Title: Vibrating tooth cutter for rock
Inventor: WRULICH H
IPC: E21C35/22
Filed: 1984-03-29
Abstract: For cutting rock by means of cutting head (1) having its bits (24) cooperating over a limited axial shifting stroke (a) with a cylinder-piston-aggregate, for example a valve (18), it is proposed to intermittently subject the cylinder-piston-aggregate to the action of pressurized fluid, thus exposing the bit (24) during its engaging the rock to percussion forces. During the phases lacking any action of pressurized fluid onto the cylinder-piston-aggregate, the bit (24) shall be pushed into its starting position. This embodiment can be realized with both hydraulic and pneumatic cylinder-piston-aggregates, noting that in case of an embodiment having a hydraulic cylinder-piston-aggregate it is preferred to design this cylinder-piston-aggregate as a valve (18) which simultaneously provides the possibility to expel pressurized liquid via a spraying nozzle (32) onto the mine face.

Title: Fabrication of opthalmic lens: monomer passes through gas permeable tube within vacuum degassing chamber
Inventor: ADAMS JONATHAN PATRICK
IPC: B29D11/00
Filed: 1995-03-10
Abstract: A method and apparatus for making an ophthalmic lens pumps monomer into one end of a gas permeable tube along its interior length while a chamber surrounding the gas permeable tube is maintained at a subatmospheric pressure by means of a vacuum pump. Preferably, the gas permeable tube is made of silicon rubber. Static mixers introduce mixing into the flow of the monomer within the tube in order to expose the bulk of the monomer to the gas permeable walls of the tube. Under such conditions in the gas permeable tube, the majority of the dissolved gasses are removed from the monomer and continue to be drawn out of the chamber by the pump connected to the chamber. The degassed monomer is then transferred into a mold where it is polymerized into an ophthalmic lens.
