Title: Detecting abnormality in fuel tank transpiration preventing system.
Inventor: YAMADA JUN
IPC: F02D41/00
Filed: 1992-03-25
Abstract: An apparatus for detecting an abnormality of a fuel transpiration preventing system which includes a canister 30 with an absorbing device 34 and a control valve 40 provided in a passage between a fuel tank 22 and an intake pipe 2 of an internal combustion engine, so that a fuel gas generated within the fuel tank is absorbed by the absorbing device of the canister and introduced into the intake pipe by opening and closing the control valve in accordance with an operating state of said internal combustion engine, includes a pressure detecting device 44, for detecting a pressure within the fuel tank or between the cannister and intake pipe 2, and a deviation calculating unit 50 responsive 40 the output of the pressure detecting device for calculating a deviation between the pressure detected when the control valve opens the passage and the pressure detected when the control valve closes the passage. The apparatus decides an abnormality of the fuel gas supply system on the basis of the deviation calculated by the deviation calculating unit. This arrangement allows accurate abnormality detection, indicated by lamp 60, throughout the fuel transpiration preventing system. The canister 40 preferably includes two pressure adjusting valves 35a, 35b which may be at the base of the canister or at the top (Fig. 5). A change over valve (33, Fig. 10) may be provided so that the cannister can be by passed. The pressure detecting device 44 may comprise a displacement member displaced by a pressure detected, a magnetic member attached to the displacement member and a Hall element which changes its output in accordance with the displacement, (Figures 15-17). <IMAGE>

Title: Active two-way radio repeater
Inventor: BIDWELL BRIAN ALFRED
IPC: H04B7/155
Filed: 1992-03-31
Abstract: The repeater has a port for connection to a system antenna, a port for connection to one or more local antennas and means (4, 5, 9, 10) for amplifying the radio signal in the repeater. Prior to and subsequent to amplification the radio signal passes through a frequency changer (2, 3, 7, 8) so that the signal is amplified at a different frequency to that of the received signal. The repeater comprises separate sections (A, B), each provided with the frequency changing means and the amplification means, the repeater sections being adapted for electrical connection and physical separation. Preferably the sections are constructed as discrete units each in its own housing, for instance with one section adjacent to the local antenna and another section adjacent to the system antenna. The oscillator signals supplied to the mixers in each frequency changer are preferably derived from the same oscillator. There may be one system antenna and two or more local antennas. <IMAGE>
Patent GB-2255507-A (GB)
Title: Thickened peroxygen compound containing compositions
Inventor: REVELL CHRISTOPHER
IPC: A01N37/16
Filed: 1992-05-08
Abstract: Many aqueous compositions containing a peroxygen compound have a very low viscosity and thus easily run off non-horizontal surfaces. Particularly when the peroxygen compound is a soluble peracid, the compositions are difficult to thicken successfully, because many commonly available thickening systems for aqueous media either fail to thicken them or are decomposed and/or decompose the peroxygen compound substantially during storage. The peroxy compositions, preferably those containing a soluble peracid, arc thickened with a thickener system comprising a dinonylphenolethoxylate of EO (number of ethylene oxide units) from 4 to 8 in conjunction with a micelle-forming co-surfactant. A preferred cosurfactant comprises an amine oxide or a mixture of an alcohol ethoxylate and a polyether. Preferred peracid solutions include dilute equilibrated peracetic acid solutions. The solutions, when thickened to form a viscous liquid, are suitable for disinfecting and cleaning hard surfaces and when thickened to form a gel are suitable for suspension in an aqueous medium, for example in block form.

Patent GB-2266546-A (GB)
Title: Sub-sea well installation.
Inventor: PEARSON ROBERT COLIN
IPC: E21B43/01
Filed: 1992-07-28
Abstract: Pressure gas from a source 3 at an offshore platform 1 passes via a conduit 8 to power a prime mover such as a turbine 13 at a sub-sea well-head 10. The turbine 13 drives an electricity generator 14 which may, for example, power valves 19 and 32 to 35 at the well-head. In another embodiment (not shown). for example, the pressure gas may power a prime mover generating hydraulic pressure supply for the actuation of such valves. In order to reduce the amount of energy which must be supplied from the platform, the gas passes via one or more heat exchangers 36, 38 which transfer heat energy from the well product in a transfer line 31 to the gas to assist in powering the prime mover. The exhaust gas from the prime mover, as the turbine 13, may also pass via a further heat exchanger 40 to receive heat from the well product in order to prevent freezing at the sub-sea exhaust port. In other proposals (not shown) exhaust from the prime mover 13 may be used to cool equipment at the well-head such as actuator 18, or to generate hydraulic pressure for operation of sub-sea hydraulic equipment. <IMAGE>

Filed: 1993-01-15
Abstract: The receiver Rx in a communication system includes a magnetostatic wave device 14 which is configured so as to modify signals having an amplitude above a predetermined level with respect to signals having an amplitude below the predetermined level. A transmitter Tx is operative to randomly frequency hop a carrier signal 3 over the bandwidth of a broadband noise signal 6 and, as long as the amplitude of the received signal is above the predetermined level and the average broadband noise level is below it, the former is attenuated less and the signal can be retrieved without any synchronisation between the transmitter and receiver. In another embodiment, a receiver includes a parallel arrangement of two such devices and the transmitter is operative to randomly hop two information carrying signals over a frequency band. The information can then be retrieved by a respective one of the devices. <IMAGE>

Title: Digital transmission system with an error code across the frequency domain
Inventor: DE BOT PAULUS GEORGE MARIA
IPC: H04L27/26
Filed: 1994-01-14
Abstract: There is described a transmission system for transmitting digital information on a combination of frequency specific channels that are channelwise subject to burst errors. The transmitter has an encoder for adding first redundant informations to a block of two-dimensional information, transverse to the channels. The receiver has detection means for selectively assigning channel pointers to channels that appear less reliable. Next, within the block first-dimension code words are disposed transverse to the channels for on the basis of the pointers executing a symbol-per-channel correction. The pointers may be generated either through a second code that together with the first code constitutes a product code. Alternatively, the receiver comprises a detector for detecting a channelwise fading quantity, or a co-channel interference quantity. <IMAGE>

Title: Page turning special effects device
Inventor: NAKATA TETSURO
IPC: H04N5/262
Filed: 1995-04-27
Abstract: In a special effect picture device, a transformed picture which is non-linear with respect to an original signal is formed using a video signal and a key signal for the original signal. A video signal is stored in a video signal storage unit (1) and a key signal is stored in a key signal storage unit (2). Read-out addresses for information concerning an upper picture of the transformed picture, information concerning a lower picture of the transformed picture, and information concerning depth are generated by a read-out address generating unit (5 - 7). A key signal read out from the key signal storage unit (2) and a video signal read out from the video signal storage unit (1) are divided (8a, 8b) into upper and lower key signals and upper and lower video signals responsive to the read-out addresses for the upper and lower pictures. The upper and the lower pictures are combined by a picture combiner (9) using the upper and lower key signals and the divided upper and lower video signals. The combined picture is freed of the stepped notch edge effect at the page fold by processing the key signals in accordance with depth information generated by the read-out address generating unit. <IMAGE>
