Title: Computer system and method
Inventor: LIN MAXWELL
IPC: G06F12/06
Filed: 1989-02-09
Abstract: Disclosed is a method of determining different capacity types of RAMs (3-5), especially DRAMs, in a computer system with a plurality of banks of IC memory sockets having a fixed number of address lines (2) Fig. 3 attached for installing the RAMs thereon. The method comprises first assuming a bank of RAMs to be a first type and filling each location of the bank of RAMs with first data, and then assigning second data to a second location of the bank of RAMs. The address of the second location is chosen so that the first data are overwritten by the second data if the memory is a 256KB memory but are not overwritten if the memory is a one MB memory. The content of the first location of the bank of memories is then checked. If the content of the first location is found to be the first data, then the bank of RAMs is determined to be the assumed first type, however, if it is discovered to be the second data, then the bank of RAMs is determined to be a second type, otherwise the bank of RAMs is either empty or out of order. <IMAGE>

Abstract: A switch cover, for use in conjunction with an electric plug, comprises a web portion (1) of thin and substantially flat plastics material provided with holes (2, 3 and 4) for receiving the pins of a conventional wall plug, and a cover portion (5). When the pins of a plug are inserted through the holes (2, 3 and 4), and the plug is inserted into a socket, the cover portion (5) extends across the switch of the socket, preventing the switch from being turned off. Desirably the cover portion (5) extends on two sides of the web portion (1) so as to be effective in covering either a left-hand or a right-hand socket switch. The portion (5) may be of channel section and enclose current and/or temperature indicator lamps. The shape of the cover, which may be secured to the socket or the plug, is designed to make removal of the plug from the socket difficult. <IMAGE>

Title: Catalyst stripper unit and process in catalytic cracking operations
Inventor: HOLMES PHILIP
IPC: B01J8/18
Filed: 1989-07-12
Abstract: A novel catalyst stripper unit and a catalyst stripping process for catalytic hydrocarbon cracking operations are described. The stripper comprises a stripper vessel (60) containing stacked, vertically separated, perforated trays (63), each having an overflow weir (65) defining the maximum depth of a layer of catalyst particles thereon. Each weir (65) forms the top end of a respective downcomer tube (66) which delivers catalyst particles from one tray to the tray immediately beneath at a location which is diametrically opposite the weir (65) of that tray so that particles must pass across the tray before overflowing the weir and descending to the next lower tray. Steam (or another stripping medium) is passed (72) into the bottom of the stripper vessel (60) and rises via the perforations in the trays and via the layers of fluidized particles of catalyst maintained thereon by the weirs (65), thereby stripping hydrocarbon materials from the catalyst particles. The steam containing stripped hydrocarbon materials may be received above the stripper vessel in a separator (12) forming part of the catalytic cracker reactor, and stripped catalyst particles are recovered from the base of the stripper vessel.

Patent GB-2232516-A (GB)
Title: Sense amplifier driver for semiconductor memory
Inventor: SEO SEUNGMO
IPC: G11C7/06
Filed: 1990-02-28
Abstract: A sense amplifier 40 is driven by sensing clock pulses Qs via sensing clock driver 10 which comprises a plurality of inverters IV10IV30IV50. IV50 contains a plurality of n-channel MOS transistors Ts1 to Ts3 with gates interconnected by successive resistors R1b R12 to produce a multistepped switch-on of sense amplifier 40 when Qs goes high. When Qs goes low n-channel pulldown transistors Tf1 to Tf3 ensure that transistors Ts1 to Ts3 switch off simultaneously and rapidly. On switch-on the multistepped pulse reduces the peak current required, whilst on switch-off the pull-own transistors prevent dissipation occurring in otherwise open current path via p-channel transistor c in IV30 and n-channel transistors Ts1 to Ts3. <IMAGE>

Title: Still video playback apparatus with single memory for sound and picture signals
Inventor: SAKAI NOBUYA
IPC: H04N5/91
Filed: 1990-06-20
Abstract: Sound and still picture signals are stored on magnetic disc 25 with the sound signals being time axis compressed, allowing up to 20 seconds of sound to be stored with each picture. On play back the sound signals are expanded to their original duration using RAM 53. The picture signals are directed by switch 45 to RAM 53 so that a steady flicker free picture output 43 is obtained. Directing both sound and picture signals via RAM 53 obviates the need for a second RAM. <IMAGE>

Title: Interferometers
Inventor: HAYES DAVID
IPC: G01S3/14
Filed: 1990-11-07
Abstract: To determine the angle of arrival of an incoming signal S, the direction finder comprises two spaced apart multibeam receiver arrays 4, the determination of the angle of arrival being carried out in three stages, first, by determining which of the beams 6 of each of the arrays 4 receives the largest amplitude signal, second, by comparing the relative phases of the signals received in the selected beam 7 of each of the arrays 4 and third by comparing the selected output 8 with the output from adjacent beams in either of the arrays, thus interpolating between the signal received in the selected beam 7 with signals received in adjacent overlapping beams 10 to resolve phase ambiguity.

Abstract: An input signal circuit used in a factory automation apparatus, which is constituted by a bidirectional conduction circuit 13 for connecting to an AC power source 11A or DC power source 11B, 11C with both plus or minus common line, a constant current circuit 15-18 for supplying constant current, and a load circuit 14, 21, 22 accepting the constant current. When the voltage range is less wide, a bidirectional conduction circuit and a filter circuit are used. The circuit is responsive to the ON/OFF states of a switch 12 to apply binary data to a following circuit 22. A bidirectional conduction circuit 13 e.g. a full wave rectifier, enables the use of AC or DC as preferred. The constant current circuit 15-18 enables the output binary pulse to be of constant amplitude. Need for rectifier 13 may be obviated by connecting two constant current circuits employing opposite conductivity transistors in anti-parallel. <IMAGE>

Title: Optical amplifier
Inventor: MINELLY JOHN DOUGLAS
IPC: H01S3/23
Filed: 1992-03-23
Abstract: An optical amplifier for amplifying signals of different wavelengths throughout a spectral window modifies the amplification of each signal such that the output levels of the signals are more equal than the input levels thereof when the input levels differ by more than a predetermined amount. In one embodiment this is achieved by providing a dichroic reflector 120 at one end of an amplifying fibre so that standing wave patterns are set up in the amplifying fibre by interference of the forward and reflected signal lights, at the different wavelengths, the signal at each wavelength preferentially decreasing its own gain with increasing signal level. In other embodiments the different wavelengths are spatially separated by the use of a two core optical fibre or by a grating arrangement. <IMAGE>
