Title: Biosorbents and process for producing the same
Inventor: CAMACHO JUAN
IPC: C08B5/00
Filed: 1998-11-27
Abstract: A process is disclosed for producing biosorbents by phosphorylation of cellulose-containing materials with phosphoric acid or ammonium phosphate in the presence of urea. Also disclosed are biosorbents with particular good use properties. Biosorbents of this type are used, in particular, for removing heavy metals from aqueous solutions. Proceeding from the disadvantages of the known prior art, purification costs of resultant raw products should be lowered and the formation of unwanted soluble organic polymer phosphates as byproducts should be prevented. The biosorbents should have an improved mechanical strength and very good use properties. The disclosed biosorbents contain 5-10 % phosphorus and 1-4 % nitrogen in the form of carbamide groups. The synthesis mixture is mixed with elementary sulphur before starting the reaction in order to produce biosorbents with an increased mechanical strength. The proposed procedure allows reducing the otherwise customary reaction temperatures by about 40 ~C.

Title: Ink cartridge and printer using the same
Inventor: SHINADA SATOSHI
IPC: B41J2/165
Filed: 1999-11-02
Abstract: In an ink jet printer of the present invention, in order to reduce the manufacturing cost, an inexpensive EEPROM  enabling only sequential accesses is applied for storage elements incorporated in a black ink cartridge and a color ink cartridge. The data array of a memory cell included in each of the storage elements mounted on the ink cartridges is determined in such a manner that a second storage area, in which rewritable data, for example, data on remaining quantities of inks in the ink cartridge, are stored, is accessed prior to a first storage area, in which read only data are stored. This configuration enables the rewritable data to be securely written into the second storage area even after a power-off operation. The second storage area has two memory divisions allocated to each ink, that is, a first ink remaining quantity memory division and a second ink remaining quantity memory division. Latest data on the remaining quantity of each ink is alternately written into these two memory divisions. Alternatively, the latest data on the remaining quantity of each ink is written into these two memory divisions in a duplicated manner. Each ink remaining quantity memory division has a write complete flag to determine whether or not a writing operation has been completed normally in the ink remaining quantity memory division. This arrangement enables the remaining quantities of the respective inks to be monitored accurately and continuously.

Inventor: TURNER DAVID CURTIS
IPC: H01H71/62
Filed: 2000-09-08
Abstract: This invention provides a residual current detector comprising a trip circuit; a magnetic lock assembly including a solenoid that operates in response to a signal from the trip circuit, causing movement of an operating member, with the magnetic lock further including a reset mechanism for resetting the residual current detector following a trip operation; and means for preventing reset of the magnetic lock by restraining movement of the solenoid when the trip circuit is disabled. In the preferred embodiment, a plunger assembly is mounted adjacent to the solenoid of the magnetic lock assembly and fusible link is connected in series with the trip circuit and mounted to prevent movement of a plunger in the plunger assembly. When the trip circuit is subjected to excessive current, the fusible link will melt, thereby permitting the plunger to interfere with movement of the armature of the solenoid. This prevents rest of the magnetic lock assembly.

Title: Profiled surface used as an abradable in flow machines
Inventor: MULLER EDUARD
IPC: F01D11/02
Filed: 2000-11-27
Abstract: The profiled surface is used as an abradable (1) in flow machines. In these machines blade tips (2) move over the profiled abradable in a predetermined direction (v). In so doing they produce a partial surface, an abraded surface (10), which is formed by material ablation. The profiling of the surface is formed by ribs (15) which surround chamber-like depressions (11). A rib direction can in each case be associated with the ribs. The abradable (1) forms a pattern which is built up of strip-like elements (5) and the elements of which lie in the directions of the ribs on connection lines (45) between corner points (41, 42; 43, 44) of a reference grid (40). Largely at each location of the abraded surface (10) - i.e. at least at more than 80 - 95% of the abraded surface - the rib direction differs from the direction of movement (v) of the blade tips (2).   For at least two thirds of the abraded surface the direction of movement deviates from the rib direction by more than 30°, preferably more than 45°. The strip-like elements (5) of the abraded surface can be curved as well as discrete and/or partly connected strips.
