Title: Packet switched communications network
Inventor: PORTER JOHN DAVID
IPC: H04L12/70
Filed: 2001-08-09
Abstract: A packet switched communications network comprises a controller (11) and a plurality of controlled units (12, 13, 14) arranged in a ring. Each of the controlled units comprises a switch (31) at its input, the switch including control means (32) responsive to control instructions contained in packets transmitted by the controller (11). The control means (32) is arranged to configure the switch (31) so that in a first configuration (1,1) the switch (31) passes control instructions and data into or out of the controlled unit (12, 13, 14) and in a second configuration (2,2) the switch (31) bypasses the unit (12, 13, 14) and passes the control instructions and data to a further controlled unit (12, 13, 14) connected to the controller (11) or back to the controller (11).

Title: Encoding the data on the IEEE1149.1 5 wire interface
Inventor: HORWOOD PETER
IPC: G01R31/3185
Filed: 2002-01-09
Abstract: By utilising a higher rate clock than the required TCK frequency it is possible to encode the IEEE1149.1 interface data and transmit the information serially along the same 5 connections or less), thereby improving signal integrity. The actual number of physical connections required is dependant on the physical media chosen. By encoding the IEEE1149.1 data it is possible to increase the total number of data bits to be encoded so that additional data may be transmitted at the same time. A logical extension of this is the possibility of additional data at the same time as transmitting IEEE1149.1 data. The interface may also be used to provide a stand only generic communication interface to either a PCB or a system.

Title: Rocker arm assembly
Inventor: JOHNSON MATTHEW K
IPC: F01L1/12
Filed: 2002-01-30
Abstract: A rocker arm assembly (100) includes a rocker arm (102) that forms an adjusting mechanism bore (114), an insert bore (118), and a transverse central bore (108). An adjusting mechanism (116), e.g., a screw, is installed in the adjusting mechanism bore (114) and is used to adjust the travel of the rocker arm (102) as it pivots about the central bore (108) during normal operation. An insert (120) that has a hemispherical end (126) is installed in the insert bore (118). Additionally, a button (122) that forms a hemispherical chamber (130) that is sized and shaped to receive to the hemispherical end (126) of the insert (120) is press fitted onto the insert (120). As the rocker arm assembly (100) pivots about the central bore (108) the button (122) rotates with respect to the insert (120). The cooperation of structure between the insert (120) and the button (122) allows the button (122) to rotate with respect to the insert (120), but prevents the button (122) from falling off the insert (120) and damaging the engine in which the rocker arm assembly (100) is installed.

Title: Public-key cryptosystem
Inventor: GALLEY CLIVE NEIL
IPC: H04L9/30
Filed: 2002-08-10
Abstract: This document gives a system for public-key cryptography; i.e. encryption and decryption of messages. There are three private keys, and one public key, to be chosen from an expandable table of keys. We give a simple algorithm for this system. The intractabilty of breaking the encryption is proportional to the size of the keys, and may be adjusted by choice of keys. The keys may also be used to derive fractionally based logarithms of negative numbers. The technique we use to do this is a new generating method for accurate prediction of two unrelated exponents of two unrelated mantissi. The primary generator of the predicting keys in our table below is 0.8745652 which is derived from the comparison of determinism and non-determinism.

Title: Angina medication dose dispenser with log and analysis means for the diagnosis of risk of myocardial infartion
Inventor: WALD DAVID
IPC: G16H50/30
Filed: 2003-01-23
Abstract: The device includes specific spray means (Figs. 6 and 7) or has variable support means (See Figs. 2 and 3) for holding spray dispensers of different sizes. A sensor 27 detects every time spray cap button 25, 32 is depressed to release a dose of medicament. Each dose release event is then logged in time to the memory of a microprocessor 40. An algorithm program run by the microprocessor compares the frequency and quantity of the dose release events to specific parameters such as predetermined thresholds or background rates predetermined by a physician for a patient or type of patient. If the frequency and quantity of the logged events deviate from the specific parameters by specified amounts, then the device emits a warning signal to the user that can be audible, or visible such as an LED light or a display message on the panel 13. The device is battery operated 14, has a port 17 (See Fig. 4) for data transmission, and can also be used with other dispensing units such as pill dispensers.

Title: Intake system for internal combustion engine
Inventor: INO MASAO
IPC: F02M35/10
Filed: 2003-03-06
Abstract: An opening 5 for connecting an air connector 2 and a surge tank 3 is provided such that a centre point of the opening 5 is equidistant from the centres of the two farthermost intake ports 6a. The air connector 2, the surge tank 3, and the opening 5 are arranged so that the major flow direction of the intake air flowing in the air connector 2 is different by a predetermined angle from the major flow direction of the intake air entering the surge tank 3 through the opening 5. A gas introduction portion 4 (eg for EGR gases, blow-by gases or fuel vapour) is located on the air connector 2 upstream of the opening 5 and further from the throttle valve 1 than the opening 5. Gas is discharged from the gas introduction portion 4 in a direction B opposite to the flow direction A of the intake air in the air connector 2 so that the introduced gas tends not to stick to the throttle valve 1, reducing the probability of throttle valve failure. The mixing efficiency of the intake air with the introduced gas is enhanced before the mixture enters the surge tank 3 and, hence, the air-fuel ratio of the mixture fed to the independent ports 6 becomes even.

Title: Time slicing between adjacent cells in a wireless communication network
Inventor: AALTONEN JANNE
IPC: H04H20/67
Filed: 2003-06-24
Abstract: In a DVB-T network, a single channel is shared between transmitters 11-17 associated with adjacent cells on a time-division basis. Timing allocation information signals are received at each transmitter 11-17, where it is determined therefrom and from a common time reference, such as a GPS receiver or atomic clock, when transmission is and is not allowed. Each of the transmitters 11-17 then transmits on the channel at different times. The channel may carry Internet Protocol Data Cast Services. The timing allocation may be varied so that transmitters have unequal shares. The allocation may be dynamically controllable depending on demand. Using the invention, a saving of frequency spectrum is obtained without requiring channel rasterisation.

Title: Producing marbled sweets using nozzles with flow divider
Inventor: QUEALLY PETER
IPC: A23G1/20
Filed: 2003-09-12
Abstract: Chocolate sweets (1, Fig. 2 and 3) with a marbled effect are formed using a nozzle having an inner nozzle part 2 for a first tempered chocolate 10 and an outer nozzle part 3 for a second tempered chocolate 11. The inner nozzle pan 2 is spaced radially inwardly of the outer nozzle part 3. Bridging elements comprising wires 6, 7 extend across the nozzle outlet 5 in a cruciform shape to interrupt the outlet and divide the flow path. The injection of dark chocolate 10 through the inner nozzle part 2 and the injection of the white chocolate 11 into a gap 12 between the inner and outer nozzle parts 2, 3 coupled with the bridging wire elements at the nozzle outlet results in the simultaneous deposition of white and dark chocolate 10, 11 to produce a marbled effect. The amount of white to dark chocolate dispensed can be varied by setting the injection pressures. The weight ratio of the white to dark chocolate injected into a chocolate-forming recess 20 of a mould 25 may be from 1:10 to 1:15 to produce a quality marbling effect.

In a another embodiment the sensitivity of the loop may vary as a vehicle moves along the roadway. The width and depth of the loop may vary along the length. The loop may also have additional conductors for changing the sensitivity of the loop in specific areas. In both embodiments the loop may be able to determine the direction of a vehicle. In use the loop is disposed along a roadway or hard shoulder to detect the presence of vehicles and may be connected to a traffic management system and a plurality of electronic signs for indicating if a lane may be used by running traffic.
