Patent EP-0516179-A2 (EP)
Inventor: RABE GEORGE B
IPC: F16L55/16
Filed: 1988-07-22
Abstract: A pressurizable tool for locating a sleeve within a surrounding tube and pressure-tightly sealing the sleeve within the tube to repair leaks in the tube. The tool includes a housing containing an axially movable piston and a forward reduced diameter portion and having an elastic expander unit for inserting into the sleeve and tube in a tubesheet. The expander unit consists of at least two elastic rings composed of an elastomer material and each having a chamfer provided at the outer edge of the unit forward and rear faces. By pressurizing a port at the housing front end, the piston is moved rearwardly to axially compress and expand the expander rings radially outwardly sufficiently to expand the sleeve firmly into the tube and provide a pressure-tight seal therebetween. Following such expansion of the sleeve, the piston is pressurized and moved forward to release the compression on the expander unit rings, so that the tool can be easily withdrawn from the expanded sleeve and tube and inserted into another sleeve and tube for repeated usage.

Abstract: A time-keeping apparatus for sporting events, in particular for homing pigeon prize flights, is intended to provide contactless, automatic time-keeping without the possibility of manipulation in conjunction with minimum disturbance for the participants. To this end, each participant is permanently fitted with a personalised identity tag whose register number is read at the finish by means of a reader using a binary-coded sequence of attenuations of the radio-frequency interrogation energy, and stored together with the decoding time, and displayed. In the case of homing pigeon sport, each pigeon is ringed with its register number, and in the case of other sporting events the sporting equipment (such as running shoes, cycle frames or the like) can be equipped with identity tags. Transmitting coils which are to be passed sequentially ensure the orderly finish of the participants in the event, while transmitting coils which are placed next to one another and are rapidly interrogated cyclically one after another by a multiplexer ensure individual time-keeping even when participants reach the area of the finish side by side at the same time. Since the arrival time linked to the register number is obtained as absolute time information via a radio clock, manipulations in this regard are also no longer possible. <IMAGE>

Abstract: Differential amplifier with signal-dependent quiescent current control, comprising:
     a first (T₁) and a second (T₂) transistor of the same conductivity type for conducting a first (I₁) and a second (I₂) current respectively, the two transistors comprising each a control electrode coupled to a first (6) and a second (8) input terminal respectively, for feeding an input signal, a first main electrode coupled to a common terminal (3),   converting means (10A, 10B) for converting the first and the second current to a measuring current in response to the first and the second current,   comparing means comprising a control output terminal (11) for presenting a signal (I S ) in response to the difference between the measuring current and the reference current (2I Q ) of a reference current source (14),   a controllable quiescent current source (4) coupled to the common terminal (3) for presenting a quiescent current (I O ) at the common terminal and having, coupled to the control output terminal (11), a control input (5) for controlling the quiescent current (I₀),    whilst the converting means comprise:
   a first/second current generator (10A/10B) for generating a first/second derived current (I A /I B ) which decreases if the first second current (I₁/I₂) increases and  vice versa ,   combining means (11) for generating the measuring current by adding together the first (I A ) and second (I B ) derived currents.   
     Due to the inverse characteristic of the first/second current generator, the measuring current will be increasingly more dominated by the smaller of the first and second currents in the event of an increasing input signal, so that the minimum value of the smaller current will be determined by the reference current. Generating the first and second derived currents and combining them to the measuring current is a continuous process and can therefore react fast to amplitude variations in the first and second currents.

Abstract: A method for operating a multiprocessor computer system (10) which includes cache memories (204, 210, 226) is provided. A system bus interface (232) initiates a bus write broadcast when a processor (202) writes to the cache memory, sets a SHARED indicator for the data item, monitors the write broadcast for a SHARED signal assertion on the bus, and clears the indicator in the absence of the SHARED signal assertion during the write broadcast. Backup cache memory(226) entry update versus invalidate decisions are made based upon the identity of write broadcast initiators. Cache memories have indexes which are a function of the cache size. A high speed multiplexer (262) selectively couples cache index information from each processor and bus interface to the backup cache memory. A lock register (254) helps synchronize processors.

Abstract: The porosity of the subsurface earth formation surrounding a borehole is investigated by measuring the populations of epithermal neutrons at detector locations longitudinally spaced from a neutron source. In this measuring process, a detector is located at a matrix density neutral (MDN) spacing from the neutron source at which effects of the matrix density of the earth formation are significantly reduced. The porosity measurements are determined from neutron counts detected at both the MDN location and other locations to derive formation porosity measurements which have reduced lithology and matrix density effects. Because of these reduced effects, formation porosity values derived do not need to be corrected to account for lithology and matrix density effects. In addition, the formation lithology and matrix density may be obtained.

Abstract: A process eliminates pattern shifting artifacts in a printed image by perturbing a threshold/image signal value relationship when a multi-level grey signal (VIDEO) is binarized. The process utilizes a programmable multi-level grey signal modifying circuit (5) for modifying the multi-level grey signal (VIDEO) by a predetermined value according to its grey level (see Fig.6) The modified multi-level grey signal (VIDEO) is binarized by a comparator (1) to a binary pixel signal according to a relationship between the modified multi-level grey signal (VIDEO) and a threshold value ("128"). The process further generates an error corresponding to the relationship and diffuses the error to neighboring pixels. The multi-level grey signal (VIDEO) is modified with either random noise multiplied by a grey level dependent coefficient or by a predetermined value from a checkerboard or vertical line pattern from a pattern generator (7; Figs. 4,5). The value from the pattern is dependent upon the grey level and pixel location of the image data. An apparatus for implementing the method is also disclosed.

Abstract: A subscriber identification module (SIM) for storing user-identities and other user specific information and thereby enabling access to the service of the radio system. One of the user identities is a Temporary Mobile Subscriber Identity (TMSI) used for user anonymity purposes by utilizing the TMSI as an alias for the actual user identity in order to avoid sending the actual user identity in the clear on the radio path. A part of the TMSI is a random number which cannot be used to identify the user/terminal without mapping information to the actual user identity, which is found in the telecommunications network entity that allocated the random number. SIM roaming from one radio system to another is possible by utilizing predetermined bits of TMSI to differentiate between different TMSI's of different systems by indicating in a uniform manner in all mobile radio systems the mobile radio system which has allocated the TMSI. The remaining bit locations of the TMSI provided in a mobile radio system-specific format. During an inter-system SIM roaming, the old TMSI will be copied from SIM and forwarded to a new mobile radio system. The new system will use the predetermined bits of the TMSI to identify the old system in order to request the actual user identity.
