A two-wheeled cart for training trotters, wherein the cart frame comprises two longitudinal rigid thill members, which at a central part thereof are pivotally connected through a cross connecting member to be vertically rotatable in relation to each other, wherein each wheel is individually resiliently suspended at a rear part of the respective thill member, and wherein a seat supporting cart member is separately resiliently suspended by the cart frame. A device for adjustable loading of the car...

A training bar to be worn simultaneously by a sighted and a non-sighted runner. The bar comprises a central rod approximately four and one half feet in length having a shock absorber disposed at either end. A belt or harness to be worn around the waist of the runners is attached to each shock absorber with the sighted runner wearing the belt with one end of the bar attached at the rear. The non-sighted runner wears the other belt with the remaining end of the bar attached at the front, so that w...

A training projectile having an auxiliary drive mechanism for counteracting the aerodynamic resistance to which the projectile is exposed during the training flight phase of projectile travel. The auxiliary drive mechanism preferably is in the form of a rocket or jet drive. The training projectile is also provided with a mass so that the ratio of the resultant axial force to the mass of the training projectile is at least approximately equal to the ratio of the resistance force to the mass of a ...

A muscle toning, strengthening or exercising machine has an arm provided with grips or other body-engaging members and swingable about an axis defined by a shaft to which the arm is coupled. This shaft is connected to another shaft by a transmission having a selected transmission ratio and the other shaft is connected to an electric motor which controls the force supplied for exercising, e.g. via a crank mechanism.

An improved training doll for prospective mothers, sisters, child attendants and the like is provided which includes a life-like torso having the approximate weight, size and appearance of a baby, preferably a newborn infant. The torso has arms and legs articulated to it and including fold lines. The arms and legs are also of the proper approximate size, weight and appearance, to simulate a baby and include means in the form of surface patches for restricting movements thereof to life-like movem...

An apparatus for training a user in contamination surveillance. The contamination may be from a nuclear, bacteriological or chemical explosion or leak, for example. The apparatus is portable and can be carried by the user to various points of an exercise area. The apparatus includes a data store and an interpolation device. The data store stores data which is derived from a mathematical model of an assumed source of contamination and which defines the contamination levels at various locations wi...

A training panty (10) includes a pair of pants (12) having a front panel (14) and a rear panel (16) integrally joined together at a crotch (18). Releasable contact fastening members (30, 38) are positioned on opposing surfaces of front panel (14) and rear panel (16), respectively along the lateral edges thereof so that front panel (14) and rear panel (16) can be releasably secured together to define a waistband (20) and a pair of identical leg openings (22). In an alternative embodiment, front p...

A round of ammunition for use in training comprises a standard brass cartridge case (1) containing a reduced propellant charge (14) and a bullet (2) of standard shape comprising a core (3) of rigid polyurethane foam and an external skin (14) of unfoamed polyurethane. The core and skin can be moulded integrally. The round is designed for firing in an automatic weapon and actuating its automatic mechanism. The skin of the bullet should be not less than 0.02 mm thick to withstand handling, and not ...

An adaptation cartridge comprises a firing pin casing which is screwed into a cartridge chamber or cartridge chamber tube and is secured against rotation by a radially displaceable slide. The cartridge is used for training on a gun having a subcaliber barrel adapter.

A supersonic nonspinning training projectile has a projectile body extending along an axis and having axially spaced front and rear ends and an aerodynamic rod projecting axially forwardly from the front end of the body. Thus when the projectile is fired axially forward the rod creates turbulence effective laterally on the projectile body at a wind-attack point which moves axially forward from a rear point to a front point as projectile speed drops. It is possible according to the invention to v...
