A vehicle equipped with square wheels of the type contemplated by my invention gives better traction and a smoother ride when used on rough terrain than one having circular wheels. Following are the reasons: the sides of a square wheel constitute large flat surfaces for bridging ruts and cavities in the ground whereas a circular wheel follows the surface of the ground and enters many ruts; and the sides of a square wheel provide a large contacting area with the ground when they lie parallel thereto, and, hence, afford better pushing effect, whereas a round wheel affords only a small pushing area, which often results in causing a digging effect.

The invention relates to a projectile that is adapted to produce frightening noises while in flight, whereby such alien sounds will have a terrrifying effect on people nearby.

The psychological effects of weird or unexpected noises, which accompany an artillery projectile or missile, have been explored in many ways, prior to this invention, with minimum results. The Germans, in World War II, attached a noise producing device to aerial bombs, somewhat similar in construction to the organ pipe. A high pitched noise was created. This could be used only on large bombs and was too massive for use on artillery projectiles...

The insufficiencies of the prior art are overcome by the noisemaking adapter of the instant invention. The adapter ring is so designed that they attach to an existant missile without requiring modification of said missile. Centrifugal force, as a result of the spinning motion of the missile after being fired, causes the noisemaking arms or fins to extend and to produce weird, alien sounds of such magnitude as to be heard over a substantial area. The psychological effect, to create panic to those in the vicinity, is thus effected.

This invention relates to cavalry equipment; and it has for its object the provision of novel means for protecting the horse from the missiles of the enemy and in the provision of a cutting projection designed to injure the enemy or cause him to evade the projection by stepping to one side where an attack by the rider would be effective.

An embarrassing situation may arise, when people sometimes need to urinate and there may not be toilets readily available, for example when a person is driving a car on a highway, while touring a city with not public toilets readily accessible, while traveling in a bus, etc...

According to the present invention, a new shoe includes a container to store a person's urine. The person may use a standard catheter, which is connected to the container in the shoe.

This is an unobtrusive device, there is no bag attached to one's foot, etc. The device may be used discreetly, without attracting undue attention.

The present invention can provide a method and a system for the human interaction with plants. The present invention can also provide a method and a mechanism to animate by physically moving the plant in response to human voice or touch input. Additionally, the present invention can provide a commercially practicable method for humans or machines to assign personalities that will govern the plant's behavior.

The invention can provide an opportunity for retailers, distributors or gift givers to customize the behavior and content of the plant's behavior.

The present invention can provide a technique for the plant through its behavior to communicate its physiological needs for irrigation, light, fertilizer etc.

Among the objects of the invention is to provide a combined head covering and comb so constructed and arranged that the wearer of the head covering may comb up his hair coincidentally with the removal of the head covering from his head, and hence without rendering himself conspicuous in so doing.
