Patent EP-0078259-A4 (EP)
Title: Screw press with continuous slope feed screw.
Inventor: HUNT ARTHUR J
IPC: B30B9/12
Filed: 1981-05-07
Abstract: A screw press for extraction of liquids from solids or semi-solids having a feed screw (22, 24) disposed in a cylindrical cage (41) formed from filter screens (42). The feed screw has a body portion (22) that increases in diameter over the full length of the screw in a linear fashion forming a gradual slope providing a gentle pressing action on the materials being pressed. A variable speed drive (60) is used to optimize the rotational speed of the feed screw for maximum liquid extraction versus material throughput. The cylindrical cage (41) comprises at least one pair of semi-circular sections connected along a lower edge by a set of offset hinges (46) and bolted together along an upper edge. For cleaning of the press or changing of filter screens, the sections open with the offset hinges causing the sections to move downward and outward, completely clear of the feed screw. The screw press is especially suitable for predraining of grape must prior to final pressing, dejuicing fragile fruits such as apples, and dewatering of materials having a high liquid content.

Patent EP-0446324-A4 (EP)
Title: Backlighting apparatus
IPC: G09F13/18
Filed: 1990-08-22
Abstract: Improved backlighting apparatus evenly illuminates positive and negative LCDs under all ambient lighting conditions. Incandescent lamps (301-304) provide light for distribution by a light pipe (101). The bottom of the light pipe (101) is selectively painted white to reflect light to the top of the light pipe (101) while the unpainted areas reflect light internal to the light pipe (101), controlling hot and dim spots. The corners of the light pipe (101) near the lamps (301-304) are dual angled to reflect the light into the center of the display. The burn-out of a lamp (301-304) will not substantially affect the even lighting capabilities of the apparatus.
Patent EP-0477308-A4 (EP)
Title: Discriminating electret radioactivity detector system and method for measuring radon concentration
Inventor: DORFI KURT
IPC: G01T1/178
Filed: 1991-02-22
Abstract: The detector system includes three substantially similar detectors each of which includes an ionization chamber having a pedestal therein mounting a charged electret. Two chambers are completely sealed except for an equalization aperture. The third detector has filtered inlet openings, which permit entry of radon gas, and responds to gamma rays and radon gas. Each detector is a canister including a lid having a round base surrounded by a cylindrical wall. The canister body is a circular base surrounded by a cylindrical wall that nests within the lid with a telescopic fit. A cylindrical pedestal assembly rests on the lid base and concentrically sandwiches the canister body between the pedestal assembly and lid. A press-fit holds these three elements together. The charged electret is mounted on the platform by a retaining collar that holds the electret with a press-fit. By keeping the three units together until the test starts, one of the sealed containers can have the charge on its electret measured at the beginning of the test in order to provide a baseline measurement. At the end of the test, the charges on the other two electrets are measured and provide a gamma ray background measurement at the test site and a combined radon gas/gamma ray measurement. By calculations, an accurate measure of radon concentration at the test site can be obtained.
Patent EP-0477354-A4 (EP)
Title: Electroluminescent phosphors with long life and method for making the same
IPC: H05B33/14
Filed: 1991-04-17
Abstract: A mixture of predominantly zinc sulfide and minor amounts of a copper activator compound and fluxing agents is first-fired at about 1200 DEG C to form particles of a hexagonal crystalline structure. The first-fired mixture is mortared or otherwise mechanically stressed for variable periods of time beyond its maximum brightness stress period. This material is fired a second time at about 750  DEG C and cooled to produce the phosphor powder. A number of electroluminescent test lamps (Fig. 1) were made incorporating the various experimental phosphors (30) and each of the different mortaring times. For each phosphor made, the brightness rose, peaked and decreased as mortaring time increased (35), but the life characteristic remained a positive function of mortaring time for a substantially longer time than did the brightness (36). An excellent combination of brightness and life is obtained by mortaring beyond the time required for maximum brightness.
