摘要： In a safety razor the blade is retained in a manner to permit limited movement relative to the handle in the direction of its longitudinal axis. This is accomplished with blade elements of the type comprising a blade mounted in a cartridge by retaining the blade cartridge in its receptor for movement relative to the receptor. In other embodiments, the receptor is mounted on the handle in a manner to permit limited movement of the handle in the direction of the longitudinal axis of the receptor. The latter embodiment may be employed with any safety razor having its handle positioned in angular relationship to the receptor. To enhance the relative sliding movement, a lubricant may be applied between the moving parts.
摘要翻译：在安全剃刀中，刀片被保持为允许相对于手柄在其纵向轴线的方向上有限的运动。这是通过将叶片盒保持在其接收器中以相对于接受器移动的类型的刀片元件来实现的。在其他实施例中，接收器以允许手柄在受体的纵向轴线的方向上有限的移动的方式安装在手柄上。后一个实施例可以与其手柄定位成与受体成角度关系的任何安全剃刀一起使用。为了增强相对滑动运动，可以在运动部件之间施加润滑剂。

摘要： Abstract for filtering drinking water which includes a lower non-porous container to receive the filtrate. An upper filter vessel closed at its lower end by a high density ceramic filter is stacked in nested relationship to the lower container. When water containing contaminants and pollutants is poured into the filter vessel, it drips through the ceramic filter under gravitational forces and is stored in the lower receptacle.

摘要： An inner tubular assembly positioned in telescoping arrangement with an outer tubular protective assembly forms a chamber for a fluid receptacle in a hypodermic syringe; it supports a hypodermic needle and a piston plunger to inject fluid from or draw fluid into the receptacle. Biasing means acting between the inner and outer assemblies urge the inner assembly including the outer end of the needle to a retracted position. Levers in the form of finger pieces are pivotally mounted on the outer assembly; the levers are biased to urge the lugs formed at their ends through apertures in the outer assembly and into engagement with a shoulder at the lower end of the inner assembly to latch it in retracted position. When the finger pieces are grasped to use the syringe the latch is actuated to released position. Other lugs at the upper portion of the finger pieces aaaare engageable with a shoulder on the upper portion of the inner tubular assembly to retain the needle in exposed position ready for injection.

摘要： A selectively usable particle collector for recovering precious metals in clean condition during use of dental suction apparatus is shown. A reservoir where particles are deposited has a closure cap with ports to one of which can be removably attached a replaceable pick up tube to be inserted in the patient's mouth; the other is adapted to removably receive a flexible hose leading to a vacuum source both ports being in communication with the reservoir. In another embodiment a portion of the cap can be rotated to selectively effect either direct communication from the pick up tube to the flexible hose or through the reservoir. A metering vent is provided to regulate vacuum pressure.

摘要： Sensing devices responsive to changes in the physical condition of the area in which they are located are disposed in elongate, flexible carriers to form a detecting unit which can be arranged in a tortuous, undulating array to cover an undefined area of any shape desired with a detecting density of any chosen value. The detecting unit can assume various forms including that of a pair of conducting elements disposed within an insulating tube in opposed relation positioned to complete the continuity of a switching circuit when the tube is flexed to cause engagement of the conductors. Another embodiment comprises a plurality of braided strands of insulating material extending lengthwise within an insulating carrier cable sheath. A pair of conductors is included in the braiding in a spiral disposition with each conductor being disposed along the entire length in opposed relation to the other conductor. Another embodiment includes a closed tubular element filled with an inelastic fluid having a servomechanism at one end to actuate a switching device for an electric alarm circuit in response to a change in liquid level. A modification of this embodiment would include a light responsive element in lieu of a servomechanism of a sensitivity so as to respond to a change in light transmission due to the interference of the liquid when the liquid level moves to a position which interferes with the light transmission source or the ambient light.
