Abstract: A method of knitting an upholstery fabric having at least two adjoined regions of different knitted structures located side-by-side in a wale-wise direction and having courses extending continuously through both regions in which the fabric is knitted with stitches having a first loop length in one region and a second, different loop length in the adjacent region, the loop lengths of the two adjacent regions being relatively adjusted so that, in the relaxed condition of the fabric, the same number of courses in each of the two regions of different knitted structures in the wale-wise direction extend for substantially the same wale-wise distance, so as to give the overall structure a balanced even appearance.
Abstract: A process for protecting a rigid substrate against aquatic fouling comprises coating the substrate with an elastomeric undercoat as a 200 to 1500 micron thick layer and with a top coat of a room temperature vulcanisable silicone rubber. The elastomeric undercoat is generally harder than the room temperature vulcanisable silicone rubber foul resistant top coat and preferably has a Shore A hardness of 60 to 90 and an extensibility of 200 to 800%. The abrasion and tear resistance of the silicone rubber foul resistant layer is markedly increased by the use of the elastomeric undercoat.

Abstract: An actuator cap for a pressurized aerosol dispenser includes an integrally hinged actuator tab secured with tamper proof frangible webs. The webs must be broken and the tab rotated about the hinge to engage the container valve stem. Detents on the tab and cap latch the valve open for continuous discharge.
