Title: Mains failure protection for refrigerated loads
Inventor: BRADSHAW JOHN
IPC: H02J9/08
Filed: 1994-09-27
Abstract: When a vehicle or trailer carrying a refrigerated load is parked, a refrigeration unit is powered from the mains supply, but if the mains supply fails a control circuit powered by the vehicle battery starts an on board donkey engine which then energises the refrigeration unit. Mains failure de-energises a sensing relay R1 having N.C. contacts R1 in the battery supply to the control circuit. Following a delay determined by a timer (T1 - provided in case the failure is of only short duration), glow plugs of the donkey engine are energised for a period determined by a timer T2, T2A and then a starter motor solenoid is energised for a period determined by a timer T3. Starter motor energisation is terminated if a detector circuit (Fig. 3) senses a satisfactory supply current from the donkey engine, but if the timer T3 times out without a satisfactory supply current being established, the starting process is re-initiated without the delay of timer (T1). A relay (R3, Fig. 4) prevents power being supplied from a restored mains supply while the donkey engine is running. The mains supply is reconnected after a delay, provided by a further timer, following operation of a reset switch (R2/2) in the vehicle cab. <IMAGE>

Patent GB-2291522-A (GB)
Title: Authentication technique
Inventor: DEROME MICHAEL FERNAND ALEXAND
IPC: G06K17/00
Filed: 1995-07-07
Abstract: A dual-secure authentication technique takes advantage of the inherently secure nature of certain data storage media, such as that based upon the structural variation, from place to place over a strip, of magnetic characteristic, to attach to a valued article a secure identity code. The security is further enhanced by incorporating that code, together with further data, "signing" the code and further data using the secret key of a crytosystem pair and attaching the signed information to the article. Authentication requires the signed information to be de-crypted using the public key of the cryptosystem pair and ensuring that the code so recovered tallies with that recorded in the secure medium. <IMAGE>

Title: Testing wells
Inventor: GRIFFITH MICHAEL
IPC: E21B17/20
Filed: 1995-07-14
Abstract: A new drill stem test apparatus and corresponding method includes a dual coaxial coiled tubing adapted to be disposed in the wellbore. The dual coaxial coiled tubing includes an inner coiled tubing 10a, and an outer coiled tubing 10b surrounding and enclosing the inner coiled tubing and forming an annular space 10c which is located between the inner coiled tubing and the outer coiled tubing. The annular space is adapted to contain a pressurized kill fluid. A first end of the outer coiled tubing is sealed by a sealing element 10d to a first end of the inner coiled tubing, the end of the inner coiled tubing extending beyond the sealing element and adapted to receive a formation fluid. The first ends of the inner and outer coiled tubing are disposed in a wellbore. A second end of the inner and outer coiled tubing is wound onto a coiled tubing reel and is connected to a kill fluid valve 22 and a formation fluid valve 26. When the kill fluid valve opens while the formation fluid valve is closed, a pressurized kill fluid fills and pressurizes the annular space between the inner and outer coiled tubing. While the kill fluid valve is still open, the formation fluid valve is opened. A formation fluid begins to flow from the formation through the inner coiled tubing and through the formation fluid valve. If the inner coiled tubing forms a hole and begins to leak formation fluid, the pressurized kill fluid in the annular space will prevent the formation fluid in the inner coiled tubing from leaking out of the interior of the inner coiled tubing and into the annular space. <IMAGE>

Patent GB-2308427-A (GB)
Title: Perforating gun
Inventor: BROOKS JAMES E
IPC: E21B43/117
Filed: 1996-10-18
Abstract: A perforating gun includes a multiplicity of shaped charges arranged in planes (16) each plane of charges including a plurality (N) of shaped charges and a detonating cord running down through the axial center of each of the plurality of planes of charges. The plurality (N) of shaped charges are equally spaced at an angle 360/N about the detonating cord. The plurality of planes of charges: (1) are rotated at an angle of 180/N relative to one another, and (2) are axially packed together along the longitudinal axis of the gun so that the charges in one plane are nearly touching the charges in the adjacent plane, yet they all share the same centered detonating cord. The proximity of one plane to another is close enough such that one plane of charges detonates within a few microseconds of its neighboring plane of charges. The close packing of the shaped charges (1) prevent the charge cases from expanding significantly upon detonation, and (2) prevent the charge cases from breaking up into numerous small pieces (large chunks of charge case debris results). A near-maximum packing density produces two unexpected properties: (1) a reduced swelling of the gun's diameter after detonation; and (2) a significant reduction in the amount of shaped charge case debris that can escape from the perforating gun.

Title: Temporary subsurface well sealing and equipment anchoring
Inventor: HENNIG GREGORY
IPC: E21B23/06
Filed: 1996-11-22
Abstract: Temporary subsurface well sealing and equipment anchoring A retrievable packoff assembly (0) for temporarily sealing a well pipe (11) and anchoring equipment is connected to a tubular actuation tool (24) which is manipulated from the surface to position the assembly at a subsurface well location, set the assembly and then released from the set assembly. Right-hand tool rotation sets the assembly, releases the tool (24), and is subsequently employed to reengage and unset the assembly for retrieval to the surface. A bypass flow passage in the assembly is controlled by a sliding sleeve valve (37) which is automatically closed by the right-hand tool rotation during setting and release and automatically reopened by tool rotation occurring during retrieval of the assembly. Flow through both the assembly and the bypass is confined within the actuation tool (24). A control flow passage in the apparatus is sealed by a retrievable blanking plug which may be removed to permit passage of equipment through the anchored assembly. The sealed assembly holds pressure from above or below. Drill pipe or other equipment may be supported in the well pipe (1) by the set assembly.

Title: Charging system for a photographic flash apparatus
Inventor: NOMURA HIROSHI
IPC: G02B7/10
Filed: 1997-01-24
Abstract: A system 500 for charging a main capacitor 530 in a photographic flash apparatus has a control circuit (210, Fig.29) which actuates a circuit 502, 510 for charging capacitor 530 and which simultaneously also enables a capacitor voltage detector circuit 577, 578 only whilst the charging circuit is being actuated. A high signal at a single control terminal CHEN both actuates the charging circuit, by turning on a transistor 501, and also enables the voltage detector, by turning on transistors 573, 576, thereby reducing the number of control terminals required for the flash apparatus. A voltage divider 577, 578 of the voltage detector is connected to an A/D converter input terminal RLS of a CPU (210). The sensing terminal RLS is only connected to the capacitor 530 when the transistors 573, 576 have been turned on and after the capacitor 530 has charged to the breakdown voltage of a zener 570. A low signal on terminal CHEN turns off the charging circuit and disconnects terminal RLS from capacitor 530. During a main charging program (Fig.50), capacitor 530 is charged until it reaches a maximum voltage or until a charging timer expires. The charger is disabled for three seconds if is stopped as a result of the maximum voltage being reached. During a photographing charging program (Fig. 61), capacitor 530 is charged until it reaches a minimum voltage enabling flashing or until the charging timer expires. The charging timer is normally set at 8 seconds. If charging is interrupted in the main program by actuation of an operation switch, or during the photographing program by release of a photometering switch, the time remaining for this charging operation is set into the charging timer as the time limit for the next charging operation.

Title: Multiphase fluid monitor
Inventor: SYME DUNCAN BRIAN CONDIE BROWN
IPC: G01N23/14
Filed: 1997-03-07
Abstract: The fluids in a pipeline 16 are characterised by detecting the prompt gamma rays emitted when the fluids are irradiated with fast neutrons from a pulsed neutron tube 30. The gamma rays are detected by an energy sensitive detector 36, and the number counted in energy windows. At intervals the fluid in the irradiated region is controlled to have a known composition, eg. empty, so the counts can be corrected for drifts in the baseline. This may be achieved using a bypass system. A scintillation detector 48 may be used to detect the gamma rays and rays originating from a fast neutron are distinguished from those from a thermal neutron by a time gate. Operation of the detector may be stabilised by observing a known peak in the gamma spectrum, and the counts also be corrected for any variations in neutron flux. The rate of flow of the fluid can also be determined.

Title: A system bus arbitration method
Inventor: YOON DAE-JUN
IPC: G06F13/368
Filed: 1997-04-01
Abstract: A bus arbitration method for use in a multiprocessor system having a plurality of agents and a system bus, for determining a sampling point at which bus arbitration-related signals on the system bus are latched, each of the bus arbitration-related signals representing a bus request signal asserted on the system bus by one of the agents for gaining an access to the system bus, wherein the system bus is arbitrated during an arbitration period in synchronization with a bus clock signal formed by a train of clock pulses generated at each clock period, the arbitration period being greater than N but not greater than (N+1) clock periods with N being a positive integer. At a first step, an initial sampling point is set at a predetermined point on a clock pulse. At a second step, the bus arbitration-related signals are latched at the initial sampling point to thereby select, as a subsequent sampling point, the predetermined point on an (N+1)st clock pulse generated after the clock pulse on which the initial sampling point is set, if one or more bus request signals are asserted, and the predetermined point on a next clock pulse, if no bus request signal is asserted.

Title: Semiconductor read-only memory device and method of fabricating the same
Inventor: WEN JEMMY
IPC: H01L21/8246
Filed: 1997-05-14
Abstract: In a ROM device of the type including an array of MOSFET memory cells, the bit lines BL1,BL2 are formed by forming, on an insulating layer 41 on a semiconductor substrate 40, a substantially grid-like semiconductor structure including a plurality of substantially parallel-spaced first portions 43a,43b oriented in a first direction and a plurality of substantially parallel-spaced second portions 50a-50f oriented in a second direction. The first portions 43a,43b are ion implanted and serve as bit lines, and the second portions 50a-50f serve as channels underlying word lines WL1-WL3. In the code definition and implantation process, a selected number of the channel regions 50a-50f are diffused with impurities through a mask so as to set the associated memory cells with a first threshold voltage representing the storage of a first binary digit; while the threshold voltage of all the other channel regions that are not diffused with impurities are set to a second threshold voltage representing the storage of a second binary digit. In such a method the bit lines are not formed by diffusing impurities into the silicon substrate, and so the drawbacks of lateral diffusion, junction leakage, and reduced breakdown voltage are not experienced.

Title: Channel selecting system
Inventor: HASHIMOTO TAKESHI
IPC: H04N5/45
Filed: 1997-05-16
Abstract: A first channel selection signal generating circuit 3 successively indicates selection of channels which can be received by an electronic tuner 1. A second channel selection signal generating circuit 4 indicates selection of a particular channel. A channel selection signal switching circuit 2 effects switching between these two outputs so as to output one of them to the electronic tuner 1. A digitizing circuit 6 converts the output from the electronic tuner 1 and a scan line converting circuit 7 outputs a signal which has been formed from the digital signal by reducing the number of horizontal scan lines so that the output is stored into a texture memory 8, as one sub-frame image for each channel. A graphics engine 9 subjects the image data loaded from the texture memory 8 to a 3D image process, forms a polyhedral icon with the sub-frame for each channel on a respective face, and stores it into a video image memory 10. A video signal selecting circuit 11 switches the output between the video signal from the electronic tuner 1 and the video signal loaded from the video image memory 10 so as to output the selected one on a display unit 12.

Title: Subscriber Terminal for a Wireless Telecommunications System
Inventor: LYSEJKO MARTIN
IPC: H04B7/26
Filed: 1997-11-20
Abstract: A subscriber terminal comprises a first signal processing unit (110) associated with an antenna to transmit and receive signals over the wireless link at first frequencies within an operating frequency band. The first signal processing unit comprises a frequency converter for converting signals between said first frequencies and a second frequency. A second signal processing unit (130) is provided remote from the first signal processing unit and associated with an item of telecommunications equipment. The second signal processing unit is formed from signal processing circuitry which is independent of the operating frequency band, the signals being passed between the first signal processing unit and the second signal processing unit at the second frequency via a connection medium (120) connecting the first and second signal processing units. Hence, the same second signal processing unit can be used irrespective of the operating frequency band used for the wireless communications between the subscriber terminal and a central terminal. Further, the above approach significantly reduces the amounts of circuitry required within the first signal processing unit associated with the antenna and typically located outside a building.
