Title: Improvements in or relating to asynchronous transfer mode communication systems
Inventor: FISCHER WOLFGANG
IPC: H04L49/111
Filed: 1993-11-04
Abstract: An ATM communication system comprising an ATM switch 1 having a plurality of input ports and a plurality of output ports, each of the said input ports being fed from an input port server 2, 3,4, and each of the said output ports being arranged to feed an output port server 8. The input port servers each have a plurality of buffer stores A, B...Z, one for each of the output ports to which said output port data is transmitted through the switch. Each buffer store in the input port servers is arranged to interrogate the output port server with which it communicates by means of a bandwidth request before the transmission of data, thereby to determine whether output port server data handling capacity is available, whereby ATM switch operation during periods of peak traffic is facilitated. The system includes a queuing arrangement for bandwidth requests received during periods when there is no available bandwidth capacity, the arrangement being such that requests are released in a predetermined order when capacity becomes available. <IMAGE>

Title: A backward compatible HDTV recording/reproducing system
Inventor: STROLLE CHRISTOPHER HUGH
IPC: H04N9/804
Filed: 1993-03-04
Abstract: A magnetic tape recording format and recording/reproducing apparatus in accordance therewith, wherein a first information signal is recorded as a first type of parallel slant tracks having a predetermined space between each slant track, and a second information signal is recorded as a second type of slant tracks having a narrower width than the width of the first type of slant tracks on either side of each of said first type of slant tracks. Furthermore, two of said second type of tracks are positioned between each one of the tracks of said first type. Additionally, the azimuth angles of the tracks of said first type alternate between different predetermined values for successive tracks, and the azimuth angles of the tracks of said second type are both different from the azimuth angle of the track of the first type which is positioned between them, and also different from the azimuth angle of the track of the second type which is positioned next to them in the space between the tracks of the first type. This format is particularly advantageous for use in the consumer rental market since it allows one tape to provide both a high definition television signal and a standard VHS signal. <IMAGE>

Filed: 1993-03-16
Abstract: A FIFO memory device is provided for storage of variable-length data items, each including a plurality of data words and a count value indicative of the number of data words included in the item concerned. The device includes: a linear array (53) of storage cells, arranged one after the other in a first direction; a write pointer (52) for specifying the first cell available for the storage of a first word of a new data item; means (50) for extracting the count value from a new data item to be stored; means (50-52) operable in dependence upon the write pointer and the extracted count value to store the first data word of such a new data item in the cell specified by the write pointer and to store any successive data words of the item in respective further cells of the array that follow the first-available cell in the first direction; and means (50-52) operable to read the data word stored in the first cell of the array; the array having means operative, after reading of the data word stored in the first cell, to shift into that cell the data word stored in the cell that immediately follows the first cell in the first direction, and so on for all other cells of the array that currently contain data words. In such a FIFO memory device the write control needed by a host device to store data in the FIFO memory device is simplified. Also, the data items are stored without gaps therebetween, i.e. without dummy (filler) words so that during reading operations no such dummy words, need be handled.
Patent GB-2300271-A (GB)
Inventor: MUSSER KEVIN E
IPC: B60R21/16
Filed: 1994-11-22
Abstract: A method and system for improving reliability of a vehicle crash discrimination system by minimalizing the effect of resonance inherently produced by structural elements of the vehicle comprises using at least two accelerometers (18, 20) mounted to different structural elements (22, 24) of the vehicle. The accelerometers are preferably mounted in close proximity to each other to produce similar acceleration data, but corrupted by dissimilar structural resonance. Signal analysis processing (36) is performed to extrapolate the common acceleration data to generate an output (38) substantially uncorrupted by structural resonance for use in the vehicle crash discrimination system. Detection of operability of the accelerometers (34) can also be performed to provide for switching to a backup mode filtering process (44) to insure operability of the discrimination system upon failure of one of the accelerometers.

Title: Means of locating a car window glass holder to the carrier plate of the window regulator
Inventor: MOSS DAVID
IPC: B60J1/17
Filed: 1996-10-15
Abstract: A carrier plate 3 of a car window regulator is lowered and raised to open and close a window. The lower edge of the window glass is received in the channel of a glass holder 6. The glass holder has a downwardly extending flange 9 which overlaps one side of the carrier plate and fastens to it. A second flange or a projection 16a from the glass holder overlaps the other side of the carrier plate, and may also fit into a recess 18 in the top edge of the carrier plate. This helps align the fixing holes 11,12 and prevents the glass from falling inside the door whilst fastening. Also disclosed is the above assembly, but where the second flange or projection from the holder fits into a recess in the top edge of the carrier plate but which does not overlap the carrier plate.

Title: Self-lubricating valve stem for aerosol containers
Inventor: BURT PETER COLIN WESTON
IPC: B65D83/14
Filed: 1997-06-26
Abstract: An aerosol container, for dispensing metered doses of an aerosol formulation such as medicament, comprises a valve body 1 having a valve stem 7 through which the formulation is dispensed. The valve stem 7 is sealed by a valve seals 9,12. The material of the valve stem 7 comprises a lubricant, such as fluorocarbon polymer polytetrafluoroethane (PTFE) which, due to its low coefficient of friction, acts as a lubricant against the valve seals 9,12. This ensures a smooth operation of the valve, and reduces the deposition of formulation on the valve stem 7 which can cause valve sticking.
