Inventor: BYRNE PAUL
IPC: A63B51/10
Filed: 2000-11-14
Abstract: ABSTRACT             String breakage in racquet sports can be attributable in part to the friction between abutting strings that cross at intersection points of the string mesh. A ball contacts the strings numerous times during a game, and the pressure of the ball at the intersection points forces the abutting strings to rub against each other. The compound effect of this friction results in string breakage. A racquet string saver composition and method are disclosed for reducing or delaying string breakage on a racquet. The composition comprises a tackifying agent in combination with an acceptable carrier. The method comprises the step of application of a tackifying agent to racquet strings.

Title: Packets and packaging
Inventor: CAHILL MICHAEL JOHN
IPC: B65D85/808
Filed: 1991-03-20
Abstract: Twin compartment packets, eg. tea bags, are formed with the compartments connected at the heads of the packet and optionally at the tails. The packets are produced from a pair of compartmented tubular webs that are brought together with the compartments in register, the webs then being interconnected at the compartment end seals and severed at those seals to form the separate packets. Apparatus for performing the process deposits doses of tea at spaced intervals onto the two separate webs before forming them into the tubular compartmented webs, brings the compartments of the two webs into register, interconnects the registered compartments, and separates the interconnected compartments into individual packets while the web advances continously through the apparatus. The process is capable of high production rates because the webs are able to move through the successive stages at a uniform speed.
