Title: Method and device for applying a pattern onto a support means
Inventor: JOHANSSON PATRIK
IPC: B32B37/10
Filed: 1998-05-18
Abstract: A method and device for applying a pattern (70) onto a support means (2) of a sign, utilising a foil (17) comprising a pattern layer (18) and a carrier layer (73) with an adhesive layer (74) uniting them, said pattern being cut out in the pattern layer of the foil by means of a controlled cutting device, after which the foil is placed on a laminating table (3) in an application device (1). According to the invention a traverse (21) is passed in controlled manner over the foil placed on the laminating table, and a self-adhesive transfer film (19), supplied from a roll (20) over and around a press roll (34) rotatably journalled, at a press device (32) is applied under pressure on the foil. The carrier layer and spill of the pattern layer are removed and the pattern parts thus remaining are brought into contact with the support means, with the adhesive layer of the pattern parts now exposed. The press roll is then again passed over the transfer film, pattern parts and support means so that the pattern parts are transferred permanently to said support means, after which the transfer film is removed from the support means.
Patent CA-2289915-A1 (CA)
Inventor: KLINGEMANN HANS
IPC: C12N5/08
Filed: 1998-04-30
Abstract: This invention relates to a natural killer cell line termed NK-92. The invention provides a vector for transfecting a mammalian cell which includes a nucleic acid sequence encoding a cytokine that promotes the growth of NK-92. Additionally, the invention provides an NK-92 cell, or an NK-92 cell modified by transfection with a vector conferring advantageous properties, which is unable to proliferate and which preserves effective cytotoxic activity. The invention further provides a modified NK-92 cell that is transfected with a vector encoding a cytokine that promotes the growth of NK-92 cells. The cell secretes the cytokine upon being cultured under conditions that promote cytokine secretion, and furthermore secretes the cytokine in vivo upon being introduced into a mammal. In a significant embodiment, the cytokine is interleukin 2. The present invention also provides methods of purging cancer cells from a biological sample, of treating a cancer ex vivo in a mammal, and of treating a cancer in vivo in a mammal employing a natural killer cell, such as NK-92 itself, an NK-92 cell which is unable to proliferate and which preserves effective cytotoxic activity, or natural killer cells transfected with a vector encoding a cytokine.

Title: Fraud monitoring system
Inventor: EDWARDS ALEXANDER FRASER MILES
IPC: H04M3/36
Filed: 1998-07-15
Abstract: In order to detect fraudulent or potentially fraudulent usage of a telecommunications network, each call connected by way of one of the digital main switching units of the network (3a to 3c) has an associated billing record transferred to a fraud management system (4). The fraud management system compares the origin and destination of the call with a known usage pattern for the originator and, if other indications are that the call is of a fraudulent nature, and the call deviates from the known usage pattern an alarm can be forwarded to an operator. The user profile used to determine normal calling behaviour is updated over a period of time in respect of calls determined as not fraudulent. An initial user profile may be generated from historic billing records.

Title: Rolling door with a flexible door leaf
Inventor: SCHUTTE WOLFGANG
IPC: E06B9/80
Filed: 1998-09-02
Abstract: A rolling door with a flexible door leaf which can be wound is rotationally mounted above the door opening and driven by a winding shaft. A closing strip whose length is smaller than the clearance width between lateral profiles at the door opening is fastened on the lower end of the leaf. A cable to tighten the door leaf has fasteners at each end and extends above reversing rollers mounted in the floor area.  Carriage-like blocks move vertically guided by the lateral profiles. Holding means detachably connect the blocks to the closing strip ends and have openings for the cable extending from the reversing rollers on the floor to the closing strip. After a crash, holding means comprising catching devices release the closing strip upon exertion of lateral forces and re-engage therewith when the blocks are pressed down so the rolling door automatically and easily returns to operation.

The inserted instruction is then executed and control returns back to processing of the original instruction set after execution of at least one interrupt instruction.
Patent CA-2305607-A1 (CA)
Title: Basketball net
Inventor: BOURDAGES RICHARD
IPC: A63B63/08
Filed: 2000-04-12
Abstract: The present device involves a basketball net modified to include elastic fibers that both narrow the circumference as well as add rigidity to the overall structure of the modified net. The modified net can be used to support an image only on the exterior face of the net and in a manner that could not be supported by an ordinary basketball net. As the ball passes freely through the constricted net, the net expands, causing the image to enlarge and become more visible. The kinetic effect of the ball expanding the net as it passes through, renders the image more noticeable because: (i) the eye is drawn to the net when the ball passes through; (ii) the image becomes enlarged in size as the basketball passes through the net; (iii) the contrast of the color and texture of the ball behind the net. Moreover, coinciding the excitement of goal scoring with the advertiser's kinetic image can serve to "anchor" the image in the spectator's memory.
Patent CA-2306438-A1 (CA)
Inventor: KELLY DAVID
IPC: H02M3/335
Filed: 2000-04-20
Abstract: A power supply circuit uses a simplified design for converting AC to DC and powering a flyback transformer.      The switch of the flyback transformer operates at a high frequency and the time of the transformer is controlled to achieve a high power factor. The flyback transformer is fed a rectified AC signal which has not been smoothed in the traditional manner using a bulk hold-up capacitor and in rush limiting resister. Any filtering to smooth the output current or voltage is carried out on the secondary side. In some cases, no smoothing of the output current or voltage is necessary. The time on of the switch is changed if necessary, slowly, relative to the pulsating input signals powering the primary winding. With a fixed T on, or slowly varying T on, a high input power factor can be achieved.

Abstract: Method and apparatus for cleaning an open surface of a body of liquid, especially for recovering oil spills or other floating pollutants. A surface portion of the water carrying pollutants is caused to flow across a skimming weir forming an inlet to a collecting vessel and to proceed downwardly within the collecting vessel. At least the main portion of the downwardly flowing polluted water is then diverted laterally outwardly into a separation zone in which the pollutants are allowed to separate from the water and collect on a confined surface of the water. The separation zone may be integrated in the collecting vessel and provided around a central collection compartment provided with an annular skimming weir. Alternatively, the skimming zone may be provided in a separate vessel connected with the collection vessel through a conduit.

Title: Gas turbine aeroengine control system
Inventor: HATTORI YUICHI
IPC: F02C9/28
Filed: 2000-07-28
Abstract: In a control system for a gas turbine aeroengine having a control unit made up of an electronic control unit (ECU) which calculates a fuel flow rate command value based at least on the detected rotational speed of the turbine and the desired power output and a fuel control unit (FCU) including at least a fuel metering valve which meters fuel to be supplied to the engine based on the calculated fuel flow rate command value, the ECU is integrally connected to the FCU, thereby reducing the size and weight of the control units and hence, reducing the occurrence of resonance which would otherwise be likely to occur.  In the system, an alternator is integrally connected to the FCU and the rotational speed of the turbine is detected based on the wave form generated by the alternator.  Moreover, the ECU calculates the fuel flow rate command value such that the fuel flow rate to be supplied to the engine is brought to a prescribed value. This makes it unnecessary to provide the overspeed protector.
