air, spark timers, or stroboscopic photography.

Abstract: Force-indicating legs adapted to be fitted to the pelvic assembly of an anthropomorphic dummy for use in the dynamic testing of vehicle passenger restraint systems. The legs permit the measurement of most of the skeletal forces that are likely to be experienced during dummy leg contact with a vehicle instrument panel or a knee bolster in dynamic restraint system testing.Each dummy leg has a knee joint connecting the simulated femur and tibia bones and an ankle joint connecting the simulated tibia bone with a simulated foot structure. Forces acting on the simulated femur and tibia bones are measured by load cells capable of measuring axial (Z axis) compression and tension loads, shear loads on both orthogonal (X and Y) axes, lateral and longitudinal (or vertical) bending moments, and torsional moments.

Abstract: A lawn umbrella having a substantially square shaped shade, the opposed corners of which are secured to respective first and second struts. A first of the struts has an outwardly bowed configuration to tense the shade and is positioned within a sleeve at the top of a rotatable mast. The second strut has an inwardly bowed configuration and is positioned within a slideway on the mast below the top. The inclination of the shade may be varied merely by moving the second strut within the slideway.
