摘要:
The invention is directed to a motor-powered appliance 10 for personal use as, for example, an appliance for oral or dental hygiene, a shaver or the like, with a housing 12 for accommodating the drive means 20 as well as at least one rechargeable energy-storage cell 18. The housing 12 is composed of at least two housing sections 13, 14 sealingly connectible with each other. The appliance 10 has an associated case structure 22 incorporating in particular means 24 for charging the energy-storage cells 18, or in particular means 26 for the storage of attachments for the appliance 10. The case structure 22 includes two abutment means which, in forming an integral part of the case structure 22, provide a tool for severing the housing sections 13, 14.

A scraper-chain conveyor channel section comprises a pair of side walls and a floor plate extending between the side walls and connecting the side walls together. Each of the side walls has upper, lower and intermediate inwardly-extending flanges. The floor plate is connected to the intermediate flanges of the two side walls. Each of the side walls is constituted by an upper profiled bar and a lower profiled bar, each of the profiled bars being a generally U-shaped rolled section. Each of the lower profiled bars has a bottom flange and a top flange parallel to the bottom flange. The top flange of each lower profiled bar forms a support surface for the associated upper profiled bar, and constitutes part of the intermediate flange of the associated side wall. Each of the side walls is provided with a connecting bar for laterally supporting the associated upper profiled bar. Each of the connecting bars is secured to the exterior of the associated lower profiled bar, and projects upwardly beyond the top flange of that lower profiled bar.

The invention relates to a surgical instrument system, which comprises a hollow shaft as well as a shaft-type instrument that can be inserted into the hollow shaft. To create a surgical instrument system that consists of a hollow shaft and of a medical instrument that can be inserted into the hollow shaft and that is both simple in construction and capable of a range of uses, it is proposed according to the invention that at least one cam that reduces the inside diameter of the hollow shaft should be positioned on the interior of the hollow shaft.

Optical fiber-based distributed communications systems that provide and support both RF communication services and digital data services are disclosed herein. The RF communication services and digital data services can be distributed over optical fiber to client devices, such as remote antenna units for example. In certain embodiments, digital data services can be distributed over optical fiber separate from optical fiber distributing RF communication services. In other embodiments, digital data services can be distributed over common optical fiber with RF communication services. For example, digital data services can be distributed over common optical fiber with RF communication services at different wavelengths through wavelength-division multiplexing (WDM) and/or at different frequencies through frequency-division multiplexing (FDM). Power distributed in the optical fiber-based distributed communications system to provide power to remote antenna units can also be accessed to provide power to digital data service components.
摘要:
A thread catcher for surgical sewing material consisting of a handle, a hollow shaft positioned on the distal side of the handle, and a catching device that is mounted so that it can be slid lengthwise within the hollow shaft by means of a drive element and whose distal end, which can slide out of the distal end of the hollow shaft, is configured as a catcher loop. To create a thread catcher for surgical sewing material that is simple to operate and ensures rapid and secure grasping of the surgical sewing material, it is proposed with the invention that the catcher loop should consist of at least three segments that are distally connected with one another.
摘要:
Optical fiber-based wireless systems and related components and methods are disclosed. The systems support radio frequency (RF) communications with clients over optical fiber, including Radio-over-Fiber (RoF) communications. The systems may be provided as part of an indoor distributed antenna system (IDAS) to provide wireless communication services to clients inside a building or other facility. The communications can be distributed between a head end unit (HEU) that receives carrier signals from one or more service or carrier providers and converts the signals to RoF signals for distribution over optical fibers to end points, which may be remote antenna units (RAUs). A microprocessor-based control system or systems may also be employed. The control systems may include one or more microprocessors or microcontrollers in one or more of the components of the system that execute software instructions to control the various components and provide various features for the optical fiber-based distributed antenna systems.
