Title: Voltage level shift circuit
Inventor: SELVANAYAGAM SIVANENDRA
IPC: H03F3/50
Filed: 1997-12-02
Abstract: Temperature dependence at the output Vout of a level shift circuit is eliminated by matching Vbe drops in transistors Q10, Q11, Q12, Q13. The right-hand side of an emitter-coupled pair Q10,Q11 is held at a fixed bias current I of half the common emitter current bias current 21, respectively provided by current sources IDC 2 and IDC 1. Any change in the base voltage Vin of the transistor Q10 will therefore cause an equal change in the emitter voltage of the transistor Q11. The transistor Q12 is diode connected and so its base and collector voltage also changes by the same amount. The output voltage Vout at the emitter of the transistor Q13 is at the same level as the emitter of the transistor Q11 due to the transistors Q11, Q13 having the same Vbe drops since the current I through the transistors is the same. The amount and direction of level shift, Vout-Vin, depends on the difference between the resistances of resistors R10,R11 in the emitter paths of the transistors Q10,Q11.

Title: Network management system
Inventor: DAVIS NIGEL ROBERT
IPC: H04Q3/00
Filed: 1997-12-10
Abstract: In a management system of a communications network comprising a plurality of network elements, capacity and capability of one or more individual network elements is represented by a set of data templates (804-806, 807-810). A first set of data templates (804-806) represent internal construction and physical resources of a network element. A second set of templates (807-810) represent connectivity capabilities of the physical resources. The data templates are stored at an element controller, controlling a plurality of network elements (800). The element controller learns about the capacity and capabilities of the network elements, by receiving a set of reference messages generated by the network elements, over an operations, administration and maintenance channel. The reference messages point to the data templates stored at the element controller thereby enabling efficient enrollment of network elements by transmission of compressed messages over the operations, administration and maintenance channel.

Title: Dimensional weighing apparatus
Inventor: DEBARBER CHRISTOPHER
IPC: G07B17/00
Filed: 1997-12-10
Abstract: A dimensional weighing apparatus has a weighing scale (20) for determining the actual weight of a carton (C) placed thereon and associated therewith is a measuring frame (32,34,36) having movable carton contact paddles (66) for measuring the linear extent along the three axes of a carton (C) positioned on the scale (20) necessary to determine the volume of the carton (C). A computer processing means (118) (Fig 7) determines firstly whether the actual volume of the carton is less or greater than a predetermined threshold volume, and if greater, calculates a dimensional weight of the carton volume per unit weight and compares the dimensional weight of the carton with the actual weight to determine which weight is the larger, and sends a signal indicative of the larger weight to a shipping system (124) which calculates a realistic shipping charge. The contact paddles (66) are carried on endless belts driven by electric motors, and current sensor circuits detect the rise in current to each motor as the contact paddles (66) strike the carton (C). An optical sensor detects the extent of movement of the contact paddle (66), and generates pulses.

Title: Multiple beam antenna system
Inventor: TANAKA YOSHINORI
IPC: H04J13/00
Filed: 1998-08-27
Abstract: In a CDMA wireless base station, signals that have been received from a plurality of antenna elements of an antenna array are subjected to a reception beam former to electrically form a plurality of uplink beams. Reception is carried out on the basis of the optimum beam, for example the beam for which the power is maximum. Based upon whether an uplink reception signal is present or not, a controller performs downlink beam forming, thereby forming a downlink transmission beam in a direction identical to with that of the optimum reception beam, or in such a manner that downlink beam forming is not carried out. Additionally a mobile of the system may transmit uplink pilot signals to the base station when a decline in transmission quality is detected.

Title: A method for locating a transponder in an electronic key or smartcard in a motor vehicle
Inventor: BACHHUBER ANTON
IPC: B60R25/24
Filed: 1998-09-02
Abstract: At least two transmitter/receivers 14, 16, 18 are mounted in the vehicle. These send a coded signal to the transponder 22 which replies with a further coded signal. The transponder uses travel time differences or field strength differences in the signals received from the two transmitters to determine its position. Otherwise, the travel time differences or field strength differences in the signals received from the transponder at the two transmitter/ receivers are used to locate the transponder in the car. A further embodiment involves directional transmitter/receivers emitting coded signals. The release component uses the codes to recognise the transmitters from which it is receiving and thus deduce its position (see fig. 3). An indicating unit 20 may indicate whether the transponder is to be found on the left or the right hand side of the car. Also described is a system whereby a single transmitter transmits a search signal and, on receiving this signal, the transponder emits a signal to be perceived directly by a person.

Patent GB-2333346-A (GB)
Title: Extracting energy from a rotating wheel
Inventor: EZISSI CHRISTOPHER
IPC: B60K25/10
Filed: 1999-01-12
Abstract: When the vehicle moves and the roller 7 is at position 360 where the deformation or the tyre flattens because of the weight of the vehicle, this in effect pushes shaft 6 upwards which compresses spring 1 against shaft 9. Because shaft 9 is pivoted with shaft 6 at point 5, the effect of the compression of the spring 1 will push shaft 9 upwards towards the motion of the wheel, this in effect adds more force to the vehicle. When the roller 7 is position at 270, 180 and 90 the spring 1 will expand back bringing the roller 7 vitually in contact with the interior of the tyre surface. As many as these devices that are added to the wheel, the more the energy recovered and reused is. The devices are placed oppposite each other in order to help to keep the wheel balanced. In the event of puncture and tyre repair, all of the bolts will be unscrewed thereby helping the device to be detached and removed from the wheel. The device can be replaced by simply sliding it down through the opening that is covered by plate 8 and bolting it back to the wheel at 10.
Patent GB-2348458-A (GB)
Title: Safety scaffold fitting
Inventor: TIDMAN BARRY JAMES
IPC: E04G7/24
Filed: 1999-01-14
Abstract: The safety scaffolding (clip) fitting comprises a hinged sleeve with a circular cross section, with a bolt to clamp it to a scaffolding tube, and wheels with knurled surfaces are located in both halves of the sleeve. The wheels are designed to grip the scaffold tube in order to stop the clip from moving. Each wheel is attached to the clip by a small bolt, which passes through the wheel slightly off centre. This creates an eccentric movement of the wheel such that a downward load causes the wheel to rotate and move towards the centre of the clips cross-section. Whilst an upward load causes movement of the wheels away from the centre. When fixed on to the scaffold tube any downward load on the clip causes the wheels to exert more force on the scaffold tube in order to resist downward movement. It also means that upward forces reduce this force and hence allows it to be slid up the scaffold tube. The clip is designed so that it may be fixed around a scaffolding tube underneath a coupler, where it will stop the coupler from sliding down the pole should the coupler fail in such a way that might make this movement possible. The clip has been designed such that it will resist downward load with the clamping bolt done up finger tight.

Title: Resistive heating elements composed of binary metal oxides, the metals having different valencies
Inventor: BOARDMAN JEFFERY
IPC: H05B3/26
Filed: 1999-12-10
Abstract: A heating element comprises a conductive metal substrate on which is deposited an insulating layer, a semi-conductive resistive layer of metal oxides, and conductive contact layers. Current flows laterally through the layer of metal oxides between the contact layers. Alternatively, a resistive layer of metal oxides may be deposited directly onto a conductive metal substrate, and current flows from the substrate through the thickness of the oxide layer to a contact layer. The resistive layer comprises binary metal oxides where the two metals have different valencies. The conductivity of the binary oxide system is determined by the compositional ratio of the two metals and by the degree of oxidation. The layer is formed by oxidising particles of a binary metal alloy, heating the oxidised particles to a temperature at which they become at least semi- molten, and depositing the melt onto the substrate or insulated substrate. Conductive contact layers are then deposited. A design example is given.

Patent GB-191420400-A (GB)
IPC: B23B31/16
Abstract: 20,400. Eikar-Werkzeuge Ges. Oct. 4, 1913, [Convention date]. Chucks. - In a chuck of the type in which jaws are adjusted radially and circumferentially in slots in a body by a rotatable cam-shell, the jaws are provided with lugs each bearing on a separate cam-face, the lugs lying in different planes. The body a, which is connected to the shell b by a spring a<1>, has slots f in which the tapered jaws g, h, i are adjusted by cams c, c', d, d<1>, c, which extend almost the entire periphery of the shell so as to increase the range of adjustment. The cams are inserted in or formed on the shell. The jaw h is provided with a semicircular lug h<1> and the jaws g, i with a pair of lugs opposite their respective pairs of adjusting-cams so that the resultant pressures on all the jaws act in the same plane. The upper ends of the jaws have semicircular lugs fitting the slots and forming pivots round which they are moved when the chuck is rotated, which, due to the eccentric faces o of the jaws, causes an increased grip on the tool. The jaws are normally pressed against the driving-side of the slots by spring-pressed pins n', and have ribs l and shoulders k<1> to prevent injury to the jaws and walls of the slots by cuttings. The ends of the jaws are bevelled. The Specification as open to inspection under Section 91 (3) (a) states also that two jaws only may be used, and four cam-faces, the fifth nearest the inlet of the chuck being replaced by a tool-centring guide which closes the inlet when the chuck is not in use. This subjectmatter does not appear in the Specification as accepted.
