Title: Hydrocyclone deinking and removal of sticky contaminants during paper recycling
IPC: B04C5/10
Filed: 1991-06-11
Granted: 1993-02-11
Abstract: The removal of sticky contaminants and/or ink particles during the production of recycled paper is accomplished utilizing a hydrocyclone (31) froth flotation process. Paper having sticky contaminants from labels, tapes, hot melts, and other tacky substances, and/or print, is reduced to a finely comminuted liquid solids suspension of about 1-4% consistency (preferably over 2%). The suspension is introduced into a first end (44) of a vortex (41) in a hydrocyclone (31), and the air is sparged radially inwardly into the suspension vortex by passing it through a porous inner wall (47) of the hydrocyclone. Lighter weight sticky contaminants move to the center of the hydrocyclone, facilitated by the radially inward movement of the sparging air, and hydrophobic sticky contaminants and/or ink particles attach to the air bubbles and form a foam. The foam and lightweight sticky contaminants are removed from the first end (at 33, thru 51) of the vortex, while the pulp which has had sticky contaminants and/or ink removed therefrom is discharged from the second end of the vortex (at 32), opposite the first end. A plurality of vertical axis hydrocyclones (21) may be connected together in series, with a plurality of the series connected in parallel, to provide the most effective treatment. Removal of sticky contaminants can be practiced prior to or simultaneously with deinking (Figure 3).   <IMAGE>

Title: Pneumatic drill hammer
Inventor: WALTER HANS-PHILIPP
IPC: E21B4/14
Filed: 1994-12-14
Granted: 1997-05-08
Abstract: In the bottom part, a pneumatic deep-hole hammer (10) has an outer tube (55), a control-housing shell (60) together with non-return valve (59), and a central tube (80) which has radial passages (81, 83) and on which a percussion piston (75) slides. The head of an axially displaceable drill bit (90) can be slipped onto the bottom end (84) of the central tube. A cylinder liner (70) guiding the piston (75) and the control-housing shell (60) are circumferentially welded to the outer tube (55) over an axial area (welding zone S, length l). Sitting above them is an adapter (40) which has top air passages (42), carries a blast ring (50) with nozzles (53) directed upwards, and is connected in a drive-transmitting manner to a sleeve (15) either directly or via a sliding piece (30) with guided shaft (20), which sleeve (15) sits under the connection cap (11). The bottom end (23) of the shaft (20) forms a control slide relative to the adapter top part (41), from which passages (42, 47) lead to a control-housing chamber (62) with passages (63). An annular chamber (68) follows below a tubular body (61) between outer tube (55) and cylinder liner (70). The free cross-section of the annular chamber (68) corresponds to the narrowest central bore (12, 22, 32, 42/47, 62, 82, 92) in the through components (11, 20, 30, 40, 61, 80, 87/90). Bores, passages and grooves (71, 72; 81, 83) in cylinder liner (70) and central tube (80) interact in a motion-controlling manner with recesses (76, 76') and bores (78, 78') of the piston (75). <IMAGE>

Title: Ohmic load control by triac regulating unit - has no:voltage circuit breaker and galvanic disconnection between control and load
IPC: G05F1/45
Filed: 1971-02-10
Abstract: Triac regulating unit control of ohmic load has no voltage circuit-breaker and galvanic disconnection between control and load. The AC power supply of an ohmic load is controlled in accordance with a binary output signal of a regulator by pulse width control. The no-voltage circuit-breaker ensures the triac is fixed only in the zero passage of the sinusoidal AC voltage. The modulated binary output signal of the regulator is passed to the control input of the triac (Tr) via an interconnected DC voltage transformer (W) and a transistor. The transistor is connected in series to the control input of the triac (Tr).

Abstract: Block coded digital data is communicated with associated overhead data in a data stream having a succession of coded blocks (106, 108 ... 110). Each block contains N symbols wherein M of the symbols (102) comprise information to be transmitted and the remaining N-M of the symbols (104) comprise error correcting data. The ratio M/N comprises a first information rate. The coded blocks (106, 108 ... 110) in the data stream are divided into a succession of frames (144, 146, 148, 150, 152, 154), each comprising F of the coded blocks. A frame overhead symbol (112) is added for each of the frames, to provide data necessary for a receiver function such as synchronization. The addition of the frame overhead symbols effectively lowers the first information rate to a second information rate M'/N', where M/N = (M' + b)/(N' + b) and b is an integer chosen to provide the second information rate at a desired value. N is less than 2<n> + 1, where n is the number of bits in each of the symbols. The number of coded blocks F in each frame is determined from the relationship F = M'P/(N-M)b. P is the smallest value integer that will render F an integer, and is also the number of overhead symbols added per frame. A plurality of X of the frames are formed into a superframe (100) containing FX coded blocks and PX frame overhead symbols. X is chosen to provide enough n-bit frame overhead symbols to implement the desired receiver function. <IMAGE>
Patent JP-H083488-B2 (JP)
IPC: G01N33/542
Filed: 1986-02-13
Abstract: A method and device for determining the presence of an analyte in a sample suspected of containing the analyte is disclosed. The method involves contacting a test solution containing the sample and a first member of a specific binding pair with an end portion of a strip of bibulous material capable of being traversed by the test solution through capillary action. The first member of a specific binding pair is capable of binding the analyte. The strip contains a second member of a specific binding pair integral therewith for concentrating and non-diffusively binding the first sbp member at a small situs on the strip separated from the end portion of the strip. The detectible signal is produced in relation to the presence of the analyte in the test solution. The test solution passes through the situs as the test solution traverses the bibulous material. After the test solution has been allowed to traverse at least a portion of the strip, the strip is contacted with a developer solution containing members of a signal producing system in a manner that provides contact of the developer solution with the small situs following its contact with the test solution. The strip is then contacted with any remaining members of the signal producing system. The detectible signal produced at the situs is then compared with the signal detectible at a portion of the strip other than the situs to determine the analyte in the sample. In one embodiment of the invention the signal produced at the small situs has a sharp-edged distinctive pattern that provides a sharp contrast to the signal produced at adjacent sites on the strip when analyte is present in the test solution.

IPC: F16K7/00
Filed: 1989-02-22
Granted: 1996-06-26
Abstract: A culture bottle assembly has a container divided into two compartments by a flange. A closure and flexible septum seals the container from the outside environment. A frame inside the container is moveable between two positions. In one position the two compartments are sealed from each other, and in the second position fluid communication exists between the compartments. The frame has an elongated member and a skirt. The skirt engages the flange to form a seal. Downward force in the elongated member causes the skirt to flex. Cooperating means create a gap between the skirt and the flange when the skirt flexes. The flexible septum covers the elongated member thereby allowing force to be applied to the elongated member without opening the container. A solid media holder has trays for holding solid media in the upper compartment.
