Patent CA-1049131-A (CA)

Abstract: ABSTRACT         An active impedance multiplier circuit that can, as one of its uses, be used in a mine ground fault detec-tion system.  The purpose of the multiplier is to create a very high impedance for an AC signal that normally flows through a low impedance legitimate load.  To accomplish this, the output of the multiplier is put in parallel with the low impedance load and impresses upon the load an appropriate voltage and current.  When used in a fault de-tecting system, the impedance multiplier will act to normally prevent current from flowing in the low impedance load.  AC current will flow to the legitimate load from the multiplier in response to signals obtained from an alternating current detector located within each multi-plier.  In its most basic form, the active impedance mul-tiplier can be said to consist of a current detector and a current amplifier to amplify the detected current by a constant factor.  The amplified output from the multiplier is in turn connected in parallel across the legitimate load.

Abstract: Abstract of the Disclosure To produce a pile fabric, particularly a pile carpet, a fibrous batt, in which the fibres are transversely oriented, is cut into longitudinal strips which are then turned through an angle of 90 ° about their longitudinal axes by means of pairs of conveying wires, which run in paths from oppositely located guiding grooves of a pair of input rollers to guiding grooves located side by side in the surface of a depositing roller by means of which the fibres, which are now standing on end, are applied to an adhesive backing.  A feature of the invention is the use of conveying wires for turning the longitudinal strips, as contrasted to conveying belts which have previously been used for that purpose.

Abstract: ABSTRACT OF THE DISCLOSURE:     An improved truck trailer having a main frame at least one support axle fixed to the main frame at the rear thereof and a steering bogie positioned beneath the main frame and rear-wardly of the support axle. The stearing bogie comprises a secondary frame and a bogie axle fixed to the secondary frame.          The secondary frame is free to swing laterally about a front vertical pivot connecting it to the main frame. This swinging movement, occuring during cornering, turns the bogie axle in an opposite direction to the trailer turn to make the latter turning easier.

Abstract: Abstract of the Disclosure:    N,N'-dimethyl-perylene-3,4,9,10-tetracarboxylic acid di-imide is obtained as a valuable pigment of a pure red shade, by reacting perylene-3,4,9,10-tetracarboxylic acid anhydride at low temperatures with a dilute aqueous solution of at least the four-fold molar amount of methylamine.  The so-obtained bis-ammonium salt of the bis-N-methyl amide is then heated without isolation to effect ring closure while spiitting off two mols of water and two mols of methyl amine.  The product can be used without any finish operation or cah be after-treated to yield a pigment of an exceptionally high trans-parency or of a good hiding power.

Abstract: ABSTRACT OF THE DISCLOSURE Laser micromachining apparatus for producing a selectable machining pattern on a workpiece, for example a substrate of paper or rubber or for producing a silicon integrated circuit.  A high power laser beam carrying a con-trollable sequence of light pulses passes through a variable attenuator unit and then through a beam expander unit before impinging on a mask containing an enlarged pattern of the mark to be machined.  The pattern in the mask consists of a suitable arrangement of small apertures.  After diffraction through these apertures and focalisation by a converging optical element, the laser light passes through an optical imaging unit which images the mask onto the workpiece to pro-duce said selectable machining pattern thereon.

Abstract: RANDOM ACCESS MEMORY FOR IMAGE PROCESSING OPERATIONS          ABSTRACT OF THE DISCLOSURE      A conventional word organized random access memory is modified for image processing operations so that the pq image points of any 1 x pq, pq x 1 or pxq subarray of an rp x sq or smaller image array stored in the memory can be extracted or updated in a single memory cycle.  The invention contemplates 2 pq memory modules labeled from 0 to 2pq-1 for storing the image points, each module being capable of storing rs/2 points in distinguishable cells, only one cell of which is ran-domly accessible in a single instant of time.  The invention further contemplates accessing circuitry for causing each image point I(i,j) of an image array to be routed to or from a memory module M(i,j) accord-ing to the relation M(i,j)=pq[(i/p)//2] + (iq+i/2p+j)//pq, where the notations "/" and "//" denote, respectively, the quotient and the remainder resulting from integer division.  The accessing circuitry additionally causes image point I(i,j) to be stored into or retrieved from a cell location A(i,j) of module M(i,j) according to the relation A(i,j)=(i/2p)s+(j/q).

Abstract: ABSTRACT OF THE DISCLOSURE         The present invention relates to a method of removing mercury-containing contaminations from gases by passing the gas to be purified through a filter bed which is devised to make effective gas contact.  The method is characterized in that the filter bed is comprised of specific material prepared by binding, onto a carrier substance such as granulated pumice, a sulfurous substance as contamination absorbin agent.  The sulfurous substance may be a naturally occurring or synthetic sulfide of lead, cadmium, antimony, arsenic, iron, nickel and zinc and may be subjected to a surface activation pretreatment.  The invention is specially adapted to remove contaminations in refinery effluent gases, especially those containing vaporized mercury metal, together with absorption on the filter bed material.  The process uses a mechanism by which mercury, which has a high vapour pressure, is converted into its sulfide, which shows very low vapour pressure, by contacting the gas with sulfides of other metals.

Abstract: ABSTRACT OF THE DISCLOSURE "Improvements in dispensers"     A dispenser for dispensing liquid and paste-like compositions has an inner flexible container for receiving the composition and a pressure-resistant outer container.  A propellent gas is introduced through a filling valve into the annular chamber between the con-tainers.  The composition in the inner flexible container is thereby pressurized and can be dispensed by actuation of a dispensing valve whose base closes the mouth of the inner container.  The rim of the valve base is rolled over the rims of the inner and outer containers to connect the parts together.  A sealing edge is defined on the rim of the outer container and on the rim of the valve base and thus the inner container is engaged with sealing line contact on both sides thereof.  A sealing composition is also described as confined between the rims of the inner and outer containers.
