Title: Transport of crude oil in cold regions - after dispersion in an aqs salt soln
IPC: F17D1/16
Filed: 1972-10-20
Abstract: In a process for transporting crude oil through pipelines in cold regions, esp. permafrost regions, the oil is dispersed in an aqs. salt soln. (pref. sea water) and pumped through the pipeline at -10 to +10 degrees C. Before transport, the oil is pref. sepd. into a light fraction (which can be pumped at temps. above -10 degrees C), a heavy fraction (which is dispersed as above), and a fraction for local use. The dispersion has a low viscosity and can be pumped at faster rates than the crude oil itself.

Title: Gravity settling tank for separating impurities from fluids - has horizontal perforated separator plates between vertical inlet and outlet plates
IPC: B01D21/00
Filed: 1976-06-22
Abstract: An installation for sepg. impurities from a fluid in a tank or container has, in sequence, a feed pipe for the fluid to be clarified, an inlet zone and a sepg. zone. In the sepg. zone there is a number of parallel plates forming a separator, and this is followed by an outlet zone and a drain. The inlet zone has >=1 vertical plate with openings whilst the plates in the separator are arranged horizontally. In the outlet zone vertical perforated plates cause the flow of the clarified liquid from the separator to converge. All the separator plates are perforated and the perforations are pref. offset to each other with the diameter of the holes in the upper plates smaller than those below. Alternatively, the perforations in the separator plates are not offset and the diameters of all the openings are alike. The plates of the separator may be formed by laminated gauzes. In the inlet zone the vertical plates have their perforations offset to each other and they are arranged so that a strongly divergent flow pattern is set up. Efficient sepn. of impurities is achieved and the plant is as compact as possible. Uniform speeds of flow in the various compartments are assured, and the slow flow carrying oil and sediment from one compartment to another favourably influences flocculation and coalescence processes.

IPC: G01P13/02
Filed: 1982-05-14
Abstract: The indicator consists of a star-shaped rotor (1) and a stationary sleeve (2). The rotor has a number of radial vanes (4) on a horizontal shaft (3). One rotor vane (8) is painted a different colour from the others so that the direction of rotation can be observed.

Patent NL-8600449-A (NL)
IPC: B32B7/00
Filed: 1986-02-22
Abstract: The preferred embodiment of the armour plate composite according to the invention is composed of four main components, viz. the ceramic impact layer, the sub-layer laminate, the supporting element and the backing layer. The ceramic impact layer is excellently suitable for blunting the tip of a projectile. The sub-layer laminate of metal sheets alternating with fabrics im­pregnated with a viscoelastic synthetic material is perfectly suitable to absorb the kinetic energy of the projectile by plastic deformation, sufficient allowance for said plastic deformation being provided by the supporting honeycomb shaped layer. The backing layer away from the impact side and consisting of a pack of impregnated fabrics still offers additional protec­tion. The optimum combination of said four main components gives a high degree of protection of the resulting armour plate at a limited weight per unit of surface area.

Title: The invention relates to a reactor vessel for the purpose of maintaining, enlarging and making commercial use of a small black hole (or ball lightning)
IPC: H02N11/00
Filed: 1992-02-14
Abstract: The invention relates to a reactor vessel for the purpose of maintaining, enlarging and making commercial use of a small black hole (or ball lightning). Proof of the existence of black holes, and studies of their properties, have been provided and described by Stephen Hawking, inter alia in his book "The Universe" (1988) ISBN 9035110064, and by John Boslaugh's book titled "Stephen Hawking's Universe" (1990) ISBN 903510885x. An important phenomenon associated with so-called miniature black holes is Hawking radiation. This radiation consists, inter alia, of an outwardly directed flux of electrons and an inwardly directed flux of antiparticles, the positrons, and also of gamma and X-ray radiation arising from the annihilation of the two particles, when they come into contact with one another. Hawking has calculated that a miniature black hole having a mass of a milliard tonnes will have a core diameter equal to that of a proton, 10-13cm, and an electrical power of 6000 megawatts. (See ISBN 903510885x, p.75). The purpose of the reactor vessel is to exploit the electrical power produced outside the observation horizon of the black hole by conducting the electron flux on the one hand and the positron flux on the other hand in such a way that an inexhaustible D.C. energy can be obtained and utilized. At the same time, by asymmetrically positioning a heavy mass outside the vessel it is possible to generate a mechanical perpetuum mobile. This reactor vessel, not requiring external energy, may be of great use as a generator of electrical energy, as a motor and even as a heat source.

Inventor: LEERKES FREDERIKUS HENDRIKUS
IPC: H04L12/56
Filed: 1994-11-25
Abstract: A transmission system for the transmission of data cells between local stations and a central station. Cell arrivals are registered in a local register (CAR). Those registrations are periodically transmitted to the central station. The central station thereafter transmits the permit codes to the various local stations, in order to transmit the data cells which are most ready. In each local station the data cell which is most ready for transmission is transferred from a cell arrival buffer (CAB) to a cell departure buffer (CDB) as long as the permit code expected for said station, on the basis of the number of time slots since the cell arrival, remains forthcoming. The data cell remains in said buffer as long as no permit code addressed to said station is received. The data cell is transmitted as yet after the reception of a permit code addressed to said station. The data cell is discarded, however, as soon as an empty (unaddressed) permit code is received while the data cell still resides in the buffer. All this has the effect that transmission errors do not permanently frustrate the system. <IMAGE>
