An injection retention plug is insertable into a hole in the outer bark layer of a tree so that upon injection of fluid through the plug to an area between the xylem and inner bark layers, the plug will fill the hole to block leakage of the injected fluid outwardly through the outer bark. The plug is of a size and shape to fill the cross-sectional area of the preformed hole in the outer bark. It includes a core of resilient material which is expandable upon withdrawal of the fluid injection devi...

A method of deflowering a sweet gum tree by injecting a solution containing indolebutyric acid into vascular tissue of the tree is disclosed for preventing undesirable seed and fruit debris.

An improved method of applying a chemical treatment agent to a wood structure characterized by the conventional steps of forming a hole in a wood object, and inserting a container enclosing the treatment agent into the hole. The improvement comprises sealing the container with a suitable closure means fabricated out of a material which undergoes an interaction with the chemical treatment agent or its vapors. When the sealed container carrying the chemical treatment agent is inserted within the p...

A vacuum infusion system and method provides for the introduction of desired chemical or treatment fluid directly into functional water conducting elements of a tree without the introduction of air and the subsequent embolization and dysfunction of part of the trees normal transpirational stream. With the present system and method, an orificed-needle is passed through a previously evacuated chamber containing a liquid medium which has been degassed. The insertion of the orificed-needle through t...

A watch movement comprising an alarm mechanism provided with a vibrating membrane located above the bottom plate, characterized in that the vibrating membrane is an annular plate resting on a supporting ring which is fastened to the bottom plate and pressing against the dial.

A watch with an electronic buzzer which comprises a double-constructed back cover including an inner back cover on which a piezoelectric element is mounted to produce a mechanical buzz sound when a voltage is applied thereto and an outer back cover provided with a plurality of small holes for enhancing transmission of the buzz. A driving circuit for actuating or energizing the piezoelectric element is disposed in the watch case releasably from the back cover and the piezoelectric element. This c...

An electronic wrist watch with an alarm has a buzzer provided on the outside of a watch case, a perforated cover which covers said buzzer, an excitation circuit which drives said buzzer, apparatus for operating the excitation circuit at some predetermined time, and a small-size dry cell battery for supplying the oscillating power of said buzzer. The cover is coextensive with the watch case. An adjustment for controlling the buzzer volume is provided in one embodiment.

A buzzer for a watch has an electromagnet system attached to a support arm, one end of which can be fixed in the watch and the other, free end of which can be adjusted relative to a membrane with a first adjusting element which is in a contacting relationship with the watch. The buzzer has a tongue, clamped tightly on one side, which can be excited to oscillate by the electromagnet system and which strikes against the membrane either directly or indirectly. The location of the tongue relative to...

A small alarm timepiece having a timepiece movement, an electrically operating buzzer as an acoustic alarm signal delivery means, a battery detachably mounted on the timepiece movement for energizing said buzzer for its operation, and an alarm switch for on-off control of the operation of the buzzer. This alarm switch is operatively connected with the movement so as to be closed at a preset time point and to remain closed for a certain predetermined operation period. The drive circuit for the bu...
