Patent CA-2010007-A1 (CA)
Inventor: BRERETON COLIN
IPC: C23C18/42
Filed: 1990-02-14
Abstract: ABSTRACT Metal Mesh And Production Thereof In the production of an open valve metal mesh comprising a plurality of interconnected strands a part only of which are coated with an electrocatalytically-active material, a coating of a valve metal oxide is formed on those parts of the surfaces of the strands of the mesh which do not have a coating of an electrocatalytically-active material. The mesh may be formed by slitting and stretching a sheet of valve metal which has been coated with an electrocatalytically-active material, the valve metal oxide coating being formed on those surfaces, eg those exposed by the slitting step, which do not have a coating of an electrocatalytically-active material.

Title: Compensation of computed tomography data for objects positioned outside the field of view of the reconstructed image
Inventor: KING KEVIN F
IPC: G06Q50/00
Filed: 1990-02-15
Abstract: Abstract of the Disclosure An x-ray CT system acquires attenuation data over a field of view which is larger than the field of view of the reconstructed image.  The data used to reconstruct the image is compensated for the shading effects otherwise caused by objects outside the image, but within the x-ray path.  This compensation is accomplished with minimal impact on computation time by using a first order estimation of the convolution of the acquired attenuation data outside the image field of view.

Abstract: ABSTRACT            A navigational aid comprises a nousing with a flat, transparent liquid crystal display.  The display is flat and flush with the bottom of the housing, to allow the aid to be placed flat on a map or chart.  The aid is microprocessor controlled and accepts plug in memory modules, which contain information relating to an area through which a craft, for example, an aircraft, is to be navigated.  The display generates cursors which can be superimposed on the map.  The aid can display graphically the progress of the craft, superimposed on the map, on the  basis  of  input  data  supplied  by  the  user. Alternatively, the cursors can be moved to measure the distance between points on the map.

Abstract: The present invention provides a coated cellulosic web product and coating composition which provides enhanced toner adhesion for documents printed using noncontact printing devices such as ion deposition printers.  The toner adhesion enhancing coated cellulosic product and composition comprises a cellulosic web having first and second major surfaces with at least one of the major surfaces having coated thereon a layer of a polymeric toner receptor. The polymeric toner receptor layer preferably also includes an electrolyte to adjust the electrical conductivity of the cellulosic web to have a volume resistivity of between about 5.0x10 9  and 1.0x10 12  ohm cm.  The toner receptor layer is applied at a coating weight of from about 0.3 to about 2.0 lb/ream. The invention provides printed documents which can withstand the normal automated handling operations commonly encountered by business documents such as checks, other MICR coded documents, bar coded documents, and the like without the flaking off or removal of the toner from the document.  Further, documents printed on substrates utilizing the coating composition of the present invention have been found to have increased resistance to intentional defacement or alteration of printed information.

Abstract: Process for the synthesis of the N-methyl-3, 4-dimetoxyphenylethylamine of formula (see fig. I)                     I   intermediate in the synthesis of the drug internationally known as verapamil.  The process starts from the 3, 4-dimethoxybenzaledhyde which, by means of a Darzens condensation, gives an epoxyester that, by alkaline hydrolysis and subsequent decarboxylation, gives the 3,4-dimethoxyphenylacetaldehyde.  This aldehyde gives the amine of formula I by reaction with monomethylamine followed by reduction with sodium borohydride.

Patent CA-2015443-A1 (CA)
Inventor: HOLLAND GORDON A
IPC: B66B1/50
Filed: 1990-04-25
Abstract: A hydraulic elevator includes level sensors for establishing dead zones of different sizes and for changing the dead zone while the car is stopped at a floor. A controller selects the size of the dead zone, for purposes of relevel operations, based upon elevator operating state (e. g. doors open or closed, time of day, time since last run) or other parameters (excess oil temperature, motor temperature, or excess motor starts). The controller also selects an effective hysteresis value either to return the car to floor level or to move the car to a position above floor level. In this manner, the controller maintains a small dead zone, and returns the car to level, when the doors are open. When the doors are closed, a larger dead zone is selected to reduce the frequency of relevel operations. Moreover, under certain conditions, the car is moved, during releveling, to a position above the landing, to further reduce the number of required relevel operations over time.

Abstract: DE LA RUE GIORI S.A.              LAUSANNE/SWITZERLAND           ABSTRACT            Method for fixing printing plates onto a cylinder of an intaglio printing machine and installation for implementation of the method.            In order to fix two plates  (3,  4)  onto the cylinder formed by a sleeve (1) or by a plate cylinder of an intaglio printing machine,  two axial grooves  (2)  are formed on the cylinder such that the plane of one of the lateral faces of each groove (2) forms an angle with the axis of the cylinder. A strip (5, 6), whose face adjacent to the end of the plate is perpendicular to said plate, is welded onto the concave face of the two ends of each plate (3, 4). The edge of each plate (3, 4) projecting beyond the corresponding strip (5, 6) is then cut off such that the edge of  the plate  forms  a continuous surface with the face of the strip, and such that the sum of the lengths of the plates equals the length of the periphery of the cylinder. The plates are then arranged on the cylinder (1) by introducing the neighboring strips (5, 6) into a groove (2) and the free space in the groove is completed by a wedge-shaped strip (7)  in order to tension the plates and obtain an edge-to-edge join.

Title: Fuel additive mixing system
Inventor: CLUFF JAMES R
IPC: B01F15/04
Filed: 1990-07-20
Abstract: FUEL ADDITIVE MIXING SYSTEM                 Abstract of the Disclosure A system for metering a fuel additive into a flow of fuel into a fuel tank includes a mixing unit coupled to the filler neck of the fuel tank.  The mixing unit has a body with an axial main flow passage, having a fuel inlet and a mixture outlet.  The fuel inlet is dimensioned to receive the standard nozzle found on conventional service station pumps for motor fuel.  The body also has an additive inlet that communicates with the main flow passage through a metering passage controlled by a metering valve.  The metering valve is actuated by a pivot arm having a first end that is in the flow path of fuel flowing through the main flow passage and a second end that engages one end of a pushrod, the other end of which engages a valving element in the metering valve.  The flow of fuel against the first end of the pivot arm causes the pivot arm to pivot so as to push the pushrod against the valving element to move the valving element away from its seat, against the force of a biasing spring, to open the metering valve.  The metering valve is thus opened in proportion to the flow of fuel through the main flow passage. The bias applied by the spring to the valving element can be varied to change the proportional relationship between the metering valve opening and the flow of fuel.
