摘要： An apparatus for cutting concrete is provided and includes a frame having a plurality of support wheels located thereon. A prime mover assembly is connected to the frame, and a concrete cutting blade is drivingly connected to the prime mover. The blade is mounted for generally upward and downward movement relative to the frame for engaging and disengaging from a surface to be cut. A carriage having an anti-spalling roller mounted thereon is connected to the frame such that the carriage positions a surface contact portion of the anti-spalling roller in alignment with a blade exit location for an operative range of cutting depths.

摘要： An air driven dental handpiece having an air turbine at one end thereof. Collet means for securing a dental bur therein are positioned within the air turbine. The air turbine is mounted in ball bearings, which are in turn resiliently mounted within the turbine housing. The handpiece handle is hollow and includes air and water tubes therein. The air and water are mixed within the handpiece at the point of expulsion from the handpiece, thereby creating a coolant mist or fog on the dental bur and the tooth being drilled.

摘要： A self-propelled saw for cutting green or uncured concrete having a frame with rear drive wheels and adjustable front wheels is provided. The saw has a handle for guiding it along the desired path to be cut in the concrete and a drive motor for the saw blade and the rear wheels mounted on the frame. Motor or pump driven means interconnecting the handle and front wheels raise and lower the front wheels at the control of the operator to remove or insert the saw blade into the concrete to be cut. A track assembly, including a pair of parallel tracks moves with the frame as the saw blade is inserted into the concrete and the tracks engage and roll along the surface of the concrete to support the surf ace adjacent the saw blade as the concrete is being cut.
摘要翻译：一种用于切割具有后驱动轮和可调节前轮的框架的绿色或未固化混凝土的自走锯。锯具有用于沿着要在混凝土中切割的所需路径引导的手柄，以及用于锯片的驱动马达和安装在框架上的后轮。将手柄和前轮相互连接的马达或泵驱动装置在操作者的控制下抬起和降低前轮，以将锯片移除或插入待切割的混凝土中。包括一对平行轨道的轨道组件随着锯片插入混凝土而与框架一起移动，并且轨道沿着混凝土表面接合并滚动以在混凝土被切割时支撑邻近锯片的冲浪。

摘要： An irradiation device for directing radiation onto a substance in a desired wavelength range for curing the substance, and particularly for use in curing substances on the teeth of dental patients. A light-emitting lamp assembly is located within a plastic housing of the device, and a heat shield surrounds the lamp assembly to divide the housing into an outer chamber between the shield and housing, and an inner chamber within the shield. The housing includes an entrance conduit for receiving pressurized cooling air, and a channeling arrangement is provided for directing the pressurized cooling air from the entrance conduit, through the outer and inner chambers within the housing, and out of the housing through exit passages.
摘要翻译：一种辐射装置，用于将辐射引导到所需波长范围内的物质，用于固化物质，特别是用于固化牙科患者牙齿上的物质。发光灯组件位于该装置的塑料壳体内，并且隔热罩围绕灯组件以将壳体分隔成屏蔽和壳体之间的外室以及屏蔽内的内室。壳体包括用于接收加压冷却空气的入口管道，并且提供通道装置，用于将加压的冷却空气从入口导管引导通过壳体内的外室和内室，并通过出口通道从壳体出来。

摘要： A dental handpiece having a mechanism for mounting a bur in one end thereof. A fiber optic system is mounted within the handpiece, and is adapted to direct light adjacent the bur when it is rotating to aid a dentist in using the handpiece. The fiber optic system includes a bulb mounted within the handpiece, which bulb is secured in a housing formed from a heat-resistant plastic. Air used for driving the handpiece is also used to cool the heat generated by the light. A pneumatic switch is provided for automatically turning on the light when the handpiece is used and for automatically turning off the light when use of the handpiece is terminated.
摘要翻译：一种具有用于在其一端安装毛刺的机构的牙齿手柄。光纤系统安装在手持件中，并且适于在其旋转时引导邻近毛坯的光以帮助牙医使用手持件。光纤系统包括安装在手持件内的灯泡，该灯泡固定在由耐热塑料形成的壳体中。用于驱动手机的空气也用于冷却由光产生的热量。提供气动开关用于在使用手持件时自动打开灯，并且在终止使用手持件时自动关闭灯。

摘要： An air driven dental handpiece having an air turbine at one end thereof. Collet means for securing a dental bur therein are positioned within the air turbine. The collet means includes a plurality of collapsible jaws at the bottom thereof. Threads are provided on the exterior surface of the collet means in the area of the jaws. The bottom of the collet means is tapered, and a collet nut is threadedly secured on the collet means. The collet nut has an internal taper which is complementary to the taper of the collet means. The threaded advancement of the collet nut on the collet means causes the collapsing of the jaws of the collet means, through the mating tapers, and accordingly a dental bur can be secured in the collet means.
摘要翻译：一种空气驱动的牙齿手柄，其一端具有一个空气涡轮。用于固定其中的牙钻的夹头装置位于空气涡轮机内。夹头装置在其底部包括多个可折叠夹爪。在夹爪区域中的夹头装置的外表面上设有螺纹。夹头装置的底部是锥形的，并且夹头螺母螺纹固定在夹头装置上。夹头螺母具有与夹头装置的锥度互补的内部锥形。夹头螺母在夹头装置上的螺纹前进使得夹头装置的爪的塌陷通过配合锥形，因此牙套可以固定在夹头装置中。
