    Abstract: In ink-jet pens (10) for use with printers and plotters, an elastomeric, back-pressure bladder (12) is employed to ensure a supply of ink (14) to the printhead (16) under substantially constant pressure. Contamination of ink due to solubilization of components in the bladder by the aqueous-based ink is avoided by employing an elastomer composition essentially of a high cross-link density ethylene propylene diene monomer, carbon black as reinforcement, dicumyl peroxide on Kaolin clay as curative, and fully hydrogenated clay filtered mineral oil as plasticizer. Such elastomers are given by the composition range (in parts per hundred):______________________________________ EPDM resin 100 Carbon black 18 to 30 Curative 7.0 to 7.5 Plasticizer 20 to 25. ______________________________________

    Abstract: A positive displacement rotary compressor includes a stator which contains a rotor and has a stator inlet communicating with atmosphere via a first pilot operated valve and a stator outlet connected to a primary lubricant reservoir via a non-return valve and to an auxiliary lubricant reservoir via a second pilot operated valve and one or more lubricant injection orifices arranged to inject oil into the stator and connected to the primary reservoir via a third pilot operated valve and to the secondary reservoir. The compressor also includes a pilot control system responsive, in use, to the compressed air load to which the compressor is subjected and arranged to switch the first and third pilot operated valves from an open position to a closed position and the second pilot operated valve from a closed position to an open position when the compressed air load falls below a predetermined value. The auxiliary lubricant reservoir is always at substantially atmospheric pressure.

    Abstract: A constant motion pipe swivel joint having a greatly improved useful life without leakage of fluid from the joint. The swivel joint includes a plurality of sealing discs rotatably positioned between an outer joint member and an inner joint member. One side of each disc is coated with a material having a low coefficient of friction and the other side of each disc is bonded to a layer of elastomeric material such as rubber. The discs are pressed together by the inner and outer members to provide a seal which prevents leakage of fluid from the joint. The rubber stretches to allow small degrees of rotation of the joint without any slippage of one disc over another, and the surfaces of the discs are free to slip over each other to allow a large amount of rotation of the outer joint member relative to the inner joint member.
