摘要： A pneumatically operated secateur provided with a nozzle which emits a spray of protective fluid through the nozzle when the secateur operating trigger is released. The spray is emitted in a metered quantity from a pump when mixed with the escaped air from the secateur. The method involves an operator holding a finger on the trigger until the nozzle has been directed on the wound caused by pruning, and then releasing his finger to spray the wound with protective fluid.
摘要翻译：气动操作的旋塞器设有喷嘴，当释放分离操作触发器时，该喷嘴通过喷嘴喷射保护流体。当与来自分离器的逃逸空气混合时，喷雾从泵中以计量的量排出。该方法包括操作者在扳机上握住手指，直到喷嘴被引导到由修剪引起的伤口上，然后释放他的手指以用保护液喷射伤口。

摘要： A cutting tool has a cutting head, a motor and a transmission means drivable by the motor. The cutting head comprises first and second cutting members, wherein the first cutting member is pivotably moveable with respect to the second cutting member. At least the first cutting member is drivable by the transmission means between a first angular position with respect to the second cutting member and a second angular position with respect to the second cutting member, in which a space between the respective cutting blades is closed. The transmission means is a bevel gear on the output shaft of a gearbox which conveys drive power from the motor to the drive gear. The bevel gear directly engages a bevel wheel member connected to the first cutting member and which swivels with the first cutting member about the same swivel point. A controller comprises main, first and second switches which control the motor to move the first cutting member (movable blade). The main switch acts as a main power switch whereas the first ad second switches act as limit switches detecting movement of said movable blade at the limits of its intended motion. The controller exerts automatic control over movement of the first cutting member in response to inputs from the first and second limit switches.

摘要： In my co-pending application Ser. No. 949,811 of Oct. 10, 1978, now U.S. Pat. No. 4,188,718 I disclosed an improved device for "girdling" trees. That device effectively removes a complete circular band of bark and all that underlies the bark to the central portion of the tree so that fluid cannot pass from the root system of the tree to the upper portion of the tree whereby, with the elimination of such fluid transmission, the tree dies. In many areas, such girdling is practiced widely as a method of improving the ecology of the area for the dead trees are readily removed by being pushed over by a bulldozer. This invention relates to a construction of such a girdling device whereby the bark or other material caught between the cutting element during girdling can be readily removed.
摘要翻译：在我的共同待决申请 1978年10月10日第949,811号，现为美国专利第4,188,718号我披露了一种改进的“环绕”树的装置。该设备有效地去除树皮的完整圆形带，并将树皮的所有底部全部移到树的中央部分，使得流体不能从树的根系传播到树的上部，由此消除这种流体传输，树死了。在许多地方，这种环绕作为一种改善该地区生态环境的方法被广泛地使用，因为这些死树被推土机所推动，容易被除去。本发明涉及一种这种环形装置的结构，其中可以容易地去除在环绕期间捕获在切割元件之间的树皮或其它材料。
