Patent CA-2019050-A1 (CA)
Inventor: NABI GHULAM
IPC: C21C5/56
Filed: 1990-06-14
Abstract: This invention provides a method and appratus whereby steel of various compositions may be produced from iron ore and coal through a series of stages without the intermediate production of liquid iron.  A reforming reactor receives top gases from the steel making reactors, and converts them to high reduction potential gases which are returned to the steel making reactors.  The iron ore and reductants, such as coal, are charged to a controlled atmosphere reactor which may be an inclined rotary cylindrical shaft.  From the controlled atmosphere reactor the charge is moved to a potential shift reactor which is inclined or vertical and encounters increasing heat and rising gases for converting  the carbonised sponge into a semi-molten state.  The charge then passes to a high temperature reactor where it encounters the reducing gases from the reforming reactor and preheated oxygen to create temperature in which steel is made.  Hot gases from the  high temperature reactor pass through the PSR and the CAR and  are returned to the reforming reactors to complete the cycle.

Abstract: ABSTRACT        The present invention relates to a removably-mountable integral lighting system having an elongate battery housing which  includes  a  first  lighting assembly mounted to its forward end,  and a second lighting assembly mounted to its rear  end.    Each  end of the  housing  includes  means  for engaging a structural member.  The length of the housing can be  axially  adjusted  to  allow removable  mounting  of  the system between the structural members of a vehicle and to accommodate  mounting  spaces  of  different  sizes.     The elongate housing includes at least two sections which are axially movable with respect to one another and are spring biased to allow compression of the spring when one end of the housing is moved toward the other for producing a force of securement when the housing is  positioned in a space between two structural members which space is smaller than the overall length of the housing in an uncompressed state.

Abstract: ABSTRACT          Giant  BRICKS made of concrete are commonly used material   in the  construction industry.  Top of each  preceding layer  of bricks  is covered by mortar and each brick of the subsequent layer is carefully positioned on the mortar, so that it is in line  with  allready  placed  bricks  both  horizontally  and vertically.   It  is  time consuming and it  takes  a skilled tradesman  to  built a proper wall.  The concrete bricks  are also heavy,  which makes hand manipulation with them tedious.          Therefore  a  new type a of giant bricks  was  developed  as described further.

Title: Sheet-guiding foil as dressing for backpressure cylinders and sheet-transfer cylinders in sheet-fed offset printing presses for perfecting
Inventor: APPEL WERNER
IPC: B41N7/00
Filed: 1990-08-22
Abstract: ABSTRACT   During the passage of the sheet through a printing press, the freshly printed side of the sheet comes into direct contact with the sheet-transfer cylinders; in perfecting, after the turn, the freshly printed side of the sheet is additionally pressed onto the impression cylinders of the following printing units.  In order, nevertheless, to be able to print to a consistently high quality, it must be ensured that there is as little buildup as possible of printing ink on the outer cylindrical surfaces of sheet-transfer cylinders and impression cylinders.  A sheet-guiding foil as dressing for such cylinders is therefore proposed.  The surface of said foil is textured and is provided with an oleophobic, wear-resistant and incompressible silicone layer.  The good ink-removal characteristics of the foil result in a minimal buildup of ink on the sheet-transfer and impression cylinders.

Abstract: Cross-linked labelled antibody conjugates are described which have at least one non-disulphide interchain bridge. The bridge may be the residue of a homo- or heterofunctional cross-linking reagent, and is located away from the antigen binding domains of the antibody. The antibody conjugates have an enhanced binding capacity and in vivo have good blood clearance and, in the presence of a tumour high tumour: blood and tumour: bone ratios. The conjugates are of use in the diagnosis and therapy of e.g. tumours and may be prepared by reaction of a cross-linking reagent with an antibody.

Title: Real-time dynamic holographic image storage device
Inventor: LEFLEUR SHARON S
IPC: G03H1/02
Filed: 1990-03-02
Abstract: A real-time dynamic holographic image storage device uses four-wave mixing in a pair of photo-refractive crystals (10, 14). An oscillation is produced between the crystals (10, 14) which can be maintained indefinitely after the initial object beam is discontinued. The object beam produces an interference pattern in a first crystal (10) to produce a phase-conjugate object beam which is directed towards the second crystal (14). In the second crystal (14), another interference pattern is created which produces a reconstructed object beam. The reconstructed object beam is directed back towards the first crystal (10). The interference patterns are produced by the interaction of the object and phase-conjugate object beams with a read and write beam in each of the crystals (10, 14). By manipulation of the ratio of the read and the write beam intensities in at least one of the crystals (10, 14), the phase conjugate or reconstructed object beam output therefrom can be amplified to maintain stable oscillation between the two crystals.

Abstract: The object of the invention is to propose a method for the regulation of a brushless DC motor, in which the current ripple of the motor is minimised. To this end, on reaching the desired value of the motor current (IM), a switchable semiconductor valve (Tr1, ..., Tr4) in the bridge arm which is being acted on is switched off for a time period (ts) governed by the speed of the motor. In consequence, the clocking frequency of the switchable semiconductor valves is also minimised, which contributes to a considerable reduction in motor noise as well as increasing the life of the transistors. <IMAGE>

Title: Method for detecting maternally transferred drug metabolites in newborn infants
Inventor: OSTREA ENRIQUE M JR
IPC: G01N33/94
Filed: 1992-04-13
Abstract: An improved method for detecting the presence of drug metabolites in the meconium of newborn infants is described.  The method involves a single step extraction of the drug metabolites from meconium using a buffered aqueous solution containing methanol in an amount between about 10 and 30 % by volume and buffered to a pH between 6 and 7 and then assaying the extract individually for the presence of the drug metabolites.  The method is particularly useful for detection of cocaine, morphine, cannabinoid and amphetamine metabolites; however, any drug metabolite in the infant meconium can be tested if it is extracted by the solution from the meconium.  Various assay methods are used for the drug metabolites in the solutions derived from the meconium, including immunoassays, fluorescent assays and mass spectroscopy.  The method provides a means for early detection of drug presence in newborn infants which contribute to infant illness.
