Title: Method for making a mask
Inventor: BAE SANG MAN
IPC: G03F1/68
Filed: 1996-03-22
Abstract: A method for fabricating a light exposure mask comprises forming a pattern (3) on a wafer by use of a primary light exposure mask (2) formed with a light shield film pattern (1) in accordance with a design rule. Data obtained after measuring the size of the pattern on the wafer is then transmitted to a data comparison system by use of a process defect inspection system. The data is compared with the size of the light shield film pattern, thereby detecting a portion of the pattern on the wafer which has a difference from a critical size value of the light shield film pattern. By use of a compensation equation, an amendment value for a portion of the light shield film pattern is determined which corresponds to the detected portion of the pattern on the wafer. Thereafter, a secondary light exposure mask, based on the amendment value, is formed.

Title: Pneumatic suspension for seats
Inventor: GRYP DENNIS J
IPC: B60N2/52
Filed: 1997-02-07
Abstract: A pneumatic seat suspension assembly including upper and lower support members with scissors linkages extending therebetween, a pneumatic spring 25 operatively attached between one set of opposing parallel scissors arms, a height adjuster 30 in communication with the pneumatic spring, a dump valve 60 in communication with the pneumatic spring and a safety rollover valve 70 in communication with the pneumatic spring. The scissors linkage provides the mechanical connection between the seat bottom and the seat support while the pneumatic spring provides the means to raise and lower the seat bottom by use of compressed air which causes the parallel scissors linkages to be pushed upward causing the seat to rise. The height adjuster 30 consists of an air valve connected via air lines to the pneumatic spring and to a valve to transmit or vent pressurized air to or from the spring to allow the seat to be biased vertically within a range while the pressurized air within the air spring compensates for the weight of the seat occupant. The dump valve 60 provides a trigger 64 which, when actuated, releases the air from the pneumatic suspension assembly to lower the seat to its lowest point to allow easy access to the seat such that when re-activated allows for the seat to regain its pre-dump position. The rollover valve 70 is connected along the main air line to the pneumatic spring such that, when the plane of the seat bottom reaches approximately 80{ from the horizontal, the air in the pneumatic spring is released allowing for the seat bottom to descend to its lowest position.

Title: Boiler with temperature controlled bypass in heat exchanger to prevent condensate formation
Inventor: ALBERS AXEL
IPC: F24H9/00
Filed: 1999-04-15
Abstract: In a boiler, a temperature controlled bypass 606 allows a portion 701 of the heated combustion products from the burner (not shown) to bypass the heat exchanger 605 and go straight to the flue, therefore reducing the formation of condensate in the flue. The bypass may be controlled indirectly by a temperature sensor (not shown) or directly by a bimetallic strip 607. If the temperature of the combustion products becomes too low, the bypass gap 606 widens to maintain the temperature of the flue products 705 emanating from the underside of the heat exchanger above the dew point. There may be two temperature controlled bypass gaps (513, 514, Fig 5), one at each side of the heat exchanger. The boiler may have a downwardly firing burner (Fig 4) or an upwardly firing burner (Fig 5).

Title: A fast post-immersion restart system for a marine propulsion unit
Inventor: GLEN ROBERT DUNCAN
IPC: F02B75/02
Filed: 1999-11-04
Abstract: The propulsion unit comprises a piston 5 reciprocating in a cylinder 1 and a combustion chamber 2 with a spark plug 8 and a first drain port 9 which is selectively openable independently of the position of the piston. If the cylinder becomes flooded with water, it can be purged by opening the port 9 and moving the piston 5 so as to expel water through the port 9. Once all the water has been expelled, further movement of the piston causes gases in the cylinder to follow the normal swirl path and pass over the spark plug, thus drying it in situ. The first port 9 may be annular, surrounding the spark plug 8 (fig.2). A second port 10 may be provided to improve drainage. A starting aid can be introduced through the second port 10; once it has started, the engine can be run on a fuel (eg kerosene) less volatile than the design fuel (eg petrol).

Title: Dual electric submergible pumping system
Inventor: SCARSDALE KEVIN T
IPC: E21B43/12
Filed: 1999-12-07
Abstract: A dual submergible pumping system permits the production and/or injection of fluids from or into separate zones 1,2 within a narrowly confined wellbore 24 without commingling of fluids. The system includes at least first and second electric submergible pumping systems 70, 72. Typically, the design allows the electric submergible pumping systems 70, 72 to be arranged generally axially within a wellbore. Each system 70, 72, however, is able to produce or inject fluids along a fluid flow path that is isolated from the fluid flow path of the other electric submergible pumping system 70, 72. Isolation is by packer 124 and plug 112. Fluid from zone 1 is pumped by pump 82 through openings 114 and up the wellbore annulus. Fluid form zone 2 is pumped by pump 84 up pipe 104 and via openings into shroud 92. From the shroud the fluid passes into a pipe via openings 96.
