Abstract: A ferritic, heat-resistant steel whose behavior at high application temperatures is improved by the combined addition of oxygen affinitive elements. Apart from stabilizing the electric resistance of heating elements by addition of zirconium, titanium and rare earth metal, also the creep elongation of the steel is considerably reduced under load at temperatures above 900 DEG  C., the thermal stress capacity thus being increased. The resulting complex oxide coating increases the protective function with regard to preserving the metallic cross-section in continuous and/or cyclic heat treatments. The steel is composed of: up to 0.10 % C up to 0.80 % Si 0.10 to 0.50 % Mn up to 0.035 % P up to 0.020 % S 12 to 30 % Cr 0.10 to 1.0 % Mo up to 1 % Ni 3.5 to 8 % Al 0.01 to 1 % Zr 0.003 to 0.8 % rare earth metals 0.003 to 0.30 % Ti 0.003 to 0.050 % N remainder Fe and incidental impurities.

Patent NO-180811-C (NO)
Inventor: SOMMERVILLE IAIN DOUGLAS
IPC: H04W12/06
Filed: 1991-10-17
Abstract: In a cellular telephone network, subscribers each have a token (such as a smartcard) by means of which they respectively identify themselves to the network. Each subscriber logs into the network by using his smartcard which inputs a unique identification number (IMSI) into the network. The relationship between each IMSI and the corresponding subscriber's telephone number (MSISDN) is random and stored in a home location register (HLR). When a subscriber activates a mobile using his smartcard, a visitor location register (VLR) at the relevant cell cheks for presence of the IMSI and the corresponding MSISDN. If they are not present, it extracts them from the HLR. When a replacement smartcard is issued to a subscriber, the new IMSI is stored in the HLR in association with the IMSI of the previous smartcard. When the replacement smartcard is first used, the relevant VLR will note its absence and will follow the same routine as specified above - by accessing the HLR. Not only will it thus obtain and store the MISISDN for the subscriber in association with the IMSI of the new smartcard, but this will also activate the HLR to note first use of the replacement smartcard, cancel all reference to the IMSI of the previous smartcard, and inform the administration centre of the network.

Date Nov. 16, 1995A heat exchanger has been developed with a helical insert (9) permanently mounted in a housing (2). Between the windings in the insert (9) there is formed a helical channel (20) for one heat exchange medium. The insert (9) is designed with a channel (10) for the second heat exchange medium. The heat exchanger is designed with a central tube (13) which is axially movable and rotatable. The central tube (13) is designed with scraper elements for removal of deposits in the channel (20). In one embodiment the scraper element is formed by a helical insert (15) of the same design as the insert (9). The insert (15) is designed with a channel (16) for the second heat exchange medium. In a further embodiment the central tube (13) is designed with one or more scraper arms (23) which may be liquid-cooled. Deposits are often formed on the heat transfer surfaces. A cleaning cycle is performed by means of axial movement of the insert (15) which is mounted on the central tube (13) towards the permanently mounted insert (9), thus causing the heat transfer surfaces to touch each other. A rotating movement is then performed, e.g., a part of a turn, while the surfaces are close to each other or in contact with each other, thus causing the deposits on the two surfaces to be rubbed or scraped off and thereby cleaning the channel (20).

Inventor: BOTSTEIN DAVID
IPC: G01N33/566
Filed: 2000-01-19
Granted: 2005-05-19
Abstract: The invention concerns compositions and methods for the diagnosis and treatment of neoplastic cell growth and proliferation in mammals, including humans. The invention is based on the identification of cardiotrophin-1 gene amplified in the genome of tumor cells. Such gene amplification is expected to be associated with the overexpression of the gene product and contribute to tumorigenesis. Accordingly, the cardiotrophin-1 polypeptide encoded by the amplified gene is believed to be a useful target for the diagnosis and/or treatment (including prevention) of certain cancers, and may act as a predictor of the prognosis of tumor treatment.

Title: Motor control apparatus and method
Inventor: PICKERING WILLIAM
IPC: B60L3/00
Filed: 1990-02-20
Granted: 1996-01-23
Abstract: Motor control systems are commonly associated with motors found on electric industrial vehicles, such as lift trucks.  Advantageously, the control of such motors should be optimized such that current is timely supplied to the motors in conjunction with selection of the appropriate motor direction.  The instant apparatus 10 includes a logic device 24 for receiving speed and direction demand signals from respective speed and direction selection devices 20,22.  The logic device 24 responsively produces respective motor speed and direction command signals.  A motor control device 26 receives the command signals and directs the electrical current from a power source 18 through the motor 12.  A transducer device 38 senses the actual direction of electrical current flow through the motor 12 and produces responsive feedback signals.  The logic device 24 produces at least one motor direction interrogation pulse in response to receiving the speed and direction demand signals and prior to delivering the motor command signals.  The interrogation pulse directs a small amount of electrical current from the power source 18 through the motor 12, insufficient to actually cause rotation of the motor 12.  The logic device 24 then compares the direction demand signals and the direction feedback signals and determines if and when command signals can properly be delivered to the motor control device 26.

Abstract: There is described an analytical instrument for the analysis of fluids such as biological fluids. The instrument includes a fluid dispensing system having a pipette for dispensing fluid test samples and test reagents to assay cartridges. An optical detection system provides a light beam which intercepts a downward travel path of the pipette prior to its reaching the dispense position. Measurement of the intensity of the light beam in conjunction with the position of the pipette enables a controller to indicate the presence or absence of a pipette tip. In addition, interception of the light beam by the pipette initiates a final approach sequence for the pipette to the dispense position above an assay cartridge by a predetermined increment of travel.

Title: Method and arrangement for frequency synthesis
Inventor: DENT PAUL WILKINSON
IPC: H03L7/197
Filed: 1990-12-13
Granted: 2000-11-21
Abstract: The present invention relates to frequency syntheses with a controlled oscillator (20) included in a phase locked loop, where the frequency of the oscillator output signal is divided (22) periodically by different integers, such that the frequency is, on average, divided by a value which is equal to an integer N plus or minus a numeric fraction whose absolute value is smaller than one. The phase position of pulses formed in this way is compared with the phase position of pulses which derive from a reference signal (20, 12), therewith forming a phase error signal. For the purpose of suppressing periodic variations of an oscillator control signal as a result of phase jitter, there is added or subtracted to the phase error signal, in a known manner, a correction value (24, 26) which is dependent on the aforementioned numeric fraction. Tn order to eliminate the need to multiply the correction value by a factor which is proportional to the inverted value of the integer N, the phase error signal is instead amplified with a factor N (28) prior to adding or subtracting the correction value. The loop bandwidth is also held constant in this way.

Title: Method and apparatus for determining availability of a public base unit for communicating with a cordless telephone in a public cordless telephone system
Inventor: LYNN DALE EVERETT
IPC: H04W24/00
Filed: 1992-05-15
Granted: 1996-07-30
Abstract: A public cordless telephone system includes an arrangement for informing a public handset unit when it is within the reception range of a public base unit even though all communication channels are then occupied or all public baseunits in the reception area are then busy communicating with other handset units. In operation, each public base unit while communicating with any public handset unit inserts in the communication channel it is then occupying spectrum energy such as is provided either by a pilot signal or a frequency shift keying (FSK) signal. By providing this additional spectrum energy along with normal voice signal energy in the communication channel, a public handset unit while searching for an available channel and interrogating this channel will be able to determine, even though the channel is occupied, that there is a public base unit within its reception range. If no available communication channel is found and a signal from one or more public base units is detected, the handset unit generates a first alerting signal for its user thereby informing the user of the one or more public base units in the area even though a telephone call may not be initiated due to all of the communication channels then being occupied. If an available communication channel is found, an attempt to establish communication with a public base unit is initiated by the handset unit over this available channel. If no response is received from a public base unit and if a signal from one or more public base units is detected, the handset unit generates a second alerting signal which thereby informs the user of the one or more public base units in the area even though a telephone call may not be initiated due to all of these public base units then being busy.
