Abstract: A drilling tool for percussive and rotary drilling in advance of a trailing casing tube (20) has a reamer (15) pivotally journalled on an eccentric shaft (12) rearwardly of a centric pilot bit (11). The reamer (15) has an eccentric portion (32) carrying axially directed hard metal button inserts (36-40) grouped within an acute angle (V) of a circle sector centered on the drilling axis (C). The inserts comprise primary inserts (36-38) with a radial reach defining the full diameter of the drilled hole and inner secondary inserts (39, 40) closer to the shaft (12). The reamer (15) is pivotable on the shaft (12) between a projected and a retracted position. When projected, the group of button inserts (36-40) ream up the hole from the diameter drilled by the pilot bit (11) to the full diameter of the hole enabling the casing tube (20) to advance. In the retracted position the drilling tool (10) can pass through the casing tube (20). A duality of inserts (36, 39) leading in the rotational direction act jointly to break the rock in said direction substantially tangentially relative to the shaft (12). The rock cuttings from the button inserts (36-40) are subjected to enhanced flushing action. Optionally such flushing action is further supported by a groove (52) on the rotationally leading flank of the reamer (15). A cutting edge (54) on the groove (52) is reinforced by stellite and improves drilling of claybound ground.

Date Sep. 1, 1994A procedure for moving the main girder (3) and trolley (2) of a crane uses a gantry part (6) with its bracing structures and a traversing machinery with traversing ropes (4), the traversing machinery being mounted in conjunction with the gantry part. According to the procedure, the trolley is moved by the same traversing machinery as the main girder. When the main girder (3) is to be moved, the trolley (2) is interlocked so that it remains immovable with respect to the gantry (6) and the traversing movement is performed by winding one of the traversing ropes (4a or 4b) onto the winding drum (1) of the traversing machinery and at the same time unwinding the traversing rope (4b or 4a) on the opposite side from the winding drum (1). When the trolley (2) is to be moved, the trolley interlock is released and the traversing movement is performed in the manner described above.

Abstract: The invention relates to a process for the disposal of domestic garbage, while recovering oil, carbon black, metals and ceramic (among which vitreous) valuable materials, wherein the domestic garbage is pre-dried and homogenized, by compressing at a pressure of at least 15 MPa while removing the separated water, said garbage subsequently is dried, while also air is driven out and the dry domestic garbage, thus brought in a substantially anaerobic condition is subjected to pyrolysis, and the oil and carbonaceous materials formed in the pyrolysis are recovered and metals and ceramics are separated by classification. Preferably the domestic garbage pre-dried by compression is dried, by exposing it in a space cut off from air supply to electromagnetic waves having a frequency between 300 MHz and 300 GHz, in particular 800-2000 MHz, e.g. in magnetron and/or ionotron ovens.

Abstract: A transmission for a radio pager includes ''label'', ''address'' and ''message'' signals, preferably in that order. The pager stores the label and message signals in buffers (16, 18) and if the appropriate address is detected by a comparator (12), the stored label signal is compared with previously-received label signals stored in a label memory (22). If the label comparison indicates that the message (and associated label) have already been received, and error checking procedures show that errors are present in the received signals, a message combiner (28) pieces together a corrected message signal from appropriate parts of the currently-received and stored message signals, which corrected signal is then stored at the appropriate location in the message memory (24). If the label comparison indicates that the message (and associated label) have not previously been received, the message signal is stored in the message memory (24) and the label signal is stored in a corresponding portion of the label memory (22).

Abstract: A glass block (10) comprises a plurality of intermediate glass plates (12i) stacked between a top plate (12t) and a bottom plate (12b). The top and bottom plate each have a selected composition, with a particular index of refraction and a softening temperature. The intermediate plates have compositions intermediate those of the top and bottom plates and are stacked so as to provide a gradient in composition from top to bottom. Heating the assembly at a fusion temperature fuses the plates together to form the glass block. After cooling down to room temperature, the glass block can be shaped to make lenses and other light directing devices. Such lenses have a gradient in the refractive index of at least about 0.085, and gradients approaching 0.5 are achievable. The thickness of the glass block along the optic axis is fairly unlimited, and thicknesses on the order of 10 mm and more are routinely achievable by the process of the invention.

Abstract: Gaseous components are removed from gas streams and chemically converted into an insoluble phase in a liquid medium. Specifically, hydrogen sulfide is removed from gas streams by oxidation in aqueous chelated iron hydroxide solution in a modified agitated flotation cell. A combined chemical reactor and solid product separation device comprising such modified agitated flotation cell also is described. In order to effect efficient mass transfer and rapid reaction, gas bubbles containing hydrogen sulfide and oxygen are formed by rotating an impeller at a blade tip velocity of at least about 300 in/sec. to achieve the required shear. To assist in the reaction, a surrounding shroud has a plurality of circular openings of equal diameter and arranged in uniform pattern such as to provide a gas flow therethrough less than about 0.02 lb/min/opening in the shroud. Each of the openings has a diameter less than about one inch.

Title: Packaged anti-plaque oral compositions
Inventor: GAFFAR ABDUL
IPC: A61Q11/00
Filed: 1989-12-27
Granted: 2001-02-13
Abstract: An oral composition, such as a paste or gel dentifrice or a liquid mouthwash, containing a substantially water insoluble non-cationic antibacterial agent, such as triclosan, which, when used to clean the teeth or rinse the mouth, acts to decrease plaque on the teeth, is packaged in a dispensing container or bottle which includes a solid polymeric material, such as polyfluoroethylene, which is compatible with the antibacterial agent so that excessive loss of anti-plaque activity of such agent on storage is avoided. Alternatively, various other polymers may be employed as container parts, which normally would cause excessive losses of anti-plaque action of the antibacterial agent in the composition but such action is countered by the presence of a stabilizer, such as a terpene, e.g., limonene, in the oral composition formula. Also described is a method for inhibiting development of plaque on teeth.

Abstract: RECONFIGURABLE SIGNAL PROCESSOR Abstract An interconnection scheme among the processing elements ("PEs") of a multiprocessor computing architecture realizes, through PE reconfiguration, bothfault tolerance and a wide variety of different processing topologies including binary trees and linear systolic arrays. By using a novel variant on a tree expansion scheme, the invention also allows for arbitrary up-sizing of the PE count to build virtually any size of tree network, with each size exhibiting the same high degree of fault tolerance and reconfigurability. The invention may be practiced with 4-port PEs arrayed in a module comprising a 4X4 board-mounted PE lattice. Each PE has four physical ports, which connect to the similar ports of its lattice neighbors. Each PE has an internal capability to be configured to route signals to or from ally of its neighbors. Thus, for tree topologies, any of the four neighbors of a given PE may be selected as the parent of the given PE; and any or all of the remaining three neighboring PEs may be selected as the child(ren) PEs. The PE ports are configured under the control of a remote Host, which establishes an initial desired PE topology. The operability of the PEs is tested, and information on faulty PEs or communications paths is used to enable or disable nodes as necessary by revising the PE port configurations. The nodes thus are reorganized and can run or continue running, on a degraded basis.

The medium also includes myo-inostol in an amount effective to stimulate fungal growth. A blood lysing agent may be used.
