Title: Apparatus and method for enabling elements of a phase locked loop
Inventor: GILLIG STEVEN FREDERICK
IPC: H03L7/08
Filed: 1994-10-11
Abstract: An apparatus and method enables elements of a phase locked loop (PLL) (300). The PLL (300) includes a plurality of elements (202, 203, 204, 205). Each element produces an output signal (207, 208, 209, 116 or 117). Each element has a response time t3-t2 defined by the difference in time between a first time t2 at which the element is enabled and a second time t3, occurring after the first time t2, at which the output signal of the element reaches a steady state condition. A voltage controlled oscillator (204) of the plurality of elements, having a first response time t3-t2 is enabled at the first time t2 responsive to a first control signal (302). A loop divider (205) of the plurality of elements, having a second response time less than the first response time t3-t2, is enabled responsive to the first response time t3-t2 and a second control signal (303). The present invention advantageously provides fast lock time for the PLL (300). <IMAGE>

Title: Remote control system; smoke alarms combined with lights
Inventor: MOORE ROBERT WILLIAM
IPC: H05B37/02
Filed: 1996-02-20
Abstract: A remote control system has a control unit 10 which interrupts the mains AC waveform for a predetermined period immediately following a current reversal, and a detector 13 which senses the interruption to control a load 14, particularly a light that is connected to a mains powered smoke alarm assembly 11 which replaces a ceiling rose. The control unit 10 replaces a wall box switch and may selectively insert an interruption in each positive half cycle, the light 14 being on in the absence of such interruptions and turned off when an interruption is sensed. An interruption may additionally be inserted at the start of each negative half cycle, such interruptions being detected to provide an additional control function. Alternatively, control may be dependent on the duration of the interruption. A master interconnect unit (40, Fig.5) may create permanent 60 microsecond interruptions at the start of each positive half cycle, the master unit (40) feeding a plurality of smoke alarm and light systems each associated with a respective control unit 10 which selectively lengthens the interruptions, the light being turned off in response to detection of the longer interruption. If a smoke alarm detects smoke, it applies a DC alarm voltage to the mains wiring in the period when the supply is interrupted. On detection of this alarm voltage, the master unit (40) lengthens the interruptions even further, in response to which all the alarms 11 enter a test mode in which their sounders and lights 14 operate.

Patent GB-2312714-A (GB)
Title: Method of operating a hydraulically-actuated, electronically-controlled unit fuel injector (HEUI) to prevent cavitation at the high pressure valve seat
Inventor: BEATTY DAVID J
IPC: F02D41/40
Filed: 1997-04-07
Abstract: The fuel injector has a solenoid actuated control valve (30, fig.1) mounted in an actuation fluid cavity (13, fig.1). The valve is movable between a first position in which the actuation fluid cavity is opened to a high pressure actuation fluid (eg engine oil) inlet and a second position in which the cavity is opened to drain. In the method, the desired amount of fuel to be injected is determined and an actuation duration for the solenoid corresponding to the desired amount of fuel is calculated. Then, it is determined whether the actuation duration corresponds to a cavitation zone of operation for the control valve. Next an injection event is initiated by moving the valve to open the cavity to the high pressure actuation fluid inlet. After the actuation duration, the control valve is moved toward the position that opens the low pressure actuation fluid drain. If it is determined that the injector was operating within the cavitation zone of operation, then the movement rate of the control valve while closing is slowed while it is moving to close the high pressure actuation fluid inlet eg by an additional current spike 54 to the solenoid current wave form. This slowing of the valve's closure sufficiently alters conditions within the injector so that pressure at the valve seat, fig.4, does not drop to cavitation levels.

Title: Reciprocating piston engine with Z-crank and double-ended pistons in axial cylinders
Inventor: STOTT WILLIAM MAY
IPC: F01B3/02
Filed: 1998-06-25
Abstract: The engine has a Z-crank with two diametrically opposite axial cylinders containing double-ended pistons which are phases to fire simultaneously. Additional cylinders may be added in similar pairs to give eg 4, 8 or 12 pistons. The use of double-ended pistons reduces crank torque loading and crank end thrusts; the use of a Z-crank reduces the total number of bearings. The performance of very high performance engines can thus be increased by reducing internal frictional losses. To gain further reductions in friction, sleeve valves may be used. Two methods of sleeve valve operation are possible: (a) conventional timed porting, ie eccentric drive with both axial and annular sleeve movement is fixed, or (b) primary sleeve porting fixed by the axial movement of the sleeve and by the use of secondary external valves to control gas flow.

Title: Twin mass flywheels
Inventor: YOUNG ALASTAIR JOHN
IPC: F16F15/131
Filed: 1998-05-08
Abstract: A twin mass flywheel (10) in which first (11) and second (12) flywheel masses can rotate relative to each other about an axis (C) under the control of one or more connection means (50, 31, 41) whose centre of gravity moves radially with respect to the rotation axis as the flywheel masses rotate relative to each other. The centripetal loads acting on the connection means (50, 31, 41) as the twin mass flywheel rotates tend to bias the first and second flywheel masses towards a pre-determined relative rotational position to provide speed sensitive damping of the relative rotation. The connection means may take the form of a mass (50) which moves along a first track (31) associated with the first flywheel mass (11) and a torque transmitting connection acting between the mass (50) and the second flywheel mass (12) in the form of a second track (41) also followed by the mass. Numerous other forms of connection means are also disclosed some of which use links (570) in place of one of the tracks.

Title: Locating transmitter using diagonalization of receiver position matrix
Inventor: BRANDWOOD DAVID HERBERT
IPC: G01S5/02
Filed: 1999-04-29
Abstract: In a method of determining the location of an object (10) transmitting a signal, which method can be used for any receiver array configuration, a receiver array comprising at least three auxiliary receiver elements (22, 24, 26) arranged about a master receiver element (20) is arranged to receive timing data (T<SB>0</SB>, T<SB>1</SB>, <WC 1>T<SB>2</SB>, T<SB>3</SB>) from the object (10) at each receiver element (20, 22, 24, 26). The receiver array is represented in the form of a receiver position matrix and singular value decomposition (eigenvalue analysis leading to diagonalization) is carried out on the receiver position matrix. A diagonal matrix such that the lowest singular value multiplied by an identity matrix is equal to the diagonal matrix multiplied by the matrix of the singular values is utilised so that, for each new set of timing data received at the receiver array, the position of the object (10) can be determined. All receiver elements can be coplanar, or nearly so.

Title: Compensating unwanted coupling
Inventor: FOTI STEPHEN JOSEPH
IPC: H01Q13/10
Filed: 1999-06-28
Abstract: Apparatus for compensating for an unwanted signal 14 transferred between two signal paths, e.g. an unwanted mutual coupling between two antenna 6 and 9, comprises a cross-coupling path 13 transferring a compensating signal from one signal path to the other. The length of the cross-coupling path may be chosen so that the unwanted and compensating signals are in anti-phase and thus cancel. A first embodiment (Figure 2) is a patch antenna (20, Figure 2), excited by two orthogonally polarised signals, where the unwanted coupling is reduced by providing a microstrip edge coupler (3A, Figure 2) between the pair of coaxial antenna feeds (2A and 18A, Figure 2) which are connected to the patch via a four point compensation network (21 and 22, Figure 2). A second embodiment (Figure 3) is an antenna array where the unwanted coupling between adjacent elements (30, Figure 3) comprises cancellation circuits (38, Figure 3) which may again be microstrip edge couplers. A third embodiment (Figures 4 to 7) is another patch antenna (51, Figure 4) where two orthogonally polarised signals are excited via slots (54a and 54b, Figure 4) by a one wavelength circumference closed conductive ring (58, Figure 4) which is fed by two feeds (59, Figure 4) arranged at 90{ so as to cancel clockwise and anticlockwise signals around the ring. The two feeds to ring of the third embodiment may also be closely spaced (59a, Figure 6) and the patch may be provided with a flat or dish reflector 55 and a parasitic element.

Title: Temperature calibration of a thermogravimetric analyser
Inventor: CASATI DONATO
IPC: G01G23/01
Filed: 1999-07-21
Abstract: A sandwich of thin metal foils 201, 203 having different melting points is assembled atop a crucible 205. Weights 207, 209 are placed on each foil. The crucible is then used to calibrate the temperature scale of the thermogravimetric analyser in figure 1. The crucible is placed on the microbalance plate and the temperature is progressively increased while variation of weight and temperature are recorded by computer. When the melting temperature of the first metal foil 201 is reached, the foil will melt releasing the weight 207 which will fall on the bottom of the crucible causing shock to the microbalance (103, fig.1). This shock is recorded and represents the melting point of the first metal foil. As the temperature further increases, the metal of the other foil 203 melts releasing the weight 209 causing another shock corresponding to the melting point of the second metal.
