A competitive wrestling game that simulates a competitive wrestling match. The game includes a plurality of images which represent various wrestling action maneuvers, submission maneuvers, escape maneuvers, reverse maneuvers and substitute maneuvers. The method of playing the game comprises the competitors drawing images and the competitor determining when to display a predetermined sequence of images. The opponent must then display a counter maneuver and if the counter maneuver is unavailable, ...

A system for hemodynamic simulation comprises a vessel having properties of a blood vessel, a reservoir containing a quantity of fluid, tubing connecting the vessel and reservoir, and at least one pump for circulating the fluid within the system. Fluid can be tissue culture medium or blood analog fluid, and the vessel may include mammalian cells attached to its inside. A drive system, comprising two reciprocating drive shafts that are coupled by a cam, enables the uncoupling of pulsatile flow an...

This invention relates to improvements in the manufacture of devices applicable to dolls that simulate physiological functions. On exerting pressure on a tank of water situated in the interior of the doll, a tube which commences in the interior of the tank below the level of the water, conducts a small flow of the said water towards the interior of the mouth of the doll and surrounding areas, although in a position in the mouth in front of a second tube which commences in the interior of the tan...

A pendulum clock powered by direct current wherein a pendulum is functionally separated from a timekeeping movement for driving the hands of the clock. A unique separate electromagnetic motor for driving the pendulum is located below the timekeeping movement.

A toy stethoscope including a flexible yoke with earpieces on the outer ends of the arms thereof, flexible tubes respectively extending along the arms from the earpieces to one end of a cylinder having a reciprocable plunger therein to produce sounds simulating natural heartbeats, another tube connected at one end to the other end of the cylinder and the other end of the tube being connected to a bellows element adapted to be manually operated to compress and release one end of the same to succe...

An improved apparatus to enable a user to simulate skating, hereafter referred to as a skating machine, wherein the improvement involves the incorporation of a tension means connected at one end to the location of the intersection of a pedal connector bar and a crank to prevent the skating machine from locking or freezing when the pedals are at their most sideways positions. The crank is connected at its opposite end to a resistance means and the pedal connector bar is connected at its opposite ...

A transparent optical film made of a polymeric material has a first smooth surface and a second structured surface for providing a simulated beveled appearance. The structured surface of the film is formed of a plurality of spaced parallel grooves, each groove being formed by a first facet which is substantially perpendicular to the first smooth surface and a second facet which makes an angle between 1 to 60 degrees with the first smooth surface. The film may be affixed to glass, the adhesive ap...

The present invention describes a method for testing an electronic part which may be an integrated circuit by using an air brush spray gun to apply an atomized flux coating to the part. The purpose of the method is to simulate soldering and is used on only a sample of parts as part of a reliability procedure before subjecting the part to an additional stress test or before actually soldering the part. The method comprises the steps of: spraying each part with an atomized flux coating; heating ea...

A sneaker adapted to simulate the sight and sound of a snake is disclosed. Such sneaker comprises a sole and an upper surface, the sole having a periphery therearound with a front toe section and a rear heel end section. Further provided is an upper having a lower periphery coupled with respect to the periphery of the sole and having upwardly extending portions to generally encompass the foot and lower ankle of a wearer. An elongated tongue is coupled with respect to the upper. It also has a fre...

Since the prior-art is based upon analog circuitry, it uses sinusoidal frequency and/or amplitude modulation to simulate a rotating speaker at a reasonable cost. This invention uses a process based upon theoretically derived frequency modulation (FM) and experimentally measured amplitude modulation (AM) to simulate the rotating speaker. The main FM equation is based upon the Doppler effect and is equal to one over one plus a sinusoidal velocity coefficient. The main AM equation has a much narrow...
