Patent NL-7211671-A (NL)
Title: Liquids continuous sterilizer - employing friction heat in high speed disc centrifuge
IPC: A23C3/033
Filed: 1972-08-25
Abstract: In parent patent a liquid is passed through clearances of 0.2 mm. to 0.3 mm. between a centrifuge disc and its casing, the resultant heat of friction and pressure in the casing bringing the liquid to its treatment temp. for a fraction of a second as it passes through. The narrow clearances between disc and casing becomes a problem. Then distortion takes place due to temp. and pressure stresses; this is overcome by permitting limited axial float of the disc relative to the casing, also the disc is made from a nickel-chromemolybdenum steel with 3% copper to obtain a heat-treated disc of high elastic limit.

Title: Coffee aroma compsn. for coffee powder - obtd. from aroma condensate, is added to powder in liq. glyceride
IPC: A23F5/48
Filed: 1975-05-12
Abstract: Prepn. of a substance contng. coffee aroma, which may be added to coffee as a condensate, by introducing a crystalline condensate contng. the aroma in high yield in CO2 into a vessel under press. and contacting, whilst isolated from the atmos., with a liq. glyceride in the ratio of 1 g. of glyceride per 0.5-6 g. to crystalline condensate, and relaxing the press. to recover glyceride contng. the coffee aroma. The press. in the vessel is pref. >=7.2 kg./cm.2 at 32-49 degrees C. The mixt. is pref. kept under press. for >=1 hour. The coffee aroma substance may be added to soluble coffee powder to improve the flavour. The process reduces loss of coffee aroma and uses a smaller amt. of glyceride to incorporate into the coffee grains to achieve the desired degree of aromatisation.

Title: Press for cheese containers compensating different filling levels - has conveyor and pressure distributing plates loaded by bellows
IPC: A01J25/15
Filed: 1976-12-10
Abstract: Cheeses are pressed simultaneously in vessels having a loose cover. Vessels are moved on a conveyor, and pressing elements above the conveyor apply a load to the vessels filled with cheese. Balancing plates distribute the load applied by the pressure sources such as pneumatic bellows, over the covers of a number of the vessels contg. cheese. The machine for pressing the cheeses in vessels the covers of which fit loosely inside them, has a conveyor for supporting and moving the containers through it. The pressing bellows are pref. positioned above the containers and the load is applied through distributing plates balancing out the force applied over the covers of a number of containers. The pressure balancing plates are pref. arranged in parallel. Arrangement ensures application of a pressure corresponding to the degree of filling of the containers. The flanges of the conveyor and the support plate facilitate the collection of whey and cleaning of the machine.
Patent NL-7713807-A (NL)
Title: Liquid storage system - with lighter liquid equalised in level with surrounding denser liquid
IPC: B65D88/76
Filed: 1977-12-13
Abstract: A system for storing two liqs. of different densites includes walls defining a liq.-impervious outer chamber, a flexible liq.-impervious membrane disposed in spaced relation to the walls to define an inner chamber contg. the less dense liq., the more dense liq., filling the space within the chambers, and an arrangement to substantially equalise the levels of the two liqs. by overcoming the density differential between them. The two liqs. may be petroleum and water. The density differential may be overcome by loading the less dense liq. with a solid or solid and liq. mass imposed on its upper surface or with fluid press. The system is environmentally safe owing to the less dense liq. being maintained under more than its vapour press., and may be located in abandoned strip mine areas and/or in areas of high water table. Spreading of the liq.-impervous membrane is avoided, and the liq. of the solid and liq. loading mass may be used for fire fighting and/or expelling the less dense liq. from the system.

Title: Climatic compensator for wind or solar power generation - has shaft journalled at two or more points with flywheels weighted and rotated by electric motor
IPC: F03G7/10
Filed: 1987-09-17
Abstract: The device for generating has a shaft journalled at two or more points having one or more rigidly mounted fly wheels. The flywheel(s) is/are each weighted at two perpendicularly opposing points by equal weights. The shaft and flywheel(s) is/are rotated by an electric motor supplied from the mains.

Patent NL-9301272-A (NL)
IPC: C07K14/01
Filed: 1993-07-20
Abstract: Novel proteins of the Chicken Anemia Virus are described and compositions for preventing or treating infections with that virus (CAV), in particular vaccines less pathogenic than the CAV itself, but yet leading to neutralizing antibodies in the immunized animal. Besides, there are described compositions containing antibodies against parts of the CAV for the control of infections with CAV and anti-idiotype antibodies which possess an immunogenicity corresponding to the antigen. The invention also provides antibodies for the detection of CAV infections and test kits for the detection of CAV. Recombinant DNA molecules derived from CAV coding for an immunogenic part of a CAV protein and host cells transfected with such DNA molecules and vaccines based on these host cells are made possible by this invention. Also, living virus vaccines in which a piece of DNA coding for an immunogenic part of a CAV protein is brought into a virus infectious to the desired host are a subject of the invention. Besides, the invention relates to uses of proteins of CAV in the induction of apoptosis, in particular, the proteins can be used in induction of apoptosis in tumor cells. The invention further provides the induction of cell death by means of gene therapy.

Title: Bolt assembly with a rotating locking bolt head and a floating bolt element for automatic firearms
Inventor: BENELLI PAOLO
IPC: F41A3/00
Filed: 1984-05-08
Abstract: In a bolt assembly for inertial operating automatic firearms using the kinetic recoil energy, of the type comprising a locking bolt head and a floating bolt element with a spring interposed between them, the locking bolt head is a rotatable head having a cylindrical portion (1) and a shank (2) narrowed with respect to the cylindrical portion.The cylindrical portion (1) has two radial crescent shaped diametrically opposite projections (6), (7) adapted to enagge each an associated groove (12), (13) provided in the barrel (9) and to disengage therefrom by passing through two associated recesses (10), (11) having a shape corresponding to that of the two crescent shaped projections (6), (7) of the head.The shank (2) of the locking bolt head is received in a cylindrical bore (21) of the floating bolt element (19) and engages by means of a pin (5) projecting therefrom a helical slot (20) of the floating bolt element (19).interposed between the shank (2) of the rotatable locking bolt head and the floating bolt element (19) is a spring (30).When the arm is locked the projections (6), (7) of the cylindrical portion (1) of the locking bolt head are in the associated grooves (12), (13) of the barrel (9).At firing, at the beginning the floating bolt element (19), because of its reaction to the recoil of the arm, advances and compresses the spring.Immediately after the spring (30) spreads out and causes the floating bolt element (19) to move back which unlocks the rotatable locking bolt head and causes the pin (5) to slide in the helical slot (20) thus disengaging the rotatable locking bolt head from the barrel (9) and causing the projections (6), (7) of the cylindrical portion (1) of the head to pass through the two recesses (10), (11) of the barrel (9).The arm is thus open and reloads itself automatically in a conventional manner.
