Title: Microbiological purification of water and a microorganism for use in said process
Inventor: VALO RISTO J
IPC: C12N11/12
Filed: 1989-08-08
Granted: 1994-04-19
Abstract: Abstract The invention relates to a process  for the microbiological purification of water which is polluted by contaminants such as chlorophenols. The purification is performed with the aid of microorganisms which degrade the contaminant in question, whereby the feed water is directed through a biofilter which captures the contaminant so that the water is  essentially cleaned and the contaminants  are enriched in said filter. Microorganisms which have been previously immobilized on the biofilter are made to degrade the contaminant captured in said biofilter.  The purification of  huge  amounts  of  water  is quicker  and  the  size  of  the  apparatus  smaller when  the relatively slow biodegradation can be performed as a separate second step of process. The process is especially suitable for the purification of cold waters, which normally are difficult to purify. In the present process only the water circulating in the  biofilter during the  biodegradation stage  need be heated to a temperature which is suitable for bioactivity. The invention  also  relates to  a novel microorganism  which can be used in said process as well as to a solid support con-taining  immobilized  chlorophenol-degrading  microorganisms which can be used as a biofilter.

Title: Additive composition for treating water used to form ice and methods
Inventor: RZECHULA MICHAEL J
IPC: C09K3/24
Filed: 1989-09-29
Granted: 1999-06-08
Abstract: The problems associated with patching, sealing and forming ice due to water run off and large imperfections on skating rinks is solved by the use of an additive for treating water which comprises a polymer selected from the group consisting of water gelling starches and polymers of acrylic acid and sodium silt commonly referred to as super absorbent polymers and means for dispersing the polymer in water. The polymer absorbs water, which may be tap water at a temperature in the range of 45-45°F, producing a generally homogenous mixture with slush-like consistence, when mixed with the water. The mixture may then be applied where patching, sealing or the formation of ice is required. The frozen mixture formed has desirable characteristics for skating.      The invention also encompasses novel methods for patching, sealing and forming ice.

Abstract: The invention relates to a method and apparatus for measuring at least one of the parameters flow rate, flow velocity, concentration and quantity of radon and/or radon daughters in the ground. The method is characterized by collecting gas arriving from the ground in a first chamber which is gas-permeable at the bottom thereof, at least the downwardly extending boundaries of the chamber being in contact with the ground, so that atmospheric gas is prevented from passing into the chamber. At least one detector which measures alpha-radiation from the decomposition of radon and radon daughters is placed in a second chamber communicating with the first chamber. Positioning of the second chamber and the detector is selected so that the detector can continuously be observed and utilized for the measuring operation. The gas is allowed to pass continuously. through the chambers over a given period of time, to expose the detector to the gas. Subsequent to this exposure, the measuring result registered on the detector is evaluated. The method can be modified for measuring radon departure from the surface of the ground, the gas-permeable first chamber being arranged over the surface of the ground to be analyzed. The detector is placed in a second chamber communicating with the first chamber. For the purpose of measuring the flow rate and velocity of radon passing through the ground there is provided a first chamber beneath the level of the ground, at a desired depth. This first chamber is connected with a gas-impermeable passage to a second chamber which can be readily reached from the level of the ground and which is sealed against penetration of atmospheric air. The detector is placed in the second chamber.

Abstract: In a cellular radio network in which mobile stations roam, in addition to location updating of each mobile station with the accuracy of one location area, a so-called temporary subscriber-specific paging area is determined. Each mobile station initiates the determining of the temporary paging area in the subscriber data base of the cellular radio network after being located in a cell for a sufficiently long period. The temporary paging area is smaller than the location area (e.g., one cell and possibly at least one adjacent cell), and thus the paging of a mobile station can be focused on a small area, i.e., the temporary paging area. It is thus unnecessary to page over the entire location area, and paging time can be reduced and capacity of the cellular radio network spared.

Abstract: 894,672. Semi-conductor devices. PHILIPS ELECTRICAL INDUSTRIES Ltd. June 27, 1958, No. 20704/58. Drawings to Specification. Class 37. A wire, at least the envelope of which is aluminium, and which is coated with a layer of oxide of sufficient thickness to enable fusion of the aluminium to take place without breakage of the oxide layer, is fused to a semi-conductor material. The oxide layer should have a thickness of from 3 to 40 microns and the semiconductor material and the material inside the aluminium envelope of the wire may be germanium or silicon, and tin may be used to connect the semi-conductor device to a base-plate. The device may be a diode or a transistor and in one embodiment (Fig. 3, not shown) it may be sealed inside an evacuated casing. A device according to the invention may be constructed by degreasing an aluminium wire by washing in caustic soda solution, nitric acid and then water and then oxidizing the surface either by dipping in a solution of H3PO3, CrO3, NH4HF2, and (NH4)2HPO3 in water or by subjecting the wire to anodic treatment at 60 volts D.C. in a solution of oxalic acid in water. The end of the wire may then be cut and polished and held in contact with a silicon body by means of a graphite jig (Fig. 2, not shown), while the whole device is heated in an oven to cause fusion to occur. Copper wire or cable may then be spotwelded to the aluminium wire at a point some distance away from the semi-conductive body.

Abstract: A device for transmitting torque from a power unit to a drill string or other rotary pipe, and which is constructed upon reverse rotation to preferentially break a threaded con-nection between the device and a stand of the pipe without dis-connecting a plurality of lengths of pipe in the stand from one another.  The torque transmitting device includes a tubular struc-ture having a thread adapted to be advanced into engagement with a thread at an end of the pipe, and a shoulder ring carried by and rotatable with the tubular structure and having a shoulder engageable against a shoulder of the pipe to limit advancement of the threads together, with axial forces being transmitted from the tubular structure to the ring by interengageable bear-ing surfaces which permit limited rotary movement of the struc-ture and its thread relative to the shoulder ring.  The bearing surfaces are constructed to retain the ring in a predetermined fixed axial position relative to the tubular member, preventing axial movement of the ring relative to the structure as the struc-ture turns about its axis relative to the ring.  A C-spring dis-posed about the tubular structure acts to yieldingly urge the ring rotatively relative to the structure in a joint breaking direc-tion.  Two elements connected to flanges formed on the tubular structure and ring respectively are received between opposite ends of the C-spring and act to apply the force of the spring to the ring to urge it rotatively relative to the structure in the joint breaking direction.  Pins received radially between the tubular structure and the ring limit their relative rotation to an angle constituting a small portion of a turn.

Title: Transposed multi-channel switching
Inventor: BESHAI MAGED E
IPC: H04Q11/04
Filed: 1990-09-21
Granted: 1993-04-20
Abstract: ABSTRACT         A synchronous time division multiplexing system for multi-channel calls involves dividing each frame into a first segment and a second segment each containing substantially the same number of time slots and dividing the number of channels of the multi-channel call into a first subset and a second subset each containing approximately the same number of channels.          Thereafter, the first subset is assigned to the first segment of the first frame and the second subset to the second segment of the first frame.  The invention involves in a first time switching stage transposing the first subset to the second segment of the first frame such that the channels within the first subset occupy eligible free slots and retain their relative order and transposing the second subset to the first segment of the next frame such that the channels within the second subset occupy eligible free slots and retain their relative order.  The call subsets are thus transposed during a single stage of time switching.  By assigning the selected slots in each segment in an ascending order, the output samples of a call will appear in the proper order but will not be properly positioned in the frame.          When the transposed subsets are likewise switched in a second time-switching stage, the call samples will be positioned properly in the frame.  Thus, traversing an even number of time switches, from source to termination, guarantees both frame consistency and the desirable slot order.

Granted: 2001-05-01
Abstract: A laminated stator assembly for an electric motor includes plate laminations which have square-trimmed edge segments separated by circular peripheral edge sectors, which plates are randomly oriented in assembling the stator to provide a generally cylindrical outer surface. In this manner, the stator can be enclosed in and supported by an outer motor shell or housing which is substantially thinner and less expensive. The stator assembly of the present invention enjoys the material savings and enhanced air cooling characteristics of prior art stator constructions utilizing square-trimmed laminations, but eliminates the detrimental aspects of difficult alignment and heavier motor housings. In addition, overall stator assembly is substantially simplified.
