摘要： A device for spraying a noxious powder includes a housing for a CO.sub.2 cartridge, and a moveable barrel which carries a firing pin by which the cartridge can be punctured to explosively release the gas. The barrel has a nozzle at its outer end, and contains the noxious powder in a chamber defined between the barrel and the firing pin. When the barrel is released from an outwardly extended position it is thrust by a spring against the rupturable end of the cartridge, thereby releasing the gas which in turn propels the active agent through the nozzle and toward the assailant at whom it is aimed. Generally, a powdered tear gas will be employed in the device.

摘要： A torque measuring device is disclosed wherein a torque of a rotating member rotating about an axis is measured. The device includes a support member which is attached to a fixed object such as a stationary frame by at least two linkage arms. Each linkage arm is pivotably attached at a first point of attachment to the fixed object and at a second point of attachment to the support member. The relative positioning of the rotating member, the support member, and the linkage arms is such that geometrical lines interconnecting the respective first and second points of attachment of each linkage arm substantially intersect the axis of the rotating member. The rotating member is in an operative relationship with the support member so that the rotating member during its rotation imparts a force to the support member, which attempts to rotate the support member.An instantaneous center of rotation of the support member coincides with the axis of rotation of the rotating member. A load cell or like force measuring device is interposed between the support member and the fixed object to measure the force imparted to the support member by the rotating member. The load cell and the linkage arms prevent substantial displacement of the support member even though the measured force may vary substantially. From the measured force and a known and constant lever arm of the force the torque of the rotating member is readily calculated.
摘要翻译：公开了一种扭矩测量装置，其中测量围绕轴线旋转的旋转部件的转矩。该装置包括支撑构件，其通过至少两个连杆臂附接到诸如固定框架的固定物体。每个联动臂可在第一连接点处可枢转地连接到固定物体上，并在与支撑构件相连接的第二点处。旋转构件，支撑构件和连接臂的相对定位使得互连每个联动臂的相应第一和第二连接点的几何线基本上与旋转构件的轴线相交。旋转构件与支撑构件处于可操作的关系，使得旋转构件在其旋转期间向支撑构件施加力，这试图使支撑构件旋转。支撑构件的瞬时旋转中心与旋转构件的旋转轴线重合。负载传感器或类似的力测量装置插入在支撑构件和固定物体之间，以测量由旋转构件施加到支撑构件的力。测力传感器和连接臂防止支撑构件的实质位移，即使所测量的力可能显着变化。根据测量的力和力的已知和恒定的杠杆臂，容易地计算旋转构件的扭矩。

摘要： In a network of managed devices, a method of processing network events to reduce the number of events to be displayed in an event log, comprising receiving information relating to network events, passing information regarding a network event to an event processor, determining if the information passed to the event processor relates to a type of event processed by that event processor, and if it is of such a type, processing said information if information on a related event has already been received by that event processor. The method also includes passing said information on to a further event processor if the information received does not relate to a type of event processed by said first event processor.A set of event processors for carrying out the method is described together with a computer program, or a program on a computer readable medium loadable into a digital computer, or embodied in a carrier wave, which computer program operates in accordance with the method.

摘要： A method and apparatus for determining a time interval for periodically polling a device on a network 1 is described. The method determines the most restrictive link on the path to the network device, the level of restrictiveness of a link being dependent on the nature of the link, such as the link speed and link type. The time interval between polling is determined based on the nature of the most restrictive link. Thus, the time interval can be determined according to the type and speed of the links between the polling device, which in a preferred embodiment is a network management station, and the polled device on the network 1.
摘要翻译：描述了一种用于确定用于周期性地轮询网络1上的设备的时间间隔的方法和装置。该方法确定到网络设备的路径上的最严格的链路，链路的限制级别取决于链路的性质，例如链路速度和链路类型。轮询之间的时间间隔是基于限制性最强的链路的性质来确定的。因此，可以根据轮询设备（在优选实施例中为网络管理站）和网络1上的轮询设备之间的链路的类型和速度来确定时间间隔。
