Patent CA-2057326-A1 (CA)
Inventor: HOLMQVIST SVANTE
IPC: G01V3/10
Filed: 1991-12-10
Abstract: The invention relates to a method of determining elec-tromagnetically the locations of electrically conductive bodies beneath the surface of the ground, wherein a primary electromagnetic field is generated with the aid of a loop through which a sinusoidal alternating current is passed.  The loop is placed at or above the level of the ground beneath which the locations of conductive bodies shall be determined.  There are generated in the conductive bodies currents which, in turn, generate a secondary electromagnetic field, wherein the values of the amplitude and phase of the magnetic component of the thus formed total electromagnetic field are measured in three linear independent directions with the aid of coils mounted inside a probe which is lowered to differ-ent depths in a borehole which extends down into the ground within the propagation area of the primary field. The measured values are transmitted through a transmis-sion line to a receiver, as are also the values for determining the phase of the primary field, so as to enable the phase difference between the primary field and the total field to be calculated.  This difference is used to determine the three real and three imaginary components of the secondary field, these components in turn being used to determine the location of the conduc-tive bodies.  The invention is characterized in that the values of the primary field phase are measured continu-ously by at least one reference coil which is placed outside the probe, either above or beneath the surface of the ground, within the propagation area of the prima-ry field.  the reference coil is orientated so as to re-ceive at least one component of the magnetic field and the signals obtained from the reference coil, or the result of processed signals, are transmitted to the receiver on a transmission line.

Title: High tg polymer and redispersible powder for use in hydraulic portland cement mortar and concrete
Inventor: KUHLMANN LOUIS A
IPC: C04B28/02
Filed: 1992-01-21
Abstract: ABSTRACT       Polymers with a high glass transition temperature are used in cement additives to produce a portland cement mortar or concrete that does not have the initial stickiness typical of prior art polymer-modified portland cement compositions and does not form a crust on the surface when exposed to air drying, thus improving the working time of the mix.  This simplifies equipment cleaning and permits the use of transit mixers for field applications of polymer-modified concrete. The properties of the mortar and concrete modified with these materials, both in the plastic and hardened state, are equivalent or superior to those of the currently available products which use film-forming materials. Within the scope of this invention are a redispersible powdered cement additive, a redispersible polymer powder and a ready-to-use portland cement composition, as well as related processes.

Abstract: A METHOD FOR CONTROLLING THE DIAMETER OF TUBULAR FILMS MADE IN BLOW MOULDING PLANTS                         ABSTRACT           A method for controlling the diameter of tubular films, which are manufactured in a blow moulding apparatus comprising an extruder with a film blowing head, an internal cooling means for the blown film, a calibrating means, a means for laying the film flat, and a means for film take-up.  The exchanged amount of internal cooling air, the speed at which the extruder supplies plastic to the blowing head, the temperature of the extruded plastic material, the take-up speed, and the external cooling are automatically controlled in response to sensing means.  To be able to carry out the control easily and without failure, without having to accurately measure the height of the frost line,  the distance is measured from the tubular film in the vicinity of the inflection point of the blow-up region to at least one stationary sensor.  A first control circuit responds to deviations of the distance from a predetermined setpoint, to increase or decrease the exchanged amount of internal cooling air, to restore the predetermined setpoint.   The diameter of the tubular film is measured above the frost line,  and a second control- circuit responds to deviations of the diameter from a predetermined setpoint to appropriately adjust any or all of the following variables:  the temperature of the plastic material, the speed at which the extruder supplies plastic to the blowing head, or the take-up speed of the film, to maintain the diameter setpoint.

Title: Method and apparatus for rendering waste substances harmless
Inventor: RITTER ROBERT A
IPC: C02F11/06
Filed: 1992-09-30
Abstract: A method and apparatus are provided for the treatment of hydrocarbon-contaminated soil by chemical hydrolysis and/or oxidation of the hydrocarbons in the hydrocarbon-contaminated soil. The method includes conditioning lime with a particularly-specified fatty-acid activator. The conditioned lime is blended with physically-preconditioned, moist, hydrocarbon-contaminated soil, the degree of blending being at least near microscopic level. A charge of the blended lime/soil is conveyed to an enclosed reaction vessel, where hydration of the lime is carried out. The heat of the hydration reaction is retained within the vessel, so that hydrolysis of the fatty acid conditioner and/or hydrocarbon contaminants in the soil is effected. Air or oxygen-enriched air is substantially-simultaneously introduced into the reaction vessel together with steam and/or water as required by the chemical reactions, thereby to effect a flameless, intermediate-temperature oxidation of the hydrocarbons and their hydrolysed degradation products. Decontaminated soil product is discharged from the reaction vessel by passing the decontaminated soil product, in dry, dusty, hydrophobic form, through a treating zone where it is sprayed with a surfactant. The surfactant-treated solid is passed to a blender where it is mixed with sufficient water to provide a substantially dust-free decontaminated soil product.

Title: Correlated active attenuation system with error and correction signal input
Inventor: ERIKSSON LARRY J
IPC: G10K11/178
Filed: 1992-11-04
Abstract: An active acoustic attenuation system atten-uates a correlated input acoustic wave and eliminates the need for an input transducer sensing such wave.  An output transducer introduces a canceling acoustic wave to attenuate the input acoustic wave and yield an attenuated output acoustic wave.  An error transducer senses the output acoustic wave and provides an error signal.  An adaptive filter model has a model input, a model output outputting a correction signal to the output transducer to introduce the canceling acoustic wave, and an error input from the error transducer.  A summer has a first input from the model output, a second input from the error transducer, and an output outputting a resultant sum to the model input, such that the model input is provided by the sum of the correction signal and the error signal.
Patent CA-2085269-A1 (CA)
Inventor: AARON CALVIN
IPC: H04Q11/08
Filed: 1992-12-14
Abstract: A transmission scheme serially propagates time slot data to a plurality of TSI modules with time slot data contained in one TSI frame being serially transmitted from module to module in a daisy-chain technique. A dedicated outbound transmission bus transmits the frame of data from one module to a dedicated inbound transmission bus of another module. The outbound and inbound data buses are connected by separate buses on a backplane which is coupled to each of the TSI modules. Preferably, the TSI modules do not transmit selected ones of the stored data to end destinations until the last TSI module has received the frame of data so that all modules can begin the transmission in time synchronization. Maximum transfer data rates can be achieved since undesired transmission line characteristics or disruptions are minimized by the use of dedicated input and output transfer buses between the modules. Additional modules can be added without disrupting the transmission data rate between existing modules, thereby permitting a growable TSI facility without adversely impacting the data transmission rate between modules.

Abstract: ABSTRACT         An easily-installable support capable of accommodating a wide variety of fiber optic cables is disclosed.  The fiber optic cable support uses a one-piece, variable diameter mechanism for cushioning and spacing the supported cable.  The support is also contoured to increase the surface area available to contact a utility pole or other structure and includes one or more cleats or gains which provide additional contact strength by biting into and gripping wooden or similar poles.  The support is designed to provide approximately constant compressive pressure to the supported sections of a length of cable and sufficient pressure to avoid the need to apply grit or other loose friction-increasing substances to the cushion interior.  Because it is of relatively constant or slowly varying cross-section, the support can be die formed with minimal disruption of the fluid flow within the die.
