Granted: 1985-08-07
Abstract: In the manufacture of fuel gas or synthesis gas by partially combusting carbonaceous fuel, preferably solid carbonaceous fuel having a high content of non-combustible constituents, finely divided fuel is injected into a shaft-like reactor chamber (10) and is combusted partially while moving down through the reactor chamber, to form a fuel gas or synthesis gas which is removed from the reactor chamber at the upper part (12) thereof, while simultaneously melting non-combustible constituents of the fuel, the resultant melt being taken out of the reactor chamber at the bottom part (13) thereof. A layer (32) of molten material which covers the wall (11) of the reactor chamber and moves downwardly along the wall is sustained by maintaining a selected temperature for substantially instantaneous melting of the non-combustible constituents of the fuel, and by selecting the directions in which the fuel is injected into the reactor chamber so that at least a substantial part of the fuel or the non-combustible constituents contained therein is brought into contact with the wall (11) of the reactor chamber or the layer (32) on said wall during movement down through the shaft. The wall of the reactor chamber is kept cooled in order to maintain thereon, between the wall and the molten layer (32), a frozen coating (33) formed by the non-combustible constituents of the fuel and protecting against slag attack and overheating.

Granted: 1987-03-11
Abstract: For a controlled positioning of a read element relative to a track to be read during the read-out of such a record carrier, low-frequency tracking signals may be recorded in the tracks. Instead of adding separate tracking signals to the information signal, these tracking signals are represented by the d.c. content of the information signal. During conversion of the information words of the information signal into channel words steps are therefore taken to provide two channel words whose d.c. content is equal but opposite for each information word. The choice between these two channel words is made depending on a control signal which depends on the desired tracking signal.

Abstract: The invention relates to the manufacture of furniture by bending cardboard or comparable materials. The aim of the invention is to obtain a cupboard, dresser or piece of furniture of the same kind from a small number, for example two, of precut blanks provided with folding lines. The blanks may be transported in a flat position and assembled on site, the piece of furniture being then dismountable so as to transport it again to another place. A first blank is used to obtain the front face (1), the sides (10), the bottom (2) and the front part (6) of the upper face. A second blank is interconnected in the first blank to form the back face and the remaining part (22) of the upper face. Notches insertable into each other provide for the rigidity of the assembly.

Granted: 1988-02-03
Abstract: A rotary actuator having a cylindrical housing (10) in which an annular piston (40, 58) rotates through an arc within an annular chamber (14) in the housing (10) as a result of fluid pressure to produce rotary motion communicated from the piston (40, 58) to the drive shaft (16). The piston head (58) is capable of lateral or radial movement relative to the piston arm (40) so as to accommodate flexing of the piston arm (40) or variances in the shape of the chamber (14). Friction reduction washers (80, 82) are placed between the piston head (58) and the piston arm (40) to facilitate this movement. The overall effect is to reduce the friction encountered by the piston head (58) against the walls of the chamber (14) during movement, thereby improving overall performance of the actuator.

Granted: 1989-12-27
Abstract: The invention pertains to a method of continuous compensation of unbalance present in a rotor, in particular, a grinding wheel. This is done by feeding a compensation fluid into correction chambers which are rotated with and arranged on the rotor at various angular locations. The supply of fluid is effected in successive balancing operations during rotation of the rotor and as a function of the minimum and maximum unbalance signals measured by a transducer over a certain period of time. The tolerance is determined for acceptable unbalance values. The balancing operation is terminated on the basis of the minimum and maximum which is multiplied by a multiplier determined as a function of allowable variations of the measured unbalance signal.

Abstract: A cashier's safe for banks is disclosed in which money cassettes in vertical columns are held in storage spaces on rotatable racks disposed on opposite sides of the vertical traveling path of a cassette carrier. Each cassette selectively can be brought up to a money receiving and withdrawal point at the top of the safe and returned to its proper storage space by the cassette carrier. Cassettes containing larger sums of money are moved more slowly to the withdrawal point than those containing lesser sums to reduce the probability of robbery. Storage units in the safe for bank notes include bank note storage belts wound on storage drums. The storage units are located on opposite sides of a vertical covered belt conveyor for bank notes which transfer them from the storage units to a bank note receiving and withdrawal point at the top of the safe. Bank note switches associated with the storage units are provided along the covered belt conveyor. The cashier's safe may be automated and a microprocessor may be employed to control the receiving or issuance of money in specified denominations and amounts.

Abstract: A variable dilution cigarette (40), of the type having a filter (42) with two relatively rotatable segments (44,45) having slits (62,63), (60,61) in the plug wrapping (52) and the tipping paper (43) which rotate in and out of rotational registry to vary the dilution level, is provided which is insensitive to slight longitudinal misalignment of the slits. An array of longitudinal depressions (50) is formed in one segment of the filter plug centered on the slit in the plug wrapping and ending short of both ends of the filter segment containing the slit. The depressions act as a plenum allowing the longitudinal flow of air between the slit in the tipping paper and the slit in the plug wrapping in case of longitudinal misalignment arising during use, but do not allow circumferential air flow when the slits are intentionally deregistered by relative rotation of the filter segments. Because the depressions do not reach the ends of the filter segment containing the slit, they do not allow any unwanted air into the filter.
