Title: A cleaning apparatus for cleaning a forming wire
Inventor: NEWTON PAUL
IPC: D21F1/32
Filed: 1998-05-15
Abstract: An improved arrangement is provided for cleaning a forming wire of papermaking apparatus of the kind in which paper stock is ejected from a headbox onto a forming wire, the water within the stock being drained through the forming wire to leave a formed web on the moving forming wire for subsequent passage to a press section. Cleaning apparatus according to the invention comprises a shower disposed upstream from the turning roll for spraining a cleaning liquid on the forming wire; a housing disposed between the shower and the turning roll configured to permit a flow of pressurized air therethrough directed against the wire for removing at least part of the cleaning liquid, the housing including an opening that cooperates with the turning roll for substantially sealing the opening against loss of pressurized air. This improved arrangement utilizes the interaction of a housing connected to a source of air pressure and a forming turning roll for the cleaning of the forming wire of a papermaking machine.

Title: Self-aligned methods of fabricating silicon carbide power devices by implantation and lateral diffusions
Inventor: PALMOUR JOHN W
IPC: H01L21/336
Filed: 1999-06-07
Abstract: Silicon carbide power devices are fabricated by implanting p-type dopants into a silicon carbide substrate through an opening in a mask, to form a deep p-type implant. N-type dopants are implanted into the silicon carbide substrates through the same opening in the mask, to form a shallow n-type implant relative to the p-type implant.  Annealing is then performed at temperature and time that is sufficient to laterally diffuse the deep p-type implant to the surface of the silicon carbide substrate surrounding the shallow n-type implant, without vertically diffusing the p-type implant to the surface of the silicon carbide substrate through the shallow n-type implant.  Accordingly, self-aligned shallow and deep implants may be performed by ion implantation, and a well-controlled channel may be formed by the annealing that promotes significant diffusion of the p-type dopant having high diffusivity, while the n-type dopant having low diffusivity remains relatively fixed. Thereby, a p-base may be formed around an n-type source. Lateral and vertical power MOSFETs may be fabricated.

Abstract: This invention comprises the use of the force of atmospheric pressure to provide locomotion of vehicles and to generate electric power.        This is achieved by choosing and axis or direction of atmospheric pressure and by structurally creating an imbalance in the opposite force vectors along the chosen axis or direction and by transferring the imbalance to an object to cause it to move in accordance with Newton's Second Law of Motion.        The concept's purpose is three-fold:   1. To produce economical power to move vehicles and atmospheric turbines to produce electricity.   2. To substantially reduce pollution of the Earth's atmosphere by burning fossil fuels.   3. To substantially reduce global warming caused by the burning of fossil fuels.   4. Tp reduce the dependence of the world's economies on certain fossil fuels in limited supply, such as oil.

Title: Compressor bleeding using an uninterrupted annular slot
Inventor: TREMAINE ERIC
IPC: F04D29/42
Filed: 2000-02-02
Abstract: A structure and a method to form the structure are provided for an impeller bleed passage of a compressor for a gas turbine engine.  The compressor (10) has an impeller assembly (16) which includes an impeller rotor rotatably supported within an annular shroud (30) having an inlet and an outlet. The shroud (30) is made of two separate annular segments (92, 94) which are axially spaced apart. Each of the segments is supported separately and independently in a cantilevered manner, such that a circumferentially continuous, uninterrupted annular slot (96) is formed between the two segments (92, 94) and air passes through the slot without causing a dynamic component to affect the impeller rotor. The width of the slot is adjustable for different engines depending on the requirements of use of a particular engine. The width of the slot is also self-regulating in response to changes in the air pressure within the shroud because of the deformation of the segments. The structure is relatively simple and inexpensive to manufacture.
