Patent number: 11957529Abstract: The endodontic point containing ultrasonic deformable material is a filler for root canal therapy that decreases in viscosity when subjected to ultrasonic waves. Once the point is inserted into a prepared tooth space, such as a prepared and cleaned root canal, the point is subjected to ultrasonic waves. The ultrasonic waves cause the viscosity of the point to lower, thus allowing the point to flow into voids in the tooth space and allow air to escape from the voids. The point then hardens and remains in the shape acquired when at low viscosity once application of the ultrasonic waves is stopped.Type: GrantFiled: December 21, 2020Date of Patent: April 16, 2024Assignee: KING SAUD UNIVERSITYInventor: Mohammed Abdullah Alshehri

Publication number: 20220410019Abstract: The amusement ride for children has an open frame and a swinging passenger carriage suspended from a crossbar carried by two trolleys mounted in parallel tracks on the roof of the open frame. The passenger carriage has an upper platform rotatably mounted on a base platform, rotation of the upper platform being controlled manually by the passenger through rotation of a wheel mounted on a column having an end journaled into a bearing mounted in the base platform. A reversible motor is mounted on the roof frame, the shaft of the motor being connected to the crossbar by a crank and connecting rod to control translational movement of the trolleys, causing the passenger carriage to swing forward and backward. The combination of translational movement and swinging movement of the carriage with rotational movement of the upper platform provides a uniquely thrilling sensation for a child seated on the passenger carriage.Type: ApplicationFiled: June 29, 2021Publication date: December 29, 2022Inventors: ABDULLAH MOHAMMED ABDULLAH, ASMAA SAAD ALENEZI, AMEENAH MOHAMMED ALAWADHI, MUNIRA ABDULLAH ALGHANNAM, SHAIKHA KHALED ALMASOUD

Patent number: 10894888Abstract: The invention provides a dust repellant and anti-reflective inorganic coating and the method for preparing the coating. The dust repellant and anti-reflective inorganic coating includes nano-porous silica (SiO2) network of about 5 nm to about 35 nm and is characterized by cracks. The method of preparing the dust repellant and anti-reflective inorganic coating on a substrate includes mixing of aqueous SiO2 solution with a solvent. The aqueous SiO2 solution with the solvent is stirred to form a solution. The solution is coated on the substrate to form a film on the surface of the substrate. Thereafter, the film is annealed by heating the film to a temperature of about 500° C. to about 700° C. within a period of about 2 minutes to about 2 hours. Finally, the film is allowed to cool down.Type: GrantFiled: December 1, 2015Date of Patent: January 19, 2021Assignees: KING ABDULAZIZ CITY FOR SCIENCE AND TECHNOLOGY, FRAUNHOFER INSTITUTE FOR SILICATE RESEARCH ISCInventors: Mohammed Abdullah Bahattab, Walther Glaubitt, Mark Mirza, Mohammed I Alhussani

Patent number: 10895136Abstract: A method for reducing condensate in a subsurface formation is disclosed. The method comprises introducing a first reactant and a second reactant into the subsurface formation. The first reactant and the second reactant produce an exothermic reaction that increases temperature and pressure in the subsurface formation to greater than a dew point of the condensate. Increasing the temperature and pressure in the subsurface formation to greater than the dew point of the condensate vaporizes, and thereby reduces, condensate in the subsurface formation.Type: GrantFiled: September 26, 2018Date of Patent: January 19, 2021Assignees: Saudi Arabian Oil Company, King Fahd University of Petroleum and MineralsInventors: Ayman R.
