Title: Electrical fuse
Inventor: EHLMANN ARLIE HERMAN
IPC: H01H85/22
Filed: 1990-04-24
Abstract: The high speed fuse employs stamped end bells (12) and terminals (14) rather than forged or machined parts. A slot (16) for the terminal is punched through each end bell. The terminal is inserted into the slot in the end bell and staked in position. This ensures a strong tight fit without requiring welding or soldering. One end of each terminal has coined ridges (44) to facilitate automatic welding of the fuse link (30) to the terminals. Round balls (18) are used to seal the fill holes (20) for the arc quenching material. Metal pins (41) secure the end bells within the fuse housing (40) but are not electrically connected to the terminals if the end bells are made of electrically insulating material. <IMAGE>

Title: Combustion chamber assembly in a gas turbine engine
Inventor: BURNELL ANTHONY DAVID
IPC: F23R3/10
Filed: 1991-04-30
Abstract: Overrich regions of fuel mixture in the combustion chamber of a gas turbine engine are dispersed by a jet of air directed into the region. Plumes of fuel/air mixture from adjacent airspray burners overlap to create overrich regions which tend to produce soot.

Title: Toner monitoring in printers
Inventor: LE SUEUR ERIC JOHN
IPC: G03G15/08
Filed: 1991-09-11
Abstract: In a laser printer, in which a latent image is generated on a circulating imaging member in accordance with digital image signals and subsequently developed with toner, the number of pixels to be toned is used as an indication of the rate at which toner is being depleted from the developer mixture. The device for dispensing fresh toner to the developer mixture is operated in dependence on the number of pixels to be toned so that there is a pre-established relationship between the pixel count and the length of time for which the dispensing device is in operation (31). As the efficiency of the dispensing device varies, the pro-established relationship is adjusted by measuring the toner density of the developed images as well (32). If a predetermined length of time for toner supply is reached, this is shown that the supply of toner in the printer is low on monitor (33). <IMAGE>

Title: Data validation system.
Inventor: JACKSON CHRISTOPHER RICHARD
IPC: G07F7/12
Filed: 1992-11-14
Abstract: A data validation system for checking the validity of identity devices such as credit cards and passbooks comprises a central database maintained by a central computer 1 which is linked to a number of local checking units LC1, LC2, LC3, each of which in turn may be connected to a plurality of identity device readers located at, for example, supermarket checkouts in order to detect erroneous or fraudulent transactions. Each checking unit has a processor for performing the validity checking function which uses the first of a sequence of databases of the checking unit, and will only utilise the subsequent databases in the sequence if no corresponding identity is found in the first database. The checking unit databases are updated from the central database. The use of a sequence of databases for each checking unit saves processor time, and allows updating of the databases in the sequence at different frequencies and by different means including physical transfer and by communications link. <IMAGE>

Title: Video special effects system
Inventor: LINDHOLM DENNIS A
IPC: G06T15/10
Filed: 1992-11-25
Abstract: A video special effects system and method includes at least one signal system operating in real time to transform one or more input video signals to generate an output video in response thereto, a work station, an operator control panel and a control system communicating with the signal systems, the work station and the control panel. A control surface, preferably defined by one or two control curves, are developed at the work station and subsequently used by the control system to define a video effect in which portions of the input video images are selectively mapped to the control surfaces and subsequently manipulated to define an output video image. The control system operates to define each parameter controlling the output image at selected event times and to individually interpolate each given parameter between the event times at which the parameter is defined. The signal systems generate the output images in response to input images and the instantaneous values of control parameters defined by the control system. The video image is treated as a plurality of patches, each of which is identified by four coordinates and which coordinates are transferred onto the control surface to generate transformation addresses for the video signals. <IMAGE>

Patent GB-2296350-A (GB)
Title: Data processing divider enabling reduced interrupt latency
Inventor: JAGGAR DAVID VIVIAN
IPC: G06F7/535
Filed: 1994-12-21
Abstract: A microprocessor is described having an arithmetic unit that includes a dedicated hardware divider responsive to a plurality of different divide instruction codes to generate respective multi-bit portions of a quotient. Each divide instruction can be early terminated when the partial remainder is detected as being zero. Furthermore, subsequent divide instructions to calculate the remaining bits of the quotient can be skipped in response to a flag (Zflag) set within a current programming status register. In the described embodiment, a 32-bit divisor and 64-bit dividend serve to produce a 32-bit quotient and a 32-bit remainder. The generation of the 32-bit quotient takes place in response to four different divide instruction codes each responsible for generating a respective 8-bit portion of the quotient. With each instruction, a register pair originally holding the dividend holds instead a progressively smaller number of bits of the remainder and a progressively larger number of bits of the quotient. As each portion of the quotient is calculated more quickly than a 32-bit quotient, interrupt latency is reduced. <IMAGE>
