Title: Washbox for separating materials, and a method of separating coal from shale
Inventor: CRAVEN GEOFFREY FRANCIS
IPC: B03B5/24
Filed: 1981-05-15
Granted: 1986-05-22
Abstract: A wash-box for separating materials of different densities (e.g. coal and shale) comprises a stratification compartment (8), a perforate grid plate (12) extending across an upper part of the stratification compartment, and means (20, 22) by which water is admitted to the wash-box. The wash-box comprises a compression chamber (10) in underwater communication with the stratification compartment, and pressure applying means (14, 16, 18, 19) operative alternately to pressurise and de-pressurise the compression chamber (10), to cause repeated rising and falling of movement of water in the stratification compartment, to stratify raw material on the grid plate (12). The wash-box comprises a control device (24), comprising a pressure transducer (26) operative to measure the pressure pertaining in the compression chamber (10), in particular the average pressure pertaining in the compression chamber over a complete cycle of rising and falling movement of the water in the stratification compartment, and to produce a control signal dependent upon such measurement. The control signal is compared with a preset value, and the difference between the control signal and said preset value is utilised to determine the rate of admission of water to the wash-box, by actuation of a valve (22).

Patent DE-3480106-D1 (DE)
Title: Lambda-controlled mixture-measuring system for an internal-combustion engine
Inventor: CLEMENT ALBRECHT DIPL ING
IPC: F02D45/00
Filed: 1984-12-22
Granted: 1989-11-16
Abstract: The invention is directed to a mixture metering arrangement for an internal combustion engine and includes an exhaust-gas sensor which is exposed to the exhaust gas of the internal combustion engine. The exhaust-gas sensor indicates the air ratio lambda and preferably has a two-level characteristic. The sensor output signals are acted upon by a follow-on controller which is preferably a PI-controller. The controller output quantity acts upon the mixture composition in a corrective fashion. In this arrangement, the control oscillation of the controller output quantity is adjusted to a predetermined amplitude by means of a superposed control. In particular, the integral component of the control oscillation is influenced in a manner causing it to have the same amplitude as the proportional component while in the steady operating condition. Thus, it is possible to maintain the maximum control frequency in any operating range of the internal combustion engine so that the controller always operates at its optimum. In addition, the effects of deviations occurring from one engine to another or from one exhaust-gas sensor to another as well as of long-term variations are suppressed.

Title: Process for encapsulating oils containing products which produce a colour by reaction, microcapsules produced by said process and their use in carbon papers
Inventor: PIETSCH GUNTHER
IPC: B01J13/18
Filed: 1985-12-23
Granted: 1988-12-08
Abstract: A process for microencapsulating hydrophobic oils with color reactants, dissolved therein, of color reaction systems by reacting a water-soluble non-ionic melamine/formaldehyde precondensate and a water-soluble polymer in an oil-in-water dispersion for forming the capsule envelope is described. The special feature of this process is that, for stabilizing the oil-in-water dispersion, an aqueous solution of a cationic melamine/formaldehyde precondensate and the aqueous solution of a water-soluble polymer are mixed with vigorous stirring, a solid precipitating as a very fine suspension in the mixture, the mixture thus obtained and containing the very finely suspended solid is mixed with ther oil, containing the color reactant in solution, with vigorous stirring, the oil-in-water dispersion thus obtained in acidified and an aqueous solution of a water-soluble non-ionic melamine/formaldehyde precondensate is added with stirring, in order to form the capsule envelope. The use of the cationic melamine/formaldehyde precondensate leads to the precipitation of a very finely suspended reaction product thereof, whereby all the reaction systems in the course of the process are stabilized. Excellent capsules can be obtained without formation of agglomerates. The invention also relates to the microcapsules obtainable by the above process and to their advantageous use in color reaction recording systems.

Inventor: SWANSON ROY T
IPC: H01H31/00

Granted: 1991-06-27
Abstract: An energy-absorbing element (51) is provided between an insulative piston (52) and a movable contact (28) of a switch (22) for a high-voltage device (12). In arrangements where a fusible element (18) is in electrical shunt with the switch, the energy-absorbing element improves the rapid commutation of the current from the switch to the fusible element where final circuit interruption takes place. The switch is of the general type in which ignition of a power cartridge (32) moves the insulative piston, which is normally located in a bore (30) formed in a conductive member (24), away therefrom and into a passageway (44) formed in an insulative liner (46). The movement of the piston moves the movable contact through the passageway and away from the conductive member to break an electrical interconnection (via 50) between the conductive member and the movable contact. This forms a gap between the conductive member and the movable contact and opens the switch. The ignition of the power cartridge evolves high pressure within a chamber defined by the piston and the bore. This high pressure acts against the piston and the resulting forces rapidly drive the piston; the movable contact being driven via the transmission of forces through the energy-absorbing element. The energy-absorbing element enhances the rapid and simultaneous movement of the piston and the movable contact. The energy-absorbing element absorbs sufficient energy at the interface between the piston and the movable contact to prevent undesirable reaction effects which may be caused by the reaction or rebounding forces between the piston and the movable contact.
