Abstract: A water sink system comprises two knobs each turnable to adjust hot water and cold water correspondingly, and means for turning knobs to a predetermined angle so that a water from a mixing device connected with both the knobs flows with a desired temperature, the means including a scale formed as a disc and provided with a plurality of lines with numbers, and a central opening so as to be placed on an outer surface of a sink, and a pointer arranged in a bushing extending through the central opening of the scale and located inside a handle, so that by turning of the handle the pointer is turned relative to the scale.

Abstract: A safety system operable during vehicle accidents comprises a seat located inside a vehicle and having a back, a safety belt assembly operative for holding a user to the seat, and means for connecting the back of the seat to a vehicle roof.

Abstract: A protective jacket, comprises an inner layer and an outer layer composed of an air-impermeable fabric, a layer of a resilient porous material located between the inner and outer layers, and filtering means, the layers being formed so that when the jacket is fitted on a user's chest and upper part of stomach, during inhaling a pressure in an interior increases and air is pressed through the filtering means to be inhaled by the user.

Abstract: A refrigerator comprises a main body having an inner chamber, a door moveable relative to the body between an open and a closed position, the main body having substantially horizontal main shelves, the door having substantially horizontal door shelves formed so that in a closed condition of the refrigerator the door shelves are turned into the main body, the door walls extending radially, the main shelves and the door shelves being provided with vertical walls which cooperate with one another so that the door shelves with the vertical walls.

Abstract: A water sink system, comprising a water discharge member, two rotatable knobs for allowing hot water and cold water to flow into the water discharge member and meet there to produce discharged water with a desired temperature, a scale provided near each of the turnable knobs and having a plurality of graduation marks, and a pointer provided on each of the turnable knobs and turnable with the latter, so that when a user by turning the turnable knobs reaches a desired temperature, each pointer points to a respective graduation mark of each scale, with graduation marks can be memorized by a user and thereafter he can turn the knobs immediately to the memorized graduation marks.

Abstract: In a movable carriage having upright walls the bottom is pivotally connected with the walls and has two bottom portions pivotally connected with one another, so that in a horizontal position the bottom can support goods, in a completely upright position a user can walk inside the carriage, and in a position in which one bottom portion is placed on another bottom portion a seat is formed and a user can sit in the carriage.

Abstract: A loading element is brought into contact with an eyelid of a closed eye under load so that the eyelid produces on a surface of the loading element an imprint with a size which is inversely proportional to eye pressure. Two loading elements formed as cylinders can be provided for producing simultaneously imprints of the eyelids of both eyes, and they can be mounted on a spectacles frame.

Abstract: A firearm has a barrel, elements for displacing carriages, bullets and the like to a next firing position, striking elements for striking the same, actuating elements for actuating said displacing and striking elements and including a bush with a trigger and at least two sights and movable between a first position in which it is located in the region of a forearm of the user so as to be concealed under a sleeve of the latter, and a second position in which it is displaced to a hand of the user so that the user can act upon the trigger and use the sights, whereby for firing only the bush with the trigger and the sights are displaced.

Abstract: A handrail has an immovable base element extending in one direction, a support element arranged to be grasped by a user and reciprocable relative to the base element, and a drive for reciprocating the support element relative to the base element. The base element may be formed by a usual stationary handrail, may be connected to the latter, or may be formed as a plate. A guiding element guides the support element during its reciprocation. The drive includes an electric motor which is reversible, a spindle member provided with a thread and rotatable by the motor, and a nut member translatorily movable by the rotation of the spindle member and connected with the support element so as to move the latter. Switches are provided for reversing the direction of rotation of the electric motor and thereby the direction of movement of the nut member and the support element.

Abstract: A device comprising a conical, inflated bladder to be mounted on the back of a user's leg to aid in the distribution of body weight when the user is in a squating or kneeling position.

Abstract: An arrangement for protecting of organs of respiration has a closing element adapted to close the user's nose and mouth, a filtering element communicating with said closing element so that when the user performs inspiration ambient air passes through said filtering element and is cleaned by the latter to be inspirated in cleaned condition, and a device for urging air to flow to and to pass through the filtering element. The device includes an urging element which is actuated in response to the inspiration performed by the user. The device may be formed as a deformable container which is mounted on the user's thorax so that when the user performs inspiration and the volume of thorax increases, the container is deformed and thereby forcedly urges air to the filtering element. The device may also be formed as an impeller driven by an electric motor which is actuated in response to the user's inspiration.

Abstract: An article of advertisement includes a transparent container, and a plate-like member located in the container and carrying an image of eyes. When the article is mounted on a movable object such as a vehicle, the plate-like member displaces relative to the container since one of the transverse dimensions of the plate-like member is smaller than a respective one of the dimensions of the inner chamber of the container. This provides for impression of moving eyes. The inner chamber of the container may be filled by a transparent liquid so that the plate-like member floats in the inner chamber. Thereby, friction between the walls of the container and the member is eliminated, and the eyes in the liquid have a greater impression of movability and sparkling.
