An air intake for a jet propulsion engine comprises a casing and a centre body which define therebetween an annular air intake passage, the centre body being formed by two separate outer surface portions disposed end to end axially of the air intake, the adjacent ends of the outer surface portions being hingedly connected together and being simultaneously radially adjustable. In the embodiment shown the intake comprises an outer casing 10 and a centre body 11, the centre body being formed of a forward portion 13 of frustoconical shape and a rearward portion 14 also of frusto-conical shape, the portions 13, 14 being supported on a central tubular member 17 which is secured to the outer casing 10 by means of hollow struts 62. A conical tip 30 is provided forwardly of the assembly. The forward portion 13 comprises a series of T-section struts 24 which alternate in circumferential assembly with box-section struts 25 as shown in Figs. 2a and 2b, the rearward portion being similarly formed of struts 24<SP>1</SP> and 25<SP>1</SP>. The struts 24, 25 are hingedly connected to the tubular member 17 at the forward end and the struts 24<SP>1</SP>, 25<SP>1</SP> are connected to the tubular member 17 at their rearward ends so as to permit axial sliding of the struts with respect to the tube. The struts 25 and 25<SP>1</SP> are hingedly connected together at their adjacent ends by hinge members 40. Frustoconical cam members 15, 16 are disposed within the adjacent ends of the strut assemblies 13, 14, the cam members engaging rollers 36, 36<SP>1</SP> mounted on brackets 37, 37<SP>1</SP> secured within the box-section struts 25, 25<SP>1</SP>. The cam members 15, 16 are connected by spider members 45, 46 to piston rods 48, 49 secured to pistons 50, 51 disposed within a cylinder 52. When fluid under pressure is supplied through line 57 to the space between pistons 50, 51, the cam members are moved axially away from each other and the struts 24, 25 and 24<SP>1</SP>, 25<SP>1</SP> are moved outwardly about their pivotal points so that the members 13, 14 take up positions as indicated in broken lines in Fig. 1. When the fluid pressure is released the strut members return to the initial position. Boundary layer air may flow through the gap between the strut assemblies 13, 14 and pass through openings 60 into the tubular member 17 and discharge therefrom through the struts 62. The invention is applicable to air intakes for both gas turbine jet engines and ram jet engines.

Title: Transmission power control method
Inventor: TRANDAI ANHTUAN
IPC: H04B7/005
Filed: 1998-01-21
Abstract: A transmission power control method subdivides one or more transmission power steps as defined in a system specification into multiple sub-steps. A base station instructs a mobile station to use a defined power step, and the mobile station initially selects a maximum power sub-step within the requested power step during an initial RACH transmission. During the duration of the call, the mobile station dynamically adjusts the power sub-step based on measured signal reception quality and channel conditions. The result is an improvement in call completion rates with only a minor reduction in battery life.

Patent GB-2334575-A (GB)
Title: Environmental monitor and alarm having an updated allowable measurement range
Inventor: DARROCH JANICE IRENE
IPC: G01N33/18
Filed: 1998-02-19
Abstract: An environmental monitor (10) repeatedly takes a sample from a substance to be monitored and measures a parameter of that sample. The value of the parameter is stored in a memory (32). Once a number of measurements have been made and stored in the memory (32), a calculator (34) within a processor (30) generates a range of permissible values based upon the stored measurements. The processor (30) compares subsequent measurements with the permissible range and, if a given value lies outside the range, an alarm (40) is triggered. In a first embodiment, the range is updated each time a new measurement is made. In an alternative embodiment, the range is only updated when the alarm (40) is triggered. The monitor (10), which is particularly suitable for monitoring the toxicity of waste and potable water supplies, thus provides a moving window of control limits, to minimise the risk of false alarms from naturally occurring background variations in the parameter measured. The measured parameter may be a bio-luminescent signal.

Title: Spray dispenser with collapsible container
Inventor: WHITE THOMAS DAVID
IPC: B05B11/00
Filed: 1998-09-15
Abstract: The dispenser has a collapsible, liquid impermeable container 4, eg a bag or pouch, and an extraction arrangement, eg with a hand actuated trigger pump, for extracting liquid from the collapsible container 4 and dispensing the liquid as a spray. A seal is arranged to prevent air ingress into the collapsible container 4, the seal and extraction arrangement being such that the extraction arrangement is operable to dispense the liquid whilst the seal is in the sealing position. The collapsible container 4 collapses as liquid is dispensed, resulting in little or no back pressure (vacuum) existing in the flexible collapsing container; this inhibits ambient air being drawn into the collapsible container. The dispenser is thus suitable for spraying sterile or reactive fluids, eg in clean room environments such as hospitals, pharmaceutical or food preparation areas.

Title: A method of returning boil off gas from stored cryogenic liquified gas to its liquid phase
Inventor: BROWN RICHARD ALLEN
IPC: F17C9/00
Filed: 1998-12-21
Abstract: An installation 2 for the storage and supply of a cryogenic liquefied gas, for example liquefied natural gas, comprises storage tank 4 for the liquefied gas at low temperature having an upper internal region 4a in which the boil off gas collects. That boil off gas is supplied by pipe 10 to an inlet 8 of a liquid jet pump or liquid jet compressor 6. Liquefied gas is conveyed from the tank 4 by pump 22 and pipe 20 to a jet 14 of the jet compressor 6. The boil off gas is entrained by the cold liquefied gas leaving the jet 14 in a venturi 16 to form a stream, the pressure of which is higher than that of the supply pressure of the vaporised gas so that the gas resumes its liquid phase, and the liquefied gas is raised to high pressure by high pressure pump 30 for onward supply.

Title: Microprocessor-controlled fuel energizer with magnetic field produced by a coil
Inventor: SHETTLE ROBERT WALTER
IPC: F02M27/04
Filed: 1999-01-28
Abstract: The fuel energizer has a body 1, which houses the electronic components including the microprocessor. The cable 3 is wound around the main fuel line within a vehicle to form a closed loop coil 3(A), and is plugged into the unit 1 via the plug 4 and socket 2. The supply cables 5 are then connected to the battery of the vehicle, to power the unit. The status light 6 will then start to flash to indicate that the unit is functioning correctly. Once the unit has been installed, the computer program will first check whether the unit has been installed correctly; if so the computer will start to generate a swept frequency output signal that is amplified by a power transistor, which supplies the signal to the output coil. The output signal will sweep up from 1 kHz until it reaches 7.5 kHz, and then starts to sweep down from 7.5 kHz to 1 kHz, it will keep doing this in a continuous loop until the power is removed from the unit. The key elements of the invention are the design of a closed coil, used to produce the magnetic field, and the use of a microprocessor for the generation of the swept output signal that is required to break up the hydrocarbon chains within the fuel and also for the transfer of kinetic energy to the hydrocarbon molecules.

Title: Load balancing client requests amongst a plurality of servers
Inventor: JACKSON BRUCE
IPC: H04L29/06
Filed: 1999-11-30
Abstract: A gateway 10 receives a request from a client 930 and generates a request parcel containing the request and predetermined control information used to identify the request. Requests are placed in a store 20 which may be a FIFO buffer. A plurality of servers 920 each has an associated resolver 30 for requesting from the store a request parcel. Upon receipt of the request parcel the resolver extracts the request and passes it to the associated server for processing, and passes the control information to the gateway to enable data generated by the associated server to be routed to the client. Requests by resolvers for request parcels from the store may be made dependent upon the loading of the associated server. The resolver may provide a number of resolver threads, each thread being arranged to request a request parcel from the store. The number of threads is controlled according to the loading on the associated server.
