Title: Catalyst for cleaning exhaust gases
Inventor: MURAMATSU GYO
IPC: B01J23/10
Filed: 1991-09-25
Abstract: A catalyst is used for cleaning an exhaust gas containing substantially no fine carbonaceous particles and comprising an oxidising atmosphere by virtue of its residual oxygen content. It at least partially removes nitrogen oxides from the exhaust gas by causing unburned hydrocarbons therein to act as agents for reducing them. The catalyst comprises (a) one or more alkali metal elements or compounds thereof; (b) one or more transition metal elements in Group IB, Group IIB, Group VA, Group VIA, Group VIIA and/or Group VIII of the periodic Table (excluding platinum-group elements) or compounds thereof, and/or Sn or compounds thereof; and (c) one or more rare earth elements or compounds thereof. The catalyst may be supported in an exhaust cleaner on a heat-resistant porous body which may also carry a second catalyst comprising at least one platinum-group element or a compound thereof. The preferred alkali metal is K or Cs, the preferred rare earth is either La or Ce and the preferred transition metal Cu, V or Mn.
Patent GB-2248512-A (GB)
Title: Vehicle control system
Inventor: NICHOLLS MALCOLM RICHARD
IPC: G01S13/82
Filed: 1991-09-30
Abstract: In a railway signalling system which uses direct radio communication between trains, each train is fitted with two sensor units (10, 11), one at the front one at the rear. Each unit determines the host train's speed and position. The rearward unit (11) transmits (14) its train speed and position by means of a rearward-directed data signal for detection (15) by the forward unit (10) on any following train within range. The forward unit (10) processes (25, 26, 27) the data received from the train ahead and its own train data to determine whether a hazardous situation exists, and generates a control output (28) accordingly. The speed measurement uses doppler techniques, whereas vehicle position is determined by interrogating passive trackside transponders (12). Operation at millimetre wave frequencies is preferred. <IMAGE>

Title: Assays using albumin-tetrazolium interaction
Inventor: ATKINSON ANTHONY
IPC: G01N33/50
Filed: 1991-10-03
Abstract: A method for reduction of a tetrazolium compound containing the cationic nucleus (I), to produce a ring-opened formazan compound containing the group (II), in which the tetrazolium compound is caused to interact with album in and the tetrazolium compound - album in interaction product is reduced with a reducing agent in an aqueous solution at a pH between 6 and 10. The method is applied to the assay of albumin and reducing agents in samples, in which the amount of formazan produced is related to the presence and/or amount of albumin or reducing agent present. <IMAGE>

Title: Optical time division multiple access ranging
Inventor: HEDDERLY DAVID LESLIE
IPC: H04B7/26
Filed: 1991-12-11
Abstract: In Multistation Demand Assigned Time Division Multiple Access Systems digital information is communicated from a head end to a population of oustations so that all the outstations receive the same stream of digital information and select their traffic from it. Traffic is only sent to and from an outstation when there is a demand for it. As the outstations are at random ranges from the head end it is necessary to know the time of travel for a burst of information so they arrive at the head end sequentially. The traffic dependent free time is consolidated and made available for ranging-in outstations.

Title: Loaded line phase shifter
Inventor: NAKAHARA KAZUHIKO
IPC: H01P1/185
Filed: 1993-06-18
Abstract: A loaded line phase shifter (100) includes a semiconductor substrate (12), a main transmission line (3) quarter-wavelength long disposed on the semiconductor substrate, loaded lines (4a, 4b) connected to opposite ends of the main line, first and second FETs (5a, 5b) with drain electrodes (7a, 10a) being connected to the other ends of the loaded lines and source electrodes (9a, 9b) being grounded, and a resonance circuit comprising a third FET (23) and an inductor (20), connected between the drain electrodes of the first and second FETs. A desired phase shift quantity of the phase shifter is determined by characteristic impedance of the main line, reactance components of the loaded lines, and off-capacitances of the FETs. When the resonance circuit is closed in this structure, the susceptance of the load comprising the loaded lines and the first and second FETs is equal to zero, resulting in a phase shift quantity equivalent to the half of the phase shift quantity obtained when the resonance circuit is open. Therefore, two different phase shift quantities are achieved in one phase shifter, resulting in a small-sized multiple-bit phase shifter. <IMAGE>

Title: Pyrotechnic sheet metal
Inventor: KWAN CHAN SEK
IPC: B60R21/26
Filed: 1993-07-14
Abstract: The material 10 comprises a substrate 11 of porous, vapourpermeable oxidizing polymeric film, for example a halogenopolymeric film eg. PTFE, having a layer 12, 13 of oxidizable material for example magnesium, on at least part of its surface, the substrate and the oxidizable material being conjointly capable of reacting together on ignition. Advantageously at least part of the oxidizing material is accommodated within the polymer pores. The pyrotechnic sheet material burns faster than material comprising solid polymeric film, owing to the increase surface area caused by the pores for contact of the substrate and the oxidisable material. Prior to coating of the substrate with the oxidisable material the pores may be partially filled with an incendiary material such as sodium azide. <IMAGE>

Title: Manhole and drainage gullies
Inventor: AL-ESSA ADEL HUSAIN
IPC: E02D29/12
Filed: 1995-02-07
Abstract: A manhole has a main body defining a lowermost chamber with inlet and outlet pipes, an intermediate passage immediately above and of smaller diameter than the chamber, and an uppermost passage of smaller diameter than the intermediate passage. In addition to a manhole cover, a grating 26 provides a wastage trap in the intermediate passage. The grating 26 is supported on an annular flange 28 and is formed in two halves which are releasably locked together by a locking device 38. The position of the grating 26 is such as to normally obviate or mitigate unauthorised tampering therewith, but is positioned in fresh air and accessible to authorised personnel for maintenance. The grating 26 prevents raw materials and heavy objects reaching the lowermost chamber of the manhole. To allow authorised personnel further into the manhole, the device 38 can be unlocked and the separated halves of the grating 26 removed from the uppermost passage or moved to a non-obstructing location in the latter. A vertical perforated pipe may pass through the grating to allow water to pass down the manhole if the grating becomes blocked.

Title: Confined space telecommunications system; transmitter power control
Inventor: STUBBS NICHOLAS JOHN
IPC: H04B5/00
Filed: 1995-04-28
Abstract: A telecommunications system for use in confined spaces, such as tunnels, has radio transceiving stations 18 to 26 interconnected by an optical fibre landline 16 to form a series chain, and a base station transceiver 14 for feeding a signal to the line 16. The radio signal from the transceivers 18-26 is propagated via a leaky feeder 12 or via respective antennas (41 to 45, Fig.3). Each transceiving station 18-26 has means for causing the output power of the signal it propagates to be increased when monitoring means (30,Fig.2) in the station senses a deterioration in the performance of at least one neighbouring transceiving station. The monitoring device (30) may sense power failure, signal strength variations, and/or amplifier bias current. To perform a system health check, a personal computer (50,Fig.4) causes a paging signal to be applied to the leaky feeder 12 via base station transceivers (BS1 to BS10), and the signal propagated by the feeder 12 is picked up by a portable transceiver 48 by means of an antenna (54) or by means of a hard wire connection to the feeder 12.
