Abstract: A security lock having a main locking bolt connected to a U-shaped tail member slidably mounted in a housing secured to the door. The U-shaped tail member has an upper branch engaged by a turnable driving arm for movement between a retracted unlocked position for the main bolt and an extended locked position therefor. A spring biasses the driving arm to move the U-shaped tail member to the extended locked position. A key cylinder and an interior handle are connected to the driving arm to turn the arm and unlock the bolt. A spring-loaded latch is biassed to engage the lower branch of the U-shaped tail member in the retracted unlocked position. In the closed position of the door, the latch releases the U-shaped tail member which, under the action of the spring, drives the main bolt to its locked position. The latch can be operated when the door is open to release the U-shaped tail member so the main bolt extends from the lock.

Abstract: A device for supporting a dental prosthesis and to provide a rigid engagement to a dental implant or natural dentition while correcting the lack of parallelism of the latter. The device includes an implant abutment that has a spherical portion and an anchorage portion for rigidly mounting to the implant. A tubular engaging assembly supports the prosthesis and includes two ends. At least one of the ends has a diameter that is smaller than the diameter of the spherical portion and sufficiently large to house a substantial area of the spherical portion. A dental surgeon fills the tubular engaging assembly with cement and brings it in contact with the spherical portion. A protuberance with irregularities for enhancing the engagement is introduced in side the tubular engaging assembly. The latter can be positioned in site to correct any lack of parallelism of the implant.

Abstract: A pet food bowl that includes a protection against small crawling insects to prevent the latter from reaching the food contained therein. The bowl has a container assembly and a protective removable annular cover that can be readily mounted over the water channel formed in said bowl. The design is particularly helpful for cleaning the bowl and having access to all of its parts. The lower peripheral wall extends outwardly at an angle to improve the structural stability of the bowl and preventing accidentally tipping it over. The cover includes a slanted wall that matches the inclination of the upper wall so that it can be aligned and frictionally locked in place, if needed. The water channel that prevents the small insects from crossing to the area where the food is has sufficiently large dimensions to prevent the average insect from reaching it. The opening between the cover and the channel is sufficiently small to prevent the pet from drinking the water.
