Patent CA-2196243-A1 (CA)
Inventor: DIEPOLDER WOLFGANG
IPC: F02C7/06
Filed: 1997-01-29
Abstract: The invention relates to a bearing arrangement for rotors 1 of jet engines with a bearing 4, which is mounted on a rotor carrier 7 via a bearing carrier 5.      In the event of failure, for example if the blade of a compressor rotor breaks, damage to or destruction of the rotor carrier 7 or of the housing should be prevented by the fact that a breaking piece 8 breaking under a defined load is arranged concentrically between the rotor carrier 7 and the bearing carrier 5. In this way the transfer of extreme radial loads to the rotor carrier 7 or to the rotor housing enclosing it is largely avoided, provided that the rotating member 1 has not yet come to a standstill. The bearing arrangement in accordance with the invention is particularly of interest for turbo jet engines for aeroplanes, where for example, in the case of a damage of a fan-rotor blade, the effect of a destructive force of a rotor running at high speed on neighbouring housing areas can be reduced.

Patent CA-2212434-A1 (CA)
Title: Dual-wavelength pumped low noise fiber laser
Inventor: BALL GARY A
IPC: H01S3/06
Filed: 1996-03-06
Abstract: A dual-wavelength pumped low noise fiber laser includes a fiber laser (10) comprising a pair of Bragg gratings (14, 16) at opposite ends of a fiber laser cavity (18) which is co-doped with two rare-earth dopants, ER+3 Yb+3, so as to allow lasing to occur at a lasing wavelength .lambda.L. A first pump signal (20) efficiently pumps the Yb to the excited state and the Yb energy is transitioned to the Er atoms which ultimately lase at the desire lasing frequency. Because Yb is pumped so efficiently, high pump absorption is achieved, thereby providing high laser output power and, consequently, reduced RIN.  Simultaneously, a second pump signal (52) directly pumps the Er at a different wavelength .lambda.P2 which populates the lacing transition more quickly, thereby allowing sufficient bandwidth of a closed loop control on the second pump signal (52) to control low frequency RIN spiking due to relaxation oscillations in the laser.

Title: Secret communication and authentication scheme based on public key cryptosystem using n-adic expansion
Inventor: NAITO SHOZO
IPC: G09C1/00
Filed: 1997-08-08
Abstract: A secret communication and authentication scheme based on a public key cryptosystem in which a decryption speed is improved while maintaining a security level. In the RSA type secret communication, a plaintext is expressed in a form of a k-digit n-adic number and a ciphertext is obtained by applying a calculation using the first public key n and the second public key e to the n-adic number and transmitted. Then, from the received ciphertext, a lowest digit of the n-adic number is decrypted by using the first public key n and the second secret key d, upper digits of the n-adic number are sequentially decrypted by using a decrypted value of the lowest digit of the n-adic number at the receiver side, and the plaintext is recovered by using decrypted values of respective digits of the n-adic number. The Rabin type secret communication can also be realized by the similar scheme. Moreover, the same principle of the n-adic pubic key cryptosystem can also be used in realizing the RSA type or the Rabin type Authentication.

Title: Process and amplitude or phase monopulse radar device for locating flying objects
Inventor: KUEPFER HANSPETER
IPC: G01S13/44
Filed: 1996-04-09
Abstract: The process and the corresponding phase or amplitude monopulse radar device are used for position measurement of a first target (TT1) and if need be, a second target (TT2) detected by the radar beam from the direction x1, y1; x2, y2. For a first measurement axis x (e.g. azimuth), the extended monopulse antenna (HA, PA) of the radar device has at least three subantennas (A, B, .OMEGA.) that are disposed in such a way, and have directional characteristic curves of such a nature, and whose signals are combined with one another and weighted in such a way that two antenna functions FO1 (x) / Fs (x) = F1 (x) = F1p (x) + j F1q (x) , with F1p (x) or F1q (x) = 0 FO2 (x) / Fs (x) = F2 (x) = F2p (x) + j F2q (x) , with F2p (x) or F2q (x) = 0. are formed, which are linearly independent of each other, purely real or purely imaginary, and independent of target offset positions perpendicular to the first measurement axis. The function course of these antenna functions F1(x) and F2(x) is measured for the single-target case and the function values that are dependent upon the target offset position x are stored in the memory unit (MEM). Measurement values F1 ACT = F1p ACT + F1q ACT, in the two-target case with F1p ACT, and F1q ACT =  0, F2 ACT = F2p ACT + F2q ACT, in the two-target case with F2p ACT, and F2q ACT =    are determined according to the antenna functions F1 and F2 for the targets (TT1, TT2) of position x1 and x2 detected by the radar beam, after which a processor (PROC) takes the equation given below for the amplitude monopulse process (index A) or for the phase monopulse process (index ~) and solves it for the target directions x1 and x2 by using the stored function values:     For amplitude monopulse radar devices, the three subantennas (A, B, .OMEGA. or .OMEGA., C, D) that are provided for each measurement axis x;y, and whose main radiation directions are disposed in one plane, have a common phase center. For phase monopulse radar devices, the three subantennas (A, B, .OMEGA. or .OMEGA., C, D) that are provided for each measurement axis and whose main radiation directions are disposed in one plane and run parallel to one another, have phase centers that are disposed on a common line. The subantenna (.OMEGA.) which is respectively disposed in the center between the subantennas (A and B or C and D), is used as a reference element.

Title: Post-translational activation of tgf-.beta.1 involving the tsp-1 receptor cd36
Inventor: KHALIL NASREEN
IPC: A61K38/00
Filed: 1996-05-17
Abstract: A protein called transforming growth factor-beta (TGF-.beta.) is important in causing the inflammation and progressive scar tissue in pulmonary fibrosis. The TGF-.beta.1 isoform is important in the pathogenesis of pulmonary fibrosis. It is usually secreted non-covalently bound to a latency associated peptide (LAP) which renders it biologically inactive. The inactive form is called latent TGF-.beta.1 (L-TGF-.beta.1). Activation of L-TGF-.beta.1 involves L-TGF-.beta.1/TSP-1 complex which interacts with the TSP-1 receptor, CD36, to process L-TGF-.beta.1 to the mature form in the presence of plasmin. Synthetic or natural CD36 peptides or fragments thereof can be used to prevent activation of TGF-.beta.1 in mammalian alveolar macrophages, thereby controlling the inflammation process.

IPC: G07F17/12
Filed: 1998-01-20
Abstract: A vending machine for dispensing power and telecommunications access is disclosed.  The vending machine has a switchable power circuit that receives power from a power source and delivers the power to the customer's equipment via a power connector under the control of a central control unit.  A customer interested in purchasing power or using the telecommunications access makes a payment into the payment processing unit which forwards the payment information to the central control unit.  From time to time the central control unit reports the transaction information to a central computer system via its modem which is connected to a telecommunication channel.          Access to the same telecommunication channel or another channel can be made available to the customer via a switchable telecommunications access circuit which is also under the control of the central control unit.  The customer connects to the telecommunications channel via the telecommunications access connector.  The central control unit provides information on the progress of the vending transaction to the customer via the user interface.  The central control unit determines when the transaction is completed by sensing the cessation of power usage via the power usage detection circuit or via customer action at the user interface.  The vending machine may be incorporated within a storage locker, or may be incorporated with telephones in telephone booths, kiosks, and similar structures.  The vending machine may also be used to dispense electricity, telecommunications channel access and other utilities to buildings and vehicles, including cars, boats and airplanes.
