Abstract: Grape vines may grow on a trellis comprising a series of wires supported by a line of posts, but it is difficult to machine-prune vines after harvest without interference from wires. A trellis having primary posts and secondary posts may support vines in a manner that cane growing from vine's cordons can be readily removed. Between each neighing pair of primary posts there are at least two secondary posts. A cordon wire runs along and is supported by the posts at or adjacent to top. Cordons of vines are connected to, and grow along, wire such that most foliage and grapes forming part of vines grow below wire. Wire is held by posts above ground level in a manner to be non-destructively pulled upwards to free it from posts. This may occur after cordons have been severed from rest of vine and may then be readily stripped from wire.

Abstract: The germ and noise filter device is a disposable, hand held filter apparatus that covers the mouth of the user during the exhale phase of a cough. The device comprises: a body with a cavity that houses three micro-filters; a corrugated tube; two one-way valves and a mesh screen. The body can be made of durable plastic material that may be transparent or a combination of many attractive colors. The two one-way valves act as a filter element for the noise that would normally occur. An eyelet is formed on the body to allow the device to be worn about the person. When a cough is eminent, the opening of the device is engaged against the user lips to prevent the transmission of air-borne diseases and reduce the noise of the coughs.
