Title: Device for calibrating and evaluating signals from exhaust gas oxygen probes
Inventor: HOETZEL GERHARD
IPC: F02D41/24
Filed: 1994-12-21
Abstract: A heated amperometric oxygen probe comprises a heater 18 and a probe signal measuring device which applies a predetermined voltage to the probe and ascertains as an uncorrected measuring signal S_N, a value representing the current which is flowing through the probe and which is indicative of the oxygen concentration. The resistance of the probe at a given temperature increases with age so that the measured current signal may be lower than the correct value. To compensate for this effect, the evaluation device measures the internal resistance of the probe by applying an a.c. voltage to the probe from circuit 20, and controls the voltage Uh applied to the heater 18 of the probe in such a way that the internal resistance of the probe remains substantially constant. A calibration and compensation device 22 stores, in a predetermined calibration operating state of the engine, a value Uh-0 which is indicative of the heater voltage required when the probe is new, and, in the same calibration state, determines the heater value Uh-M which is currently required to achieve the said internal resistance. A correction value determination device determines, from the change between Uh-0 and Uh-M, a correction value KF for correcting the measuring signal, and correction device 23 corrects the uncorrected measuring signal S_N to a corrected measuring signal S_K. <IMAGE>

Title: Bistable actuators
Inventor: MCKEAN BRIAN
IPC: H01H47/22
Filed: 1995-04-11
Abstract: The actuator comprises an armature which is moveable between a first bistable position and a second bistable position, a first driving coil 62 for driving the armature from the first to the second bistable position when the first coil is energised and a second driving coil 60 for driving the armature from the second to the first bistable position when the second coil is energised. The actuator includes a circuit which energises the non-driving coil as a braking coil to partially oppose the magnetic driving force of the driving coil, during at least part of the period when the driving coil is being energised. This enables a high degree of control to be exercised over precisely when, and how fast the armature starts moving. By varying the power applied to the braking coil, it is possible to vary the velocity of the armature during its stroke, thereby rendering it possible to operate dual circuit breaking devices which require a combination of a short fast stroke and a long slow stroke sequentially.
Patent GB-2292072-A (GB)
Title: Castor assembly
Inventor: BROWN BARRY
IPC: B60B33/02
Filed: 1995-07-14
Abstract: A castor comprising a castor wheel 10 which is freely rotatable about a generally horizontal axis afforded by a support member 11 which is itself swivelable about a generally upright axis, which is offset from said horizontal axis, the upright axis being defined by a head member 12 wherein restraint means are provided which is operative in at least one orientation of the support member relative to the head member. The restraint means may comprise a ball 33 or other detent element carried by the support member and biased by a spring means 34 into engagement with an annular surface 29 at the underside to the head member 12 and concentric with the swivel axis 13. The surface 29 is formed with a recess 30 so dimensioned as to receive the ball 33 and thereby provide resistance to swivelling movement of the wheel 10 from the preferred orientation, which resistance can be overcome by the application of torque to the support member relative to the head member about the swivel axis. The castor assembly may be supplied as a kit for conversion of conventional castor assemblies. <IMAGE>

Title: An adjustable watch strap
Inventor: TSE WAI-HANG
IPC: A44C5/10
Filed: 1995-09-08
Abstract: The strap is provided with a number of removable link members 13 which are separated by removing parts 21, 22 and a spacer 25. A laterally slidable peg 15 normally holds the spacer 25 in position, but when a spacer is removed, pivot connecting parts 21 and 22 can slide inwards towards each other and out of engagement with link members 14. This allows those link members to separate. In this way, some or all of the link members can be removed to adjust the overall length of the strap.

Title: Control method and apparatus for a centrifugal chiller using a variable speed impeller motor drive
Inventor: SULLIVAN BRIAN T
IPC: F25B1/053
Filed: 1994-07-08
Abstract: A controller (26) for controlling the capacity of a centrifugal chiller compressor (12). The compressor (12) is driven by an electric motor (13) and has variable inlet guide vanes (29) that control the flow of refrigerant to the compressor (12).

Title: Double Pivoted Cantilevered Support Arm
Inventor: CHRISTIAN PHILIP
IPC: F21V21/26
Filed: 1996-10-08
Abstract: A double pivoted cantilevered support arm with a lower arm 6 which has fixed discs at both ends, is pivoted at the centre of the bottom disc 5. The top arm 10 is pivoted at the centre of the top disc 7, and supports a lamp. The disc diameters are proportional in dimensions to the maximum balancing torque at their respective pivots. One tension spring 14 provides the balancing force for both arms, flexible strips 3 and 12 connected to the spring pass over the discs to anchor points 2 and 11. The tension in the flexible strips between the discs and the anchor points provides the reaction force to balance the arms. Moving the arms makes the flexible strips slide over the discs and causes the spring and friction forces to be adjusted, the friction force modifies the tension in the flexible strips to balance the arms.

Title: Telecommunications Management System
Inventor: YEUNG JOEMANNE CHI CHEUNG
IPC: H04Q3/00
Filed: 1997-01-30
Abstract: A server station for managing an item of equipment of a telecommunications system is responsive to control messages from a client application to perform operations in order to manage the item. A plurality of client applications can send control messages to the server station via a management communications network. The server station comprises means for accessing a store of address information for the client applications, an interface for receiving a message from a first client application, and means for determining whether the message is a control message for the server or a message destined for a second client application. A router, responsive to the interface determining that the message is destined for a second client application uses the address information to re-route the message via said management communications network to the second client application. By this approach, the actual management communications network used by the client applications to manage items of equipment via one or more server stations is also used for the transmission of messages between users of the client applications, the server station being used as a router for these messages.

Title: A Non-Reusable Syringe and Needle Assembly.
Inventor: JENTZEN WILLIAM
IPC: A61M5/32
Filed: 1997-09-15
Abstract: There is provided a non-reusable syringe 10 and needle 300 assembly characterised in that a cutting blade 700 is provided in the plunger 200 for actuating a needle retraction mechanism. A hollow plastic plunger is frangibly connected to a tubular housing 602 with engaging means for an elastomeric sealing element 601. In use additional pressure applied at the end of the plunger stroke causes the plunger to shear away from and/or move within the tubular housing so that the cutter penetrates the sealing element and engages the spring lock 34 of a spring housing 30. Concomitant cutting of the spring lock thereupon allows a biasing spring 400 to release the needle into the plunger. A number of alternative arrangements for frangibly connecting the plunger to the tubular housing and/or the sealing means are additionally disclosed. One further aspect of the invention comprises a locking means 207, 106 for securing the plunger in the barrel at the end of its operation.

Title: Characterising the inputs and outputs of an integrated circuit
Inventor: FLYNN DAVID WALTER
IPC: G06F13/42
Filed: 1993-08-23
Abstract: An integrated circuit (IC) can be supplied with an early or a delayed clock signal depending on whether data transfer is being conducted within the IC or between the IC an external unit respectively. Both these clock signals stem from an external clock signal applied to Xin. The delayed clock signal is supplied by buffers 180 & 200 in normal operation. In a test mode, the buffer 180 is disabled and a test clock signal is applied to the Xout pad and data is exchanged with the IC using a standard circuit analyser. Using the analyser, the data inputs of the IC can then be characterised using the test clock, and the data outputs using the early clock.
