    • A mail box comprising a separated top and bottom port. A pivotally hinged gate/tray serves for depositing the incoming mail. The gate/tray has a pocket for outgoing mail and secures the top port from theft. Under the gate-tray a fixture with short wave ultraviolet (UV) light irradiates the box inside simultaneously generating ozone for a predetermined time. This time starts after the outgoing mail is put in the pocket or the incoming mail is dropped inside. A specially designed basket provides space around the mail where sanitizing gas freely diffuses. The light source can irradiate and activate gas-releasing material generating other disinfecting gas such as chlorine dioxide or ethylene oxide. The bottom port is closed by a locked door and allows for retrieving the mail, and setting and maintaining the UV-fixture. Two signals on an outside flag indicate the beginning and the end of the sanitizing process.
    • 包括分离的顶部和底部端口的邮箱。 铰链式门/托盘用于存放传入邮件。 门/托盘具有用于传出邮件的口袋,并确保顶部端口被盗。 在门托下,具有短波紫外线(UV)光的固定装置照射盒子,同时产生臭氧预定的时间。 这个时间是在外发邮件放在口袋里或者收到的邮件放在里面之后开始的。 专门设计的篮子可以在消毒气体自由扩散的邮件周围提供空间。 光源可以照射和激活产生其它消毒气体的气体释放材料,例如二氧化氯或环氧乙烷。 底部端口被锁定的门关闭,并允许检索邮件,以及设置和维护UV固定装置。 外部标志上的两个信号表示消毒过程的开始和结束。

    • Presented is a flow metering valve that can precisely and accurately regulate the volume of the fluid-flow through entire range of measured flows. The valve comprises tubular body and moving stem in it. One end portion designated as a leading has threadely engaged stem and body. Another portion designated as a regulating has body with the stem extended to fill the tubular space longitudinally separating inlet and outlet ports. At least one of the surfaces—the inner of the body or the outer of the stem—is threaded and have their threads truncated by tapering truncation from the crest to the root. The truncated thread forms channel having cross-section tapering from one port to the other. The axially moving stem gradually changes the cross-section of the channel providing variable flow communication between the two ports. The fluid flow changes proportionally to the cross-section of the formed channel. The valve provides very fine regulation of the flow within four orders of magnitude.
    • 提出了一种流量计量阀,可以精确和精确地调节流过整个测量流量的流体流量。 该阀包括管体和其中的移动杆。 指定为领先的一个端部具有极其接合的杆和身体。 指定为调节的另一部分具有主体,其中杆延伸以纵向分离入口和出口端口填充管状空间。 表面的至少一个 - 主体的内部或者干的外部 - 是螺纹的,并且它们的螺纹通过从顶部到根部的锥形截断被截断。 截头螺纹形成具有从一个端口到另一个端部的横截面渐缩的通道。 轴向移动的杆逐渐改变通道的横截面,从而在两个端口之间提供可变的流动连通。 流体流动与形成的通道的横截面成比例地变化。 该阀提供非常精细的流量调节四个数量级。
