Abstract:
To provide a firefighters drone arrangement (20), such that the drones (21) are installed on an on-tank support base (32) on the top surface of the truck's (22) tank (23), wherein the hydrant (26) is extended through a carrier ring (27) at bottom of each drone (21), and pulled up while the drones (21) are released up. The drones set (24) can either use a set of two drones, such that the leader drone (29) is carrying up the tip of the hydrant (26) to spray toward the fire, while the second supporting drone (30) is carrying the hydrant's (26) extension away from the building, such that this arrangement (20) is used for firefighting of a fire blowing out of a fiat in a high rise building, or the set of drones (24) are to be made of three or more, to create an arc shape for the hydrant (26) over the inaccessible terrain toward a deep unreachable fire inside a forest.
Abstract:
To provide a reporter drone (20), to approach a specific speaker in-between audience inside a big hole, a stadium, or in an open yard, or to take photos, record videos, and registers sounds from inside a narrow location where the drone's body (21) or a reporter can not approach, or can not get in. A triple camera (22) assembly, and a mike-speaker screen assembly (23), are installed and based separately at the ends of a two separate retractable motorized aerials (24), (30), installed at the ends of the bottom of the body (21) of a normal drone (20). When a drone (20) is used for reporting meetings with persons, the camera's antenna (24) is moving in the reverse direction of that moved by the antenna (30) of the mike-speaker screen (23), such that the mike-speaker screen (23) moves toward a speaker (person) while the cameras (22) are keeping a distance from him to get manage to get a photo for him.
Abstract:
A Safety/stability tool (20) for a mini aircraft (21) is provided, the aircraft block is to be penetrated by two parallely rigid, tensioned, and fixed ropes (22) extending from the top of the facade, toward the bottom basket (23), wherein a set of four side cylindrical bearings (24) are surrounding each rope (22) at the top and lower surfaces of the block (21). The ropes (22) serve as a guide, over which the mini aircraft (21) is guided to glide. In case of emergency, wherein the mini aircraft (21) gets idle, the mini aircraft 20 would not fell sideways, but it will fell down toward a basket (23), which is provided by a collapsible net (25), and a spongy base (26), while the mini aircraft (21) itself has an air cushion (27) too, installed on its bottom, this arrangement prevents the smash of the aircraft (21), and may let it bounce up and down along the ropes (22), until settling down inside the basket (23).
Abstract:
To provide a rescue drone (20), for rescuing an idle drone (21), it consists of an adjustable length hook (22) to engage with the idle drone, to carry it away, an L- shaped metallic tool (27) to push the idle drone away from the middle of the road, or to help in repositioning it to be at a side that permits for the hook (22) to engage with it, an emergency light (SOS) (28), to assist while hovering over the idle drone located in a road, an electric shock stick (29), which is to be used against any person approaching the idle drone to steal it, a speaker (30) and camera (31), to assist a security person in a command center to assess the case, talk with and warn any person who is trying to steal the idle drone, or to advise and guide a volunteer who is trying to help and assist in rescuing the idle drone.

Abstract:
To provide a motorized cleaning apparatus (20), that is manually effective in adjusting the horizontal destance of a rotatable brush (21) from a facade according to its variable protrusions details. On each of the the right and left hands of a worker supporting chair, rails (24) are installed, supporting from the back balance blocks, and supporting from their top sides two slideable beams (26), holding a motor housing, which is linked from its front side to an intermediate shaft (30) via a supporting frame (31), a belt installed on a drive gear from the motor side drives the intermediate shaft (30), which is driving via its end gears the brush's shaft (39), using two toothed belts. To support the brush (21), its shaft is linked from its both ends to the intermediate shaft (30) through a two U-shaped joints (40), which are inserted inside the ends of the intermediate shaft (30) and the brush's shaft (39), wherein carrier bearings are installed in-between them.
Abstract:
To provide an electric reciprocating razor (20), that automatically simulates perfectly the manual operation, which is a reciprocating motion of the blades head (21), by the user to release the repeatedly accumulating hair in front of the blades head (21), that blocks the blades from shaving (cutting) more hair. A hand held wet razor (20) is modified. The tubular housing of the razor contains a battery, powering a drive motor, which drives a pinion gear (30), driving a crown (31) gear, which drives a camshaft. The cam (32) tapered side is pushing away a spring loaded follower (34), that by its role pushes the blades head (21) in a reverse direction, in relation to the shaving forward direction, while when the cam's (32) tapered side is rotated, such that the convex side of the cam's (32) becomes with a slight contact with the follower (34), the follower (34) is retarded back by the spring, pulling the razor head (21) in the same cutting direction.
Abstract:
To provide a machine (20) to simulate the actual wavy motion of the Earth (27) around the Sun (23), The simulator machine (20) consists of a fluid basin (22), containing a motorized cart (28) providing the Sun's forward movement, and carrying it at the top via a rotatable shaft (29). The fluid is transmitting the rotation of the Sun (23) toward the Earth (27), the forward movement and rotation of the Sun (23), rotates the fluid around the Sun (23) and decreases its pressure, the high pressure static fluid from behind the Earth (27) pushes it toward the Sun (23) due to the pressure difference, while the rotated fluid around the Earth (27) pushes it vertically outward. The resultant pushes of the two pressures pushes the Earth (27) tangent to the first elliptic track around the Sun (23), but as the Sun (23) is moving forward, the 2 nd half of elliptic followed by the Earth (27), will be shifted forward, creating with the first half a wave.
