摘要： A dental syringe employs a single thumb or finger operated control member mounted on the syringe for regulating the flow of air or water or spray. The single control moves axially and vertically with respect to the syringe. Axial movement either forward or rearward from a rest position, initiates and controls the quantity of flow of air or water. Vertical movement of the control member initiates the flow of both air and water to produce a spray.

摘要： A dental unit has dental instruments carried by individual nests, the nests being selectively movable from a storage position to a readiness position. Each nest is carried to the readiness position in a controlled manner such that the axis of the instrument becomes horizontal and moves downwardly as the instrument approaches the readiness position.

摘要： PCT No. PCT/DE78/00027 Sec. 371 Date June 15, 1979 Sec. 102(e) Date June 11, 1979 PCT Filed Oct. 16, 1978In dental treatment apparatuses with a plurality of instruments which are connected to a supply component across spirally coiled supply lines attached to the apparatus at an upper level, and with a mounting for the instruments disposed at a lower level, it is required that the instruments be able to be removed from and inserted into the mounting comfortably and without mutual disturbance. It is proposed that the supply component is at an upper level, that each supply line has its individual point of attachment to the apparatus in its connection to the supply component and is spirally coiled in its entire length from the supply component at an upper level to the instrument mounted on a lower level, that the coil formed by each supply line from the connection to the supply component to the instrument runs freely suspended in an approximately straight line at a slight angle to the vertical, and that the instruments are suspended, pointing downward, in slots in the instrument mounting by means of molded parts on the end of the supply lines by the instruments or on the instruments themselves.

摘要： In a foot control, two or more pivoted pedals have a common main spring which provides the same resistance to all pedals. A bias arrangement keeps one pedal from falling down if the other pedal is depressed. A bias arrangement may be a horizontal rod associated with each pedal. The rod is spring biased against the pedal at a location below the pivot axis.In a two pedal embodiment both pedals can control a single electrical element. A stud extends from each horizontal rod. The stud normally prevents a spring biased pivoted member from pivoting and actuating the electrical element. When a pedal is depressed, the corresponding rod and stud move to allow the pivoted member to actuate the electric element and a corresponding switch.
摘要翻译：在脚踏控制中，两个或多个枢转踏板具有共同的主弹簧，其对所有踏板提供相同的阻力。如果另一个踏板被压下，偏置装置可使一个踏板落下。偏置装置可以是与每个踏板相关联的水平杆。杆在枢转轴线下方的位置处弹簧偏压到踏板上。在两个踏板实施例中，两个踏板都可以控制单个电气元件。螺柱从每个水平杆延伸。螺柱通常防止弹簧偏压的枢转构件枢转并致动电气元件。当踏板被压下时，相应的杆和螺柱移动以允许枢转构件致动电元件和相应的开关。
