This invention concerns a dental implant with an oval section which allows making implants in places which were not able to make it in them before, because its being narrow in one of the directions distal - mesial or lingual - buccal. The design allows a better cosmetic and gingival case when making implant operation in molar place where two implants are putted distal-mesial and in case of lower incisals. The implant provides high primal stability and big space for the attached surfaces and gives a high performance against the chewing forces.

A new technique to achieve anterior displacement of the retro positioned mandible synchronously the applying of fixed orthodontic appliance during the treatment of skeletal class II malocclusion. This technique utilizes the skeletal miniplates which are fixed bilaterally on both jaws; in the anterior maxilla and the posterior mandible. Intermaxillary elastic is extended between the hooks of these miniplates and applies a force of 400-500g in each side. The elastics are easily replaced every 12 hours by the patient.

The invention refers to an orthodontic expander for surgical rapid maxillary expansion comprising a middle part and two lateral parts. The middle part has two vertical holes to fix the appliance in the mid palatal area and three horizontal holes. The lateral parts comprise three vertical holes whereby an expansion screw is inserted in the middle hole. The lateral parts comprise wires which support and guide the expansion movement. Each wire moves either right or left separately when expansion screw is activated in one side.

This invention presents a simple and practical solution for disposing the condensed water from air conditioning units as well as improving the cooling cycle efficiency and without extra cost or complication in manufacturing and without over power consumption. Improving the efficiency means raising the amount of heat taken from the medium, in other words, reducing power consumption. A water container which is connected to a drain pipe has many holes on the bottom. The water container is located above the condensers pipes of the outdoor unit and disposes the water condensed on the evaporator.

- a radiator, - a fan with motor at the bottom of the radiator, whereby the air flows through a filter at the bottom, then to the fan and finally to the top front of the radiator, - an inlet water distributor at the upper side of the radiator with valve and inlet water temperature sensor, - an air distributor with motor above this inlet water distributor, - a control board with a control panel and - a frame with covers.

The originality of the proposed device is supported by the fact that it is portable, and is characterized by the use of the linear and angular acceleration sensors, to help the worshiper control the prayer pillars and prevent him/her from making errors during the prayer. The principle aim of this device is to help the worshiper to complete performing the prayer pillars and increase his/her self-confidence by performing these pillars correctly. This is achievable by emitting sensory (vibrator) and visually (colored LEDs) and auditory (sound) alarms that can be used individually or combined as a response to the worshiper movements while he/she is performing the prayer. The device can alarm the worshiper to do a certain pillar or warn him/her that an error has occurred in performing a certain pillar, in a way convenient to all worshipers, including those with special needs or partial or permanent disabilities.

A system for generating power by harnessing high altitude wind consists of a flying frame, a generator mounted on the ground and a group of ropes (A, B, C, D) connecting frame and generator. The flying frame looks like a kite containing a closed triangle surface at the top followed by an open rectangular frame in which a smaller rectangular closed surface is positioned in such a way, that it can slide within the frame from left to right and vice versa. The sliding surface is pushed up by wind, lifting the side of frame upwards, which momentarily carries the sliding surface, causing in the next phase the sliding surface to slide down to the other side within the frame by gravity. In turn, the side of the frame, which is now carrying the sliding surface, is lifted and the other side is lowered. In that state the sliding surface is again sliding from the upper to the lower position within the frame. This alternating movement of the frame is transferred to the generator by ropes C and D. Ropes A and B stabilize the frame. A ballon constantly keeps the frame up in the air.

We put the pins in the gypsum cast in the same places and directions which are expected to be planted (fig 11 ). We make the acrylic radiographic method on it. The set is put in the Mouth (fig 14) and section filmed 3D. The photo is studied by computer through Ezimplant-Dental3D program. We modify the entrances and axises if necessary and take the dimensions and film the result by the printer (fig 15, 16) The entrances and axises of the implant are modified in accordance with the study. We decide the new place on the gypsum cast (fig 17). We drill the place of the new implants on the same old Gypsum by using "Dr. lmad Haidar" apparatus after putting the conductor in the place of the old pin (fig 22) to connect the information, and making the surgical director, (fig 28)

An appliance for combined functional and active orthodontic treatment of skeletal class II malocclusion is designed. It consists of affixed orthodontic upper molar bands and two 1 mm diameter stainless steel wires inserted into headgear tubes. Each of them is attached anteriorly to Hp bumper separately. The two lip bumpers are positioned into the lower labial vestibule.

The invention concerns a simple gearbox ratio, designed as a little additional gearbox or as a normal gearbox, when added to a vehicle the gearbox multiplier ratio, when added to a vehicle the gearbox multiplier ratio, in case of providing (5) gear box ratios and (3) internal cone gears the vehicle will comprise (3) multiplied by (5) equal (15) ratios, instead of the original (5) ratios. That will save more fuel, extend the engine life, reduce noise and environment pollution, especially when there are large varieties in vehicle loading, and big differences in road heeling from up or down. If the gearbox multiplier ratio is equipped with a flexible gear, so there is no need to press the clutch paddle while changing the gearbox multiplier ratio. It can be used in all kinds of gear boxes what ever it is automatic or stick shift gear boxes.
