Filed: 1995-12-22
Abstract: A portable radio telephone apparatus includes a first memory and a second memory for storing variable length records (eg names and telephone numbers) and validity confirmation indicators, indicating confirmed or unconfirmed validity, associated with each record. Memory defragmenting is achieved by identifying a first record in the first memory means which is adjacent an available memory fragment; providing a second record 16' in the second memory means which is a duplicate of the first record having its validity confirmation indicator set to unconfirmed validity (Fig 5a); setting the validity confirmation indicator of the second record to confirmed validity; setting the validity confirmation indicator of the first record to unconfirmed validity (Fig 5b); providing a third record 16'' in the first memory means at the location of said available memory fragment having its validity confirmation indicator set to unconfirmed validity; setting the validity confirmation indicator of the third record to confirmed validity; and setting the validity confirmation indicator of the second record to unconfirmed validity (Fig 5c).

Title: Determining bandwidth capacity for different traffic QOS classes in a connectionless communications network
Inventor: MAUGER ROY HAROLD
IPC: H04L12/70
Filed: 1997-08-01
Abstract: A connectionless network capable of accommodating various grades of quality of service (QOS) is operated and controlled by a virtual model of the network. Bandwidth capacity for different traffic QOS classes is determined within the virtual model and transferred to the physical network by determining the relationship between the physical network and virtual model. In a non-geostationary satellite network the virtual model comprises a mesh of connected virtual nodes. As the satellites move, each node becomes embodied by different satellites. Routing of connectionless packets is performed in the virtual network. Modelled virtual paths are chosen with bandwidth satisfying QOS requirements. For class 1 and class 2 QOS, calls are admitted only if sufficient bandwidth is available. The chosen modelled virtual path may be embodied by a number of possible paths in the real network, each being predictable as they relate to the motions of fixed satellite orbits.

Title: Dilution System For Filling Spray Bottles
Inventor: THOMAS JOHN E
IPC: B67D1/00
Filed: 1995-12-18
Abstract: The invention relates to an apparatus for diluting liquid concentrate materials to liquid use solutions. An aspirator system (16) is adapted to receive a container (11a) of liquid concentrate in a reservoir (10). The reservoir contains means (13) to open the liquid concentrate. Additionally the reservoir contains means to support the liquid concentrate during addition of concentrate to the reservoir. When empty, the liquid concentrate bottle can be placed in a reservoir for the empty container (11b). The receiver has filling means for the container that can deliver dilute use solution to the container. The liquid concentrate container and the dilute use solution container are substantially identical. The apparatus is controlled using a flow controller (14) that activates liquid diluent causing the liquid diluent to pass through the aspirator drawing concentrate at a fixed dilution ratio. The aspirator can be used in a station with multiple apparatus, each adapted to a particular liquid concentrate and dilute use solution. The typical container for such a station comprises a plastic bottle (11) having a fitment adapted to the receiver opening means. The preferred container for the liquid concentrate contains a fitment comprising a closure for the bottle opening having impressed into the closure a circular indent operatively connected with a thick hinge member. When inserted into the reservoir, the opening means causes the fitment to fail at the circular indent resulting in a clean separation of the circular portion from the closure permitting the contents of the concentrate container to drain into the reservoir.

Title: System and method to improve the quality of reproduced images on a film to video transfer device
Inventor: SPEARS STEVEN
IPC: H04N9/11
Filed: 1996-04-08
Abstract: A system and method to improve the quality of reproduced images on a film to video transfer device (12) by scanning extra lines to reduce vertical aliasing and performing vertical sample rate reduction (61) to produce the correct number of video output lines. This invention also has the effet of reducing high frequency noise as a result of the vertical sample rate reduction which produces a line filtering. In the present invention, more lines are scanned than normal and the distance between lines is reduced so that the larger number of lines covers the original film image area. This has the effect of increasing the sampling frequency in the vertical direction and therefore reducing aliasing. To provide the correct number of lines in the output of the film to video sample, rate reduction is performed. Sample rate reduction is performed by filtering multiple adjacent lines to remove any high frequency content that would be aliased at the lower rate. Lines are discarded in a predefined sequence that is a function of the fractional reduction rate.

Title: A method and a means for preventing deposition of fouling larvae on a ship's hull
Inventor: STLIE LARS STEINAR
IPC: B63B59/04
Filed: 1998-02-20
Abstract: Larvae are prevented from depositing on a ship's hull by having low frequency transducers mounted in pairs on the inside of the hull to create vibrations in the water adjacent to the hull. A method is used with two alternating signal forms; In one signal form the phase of one transducer in each pair is swept in relation to the constant phase signal of the other transducer, in order to create travelling pressure maximum positions in the water along the hull, and in the other signal form, both transducers in every pair are driven synchronously and equally with pulses having a low duty cycle.

Title: Flywheel and clutch plate assembly
Inventor: ALBON RALPH
IPC: F16F15/129
Filed: 1998-10-09
Abstract: A clutch plate comprises a friction plate 32 having an annular disc 34 clamped between two discs 40, 42 of hub 30 by means of two, eg rubber, friction rings 52, 54 which allow the disc 34 to rotate slightly, due to resilient distortion, providing damping of minor engine torque fluctuations. If the engine torque exceeds an upper threshold, the disc 34 slips continuously about the hub, thereby preventing this excessive engine torque being transmitted to a gearbox. In another embodiment, the discs 40, 42 are provided with through holes 45 which allow access to heads of bolts 12, thereby permitting the clutch plate 16 and pressure plate 14 to be mounted to flywheel 10 to form a sub-assembly before the flywheel 10 is mounted to an engine. The friction plate carries a friction lining 36 which is gripped between the pressure plate 14, when urged in an axial direction by conical spring 21, and the flywheel 10.

Title: Telescopic hose and related desludge drive systems
Inventor: SWAN PETER IGNATIUS
IPC: B01D21/20
Filed: 1998-12-03
Abstract: A telescopic conduit, comprising inner conduit tubes 3,3a, with sealing means 9, sliding within respective outer tubes 2,2a, provides means for conveying fluid from a movable point to a fixed point. In a settlement tank that accumulates sludge on its floor, the conduit conveys the sludge from a movable sludge uptake trolley to a fixed exit point e.g. a valve 4a, at each tank end. The drive means for the trolley utilises force by the conveyed fluid, e.g. by differential pressure on the respective means 9 to provide trolley reciprocation. Alternatively, the flow of telescopically conveyed desludging liquid drives a rotary vane hydraulic motor that in turn moves the trolley via reduction drive means, the telescopic conduit having swivel joints for both inner and outer tubes which are lateral of trolley movement.
